Review Question - QID 210630

An otherwise healthy 6-year-old boy presents for a follow-up visit to his pediatrician's office for persistent nocturnal enuresis. He has never been dry at night and throughout the last year the pediatrician has seen him multiple times for this issue. He and his family have tried not drinking liquids 2 hours before bed, bed wetting alarms, and a reward sticker chart with limited success. His 2 older brothers had nocturnal enuresis that resolved on its own when they were 8 years of age, but the patient often sleeps over at a friend's house and is very bothered by this problem. He has 1 soft stool a day, denies abdominal pain, dysuria, or frequency, and has been continent during the day since 3 years of age. He has a completely normal physical exam, urinalysis, and basic metabolic panel. What is the next best step in management?
