Evaluating Surgical Outcomes of Robot Assisted Simple Prostatectomy in the Retreatment Setting.

To report perioperative and postoperative outcomes in men who undergo salvage RASP (sRASP) following some other endoscopic outlet procedure for benign prostate enlargement (BPE) compared to those undergoing RASP for primary treatment (pRASP). A prospectively maintained database consisting of all RASP surgeries (December 2014-October 2019) performed at our institution by 3 different urologists was used. Patients who had received an endoscopic procedure for BPE prior to their RASP (sRASP) were compared to those who had not had a prior outlet procedure (pRASP). In total, 310 men underwent RASP during the study period. Of those, 30 (9.7%) had undergone an endoscopic procedure prior to surgery. There were no significant differences in age, race, ASA, BMI, prostate volume, PSA or rates of preoperative retention (P> .05 for all). Men who were treatment-naive had significantly higher preoperative International Prostate Symptom Scores (IPSS) than men who had a prior procedure (18.3 ± 7.7 vs 13.6 ± 6.2, P = .008). However, there were no significant differences in functional or quality of life outcomes between the 2 groups (P > .05 for all). There were no significant differences in perioperative or post-operative outcomes between the 2 groups. Furthermore, rates of post-operative complications and incontinence were similar between groups (11% vs 10%, P = .9 and 2% vs 0%, P = 1 respectively). Performing a RASP after prior endoscopic procedure for BPE was found to be safe and effective. Success and complication rates were similar to patients with no prior procedures.
