[7-year-follow up (1987-1994) of a population with asymptomatic persistent microhematuria and normal renal function].
A group od 129 patients with persistent asymptomatic microhematuria was studied for 7 years (1987-1994). At the beginning of the study, 31 patients showed mild proteinuria (less than 1 g/day) and in the rest of 98 patients, 21 showed microalbuminuria. At the end of the study none of the patients developed renal failure, urological disease, hypertension. Six patients out of 31 with mild proteinuria (less than 1 g/day), developed an increase of proteinuria over 2 and 3/day and underwent a renal biopsy while 2 out of 21 patients with altered microalbuminuria completely recovered after the follow-up period. The rest of 77 patients at the end of the study still showed isolated microhematuria. The results of this study support the hypothesis that in a population with age range between 16 and 28 years, the presence of persistent microhematuria, also associated with mild proteinuria, even for a long time, does not seem to lead to changes of renal function or to urological diseases.
