PURPOSE
This study is to investigate the effectiveness and reliability of combined use of flexible ureteroscopic
lithotripsy (FUL) with micro-percutaneous nephrolithotomy (micro-PNL) for the management of
pediatric multiple kidney stones with extensive distribution.
MATERIAL AND METHODS
In total, 21 pediatric patients with multiple renal calculi between Feb 2016 and May 2017 were
selected for FUL combined with micro-PNL. The cases included 13 boys and 8 girls; patients' mean
age was 3.8 years (range 1–8 years); and The maximum diameter of the stones ranged from 1.0 to
1.5 cm. FUL was first performed in the lithotomy position to fragment stones that were located in
the renal pelvis, upper and mid renal calyx. Patients were then moved to a prone position and
micro-PNL was performed to treat lower pole stones which could not be touched by flexible uret-
eroscope during FUL. Percutaneous renal access to the lower calyx was achieved using a 4.8F "all
seeing needle" with ultrasound guidance, and stone fragmentation was performed with a 200-um
holmium laser in different setting to achieve dusting of fragments of 1–2 mm according to stone
disintegration.
RESULTS
All the pediatric patients with complex renal calculi underwent a combined FURS and micro-PNL
successfully. The one-phase stone free rate (SFR) was 85.7 % (18/21). According to the modified
Clavien classification, Grade 1, Grade 2, Grade 3b postoperative complications occurred in 6, 1,
and 1 patient respectively. The mean hemoglobin drop was 0.4g/dl (0.1–0.8g/dl). The average
hospital stay was 3 days (range, 2–5 days).
CONCLUSIONS
Combined FURS and micro-PNL is a safe, effective, minimally invasive operation to remove com-
plex renal calculi in children in selected cases.

PURPOSE
The purpose of this study is to assess the effectiveness of PCNL in children with deranged renal
functions and to compare the safety and efficacy of PCNL in these patients with those having
normal renal functions.
