Published in American Journal of Obstetrics and Gynecology
Methodology
Randomized, double-blind, placebo-controlled trial of cranberry juice capsules twice daily for 6 weeks after elective gynaecological surgery with catheterisation
Key Findings
UTI occurred in 19% of the cranberry group versus 38% of placebo, roughly halving post-operative UTI risk.
Conclusions
Cranberry capsules reduce UTI risk after catheterised gynaecological surgery.
Limitations
Single hospital; specific surgical population; capsule dose equivalent to two 8-ounce juice servings may not match other products.
Supplements Studied
The occurrence of UTI was significantly lower in the cranberry treatment group compared with the placebo group (15 of 80 [19%]).
