[The urodynamic examination in prostatism].

In a prospective study comprising 29 patients the authors analyzed comprehensively subjective complaints of prostatism using the score of prostatic symptoms (PSS) with the objective urodynamic finding (uroflowmetry, cystometry, pressure flow measurement) in men with benign prostatic hyperplasia. The Boyarsky and Madsen-Iversen PSS did not correlate with the infravesical obstruction assessed by the pressure flow measurements. An obstruction was detected in 23 patients (79.3%), incl. a marginal one in 6 patients (20.7%), the diagnostic sensitivity of free uroflowmetry being 90.9%. Cystometry did not reveal a significant difference between the group with and without an obstruction, instability of the detrusor was found in 12 patients (41.4%) with a significant difference of the maximal cystometric capacity, as compared with the group of patients with a stable detrusor.
