Tamsulosin versus Tadalafil as Medical Expulsive Therapy of Distal Ureteric Stones: A Comparative Study

Abstract

Introduction: The management of patients with ureteral calculi has changed dramatically in the current era, with the conservative approach being the primary focus, its main benefit being minimum patient morbidity. The use of the expectant approach for distal ureteric stones can be extended with the use of adjuvant medical expulsive therapy (MET), which is able to reduce symptoms and facilitate stone expulsion. The present study was thus conducted to determine single best monotherapy for medical expulsive therapy of distal ureteric stones by comparing Tadalafil and Tamsulosin. Material & Methods: A hospital based comparative study was conducted at Department of Surgery of a tertiary care hospital. A total of 60 eligible cases of lower ureteric calculus were included in the study. These 60 patients were then divided into 2 groups of 30 each to receive one of the two medical therapy i.e. either Tadalafil or Tamsulosin. Data was analyzed using statistical software SPSS ver. 21. Results: Mean expulsion of calculi was significantly earlier in patients managed by Tadalafil as compared to Tamsulosin (13.1 vs 16.92 days; p<0.05). Complete expulsion was seen in 86.7% cases on Tadalafil as compared to only 63.3% cases on Tamsulosin (p<0.05). Mean analgesic use (2.69 vs 1.81; p<0.05) and episodes of colicky pain (1.41 vs 0.43; p<0.05) were significantly higher in patients managed by Tamsulosin. The numbers of hospital visits required during treatment were also more with Tamsulosin, but the difference did not reach significance levels (2.56 vs 2.02 days; p-0.06). No difference was seen in the adverse effect profile of both drugs. Conclusion: Our results showed that Tadalafil has a significantly higher ureteric stone expulsion rate. Tadalafil also provides early stone expulsion, a greater decrease in colicky pain episodes, and a greater decrease in analgesic requirement. Both drugs are safe, effective, and well tolerated with minor side effects. Thus Tadalafil is safe, efficacious, and well tolerated as medical expulsive therapy for distal ureteric stones.
