Abstract:
Objective To investigate the diagnostic significance of presumed circle area retio(PCAR) measured by TRUS in detecting bladder outlet obstruction (BOO) from BPH. Methods 78 cases of BPH aged from 62～78 with IPSS 22.0?2.2 were studied from June of 2000 to June of 2001. Prostate volume, Transition zone index(TZI) and PCAR were measured with TRUS. Urodynamics were conducted, including Qmax, P det.Qmax and AG number. The correlation analysis was performed. Results TZI(0.48?0.15) and PCAR (0.72?0.10) were both closely related to AG number, P =0.028 and 0.008. The multiple regresion analysis showed that PCAR was 1.63 times more effective on AG number than that of TZI. AG number 40 was adopted as the cutoff point of BOO, and PCAR 0.75. The dignsotic correctivity has been more than 90%. Conclusions PCAR measured by TRUS is simple and reliable to detect BOO due to BPH.
