Minimally invasive treatment for ureteropelvic junction obstruction in adults

Functional Outcome After Laparoscopic and Robot Assisted Management of Uretero-pelvic Junction Obstruction Disease Caused by Crossing Vessels for Adult Patients

Phase 3 Interventional Cairo University · NCT05895422

This study is testing a new, less invasive surgery called vascular hitch to see if it works better than the traditional method for treating adults with ureteropelvic junction obstruction caused by crossing blood vessels.

What this trial studies

This clinical trial investigates the effectiveness of a minimally invasive technique called vascular hitch for treating adult patients with ureteropelvic junction obstruction (UPJO) caused by crossing vessels. Participants will be managed either through the traditional dismembered pyeloplasty or the newer vascular hitch approach. The study aims to compare the outcomes of these two methods, focusing on operative time and hospital stay. By utilizing robotic-assisted or laparoscopic techniques, the trial seeks to demonstrate potential advantages over the classic open surgical method.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old with symptomatic UPJO confirmed by CT angiography due to crossing vessels.

Not a fit: Patients with recurrent UPJO after previous open repair, secondary UPJO after renal surgery, or UPJO in non-functioning kidneys may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to less invasive surgical options for patients with UPJO, resulting in shorter recovery times and improved outcomes.

How similar studies have performed: Previous studies have shown promising results with minimally invasive techniques for UPJO, suggesting that this approach may be effective, though the vascular hitch technique is relatively novel.
