He had malignant melanoma diagnosed 10\u2009years prior, with recurrent metastases managed through surgery and adjuvant therapy. During his recent admission, metastases to the subcutaneous tissue and retroperitoneum were noted. Contrast\u2010enhanced computed tomography revealed bilateral hydronephrosis and a tumor in the ileal conduit. Endoscopic resection confirmed metastatic malignant melanoma. The patient's renal function stabilized postoperatively, and hematuria was controlled.
