Findings

The α-adrenergic receptor blocker tamsulosin does not increase passage of small, symptomatic ureteral stones, reports a randomized clinical trial in JAMA Internal Medicine.

The two-phase trial included 512 adults seen in the emergency department with symptomatic ureteral stones. All patients had a symptomatic ureteral stone measuring less than 9 mm in diameter (mean 3.8 mm) on computed tomography. About three-fourths of patents were male and one-fourth were non-white; the mean age was 40.6 years.

The study was published in the British Medical Journal.
