Ureteral duplication and anomalous symptomatology. Presentation of a case

: The authors report a case of unilateral ureteral duplication with extravesical ureteral orifice evaluated with sonography and confirmed by surgery. The peculiarity of the case is founded on the anomalous clinical findings with poorly significant uroculture and the apparent discrepancy between sonographic and urographic finding. The important rule of sonographic evaluation in early diagnosis of kidney malformations is confirmed.
