Ureteropelvic Junction Obstruction

Ureteropelvic junction obstruction (UPJO) is one of the most common causes of kidney drainage blockages. This condition refers to the obstruction of urine flow from the kidney pelvis to the ureter, which drains urine into the bladder. There are various causes for this blockage, including internal scar tissue, crossing renal vasculature, and kidney stones.
​
Tulane Urology has pioneered robotic pyeloplasty since 2002, becoming one of the early departments in the country to define and refine this procedure. The da Vinci robot is utilized for this surgery. Your urologist will perform appropriate diagnostic imaging and functional studies of the kidney to determine the best management approach for UPJO.
​
During the procedure, the blocked segment of the UPJO is excised, any stones are removed, and adjustments to the renal pelvis are made. The ureter is then reconnected to the kidney pelvis.

Tulane Urology is proud to have initiated this procedure in the region, successfully treating both adults and children. Our peer-reviewed publications have laid the groundwork for this procedure, including adaptations for pediatric patients.​

Additionally, Tulane Urology shares its expertise by teaching the best techniques for pyeloplasty to other robotic surgeons at national and international urology meetings.
