Study Objective:
To identify risk factors associated with postoperative urinary retention in patients undergoing outpatient minimally invasive hysterectomy.
Design:
A retrospective cohort study.
Setting:
An academic medical center.
Patients:
All patients undergoing outpatient minimally invasive hysterectomy between January 2013 and July 2018 were considered for inclusion in the study.
Interventions:
Outpatient laparoscopic, vaginal, or robotically assisted laparoscopic hysterectomy.
Measurements And Main Results:
Four hundred forty-four patients met the inclusion criteria. Postoperative urinary retention occurred in 94 patients, and 347 patients successfully passed their voiding trial in the postanesthesia care unit for a pass rate of 79%. Demographic characteristics were similar, except patients who experienced postoperative urinary retention were less likely to be menopausal (23.4% vs 34.7%, p = .038). Those with urinary retention received more perioperative opioids (morphine milligram equivalent of 14.4 mg vs11.2 mg, p = .012), had longer operative times (122.9 ± 55.6 vs 95.7 ± 42.3 minutes, p < .01), and experienced more blood loss (105.3 ± 134.4 vs 78.5 ± 86.8 mL, p = .025). The rate of urinary tract infections was similar. Logistic regression analysis showed that the route of hysterectomy and age were not associated with an increased risk for urinary retention, whereas a longer operative time and higher doses of perioperative opioid use were.
Conclusion:
In patients undergoing minimally invasive outpatient hysterectomy, a longer operative time and increased perioperative narcotic use increases the risk of postoperative urinary retention.

01:13Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...

In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
