Tubeless Mini_PerctaneousNephrolithotomy in Pediatric Population

Abstract

Renal stone disease in children is uncommon and poses a clinical management dilemma due tothe size of the urinary tract and risk of recurrence. The majority of renal stones are due to metabolic disorders or infection with a consequently high lifetime risk of recurrence. The percutaneous nephrolithotomy PNL procedure is simply based on creation of a proper percutaneous renal access, through the most appropriate part of the kidney (lower calyx in most cases),dilation of this tract, and fragmentation and removal of the stone fragments using the nephroscope through the access heath. Although different sizes of nephroscopes are used according to the tract size, the conventional or standard percutaneous nephrolithotomy procedure is generally performed through the 26–30 Fr access tract. Jackman etal.defined the mini-perctechnique in infants and preschool children. He used aminiaturized nephroscope through the 11 Fr peel-away vascular sheath. Today, the mini-perc or minimally invasive PNL is generally defined for the percutaneous nephrolithotomy PNL procedure performed through the access tract18 Fr. Besides the mini-perc and standard PNL. The aim of this work is to evaluate safety and efficacy of tubeless mini–percutaneous nephrolithotomy in comparison to standard mini-percutaneous nephrolithotomy with nephrostomy tube in management of pediatric renal stones. This prospective stud had carried out on 20 pediatric patients divided into 2 groups: - Group 1 includes 10 pediatric patients who underwent standard mini_ percutaneous nephrolithotomywith nephrostomy tube. - Group 2 includes 10 pediatric patients who underwent tubeless mini_percutaneous nephrolithotomy .
