title: [Diagnosis of intrinsic urethral sphincter insufficiency in women].
abstract: OBJECTIVE
  Evaluation of intrinsic sphincter deficiency (ISD) according to the urethral leak point pressure in female population with stress urinary incontinence.
  
  
  METHODS
  Prospective clinical study.
  
  
  METHODS
  Department of Urology, Jessenius School of Medicine Comenius University Martin, Slovak Republic.
  
  
  METHODS
  Study population compromise of 204 females with lower urinary tract symptoms. Exclusion criteria were neurogenic bladder and unstable bladder. Valsalva leak point pressures were evaluated (VLPP). ISD was defined if VLPP below 65 cm H2O has been occurred. Pad weighing test (PWT) was positive after leakage of 2 g per hour and more.
  
  
  RESULTS
  Stress urinary incontinence was in 134 and continence in 70 cases (control group). The first stage of incontinence was in 83, the second stage in 45 and the third stage in 6 cases of incontinence group. ISD has been occurred in 14 cases (10.5%), 8 cases with the second stage and 6 cases with the third stage. The best correlation was between VLPP and PWT, symptoms of incontinence and age of patients. All ISD cases underwent antiincontinent surgery with urethral suspension, some years ago.
  
  
  CONCLUSIONS
  ISD has been risen in the second stage (6%) and the third stage (4.5%), also, in the female population with stress urinary incontinence.
