title: OnabotulinumtoxinA intravesical treatment in patients affected by overactive bladder syndrome: best practice in real-life management.
abstract: OBJECTIVE
  We evaluated intradetrusorial OnabotulinumtoxinA (Onabot/A) treatment protocols in patients with idiopathic overactive bladder (OAB), in order to assess the care of patients before, during and after treatment.
  
  
  METHODS
  In 64 OAB patients injected with Onabot/A, we reviewed the length of the hospital stay, frequency of catheterization, frequency of intraoperative and postoperative complications, and patients' satisfaction to the proposed treatment protocol (as assessed by VAS). We also compared the results of the 3-day voiding diary, uroflowmetry with postvoid residual urine (PVR) and VAS to score the bother of urinary symptoms on quality of life (QoL) before and after treatment.
  
  
  RESULTS
  Twenty-one patients were firstly treated in an 'inpatient' setting. The mean ± SD duration of hospitalization and catheterization was 39.4 ±12.6 and 37.8 ± 10.6 h, respectively. The mean ± SD VAS values of treatment satisfaction and of bother of urinary symptoms on QoL were 6.3 ± 1.1 and 8.2 ± 1.3, respectively. The mean ± SD PVR value was 74.3 ± 15.2 ml. Frequency of UTIs was 2.4 ± 1.6. Forty-three patients were treated on an outpatient basis; the mean ± SD duration of catheterization, the 'outpatient' stay and the mean ± SD frequency of UTIs were lower than those of patients treated in an inpatient setting. The mean ± SD VAS value to score QoL was high.
  
  
  CONCLUSIONS
  Intradetrusorial Onabot/A injection is a simple and fast procedure that can be easily carried on in an outpatient setting under local anesthesia, with low rates of intraoperative and postoperative complications.
