Pharmacological measures to prevent post-operative urinary retention; a prospective randomized study

Area of Science:

• Urology
• Gynecologic Surgery
• Pharmacology

Background:

• Urinary retention is a potential complication following vaginal surgery for genital prolapse.
• Pharmacological agents are sometimes used to manage post-operative urinary function.

Purpose of the Study:

• To evaluate the effect of specific pharmacological agents on post-operative urinary retention after vaginal surgery.
• To compare the incidence of elevated residual urinary volume across different treatment groups.

Main Methods:

• One hundred patients undergoing vaginal surgery for genital prolapse were randomized into four groups.
• Groups received either a control (no medication) or one of three pharmacological agents: distigmine bromide, phenoxybenzamine hydrochloride, or prostaglandin F2 alpha.
• Post-operative residual urinary volume was assessed.

Main Results:

• The control group had an incidence of elevated residual urinary volume of 10.7%.
• All tested pharmacological agents approximately tripled the incidence of elevated residual urinary volume compared to the control.
• Distigmine bromide and prostaglandin F2 alpha showed statistically significant increases (P < 0.05).
• Prostaglandin F2 alpha demonstrated the most significant increase (P < 0.01) when used after anterior repair surgery.

Conclusions:

• The investigated pharmacological agents (distigmine bromide, phenoxybenzamine hydrochloride, prostaglandin F2 alpha) did not prevent, but rather increased, the incidence of post-operative urinary retention after vaginal surgery.
• Prostaglandin F2 alpha showed a particularly marked increase in urinary retention, especially after anterior repair.
• These findings suggest caution in using these agents for managing urinary retention post-vaginal surgery.
