Methods During surgical prostate resection of 32 BPO patients, mucosal biopsies were collected and analyzed by reverse transcriptase polymerase chain reaction to determine the expression level of beta 3-AR mRNA. First desire to void (FDV) and strong desire to void (SDV), detrusor overactivity (DO), and bladder outlet obstruction (BOO) were measured pre-operatively. Patients with FDVs??201?ml and SDVs?>?301?ml were assigned to the large capacity group (n?=?13). The same patients with positive DO were also assigned to the DO+ group (n?=?11), and those with negative DO were assigned to the DO- group (n?=?21). Finally, patients whose position on the Schafer nomogram was greater than degree V were assigned to the severe BOO group (n?=?17), while those with less than degree IV were assigned to the mild BOO group (n?=?15). Results The expression level of beta 3-AR mRNA was similar in both bladder capacity groups and both DO groups. However, the expression level in the severe BOO group was significantly less than in the mild BOO group (P?=?0.043). Conclusions The expression of bladder mucosal beta 3-AR mRNA was significantly decreased in patients with severe BOO, suggesting that beta 3-ARs might be affected by the degree of BOO. Neurourol.
