How to take urine with a catheter from pregnant women - nutrition, manifestations, recipes, symptoms

In the practice of a urologist, quite often one has to deal with such a device as a urine catheter. It is a rubber tube or a system consisting of several tubes, necessary for insertion into the lumen of the bladder if the patient does not urinate for one reason or another or for other diagnostic purposes.

Most often, catheterization is required for men who have diseases such as prostate adenoma or its malignant degeneration (prostate cancer). Against this background, there is a violation of the patency of the urethra, which leads to urinary retention.

Indications for bladder catheterization

Urinary catheterization is the insertion of a device to drain urine or administer medications. The procedure is performed to diagnose or treat identified urological diseases. Depending on the indications, a catheter is placed temporarily or permanently.

Bladder catheterization is indicated for:

swelling of the urinary tract;
interstitial cystitis;
genital injuries;
cysts in the bladder or urethra;
narrowing, spasms of the urethra;
acute urinary retention;
temporary incapacity;
tumors of the urinary ducts;
blockage of the bladder outlet with stones;
urethral diverticulum;
severe spinal injuries;
postoperative rehabilitation.

Insertion of catheters into the bladder is performed for:

washing the urinary tract and bladder;
obtaining urine for laboratory analysis;
normalization of urine outflow.

The catheter is installed on an emergency or planned basis in the urology department or on an outpatient basis.

Possible complications

Manipulation can lead to the development of complications due to the wrong choice of the type of device, injury to the bladder and infection in the body due to non-compliance with the rules for installing the system.

So, among the possible violations there are:

multiple bleedings;
sepsis;
cystitis;
pyelonephritis;
urethritis;
paraphimosis;
formation of fistulas in the urethra;
damage to the mucous membranes.

Installation of a catheter is a procedure that quite often becomes the only method of normalizing the patient’s condition. A special tube system helps not only to diagnose the patient’s existing pathologies, but also turns out to be necessary in the treatment of these disorders. The main condition for successful therapy is the correct choice of the type of product and compliance with the algorithm for its installation.

When the procedure is not performed

There are relative and absolute contraindications to urinary catheterization. Most of them are associated with the risk of damage to the urinary ducts and infection:

anuria;
exacerbation of urethritis;
acute cystitis;
bleeding from the urethra;
obstruction of the urethra;
acute inflammation of the genitourinary system;
severe spasms of the urethra.

Insertion of a catheter is dangerous in case of strictures (scarring) of the urinary tract. An attempt to catheterize the urethra in case of obstruction of the urethra is fraught with damage or perforation of the wall.

DURING PREGNANCY, I TOOK URINE WITH A CATHETOR AFTER WHICH I BLEEDED!!

“It’s a strange world where two people look at the same thing and see the complete opposite.”
A. Christie “The art of diagnosing is no less important than the art of operating.”

Dear Victoria! And for what purpose did you take urine with a catheter? If there is bleeding, you should urgently contact a gynecologist or urologist. There shouldn't be any blood. You should be prescribed adequate anti-inflammatory treatment.

Types of catheters

Conventionally, all bladder catheters are divided into men's, women's and children's. They differ in length, shape and diameter, which is due to the structural features of the urinary tract in patients of different groups. Depending on the properties of the materials used, catheters are:

Soft. Hollow tubes up to 30 cm long and up to 10 mm in diameter are made of elastic materials. The end of the catheter, which is inserted into the urinary tract, is soft and rounded. The outer end has a funnel-shaped extension, which makes it easier to install the syringe for infusion of medications. When administered, the mucous membrane of the urinary ducts is not damaged. In half of the cases, catheterization of the bladder with a soft catheter is performed for a period of 2 weeks to 3-6 months.
Tough. Solid drainage tubes made of inflexible materials. They consist of a beak, a handle and a rod. The urethral end is rounded with two lateral openings. Insertion of rigid catheters requires special skills and is associated with a high risk of damage to the urethra and bladder neck. The length of a male catheter is 30 cm, and a female catheter is no more than 15 cm.

