title: Long-term follow-up of patients with hydronephrosis treated by Anderson-Hynes pyeloplasty.
abstract: A series of 21 patients with hydronephrosis (mean age 37 years) underwent an Anderson-Hynes pyeloplasty; a nephrostomy catheter was not used routinely. One patient developed urinary leakage post-operatively but this ceased following insertion of a ureteric catheter. Assessment was carried out after a mean observation time of 85 months. Clinical examination, laboratory investigations, urography and renography were performed pre-operatively and at follow-up. There was no evidence of stones or stenosis in the pelvis. Patients operated upon before the age of 30 years showed improved renal function. All patients had symptoms pre-operatively but only one had symptoms post-operatively. It was concluded that the results of surgical intervention in hydronephrosis are excellent, especially in patients aged less than 30 years.
