Comparative study between Tamsulosin, Silodosin and Tadalafil as a medical expulsive therapy for lower ureteral stones.

Objective: To compare the efficacy of Tamsulosin, Silodosin and Tadalafil as a medical expulsive therapy for treatment of distal ureteral calculi. Patients and methods: Over a period of 6 months (January 2022 to June 2022) this prospective randomized study was conducted on 170 patients with distal ureteric stone = 10 mm. Patients were randomly divided into three groups. Patients in group A received Tamsulosin 0.4mg, in group B received Silodosin, and in group C receive Tadalafil 5 mg. Therapy was given for a maximum of 4 weeks. The rate and time of stone expulsion, the analgesic use, attacks of colic and hospital visits for pain, and adverse effects of drugs were recorded. Results: Among 170 patients who were enrolled in study, 20 were lost to follow-up (7, 8, 5 in group A, B, And C respectively). There was a significant higher stone passage rate in group C than group A and B (90% vs. 70% and 76% respectively; p-value = 0.043) and shorter expulsion time in group C (8.7 ± 3.3 days) vs. group A (12.5 ± 5.2 days) and group B (11.3 ± 4.2 days) with (p-value = 0.001)(highly statistically significant with p-value < 0.001) and increased amount of analgesics required in group A (225 ± 115.7 mg) and group B (163 ± 77.5 mg) when compared with group C (120 ± 55.3 mg). Conclusion: Tadalafil is more effective than Tamsulosin and Silodosin in treatment of patients with distal ureteric stones = 10 mm as regard stone expulsion rate, expulsion time with decreased number of colicky episodes and side effects.
