Anuria Secondary to Bilateral Obstructing Ureteral Stones in the Absence of Renal Colic

BACKGROUND Obstructing ureteral stones are a rare cause of anuria, which is typically from prerenal or renal etiologies. Classically, obstructive stones cause moderate to severe renal colic. Urolithiasis is rarely considered during evaluation of painless anuria. CASE PRESENTATION We present an unusual case of a 73-year-old Caucasian female who presented with anuria and was found to have large bilateral obstructing ureteral stones in the absence of renal colic. CONCLUSION Given that patients with obstructive anuria can be asymptomatic, urolithiasis should be considered in all patients presenting with anuria.
