Scotting OJ, et al. - Three hundred thirty-five consecutive subjects who underwent primary total joint arthroplasty (TJA) using epidural anesthesia were retrospectively evaluated by the researchers in order to assess if not placing an indwelling urinary catheter lead to a greater potential for adverse genitourinary (GU) issues following TJA. When contrasted among catheter and non-catheter groups, no variations in demographics including age, gender, or laterality of surgery were found. There was a variation in the type of surgery. No variation in the American Society of Anesthesiologists score, but a variation in body mass index was observed. No variations in GU complications among subjects with benign prostatic hyperplasia or prostate cancer was ascertained. However, the urinary tract infection rate was greater in the catheter group among cases with a history of prostate disorders (benign prostatic hyperplasia or prostate cancer). Postoperative GU complications were correlated with an elevated median age in years and raised the average length of stay in days. Hence, without the placement of a preoperative indwelling urinary catheter, subjects who underwent TJA under epidural anesthesia exhibited no increased risk of postoperative urological complications. Moreover, the routine use of preoperative catheters can be acknowledged again for this mode of anesthesia.
