BACKGROUND:Postoperative urinary retention is a common complication after surgical procedures. It can cause bladder dilatation, infection, and even sepsis. Carbachol/diazepam and alfusozine have been reported to lower the incidence of postoperative urinary retention, but no study showed the benefits of these drugs in a randomized, placebo-controlled trial. STUDY DESIGN: We used a double blind, placebo-controlled trial in which 249 patients with postoperative urinary retention were randomly assigned to receive carbachol/diazepam (n = 72), alfusozine (n = 82), or placebo (n = 95). The primary endpoint was miction within 2 hours after taking the medication. RESULTS: There was no significant difference in miction frequency after taking the medication among the three groups (p = 0.31). The miction rate was 60% for patients in the alfusozine group, 61% in the carbachol/diazepam group, and 51% in the placebo group. CONCLUSIONS:Alfusozine and carbachol/diazepam had no apparent benefit on the incidence of postoperative urinary retention.
