Abstract

Introduction and Objective: Single port (SP) robotic surgery has emerged as a feasible alternative to conventional multiport robotic surgery for a variety of urologic procedures. SP facilitates the use of a retroperitoneal approach, especially when targeting pathology near the kidney or ureteropelvic junction (UPJ). Here we present a large, longitudinal, multi-institutional cohort of patients undergoing SP robot-assisted pyeloplasty (RAP). Methods: Using an IRB-approved, prospective database across five institutions, we collected patients undergoing SP RAP from October 2018 to August 2024. Demographics, perioperative and postoperative data are reported with descriptive statistics in Table 1. Results: 128 patients underwent SP RAP. 36 (28.1%) had a prior history of abdominal surgery. The majority of cases (70.3%) used pure SP, with the accessory port added only twice after 2023. 76 (59%) patients underwent an intraperitoneal RAP and 18 (14%) underwent an extraperitoneal approach. Median blood loss was 20 mL, with no requirement for transfusions. Median time to catheter removal was 1 day (0.5-1). There were no intraoperative complications. The majority of hospital stay complications were Grade I (50%). The majority of 30-day complications were Grade I or II (42.8%). The two Grade III complications included retroperitoneal hematoma and urine leak. Conclusions: We present the, to our knowledge, largest multi-institutional cohort of patients undergoing SP RAP. SP RAP provides a safe and feasible option for treatment of UPJ obstruction.
