title: A novel drainage technique during micropercutaneous nephrolithotomy in pediatric patients: double angiocath.
abstract: Micropercutaneous nephrolithotomy (microperc) is a recently introduced percutaneous nephrolithotomy (PNL) technique that has the smallest tract size. The absence of an amplatz sheath during the microperc technique is a fundamental difference that distinguishes it from all other types of PNL (standard, mini, ultramini). Increasing of the intrarenal pelvic pressure (IPP) was demonstrated by the authors in adult patients but this problem may be even more serious in pediatric patients. Previously, the authors defined the use of a 14 gauge angiocath needle and sheath (microsheath) during microperc surgery for pediatric patient to reduce the IPP. In this novel technique, a second angiocath is used to access the renal collecting system to drain fluid during surgery. This technique is more effective in reducing IPP during microperc, especially in pediatric patients.
