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...

Pelvic kidney stones remain a unique challenge to the endourologists. Treatment options include open surgery, extracorporeal shockwave lithotripsy, percutaneous nephrolithotomy (PNL), retrograde intrarenal surgery, and laparoscopy assisted PNL (LA-PNL). As a minimal invasive option, LA-PNL can decrease the risk for bowel and major vessel injury. Here, we describe our experience using the LA-PNL procedures with different combinations, to treat kidney stones in multiple patients with a pelvic ectopic kidney (PEK)...
