Abstract Blunt trauma to renal arteries often receives suboptimal management because of delayed diagnosis, incomplete preoperative evaluation, associated injuries, or unknown functional capacity of the contralateral kidney. We propose a rational treatment plan from an analysis of our three cases and a review of 118 cases. Two thirds of the patients were male, and left-sided injuries predominated over right 42.9\% to 30.6\%. In 20 cases the insult was bilateral. Associated injuries occurred in 72\%, averaging 1.6 injuries per case, of which one half were intra-abdominal. Flank and/or abdominal pain was present in 73\% of cases, tenderness in 65\%, and gross or microscopic hematuria in 74\%. Repairs were attempted on 38 renal arteries. "Successful" repairs were accomplished in 16 arteries, while repairs failed in 22. Subsequent hypertension developed in 32\% of successes. Repair should be attempted in stable patients with unilateral injury of less than four hours' duration, bilateral injuries of less than 20 hours' duration, or injuries with nonocclusion on arteriogram.
