Management of Grade V Devascularized Kidney

Initial Assessment and Management

The primary determinant of initial management approach for patients with devascularized kidney is hemodynamic status, with hemodynamically unstable patients requiring immediate intervention, according to the World Journal of Emergency Surgery 1, 2
Hemodynamically stable patients with devascularized kidney can be managed non-operatively, as recommended by the World Journal of Emergency Surgery 1, 2
Diagnostic imaging with IV contrast-enhanced CT with immediate and delayed images should be performed when renal injury is suspected to accurately grade the injury and identify associated injuries, as suggested by The Journal of Urology 3

Immediate surgical intervention is indicated for hemodynamically unstable patients with uncontrollable life-threatening hemorrhage, avulsion of the renal pedicle with pulsating/expanding retroperitoneal hematoma, or renal vein lesion without self-limiting hemorrhage, according to the World Journal of Emergency Surgery 1
Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) may be used as a bridge to definitive hemorrhage control in severely unstable patients, as recommended by the World Journal of Emergency Surgery 1
Non-operative management is the standard of care for hemodynamically stable patients, with follow-up CT imaging performed to monitor for complications, as suggested by The Journal of Urology 3

Angiography with super-selective angioembolization is indicated for arterial contrast extravasation, pseudoaneurysms or arteriovenous fistulas, and non-self-limiting gross hematuria, according to the World Journal of Emergency Surgery 5
For main renal artery injury in specialized centers, angioembolization or percutaneous revascularization with stent/stentgraft may be considered if warm ischemia time is <240 minutes, as recommended by the World Journal of Emergency Surgery 5
Success rates for arterial repair are only 25-35%, making this a challenging intervention, as noted by the World Journal of Emergency Surgery 1

Initial observation is appropriate for stable patients with urinary extravasation, with urinary drainage performed if complications develop, as suggested by The Journal of Urology 6
Drainage options include ureteral stent, possibly augmented by percutaneous urinoma drain or percutaneous nephrostomy, according to The Journal of Urology 6

Monitor for development of renovascular hypertension, with periodic blood pressure monitoring for up to a year recommended, as suggested by The Journal of Urology 6
In rare instances with uncontrollable hypertension and a functional contralateral kidney, delayed nephrectomy may be necessary, according to the World Journal of Emergency Surgery 1

Rushing to surgery for a devascularized kidney in a hemodynamically stable patient without other indications for laparotomy, as cautioned by the World Journal of Emergency Surgery 1, 2
Attempting arterial repair in a severely damaged kidney with prolonged warm ischemia time (>240 minutes), as warned by the World Journal of Emergency Surgery 5
Failing to perform follow-up imaging for grade V injuries, which have high complication rates, as emphasized by The Journal of Urology 3
Not monitoring for renovascular hypertension, which can develop as a late complication, as advised by The Journal of Urology 6
