AIM: To examine the potential correlation between urethral function and lower urinary tract symptoms (LUTS) in men with benign prostatic hyperplasia (BPH). METHODS: Thirty-one patients with clinical BPH, who were confirmed to have benign prostatic enlargement (BPE) of 20 ml or more, were enrolled into the study. A mark-sheet questionnaire was used for obtaining the LUTS history. Multichannel pressure-flow urodynamic studies were performed and external urethral sphincter pressure (PEUS), intravesical pressure (PVES), and bladder neck pressure (PBN) were recorded both at maximum cystometric capacity and during voiding with 5-microtip transducers, for the purpose of detecting BPE-specific urodynamic findings at different levels within the urethra. RESULTS: There was a positive correlation between hesitancy and detrusor bladder neck dyssynergia (DBND) (P = 0.0011) and between incomplete emptying and low PBN at maximum cystometric capacity (P = 0.0425). The hesitancy proved to have no correlation with bladder neck opening time (TBNO). CONCLUSION: Urodynamic evaluation of urethral function was beneficial for attributing LUTS to clinical BPH. Among various parameters, DBND was the most specific to clinical BPH, suggesting it to be a situation where a steep rise in PBN or prostatic urethral pressure remains greater than the increasing PVES, resulting in sustained difficulty in opening the bladder neck and subsequently the subjective sensation of hesitancy. |
