Intravesical prostatic protrusion (IPP) has been reported to correlate with dysuria due to benign prostatic hyperplasia. Therefore, in this study, we aimed to assess the potential of IPP as a predictor of the occurrence of postoperative SUI and OAB. METHODS In total, 101 patients who underwent RARP between January 2013 and May 2016 and were available for at least a 12-month follow-up postoperatively and had been subjected to preoperative magnetic resonance imaging (MRI) were enrolled in this study. IPP was measured in the sagittal and horizontal views of MRI. Postoperative SUI and OAB were assessed using the 1-hour pad test and the OAB Symptom Score (OABSS) for each condition. Patients were divided into 3 groups: a control group, in which OAB was not observed either pre- or postoperatively; a de novo group, in which OAB occurred postoperatively; and an OAB group, in which symptoms of OAB were present preoperatively. RESULTS In cases with postoperative SUI, IPP was positively correlated with pad weight one month after RARP. In the OAB assessment, the control group consisted of 16 patients, and the de novo and OAB groups consisted of 58 and 27 patients each. The OAB group had a significantly larger IPP compared to the other two groups (control group, 1.78±2.73 mm; OAB group, 4.86±5.43 mm; de novo group; 2.45±2.86, p<0.05). Moreover, in the de novo group, the IPP showed a tendency to be greater in 33 patients whose OAB improved during the 12 months following surgery as compared to those patients who showed no improvement. CONCLUSIONS The IPP was positively correlated with the incidence of SUI and the presence of OAB before and after RARP. This result suggests that IPP may be considered a potential predictor of postoperative voiding status. © 2018FiguresReferencesRelatedDetails Volume 199Issue 4SApril 2018Page: e201-e202 Advertisement Copyright & Permissions© 2018MetricsAuthor Information Takashi Hamakawa More articles by this author Yasue Kubota More articles by this author Yuya Ota More articles by this author Taku Naiki More articles by this author Shuzo Hamamoto More articles by this author Ryosuke Ando More articles by this author Atsushi Okada More articles by this author Noriyasu Kawai More articles by this author Keiichi Tozawa More articles by this author Takahiro Yasui More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
