Abstract:
Objective To investigate the correlation between prostatitis and bladder outlet obstruction (BOO) in patients with benign prostatic hyperplasia.Methods From January 2008 to January 2012,Three hundred BPH patients were divided into two group according to whether had prostatitis determined by pathology.One hundred and thirty six patients with simple BPH and 164 patients with BPH combined with prostatitis were included with the median age of 69 years.PSA was (4.9 ± 8.3) μg/L and (7.0 ± 8.5)μg/L,the prostate volume was (41.4±18.1) ml and (48.7±20.7) ml,and IPSS was 21.9±7.0 and 27.5 ± 5.1 in BPH group and prostatitis group,respectively.The urodynamic parameters of bladder outlet obstruction between the two groups were analyzed.Results Qmax was (8.8 ± 4.8) ml/s and (6.3 ± 3.7)ml/s,Pdet.Qmax was (96.7 ± 33.0) cm H2O and (113.3 ± 39.8) cm H2O,AG value was 77.7 ± 31.9 and 93.9 ± 39.6,and Schafer grading value was 3.3 ± 1.5 and 4.4 ± 1.2 in BPH group and BPH combined with prostatitis group,respectively (P ＜ 0.05).Logistic regression analysis showed that prostatitis (OR =2.66,P =0.002),PV (OR =1.37,P =0.000),and Qmax(OR =0.72,P =0.000) were positively correlated with Schafer grading value.Conclusions Prostatitis increased the degree of BOO in patients with BPH.
