Abstract: A prospective study of sixty-four men was conducted before they underwent a total hip arthroplasty to try to identify the factors that are predictive of postoperative urinary retention. Although neither the urological history nor the physical examination provided information that was helpful in accurately identifying the patients who were at risk, those whose peak urinary flow rate was less than seventeen milliliters per second did have a statistically significant likelihood of the development of urinary retention. A system of management that we hope will reduce the incidence of this complication is proposed.
