Abstract
Purpose: We examined the effect of stress on the pathophysiology of bladder stability in terms of enzyme levels, Rho-kinase, and bladder relaxation.
Materials and Methods : A total of 48 female Sprague-Dawley rats were studied in scheduled stress environments for 7, 14, and 28 days; 24 rats were in the control group and 24 rats were in the test (stressed) group.
Results: Estrogen decreased significantly whereas testosterone and dopamine increased significantly in the stress group (p£¼0.05). Rho-kinase was significantly increased in the rats exposed to stress stimuli for 14 days (p£¼0.05). Collagen types I and III in the bladder tissue were significantly higher in rats exposed to stress for 14 days and 28 days (collagen type I in the 14-day group, p£¼0.01; collagen type I in the 28-day group, p£¼0.05; collagen type III in the 14-day and 28-day groups, p£¼0.05). Voiding frequency increased significantly as the duration of stress exposure was prolonged, in addition to a significant decrease in volume per voiding (p£¼0.05).
Conclusions: The changes observed in micturition pattern, factors that contribute to smooth muscle contraction, and relaxation in the female rat bladder support the hypothesis that stress affects bladder stability.
