Evaluation of Stent-Related Symptoms After ComfiJ Ureteric Stent Versus Conventional Double-J Ureteric Stent: A Prospective Multicenter Randomized Controlled Trial
This prospective multicenter randomized controlled trial will compare stent-related symptoms after placement of a ComfiJ ureteral stent versus a conventional double-J ureteral stent in adult patients undergoing unilateral ureteroscopy or retrograde intrarenal surgery for urinary stones when short-term postoperative ureteral stenting is clinically indicated. Eligible patients will be randomized intraoperatively after the operating surgeon confirms the need for postoperative stenting. The primary outcome will be the Ureteral Stent Symptom Questionnaire urinary symptoms domain score on postoperative day 14 before planned stent removal.
• Age 18 to 80 years.
• Adult patients undergoing unilateral ureteroscopy or retrograde intrarenal surgery for ureteric or renal stones.
• Intraoperative confirmation that short-term postoperative ureteric stenting for approximately 2 weeks is clinically indicated.
• Indications for postoperative stenting may include ureteric edema, minor ureteric mucosal trauma, need for ureteric dilatation, ureteral access sheath use with expected postoperative edema, impacted stone, residual dust or fragments requiring temporary drainage, or prolonged procedure.
• Ability to understand and complete the Arabic Ureteral Stent Symptom Questionnaire.
• Ability to provide written informed consent.
