Abstract

The micropercutaneous nephrolithotomy (microperc) is the ultimate technological advance in the treatment of urolithiasis. We describe a variation of the original technique and it´s additional advantages to this surgical approach. A woman of 67 years old with a body mass index of 28.6 kg/ m2 with a stone of 25 x 20 mm in the left renal pelvis was positioned in Valdivia - Galdakao decubitus. After retrograde pielography, it was placed a ureteral access sheath 11/13 F to the level of the ureteropelvic junction. The puncture of the kidney was performed under fluoroscopic guidance. The stone was disintegrated with holmium laser. At the end of the procedure it was performed a flexible nephroscopy to comprove the stone free status.
