Effect of Older Age on Postoperative Urinary Retention After Prolapse Surgery.

IMPORTANCE

Postoperative urinary retention (POUR) is common after reconstructive pelvic surgery. Little is known about the relationship between older age (≥70 years) and POUR after pelvic organ prolapse surgery.

OBJECTIVES

We aimed to investigate the relationship between age ≥70 years and POUR. Secondarily, we aimed to determine if duration of urinary catheterization differed by age in women with POUR.

STUDY

DESIGN

This was a secondary analysis of a dual-center retrospective study on perioperative adverse events in biologic females aged ≥61 years undergoing prolapse surgery. The primary outcome was POUR, defined as a failed retrograde voiding trial requiring bladder catheterization. The secondary outcome was duration of temporary bladder catheterization. We developed a stepwise multivariable logistic regression model, which included relevant variables with P < 0.10 on univariate analyses and a forced age variable.

RESULTS

In this cohort of 2,665 women, mean ± standard deviation age was 71.2 ± 6.7 years, and 54.6% were ≥70 years, POUR occurred in 830 (31.1%) patients. Women with POUR had a lower body mass index and were more likely to have undergone a vaginal prolapse surgery and concomitant hysterectomy/incontinence procedure ( P < 0.05). They had higher estimated blood loss (75 vs 50 mL, P < 0.001). On multivariable logistic regression, age ≥70 years was not associated with POUR (adjusted odds ratio 1.02, 95% CI [0.83-1.26]). Age ≥70 years was associated with longer duration of catheterization (5 vs 4 days, P < 0.01).

CONCLUSION

Age was not associated with POUR when controlling for other clinical factors (body mass index, surgical approach, concomitant hysterectomy/incontinence surgery, and estimated blood loss). These factors may affect POUR in older women and should be considered in perioperative management.
