Haematuria, Acute Urinary Retention, and Hydronephrosis Due to a Ureteral Polyp: A Case Report and Literature Review.

Ureteral fibroepithelial polyps are quite rare in acute urology emergencies, and their management typically relies on an evidence-based approach. This report describes a unique case involving a 49-year-old woman who presented with flank pain, bleeding, left-sided hydronephrosis, and acute urinary retention. The diagnostic process involved CT scans, catheter insertion, and cystoscopy-leading to the removal of a large foreign body, which was confirmed as an autolysed infarcted ureteral polyp on histology. No recurrence or kidney obstruction was observed at follow-up. We have included a supplementary review of previously published cases and related literature.
