Abstract
OBJECTIVE: To evaluate the functional outcome of anatrophic nephrolithotomy in children. PATIENTS AND METHODS: All children undergoing anatrophic nephrolithotomy for complex branching and multiple renal calculi over an 11-year period were studied prospectively. Demographic data, treatment details and outcome, as assessed by X-ray, ultrasonography and isotope studies, were recorded. Anatrophic nephrolithotomy was carried out with surface cooling of the kidney followed by nephrostomy drainage for 5-7 days. RESULTS: Nine children (median age 4 years, range 7 months to 9 years) underwent anatrophic nephrolithotomy. Predisposing factors included urinary tract infection (by Proteus mirabilis) in all and hyper-calciuria in two children. The median (range) total ischaemic time at operation was 25 (15-40) min and the operative duration 150 (120-200) min. Three children required a blood transfusion. Stone clearance was incomplete in one child. There was no recurrent stone formation after a long-term follow-up (median 32 months, range 14-107) in the other patients. Isotope studies showed impaired split renal function (<40%) in six children before surgery; there was a significant decline (>5%) in divided function in five children (range 6-16%) after surgery. CONCLUSION: Anatrophic nephrolithotomy is an effective means of rendering children with branching calculi stone-free, but this study suggests that it leads to some further parenchymal damage.
