肾移植术后并发自体尿路上皮多器官癌六例的临床分析

Objective To analyze the etiology, clinical diagnosis and outcomes of 6 cases of multifocal urothelial carcinomas following transplantation. Methods A retrospective analysis was performed on 6 cases of multifocal urothelial carcinomas following renal transplantation in our center. Results Six patients were diagnosed as having multifocal urothelial carcinomas, including 1 case of related renal transplantation. Five cases were diagnosed by painless gross hematuria 2～48 months after renal transplantation, and I patient was diagnosed as having bladder tumors by B-uhrasound. All lesions happened un-simultaneously, from 1.5～16 months, and each case accepted operation 2～5 times. One case accepted radical cystectomy and cutaneous ureterostomy of the graft, and one accepted radical cystectomy, cutaneous ureterostomy of the graft and urethrectomy. All of 6 cases received OKT3 or Daclizumab as the induced-immunosuppressive therapy and tacrolimus or cyclosporine A + mycofenolate mofetil + steroid as the maintenance therapy. Intravesical chemotherapy started in all patients immediately after the surgery. All operations were successful and most patients got satisfactory results. Conclusions Kidney recipients have a higher rate of transitional cell carcinomas which are characterized by easy metastasis, and mostly have unsatisfactory prognosis. Kidney recipients with hematuria should be examined carefully with cystoscopy, retrograde pyelography and cystourethroscopy. A routine examination at regular intervals after transplantation is very important.
