Long‐term Follow‐up of Patients with Hydronephrosis Treated by Anderson‐Hynes Pyeloplasty

Summary— 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.
