Sixty-seven patients, aged 3–71 years, with primary hydronephrosis were operated at our department during a 5-year period. All patients had Anderson-Hynes pyeloplasty. The primary clinical result of surgery was excellent in 63 patients (94%). Of the patients with reduced renographic uptake fraction preoperatively, 38% had a significant gain 6 months after reconstruction, while only 1 patient had a reduction. There was no correlation between the outcome of reconstruction and preoperative history, degree of hydronephrosis on IVP, preoperative functional share on renography or the peroperative finding of aberrant vessels compressing the ureter. It was concluded that surgery should be undertaken on rather wide indications as reconstruction leads to stable or improved renal function regardless of preoperative symptoms or diagnostic findings.
