Fixed and Reproducible Orthostatic Proteinuria: Results of a 20-Year Follow-up Study

Abstract
A 20-yr follow-up evaluation of young men with fixed and reproducible orthostatic proteinuria showed no evidence of progressive renal disease. Follow-up information was obtained on 43 of the original 64 patients and detailed information was secured on 36. All had normal renal function and only 6 patients continued to show qualitative proteinuria. The prevalence of hypertension found was similar to that of a comparably aged group of the general population. The 20-yr prognosis of patients with fixed and reproducible orthostatic proteinuria is excellent.
