[Lesions of the renal pedicle in blunt abdominal trauma in children. 7 cases].

The frequency of urinary tract trauma in children is difficult to estimate. Renal pedicle lesions are estimated to represent 10% of all forms of urinary tract trauma. These lesions are difficult to diagnose and may be completely missed. Over a 12 year period, we have treated 7 children with a renal pedicle injury. Haematuria was immediate in 3 cases, delayed in 2 cases and absent in 2 cases. The diagnosis is based on intravenous urography or postcontrast computed tomography. Treatment consisted of disobstruction with intimal suture with a good result, but impaired renal function, an upper pole nephrectomy, functional aorto-renal bypass graft but with altered renal function, total nephrectomy and 3 cases of surveillance with one non-functioning kidney. None of these children are hypertensive. The authors discuss the diagnostic approach, the contribution of imaging and the therapeutic options and results.
