The Diagnosis And Treatment Of AAST â…¢-â…¤ Grade Renal Trauma (with 33 Cases Report)

Renal injuries occur in approximately 5%-10% of all abdominal trauma, and 1%-5% of all trauma, but only 2% require surgical intervention. With the development of imageology and the accumulative experience of conservative management, more and more patients with renal injuries needs no surgical interventions.But there are still some patients have to be treated by surgery. We retrospectively analysed 33 Cases of AAST III-V Grade renal trauma, and summarize the experience on the diagnosis and treatment of renal trauma.Objective: To present an experience with 33 Cases of AAST III-V Grade renal trauma.Methods: 33 cases of AAST III- V Grade renal trauma were retrospectively analysed, including 7 cases of AAST III Grade renal trauma, 19 cases of AAST IV Grade renal trauma, and 7 cases of AAST V Grade renal trauma.Results: Emergent surgical managemeat was carried out in 4 patients, the others were proposed to be treated nonoperatively. 23 cases were successfully treated by nonoperative way, 10 needed operative intervention. 26 patients were well followed up. 17 patients with AAST III-IV Grade and 1 patient with AAST V Grade renal trauma had good renal function.Conclusion: Conservative management of AAST III-V Grade renal trauma is appropriate in hemodynamically stable patients. Percutaneous catheter or ureteric stenting drainage, selective renal artery embolization, and surgical interventions are needed if necessary.
