RIRS With Tip Flexible Pressure-controlling Ureteral Access Sheath Versus Mini PCNLfor Kidney Stones

Study Overview: This study looks at two ways to treat kidney stones that are 2-3 cm in size. One method is called RIRS, which stands for Retrograde Intrarenal Stone Surgery. It uses a special tool called a ureteral access sheath (UAS) to help remove stones from the kidney. The other method is mini PCNL, which stands for percutaneous nephrolithotripsy, a technique that involves making a small cut in the skin to reach the kidney stone.

• Duration & Visits: The study is observational, which means doctors will watch and record data during the treatment.
• Eligibility: You must be 18 or older with a kidney stone size of 2-3 cm.
• Risks & Benefits: The study compares safety and effectiveness, so it may help find better treatment for kidney stones.

Note: You cannot join if you have unusual kidney anatomy or an uncontrolled urinary tract infection. If you meet the requirements, you may help doctors learn more about which treatment works best for certain kidney stones.
