The effect of different methods of storage on the results of serum total CO2 assays.

Metabolic acidosis frequently complicates end-stage renal failure. In haemodialysis patients its severity is usually monitored by measurement of the total CO(2) (TCO(2)) level. Samples from 'satellite dialysis' patients are often stored prior to analysis.

A prospective study of the natural history of hematuria associated with benign prostatic hyperplasia and the effect of finasteride.

Purpose: We prospectively studied the effect of finasteride on chronic hematuria associated with benign prostatic hyperplasia.

Materials And Methods: We prospectively evaluated 57 patients with chronic intermittent hematuria who were randomized to a finasteride treated or a control arm.

Results: In the untreated control group hematuria recurred in 17 patients (63%) within a year but in only 4 (14%) in the finasteride group, which was a statistically significant difference (p <0.