Depending on the method of installation, the tubes are urethral, external or internal.
Based on the type of design, there are 4 types of catheters:

The Robinson probe is a disposable soft catheter with a small internal diameter and a rounded end. Used to collect urine from women or men with swelling of the urinary tract, dysuric disorders.
The Thiemann stent is a rigid, curved tube with an elastic soft end. It is used to divert urine in case of inflammation of the urinary ducts.
A Foley catheter is a flexible tube consisting of two sleeves and a reservoir for collecting urine. It is used for long-term catheterization of the bladder to empty it and rinse it with medicinal solutions. For long-term bladder drainage in men, self-retaining catheters are used, which are equipped with an expanding balloon.
Pezzera catheter is a large-headed latex probe that is used only in the case of a cystostomy. Sometimes used to drain fistulas in the suprapubic area after surgery.

The type of probes used depends on many factors - the duration of catheterization, the gender of the patient, and the form of the disease.

Using a urine bag

You can take an analysis using a urine collection bag. If there is no special device for animals, you can purchase a device intended for infants at the pharmacy. The edges of the container into which urine will be collected are treated with an adhesive compound. It needs to be fixed in the genital area. Most likely, the pet will be dissatisfied with the presence of a foreign object on the body and will make every effort to remove it. You need to wear a diaper that will block access to the urine collection bag.

This urine collection device should be used as follows:

wash and disinfect hands;
remove the container from the packaging;
remove the protective tape;
secure the container in the genital area;
put on a diaper.

When the container is full, the urine collector is carefully removed, and the urine is poured into a container that must be prepared in advance.

Bladder catheterization methods

The duration of catheterization can be short-term or long-term. In the first case, the probe is inserted into the urinary tract for a period of up to several days, and in the second - for permanent urine drainage.

Types of bladder catheterization:

Urethral - insertion of a stent catheter through the urethra. Performed after antiseptic treatment of the genitals. To relieve pain, a local anesthetic is injected into the urethra. The procedure is performed exclusively in cases of normal urinary tract patency.
Ureteral – installation of a catheter into the ureter. It is performed if it is necessary to collect urine separately from the left and right kidneys. Recommended for stones, as well as for administering medications to the upper parts of the urinary system.

In case of acute urinary retention and urethral obstruction, a drainage tube is inserted into the bladder through the abdomen. A puncture is made in the suprapubic area, into which a stent catheter is installed. If the patency of the urethra is not impaired, the tube is inserted through the urethra.

In what cases is it necessary to use

The process of installing a catheter is organized only according to the indications of a specialist. Most often, such indications are either therapeutic or diagnostic in nature. The first is the presence of pathology of the urinary system in the body. Such dangerous deviations include:

disability characterized by inability to care for oneself;
patient's shock;
urinary retention, diagnosed as an acute form;
transurethral manipulations;
removal of blood in the form of clots from the bladder;
the need for the introduction of antibiotic drugs, as well as antiseptic agents.

DETAILS: Prostate TOUR - transurethral resection of adenoma

The reasons for delayed excretion of waste products may be blockage of stones in the urethra, tumor of the prostate gland, its hyperplasia, or an advanced form of the inflammatory process - cystitis. Quite often this phenomenon is observed during pregnancy or chronic stress.

Preparation for the procedure

Catheterization is preceded by a preparatory stage. Before installing the probe into the bladder, you must:

wash with hypoallergenic soap;
shave hair in the genital area;
wash the genitals with a weak antiseptic solution - Furacilin, Miramistin.

Before the procedure, the nurse disinfects medical instruments. For catheterization you will need:

disposable surgical gloves;
glycerin or petroleum jelly;
scissors;
catheter;
tool tray;
oilcloth sheet;
diaper;
antiseptic;
tweezers;
tray for waste material;
Janet syringe;
gauze napkins;
antispasmodic and local anesthetic;
urinal.

Based on the results of laboratory and instrumental tests, the doctor determines the optimal method of catheterization of the bladder.
Manipulations are performed exclusively under sterile conditions, and during the procedure the medical staff follows antiseptic rules. This reduces the risk of infection of the urinary system.

