Sponsor's own description

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.
