Background: It is rare for urothelial and renal cell carcinomas to coexist in the same patient, and even rarer for them to be detected simultaneously. Because of this rarity, a standard treatment has not been established and studies about overall survival are scarce. Therefore, physicians must modify treatments according to the individual's situation and the stage of each disease. In recent years, with advances in the instruments and techniques, minimal invasive robotic surgeries have become available for advanced-stage or high-risk patients.
Case summary: An 85-year-old woman with a medical history of hypertension and hyperlipidemia visited our institution. She had visited her local hospital complaining of intermittent, painless, gross hematuria that had started 3 mo earlier. On computed tomography, a right renal mass and left proximal ureteral mass with hydronephrosis were found simultaneously. We decided to perform robot-assisted surgery on both sides during one operation. Considering renal function and kidney loading, right partial nephrectomy was performed first, followed by left nephroureterectomy with bladder cuff excision. At the 6-mo follow-up, no specific symptoms were reported and dialysis was not considered. There were no unusual findings in the imaging study, and regular follow-up and imaging studies are scheduled.
Conclusion: This case report assessed the feasibility of simultaneous minimal invasive robotic surgery as an alternative to conventional open or laparoscopic surgery.