The importance of taking a bacterial culture during pregnancy

Everyone knows that with the onset of pregnancy, a woman’s body becomes vulnerable and there is a need to be regularly monitored by specialists so that the pregnancy proceeds smoothly and there is no fear for both the mother and the baby.

There is a list of mandatory tests during pregnancy, and one of its items is bacterial culture. Bacterial culture is a diagnostic test in which a sample is placed in a container containing a suitable medium that allows bacteria to actively grow. This test reveals which bacteria are present in the sample, whether any of them are pathogenic, and in what quantity. This study is also carried out in order to establish what types of drugs the bacteria are sensitive to, this is necessary in order to prescribe the most relevant treatment.

During pregnancy, samples for bacterial culture are taken from the vagina (to detect sexually transmitted diseases), as well as the nose (to detect Staphylococcus aureus) and urine. On average, such an analysis takes up to 5 working days.

Why do you need to take a culture test during pregnancy?

Diseases that can be detected by bacterial culture are dangerous for the development of the fetus. Therefore, if there are suspicions, the analysis must be carried out without fail in order to protect the baby and the course of pregnancy.

As soon as you register with the antenatal clinic, one of the first tests will be a urine test to determine Staphylococcus aureus. Urinary infections during pregnancy are the most common and reach 7%. During pregnancy, hormonal levels change and physical changes occur, such as dilation of the ureters. Therefore, most diseases can be prevented in the early stages of pregnancy, in the first trimester.

Bacterial culture of urine will be confirmed

Bladder catheterization algorithm

The procedure for inserting the probe is the same for men and women. But in men, a large part of the urethra is inside the penis, which makes inserting a drainage tube difficult. To reduce pain, patients are given an antispasmodic drug, and the mouth of the urethra is treated with an anesthetic.

Among women

Installing a urinary catheter in a woman is not difficult, due to the structural features of the genitourinary system. To make the manipulations easier, the nurse asks the patient to lie on the couch, bend her knees and spread her hips to the sides.

In women, the urethra is short and wide, so the procedure takes little time.

Technology of bladder catheterization in women:

the nurse washes her hands with antiseptic and puts on gloves;
a tray for waste materials is installed between the patient’s thighs;
the genitals and the mouth of the urethra are treated with an antiseptic solution;
the urethral end of the catheter is lubricated with petroleum jelly or glycerin;
at a distance of 6-7 cm from the edge, the tube is grabbed with sterile tweezers and inserted into the urethra;
it is immersed to a depth of 10 cm or until urine appears;
a urinal or syringe is attached to the free end of the tube to inject an antiseptic (in case of washing the bladder).

At the end of catheterization, the tube is carefully removed. If the urethral muscles spasm, the procedure is stopped.

To prevent injury to the walls of the urethra, the woman is injected with a 2% Papaverine solution.

In men

The algorithm for performing catheterization on a man is the same as in the previous case. But due to the narrowness of the urethra, the procedure takes 2 times longer. It is performed in the supine position and a soft drainage tube is used.

The catheter is inserted into the bladder according to the following scheme:

the patient is asked to lie on his back and spread his legs slightly;
the groin area is treated with an antiseptic, after which the gloves are changed to sterile ones;
the penis is wrapped in gauze;
in the area of the coronary sulcus it is grasped with the fingers of the left hand;
the head of the penis is squeezed with the thumb and forefinger to open the urethral opening;
the probe insertion area is wiped with Povidone-iodine;
the penis is pulled up, perpendicular to the legs;
the inserted end of the tube is treated with Vaseline;
Use sterile tweezers to grab it at a distance of 6 cm from the edge;
with little effort, the catheter is inserted into the penis;
the free edge of the tube is connected to a urinal.

If a permanent catheter is installed in a man, the balloon, which is located on the inner edge, is filled with 5 ml of sodium chloride solution.

After the procedure, the foreskin is carefully returned to its place.

If catheterization is performed once, the stent is pulled out of the bladder a little earlier than all the urine has been removed. This is necessary to flush the urinary tract with the remaining portion of urine.

Features of catheter placement for children

Technically, bladder catheterization in children does not differ from the algorithm of actions for adults. Due to the narrowness of the urinary tract, drainage tubes are installed in the bladder, taking into account certain rules:

the procedure is performed with a full bladder;
the catheter and instruments are sterilized with low allergenic solutions;
The stent is inserted carefully without pressure.

