Evaluating a new patient position for kidney stone surgery
Evaluation of the T-tilted Position in Retrograde Intrarenal Surgery Using Flexible and Navigable Suction Access Sheath.
NA · Ain Shams University · NCT06860113
This study is testing if a new way of positioning patients during kidney stone surgery can help them get rid of stones more effectively than the usual position.

What this trial studies
This study evaluates the effectiveness of the T-tilted position during retrograde intrarenal surgery compared to the standard lithotomy position. The aim is to determine if this new positioning can improve the stone-free rate for patients undergoing surgery for kidney stones up to 2.5 cm in size. The research will involve patients aged 16 and older who meet specific eligibility criteria, and it will assess outcomes related to stone removal efficiency. The study is conducted at Ain Shams University hospitals in Cairo.
Who should consider this trial
Good fit: Ideal candidates are patients over 16 years old with kidney stones up to 2.5 cm who do not have a pre-existing ureteral stent.
Not a fit: Patients with previous renal surgery, renal anomalies, active urinary tract infections, or medical conditions preventing the Trendelenburg position may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could lead to higher stone-free rates and improved surgical outcomes for patients with kidney stones.
How similar studies have performed: While variations in surgical positioning have been explored, the specific T-tilted approach is relatively novel and has not been extensively tested in prior studies.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: * 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 Criteria: * 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).
