Renal and Urinary System Ultrasound

The urinary system is a system consisting of both kidneys, two urinary ducts from both kidneys to the bladder, the bladder and the duct for expelling urine from the bladder. Kidney stones and urinary tract infections are the most common diseases of this system. Kidney stones may remain in the kidney as well as fall into the urinary canal. If the stone falls into the urinary canal, it can cause obstruction and infection, causing serious pain. Patients present with sudden-onset flank pain. In this case, ultrasound examination is the first choice to evaluate the stone, the location of the stone, the obstruction in the kidney and urinary tract, and the signs of infection.

Tumoral masses that develop from the kidney and bladder can be easily detected by ultrasound and color Doppler ultrasound. Color Doppler examination can be helpful in terms of diagnosis by looking at the blood supply of the possible mass. In these cases, biopsy of kidney masses can be performed under ultrasound guidance.

Another important organ of this system is the prostate. The prostate is a circular organ located in the lowest part of the bladder in men, around the outlet duct. They usually grow with age. This growth is determined by calculating the volume with ultrasound. Masses developing from the prostate can be detected by looking through the anterior abdominal wall or by entering through the anus with an endocavitary probe.

Enlargement of the kidney canals can be detected in babies in the womb and in the newborn period. In this case, the duct enlargement of the baby is checked at regular intervals. If it progresses too much, it can be surgically intervened. The most common causes of this condition are vesicoureteral reflux and posturethral valve.

One of the most common causes that can be detected in patients with hypertension is narrowing or irregularities in the renal vessels. This condition is easily detected by renal color Doppler examination and treatment can be planned.

In patients with severe obstruction and enlargement in the kidney and urinary tract for any reason, a catheter is placed into the kidney with a procedure called percutaneous nephrostomy under ultrasound guidance, in order not to impair kidney functions, and urine drainage can be performed through this catheter.
