184 29 th CONGRESS OF THE ESPU 12:28–12:31 S25-3 (PP) COMBINED USE OF FLEXIBLE URETEROSCOPY WITH MICRO-PERCUTANEOUS NEPHROLITHOTOMY IN PEDIATRIC MULTIPLE KIDNEY STONES: A SINGLE TERTIARY CENTER EXPERIENCE IN CHINA Wenying WANG, Jun LI and Ye TIAN Beijing Friendship Hospital, Capital Medical University, Urology, Beijing, CHINA 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. 12:31–12:34 S25-4 (PP) PCNL IN PEDIATRIC PATIENTS WITH DERANGED RENAL FUNCTIONS: SAFETY AND EFFICACY Sherjeel SAULAT, M. Murtaza AZAD, Anees SOOMRO and Syed Saeed QADRI Tabba Kidney Institute, Paediatric Urology, Karachi, PAKISTAN 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.
