Comparación entre el ancho del parénquima renal y la función renal en niños con valvas de uretra posterior en el Hospital Roberto Gilbert Elizalde en los años 2015 – 2016

Abstract

ABSTRACT: Posterior urethral valves (PUV) are a cause of morbidity and mortality being the most common cause of chronic kidney disease, there are some options for the assessment of these boys which include nadir creatinine and seeing changes in the renal parenchyma, the aim of these study is to determine if the thickness of the renal parenchyma in the renal ultrasound is associated with changes in the renal function in boys with posterior urethral valves. MATERIALS AND METHODS: Our study population where 13 boys with diagnosis of posterior urethral valves in the period between January 2015 to December 2016 in theoutpatient urology consult of pediatric hospital Roberto Gilbert Elizalde that met the inclusion and exclusion criteria of our study. We compared the thickness of the renal parenchyma with the kidney function. RESULTS: of the 13 patients with posterior urethral valves we correlate the renal parenchymal thickness with kidney function, in total we had 26 kidneys kidneys (13 right and 13 left). Of the 13 right kidneys, 3 kidneys had a parenchymal thickness below the 3th percentile with an altered kidney function which corresponds to 23,07% of the population, 5 kidneys had renal parenchyma thickness below the 3th percentile with normal kidney function (38,46%) and 5 kidneys had normal renal parenchymal thickness with normal kidney function (38,46%) witha p=0,11 value not statistically significant. Of the 13 left kidneys, 1 kidney had a renal parenchymal thickness below the 3th percentile with an altered renal function which corresponds to 7,69% of the population, 6 kidneys had a renal parenchymal thickness below the 3th percentile with a normal kidney function (46,15%), 2 kidneys had normal renal parenchymal thickness but with an altered kidney function (15,38%) and 4 kidneys with normal renal parenchymal thickness and normal renal function (30,76%) with ap=0,41 value not statistically significant. VIII CONCLUSIONS: We couldn´t demonstrate the relationship between reduced renal parenchyma thickness and changes in the renal function in boyswith posterior urethral valves.
