Robotic-assisted retroperitoneal lymph node dissection for stage II testicular cancer

Objective: To evaluate the perioperative as well as early oncological outcomes of patients undergoing robotic retroperitoneal lymph node dissection for treatment of testicular cancer. Methods: We conducted a prospective consecutive case series of patients undergoing robotic assisted retroperitoneal lymph node dissection for metastatic testicular cancer between May 2018 and July 2021 at our institution. Data were collected on patient and tumour characteristics, intraoperative and postoperative parameters, and functional and oncological outcomes. Descriptive statistics are presented. Results: Nineteen patients were identified; 18 (94.7%) completed the procedure robotically and one was converted to open surgery; 78.9% of patients had stage >IIB and 12 (63.2%) patients had undergone prior chemotherapy. The median operative time was 300 (interquartile range [IQR] 240-315) min. Median blood loss was 100 (IQR 50-175) mL. Median length of stay was 2 (range 1-11) days. All robotically completed patients commenced diet and passed flatus on Day 1 and were discharged by Day 3. The median lymph node yield was 40.5 (IQR 38-51) nodes. All patients undergoing nerve -sparing procedures recovered antegrade ejaculatory function. One patient had a Clavien-Dindo III complication (chylous ascites requiring drainage). At a median follow-up of 22.3 (IQR 16.3-24.9) months, one patient developed retroperitoneal recurrence, which was successfully treated with second -line chemotherapy; no other patients have had recurrences. Conclusion: Robotic retroperitoneal lymph node dissection is a safe and feasible alternative to open surgery in appropriately selected patients, offering low morbidity. Early oncological outcomes are promising. Larger cohorts and longer follow-ups are required to validate our institution's findings. (c) 2024 Editorial Office of Asian Journal of Urology.
