In 52 patients an indwelling transurethral catheter was inserted after gynaecological surgery for 5 days; no patient received antibiotics. At the time of removal of the catheter on the 6th postoperative day and 2 days later (8th postoperative day) a urine culture was set up. At the time of removal of the catheter on the 6th day, 26/52 patients (50%) had significant bacteriuria greater than or equal to 10(5)/ml. In 11 out of the 26 patients with bacteriuria the urine cleared spontaneously within 2 days; on the other hand, 10/26 patients with a negative culture at the time of removal of the catheter had significant bacteriuria 2 days later. As a group these women also had delayed spontaneous onset of voiding and persistence of residual urine. Younger patients (less than 45 years) had significantly fewer bacteriurias on the 6th day than older patients. A positive urine culture at the time of removal of the catheter should be treated with antibiotics; a negative urine culture should be repeated whenever spontaneous voiding is delayed, when there is persistent residual urine, or when the clinical signs of urinary tract infection are present.
52例患者在妇科手术后留置经尿道导管5天；无一例患者接受抗生素治疗。在术后第6天拔除导管时以及2天后（术后第8天）进行尿培养。在术后第6天拔除导管时，52例患者中有26例（50%）有显著菌尿，菌数大于或等于10⁵/ml。在26例有菌尿的患者中，11例的尿液在2天内自行清除；另一方面，在拔除导管时培养结果为阴性的26例患者中，有10例在2天后出现显著菌尿。总体而言，这些女性还存在排尿自发开始延迟和残余尿持续存在的情况。较年轻的患者（小于45岁）在第6天的菌尿明显少于年长患者。拔除导管时尿培养阳性应使用抗生素治疗；当排尿自发延迟、存在持续残余尿或出现尿路感染的临床体征时，无论尿培养结果如何均应重复检查。
