Role of the impairment of oxidative metabolism in pathogenesis of lower urinary tract symptoms with benign prostatic hyperplasia and their treatment by alpha1-adrenoblocker alfuzosin.
The role of impairment of general oxidative and energy metabolism in pathogenesis of lower urinary tract symptoms (LUTS) in patients with benign prostatic hyperplasia (BPH) and their correction by (1-adrenoblocker alfuzosin was studied. One group of patients (N = 126) was examined by standard methods for determination of the severity of LUTS by IPSS and mean effective volume of urinary bladder (MEVUB). In the second group (N = 29) in addition to functional examinations, metabolic indicators in blood were measured: antioxidant activity (AOA) and succinate dehydrogenase activity (SDA). Severity of LUTS depends greatly on the MEVUB. It was the first to show a practically complete correlation between LUTS, AOA and SDA. Severity of LUTS exactly correlates with indicators of oxidative and energy metabolism. In patients with more heavy LUTS, lowest AOA and SDA values were found. In the course of effective treatment, both phenomena developed an improvement of clinical symptoms and a rise of biochemical parameters. Close correlation between functional and metabolic phenomena is evidence of an essential role of metabolic mechanisms in the pathogenesis of LUTS with BPH. This opens perspectives to use antioxidants and energy metabolism activators for correction of UB dysfunction in patients with BPH.
