Center for Pelvic Physiology

The Center for Pelvic Physiology uses technology to evaluate patients with fecal and urinary incontinence, constipation, pelvic floor disorders, urinary tract disorders and anal and rectal tumors or fistulas. Established in 1995, we recently expanded our services and moved into a new state-of-the-art facility.

A specially trained nurse and board-certified colorectal surgeons or urogynecologists conduct comprehensive evaluations for our patients. We offer biofeedback therapy as well as innovative surgical therapies for fecal and urinary incontinence. Our patients who don't respond to conventional care may participate in clinical trials or research projects that test new, experimental therapies.

Procedures Offered

Services offered at the center include:

  • Anorectal Manometry — Measures internal and external sphincter pressures, rectal sensation, rectal volume capacity and recto-anal inhibitory reflex (RAIR), which can confirm or exclude a diagnosis of Hirschsprung's disease
  • Puborectalis Muscle Fiber Recruitment — Measures neuromuscular activity that helps diagnose pelvic floor dysfunction
  • Pudendal Nerve Testing — Evaluates the presence and response rate of the pudendal nerve, which may impact fecal incontinence
  • Endoanal Ultrasound — Evaluates the integrity of internal and external sphincter for incontinence and fistula-in-ano
  • Endorectal Ultrasound — Evaluates the depth of rectal tumors for staging
  • Biofeedback — Functional training of rectum, anal sphincter and pelvic floor muscles to treat fecal incontinence and constipation
  • Urodynamic Testing — This includes:
    • Cystoscopy — Evaluates the urethra and bladder for intrinsic lesions by direct visualization
    • Cystometrogram (CMG) — Pressure filling study used to evaluate bladder capacity, sensation and urinary incontinence
    • Urethral Pressure Profile (UPP) — Evaluates urethral closure pressure, a measure of severity of stress incontinence
