Introduction: The non operative management (NOM) is the standard management of splenic and liver blunt trauma in pediatric patients.Hemodynamic instability and massive transfusions have been identified as management failures. Few studies evaluate whether there exist factors allowing anticipation of these events. The objective was to identify factors associated with the failure of NOM in splenic and liver injuries for blunt abdominal trauma., Patients and Method: Retrospective analysis between 2007-2015 of patients admitted to the pediatric surgery at University Hospital Saint Vincent Foundation with liver trauma and/or closed Spleen., Results: 70 patients were admitted with blunt abdominal trauma, 3 were excluded for immediate surgery (2 hemodynamic instability, 1 peritoneal irritation). Of 67 patients who received NOM, 58 were successful and 9 showed failure (8 hemodynamic instability, 1 hollow viscera injury). We found 3 factors associated with failure NOM: blood pressure (BP) < 90 mmHg at admission (p = 0.0126; RR = 5.19), drop in hemoglobin (Hb) > 2 g/dl in the first 24 hours (p = 0.0009; RR = 15.3), and transfusion of 3 or more units of red blood cells (RBC) (0.00001; RR = 17.1). Mechanism and severity of trauma and Pediatric Trauma Index were not associated with failure NOM., Conclusions: Children with blunted hepatic or splenic trauma respond to NOM. Factors such as BP < 90 mmHg at admission, an Hb fall > 2 g/dl in the first 24 hours and transfusion of 3 or more units of RBC were associated with the failure in NOM.

Objective: In order to evaluate the efficacy of different surgical techniques for the correction of traumatic lesions of the urethra, we performed a retrospective study in those patients, and evaluated different complications such as postsurgical stenosis of the urethra, incontinence and impotence (erectile dysfunction)., Methods: A retrospective study was conducted, reviewing the clinical charts of 43 patients admitted to the San Vicente of Paul Hospital, with diagnosis of traumatic rupture of the posterior urethra from 1987 to 2007. We analyzed different demographic data, type of surgical correction, early and late complications., Results: The average age of the patients was 7.7 years, the average follow up was 30.6 months, and all the patients were male with a posterior urethral rupture. 27 Patients underwent a primary urethral repair (63%), 13 patients underwent a cistostomy with later urologic reconstruction (30%), in 3 patients (7%) other surgical procedures were made. Overall complication rate was 39.5%. These complications were: Urethral stenosis, 26 patients (60.5%), urinary retention secondary to obstruction, 10 patients (23.3%), incontinence 10 patients (23.3%) and impotence 7 patients (16.3%). Patients treated with a primary urethral repair presented a significantly less development of infection, obstruction and stenosis, (p<0.05). Patients with pelvis fracture associated to urethral trauma had a significant higher risk of developing stenosis and impotence. (p<0.05)., Conclusions: Both different surgical techniques compared showed a similar complication and morbidity rates in middle follow up. Each procedure should be selected according to clinical condition of the patient, the extension of the urethral damage, the associated traumatic lesions and the surgeon's expertise. In our searched patients, treated with a primary urethral repair we found a significantly less development of infection, obstruction and stenosis.
