Small Cell Lung Cancer Initially Presenting with Acute Urinary Retention: A Case Report

This case study discusses a patient presenting with urinary retention presumed secondary to benign prostatic hyperplasia (BPH). Suspicion for an underlying problem was raised when a second instance of urinary retention occurred after undergoing medical treatment and TUVP to correct BPH. Extensive workup resulted in diagnosis of small cell lung carcinoma with metastases and discovery of a large metastatic mass in the rectovesical pouch. The mass caused obstructive uropathy and renal failure which was managed with stenting and an indwelling catheter. Further investigation by practitioners may be required in patients whose urinary symptoms do not improve after standard BPH treatments.
