Renal cell carcinoma metastasis in the bladder diagnosed based on transurethral resection after hematuria: a case report

Abstract

Introduction: Despite the population's greater access to imaging tests and consequent diagnosis of renal cancer in early stages, we continue to encounter neoplasms in locally advanced and metastatic stages. Case report: We report a patient admitted to the emergency department of the Hospital Geral de Fortaleza with hematuria and urinary retention. After the patient underwent computed tomography and transurethral resection, a diagnosis of renal cell carcinoma metastasis in the bladder was confirmed based on immune histo chemistry results. Discussion: Metastasis of renal cell carcinoma in the bladder is rare, with few cases reported in the literature on synchronic presentation. Final considerations: Although rare, we must consider the possibility of metastasis of renal cell carcinoma in patients who present with hematuria, especially in those previously diagnosed with renal cancer.
