Objective: To investigate the therapeutic efficacy of transurethral incision of the bladder neck (TUI-BN) in men with primary bladder neck dysfunction (BND).
Materials and methods: Men who were diagnosed with BND refractory to alpha-adrenergic blockade and who underwent TUI-BN between 1999 and 2009 were enrolled in this study. Video-urodynamic studies (VUDS) were performed
at baseline and repeated at 3-6 months for postoperative evaluation. Therapeutic results assessed by patient perception of bladder condition (PPBC) and data on maximum flow rate (Qmax), voided volume, post-voiding residual (PVR) amount, and detrusor pressure at Qmax (PdetQmax) were compared between baseline and after TUI-BN.
Results: A total of 46 patients completed the study. Compared with baseline data, postoperative VUDS revealed that PdetQmax had decreased in 28 patients, increased in 12, and there was persistent detrusor underactivity in 6. Overall, Qmax increased (baseline vs. postoperatively, 5.72± 4.77 mL/s vs. 13.8± 8.02 mL/s, p < 0.001), voided volume increased (146 ± 130 mL vs. 185± 109 mL, p=0.03) and PVR volume decreased (214 ± 200 mL vs. 108 ± 136 mL, p < 0.001) significantly after TUI-BN. PdetQmax increased significantly from 8.7 ± 9.8 cmH2O to 28.3± 13.8 cmH2O (p = 0.021) in the increased-Pdet group and PdetQmax decreased significantly from 65.2± 47.1 cmH2O to
40.1 ± 32.6 cmH2O (p=0.012) in the decreased-Pdet group. PPBC improved by 2 scales in 36 (78%) patients, including 22 (79%) in the decreased-Pdet group and 10 (83%) in the increased-Pdet group. Four (67%) of six patients with
detrusor underactivity could void with the aid of abdominal pressure after TUI-BN.
Conclusion: TUI-BN is effective for primary BND diagnosed by VUDS. Patients with either high or low PdetQmax and BND benefited from TUI-BN. |
