Primary Outcome Measures
NameTimeMethod
<p>Primary objective:<br /><br>To investigate whether the immunohistochemical characteristics of the bladder<br /><br>wall are different in obstructed bladders showing detrusor overactivity (DO)<br /><br>compared to obstructed bladders without detrusor overactivity and bladder<br /><br>outlet obstruction (BOO) induced urinary retention </p><br>
Secondary Outcome Measures
NameTimeMethod
<p>Secondary objective:<br /><br>-To describe the immunohistochemical characteristics of the bladder wall and<br /><br>urethra<br /><br>-To investigate possible microanatomical connections between nerves, ganglia<br /><br>and interstitial cells in the human bladder<br /><br>-To investigate the distribution of receptors involved in bladder-urethral<br /><br>interactions in relation to bladder outlet obstruction<br /><br>-Mapping of different structures and layers of the bladder during bladder<br /><br>outlet obstruction by using two-photon laser scanning microscopy (TPLSM) </p><br>
