Abstract | PURPOSE: MATERIALS AND METHODS: A total of 23 children without anatomical or neurogenic abnormalities presented with lower urinary tract symptoms refractory to conservative measures. All children had increased post-void residual urine or abnormal uroflowmetry in the absence of pelvic floor activity suggestive of bladder neck dysfunction. All patients were administered tamsulosin daily. Voiding diaries, blood pressure, uroflowmetry studies and patterns along with assessment of post-void residual urine were obtained before and after beginning tamsulosin in all children. RESULTS: Median duration of tamsulosin therapy was 7 months, and patient followup was 20 months. The number of voiding and incontinent episodes significantly decreased during treatment compared to baseline (p <0.05). Mean blood pressures before and during tamsulosin treatment were 98/55 mm Hg and 110/61 mm Hg, respectively. Significant increases in average and maximum urinary flow rates along with reduction in post-void residual urine were observed during tamsulosin therapy compared to baseline values (p <0.01). A 50% reduction in the number of abnormal uroflow patterns was observed with tamsulosin therapy. CONCLUSIONS:
Tamsulosin demonstrated no clinically significant effect on blood pressure, while proving to be a safe and effective treatment option for lower urinary tract symptoms in a select pediatric population.
