Recent years have seen innovations in working armamentarium of percutaneous nephrolithotomy (PCNL) leading to development of novel modifications such as miniperc, ultra miniperc, and microperc. Amongst these microperc appears to be least invasive and various authors, off late, have reported their experience with the technique. Literature on microperc was reviewed by a MEDLINE/PubMed search with articles in the English language since 2011 in published peer-reviewed journals. Articles comprised of case series, comparative, and noncomparative studies...

Miniaturization in percutaneous surgery has seen its zenith in microperc. Technological advances have enabled us to treat renal lithiasis through a 4.8 Ch. caliper percutaneous access. According to published literature, the technique is reproducible and when applied to small and medium size renal lithiasis has a high success rate keepin a low complication rate. Its main advantage is the absence of tract dilatation, diminishing the bleeding risk inherent to percutaneous access, postoperative pain and hospital stay...

BACKGROUND: Percutaneous nephrolithotomy (PCNL) has been adopted for pyelo-calyceal stones treatment in pediatric patients, starting from the 90's. Very recently, miniaturization of endoscopic instruments allowed less invasive procedures with low complication rate. We reviewed our experience on upper tract stone treatment utilizing two different percutaneous accesses, focusing on the recent new miniaturized devices offered for pediatric renal stones. METHODS: Patients presenting upper tract urinary stones observed from January 2011 to December 2015 and treated by percutaneous renal access were prospectively evaluated: age, sex, metabolic issues, associated abnormalities, treatment modalities, hospital stay and complication rate were recorded in a specific database...

BACKGROUND: Urinary stones disease is becoming more common not only in adults but also in children. Most cases are resolved with extracorporeal shock wave lithotripsy, but miniaturization of endoscopes has increased the use of ureteroscopy in resolving ureteral stones, most notably in children. CASE PRESENTATION: This presentation focuses on two cases of microureteroscopy. In both cases, the presence of lithiasis in the pelvic ureter was suspected to be the cause of ureter hydronephrosis, and a microureteroscopy was performed for treatment purposes...

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...

Percutaneous nephrolithotomy is accepted as the standard management approach for kidney stones that are either refractory to extracorporeal shock wave lithotripsy or are >2 cm in diameter. The recently developed micro-percutaneous nephrolithotomy (microperc) technique provides intrarenal access under full vision using an optic instrument with a smaller calibration. A lesser amount of bleeding has been reported with the use of this method. Here we present a case of a bleeding complication on postoperative day 15 after a microperc procedure used to treat a left kidney stone...
