title: [Rhythm of diurnal and seasonal urine excretion in calcium oxalate-urinary calculi patients and healthy humans and its effect on the incidence of calculi].
abstract: Distinct sinus-like variations in the production of urine - with regard to diurnal as well as seasonal rhythms - result in an increased risk of stone formation in the months of May, June, September and November (concerning seasonal rhythm) and between midnight and 6 a.m. (concerning diurnal rhythm). Other data of importance influencing urinary excretion are sex, age and supply of fluid.
