For many years, researchers on this field have suffered from the lack of an efficient method for describing pelvic organ
prolapse
. Struggling to solve this problem, the International Continence Society has proposed a pelvic organ
prolapse
quantification (POP-Q) system [Bump RC, Mattiasson A, Bo K, Brubaker LP, DeLancey JO, Klarskov P, Shull B, Smith
ARB
, Am J Obstet Gynecol, 175(1):1956-1962, 1996], which was validated as a precise and reproducible technique for describing pelvic organ position. However, even though very precise at describing pelvic organ position, our critic to this system is its limited ability to quantify the
prolapse
itself, since it still classifies
prolapse
into four grades, almost the same way as Baden and Walker did in 1972. As a result, the same grade can include a wide
prolapse
intensity range. The objective of this paper is to propose a method that makes POP research more efficient by directly measuring
prolapse
as a continuous variable that requires lesser number of subjects in order to achieve statistical significance.

Female pelvic organ
prolapse
refers to the descent of the pelvic organs towards or through the vagina. The similarities between vaginal
prolapse
and herniae in their aetiology and treatment make this an interesting area for all those operating in the pelvis. It is a common condition with prevalence estimates varying from 2% for symptomatic
prolapse
to 50% for asymptomatic
prolapse
[Samuelsson EC, Arne Victor FT, Tibblin G, Svardsudd KF. Signs of genital
prolapse
in a Swedish population 20 to 59 years of age and possible related factors. Am J Obstet Gynecol 1999;180:299-305]. Approximately 50% of parous women will have some degree and only 10-20% of these seek medical help [Beck RP. Pelvic relaxation
prolapse
. In: Kase NG, Weingold AB, editors. Principles and practice of clinical gynecology. New York: John Wiley; 1983. p. 677-85]. The lifetime risk for surgery for
prolapse
has been estimated to be around 11.1%, and 30% will undergo re-operation for recurrent
prolapse
[Olsen AL, Smith VJ, Bergstrom JO, Colling JC, Clark AL. Epidemiology of surgically managed pelvic organ prolapsed and urinary incontinence. Obstet Gynecol 1997;89:501-6]. The aetiology of
prolapse
is multifactorial. Advancing age, parity and collagen weakness are all quoted as significant predisposing factors [Olsen AL, Smith VJ, Bergstrom JO, Colling JC, Clark AL. Epidemiology of surgically managed pelvic organ prolapsed and urinary incontinence. Obstet Gynecol 1997;89:501-6; Maclennan AH, Taylor AW, Wilson, Wilson D. The prevalence of pelvic floor disorders and their relationship to gender, age, parity and mode of delivery. Br J Obstet Gynaecol 2000;107:1460-70]. Pathophysiological mechanisms that have been proposed include pelvic floor denervation, direct trauma to the pelvic floor musculature, abnormal synthesis and degradation of collagen and defects in endopelvic fascia [Al-Rawi ZS, Al-Rawi ZT. Joint hypermobility in women with genital
prolapse
. Lancet 1982;I:439-41; Gilpin SA, Gosling JA. Smith

The procedure of choice for reconstructive surgery to the vagina should be tailored to the individual patient and be of low morbidity and mortality, but at the same time with long-term durability.
