Abstract

Purpose

Most children who suffer renal trauma recover fully; however, some have long-term consequences. We sought to determine what grades of injury carry concern for complication and warrant close follow-up.

Methods

Data on children with grade II or higher renal injuries from a single center over 20 years were reviewed. Demographics, presenting symptoms, lab values, clinical course, management, and follow-up data were analyzed.

Results

One hundred seventy-one children suffered renal injuries: 75% boys, aged 11.6 ± 3.5 years. Falls-54 and sports-43 were leading injury mechanisms. Presentations included pain only-61, pain and hematuria-28 and hematuria alone-11. Eight had pre-existing abnormalities. Injury grades were: grade II-88 (52%), grade III-49 (29%), grade IV-28 (16%), and grade V-6 (3%). No grades II or III patient underwent intervention or suffered sequelae. Grade IV patients underwent: stenting-5, surgery-2, embolization-1, and drainage-1. Grade V patients underwent: surgery-2, embolization-1, and drain-1. Two grade IV patients underwent late interventions: nephrectomy-1 and stenting-1. Six patients, all grades IV–V, were newly hypertensive at follow-up.

Conclusion

Grades II and III renal injuries carry a low risk of complication and repeat imaging and close follow-up are likely not necessary. However, grades IV and V injuries carry a meaningful risk of adverse outcome and close follow-up is warranted.
