OBJECTIVE To investigate the association between benign prostatic hyperplasia (BPH) patterns, classified by magnetic resonance imaging (MRI), with lower urinary tract symptoms (LUTS) or continence, preoperatively and after robot-assisted laparoscopic radical prostatectomy (RARP). MATERIALS AND METHODS This retrospective study included 49 prostate cancer patients, with prostate size >47 cm(3), who underwent an endorectal MRI followed by RARP. Five BPH patterns were identified according to Wasserman, and additional prostate measurements were recorded. LUTS were assessed using the International Prostate Symptom Score and the PR25-LUTS-Questionnaire score. Continence was assessed using the International Consultation of Incontinence Questionnaire-Short Form. RESULTS BPH pattern 3 (44.9%) was identified most common, followed by pattern 5 (26.6%), 1 (24.5%), and 2 and 4 (both 2%). BPH patterns were significant predictors of preoperative LUTS, with pedunculated with bilateral transition zone (TZ) and retrourethral enlargement (pattern 5) causing more severe symptoms compared with bilateral TZ and retrourethral enlargement (pattern 3) and bilateral TZ enlargement (pattern 1), whereas pattern 3 was additionally associated with more voiding symptoms compared with pattern 1. None of the BPH patterns was predictive of postoperative LUTS and continence. Independent predictors of continence at 12 months were lower preoperative PR25-LUTS score (P = .022) and longer membranous urethral length (P = .025). CONCLUSION MRI is useful for classifying patients in BPH patterns which are strongly associated with preoperative LUTS. However, BPH patterns did not predict remnant LUTS or postoperative incontinence. Postoperative continence status was only associated with preoperative LUTS and membranous urethra length.
