OBJECTIVE: To evaluate the feasibility and preliminary outcomes of prone retroperitoneal robotic-assisted laparoscopic pyeloplasty (prRALP) for ureteropelvic junction obstruction (UPJO), an innovative approach designed to optimize surgical exposure and suturing.
METHODS: This retrospective cohort study analyzed four patients who underwent prRALP between September 2023 and May 2024. The surgical technique involved prone positioning and multi-port robotic access, enabling direct posterior exposure of the renal pelvis and proximal ureter. Primary outcomes included operation time (OT), estimated blood loss (EBL), complications (Clavien-Dindo classification), and postoperative renal function (eGFR). Success was defined by radiographic resolution of obstruction, symptom relief, and no need for reintervention.
RESULTS: All procedures were completed robotically without open conversion and reoperation. Mean OT was 64.6 ± 14.4 min, with minimal blood loss of 27.5 ± 15.0 mL and no transfusions. The mean postoperative hospital stay was 3.3 ± 0.5 days. One minor complication (fever, Clavien 1) occurred (25%). Postoperative eGFR improved by 1.3 ± 14.2 mL/min/1.73 m2 at 90-day follow-up, with all patients achieving obstruction-free recovery and a mean eGFR of 87.2 ± 69.8 mL/min/1.73 m2 being maintained at 1-year postoperatively.
CONCLUSION: prRALP demonstrates feasibility and safety, leveraging prone position to enhance retroperitoneal access and suturing precision. Larger prospective studies are warranted to validate its technical benefits and reproducibility.
