PURPOSE:

To present the safety and efficacy of totally ultrasonography-guided percutaneous nephrolithotomy (PCNL) for managing urinary stones in pediatric patients.

PATIENTS AND METHODS:

Ten children with a mean age of 5.4 (3-11) years underwent totally ultrasonography-guided PCNL from March 2013 to November 2013. The pyelocaliceal system was punctured with the patient in the prone position by using ultrasonographic guidance, and the tract was dilated using a single-shot dilation technique. All steps of renal access were performed by using ultrasonography; no fluoroscopy was used. PCNL in all cases was performed by using adult instruments.

RESULTS:

The mean stone size was 28.9±6.7 mm (range 17-35 mm). The mean access time to stone was 4.45±2.25 minutes (range 3-10 min). The mean nephroscopic time was 45.9±17 minutes (range 20-80 min). 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 needed ureteral stent insertion because of urinary leakage from the 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 hazard.
