Urachal Adenocarcinoma Following Kidney Transplantation: The First Case Report

A 53-year-old man who underwent successful kidney transplantation for stage 5 chronic kidney disease presented to our clinic with intermittent painless gross hematuria. Urachal adenocarcinoma, stage III A by Sheldon system, was diagnosed after serial histopathologic and radiological studies. The patient was treated with extended partial cystectomy, en bloc resection of urachus and umbilicus, pelvic lymphadenectomy, and ileocystoplasty. There were no complications seen in this patient. Neither urachal adenocarcinoma recurrence, metastasis, nor de novo uroileal cancer developed during 48-month follow-up. His reconstructed bladder functioned efficiently, without compromising the transplanted kidney function. Our case demonstrated that conservative surgery and augmentation ileocystoplasty could be offered to kidney transplant recipients with localized urachal carcinoma.
