Minimal-access treatment for ureteropelvic junction (UPJ) obstruction is becoming increasingly complex. Is there still a place for the simple procedure of balloon dilatation? To examine the symptomatic and renographic results of patients at least 6 months after balloon disruption of an obstructed UPJ, we carried out a prospective audit of outcome as judged by DTPA renograms and clinical follow-up. The procedure has been performed on a total of 21 renal units (20 patients) with follow-up of 6 to 30 months (mean 22 months). Of these, 18 (86%) were asymptomatic at 3 months, although this success rate dropped to 17 (81%) by 6 months. Renographic split function improved in 11 renal units, and excretion improve in 14. Perioperative complications were few and associated with stent insertion. Three of the patients in whom the procedure failed went on to nephrectomy (14%); all had poor renal function (split <20%) at presentation. Although the quoted success rates are lower for endoluminal balloon rupture of stenosis treatment than open pyeloplasty, the former technique has significantly less morbidity. Our nephrectomy rate reflects our less than ideal early patient selection, and our balloon dilation technique is not recommended as a salvage procedure for patients in whom nephrectomy is inevitable. The learning curve is quick to climb, and this is a fundamentally simple procedure with medium-term results that remain encouraging.
