Feasibility and safety of a non-indwelling urinary catheter after flexible ureteroscopy with intelligent control of renal pelvis pressure: A retrospective study

Abstract

Background To explore the feasibility and safety of a non-indwelling urinary catheter after flexible ureteroscopy with intelligent control of renal pelvic pressure (FUS-ICP). Methods In this retrospective study, we assessed patients with upper urinary tract stones who were treated with FUS-ICP at the Ganzhou People's Hospital from February 2022 to December 2023. Patients were divided into the non-urinary catheter (non-UC) and urinary catheter (UC) groups according to whether an indwelling catheter was used after surgery. Results In total, 142 patients were included in the study. There was no significant difference in the preoperative general data between the two groups. Patients in the non-UC group performed better than those in the UC group in terms of catheter-related bladder irritation (P = 0.001), the Sedation-Agitation Scale score (P = 0.012), and the numerical rating scale (P = 0.003). The incidences of urinary retention (P = 0.620), urinary tract infection (P = 0.529), and re-indwelling urinary catheters (P = 0.438) in the UC group were inferior to those in the non-UC group, but there was no statistical significance. Conclusions Non-indwelling urinary catheters are safe and feasible for patients undergoing FUS-ICP.
