Is Hysterectomy a Risk Factor for Urinary Retention? A Retrospective Matched Case Control Study

Area of Science:

• Gynecologic Surgery
• Urology
• Postoperative Complications

Background:

• Postoperative urinary retention is a common complication following gynecologic surgery.
• Identifying risk factors is crucial for improving patient outcomes and reducing hospital stays.

Purpose of the Study:

• To compare the incidence of urinary retention in patients undergoing endoscopic hysterectomy versus non-hysterectomy endoscopic gynecologic procedures.
• To determine if hysterectomy is an independent risk factor for postoperative urinary retention.

Main Methods:

• A retrospective case-control study was conducted, matching 200 endoscopic hysterectomy cases with 200 non-hysterectomy endoscopic gynecologic surgery controls.
• Matching was performed based on operative time.
• Data on patient demographics, perioperative opioid administration, and estimated blood loss were collected and analyzed.

Main Results:

• Patients undergoing endoscopic hysterectomy had a significantly higher rate of urinary retention (26.5%) compared to the non-hysterectomy group (13%).
• Endoscopic hysterectomy was associated with double the rate of urinary retention, even after adjusting for perioperative opioid use and operative time (relative risk = 2.3).
• Factors like age, opioid use, and blood loss showed differences between groups, but operative time was the only significant factor for retention in the non-hysterectomy group.

Conclusions:

• Endoscopic hysterectomy is an independent and major contributor to postoperative urinary retention.
• The increased risk of urinary retention associated with hysterectomy warrants further investigation and potential preventative strategies.
