Outcome of early experience of Miniperc technique in pediatric age group

BACKGROUND: The aim of this study is to report our experience with the Miniperc technique for treatment of renal stone in pediatric age group. MATERIALS AND METHODS: From August 2012 to January 2015, 34 patients aged <15 years with renal stones <3 cm underwent Miniperc technique were included in our study. The procedure was done through 14 Fr sheath using 8/9.8 Fr semi-rigid ureteroscope, holmium laser, and pneumatic lithotriptor for stone fragmentation. Stone-free rate (SFR), operative time, hospital stay, and complication rate were evaluated. RESULTS: A total of 34 Miniperc techniques were performed on children with a mean age of 8.8 ± 3.7 years. Stone size varied from 18 to 30 mm (mean 23 mm). Mean operative time was 50 min. The mean hospital stay was 48±12 hours. The overall SFR was 82.4% which increased after secondary procedures to 94%. Two postoperative complications recorded in the form of sepsis and bleeding that required no blood transfusion. CONCLUSION: Our initial experience concluded that Miniperc technique is a safe and effective treatment option for renal stones in pediatric population.
