BACKGROUND:

Narrowness of the ureteropelvic junction is the most frequent cause of hydronephrosis in young adults and children. It is characterized by anatomic or functional obstruction of the urine flow from the renal pelvis to the ureter that, when untreated, conditions impaired kidney function.

CLINICAL CASE:

A 22-year-old woman had recurrent urinary infection with poor treatment response for the past 2 years and left lumbar pain of 6-month progression. Computed tomography revealed right renal hypoplasia and left hydronephrosis, for which a left double-J catheter was placed. Robotic-assisted laparoscopic pyeloplasty was performed with no complications or incidents. The patient had adequate progression and was released from the hospital two days later.

CONCLUSIONS:

Robotic-assisted surgery mitigates many of the complications resulting from conventional laparoscopy thanks to its movement precision, suturing ease, and three-dimensional vision. It is also very useful when standard dismembered pyeloplasty may be sub-optimal or technically complicated.
