Objective: To describe surgical technique for single port robotic surgery using the da Vinci SP system and report the perioperative outcomes. Patients and methods: Between Jan 2019 and Jan 2021, single-port robotic urologic surgeries were performed in 120 patients by a single surgeon. Clinicopathologic data and perioperative outcomes were collected. All surgical procedures were performed with a transperitoneal approach through an umbilical single port. Additional assistant port was used in complex procedures for malignant disease. Surgeries were carried out using both above and below camera position for effective retraction. For reconstructive surgery using intestine, an extra-intracorporeal hybrid method was used. Surgical procedures involving both kidney and pelvis were performed without change of patient position or trocar placement. Results: Mean age was 62.7 years and 102 patients were male. For oncologic indication, 105 patients underwent surgeries including 66 radical prostatectomy, 25 partial nephrectomy, six radical nephrectomies, five nephroureterectomy and three radical cystectomy with urinary diversion. Fifteen cases with benign indication included four ureterolithotomy, seven uretero/pyeloplasty, three ureteroneocystostomy, and one ileal ureter reconstruction. All surgeries were performed successfully without conversion to other surgical approach. Clavien-Dindo grade III complication occurred in two patients. Conclusions: The da Vinci SP system provides a new robotic surgical platform for single port surgery while maintaining the major features of robotic surgery similar to multi-port surgery. Various single port urologic surgeries can be safely performed with this platform. © 2022 Asian Surgical Association and Taiwan Robotic Surgery Association
