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/s2 and (8.50±1.05) vs. (13.00±3.35) mL/s] (P〈0.001). Accol;ding to the criteria (UFA〈2.05 mL/s2, 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 pros- tate 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 cmHzO, 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.展开更多

Patient and Methods: The study was conducted in Department of General Surgery in Maulana Azad Medical College, New Delhi. 60 men with proven clinical diagnosis of BPH of size 30 grams and less presenting with symptoms of bladder outlet obstruction (BOO) were randomised prospectively to undergo either of the two operative modalities. Preoperatively size of the prostate, symptom scoring (IPSS), peak flow rate (Qmax) were assessed. Postoperatively and during 4 months follow up the following data were collected—operative time, catheterisation period, hospital stay, blood loss, Qmax and IPSS. Results: Preoperative parameters in both the groups showed no statistically significant differences with respect to prostate size, Qmax and IPSS Scoring. At 4 months follow up Qmax increased from (6.35 ± 4.49) to (16.41 ± 2.28) in TURP group and (4.51 ± 3.57) to (15.95 ± 2.58) in BNI group. IPSS decreased from 18.70 to 5.7 in TURP group and 18.90 to 6.00 in BNI group. All differences were statistically significant. There was a statistically significant difference in operative time, blood loss, hospital stay, catheterisation timing favouring BNI. Conclusion: TURP and BNI are equally effective in providing symptomatic improvement. BNI has an upper hand in reference to operative time, hospital stay, duration of catheterisation and blood loss.展开更多
