Implementation of Ultramini Percutaneous Nephrolithotomy for Treatment of 2–3 cm Kidney Stones: A Preliminary Report

Abstract

Implementation of UMP for the treatment of patients with renal stones 2-3 cm is feasible and safe. The procedure is less invasive and has a faster recovery period. Intraoperative retrograde UAS decreases intrarenal pressure, facilitates removal of stone fragments, and also allows simultaneous RIRS for stones in an inaccessible calix.
