Four weeks following surgery, their voiding behavior was measured in a metabolic cage. BOO\u2010rats were administered silodosin, prazosin or vehicle for 2 weeks subcutaneously using osmotic pump. At the post\u2010drug condition, voiding behavior was measured again. The L6 spinal cord was removed and immunostained using anti c\u2010Fos antibody. The rats were also performed continuous cystometry with saline without anesthesia or restraint at the pre\u2010 and post\u2010drug conditions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Metabolic cage study showed the voiding behavior of BOO\u2010rats was characterized by increase in frequency of urination and decrease in volume voided. Cystometric evaluation also showed the significant increase both in the number of successive voiding contraction and in contraction pressure. The administration of silodosin or prazosin significantly decreased urinary frequency and the number of micturition reflex but affected neither bladder contraction pressure nor residual volume. The number of c\u2010Fos\u2010positive cell significantly increased in BOO\u2010rats, while significantly decreased in those receiving \u03b1l\u2010AR antagonists.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The present study demonstrates that \u03b11\u2010AR antagonists silodosin and prazosin have an inhibitory effect on afferent input from the lower urinary tract independently of reducing urethral resistance, and thereby reduce the storage dysfunction secondary to BOO. This result suggests that \u03b1l\u2010AR, particularly \u03b1lA\u2010AR, may play an important role in the activation of the afferent pathway. Neurourol.
