METHODS After IRB approval, we prospectively enrolled patients who were candidates to surgical treatment of BPH. Inclusion criteria comprised men >50 years old; International Prostate Symptoms Score (IPSS) ¡Ý19 refractory to medical treatment; and bladder outlet obstruction confirmed by urodynamic examination. Analyzed data comprised MRI parameters: prostate volume, intravesical prostatic protrusion (IPP), prostatic urethra length (PUL; from Verumontanum to bladder neck), posterior urethra inclination angle (one leg in the prostatic urethra, another in the horizontal plane ¨C PUIA; figure 1); urodynamic parameters: bladder outlet obstruction index (BOOI), Schaefer index. Regression and Receiver-Operating Curve analysis was performed to evaluate the association between MRI findings and BOOI and severe Schaefer index (5 and 6). The level of significance was set at p<0.05. RESULTS Between Jan/11 and Jan/13, 55 patients were included. Of those, 3 had incomplete urodynamic evaluation and were excluded. On logistic regression, IPP, PUL and PUIA were significantly associated with Schaefer 5 and 6 (table 1). The only factor to significantly impact BOOI was PUIA. PUIA had the highest area under the curve to predict severe Schaefer on ROC analysis (AUC=0.795; p=0.01). PUIA of 32 provided the best cutoff value, with sensitivity of 76.5%, specificity of 78.6%, positive predictive value of 59% and negative predictive value of 89%. CONCLUSIONS MRI parameters may predict the grade of bladder outlet obstruction from urodynamic evaluation. PUIA had the best sensitivity and specificity to predict severe obstruction. © 2014FiguresReferencesRelatedDetails Volume 191Issue 4SApril 2014Page: e67 Advertisement Copyright & Permissions© 2014Metrics Author Information Eduardo Muracca Yoshinaga More articles by this author Elcio Nakano More articles by this author Giovanni S.
