Evaluation of Retrograde Intra Renal Surgery in the T-tilted Position

Condition(s) studied

Investigational drug(s) / intervention(s)

T-tilting of the patient during surgery: Patients will be placed at the T-Tilt position (15 degrees Trendelenburg and 15 degrees away from the surgical side kidney) during surgery.

standard lithotomy position: Patients will be placed in regular lithotomy position with operating table at 0 degrees of tilting.

Study summary

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

Eligibility

Primary outcome measure(s)

• stone free rate in the T-tilted position during surgery — the duration of the study of at least 6 months
  Follow up visits will be scheduled after 2 weeks; computed tomography urinary tract (CTUT) will be performed to identify stone-free rates and the procedure will be considered successful if no stones can be identified \>4mm.
