Urinary tract infection (UTI) is among the most frequent complications after urinary tract surgical procedures, mainly when catheter placement is necessary. Although the use of American cranberry has been related with a reduced risk of UTI, there is no study reporting the value of its prevention effect against catheter-associated urinary tract infections.
A prospective trial comparing UTI rate (positive urine culture) among 31 patients with double J catheter (JJ) and adding American cranberry (120 mg) in routine prophylactic therapy, and 31 patients with JJ catheter only receiving routine prophylactic therapy.
Regarding general characteristics of the populations no significant difference among groups have been found. Only significant differences have been observed when the variables "cranberry treatment" and "dwell time of JJ catheter" were related. "Dwell time of JJ catheter" was higher in patients with UTI (35.9 compared 28.5 days [P=.03]). UTI percentage was lower in cranberry supplemented patient group (12.9 compared to 38.7% [P=.04]).
We can conclude that American cranberry (120 mg) has an adjuvant effect in the prevention of UTI in patients with JJ catheter after surgery.
尿路感染（UTI）是尿路外科手术后最常见的并发症之一，尤其是在需要放置导尿管时。尽管食用美国蔓越莓与降低尿路感染风险有关，但尚无研究报告其预防导尿管相关尿路感染的效果价值。
一项前瞻性试验，比较31例双J导管（JJ）患者在常规预防性治疗中添加美国蔓越莓（120毫克）后的尿路感染率（尿培养阳性），以及31例仅接受常规预防性治疗的JJ导管患者的尿路感染率。
关于人群的一般特征，各组之间未发现显著差异。仅在变量“蔓越莓治疗”和“JJ导管留置时间”相关时观察到显著差异。UTI患者的“JJ导管留置时间”更长（35.9天对比28.5天[P = 0.03]）。补充蔓越莓的患者组UTI百分比更低（12.9%对比38.7%[P = 0.04]）。
我们可以得出结论，美国蔓越莓（120毫克）对预防术后JJ导管患者的UTI有辅助作用。
