title: Gigantic ureteral diverticulum or pelvic cyst?
abstract: Ureteral diverticulum is a rare anomaly, and very few reported cases concerning it can be found in literature. We report a 3.5-year-old boy who presented with urinary tract infection, rare voiding, and straining during voiding. Ultrasonography and magnetic resonance imaging showed a cystic pelvic mass. At surgical intervention, however, a massive ureteral cystic structure communicating both with the ureteropelvic and ureterovesical portion of the ureter was observed. Finding the presence of a smooth muscle layer, the pathologist confirmed this to be a true diverticulum. The fact that fenoterol (which was used for the prevention of preterm labor in the boy's mother) significantly decreases frequency and amplitude of upper urinary tract contractions suggests that fenoterol treatment might have influenced the occurrence of this abnormality.
