Although algorithms exist for the management of renal trauma in adults
, guidelines have not been established in children. Of 1,175 patients
entered into our Trauma Registry between 1987 and 1991, 61 (5.2%) pres
ented with gross or microscopic hematuria. Eight of the 58 patients (1
3.8%) who had blunt abdominal trauma had major renal injuries. Gross h
ematuria (n = 10) was a significant predictor of major renal injury (n
= 5) (p < 0.001). All 3 patients with microscopic hematuria and a maj
or renal injury also had evidence of multisystem trauma. Admission blo
od pressure, hemoglobin, and trauma score were not predictors of major
renal trauma. All cases were managed nonoperatively except for 1 pati
ent who required a partial nephrectomy for continued hemorrhage. These
data suggest that hematuria of any degree should be evaluated in the
pediatric population, since major injuries can occur with even microsc
opic hematuria or in the absence of shock. Nonoperative management in
this series resulted in no morbidity or delayed complications and sugg
ests that surgical exploration be reserved for ongoing bleeding.
