[Disorders of kidney function in patients with benign prostatic hyperplasia]

The examination of 648 males aged 50 to 86 to conduct an early outpatient detection of renal dysfunction in the elderly men employed an original technique of renal function assessment based on the kinetics of urinary 5-NOK elimination. Renal dysfunctions were revealed in 165 patients, in 159 of them the underlying cause was benign prostatic hyperplasia. The results were compared with those obtained at radionuclide tracing and Reberg-Tareev test. The correlation found indicated the authors' technique informative value and its compatibility with the above methods. Identification of renal dysfunction at early stages of benign prostatic hyperplasia allowed their timely hospitalization and operative treatment which enables the physicians to prevent progression of chronic renal failure in these patients.
