How to diagnose and differentiate soft spot of urinary tract?

It is mainly based on finding typical urothelial soft spot cells in urine or living tissues to differentiate urothelial soft spot from urinary tract infection and tumor. There is no specificity in imaging findings of renal plaques. It is difficult to differentiate from renal malignant tumor, and the enlarged renal contour can be shown in abdominal X-ray,

Intravenous urography showed that the renal pelvis and calyces were compressed. According to the development of the disease, the renal excretion function could be weakened or even had no function, and the affected kidney did not develop. B-mode ultrasonography showed enlarged kidney, unclear boundary of cortex and medulla, multifocal hyperechoic area and occasionally diffuse hypoechoic area in renal area, which was difficult to differentiate from abscess.

CT scan of the kidney usually showed inhomogeneous mass with necrosis. Enhanced CT scan showed low density area in the lesion. Renal angiography showed that the branches of the internal renal artery were compressed and abducted, and sometimes new blood vessels could be seen. Urography showed filling defect. Cystoscopy showed bladder tumor and inflammatory changes.
