RESUMEN

We compared the efficacy of a routine sulphosalycilic acid method and a new technique of pirogallolic red staining for urine protein assay in children with metabolic nephropathy, crystal-calcium crystaluria. The former method was found ineffective in proteinuria diagnosis in children with metabolic nephropathy. The pirogallolic method appeared more effective as it detects microproteinuria and therefore allows accurate diagnosis, control of its treatment and finally to improve the results of therapeutic and prophylactic measures.
