[Pyeloplasty for pyelo-ureteric junction syndrome in children: lombo-assisted procedure versus lombotomy]

Abstract

Surgical treatment of pyelo-ureteric junction syndromes was classically at the child's, a pyeloplasty by posterior way or by lombotomy. For several years, assisted video techniques are proposed for this gesture. The purpose of our study was to compare the lombo-assisted pyeloplasty procedure with the lombotomy procedure, within the framework of this coverage. We made a retrospective study of procedures performed from January 2000 to December 2005, based on a file review of children operated for pyelo-ureteric junction syndrome. Children under the age of 2 years were excluded. Fifty-two children were divided in 2 groups: group 1: 24 children, 7 girls and 17 boys, average age of 86 months (extremes: 27-172) benefited from a lombo-assisted pyeloplasty. Group 2: 28 children, 12 girls and 16 boys, average age of 69 months (extremes: 24-129) benefited from a pyeloplasty by lombotomy. Operating times were significantly shorter in opened surgery than with the lombo-assisted procedure. There was no significant difference in terms of per- or post-operating complication, use of analgesic and hospitalization duration. On the other hand, the lombo-assisted procedure provided the same undisputable aesthetic benefit and the same muscular preservation than pure lomboscopy procedure. As a consequence, this procedure could be set up at no risk for the patient, even if it had lead to longer operating times. However, operating times stayed shorter than with the pure lomboscopy or the celioscopy procedures, compared to the literature.
