Arms Assigned Interventions
Experimental: 1.tamsulosin + solifenacin Drug: Solifenacin
Other Name: Vesicare

Detailed Description:
This is a multi-center study to evaluate the efficacy, safety, and persistency of solifenacin treatment in male patients with persistent OAB symptoms of urinary frequency and urgency with/without urgency incontinence who are receiving tamsulosin monotherapy for LUTS at a stable dose for 4 weeks in real life practice. Also proportion of patients and predictive factors with persistent OAB symptoms after tamsulosin monotherapy will be investigated.

Ages Eligible for Study:   45 Years and older
Genders Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • IPSS ≥ 12
  • Symptoms of OAB as verified by the V8 (≥8)
  • Symptoms of OAB as verified by the screening 3-day bladder diary, defined by:

    • Mean urinary frequency ≥8 times/24 hours
    • Mean number of micturition-related urgency episodes ≥3 episode/24 hours (with a Urinary Sensation Scale rating of ≥3 marked for the corresponding micturition in the bladder diary)

Exclusion Criteria:

  • Treatment within the 14 days preceding treatment with any alpha blocker drugs
  • A known history of bladder outlet obstruction due to: bladder neck contracture, clinical suspicion of prostate carcinoma, mullerian duct cysts, urethral obstruction due to stricture/valves/sclerosis or urethral tumor
