All the demographics, surgical data and post-operative information were obtained to identify the stone free rates and complications.</span></span></p> <p style="text-align: justify;"><span style="font-size:14px;"><span style="font-family:times new roman;"><span style="color:#008080;"><strong>Results:</strong></span> In a total, 119(56.4%) cases of 211 patients who underwent Percutaneous Nephrolithotomy in our study were male and 92(43.6%) cases were female. The mean age of participants was 137.15&plusmn;60.11 months (range: 9-204). The most common presenting symptom was pain (62.6%). The mean stone burden was 23.5 &plusmn; 9.68mm and the mean operative time was 109.95&plusmn;37.1 min. Overall, stone clearance rate was 73.9% after single PNL. Among those patients who had renal malformation, the stone free rate was (13/19) 68.4% for PCNL. The postoperative complication rate was 5/47 (10.6%) during all procedures and there were no major operative or postoperative complications.</span></span></p> <p style="text-align: justify;"><span style="font-size:14px;"><span style="font-family:times new roman;"><span style="color:#008080;"><strong>Conclusions:</strong> </span>According to the findings, pediatric PCNL with the acceptable stone free rates could be considered as a safe and effective procedure among children with complex stones and renal malformation.</span></span></p> Percutaneous Nephrolithotomy, Nephrolithiasis, Pediatrics, Complications 164 170 http://caspianjp.ir/browse.php?a_code=A-10-45-1&slc_lang=en&sid=1 Akbar Nouralizadeh 10031947532846001017 10031947532846001017 No Labbafinejad Hospital, Shahid-Beheshti University of Medical Sciences, Tehran, Iran.
