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

Abstract

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.

Complete Transperitoneal Laparoscopic Nephroureterectomy in Circumcaval Ureter with Upper Tract TCC: Initial Case Report

“…2 The plausible hypothesis ascribed to tumorigenesis in such a condition is the urine stasis occurring in a dilated collecting system of a CCU. 3 With the advent of minimally invasive surgery (MIS), there are unique challenges that present to the operating surgeon; the foremost among them being the questionable wisdom of doing a traditional nephroureterectomy. It is not possible to remove the intact specimen without dismembering, since the large bulk of kidney is practically impossible to transpose.…”
