Mini-percutaneous nephrolithotomy for nephrolithiasis in pediatric patients

Objective:To explore the clinical effect of mini-percutaneous nephrolithotomy(MPCNL) for nephrolithiasis in pediatric patients.Methods:We retrospectively reviewed the clinical records of 58 cases of children who underwent percutaneous nephrolithotomy procedures for renal calcali from 2005 to 2007.Antegrade percutaneous access was obtained in all children and the tract was dilated to F16 that was used to remove stones.Results:A total of percutaneous nephrolithotomy procedures were performed.Average operative time was 67 minutes(range from 25 to 100) a 95% stone-free rate was achieved using percutaneous nephrolithotomy.No severe complications were noted.Conclusions:MPCNL is safe and effective for children and considered a viable option.
