Valsalva leak point pressure to determine internal sphincter deficiency in stress urinary incontinence.

Introduction: Valsalva leak point pressure (VLPP) represents the global competence of the conjunctive forces around the urethra to support increased pressure from the abdominal cavity with transmission to the bladder. Assessment of VLPP has prognostic meaning, but measurement techniques are still subject to controversy.

Patients And Methods: One hundred and eight consecutive women with no genital prolapse or bladder hyperactivity exclusively presenting with urinary stress incontinence were submitted to VLPP determination during urodynamic evaluation using a rectal and urethral catheter.