It is undesirable to make more than two unsuccessful attempts to catheterize the bladder in children.

The installation of stent catheters should be performed by a pediatric urologist. If an obstruction is detected in the urinary ducts, the procedure is abandoned. Forcibly overcoming obstacles is dangerous by rupturing the urethra.

Girls who took urine with a catheter

I had a catheter in place during the catheter. There was pain afterwards, there was no blood.

There may be discomfort, but blood is hardly normal. Check with your doctor.

They just scratched your mucous membrane, it will go away

Yes, in 4 days maximum everything will pass.

A few drops is no big deal. Scratched, carelessly inserted. I had the same thing.

Pain is natural, there was an intervention. But... it’s better to consult a gynecologist)

What does the gynecologist have to do with it? Then a urologist)

They put me on a CS, when I was allowed to get up, it started bleeding, a lot, everyone was smart, they ran in, took it out several times and put it in again... horror, then they started injecting some kind of hemostatic... it’s scary to remember, but everything healed over time (((

It will pass, I had it during both CSs. 2-3 days and everything will be fine)

Scratched. It will pass in a couple of days. I had a cystoscopy, and then another 10 procedures of infusion of medication into the bladder. Then a verification cystoscopy. Horror! But she survived everything! In total we climbed 12 times, this channel is terrible.

And they gave me ((thrush (((after childbirth

After childbirth, a urine test is taken with the entire catheter. So this is not an extreme procedure. It’s okay

I understand you, this is a terrible feeling, unpleasant to the bone... It should pass in a couple of days. If not, then there may be an infection, then see a doctor

They put me on CS. I didn’t feel anything at all. And when they pulled me out, I didn’t care, since everything hurt after the operation)))

Elena, no catheter was used to test my urine after childbirth, either after ER or after CS.

Irina, not for everyone, if it didn’t work out on your own

Irina, after the CS I had a catheter, I know, but after the ER there was definitely nothing.

Tatyana, I’ve never heard of someone who has just given birth being told to urinate. The urine was removed with a catheter and the rest of the work was done. If you had an epidural and you can’t do it on your own for a long time, then yes.

This is absolutely normal. Writing will hurt for 2 days. It will also bleed 2. I was also scared then, I even came running to save it. And immediately to the maternity hospital))) and this is for 14 weeks. The doctors in the emergency department of the maternity hospital laughed at me))

Irina, I don’t know about you, but I gave birth and as far as I remember, they didn’t put any catheter in me for ER. Maybe they’re putting something in there now, I had EP 14 years ago.

And I was not diagnosed with either the first or the second birth. And they ask you to go to the toilet as soon as you are transferred to the ward from the delivery room so that the uterus contracts.

Afterwards they performed a cesarean section. Then I felt a little sick and that was all. At this time, everything hurts, you don’t know what else to pay attention to.

. First time I hear, 2 er no catheters at all!! Now after the cop it’s naturally clear. Some kind of analysis? Are tests no longer suitable in a natural way? I wouldn't agree to this

This is how they took a urine test from me. It hurts like hell. But it passes. I didn’t notice any consequences

Anna, if the test is bad several times in a row in the usual way, they take it with a catheter ((

DETAILS: Urine tests for pyelonephritis in women: what tests need to be taken in acute and chronic forms of kidney disease, normal values and interpretation of the results

Elena, you are confusing something)) Don’t scare people. Not everyone and not always have a urinary catheter installed. I gave birth three times (both a very long time ago, 18 years ago, and more recently). There is nothing like it. I don’t know about CS, but with a normal pregnancy and natural childbirth, they don’t do anything, neither in l/c nor in maternity hospitals.

Irina, they told me)

Irina, I’m interested in how you donated urine during postpartum hemorrhage. Yes, this is the practice of the maternity hospital where I gave birth. And I don’t see anything scary in my comment

I don’t understand why I need a catheter during pregnancy. I had to undergo surgery. It was unpleasant, but without consequences.

