Urology Services for Children

Text or call: (702) 728-5686

Children are not just small adults.  They cannot always say what is bothering them.  They cannot always answer medical questions, and are not always able to be patient and cooperative during a medical examination.  Dr. Hwang is specially trained to examine and treat children in a way that makes them relaxed and cooperative.  We use equipment specially designed for children and we arrange and decorate our office with children in mind. We have toys, music, and reading materials for children.  This helps create a comfortable and nonthreatening environment for your child.

If your pediatrician suggests that your child see Dr. Hwang, a board-certified pediatric urologist, you can be assured that he has the widest range of treatment options, the most extensive and comprehensive training, and the greatest expertise in dealing with children and in treating children’s genital and urinary tract disorders.

Office Procedures

We perform certain procedures in the office when appropriate.  The advantages of being able to do these procedures in the office include the avoidance of general anesthesia for the child, less lost time from work for parents, and significant cost savings for the family.

Please understand that the procedure may not be done on the same day of the office visit as the child may need some preparation at home.

Surgical Procedures done in a surgical facility

Most surgical procedures in children are performed under general anesthesia at an appropriate age when the child can easily recover from the anesthesia.  In this setting, the child will not experience any discomfort during the procedure, as any potentially painful procedure, including insertion of the IV, are only done after the child has gone to sleep with medication given through a mask.  When appropriate, the child will be given a regional anesthetic block to keep the surgical area from hurting for another 6 to 8 hours.

Commonly, these are done on an outpatient basis, which means the child goes home the same day of surgery.  More complicated cases, such as reconstructive surgeries on the ureter and bladder, typically need 1-2 nights of recovery and observation in the hospital.

If your child is having surgery under general anesthesia, it is imperative that pre-operative instructions are followed carefully.  If you have any questions regarding such instructions, please do not hesitate to call our office.
