ABSTRACT
OBJECTIVE: To evaluate the association between urinary tract infection (UTI), vesical-uretero-renal reflux (VUR) and renal parenchyma damage, without chronic renal failure. PATIENTS AND METHODS: Retrospective study of 85 children with UTI consulting at the ambulatory paediatric unit of a private university centre in Chile, with at least 3 anthropometric evaluations: before, during and after the UTI. The group was divided into two subgroups: with and without VUR. A descriptive and inferential analysis was made. Simple regression modelling and likelihood ratio test was done for the anthropometric measures. RESULTS: Thirty nine children had VUR (46%). Both subgroups were similar. There were no difference in the nutritional status between these. Only girls with VUR have a tendency toward lower height. There was significant association between renal damage, VUR and degree of severity of it. There was no difference in the index weight for height among children with renal damage with or without RVU. In this series, other risk factors as less age, recurrent UTI and bilateral VUR with renal damage, were not cause of malnourish and lower height. CONCLUSIONS: UTI with or without VUR, with or without renal damage, excluding chronic renal failure, might not be a cause of bad physical development in children.

Objetivo. Evaluar la asociación entre infección urinaria (ITU), reflujo vesicoureteral (RVU) y daño del parénquima renal cintigráfico, con alteraciones del crecimiento pondoestatural, en ausencia de insuficiencia renal. Pacientes y métodos. Estudio retrospectivo de 85 niños con ITU que consultaron a la unidad de pediatría ambulatoria de un centro privado universitario chileno, con al menos 3 evaluaciones antropométricas: antes, durante y después de ITU. Se dividieron en 2 grupos: con y sin RVU. Se realizó análisis estadístico descriptivo e inferencias para las variables; así mismo se llevó cabo regresión simple y test de verosimilitud para las curvas antropométricas. Resultados. Treinta y nueve niños (46 por ciento) tenían RVU. Las características de la población fueron similares en ambos grupos, sin presentar alteraciones significativas en el estado nutricional. Sólo las niñas con RVU mostraron tendencia a una menor talla. La presencia de lesión renal se asoció a RVU y a grados severos de éste. No hubo diferencia significativa en el IPT en niños con lesión renal cintigráfica con y sin RVU. Otros factores de riesgo como menor edad, ITU recurrente y presencia de RVU bilateral con daño del parénquima renal cintigráfico, no constituyeron una causa de desnutrición o talla baja en esta serie. Conclusiones. La ITU asociada o no a RVU, con o sin lesión del parénquima renal, en ausencia de insuficiencia renal crónica, no constituiría causa de deterioro del crecimiento pondoestatural en los niños (AU)

The Authors are reviewing their experience of Obstructive Uropathies diagnosed and treated surgically in neonates, the last 8 years in their Institution. 67 cases were reviewed, in which 37 presented with ureteropelvic junction obstruction (UPJ). 13 with posterior urethral valves, 11 with primary megaureter and 6 with ureterocele. Prenatal ultrasonography allowed the diagnosis to be made in two third of the patients. UPJ is the most common obstructive uropathy observed. Posterior urethral valves the most severe because of high pulmonary and renal (dysplasia) complication rate. Surgery, when indicated, has no more complications to be expected than in general population, if oriented prophylactic measures are taken in the early peri- and postoperative period.
