About this study

To evaluate the effect of the T-tilted position on the stone-free rate compared to the standard lithotomy position in retrograde intrarenal surgeries. Common positions include the Trendelenburg position, where the patient is tilted head-down to help gravity move stones from the upper calyces to the renal pelvis, and the modified lateral decubitus position, which improves access to the lower renal poles. A more recent approach, the modified T-tilt position, combines a slight Trendelenburg tilt with lateral positioning, offering optimal access to both the upper and lower calyces while maintaining patient comfort
