Ultrasound examination (ultrasound) of the bladder

Ultrasound scan of the bladder is a highly effective method for diagnosing this organ. This study allows to evaluate the work and condition of the bladder.

The physician can determine the important parameters of the organ, namely: contour, thickness, volume and mass. A very important parameter is the determination of the amount of urine that remains in the bladder after it is completely empty.

Ultrasound examination of the bladder can be transabdominal (examination using an external sensor through the anterior abdominal wall), transrectal (the sensor is inserted into the rectum) and transvaginal (the sensor is inserted into the vagina).

If there are serious indications, then the scan can be performed several times in a row, while the ultrasonic waves do not affect the future state of the body.

What is the purpose of the ultrasound of the bladder?

Ultrasound of the bladder is carried out in order to timely or differential diagnosis of diseases of the urological tract, in which the process involves the bladder or other organs of the urinary system, as well as the prostate gland. These diseases include inflammatory changes, urodynamic disorders, urolithiasis and neoplasms.

In which cases, appoint an ultrasound scan of the bladder

In order to timely diagnose serious pathological processes, doctors recommend to undergo an ultrasound scan annually, even if the patient does not have serious indications for its conduct. With its help, you can prevent the occurrence of serious complications and apply conservative therapy or surgical treatment in time.

Thus, an ultrasound examination of the bladder is recommended for patients in the following cases:

  • suspected bladder disease;
  • blood in the urine;
  • frequent and uncontrolled urination;
  • urine retention;
  • signs of kidney, bladder and prostate diseases;
  • trauma to the urinary system;
  • deviations of laboratory parameters in the urine;
  • suspected urolithiasis.

Also, an ultrasound scan is carried out during the period of treatment of the patient, in order to assess the dynamics of the course of the disease from the therapy.

When is a bladder ultrasound examination contraindicated?

This diagnostic procedure has no contraindications, as it does not have negative effects on the body. It can and should be carried out by women during pregnancy and children of all ages.

How to prepare for a bladder ultrasound

In order to obtain reliable information and a complete picture of the state of the bladder, diagnosis is carried out only when it is filled.

To this end, doctors recommend an hour before the study to drink one liter of plain bottled water. Or wait until the bladder fills naturally without forcing. This will take at least three to four hours, so do not go to the toilet during this period. If the diagnosis will be carried out in the morning, you can not go to the toilet after sleep. But as a rule, it is very difficult. Therefore, you can set the alarm at 4 am and go to the toilet, and then refrain from urinating until the ultrasound scan.

The results of diagnostics can be adversely affected by increased gas formation, so if you suffer from such a problem, then a couple of days before the procedure, try to follow certain rules in the diet. Eliminate from the diet fresh vegetables, fruits, beans and drinks containing gases. Also refrain from carbonated and alcoholic beverages.

How is the bladder diagnosed using ultrasound?

Depending on the intended disease, ultrasound of the bladder can be done in three ways:

  • external - ultrasonic waves pass through the abdominal wall (there are difficulties in carrying out this technique for patients with excess weight);
  • vaginal - a special sensor is inserted into women through the vagina;
  • research through the rectum.

When conducting an external scan, the patient must strip to the waist or simply lift the clothes to free the abdominal area. Then he lies down on the couch. The doctor puts on the abdomen a special conductive gel, which will transmit the signals of the ultrasonic sensor. The gel is cold, so the patient may experience some discomfort, but this is not for long, under the influence of body temperature, the gel quickly heats up.

The doctor drives the sensor on the gel, thus begins scanning the bladder, as well as nearby organs and tissues. The resulting waves are displayed on the screen as an image.

The procedure is completely painless and lasts about twenty minutes.

Sometimes, to clarify the presence of pathological processes, the patient is asked to go to the toilet, after which the doctor re-scans and measures the bladder. As a rule, experts resort to this technique if there are suspicions of serious diseases, when it is not possible to fully diagnose because of the patient's extra weight or the presence of benign tumors, adhesions and free fluid in the peritoneum.

For serious indications, the doctor may prescribe a vaginal examination or rectal scan.
