Men older than 70 years, patients receiving spinal anesthesia and those with postoperative patient-controlled analgesia had an increased risk of urinary retention after total hip arthroplasty, according to study results.
Researchers described the incidence and risk factors for postoperative urinary retention among 376 men undergoing total hip arthroplasty (THA). The researchers identified risk factors using multivariate regression analysis.

Results showed 39.9% of men developed urinary retention following THA. Independent risk factors for urinary retention included patient-controlled analgesia, use of spinal anesthesia and patient age of 70 years and older. The researchers also found BMI, American Society of Anesthesiologists physical status, hypertension, diabetes mellitus, prostate pathology, smoking, average pain during the first 24 hours after surgery and length of surgery were potential risk factors that were not confirmed.
Among patients with urinary retention who had a catheter inserted, two developed a urinary tract infection vs. no patients without urinary retention, according to the researchers. – by Casey Tingle
