Urological ultrasound has long been one of the most common diagnosis of the body, all this thanks to the high information content, simplicity of procedures and affordability for all segments of the population. Using ultrasound to visualize and explore the possible nearly all body systems, including the identification of the problems associated with the urinary tract and prostate. According to the results of ultrasound urologist can evaluate the structure and function of the upper urinary tract (including kidney and ureter).
What allows you to define a study with ultrasound?
Modern ultrasonic devices enable diagnosis:
- renal (size and position)
- structure and a thickness of renal tissues (parenchyma)
- the size and structure of the renal pelvis and calyces
- ureter diameter
- renal blood flow.
Ultrasound also allows to diagnose the condition:
- bladder and urethra
With urological ultrasound determined by the number of bladder residual urine after urination and established the dependence of the diameter of the ureter from the fullness of bladder filling.
Urological ultrasound is widely used in diseases of the genitourinary system. With it, the doctor-diagnostician:
- defines congenital anomalies or trauma urinary system
- causes of violations of the urethral process
- diagnose tumors of the urinary system and carries out their prevention
- determines causes of neurogenic voiding.
- Ultrasound of the kidneys and the bladder is invaluable in the diagnosis of
- inflammatory diseases, kidney stones and urinary diversion violations.
Renal ultrasound study
Renal ultrasound is considered to be only the most informative method for in vivo study of kidney tissue and adjacent structures, including renal vascular Doppler method. kidney research procedure is painless and takes no more than half an hour. The kidneys can be well visualized without conducting pre-deployment training. Renal ultrasound passes using transabdominal transducer in several projections: from the abdomen, back, as well as the position of the patient lying on his side. In the study accurately identified the following diseases:
- kidney tumors
- cysts on the kidneys
- congenital anomalies.
Also, renal ultrasonography is appointed to assess the state of the kidneys after transplantation, renal colic, kidney injury, suspected violation of the outflow from the kidney. renal ultrasound is required for dynamic control of the patient during a stent or nephrostomy. Under US supervision is carried out taking punctures and drainage of the kidney in order to diagnose and treat.
Ultrasound of the bladder: transabdominal and transrectal
The purpose of this procedure in the evaluation of the size, volume, and the walls of the contours of the bladder, measuring residual urine volume after voiding.
Ultrasound of the bladder is indicated for:
- suspected bladder stones
- renal colic
- bladder injuries
- detection of blood in urine
- micturition disorders
- suspected tumor and cystic tumors in the bladder.
Also, ultrasound of the bladder is a means of control over the process of the treatment of pathologies of the ureters and bladder. Research and bladder ultrasound can be held in two ways: transabdominal and transrectal.
The procedure takes 15 minutes and is carried out in the supine (transabdominal) or side (transrectal). Transabdominal ultrasound is performed by a sensor through the anterior abdominal wall, on which the gel is applied to a dense sensor contact with the skin and facilitate its sliding.
For transrectal investigation (TRUS) uses a different sensor that is inserted through the anus into the rectum. For better visualization of bladder filling is required it. To do this for 3-4 hours before the procedure, you must refrain from urinating. If ultrasound bladder in women can be examined uterus and ovaries, and prostate in men. Examining the prostate gland, a specialist can detect adenoma or prostate cancer.
A study of the testes and scrotum
Holding ultrasound of the testicles and scrotum does not require special preparation. It is indicated for pain in the scrotum, its increase, bumps and seal. Ultrasound diagnosis helps to identify testicular torsion, cysts and tumors, causes of erectile dysfunction and infertility.
