[The surgical treatment of staghorn nephrolithiasis in children and its effect on kidney function].

29 children with coral nephroliths were examined by dynamic nephroscintigraphy before surgery, after it and on postoperative month 6-24. The patients whose age ranged from 5 to 15 years underwent sectional nephrolithotomy (22 cases) or partial nephrolithotomy (7 cases). The findings led the authors to the following conclusions: the reduction in the renal function following sectional nephrolithotomy is inversely proportional to preoperative functional deficiency of the affected kidney; application of partial and sectional nephrolithotomy in children with coral and multiple nephroliths is justified only in case of contraindications to extracorporeal impulse lithotripsy; sectional nephrolithotomy in children with coral nephroliths is indicated in initial deficiency of the affected kidney function more than 50%.
