Study used a silk thread to create an animal model of “bladder outlet obstruction (BOO),” which is a condition affecting nearly 30% of men over the age of 60 and usually caused by benign prostatic hyperplasia (BPH).

FTA:

The bladder pressure was significantly increased in obstructed rats relative to sham rats. However, the peak voiding pressure of bladders in obstructed rats treated by SFN is lower than obstructed rats at the 4-week time point. Bladder capacity was significantly higher in BOO rats compared to sham rats. Rats of the BOO+SFN group showed the highest bladder capacity among all groups. Bladder compliance decreased significantly at the 4-week time point after BOO. However, SFN treatment rescued the compliance increase in bladder capacity. Moreover, we found that the interval of micturition was shorter in BOO rats than in sham rats. The micturition interval in BOO+SFN rats was significantly increased compared to BOO rats (Table 2).
