Purpose:
The aim of the study is to examine the follow-up and treatment results of late renal functions in children with high-grade (Grades 4, 5) renal trauma resulting from blunt abdominal injury.
Methods:
The follow-up and treatment reports of 41 patients with renal trauma admitted to our clinic between the years 2005 and 2015 were reviewed retrospectively.
Results:
Eight of the 41 cases had Grade 1, five had Grade 2, and 12 had Grade 3 renal trauma. The remaining 16 cases (12 of which were Grade 4, four were Grade 5) had high grade renal trauma. Four (25%) patients with high-grade renal trauma were operated (JJ stent placement was performed on one, renorraphy was performed on two, pyeloplasty and urinoma drainage were performed on one), and 12 patients were followed conservatively. In the long-term follow-up (>1 year), Tc-99m mercaptoacetyltriglycine (MAG3) kidney scintigraphy examination of three (30%) patients out of the 10 patients who were followed up conservatively, the affected kidneys were found to be nonfunctional (renal differential function 0%). The mean differential renal function in four patients who underwent surgery was 31% (between 25% and 40%).
Conclusion:
It should be kept in mind that kidneys may become atrophic or non-functional in the late period of follow-up in cases that are followed conservatively due to high-grade renal trauma. There is no standard algorithm or treatment method in the management of high-grade renal trauma. In order to achieve a good outcome, the treatment should be individualized as much as possible.
