Terri, I am a Physician Assistant in a Pediatric Urology office and manage most of the children with bedwetting. We frequently recommend alarms. However, I noticed reference to your child's constipation and wanted to point out that this can be a contributor to wetting as well as daytime problems if they exist. Often we see children with such significant constipation that there is no room for their bladder in the pelvis. Also, constipation can be a sign of excessive sphincter holding that can encompass the bladder and bowel sphincters. In turn this can cause increased resistance to voiding and thickening of the bladder muscle which may result in decreased bladder volume. I am glad you have had success with the nights. If anything written here elicits further questions, please write to tgast@childrensurology.net
