Case Report :
A 72-year-old man was visited emergent department with the chief complaints of dysuria, frequency urination, lower abdominal distension and gross hematuria. Abdominal sonography disclosed one soft tissue lesion over bladder outlet region and right hydroureteronephrosis. Cystourethroscopy with ureteroscopy, which showed one frondlike papillary projection from right ureteric orifice was performed and biopsy was done. The pathologic examination finding was high grade transitional cell carcinoma. Further laparoscopic nephroureterectomy was performed at next admission.
Although a ureteral urothelial cell carcinoma is not rare, this case is interesting for differentiated diagnosis of low urinary tract symptoms by sonography in elderly man at emergent department.
