A ureteric stricture is a narrowing of the ureter, the tube that carries urine from the kidney to the bladder. This condition can result from various causes, including previous surgeries, kidney stones, infections, or radiation therapy. Congenital defects or medical conditions such as fibrosis or tumors can also lead to strictures. The narrowing restricts urine flow, leading to potential complications like hydronephrosis, which is swelling of the kidney due to urine buildup. Identifying the underlying cause is crucial for effective treatment and preventing recurrence.

Patients with ureteric strictures may experience symptoms such as flank pain, recurrent urinary tract infections, hematuria (blood in the urine), and reduced urine output. In severe cases, there may be signs of kidney failure, including nausea, vomiting, and swelling in the legs and ankles. Diagnosis typically involves imaging studies such as ultrasound, CT scans, or MRI to visualise the ureter and identify the location and extent of the stricture. Additional tests like retrograde pyelography or ureteroscopy may be employed to provide a more detailed view. Early detection and appropriate management are essential to alleviate symptoms and preserve kidney function.
