Abstract

Purpose

We report our initial experience of MINI percutaneous nephrolithotomy (PCNL) in a pediatric population using a miniature nephroscope through a 16F metal access sheath.

Methods

All pediatric patients who underwent PCNL from August 2007 to September 2010 using a 14F miniature nephroscope through a 16F metal access sheath for renal stone extraction were evaluated. Patients’ demographic details, procedural information, and posttreatment outcomes were prospectively documented.

Results

A total of 23 MINI PCNLs were performed on 23 kidneys of 12 patients whose ages ranged from 1.6 to 14.6 years. The median stone burden was 3.44 cm², and there were 11 “Staghorn” stones. The procedure was primary via a single puncture in 19 kidneys and secondary using a preexisting nephrostomy tract in 4 kidneys. Access was successful in all primary and two secondary cases, for a total of success rate of 91.3 %. Stones were fragmented using a Holmium laser and/or lithoclast, and fragments were irrigated or sequentially removed by various stone grasping devices. The mean procedural X-ray screening time and total stone extraction period were 4.5 and 109.4 min, respectively. The primary stone free rate was 83.6 %, which increased to 90.5 % after treating the residual fragments. Postoperative hydrothorax developed in one patient, which required a chest drain. Symptoms of chest infection and positive urine culture were detected in one and two patients, respectively.

Conclusions

Our initial experience supports previous reports that MINI PCNL is safe and effective for the management of renal stones in children.
