Multicenter experience with robot-assisted radical prostatectomy in renal transplant recipients

To evaluate our multi-institutional outcome with robot-assisted radical prostatectomy (RARP) in renal transplant recipients and describe technical modifications of the procedure.

We retrospectively reviewed 1677 patients, 1422 from Mayo Clinic Arizona and 255 from Loyola University Medical Center, undergoing RARP from March 2004 to October 2010, of which 7 were renal transplant recipients. Baseline demographic features, perioperative data, and oncologic outcomes were reviewed.

At diagnosis, mean patient age was 63.3 years and serum prostate specific antigen was 6.17 ng/mL. The mean total operative time was 186 minutes (range, 80-210 minutes). No intraoperative complications were noted. The mean hospital length of stay was 1.8 days (range, 1-3 days). Clavien grade II postoperative complications occurred in 3 of the 7 patients (42.9%), consisting of urosepsis, atrial fibrillation, and gross hematuria, all resolving with appropriate medical management. No significant changes were observed in graft function. Two patients (28.6%) had positive surgical margins. During a mean follow-up of 16 months, 1 patient with pathologic T3a, Gleason 9 cancer experienced a biochemical recurrence, which was treated with salvage external-beam radiation and androgen-deprivation therapy.

Our series suggests that RARP is a safe and feasible form of therapy for localized prostate cancer in a select group of renal transplant recipients.
