Efficacy and safety of tadalafil in ureteric stent related symptoms: a double blind, prospective, randomised study
Keywords:Tadalafil, Tamsulosin, Ureteral stent symptom questionnaire
Background: Is tadalafil effective and safe in ureteric stent related symptoms? The objective of this trial is to study the efficacy and safety of tadalafil and compare it with tamsulosin in relieving ureteric stent related symptoms by using ureteral stent symptom questionnaire.
Methods: Total 144 patients with dj stent symptoms were randomized into two groups with 72 patients in each. Group A patients were given tadalafil 5mg and Group B, tamsulosin 0.4mg for 2 weeks. Ureteral stent symptom questionnaire was filled on 7th day and on 21st day after stent insertion. Statistically significant difference between groups was determined by the t-test, Mann-Whitney U-test, Pearson Chi-square test or Fisher's exact test. Comparison between quantitative time related variables was done by Wilcoxon Signed Rank test. All the statistical tests were two-sided and were performed at a significance level of α=.05.
Results: Tamsulosin was found more effective then tadalafil in decreasing mean urinary index (p=0.004). Tadalafil caused significant decrease in body pain (p=0.006) and improvement in general health index score, work performance and sex score (P value= 0.041, <0.001 and <0.015 respectively) as compared to tamsulosin. Additional problems score improvement and analgesic use were found comparable in 2 groups (p value =0.193, 0.070 respectively). Adverse effect with both the drugs were minimal, mild to moderate and self-limiting.
Conclusions: Tadalafil found more effective then Tamsulosin in relieving body pain, sexual symptoms and improving general health and work performance but less effective in improvement of urinary symptoms.
