[25 years of Integral Theory by Petros : What remains and what's next?].

BACKGROUND

The Integral Theory (IT) states that urinary stress and urge symptoms mainly arise from lax suspensory ligaments, which are a consequence of altered collagen/elastin. Four important muscle groups (pubococcygeal muscle, levatorplate, longitudinal muscle of the anus, and the puborectalis muscle) are only able to guarantee the opening and closure mechanism of the bladder, the urethra and the anal tube if the suspensory ligaments are intact. The first practical application of the IT was the repair of the pubourethral ligament (PUL) known as tension-free vaginal tape (TVT).

OBJECTIVES

What is the practical impact of the IT today? Do lax suspensory ligaments play a role in stress and urge urinary incontinence, fecal incontinence, voiding difficulties, and pelvic pain?

MATERIALS AND METHODS

Evaluation of the literature, data, and experiences concerning IT.

RESULTS

The pathophysiology of pelvic floor disorders has been widely proven and surgical concepts were developed to reconstruct the ligaments with the result of regaining function. Suburethral tapes are accepted as the standard of care for urinary stress incontinence. In addition, the correction of cervical ring defects, the lateral and central cystoceles, the uterosacral ligaments, the perineal body, and the rectovaginal fascia were adapted and newly developed with the aim of alleviating symptoms. Newly published data prove the cure of symptoms in a high percentage of cases. The complex conditions and function of the pelvic floor can be understood much better by using the diagnostic algorithm and with knowledge of the basic pathophysiology.

CONCLUSION

The basic IT message: repair the structure (ligaments) and you will restore the function is true for all pelvic floor ligaments.
