Filter by:After semirigid or flexible ureteroscopy operations where a DJ stent was placed, there is diversity in practice of placing a urethral catheter. The presence of vesico-ureteral reflux due to DJ stents has been proven to exist and can cause flank pain and UTI due to retrograde urine flow. The main purpose to place a urethral catheter is to keep a low-pressure bladder in order to prevent reflux alongside the DJ stent. However, this practice doesn't have an evidence-based support on the literature and some surgeons also advice patients to void frequently in the early postoperative period to avoid these aforementioned complications. The purpose of this study is to compare the 2 different approaches after ureteroscopy and DJ stent placement by evaluating the patient-reported outcomes along with laboratory tests.
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.
The purpose of this study is to investigate to forces needed to passage the ureteroscope up and down the ureter with and without a safety guidewire in place.
