Pure large cell neuroendocrine carcinoma of the bladder without urological symptoms

Abstract

Neuroendocrine carcinoma is one of the uncommonly seen pathologies of the urinary bladder. Macroscopic hematuria is frequently encountered
symptom in patients with neuroendocrine carcinoma. We report a 45-year-old man with left solitary kidney and oliguria for five days the
development of acute renal failure (ARF) with the impaired general condition. The underlying cause being identified as pure type large-cell
neuroendocrine carcinoma of the bladder. Large-cell neuroendocrine carcinoma of the bladder is an uncommon fatal tumor. No macroscopic
hematuria or urological symptom was observed in our case. Advanced ectasia was not observed in the kidney, and the patient's clinical status was
complicated with ARF. It must not be forgotten that in some bladder tumors, the patient's general condition may be impaired without urological
symptoms.
