ABSTRACT
We performed a retrospective, case-control study to evaluate whether the urine flow acceleration (UFA, mL/s(2)) is superior to maximum uroflow (Qmax, mL/s) in diagnosing bladder outlet obstruction (BOO) in patients with benign prostatic hyperplasia (BPH). In this study, a total of 50 men with BPH (age 58±12.5 years) and 50 controls (age 59±13.0 years) were included. A pressure-flow study was used to determine the presence of BOO according to the recommendations of Incontinence Control Society (ICS). The results showed that the UFA and Qmax in BPH group were much lower than those in the control group [(2.05±0.85) vs. (4.60±1.25) mL/s(2) and (8.50±1.05) vs. (13.00±3.35) mL/s] (P<0.001). According to the criteria (UFA<2.05 mL/s(2), Qmax<10 mL/s), the sensitivity and specificity of UFA vs. Qmax in diagnosing BOO were 88%, 75% vs. 81%, 63%. UFA vs. Omax, when compared with the results of P-Q chart (the kappa values in corresponding analysis), was 0.55 vs. 0.35. The prostate volume, post void residual and detrusor pressure at Qmax between the two groups were 28.6±9.8 vs. 24.2±7.6 mL, 60.4±1.4 vs. 21.3±2.5 mL and 56.6±8.3 vs. 21.7±6.1 cmH2O, respectively (P<0.05). It was concluded that the UFA is a useful urodynamic parameter, and is superior to Qmax in diagnosing BOO in patients with BPH.
