Simultaneous robot-assisted approach in a super-elderly patient with urothelial carcinoma and synchronous contralateral renal cell carcinoma: A case report

Chromophobe renal cell carcinoma with ipsilateral ureteral urothelial carcinoma: A case report

It is very rare for different types of urological tumours to occur together, and it is even rarer for chromophobe renal cell carcinoma (CRCC) to be combined with ipsilateral ureteral urothelial carcinoma (UUC), and the symptoms are relatively homogeneous, mostly presenting as symptoms that can be observed in malignant tumours alone, and therefore are often easily missed. In the present study, a case of a patient who was admitted to the hospital for more than 3 months with no obvious cause of terminal carnivorous hematuria was reported, and ureteral carcinoma was considered in the preoperative diagnosis but not renal carcinoma. After completion of preoperative tests, laparoscopic right nephrectomy and right ureterectomy was performed. The postoperative pathological diagnosis was CRCC of the right side and low-grade UUC of the right side, and the patient did not show any significant abnormality at the postoperative follow-up. By discussing this case and reviewing the relevant literature, the present study provides clinicians with more insight.
