Abstract

This study aimed to investigate the effectiveness and reliability of micro-percutaneous nephrolithotomy (micro-PNL) for the management of kidney stones in pediatric patients. This retrospective study included 24 infants that underwent micro-PNL for renal stones between March 2012 and April 2015. The inclusion criteria included: age younger than 2 years, stone size <20 mm, absence of urinary tract malformations and active infection, and no coagulopathy. Stone-free rates were assessed one month postoperatively by ultrasonography (USG) and kidneys, ureters, bladder (KUB) radiography. Complications were classified according to the Clavien classification system. The mean age of the patients was 15.8 ± 7.8 months (range, 8–23) and the mean stone size was 13.5 ± 3.84 mm. Intra-renal access was achieved using USG in 11 patients and KUB fluoroscopy in 13 patients. The operation time and fluoroscopic screening time were 53.7 ± 10.35 and 1.4 ± 0.9 min, respectively. The mean hospital stay was 2.5 ± 0.8 days, and the mean drop in the hemoglobin level was 0.51 ± 0.34 g/dL. Bleeding requiring blood transfusion was not observed. A ureteral J stent was implanted perioperatively in four patients because of stone burden. Four patients complained of postoperative renal colic (Clavien grade 1) and postoperative fever was observed in two patients. Definitive success rates were as follows: the stone-free rate was 83.3 % (n = 20) and residual fragments were observed in four patients.
