Comparison of two agents in prevention of urinary retention after benign anorectal surgery

Abstract
In an attempt to substantiate the efficacy of Urecholine and Dibenzyline [phenoxybenzamine] in prevention of urinary retention, 263 patients who had rectal surgery for benign anorectal abnormalities were divided into 3 comparable groups; 1 was given Urecholine, another was given Dibenzyline in 10 mg doses orally, 4 and 8 h after surgery and the 3rd group was given nothing as a control. The control group had a higher incidence of urinary retention 28.2%, but Dibenzyline did not prevent urinary retention in 20% of the patients and was no more effective than Urecholine at 22.4%.
