Robot-assisted radical prostatectomy in patients with a history of endoscopic treatment for benign hyperplasia of the prostate

Aim: The purpose of this study was to determine whether previous prostate surgery has an adverse effect on the perioperative, histopathological and functional outcomes of robot-assisted radical prostatectomy (RARP). Patients and Methods: We retrospectively identified 42 patients (Group 1) who had a history of endoscopic prostate surgery for the treatment of benign prostate hyperplasia (BPH). We performed one-to-one matching based upon ten variables (age, BMI, PSA, SHIM, AUA-SS, c stage, biopsy Gleason score, median lobe presence, pathological stage and the extent of nervesparing) using a propensity score matching algorithm to generate a control group (Group 2). The perioperative, histopathological and functional outcomes were compared between these groups. All the patients were evaluated for continence outcomes, while only those patients who had a preoperative SHIM score of 17 and had a nerve-sparing surgery (unilateral, bilateral or partial) were examined for potency outcomes. Results: The patient demographics after matching are listed in Table I. The perioperative histopathological and functional outcomes were evaluated. There was no statistically significant difference at any point in time for either continence or potency outcomes Conclusion: RARP is a safe and effective procedure in patients who have a history of endoscopic prostate surgery. Although the OR time is higher in these patients, the PSM rates, complications, histopathological and functional outcomes are comparable to those of patients who have no prior prostate surgery.
