Does tamsulosin decrease postoperative urinary retention in spine surgery? A double-blind, randomized controlled...

Area of Science:

• Urology
• Anesthesiology
• Neurosurgery

Background:

• Postoperative urinary retention (POUR) is a common complication after spine surgery.
• Alpha-1 adrenergic receptor antagonists, like tamsulosin, are sometimes used to manage lower urinary tract symptoms.

Purpose of the Study:

• To investigate the efficacy of preoperative tamsulosin in preventing postoperative urinary retention in male patients undergoing elective spine surgery.

Main Methods:

• A randomized, double-blind, placebo-controlled trial involving 610 male patients aged 50-85 years.
• Patients received either oral tamsulosin (0.4 mg) or placebo for 5 days preoperatively and 2 days postoperatively.
• Exclusion criteria included prior use of alpha-adrenergic blockers, urological issues, or concurrent cataract surgery.

Main Results:

• A total of 497 patients were analyzed. The overall rate of postoperative urinary retention was 9.7%.
• Tamsulosin showed no significant difference compared to placebo in reducing the rate of postoperative urinary retention (9.4% vs 9.9%, p=0.96).
• Multivariate analysis confirmed that the study drug was an insignificant factor in predicting postoperative urinary retention.

Conclusions:

• Perioperative tamsulosin did not demonstrate a significant effect in reducing postoperative urinary retention in male patients undergoing elective spine surgery.
• The findings do not support the routine prophylactic use of tamsulosin for preventing POUR in this population.
• Further research is needed to identify potential subpopulations that might benefit from prophylactic tamsulosin.
