ABSTRACT
Objective To explore the effect of doxazosin on rabbit bladder compliance after partial bladder outlet obstruction. Methods A total of 40 male New Zealand white rabbits were randomized into 4 groups, with 10 rabbits in each group. Partial bladder outlet obstruction was established in groups B and C, while groups A and D underwent the same operation but without partial bladder outlet obstruction. On the day after the operation, groups C and D received oral administration of doxazosin. After 14 weeks, urodynamic examinations were carried out in all groups, and the bladder was weighted after cystectomy. Results Bladder weight was (3.2±0.9) g in group A, (14.1±2.3) g in group B, (5.0±2.0) in group C,and (2.9±0.5) g in group D. The bladder weight in groups B and C increased significantly compared to groups A and D (P<0.01), group B increased significantly over group C (P<0.01), and there was no significant difference between groups A and D (P>0.05).The detrusor leak point pressure was (10.2±2.5) cm H2O in group A, (18.8±6.1) cm H2O in group B, (13.5±4.7) cm H2O in group C,and (11.6±3.6) cm H2O in group D. The detrusor leak point pressure in group B was significantly higher than group A, group D (P<0.01) and group C (P<0.05). There was no significant difference between group A, group C and group D (P>0.05). The bladder compliance was (2.86±0.56) ml/cm H2O in group A, (1.22±0.39) ml/cm H2O in group B, (4.25±2.19) ml/cm H2O in group C,and (2.90±0.53) ml/cm H2O in group D. The bladder compliance was significantly decreased in group B compared to groups A and D (P<0.01). Bladder compliance in group C was significantly higher than in groups A and D (P<0.05), and there was no significant difference between group A and group D (P>0.05). Conclusion Early use of doxazosin can delay the occurrence of lower bladder compliance after partial bladder outlet obstruction, thus protecting the storage function of bladder.
