Background

Postoperative urinary retention (POUR) following total joint arthroplasty (TJA) presents a significant barrier to outpatient and early discharge TJA. This study examined the incidence and risk factors for acute POUR in a modern, evidence-based, outpatient, and early discharge TJA program.

Methods

Prospectively recorded data on 685 consecutive primary unilateral TJAs discharged the day of or day after surgery were retrospectively reviewed. POUR was diagnosed by a perioperative internal medicine specialist. Univariate analysis of potential predictors was performed, followed by binary logistic regression (BLR) testing of predictors with P ≤ .25.

Results

After exclusions for confounds, the final analysis sample consisted of 633 procedures. The overall incidence of POUR was 5.5% (3.9% for same day discharges). Male gender, history of urinary retention, use of rocuronium, use of glycopryrrolate, use of neostigmine, fentanyl spinals, and the absence of an indwelling urethral catheter were associated with acute POUR and met criteria for entry into multivariate BLR. Seventeen additional predictors, including kidney disease and outpatient surgery were unrelated to POUR. In the final BLR model ( P = .001), male patients who received glycopyrrolate with neostigmine had a 34% probability of developing POUR, which declined to 2.8% in the absence of these risk factors.

Conclusion

Despite a relatively low incidence of 5.5%, avoidance of anticholinergics and cholinesterase inhibitors during anesthesia should be carefully considered in outpatient TJA, particularly in stand-alone ambulatory surgery centers.
