The Role of Ureteral Stenting Following Uncomplicated Ureteroscopy for Ureteral and Renal Stones: A Randomized, Controlled Trial

It is well established that uncomplicated distal ureteroscopy can be safely performed without leaving a ureteral stent. However, many urologists continue to leave ureteral stents following uncomplicated ureteroscopy, regardless of stone location, due to concerns for post-operative complications, patient symptoms and to reduce unplanned medical visits. There is a paucity of data regarding the utility of stent placement for proximal ureteral or renal stones following ureteroscopy. We have designed a prospective, randomized controlled trial to evaluate the role of ureteral stent placement following ureteroscopy and pyeloscopy in proximal and renal stones.
