Treatment in Pediatric Renal Trauma: A Conservative Management Approach

PURPOSE: The management of pediatric trauma is substantially derived from the results of adult trauma patient. Despite the increasing of pediatric renal trauma, the management of them still remains controversial. The aim of this study is to evaluate our experience with the expectant conservative management of blunt trauma in children. MATERIALS AND METHODS: We retrospectively studied 45 pediatric patients with renal trauma between 1995 and 2007. We reviewed medical records for clinical symptoms, mechanism of injury, assigned grade of renal injury, associated injuries, indication of surgery, and treatment outcomes. We graded renal injuries according to the American Association for the Surgery of Trauma Organ Injury Scale. RESULTS: All patients of grade I, II, III, and IV were managed conservatively at beginning, if the hemodynamic state is stable. Among them, 2 patients of grade IV were done delayed operation. One patient underwent delayed renorrhaphy for persistent anemia and hypotension, and the other patient needed delayed nephrectomy because of persistent fever and worsening abdominal pain with significant urinary extravasation. All patients of grade V were undergone early nephrectomy. CONCLUSIONS: Except for persistent fever with significant extravasation and grade V injury, initial conservative management of blunt renal trauma in children is effective and recommendable at beginning, if the hemodynamic state is stable. Prospective larger randomized controlled trials will be needed.

Renal Angiomyolipoma Partially Containing Epithelioid Component / 대한비뇨기과학회지

Epithelioid renal angiomyolipoma is a recently recognized pathologic variant of angiomyolipoma, which represents a more malignant course than a classical renal angiomyolipoma. We report a case of histologically proven renal angiomyolipoma. The patient presented with the symptoms and signs of spontaneous rupture of the kidney. On surgical exploration, the ruptured kidney with upper pole kidney mass was resected. The enlarged regional lymph nodes were also removed, which showed the same pathology.
