Laparoscopic management for fibroepithelial polyp causing ureteropelvic junction obstruction in a child.
An 11-year-old boy with episodes of intermittent gross hematuria and recurrent left flank pain was referred to our institute with left ureteropelvic junction (UPJ) obstruction. (99m)Tc diethylenetriamine pentaacetic acid (DTPA) renography revealed an obstructive pattern in the left kidney, and the existence of a crossing vessel at the UPJ was suspected with excretory urography. Laparoscopic surgery was performed, and intraoperatively no aberrant vessels were found. Upon opening the ureter, a solitary round polyp was found. The segment of the UPJ area containing the polyp was completely removed, followed by laparoscopic dismembered pyeloplasty. Pathologic findings demonstrated a benign fibroepithelial polyp.
