title: Postoperative vesicourethral function after ultrasonic surgical aspirator-assisted surgery of gynecologic malignancies.
abstract: OBJECTIVE
  The most concerned complication of radical hysterectomy includes the vesicourethral dysfunction. The use of Cavitron ultrasonic surgical aspirator (CUSA) may preserve the blood supply to the urinary tract even during the surgical procedure, prompting us to evaluate the advantage of using the CUSA with the complication.
  
  
  METHODS
  We analyzed medical profiles of a total of 275 patients with pelvic lymphnode dissection (137 subjects with radical hysterectomy and 138 with modified radical hysterectomy).
  
  
  RESULTS
  The use of CUSA in radical (formal or extended) hysterectomy reduced the period for the residual urine to become <50 ml in cases of advanced stages equal and over Ib of uterine cervical cancers.
  
  
  CONCLUSIONS
  The CUSA may be more effective in the prevention of radical hysterectomy for its major complication, vesicourethral dysfunction. The CUSA-assisted surgery may be applicable, primarily, for advanced uterine cancer.
