[Giant orthotopic ureterocele. Diagnosis by ureteral jet detection with doppler color ultrasonography]. / Ureterocele gigante ortotópico. Diagnóstico por detección del jet ureteral mediante ecografía doppler color.

OBJECTIVE: To present an additional case of orthotopic ureterocele in a patient that consulted for hematuria and outlet obstruction, with special reference to the utility of non-invasive color doppler ultrasound in the diagnosis of this condition. METHODS/RESULTS: This condition was suspected on detecting a ureteral jet inside a cystic lesion of the bladder. The diagnosis was confirmed by IVP and cytoscopy. Treatment was by transurethral resection with good functional results. CONCLUSION: Color doppler ultrasound is useful for the diagnosis of ureteroceles, particularly in patients in whom contrast or ionizing radiation must be avoided.
