Gastrointestinal cancers are highly prevalent around the world. In the metastatic setting, the most usual sites for metastases are the liver, lymph nodes, peritoneum, and lung. Urologic metastases are very rare. We report a case series of three patients with gastrointestinal tumours in different topographies (stomach, colon, and rectum) with urological metastases. In all cases, the patients were initially treated with curative intent. Two of the patients presented with bladder metastases, and the third had penile metastases in addition to pulmonary metastases. Haematuria was the most common symptom at presentation. One of the patients had a good overall survival and is still undergoing palliative intent chemotherapy. In the literature, there are few reported cases of urological metastases from gastrointestinal cancers, and that is the aim of this publication.
Keywords: bladder metastasis; clinical case; gastrointestinal cancer; haematuria; penile metastasis.
