Abstract

Objectives

In adolescent idiopathic scoliosis (AIS) patients undergoing posterior spinal instrumented fusion (PSIF), we aimed to answer these questions: (1) is there a difference in postoperative urinary retention (UR) rates among patients who had removal of their Foley catheters before vs. after discontinuation of epidural analgesia (EA)? (2) Can the timing of Foley catheter removal be an independent risk factor for postoperative UR requiring recatheterization? (3) Is there an incurred cost related to treating UR?

Study design

Retrospective cohort.

Background

EA has been widely used for postoperative pain control after PSIF for AIS. In these patients, removing the Foley catheter, inserted for intraoperative monitoring of urine output, is indicated in the early postoperative period. However, a controversy exists as to whether it should be removed before or after the EA has been discontinued.

Methods

A single-institution, longitudinally maintained database was queried to identify 297 patients who met specific inclusion and exclusion criteria. Patient characteristics and the order and timing of removing the urinary and epidural catheters were collected. Rates of UR were statistically compared in patients who had early vs. late urinary catheter removal. A univariate and multivariate regression analysis was conducted to identify independent risk factors. Hospital episode costs were analyzed.

Results

Patients who had early (n = 66, 22%) vs. late (n = 231, 78%) urinary catheter removal had a significantly higher incidence of UR requiring recatheterization (15 vs. 4.7%, p = 0.007). Patient with early removal were almost 4 times more likely to develop UR requiring recatheterization [odds ratio (OR) 3.8, 95% confidence interval (CI) 1.5–9.7, p = 0.005]. UR incurred additional costs averaging $15,000/patient (p = 0.204).

Conclusion

In patients who had PSIF for AIS, removal of a urinary catheter before discontinuation of EA is an independent risk factor for UR, requiring recatheterization and associated with increased cost.
