Renal ionoregulation function in incontinent women

Abstract

Renal ionoregulation function was studied in 143 women with stress incontinence, in 43 with urge incontinence and in 91 with mixed incontinence. Total polyuria was diagnosed in 8,7 ± 1,7% and nocturnal polyuria in 21,7 ± 2,5% incontinent wonen. Changes in kidney function in total and nocturnal polyuria appear to be due not to a decrease in water reabsorption in the renal collecting duct but to reduction of ion reabsorption in the thick ascending limb of the Henle loop. Due to this defect, reabsorption of ions and water is decreased; as a result, lager volumes of fluid enter the collecting ducts.
