Evaluation of Retrograde Intra Renal Surgery in the T-tilted Position
Evaluation of the T-tilted Position in Retrograde Intrarenal Surgery Using Flexible and Navigable Suction Access Sheath.

INTERVENTIONAL
Conditions
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
Inclusion Criteria1
- All patients above the age of 16 years of either sex who did not have a pre-existing ureteral stent presented to the Urology clinic in our university hospitals with kidney stones with size up to 2.5cm (estimated by CTUT as the greatest dimension or the summation of the greatest dimensions).
Exclusion Criteria4
- Previous open renal surgery or renal trauma.
- Patients with renal anomalies.
- Patients with untreated or active UTI.
- Patients who suffer from medical conditions that preclude the application of Trendelenburg position (lung disease, congestive heart failure).

Interventions
Patients will be placed at the T-Tilt position (15 degrees Trendelenburg and 15 degrees away from the surgical side kidney) during surgery.
Patients will be placed in regular lithotomy position with operating table at 0 degrees of tilting.
