摘要

We performed a laparoscopic left nephroureterectomy for a patient with primary malignant melanoma of the left ureter. Four months after the surgery, bladder metastasis was observed, and the patient underwent radical cystectomy and cutaneous ureterostomy with pelvic lymph node dissection. One month after the surgery, intra-abdominal lymph node metastasis and pelvic seeding appeared, and the patient received three courses of nivolumab, but the disease progressed. The patient died 10 months after the initial diagnosis.
