Abstract
Aim of the study. Estimation of the decrease of urinary bladder contractility in patients with benign prostate hyperplasia (BPH).
Patients and methods. In 146 BPH patients (mean age 62,1 ± 0,8) urodynamic investigation including uroflowmetry and pressure-flow study was performed. The results of miction cystometry were evaluated using Shafer nomogram, the emptying idex was calculated as relation of voiding volume to maximal cystometric capacity.
Results. 56,2% BPH patients showed the decreased detrusor contractility. The results of urinary bladder contractility estimation by Shafer nomogram are dependent on the degree of infravesical obstruction (IVO). The emptying index is not related to the presence and degree of IVO and characterizes the degree of urinary bladder emptying as well as contraction duration. Concomitant lumbar osteochondrosis and diabetes detoriates urinary bladder emptying. Reliable contractility estimation may only be performed based on urodynamic study since basic BPH patients examination is not sufficient.
Conclusion. In has to be considered during treatment strategy planning that in many BPH patients low urinary truct disfunction is determined by the decrease of urinary bladder contractility and not by IVO.
