This study was to investigate whether urinary catheterization could be avoided for patients undergoing total knee arthroplasty (TKA) under general anesthesia with saphenous nerve block. 314 patients from a single surgical team were randomized to receive either an indwelling urinary catheter or no urinary catheter before the surgery. The results revealed that the prevalence of postoperative urinary retention (POUR) was quite low in both groups (5.7% vs 6.4%, P=1). Additionally, the prevalence of urinary tract infection was significantly higher in patients using an indwelling catheter (5.1% vs 0.6%, P=0.036). We also identified age, male gender, ASA grade, benign prostatic hypertrophy, intraoperative intravenous fluid and duration of surgery as the risk factors for POUR in these patients.
本研究旨在探讨在全身麻醉联合隐神经阻滞下行全膝关节置换术（TKA）的患者是否可以避免留置导尿。来自单一手术团队的314例患者被随机分为两组，一组在手术前留置导尿管，另一组不留置导尿管。结果显示，两组患者术后尿潴留（POUR）的发生率均相当低（5.7% 对 6.4%，P = 1）。此外，使用留置导尿管的患者尿路感染的发生率显著更高（5.1% 对 0.6%，P = 0.036）。我们还确定了年龄、男性、美国麻醉医师协会（ASA）分级、良性前列腺增生、术中静脉输液量和手术时长为这些患者发生POUR的危险因素。
