Urinary NGF as A Biomarker for Acute Bacterial Cystitis

Summary

This study will enroll 30 female patients with the first time urinary tract infection (UTI), 30 female patients with recurrent UTI and 10 female without any prior history of UTI or urinary tract pathology will be invited to serve as the controls. Urine samples will be collected in the patients at baseline, 7 days after antibiotics treatment, and 2 weeks, 4 weeks, 8 weeks, and 12 weeks. Urinalysis will be performed at each visit and urine culture will be performed at baseline and at the 2 weeks and 3 months visits. Urine samples at baseline and 3 months will be collected from the controls for comparison.
