What are the indications for ureteral stenting?
Common indications include presence of urinary tract calculi and benign ureteral strictures. Ureteral stenting is also indicated in patients with extrinsic ureteral obstruction, ureteral trauma, and retroperitoneal fibrosis. In the setting of malignant ureteral obstruction, stenting may be performed if the patient does not have bladder outlet obstruction. Stenting allows the affected kidney to drain, and the patient is able to void. The most commonly used ureteral stents are the double-J stent and nephroureteral stent.
