Hi. Thanks for writing in. Frequency of sexual intercourse is the strongest predictor of recurrent urinary tract infections in patients presenting with recurrent dysuria and can reach the kidneys. Regular ultrasound scans are important in assessing the effect of repeated infections on the kidneys. Women with recurrent symptomatic urinary tract infections can be treated with continuous or sexual intercourse prophylactic antibiotics; other treatment options include self-started antibiotics, cranberry products, and behavioral modification. Patients at risk of complicated urinary tract infections are best managed with broad-spectrum antibiotics initially, urine culture to guide subsequent therapy, and renal imaging studies if structural abnormalities are suspected.
