Completed Prospective Studies Prospective Evaluation of Blunt Renal Injury in Children

This will be a prospective, definitive data collection of all patients admitted to Children's Mercy Hospital and Phoenix Children's Hospital with blunt renal injury. There will be no study groups as this treatment algorithm is currently in use by surgeons at Children's Mercy Hospital. The medical records of these individuals will be reviewed and data points collected. Data collected include date of injury, age, gender, weight, side of renal injury, grade of injury, mechanism of injury, history of hypertension, last known blood pressure (if possible), radiologic studies, radiologic study results, associated injuries, initial and lowest daily hemoglobin and blood pressure levels for the first 5 days, daily urine output, daily urinalysis for up to 7 days, need for transfusion, type of transfusion, volume of transfusion, number of transfusion episodes, initial and any subsequent urinalysis results, any operations or interventions, length of bed rest (hours), length of hospitalization, length of activity restriction, time to urine cleared of blood, post discharge radiographic studies and findings, follow-up hemoglobin, blood pressure, and urinalysis for all follow-up visits, number of readmissions and reason for readmission, any post injury/post discharge complications and survival. 

Following hospital discharge, all patients will follow up in clinic with one of the investigators with urinalysis checks until the urine is clear and with blood pressure measurements. If the early blood pressures are normal, the patient will be followed every 6 months for 3 years. If hypertension is detected, the patient will be referred to nephrology for treatment and managed as indicated. The period of follow-up will be 3 years. The follow-up after the urine clears is for blood pressure measurements. Therefore, a blood pressure may be obtained by anyone in proximity to the patient as long as the results are sent to the investigators. This will ease the burden for the patients who don't live near the two hospitals.
