The purpose of the study is to compare the effect of solifenacin succinate between frequent micturition patients with urgency and those without urgency.


Eligibility Criteria:
Inclusion Criteria:

* For the without-urgency group:

  * urinary frequency ≥ 8 micturitions per 24 hours no urgency on voiding diary (1 or 2 on a 5 urgency scale)
* For the with-urgency group:

  * urinary frequency ≥ 8 micturitions per 24 hours symptoms of urinary urgency≥ 2/day on the voiding diary (3 to 5 on a 5 urgency scale)
* Symptoms lasting for more than 3 months

Exclusion Criteria:

* Clinically significant stress incontinence as determined by the investigator; for female patients, clinically significant stress incontinence confirmed by a cough provocation test
* Total daily urine volume of \> 3000 mL as verified on the micturition diary before randomization
* Significant hepatic or renal disease, defined as having twice the upper limit of the reference ranges for serum concentrations of aspartate aminotra
* Any condition that is a contraindication for anticholinergic treatment, including uncontrolled narrow-angled glaucoma, urinary retention or gastric retention
* Symptomatic acute urinary tract infection (UTI) during the run-in period
* Recurrent UTIs defined as having been treated for symptomatic UTIs \> 4 times in the last year
* Diagnosed or suspected of interstitial cystitis
* Uninvestigated hematuria or hematuria secondary to a malignant disease
* Clinically significant bladder outlet obstruction defined by clinical symptoms and investigator's opinion according to local standard of care (residual urine\> 100mL of functional bladder capacity)
* Patients with marked cystocele or other clinically significant pelvic prolapse
* Treatment within 14 days preceding randomization, or expected to initiate treatment during the study with:

  * Any anticholinergic drugs other than a randomized trial drug
  * Any drug treatment for overactive bladder. Estrogen treatment started more than 2 months prior to inclusion is allowed
* On an unstable dosage of any drug with anticholinergic side effects, or expected to start such treatment during the study
* Receipt of any electrostimulation or bladder training within 14 days before randomization, or expected to start such treatment during the study

* Sexually active females of childbearing potential not using reliable contraception for at least 1 month prior to the start of the study and not agreeing to use such methods during the entire study period and for at least 1 month thereafter. Reliable contraceptive methods are defined as intrauterine devices (IUDs), combination type contraceptive pills, hormonal implants, double barrier method, injectable contraceptives and surgical procedures (tubal ligation or vasectomy)
* Patients who have bladder cancer or prostate cancer
* Treatment with potent CYP3A4 inhibitors, such as cyclosporine, vinblastine, macrolide antibiotics (e.g. erythromycin, clarithromycin, azithromycin) or antifungal agents (e.g. ketoconazole, itraconazole, micronazole)
* Patients who have neurological disease
* Patients who have psychological disease
