METHODS: Patients who underwent RARP between October 2010 and July 2014 were included in the present study. Age, body mass index (BMI), prostate-specific antigen (PSA) were recorded. All patients underwent pressure-flow studies (PFS) before RARP. Prostate volume (PV), IPP length, length (MUL) and width (MUW) of the membranous urethra and levator thickness were measured using T2-weighted magnetic resonance imaging (MRI). Binary logistic regression analysis was performed to evaluate associations between postoperative urinary incontinence (PUI) and preoperative factors, including PFS results and MRI. To evaluate the effects of IPP, patients were categorized into two groups based on IPP length: Group 1, < 5 mm, and Group 2, ≧5 mm. The International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS), Quality of Life (QOL) index, and number of pads used were evaluated 1, 3, 6, and 12 months after RARP in the two groups. RESULTS: A total of 119 patients were eligible for this study. Multivariate logistic regression analyses showed that MUL, NS and IPP were significantly associated with continence at one month post-RARP, and only NS was significantly associated with continence 12 months post-RARP. The rate of achieving zero-pad was significantly different between two groups at one month post-RARP, but after 3 months, there was no significant difference. CONCLUSIONS: The present data suggest that IPP affects early PUI. IPP is strongly associated with preoperative voiding symptom, but it does not predict lower urinary tract symptom or long term PUI.
