PURPOSE: Intravesical protrusion of the prostate (IPP) can affect voiding. We evaluated the improvement in lower urinary tract symptoms and patient satisfaction after laser prostate photovaporization in benign prostatic hyperplasia (BPH) patients with or without IPP. MATERIALS AND METHODS: This prospective study included 134 patients who underwent GreenLight HPS laser photoselective vaporization prostatectomy (PVP) between January 2010 and July 2011 patient. Preoperative IPP was evaluated by using the retroflexed view from flexible cystoscopy. evaluation included complete medical history, International Prostate Symptom Scores (IPSS), maximum flow rate (Qmax), postvoid residual (PVR), serum prostate-specific antigen (PSA), and transrectal ultrasonogram. Changes from baseline in Qmax, PVR, total IPSS, and IPSS subscores (voiding and storage) were analyzed at postoperative months 1, 3, and 6. RESULTS: The patients' mean age was 66.6±7.8 years. Mean serum PSA and prostate volume were 1.7±1.5 ng/mL and 42.9±16.7 g, respectively. No significant differences existed between the IPP and no IPP groups in preoperative prostate volume, total IPSS, PSA, or lasing time and energy. The mean follow-up duration was 6.2±1.9 months. IPP patients showed significant improvements in total IPSS and voiding subscores at months 1 and 3. Improvements in the quality of life score and storage subscore were not significantly different between the groups. Qmax was significantly improved at 6 months postoperatively in the IPP group versus the no IPP group. CONCLUSIONS: Among patients who underwent PVP for BPH, the IPP group showed more symptom improvement, especially in voiding symptoms, than did the no IPP group. Preoperative cystoscopy is helpful for evaluating IPP and for anticipating postoperative outcome.
