Outcome of Transurethral Incision of the Bladder Neck in Patients with Primary Bladder Neck Obstruction
Keywords:
Primary bladder neck obstruction, transurethral incision, urodynamics, lower urinary tract symptomsAbstract
Background: Primary bladder neck obstruction (PBNO) is a functional outlet obstruction that impairs urinary flow and leads to significant lower urinary tract symptoms (LUTS). Transurethral Incision of the Bladder Neck (TUIBN) is a standard surgical approach that offers effective decompression. However, regional data from Bangladesh are limited to the aforementioned studies. This study aimed to evaluate the clinical and urodynamic outcomes of TUIBN in patients with PBNO.
Methods: This cross-sectional observational study was conducted at the Department of Urology, Bangladesh Medical University, Dhaka, from June 2023 to July 2024. Forty patients diagnosed with PBNO underwent TUIBN. Demographic data, symptoms, and urodynamic parameters were collected and analyzed using SPSS version 25. Pre- and postoperative variables were compared using paired t-tests, with p < 0.05 considered significant.
Results: The mean age of the patients was 43.9 ± 10.6 years, and 90% were male. Qmax improved significantly from 7.6 ± 2.3 to 18.4 ± 4.1 mL/s (p < 0.001), whereas postvoid residual urine decreased from 145.2 ± 68.7 to 38.5 ± 22.4 mL (p < 0.001). The IPSS and quality of life scores also improved markedly. The overall success rate was 85%, with minor complications, including transient dysuria (22.5%) and hematuria (15%).
Conclusion: TUIBN is a safe and effective intervention for PBNO, providing significant symptomatic and functional improvements with low morbidity.
