Frequently Asked Questions
Does Dr. Nguyen treat newborns and very young infants?
Yes. Dr. Nguyen sees patients across all pediatric age groups, including newborns who have been diagnosed with urological anomalies prenatally or shortly after birth. Early evaluation is often important for conditions such as hydronephrosis or undescended testicles, so families are encouraged to schedule a consultation promptly when a concern is identified.
My child keeps having urinary tract infections. Can Dr. Nguyen help?
Recurrent urinary tract infections in children can indicate an underlying anatomical or functional issue, such as vesicoureteral reflux or bladder dysfunction. Dr. Nguyen can perform a thorough evaluation to identify the cause and recommend the most appropriate treatment, which may range from medication management to a minimally invasive procedure.
What should I expect at my child's first appointment with Dr. Nguyen?
The first visit typically involves a review of your child's medical history, a physical examination, and a discussion of any symptoms or prior test results. Dr. Nguyen may order imaging or additional testing based on the findings. The goal of that first appointment is to understand your child's specific situation and outline a clear path forward.
Does Dr. Nguyen perform surgery on children, and where are those procedures done?
Dr. Nguyen performs pediatric urological surgeries as part of her practice. Procedures are typically performed at a facility equipped for pediatric surgical care in the Orange, CA area. During your consultation, she will explain whether surgery is recommended, what the procedure involves, and what recovery looks like for your child.
Is bedwetting something Dr. Nguyen can evaluate and treat?
Yes. Bedwetting, known medically as nocturnal enuresis, is a common concern Dr. Nguyen addresses. She can assess whether the issue is related to bladder capacity, voiding habits, or another underlying factor. Treatment options range from behavioral strategies and bladder training to medication, depending on your child's age and circumstances.
