Ureteral stricture (narrowing of the ureter) ; Definition, Causes, symptoms, treatment

A ureteral stricture refers to the narrowing of the ureter, which can obstruct the flow of urine from the kidneys to the bladder. This condition can result from various causes, including: Intrinsic factors: Kidney stones, infections (e.g., tuberculosis), or tumors within the ureter. Extrinsic factors: Compression by nearby masses or diseases. Iatrogenic causes: Injuries during surgeries, radiation therapy, or medical procedures. Congenital anomalies: Structural abnormalities present from birth. Symptoms may include flank pain, fever, hematuria (blood in urine), or recurrent urinary tract infections. Diagnosis typically involves imaging techniques like ultrasound, CT scans, or retrograde pyelography, and sometimes endoscopic evaluation. Treatment options vary based on the severity and cause of the stricture. They may include: Ureteral stenting: To temporarily relieve obstruction. Balloon dilation: To widen the narrowed segment. Endoscopic ureterotomy: Surgical incision of the stricture. Open or laparoscopic surgery: For longer or complex strictures. #stricture
