OBJECTIVE: To present the safety and efficacy of totally ultrasound-guided percutaneous nephrolithotomy (PCNL) for managing of urinary stones in pediatric patients.
MATERIAL AND METHODS: Ten children with mean age of 5.4 (3-11) years underwent totally ultrasound-guided PCNL from March 2013 to November 2013. Pyelocalyceal system was punctured in prone position by using ultrasonographic guidance and the tract was dilated using single shot dilation technique. All steps of renal access were done by using ultrasonography and no fluoroscopy was used. PCNL in all cases was done by using adult instruments.
RESULTS: The mean stone size was 28.9±6.7mm (range 17-35). The mean access time to stone was 4.45±2.25 min (range 3-10). The mean nephroscopic time was 45.9±17 min (range 20-80). The stone free rate was 83%. Mean hospital stay of patients was 3 days (range 2-5 days). No major complications were happened. Only one patient required ureteral stent insertion because of urinary leakage from nephrostomy tract.
CONCLUSION: Our experience with totally ultrasonography-guided PCNL using adult size instruments in children revealed proper results and acceptable complications compared with the standard technique of PCNL. Likewise, this alternative method has the advantage of preventing radiation hazards.
