Asymptomatic bacteriuria prior to partial and radical nephrectomy: To screen or not to screen? Results from the national and multicenter TOCUS database.

INTRODUCTION: In the era of increased bacterial resistance, the main strategy is to reduce the prescription of antibiotics when possible. Nowadays, it is highly recommended to screen for asymptomatic bacteriuria (ABU), prior to urological surgery with potential mucosal breach or urine exposure. Screening and treating urinary colonization is a strategy widely adopted before radical and partial nephrectomy but without any evidence. Our main end point in this study is to analyze the relationship between preoperative urine culture and the risk of postoperative febrile urinary tract infection (UTI) or surgical-site infection (SSI) in partial or radical nephrectomy patients. METHODS: We conducted a multicenter retrospective cohort study between January 2016 and January 2023 in 11 French tertiary referral hospitals (TOCUS database). We collected the data for 269 patients including several pre-, intra-, and post-operative variables that could potentially increase the risk of postoperative UTI and SSI including preoperative urinary culture results. RESULTS: The incidence rate of postoperative UTI and SSI was 8.9% in our study. After conducting a logistic multivariate analysis, a propensity score matching analysis, and a subgroup analysis, we found no significant correlation between the urine culture and the postoperative UTI risk [OR = 1.2 (0.5-2.7) (p = 0.7)]. Only the postoperative non-infectious complications were related to a higher risk of postoperative UTI [OR = 12 (4-37), p < 0.001)]. CONCLUSION: Our research shows that screening and treating for ABU prior to radical or partial nephrectomy seems to be unnecessary to prevent postoperative UTI and SSI.

Robot-assisted Radical Prostatectomy with the Dexter Robotic System: Initial Experience and Insights into On-demand Robotics.

We report the world's first case series of ten robot-assisted radical prostatectomy (RARP) procedures performed with the Dexter robotic system (Distalmotion SA, Épalinges, Switzerland). The Dexter system is an open robotic platform that integrates into the existing operating room (OR) equipment. The optional sterile environment for the surgeon console provides flexibility for transition between a robot-assisted surgical procedure and a traditional laparoscopic setup, allowing surgeons to selectively use their preferred laparoscopic devices for specific surgical maneuvers on-demand. Ten patients underwent RARP ± lymph node dissection at Saintes Hospital (Saintes, France). Positioning and docking of the system were quickly mastered by the OR team. All procedures were successfully completed, without any intraprocedural complication, conversion to open surgery, or major technical failure. The median operative time was 230 min (interquartile range [IQR] 226-235), and the median length of stay was 3 d (IQR 3-4). This case series demonstrates the safety and feasibility of RARP with the Dexter system and provides the first insights into what an on-demand robotics platform could offer to hospitals willing to start or expand their robotic surgery program.
