Urothelial Carcinoma Detected by Ultrasonography in a Renal Transplant Recipient

摘要

Urothelial cell carcinoma in renal transplant recipients has been rarely reported. Here, we report a case of high-grade papillary urothelial carcinoma in a renal transplant recipient who presented with hematuria. Sonographic evaluations (gray-scale ultrasonography, Doppler imaging, and strain sonoelastography) helped with diagnosis in our initial approach to the patient. Computed tomography was performed to confirm solid ureteral masses and staging of the disease. The patient, who underwent nephro-ureterectomy of the graft kidney, had that kidney for 6 years, 6 months. After surgery, the patient was symptom free and without evidence of recurrence or metastasis in 3 years of follow-up. Sonographic examinations have an important role in the evaluation of urothelial carcinoma of transplanted kidneys.
