title: Clitoral blood flow changes after surgery for stress urinary incontinence: pilot study on TVT Versus TOT procedures.
abstract: OBJECTIVE
  To study the effects of mini-invasive surgery using the tension-free vaginal tape (TVT) procedure and the transobturator tape (TOT) procedure in modifying clitoral blood flow in women affected by stress urinary incontinence.
  
  
  METHODS
  The setting of the prospective open clinical study was the Urogynecologic Service of the Department of Microbiological and Gynecological Science, University of Catania School of Medicine (Catania, Italy). A total of 105 women underwent surgery; 42 (mean age 52.8 years) and 63 (mean age 53.9 years) were treated with TVT and TOT, respectively. Each woman underwent translabial color Doppler ultrasonography to measure the resistance index, pulsatility index, peak systolic velocity, and end-diastolic velocity of the clitoral arteries, before and 6 months postoperatively.
  
  
  RESULTS
  In the TVT group, the mean pulsatility index and mean peak systolic velocity were significantly lower and the mean resistance index was significantly greater compared with the pretreatment values (P <0.5). In the TOT group, each color Doppler measurement was similar to that obtained at baseline (P = NS).
  
  
  CONCLUSIONS
  The different vaginal approach for these two surgical methods influenced clitoral blood flow. Our data could add new information about sexual behavior after incontinence treatment, particularly the impact of clitoral blood flow changes.
