Catheterization, which is widely accepted as an important factor to urinary tract infection, is routinely done during cesarean section. This randomized study was conducted to compare the incidence of urinary tract infection between patients who underwent cesarean section using intermittent catheterization and indwelling catheterization, at the Department of Obstetrics and Gynecology, Ramathibodi Hospital from August 1991 to December 1991. Sixteen of 51 patients (31.4%) of the intermittent group and 9 of 47 patients (19.1%) of the indwelling group developed urinary tract infection. The difference was not statistically significant. Of the patients in the intermittent group 39.2 per cent were found to have postoperative urinary retention requiring recatheterization, whereas all cases in the indwelling group could void after its removal. Klebsiella pneumoniae was the commonest isolated organism. Indwelling catheterization was concluded to be the favourable method.
导尿术被广泛认为是导致尿路感染的一个重要因素，在剖宫产手术中经常进行。本随机研究旨在比较1991年8月至1991年12月期间在拉玛提波地医院妇产科接受剖宫产手术的患者中，采用间歇性导尿和留置导尿的患者尿路感染的发生率。间歇性导尿组51例患者中有16例（31.4%）发生尿路感染，留置导尿组47例患者中有9例（19.1%）发生尿路感染。差异无统计学意义。间歇性导尿组中39.2%的患者术后出现尿潴留需要再次导尿，而留置导尿组所有患者在拔除导尿管后均能自行排尿。肺炎克雷伯菌是最常见的分离出的病原体。得出的结论是留置导尿是较好的方法。
