Laparoscopic pyeloplasty for Children with pelvic ure- teric junction obstruction: An institutional experience

Abstract

To give a report of 36 consecutive children who underwent laparoscopic Anderson-Hynes dismembered pyeloplasty by a single lead surgeon.The diagnosis of pelviureteric junction obstruction was firmly established in all patients based on history, clinical examination, renal sonography and scintigraphy. Transperitoneal laparoscopic Anderson-Hynes pyeloplasty was performed in all the patients. Age at surgery, duration of operation, complications and outcome were documented. Children were followed up for symptoms, and diuretics renography was repeated at 3 months.A total of 36 children 5 months to 11 years (25 boys and 11 girls) under- went laparoscopic Anderson- Hynes pyeloplasty over a 4- year period. Mean age at surgery was 41 months (range 7 to 144). Seventeen (47%) cases were antenatally diagnosed. The mean operating time was 247 min. No patient required blood transfusion, and there were no intra-operative complications. The mean postoperative hospital stay was 5.8 days. There were 7 postoperative complications including urinary tract infection (n=6) and shoulder pain (n=1). The symptoms improved in 32(89%) children. There were 3 conversions, 2 due to non rotated kidney and one due to double right moiety. One child had failed pyeloplasty with deteriorating renal function. He had a redo open pyeloplasty. The mean split renal function before surgery and at follow up diuretic scan was 36.2 vs 42.1, P=0.001. The mean follow up period was 30 months.Laparoscopic Anderson-Hynes pyeloplasty is safe and effective in the management of children with pelvi-ureteric junction obstruction.
