Ureteropelvic Junction Obstruction as a Cause for Intermittent Abdominal Pain in Children

Two or three times each year children are seen by the Urology Service at Children's Hospital, Washington, DC, who have a history of intermittent, severe midabdominal pain associated with vomiting due to intermittent ureteropelvic junction obstruction. These symptoms may have been on-going for years. The following case history serves as a typical example. CASE REPORT A 6-years-old boy was referred to the Urology Service from the Gastrointestinal Service where he had been sent by his primary physician. He had a 1-year history of episodic abdominal pain occurring one to two times per month initially, but becoming more frequent during the past few months.
