Silodosin vs tamsulosin in the management of distal ureteric stones: A prospective randomised study

Objectives: To compare the efficacy of silodosin (8 mg) vs tamsulosin (0.4 mg), as a medical expulsive therapy, in the management of distal ureteric stones (DUS) in terms of stone clearance rate and stone expulsion time. Patients and methods: A prospective randomised study was conducted on 115 patients, aged 21-55 years, who had unilateral DUS of 610 mm. Patients were divided into two groups. Group 1 received silodosin (8 mg) and Group 2 received tamsulosin (0.4 mg) daily for 1 month. The patients were followed-up by ultrasonography, plain abdominal radiograph of the kidneys, ureters and bladder, and computed tomography (in some cases). Results: There was a significantly higher stone clearance rate of 83% in Group 1 vs 57% in Group 2 (P = 0.007). Group 1 also showed a significant advantage for stone expulsion time and analgesic use. Four patients, two in each group, discontinued the treatment in first few days due to side-effects (orthostatic hypotension). No severe complications were recorded during the treatment period. Retrograde ejaculation was recorded in nine and three patients in Groups 1 and 2, respectively. Conclusion: Our data show that silodosin is more effective than tamsulosin in the management of DUS for stone clearance rates and stone expulsion times. A multicentre study on larger scale is needed to confirm the efficacy and safety of silodosin. (C) 2015 Arab Association of Urology. Production and hosting by Elsevier B.V.
