Background: Urinary calculus disease is one of the 3 most common urological diseases. It affects about 12% of the world population and has become a worldwide health problem. Of all the urinary tract stones 20% are ureteral stones, of which 70% are found in the distal ureter. The objective of the study is to study the effect of silodosin in the passage of calculi in the distal ureter compared to non-steroidal anti-inflammatory drugs (NSAIDs) (diclofenac sodium) and oral fluids.

Methods: This study included a total of 90 patients between the study period from October 2016 to October 2018. 45 patients were chosen randomly and advised to take plenty of oral fluids and treated with NSAIDs and the other 45 patients were treated with silodosin 8 mg HS for one month along with oral fluids and NSAIDs. After 1 month if the stone was passed successfully, it was confirmed with ultrasonography, if failed, advised for surgery.

Results: Majority of the patients were in the age group of 20-45 yrs. The mean size of the calculus was 5.60 cm on the right side and 5.71 cm on the left side. Out of the 45 patients who were on treatment with silodosin 35 patients had passed the calculi and 10 patients had no results with a success rate of 77.7%. In the 45 patients who were not on silodosin, 8 patients passed the calculi and 37 patients did not pass the calculi. 21 patients among the 45 underwent urethrorenoscopy.

Conclusions: Silodosin is an effective and safe drug in the management of calculi in the distal ureter.
