ABSTRACT
AIM:
To specify the pathogenetic link between blood supply of the bladder neck and lower urinary tract symptoms (LUTS). MATERIAL ANDMETHODS:
The study involved 78 men aged 26 to 50 years, including 19 patients with multiple sclerosis (MS) and LUTS, 29 patients with chronic prostatitis category IIIB with LUTS and 30 patients with chronic prostatitis category IIIB without LUTS (control group). All the patients underwent Doppler ultrasonography of prostatic arteries and selective study of blood flow in the neck of the bladder. Pharmacological test using combinations of 1-blockers (1-AB) with m-anticholinergics (m-CB) and phosphodiesterase type 5 inhibitors (PDEI-5).RESULTS:
The changes in the blood circulation of VUS were found to correlate with LUTS. The response of blood flow depended not only on the type of pharmacological agents, but also on the degree of vascular changes and neurological deficit in VUS.DISCUSSION:
The findings of VUS vascular pharmacological tests with PDEI-5 and 1-AB + m-CB were comparable in chronic prostatitis with non-neurogenic LUTS and in MS with neurogenic LUTS. Vascular reaction in VUS depends on the presence of neurological deficit. The combination of (1-AB+ m-CB) increases the blood circulation of the bladder neck and prostate and reduces the LUTS. PDEI-5 reduces LUTS due to the positive effect on the blood circulation of the prostate and VUS.CONCLUSION:
Circulatory abnormalities (=hypoxia) in VUS is an important pathogenetic mechanism of neurogenic and non-neurogenic LUTS and the way to compensate them using a combination of (1-AB+ m-CB) or PDEI-5. Therefore, one of the mechanisms of LUTS is associated with impaired blood flow in the bladder neck and VUS.Key words
