The long-term results of Anderson-Hynes pyeloplasty.
OBJECTIVE
To examine the durability of open pyeloplasty for pelvi-ureteric junction obstruction.


METHODS
The records of 56 Anderson-Hynes pyeloplasties undertaken by two surgeons between 1981 and 1994 were examined. Attempts were made to trace all patients and for them to undergo diuretic renography to examine the current status of the operated renal unit.


RESULTS
In all, 41 evaluable patients were identified; 24 agreed to return for reassessment. The mean (range) time from surgery was 10.6 (6-19) years. The results showed an improvement over the preoperative split renal function in 19 patients (79%) and an improvement in drainage in 23 (96%).


CONCLUSIONS
The Anderson-Hynes pyeloplasty is an excellent procedure for treating pelvi-ureteric junction obstruction, and produces a lasting improvement in function and drainage in most patients. It is the 'gold standard' against which newer techniques should be compared.
