title: Conservative management with percutaneous intervention of major blunt renal injuries.
abstract: This retrospective study assessed the results of treatment of patients with renal trauma to determine the optimal management (conservative or surgical) for patients with grade III renal injuries. During the past 12 years 108 patients (including 43 children) with renal injuries were managed: 43 had grade I injuries (renal contusion), 33 had grade II (minor laceration), 31 had grade III (major laceration), and 1 had grade IV (pedicle injury). All patients with grades I and II injuries were successfully managed conservatively. The patient with renal pedicle injury underwent uneventful nephrectomy. Nineteen patients with grade III injuries (including 5 patients with shattered kidneys and 3 patients with polar avulsion) were managed conservatively, and 2 developed progressively enlarging urinomas that required percutaneous drainage with complete resolution. No patient in this group developed perinephric abscess or urinary fistulae, and no delayed nephrectomy was necessary. Long-term follow-up of 7 patients in this group, including 3 with shattered kidneys and 2 with polar avulsion, showed that none have developed hypertension. Twelve patients with grade III injuries were managed surgically. Six (50%) patients underwent total (4 patients) or partial (2 patients) nephrectomy. In 6 patients, the surgical intervention was only open drainage of the perinephric collection and/or parenchymal suturing. It was concluded that conservative management with timely percutaneous or endoscopic intervention in patients with major renal injuries results in minimal loss of renal tissue without significant late complications.
