The aim of this study was to investigate whether supplementation of estrogen in the female rabbit with partial bladder outlet obstruction (PBOO) would affect the severity of bladder dysfunction.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We surgically created PBOO in female New Zealand White rabbits. Group 1 included sham operated rabbits which served as controls. Group 2 received PBOO without estrogen treatment. Group 3 received estrogen treatment after PBOO. Group 4 received estrogen pretreatment before PBOO. The bladders were then removed for contractile, biochemical, and protein expression studies. There were four rabbits per group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>(1) PBOO resulted in significant decreases in the contractile responses to all forms of stimulation (field stimulation [FS], carbachol, KCl, ATP). Both pretreatment and post\u2010treatment with estrogen resulted in significantly increased contractile responses to all forms of stimulation, although the responses were still lower than control. (2) PBOO resulted in a significant decrease in the activity of choline acetyltransferase (ChAT). Both pretreatment and post\u2010treatment with estrogen resulted in significant increases in ChAT activity back toward control levels. (3) PBOO resulted in significant increases in both protein oxidation and nitration; both pretreatment and post\u2010treatment with estrogen significantly reduced oxidation and nitration toward control levels.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Estrogen pretreatment and post\u2010treatment in the female rabbit ameliorated contractile and biochemical dysfunctions associated with PBOO. This improvement is likely due to reduced oxidative stress. As expected, pretreatment was generally more effective than post\u2010treatment. Neurourol.