I had the same thing as you after this procedure

They took me like this during childbirth. Nothing bad should happen

The most miserable procedure that can happen during ber. It was she who discouraged me from the second ber. Crooked hands, what can you do? It will pass on the third day.

Find a good doctor and don't give in to experiments.

Irina, where did they take you and what does thrush have to do with it?

Urinalysis during pregnancy with a catheter is one of the methods used for collecting biological material for research, called catheterization, which gives an accurate result.

Urinalysis with a catheter during pregnancy is a common and frequently used method of collecting biological material, in particular urine, for laboratory research. It’s worth figuring out what kind of method this is, and why it is necessary to use it?

Urine analysis during pregnancy is an important component of all laboratory tests and diagnosing the normal course of pregnancy, and in particular, the good health of the expectant mother. Pregnancy involves constant monitoring and manipulation to collect biological material for analysis.

A complete picture of urine results allows the gynecologist-obstetrician to respond correctly and in a timely manner to the slightest progress in the mother’s health regarding kidney activity, complications during pregnancy and other pathologies.

Conventionally, the entire list of urine tests during pregnancy can be correctly divided into planned activities and studies carried out when pathological changes are suspected. The first include tests for examining women with a normal pregnancy process in the form of standard planned studies:

general urine analysis,
analysis of urine for bacteriological culture.

The second necessary measures for collecting material include:

urine analysis according to Zimnitsky,
Nechiporenko test,
determination of blood sugar levels,
diuresis (daily volume of urine excreted) and others.

Clinical general tests reveal the activity of a woman’s body in full: the physical properties of urine and chemical components are determined. Moreover, in fact, the most important of all the mentioned tests using urine is considered to be bacteriological culture, which every woman should take.

Timely detection of foreign bacterial infections in the genitourinary system is the key to the success of the birth of a healthy child. Infections can cause a number of pathologies, and pathogenic organisms can cause spontaneous abortion.

Of course, urine culture during pregnancy is the most important analysis. Bacteriological analysis correctly identifies the presence of pathogenic microorganisms in the genitourinary system, but also provides the opportunity to determine their sensitivity to antibiotic treatment.

1st trimester – 1 time every 3, 4 weeks,
II trimester – 1 time every 2 weeks,
III trimester – 1 time every week.

When collecting biological material, it is important to correctly follow the rules in order to obtain sterile results for a high-quality diagnosis:

on the eve of urine collection, you should refrain from eating products and substances that can affect the color of the material (multivitamins, beets), and, of course, fried, salted, smoked, sour and alcohol are excluded,
for research you need morning average material collected on an empty stomach,
Urine should be collected in a sterile container: a sterilized glass jar or a special plastic container, which can be purchased at any pharmacy,
Before collecting urine, personal hygiene is carried out correctly: hands are washed with soap and genitals,
The container is delivered to the laboratory within 1.5 hours after collection.

To enable high-quality collection of biological material for research, there is a recommendation from medical workers to prevent microorganisms from entering the material from outside:

when collecting a medium stream of urine, cover the vagina with cotton wool,
insert a small tampon into the vagina,
collect analysis using a catheter.

DETAILS: How to take a urological smear in men

Each of the methods is absolutely harmless during pregnancy and does not cause any side effects or inconveniences.

It is correct for pregnant women to take a urine test with a catheter, which is due to the complete hygiene of the collected material. This way, taking a sample is guaranteed and is protected from various biological secretions from the vaginal mucosa and external female genitalia getting into the urine.

The method of collecting urine with a catheter is called catheterization in medicine. Manipulations should be performed correctly in a medical facility by specialized personnel, taking into account certain rules to avoid bladder infection:

carry out preliminary hygiene of the genital organs,
take a lying position with your legs spread apart,
the health worker places a tray between the legs,
with the left hand (in sterile gloves) the labia are parted, and with the right hand the organs and the urine outlet are treated with a swab dipped in a weak solution of furatsilin,
the catheter is treated with glycerin or sterile petroleum jelly,
The catheter is inserted into the woman's urinary canal using tweezers.

