ABSTRACT
Objective To study the relationship between the bladder outlet obstruction(BOO)and the area under the curve of detrusor during voiding related parameters. Methods One hundred and thirty-eight patiens with benign prostate hyperplasia(BPH) underwent clinical evaluation, including physical examination, flow rate and post-void residual volume measurement. Pressure flow studies were performed. Mean patient age was 68 years (range 56 to 82). The AG number and the LinPURR were recorded to classify the patients into 3 groups, namely unobstructed, equivocal obstructed and obstructed, as the traditional classification. Two new parameters including the area under the curve of detrusor pressure during voiding(AUCdet) and the area under the curve of detrusor pressure during voiding adjusted for voided volume(AUCdet/Vol) were calculated and compared with the traditional classification using the Linear discriminant analysis. Results According to the traditional classification, there were 33 unobstructed, 32 equivocal and 44 obstructed cases. The AUCdet and AUCder/Vol of the 3 groups were different(P<0.001). Linear discriminant analysis showed that of the cases, 90. 9%(30/33), 43.8%(14/32) and 70. 5%(31/44) were identically categorized by the traditional and the AUCdet/Vol classifications in the unobstructed, equivocal and obstructed groups, respectively. Conclusions The area under the curve of detrusor pressure during voiding related parameters appear to be good parameters of the BOO in patients with BPH. Further studies are needed to test the reliability and validity of these new parameters.
