URETERAL OBSTRUCTION BY UROLITH IN CATS: CASE REPORT

Abstract

Ureteral obstruction caused by uroliths is an emerging condition in feline clinical practice, characterized by partial or complete blockage of urinary flow between the kidneys and the bladder. Often silent in its early stages, this disorder can progress rapidly to serious complications such as hydronephrosis, pyelonephritis, and acute kidney injury, especially when diagnosis is delayed. This study aimed to analyze the main predisposing factors, pathophysiological aspects, clinical complications, and diagnostic and management strategies related to ureteral obstruction in felines, through a literature review supported by a real clinical case. The case analysis highlighted the importance of continuous monitoring and early detection of laboratory and ultrasonographic changes as essential tools to prevent irreversible renal damage. Findings confirm that inadequate diet, genetic predisposition, metabolic disorders, and low water intake are key contributors to ureteral stone formation. It is concluded that effective management of ureteral obstruction requires an individualized approach, integration of diagnostic and therapeutic techniques, and strong preventive action focused on caregiver education and improving the quality of life of affected cats.
