Abstract

AbstractTo evaluate factors affecting the outcomes of short-term Mono-J insertion for 6 h following ureteroscopic stone removal. Patients treated with a Mono-J for 6 h after ureterorenoscopy and stone removal were analysed. FaST 1 and 2 (Fast Track Stent Studies), two consecutive single academic centre studies, were conducted between August 2014 and April 2018. In each study, we randomized patients with renal or ureteral calculi to two groups before ureterorenoscopy. FaST 1 compared a Mono-J insertion for 6 h versus Double-J insertion for 3–5 days after ureterorenoscopy. FaST 2 compared a Mono-J insertion to a tubeless procedure in the same clinical setting. All patients were pre-stented for 3–5 days before URS. The study endpoint was stent-related symptoms as assessed by a validated questionnaire (USSQ). Results were stratified by clinical parameters, stone characteristics and operation details. 108 of 156 initially randomized patients undergoing ureterorenoscopy were included. USSQ scores covering the time 3–5 weeks after stone removal showed a significantly reduced urinary symptoms and pain index compared to the scores before ureterorenoscopy. USSQ results before and after stone removal did not correlate with stone size or operation time and did not differ significantly depending on stone localization, the treating endourologist, or ureterorenoscopic device used (p > 0.05). Six patients (5%) required reintervention. Following secondary ureterorenoscopy and ureteral drainage with a Mono-J for 6 h, quality of life is independent of stone size and localization, operation time, the treating endourologist, and the URS device used.
