OBJECTIVES

• To determine the incidence of severe pain after ureteric stent removal.

• To evaluate the efficacy of a single dose of a non-steroidal anti-inflammatory drug (NSAID) in preventing this complication.

PATIENTS AND METHODS

• A prospective, randomised, double-blind, placebo-controlled trial was performed at our institution.

• Adults with an indwelling ureteric stent after ureteroscopy were randomised to receive either a single dose of placebo or an NSAID (rofecoxib 50 mg) before ureteric stent removal.

• Pain was measured using a visual analogue scale (VAS) just before and 24 h after stent removal

• Pain medication use after ureteric stent removal was measured using morphine equivalents.

RESULTS

• In all, 22 patients were enrolled and randomised into the study before ending the study after interim analysis showed significant decrease in pain level in the NSAID group.

• The most common indication for ureteroscopy was urolithiasis (14 patients).

• The proportion of patients with severe pain (VAS score of ≥7) during the 24 h after ureteric stent removal was six of 11 (55%) in the placebo group and it was zero of 10 in the NSAID group (P < 0.01).

• There were no complications related to the use of rofecoxib.

CONCLUSIONS

• We found a 55% incidence of severe pain after ureteric stent removal.

• A single dose of a NSAID before stent removal prevents severe pain after ureteric stent removal.
