Retrograde balloon dilatation for pelviureteric junction obstruction.
A total of 49 retrograde balloon dilatations for pelviureteric junction (PUJ) obstruction were carried out on 43 pelviureteric junctions in 42 patients from 1986 to 1991. The majority (34/43) were performed as primary treatment for PUJ obstruction, with 9 patients having a history of previous open pyeloplasty. Follow-up ranged from 3 months to 4 years (mean 18 months). Clinical improvement, as assessed by absence of symptoms, was seen in 34 cases (80%). There was either no change or an improvement in renographic findings (t1/2 time and/or split function) in 40 patients (93%). Of the 9 patients who were undergoing secondary treatment, 5 showed clinical improvement and 8 showed no change or renographic improvement. Nine patients required 12 further procedures, of which 5 were interval nephrectomy. Balloon pyelolysis is a simple procedure with good results over a 4-year follow-up period. It is less effective for the treatment of secondary pelviureteric junction obstruction. It has a low morbidity and no mortality, involves a short hospital stay and allows an immediate return to full activity. It is therefore an attractive alternative to open pyeloplasty as first-line treatment for PUJ obstruction.
