RESUMO
Authors describe a case of newborn whose malformations of genitourinary tract of abdominal muscles deficiency and renal dysplasia make it very compatible with Prune-Belly Syndrome. The case it is exceptionally interesting because it is a female subject; and on the other hand because of its' associated malformations. The so debated pathogenic of the Syndrome is commented.

This report describes the first pediatric case of chronic renal failure as a complication of infectious mononucleosis in a 3 1/2 year old girl. The clinical features were marked at onset by proteinuria and later by nephrotic syndrome. The evolution to chronic renal failure took about two years. In the renal biopsy, lesions characteristic of interstitial nephritis were observed, associated with focal and segmental glomeruloesclerosis and deposits of C3 in granular and discontinued form. Renal participation in infectious mononucleosis is not unusual and fundamentally it is manifested by proteinuria and abnormalities of urinary sediment, with interstitial nephritis as a characteristic lesion in the renal biopsy.

Classically it is considered that vital prognosis of Lesch-Nyhan syndrome depends on renal affectation secondary to uric nephropathy. A case of Lesch-Nyhan syndrome treated with Allopurinol is described which presented multiple and bilateral renal stones by precipitation of xanthine. Treatment with Allopurinol inhibits the formation of uric acid and qualitatively renal excretion of oxypurines modifies. In special circumstances (disminution of urinary output and pH), they can precipitate and originate a radiotransparent lithiasis with uric lithiasis. Interest of this case, lies in being alert to possible xanthine stone formation in patients with a large excretion of purinics metabolites, who are treated with Allopurinol.
