Postoperative urinary retention (POUR) is a common barrier to rapid-discharge hip and knee total joint arthroplasty (TJA). We evaluated the efficacy and safety of catheterization intervention methods for POUR before and after discharge.
A total of 1,659 primary TJAs were retrospectively reviewed. POUR resolutions before and after discharge were evaluated relative to catheterization type and other covariates. Complications before and within 90 days of discharge were quantified. A total of 113 POUR cases comprised the analysis sample of 76 hips and 37 knees in 51 women and 62 men with an average age and body mass index of 68.6 (range 22 to 92) years and 31.7 (range 16 to 49) kg/m2.
POUR resolved before discharge for 82.3% (93/113) of patients, with equivalent resolution rates for intermittent catheterization alone (84.2%, 32/38) compared with indwelling catheterization with or without intermittent catheterization (82.6%, 57/69, P < 0.999), equivalent time to resolution (P = 0.319), and no difference in complication rates (P = 0.999). Complication rates within 90 days of discharge were higher for patients treated with indwelling catheters before discharge (P = 0.049). Resolution before discharge was more likely with increasing body mass index (P = 0.026) and less likely for patients with a history of urinary retention (P = 0.033). 60 percent (12/20) of patients with unresolved POUR were discharged with self-intermittent catheterization and 40% (8/20) with indwelling catheters, with no differences in efficacy and safety based on the catheterization type (P = 0.109).
Before discharge, we observed equivalent resolution rates and equivalent time to resolution for indwelling and intermittent catheterization alone without compromising patient safety. Intermittent catheterization is favored, however, because in situ catheter exposure is dramatically reduced and postdischarge complication rates are lower. Additional research is needed to develop evidence-based POUR guidelines for outpatient TJA.
