title: Pyeloplasty in infants and children with particular reference to the method of drainage post-operatively.
abstract: Sixty-three consecutive Anderson-Hynes pyeloplasties in infants and children have been reviewed with particular reference to any influence the method of drainage might have on the post-operative course and the final radiological result. Extra-anastomotic drainage usually with a sump drain, was used in 40 cases and pyelostomy drainage in 23 cases. Fewer post-operative complications were encountered in the former group. The final radiological result was not influenced by the method of drainage except that, in patients under 2 years of age, those with pyelostomy drainage fared rather better. It is concluded that (a) extra-anastomotic sump drainage is the method of choice following pyeloplasty in children over 2 years of age, and (b) in infants under 2 years of age pyelostomy drainage probably should be combined with a trans-anastomotic splint.
