Bladder Preservation After Bilateral Kidney Loss and Bladder Cancer After Renal Transplantation: A Case Report.

Abstract

Kidney transplantation is now a well-established renal replacement therapy. However, renal transplant recipients are reported to have an increased incidence of cancer. Although the recommended waiting period after each cancerous event in a recipient is indicated in the literature, there is no absolute certainty that cancer will develop even after the recommended waiting period. In this study, we experienced a case of bladder cancer after the recommended waiting period in a patient who had bladder preservation after a right nephrectomy and left nephroureterectomy. A 61-year-old man lost his right kidney due to renal cancer in 2007 and his left kidney to urothelial carcinoma in November 2017. The patient wanted a kidney transplant and bladder preservation at the time of the left nephroureterectomy. The patient's wife offered to donate a kidney. After 2 years of hemodialysis, there was no recurrence or metastasis, and with the approval of the Ethics Committee, the patient received a kidney transplant in January 2020. Although the patient's renal function was good after the transplant, a bladder tumor was found 20 months later and was resected transurethrally. The pathology was nonmuscle invasive bladder cancer. This patient, who had lost both kidneys, was treated with bladder preservation therapy. After subsequent kidney transplantation, he developed bladder cancer. Explaining to the patient the possibility of recurrence after a certain period and the increased risk of cancer, in-depth consultation with the patient is necessary regarding bladder preservation. Regular checkups should be continued after transplantation.