Next, the first portion of urine is released, the second is collected for analysis, and then the remainder is emitted. Taking fluid with a catheter, in addition to the complete sterility of the tests, is very convenient in the last months of pregnancy, when it is quite difficult to perform thorough organ hygiene on your own.

Collection of material can be done with a disposable catheter, when it is inserted during urine collection. You can also use a temporary catheter during pregnancy, which is installed in a medical institution with special indications from a doctor, taking into account age, illness, pregnancy history and other nuances.

Risks and complications of bladder catheterization

If the nurse has practical skills, serious complications rarely arise. To exclude them, catheterization is performed without anesthesia, which allows you to immediately identify pain and obstacles in the urethral canal. In rare cases, after catheterization there are complaints of difficulty urinating and blood in the urine.

Possible complications during urinary catheterization:

damage to the urethral mucosa;
burning when urinating;
infection of the bladder and ducts;
false urge to go to the toilet.

Undesirable consequences of catheterization are more common in men, which is due to the structural features of their genitourinary system. To identify and eliminate complications, patients remain under medical supervision for some time.

The length of time the patient spends in the hospital depends on the purpose and method of catheterization.

Urine analysis during pregnancy

How to take a urine test correctly?

It is no exaggeration to say that being pregnant is a whole science. The expectant mother is often required to have such practical knowledge and skills that she had no idea about before. But our section “Workshop for the expectant mother” will help you master them easily and quickly.

An important part of medical monitoring of a pregnant woman is the regular conduct of various tests, including urine tests, which allow the obstetrician-gynecologist to promptly identify pregnancy complications, kidney pathology and other health problems in the expectant mother. But the analysis can only be informative if the woman has properly prepared for it.

Urine tests can be divided into routine tests and those performed when pathology is detected. The first includes a general urine test, which is included in the standard examination plan for all women with a normal pregnancy; the second includes tests according to Nechiporenko and Zimnitsky, determination of sugar in the urine, determination of diuresis - the daily amount of urine, determination of 17-ketosteroids, etc. Let's talk about each of them in more detail.

A general, or clinical, analysis allows you to determine the physical properties of urine (volume, color, smell, density, reaction), chemical components (protein, glucose, ketone bodies). Specialists also examine urinary sediment under a microscope - formed elements: red blood cells, leukocytes, epithelial cells, casts. If the pregnancy proceeds without complications, the doctor prescribes a test before the next consultation visit, i.e. once every 3-4 weeks in the first trimester, once

How to live with a permanent catheter

An indwelling catheter in the bladder increases the risk of infectious complications. To prevent them, the patient must constantly drink plenty of fluids. Due to this, the concentration of nutrients in urine decreases, which prevents the proliferation of bacteria.

Cleaning the catheter and caring for it:

the patient is placed on his back, an oilcloth diaper is placed under the buttocks;
the drainage fluid is drained, after which the catheter is removed;
the urinal is emptied, washed with water, disinfected with Dioxidin, Furacilin or Miramistin;
a syringe with 50-100 ml of antiseptic is inserted into one end of the drainage tube;
the urinal is emptied at least 5-6 times a day;
antiseptic treatment of the tube is performed up to 2 times a day.

After hygiene measures, the probe is washed with an isotonic sodium chloride solution. During sleep, the urine bag is secured to the bed so that it is below the urine bag.

How to change the device yourself

Replacing the drainage tube yourself is almost impossible. If necessary, catheterization is performed by close relatives after instructions.

Features of the procedure:

the urinal is emptied;
wash hands with soap and put on sterile gloves;
the catheter and genitals are wiped with an antiseptic;
a syringe is attached to the outer edge of the catheter to pump out liquid from a balloon at the other end of the tube;
With careful smooth movements, the drainage tube is removed from the urinary tract;
one end of the new catheter is treated with Vaseline and inserted into the bladder.

Urologists do not advise performing the procedure yourself unless absolutely necessary.
This is associated with the risk of damage to the urethra. Bladder catheterization is a urological procedure that allows urine to be drained from the bladder. It is done for diagnostic or therapeutic purposes for pathologies of the urinary system. If performed correctly, it prevents complications - hydronephrosis, uretic diverticulum, pyelonephritis.
