PEDIATRIC URETEROPELVIC JUNCTION OBSTRUCTION TREATED WITH RETROGRADE ENDOPYELOTOMY

Objectives. To determine the feasibility of retrograde endopyelotomy in the management of pediatric ureteropelvic junction (UPJ) obstruction. Methods. We treated 2 boys aged 4 and 6 years with the Acucise endopyelotomy device for symptomatic ureteropelvic junction obstruction. The Acucise device was placed over a Lunderquist guide wire with fluoroscopic guidance only and routine Double J catheters were left in situ for 6 weeks after the procedure. The morbidity of the treatment and the short-term outcome were assessed. Results. There were no acute complications and short-term follow-up results were satisfactory as determined by intravenous urography and diuretic renography. Conclusions. Ureteropelvic junction obstruction in children may be treated by retrograde endopyelotomy with the Acucise device. The principal potential advantage of this procedure is reduced morbidity. Our findings suggest that further evaluation is warranted.
