A ureteral stricture can block or narrow the ureter, making it difficult to pass urine from the affected kidney. To help open the passage and prevent it from narrowing, ������� Langone physicians can perform stenting.

In this procedure, doctors place a small, hollow plastic or metal device called a stent into the ureter. This allows urine to flow through the ureter more easily.

A stent is inserted during a short, outpatient procedure that requires sedation or regional anesthesia. Lifelong maintenance is required—stents need to be replaced every six months to year. Stenting is typically a temporary treatment that is used in people who cannot have surgery to reconstruct the ureter.

Whenever possible, ������� Langone doctors prefer to correct the ureteral stricture using surgery, preventing the need to maintain a stent.
