Recommendations for alpha-blockers have shifted in the conservative management of ureteral stones. It is unknown whether real-life practices regarding alpha-blocker prescriptions reflect updates in evidence. This study aimed to characterise alpha-blocker prescriptions for conservatively managed ureteral stones and relate this to recent literature. This was a retrospective audit, 01/01/2014 to 01/01/2019, of emergency acute renal colic presentations. Patients were included if they had a confirmed ureteral stone and were conservatively managed. The rates of alpha-blocker prescriptions were analysed using interrupted time-series analyses. May 2015 was selected as the cut-point to analyse before and after trend lines. Results were stratified by stone size and location. Tamsulosin and prazosin prescriptions were also compared. This study included 2163 presentations: 70.4% were stones ≤5 mm and 61.4% were proximal stones. Altogether, 24.7% of presentations were prescribed alpha-blockers. There was a fall in alpha-blocker prescription rates from before to after May 2015, regardless of stone size or location (p < 0.001). Since May 2015, however, there was a monthly rate increase of 0.5% for patients with stones >5mm. This study demonstrated a significant shift in rates of alpha-blocker prescriptions, possibly related to the influence of updates in available high-quality evidence. |
