Introduction: Some guidelines recommend an early voiding cystourethrography (VCUG) after endoscopic treatment of vesicoureteral reflux (VUR), but there's no consensus if it's necessary a long-term follow-up in these patients. The aim of our study is analyze if it's necessary a delayed VCUG after initial successful treatment with Dx/HA., Material and Method: We have reviewed all medical charts of patients that underwent Dx/HA treatment from 2006 to 2010. We have selected patients with initial successful treatment and more than 3 years of radiological and clinical follow-up. We have analyzed late clinical and radiological outcomes., Results: One hundred and sixty children with 228 refluxing ureters underwent Dx/HA endoscopic treatment with a mean follow-up of 52.13 months. Early VCUG was performed in 215 ureters with an initial successful rate of 84.1%. The group of study was 94/215 ureters with more than 3 years of follow-up with a delayed VCUG. VUR was still resolved in 79,8% of the ureters. Clinical success rate was 91.7%. The incidence of febrile urinary tract infection in those patients with cured VUR and those with a relapsed VUR was 8 and 15%, respectively; but there were no significant differences. We have not found any variable related with relapsed VUR except those ureters that initially received 2 injections (P<.05)., Conclusion: If our objective in the treatment of VUR is to reduce the incidence of febrile urinary tract infection it is not necessary to perform a delayed VCUG even though the long-term radiological outcomes is worse than clinical outcome., (Copyright © 2016 AEU.

Introduction: There is an association between pneumonia and acute glomerulonephritis. Both processes start simultaneously., Patients and Methods: A retrospective study of 6 patients admitted to our centre between 2001 and 2010 with acute glomeruolonephritis associated with pneumonia. The result of the smear and tonsil culture was negative and there was an absence of cutaneous infection., Results: The average age of the patients on admission was 5.9 years with no differences in sex. The diagnosis for pneumonia was made at the time of admission, coinciding with the glomerular symptoms. The most frequent symptoms were fever and macrohaematuria. All had low levels of C3. A significant increase in ASLO was found in 5 cases. The majority of the cases had mild symptoms with the exception of one case of acute renal failure with an initial creatinine of 2.77mg/dL and glomerular filtration rate of 27ml/min/1.73m(2), and two cases with proteinuria in the nephrotic range. All of them progressed satisfactorily without treatment or with minimum diuretic or hypotensive treatment in addition to the appropriate antibiotic treatment with clinical resolution in 7 to 10 days, and C3 returning to normal within a period of less than 4 months., Conclusions: There is an association between acute glomerulonephritis and pneumonia, although it is very uncommon. The ASLOs in our series are not specific for Streptoccocus. pyogenes infection. The respiratory and renal prognosis was favourable in all cases., (Copyright © 2010 Asociación Española de Pediatría.
