ABSTRACT
PURPOSE: Prostate volume(PV) has been known to be poorly correlated with other clinical parameters used to assess benign prostate hyperplasia (BPH), including international prostate symptom score(IPSS), peak flow rate(Qmax) and amount of postvoid residuals(PVR). The purpose of this study was to determine if the parameters of prostate volume including PV, transition volume, transitional zone index (TZI) and residual prostatic volume ratio(RPVR) correlated well with other clinical parameters before and after transurethral resection of prostate(TURP). MATERIALS AND METHODS: 31 men with symptomatic BPH were evaluated using IPSS, Qmax before and after TURP and the parameters of prostate volume were determined by transrectal ultrasonography(TRUS). The clinical outcome was evaluated by the difference(Delta) in IPSS, Qmean and Qmax before and 3 months after TURP. RESULTS: PV was not correlated with DeltaIPSS and DeltaQmax, but transition volume(r=0.394, p=0.034) and TZI(r=0.368, p=0.049) were significantly correlated with DeltaQmax. There were negative correlations between the RPVR and DeltaIPSS and DeltaQmax(r=-0.449, -0.385, p=0.011, 0.033). CONCLUSIONS: TRUS is a useful tool for estimating prostate weight before surgery of BPH. Transition volume, TZI and RPVR could be useful parameters to predict the IPSS and Qmax after TURP based with IPSS and Qmax before TURP. The smaller the RPVR after TURP, the better the clinical outcome.
