Circumcaval ureter with synchronous ipsilateral transitional cell carcinoma of the renal pelvis and the urinary bladder: report of a case and review of the literature
We report a case of concomitant transitional cell carcinoma (TCC) in a circumcaval ureter and invasive bladder cancer. The diagnosis was based on the findings of excretory urography (IVU) and contrast-enhanced computed tomography (CT). IVU showed a typical J-shaped deformity in the dilated right proximal ureteric segment with moderate hydronephrosis and a filling defect in the renal pelvis, while abdominal CT with contrast showed right hydronephrosis with an intrapelvic tumor. The patient underwent radical cystoprostatectomy and nephroureterectomy. No recurrence was detected after 12 months of follow-up.
