[Primary adenocarcinoma of renal pelvis and ureter associated with incomplete ureteral duplication: a case report].
We report a rare case of primary adenocarcinoma of the renal pelvis and ureter in an incomplete duplicated ureter. A 69-year-old male with macroscopic hematuria consulted our hospital. Retrograde pyelography revealed left incomplete duplicated ureter and a filling defect in the lower pole of the ureter. Transurethral ureteroscopy was employed to investigate the filling defect, and a papillary tumor was detected extending into the lower segment of the incomplete duplicated ureter. From these findings, the patient was diagnosed with tumor of renal pelvis and ureter, and left total nephroureterectomy was performed. Pathological diagnosis was adenocarcinoma of the renal pelvis and ureter, INF beta, pT2, pR0, pL0, PV0, PN0. No evidence of either tumor recurrence or metastasis was found on the 3-month postoperative follow up. This case is thought to be the first report of primary adenocarcinoma of the renal pelvis in an incomplete duplicated ureter.
