This clinic trial, randomized and blinded was done to determine efficient whether reducing transurethral Foley catheterization from 3 days to 1 would lead to fewer urinary (UTI) tract infections without retention becoming a problem. Fifty women undergoing vaginal plastic repair to either 1 or 3 days catheterization. Of 25 patients catheterized for both group postoperative urinary retention occurred in 2 (8%) and required a new catheter. Of 25 patients catheterized for 1 day UTI was diagnosed in 1 (4%) and in 5(20) of those catheterized for 3 days, mean postoperative stay was 2 day for patients catheterized for 1 day and 3 days for those for 3 days. The differences are statistically significant, therefore catheter time may safely be reduced to 1 day. This may be associated with a reduced rate postoperative urinary retention, urinary tract infection, and stay postoperative.
这项随机双盲临床试验旨在确定将经尿道留置导尿管时间从3天减至1天是否能有效减少泌尿系统感染（UTI），同时避免尿潴留问题。五十名接受阴道整形修复手术的女性被随机分为留置导尿管1天或3天两组。两组各25例患者中，术后发生尿潴留且需重新留置导尿管的均为2例（8%）。1天组25例患者中，1例（4%）被诊断为UTI；3天组25例患者中，5例（20%）被诊断为UTI。1天组患者术后平均住院时间为2天，3天组为3天。差异具有统计学意义，因此导尿管留置时间可安全减至1天。这可能与术后尿潴留发生率降低、泌尿系统感染减少以及术后住院时间缩短有关。
