Prophylactic antibiotics are usually not recommended for an in and out catheterization. However procedures involving similar catheterizations like micturition cystourethrogram (MCUG) and cystometrogram are being performed under prophylactic antibiotic cover. We aim to find the incidence of symptomatic urinary tract infections following MCUG done in children without antibiotic cover. A retrospective cross sectional study was conducted on 398 patients who underwent MCUG from January 2015 to January 2016. The median age was 24 months and here were 272 males and 126 females, with 102 of them being infants. Urine microscopy or culture was checked before performing the MCUG and only those without UTI were included in the study. Those with symptomatic and culture proven UTI within 2 weeks post-MCUG were defined as having post-procedure UTI (ppUTI). The incidence of post-procedure UTI was calculated and was compared with other studies. Data was entered in Microsoft Excel and analyzed using SPSS. Categorical variables were summarized as percentage and continuous variables were summarized as mean with standard deviation. Symptomatic procedure induced UTI were seen in only 3 of the 398 (0.75%) patients with a 95% CI of 0.02–0.008. Strict adherence to aseptic precautions while performing an MCUG and prompt initiation of appropriate therapy when indicated may help obviate the need for routine administration of pre procedure antibiotics before MCUG.

在没有抗生素覆盖的情况下接受排尿膀胱尿道造影的儿童术后症状性尿路感染的发生率

通常不建议在进出导管时使用预防性抗生素。然而，涉及类似导管插入术的程序，如排尿膀胱尿道造影 (MCUG) 和膀胱内压造影，正在预防性抗生素覆盖下进行。我们的目标是找出在没有抗生素覆盖的儿童中进行 MCUG 后症状性尿路感染的发生率。对 2015 年 1 月至 2016 年 1 月接受 MCUG 的 398 名患者进行了一项回顾性横断面研究。中位年龄为 24 个月，其中男性 272 人，女性 126 人，其中 102 人为婴儿。在进行 MCUG 之前检查了尿液显微镜检查或培养，只有那些没有 UTI 的人被纳入研究。那些在 MCUG 后 2 周内出现症状和培养证明 UTI 的人被定义为患有术后 UTI (ppUTI)。计算术后尿路感染的发生率，并与其他研究进行比较。将数据输入 Microsoft Excel 并使用 SPSS 进行分析。分类变量总结为百分比，连续变量总结为带有标准偏差的平均值。398 名 (0.75%) 患者中只有 3 名出现症状性手术诱发的 UTI，95% CI 为 0.02-0.008。在进行 MCUG 时严格遵守无菌预防措施，并在有指征时立即开始适当的治疗，这可能有助于避免在 MCUG 之前常规施用术前抗生素的需要。分类变量总结为百分比，连续变量总结为带有标准偏差的平均值。398 名 (0.75%) 患者中只有 3 名出现症状性手术诱发的 UTI，95% CI 为 0.02-0.008。在进行 MCUG 时严格遵守无菌预防措施，并在有指征时立即开始适当的治疗，这可能有助于避免在 MCUG 之前常规施用术前抗生素的需要。分类变量总结为百分比，连续变量总结为带有标准偏差的平均值。398 名 (0.75%) 患者中只有 3 名出现症状性手术诱发的 UTI，95% CI 为 0.02-0.008。在进行 MCUG 时严格遵守无菌预防措施，并在有指征时立即开始适当的治疗，这可能有助于避免在 MCUG 之前常规施用术前抗生素的需要。
