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

In an attempt to substantiate the efficacy of Urecholine and Dibenzyline in prevention of urinary retention, 263 patients who had rectal surgery for benign anorectal abnormalities were divided into three comparable groups; one group was given Urecholine, another group was given Dibenzyline in 10-mg doses orally, four and eight hours after surgery and the third group was given nothing as a control. The control group had a higher incidence of urinary retention 28.2 per cent; but Dibenzyline did not prevent urinary retention in 20 per cent of the patients and was no more effective than Urecholine at 22.4 per cent.
