- Abstract
Introduction: Alpha blockers are widely used in the treatment of primary bladder neck obstruction; however, evidence for objective urodynamic efficacy is scarce. We studied the effect of the uroselective α1-blocker tamsulosin on urodynamic parameters in male patients with type I primary bladder neck obstruction. Methods: A single center prospective observational study was carried out from July 2013 to February 2015. Male patients (18–50 years) with type 1 primary bladder neck obstruction were recruited. Selected patients were started on tablet tamsulosin 0.4 mg once daily for 3 months. International prostate symptom score (IPSS), uroflow and urodynamic studies were done pre- and post-treatment. Primary outcome was decreased in minimum detrusor pressure at maximum flow rate by 15%. Wilcoxon‑matched pair signed‑rank test was used. Results: Of 39 patients recruited, 21 patients completed the follow-up as per protocol and were analyzed. Mean age was 41 years. 57% patients achieved the primary outcome (median detrusor pressure pre- and post-treatment were 71 and 56 cm of water, P < 0.001). Similarly, median values for bladder outlet obstruction index (BOOI) and IPSS decreased from 59 to 38 (P < 0.001) and 22 to 12 (P < 0.001), respectively. Median maximum flow rate increased from 8 to 10 ml (P = 0.05). Pretreatment BOOI of >60 was associated with poor outcomes. Conclusions: Tamsulosin 0.4 mg once a day is effective in reducing bladder outlet obstruction on pressure flow studies in patients with primary bladder neck obstruction type 1.
