A rare cause of ureteric stricture and hydronephrosis: metastatic esophageal cancer to the urinary bladder

Abstract

The presence of hydronephrosis usually signifies the presence of significant urinary tract obstruction, more commonly at the level of the ureter, and occasionally at the bladder outlet in cases of bilateral hydronephrosis. Unilateral hydronephrosis is most commonly caused by a ureteric stone or stricture, and rarely caused by neoplasm. Metastatic disease to the urinary bladder is rare and usually presents with hematuria, and we report the first case of hydronephrosis resulting from a metastatic esophageal cancer to the bladder.

Metastatic esophageal cancer presenting as bladder mass, a case report

“…Patients presented with episodes of gross hematuria anywhere from 9 months to 2 years after initial treatment of their primary esophageal tumor with curative resection or chemotherapy with Cisplatin, 5-Fluorouracil, and Herceptin. 4 , 5 In 2019, Goh et al described a patient presenting with new onset left hydronephrosis nine months after treatment of his poorly differentiated esophageal carcinoma. 5 Cystoscopy demonstrated tumor at the left ureteric orifice and final pathology was consistent with metastatic disease.…”
