  Purpose

The injection of botulinum neurotoxin A into the prostate represents an alternative, minimal invasive treatment in patient with lower urinary tract symptoms (LUTS) associated to benign prostatic hyperplasia (BPH).

Objective: To evaluate the effectiveness of BTA in treating patients with symptomatic BPH and unsatisfactory response to combined medical therapy.

Primary Outcome Measures:
  • evaluation of symptomatic improvement after treatment as measured by the IPSS score. A successful outcome was defined as a reduction of IPSS score of > 50% from baseline. [ Time Frame: 3 month ]

Secondary Outcome Measures:
  • safety and tolerability of treatment [ Time Frame: 3 month ]
    Quality of life improvement as measured by QoL score, changes in prostate volume, total PSA levels, maximal flow at uroflowmetry, post-void residual urine,maximal cystometric capacity, Bladder Outlet Obstruction Index, sexual modifications evaluated by International Index of Erectile Function.


Enrollment: 33

Arms Assigned Interventions
Experimental: BOTOX Drug: BOTOX
Botulinum Toxin type A, 200-300 UI dilued in 6 ml of saline solution
