Postoperative urinary retention (POUR) remains a common complication after total joint arthroplasty (TJA). The objective of this study was to determine the incidence and risk factors for POUR in fast-track TJA emphasizing rapid mobilization, multimodal analgesia, and shorter hospital stay.


Our institutional joint registry was queried for patients who underwent primary TJA between January 2016 and November 2017. The primary outcome was the development of POUR. A panel of demographic, intraoperative, and postoperative variables was investigated. Multivariable regression analyses were performed to control for possible confounding factors.


One hundred eighty-seven patients who underwent total hip arthroplasty (THA) and 191 patients who underwent total knee arthroplasty (TKA) were included in the study. Forty percent of TKA and 36% of THA patients developed POUR requiring bladder catheterization. Among THA patients, POUR was significantly associated with age >60 years, intraoperative fluid volume >1350 mL, and intraoperative placement of an indwelling bladder catheter (P = .016, P = .035, and P < .001, respectively). Among TKA patients, POUR was only significantly associated with intraoperative indwelling bladder catheter placement (P < .001).


The most significant risk factors for POUR in modern-day fast-track TJA are iatrogenic. Routine intraoperative placement of an indwelling bladder catheter and fluid administration exceeding 1350 mL, especially in patients older than 60 years, are discouraged.
