A PROSPECTIVE STUDY COMPARING TAMSULOSIN AND SILODOSIN IN MEDICAL EXPULSIVE THERAPY FOR LOWER URETERIC STONES
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2016, Vol 5, Issue 59
Abstract
The urinary stone disease is one of the most common afflictions of the modern society and it has been described since antiquity with the westernization of global culture. The efficacy of mini-invasive therapies, such as Extracorporeal Shock Wave Lithotripsy [ESWL] and ureteroscopy are not risk free, are problematic and are quite expensive. Recently, the use of watchful waiting approach has been extended by using Pharmacotherapy. This can reduce symptoms and facilitate stone expulsion. MATERIALS AND METHODS This prospective randomised study was conducted between September 2015 and May 2016 at Rajarajeshwari Medical College and Hospital, Bangalore. The cohort comprised 100 adult patients (54 men and 46 women) who presented with a symptomatic, unilateral, single, uncomplicated lower ureteric stone of ≤ 10 mm. Patients were randomized into two equal groups, 50 (50%) patients received a daily single dose of tamsulosin 0.4 mg for 28 days and 50 (50%) patients received a daily single dose of silodosin 8 mg for 28 days. Both groups were compared in terms of patient’s demographics, socioeconomic status, stone size and side, type of MET, stone expulsion rate, stone expulsion time, number of pain episodes, need for analgesics use and incidence of side effects. Subgroup analysis was performed according to stone size ≤ or > 5 mm. RESULTS No significant differences among the two groups for patient’s age, gender, stone side and stone size. Spontaneous stone expulsion rate within 28 days was observed in 44 (88%) patients in the tamsulosin group and in 45 (90%) patients in the silodosin group without statistically significant differences. There were no statistically significant differences observed in terms of mean expulsion time, mean number of pain episodes and need for analgesics. Retrograde ejaculation was significantly higher in the silodosin arm, while the incidence of side effects related to peripheral vasodilation were higher in the tamsulosin arm, but it was statistically insignificant. CONCLUSION Tamsulosin and silodosin are equally effective as MET for distal ureteric stones sized 10 mm or smaller. MET with silodosin is associated with a lower incidence of side effects related to peripheral vasodilation, but a higher incidence of retrograde ejaculation when compared to tamsulosin. However, a multicentre study on a larger scale is needed to evaluate the current medicines.
