Summary

This trial will compare the effectiveness of cranberry capsules and nitrofurantoin in preventing urinary tract infections after urogynecologic surgery.

Who is the study for?
This trial is for English-speaking women aged 18 or older who are planning surgery for pelvic organ prolapse or urinary incontinence. It's not suitable for pregnant women, those dependent on catheterization before surgery, with a low kidney function (creatinine clearance <60 mL/min), recurrent UTIs, congenital anomalies, or allergies to cranberries or nitrofurantoin.
What is being tested?
The study compares the use of cranberry capsules versus nitrofurantoin (an antibiotic) to prevent urinary tract infections after urogynecologic surgery. Participants will be randomly assigned to one of these treatments in a double-blind setup where neither they nor the researchers know who gets which treatment.
What are the potential side effects?
Cranberry capsules may cause mild stomach upset and diarrhea. Nitrofurantoin can lead to side effects like nausea, headache, dizziness, and rarely lung problems or liver issues.
