Traumatic renal artery occlusion: 21 cases.

    Summary

    Traumatic renal artery occlusion, often from pedestrian accidents, requires prompt diagnosis. Early recognition and intervention, like arterial reconstruction, can salvage kidney function and prevent hypertension.

    Area of Science:

    • Urology
    • Trauma Surgery
    • Vascular Surgery

    Background:

    • Traumatic renal artery occlusion is a rare but severe injury.
    • It most commonly affects young males following high-impact trauma, such as pedestrian-vehicle accidents.

    Purpose of the Study:

    • To present a series of traumatic renal artery occlusion cases.
    • To highlight diagnostic challenges and management outcomes.

    Main Methods:

    • Retrospective review of 21 cases (16 unilateral, 5 bilateral) of traumatic renal artery occlusion.
    • Analysis of injury mechanisms, diagnostic methods (urography, arteriography), and treatment outcomes.

    Main Results:

    • The primary cause was avulsion or thrombosis following automobile-pedestrian accidents.

  • Key diagnostic signs included absent excretion on urography (unilateral) and anuria (bilateral).
  • Arteriography confirmed the diagnosis; 24% lacked hematuria, and 29% were initially missed at laparotomy. Renal function was salvaged in 2 cases via arterial reconstruction, and 50% developed mild hypertension.

    • Conclusions:

    • Traumatic renal artery occlusion necessitates high clinical suspicion, especially in young males after significant trauma.
    • Timely diagnosis via arteriography and prompt surgical intervention, including arterial reconstruction, are crucial for preserving renal function.
    • Long-term complication of hypertension is common but often manageable.
