Clinical Efficacy of Mini-PCNLversus RIRS for the Management of Upper Urinary Tract Calculus (1-2.5 cm)

"Mini-PCNL~. A 12 Fr rigid nephroscope and a Holmium:YAG laser as energy source was used for surgery Percutaneous renal puncture was achieved with an 18 Ga needle after displaying renal collecting system with contrast material. and tract dilatation was achieved using Amplatz dilators up to 16-18 Fr according to patient age"

RIRS Technique the 9.5 Fr ureteral access sheath (UAS). UAS was inserted over the guide wire under fluoroscopy control. A flexible ureteroscope was passed through the UAS. If the UAS did not pass over the guide wire, the investigator moved the flexible ureteroscopy over the guide wire without access sheat
