Detailed Description

anew techniqe was designed to improve the results of pneumatic lithotripsy in suction mini-PCNL by:

  1. Customize our instrument to be suitable for a short 12 Fr nephroscope.
  2. using certain measures to avoid stone migration during pneumatic disintegration.

By fixing stones during disintegration and suction.

  • Our puncture strategy was planned to prevent stone migration.
  • Use a suction sheath to gently fix the stone between the tip of the sheath and the inner wall of the kidney and disintegrate it from inside the sheath.
  • The dormai basket was used to fix the stone in front of the sheath in difficult situations.

The investigators will assess disintegration time as the primary endpoint and stone-free rate and complications as secondary endpoints.
