Except the SHAM group, all animals in remaining four groups underwent surgery for PUO. No further treatment was given to the first group (NT group). Remaining three groups received 6 weeks of treatment with 20\u2009mg\/kg doxazosin (D group), 20\u2009mg\/kg sildenafil (S group), 20\u2009mg\/kg doxazosin, and 20\u2009mg\/kg sildenafil combination (DS group), respectively via oral gavage. Then, bladder strips were harvested from each animal for isometric tension studies and for real time polymerase chain reaction studies of both AR subtypes and iNOS mRNA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Contractile responses to carbachol and electrical field stimulation at various concentrations\/frequencies showed a significant increase after PUO. Any treatment helped to normalize these increased responses. Alpha 1a and 1d AR subtype expressions were found to be down\u2010 and up\u2010regulated, respectively, in every group with PUO, compared to SHAM group. iNOS expression was similar in D and NT groups and significantly increased in S and DS groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Contractile changes of rat bladder tissue due to PUO were prevented by sildenafil or doxazosin alone or in combination where combination treatment did not provide any additional advantage.
