[Diagnostic scale of infravesical obstruction in patients d with benign prostatic hyperplasia].

A clinical diagnostic scale of infravesical obstruction (IVO) in patients with benign prostatic hyperplasia is proposed which provides the diagnosis of IVO in BPH patients with probability up to 89% basing only on clinical evidence obtained at a detailed urological examination (size of the gland, size and index of the prostatic transitional zone, residual urine, micturition urine, maximal micturition rate).
