Objective:
To evaluate the efficacy and safety of Tolterodine Tartrate combined with the alpha-receptor blocker in the treatment of benign prostatic hyperplasia with detrusor overactivity (BPH-DO).
Methods:
A total of 113 patients with BPH-DO were randomly assigned to receive Tolterodine Tartrate combined with Cardura (Group A) and Cardura alone (Group B), both for 12 weeks. Then we recorded and compared their average 24 h urinary frequency, IPSS and QOL score, maximum urinary flow rate, residual urine volume and urinary retention times before and after the treatment.
Results:
After the treatment, Group A showed significantly better improvement in the average 24 h urinary frequency and scores on IPSS and QOL than Group B. No significant differences were found between the two groups in the maximum urinary flow rate and residual urine volume. No acute urinary retention occurred in either group.
Conclusion:
The combined use of Tolterodine Tartrate and the alpha-receptor blocker can effectively relieve the symptoms of dysuria, urinary frequency and urinary urgency in patients with BPH-DO, with neither significant adverse effects on the maximum flow rate and residual urine volume nor increase in the incidence of acute urinary retention.

α1-blockers: These drugs inhibit α1-adrenoceptors on smooth muscle cells, resulting in vasodilation. This vasodilation lowers blood pressure, making α1-blockers valuable in treating hypertension. Additionally, α1-blockers effectively address urinary obstruction...
