Technical feasibility of robot-assisted laparoscopic radical prostatectomy in renal transplant recipients: Results of a series of 12 consecutive cases

Introduction: We evaluate the technical feasibility of robotic prostatectomy in renal transplant recipients. Methods: We retrospectively analyzed preoperative and perioperative settings, as well as functional and oncologic results of 12 patients operated on between 2009 and 2013. Prostatectomy was performed via a transperitoneal approach without any changing in the ports position. The average age was 61.92 ± 2.98 years. The period between transplant and the diagnosis of adenocarcinoma was 79.7 months. The mean PSA was 7.34 ng/mL (range: 4.9–11). Results: The operative time was 241.3 ± 35.6 minutes with only one conversion and one transfusion. The intervention was difficult due to adhesions on the side of the graft in 50% of cases. There was a case of obstructive acute renal failure resulting from a hematoma of the Retzius treated by percutaneous nephrostomy at D20. There was a majority of pT2c (72.7%), including 3 positive margins (27.3%) and 2 biochemical relapses treated with radiotherapy and hormonotherapy, respectively. The end point prostate-specific antigen was undetectable. There was no significant difference between preoperative and J7 creatinine (p = 0. 22). Conclusions: Robotic prostatectomy in renal transplant recipients is a safe technique with no serious effects on the allograft.
