A prospective double-blinded placebo controlled randomized study was conducted in our institute to compare the efficacy of oral Silodosin, an alpha 1 selective antagonist and Diclofenac in relieving pain after stent removal. All patients with unilateral stent placement following renal and ureteric stone endoscopic surgery were randomized into four groups: group A (Placebo), group B (Diclofenac), group C (Silodosin) and group D (combination of Diclofenac and Silodosin). Visual analogue score (VAS score) and other relevant parameters were assessed during OPD visit. Patients were handed over randomized drug envelope and asked to take the medications one hour before the stent removal. Patients were contacted 24 h after stent removal and relevant parameters were recorded. The mean VAS scores were significantly decreased in Diclofenac (2.9), Silodosin (3.08) and combination group (2.85) when compared to placebo (4.20) (p < 0.001). However there was no statistically significant difference in VAS scores between the treatment groups, i.e., group B, C and D (p > 0.5). Analgesics requirement and severe pain rates were not significantly reduced (p = 0.07, 0.35) in the three treatment groups when compared to placebo. Thus Silodosin and Diclofenac, both are effective in preventing pain after stent removal.
