Prospective study to assist safty and efficieny of our technique of using peumatic lithotripsy with suction mini-pcnl.
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.
