[Ultrasonic diagnosis of ureterocele]

Diagnostic ultrasonic investigation has found many applications in routine urologic practices. The use of ultrasound for the investigation of 19 patients with ureterocele is reported. High diagnostic value, simplicity and noninvasiveness of echographic diagnosis of this congenital malformation of distal ureteral portions and related complications are pointed out. Its advantages over conventional means of ureterocele diagnosis, such as excretory urography and cystoscopy, are demonstrated, while their shortcomings are avoided. Echography is particularly effective in cases of impaired renal activity, doubled upper urinary tract and segmentary ureterohydronephrosis. Ultrasound makes it possible to choose the type of surgical intervention, and exclude angiography from the diagnostic complex in some cases. Follow-up echographic examination after surgery for ureterocele provides adequate information on treatment results.
