Summary

The investigator will compare between holmium laser setting during miniPCNL for renal stones as regard safety \& efficacy

Conditions

  • Renal Stones
  • Renal Calculi > 2 cm

Interventions

PROCEDURE

mini percutaneous nephrolithotomy

Under fluoroscopic guidance, an 18G Chiba needle is used to access a posterior calyx or the appropriate target calyx). Contrast confirms the collecting system entry. Dilation is performed, typically up to 14-20 Fr. A mini-nephroscope (15 Fr) is inserted through an appropriate sheath. Irrigation is maintained using gravity or low-pressure systems. Holmium: YAG laser is used for lithotripsy. high pulse power will be capped at 40 W, while low pulse power settings will remain between 10-20 W. Fragments are evacuated via vacuum cleaner effect or basket through the sheath.
