[Epidemiology of urinary lithiasis in our Unit. Clinical course in time and predictive factors].

Objectives: To analyze the incidence of lithiasis and stone composition in our setting. The trend is compared with the results of the majority of studies on urinary calculi reported in the literature based on the number and composition of stones.

Methods: The study comprised patients referred to the Urolithiasis Unit of our hospital over the last 21 years.

The increased circulating prostate-specific antigen concentrations in women with hirsutism do not respond to acute changes in adrenal or ovarian function.

Serum prostate-specific antigen (PSA) is produced in several female tissues and appears to be up-regulated by androgens. We have studied serum PSA concentrations in women with different forms of hyperandrogenism, focusing on the influence of changes in ovarian and adrenal function on these concentrations. Thirty-seven hirsute women were studied in the follicular phase of the menstrual cycle.
