Abstract
We attempted treatment of long-standing strictures of ureterovesical or ureterosigmoid anastomosis in 6 children by percutaneous balloon dilation. The 4 girls and 2 boys were between 2 and 19 years old (mean age 9 years) at the time of dilation. Obstruction occurred at the ureterosigmoid anastomosis in 3 patients and at the ureterovesical junction in 3. Obstruction was confirmed by diuresis renography, antegrade pyelography and pressure perfusion studies. An attempt at dilation was unsuccessful for 1 patient. For the remaining 5 patients the ureter has remained patent for a followup period of 7 to 18 months (mean 12 months).Percutaneous balloon dilation of established ureterointestinal and ureterovesical obstruction after failed surgical repair can be successful. The hospital stay is reduced and major surgery with its accompanying morbidity is avoided. If balloon dilation is unsuccessful, surgical repair remains an option. Balloon dilation should be seriously considered as an initial form of treatment in this group of patients.
