Summary
Postoperative urinary retention occurred in 6% of patients, particularly after laparotomy and long anesthetics. Opiate analgesia significantly increased retention risk, suggesting reduced bladder sensation as a key cause.
Area of Science:
- General Surgery
- Anesthesiology
- Urology
Background:
- Postoperative urinary retention (PUR) is a common complication following general surgery.
- Factors influencing PUR incidence and severity require further investigation.
Purpose of the Study:
- To determine the incidence of postoperative urinary retention in general surgical patients.
- To identify risk factors associated with the development of PUR.
Main Methods:
- Prospective study of 280 general surgical patients.
- Data collection on patient demographics, surgical procedures, anesthetic details, and analgesia.
- Monitoring for the need for urinary catheterization post-surgery.
Main Results:
- Overall incidence of PUR was 6% (18/280 patients).
- Higher incidence observed after laparotomy (23%) compared to minor procedures.
- Longer anesthetics (>60 min), ventilation, and opiate analgesia were significantly associated with increased PUR.
- Intravenous opiate administration showed a higher retention rate than intramuscular injections.
Conclusions:
- Postoperative urinary retention is multifactorial, with surgical site (laparotomy) and anesthetic factors (duration, ventilation) playing significant roles.
- Opiate analgesia is a notable risk factor for PUR.
- Diminished bladder sensation appears to be a more significant contributor to PUR than anxiety or local pain.
