An acquired sensation of wide/smooth vagina: a new classification

To establish a new clinical classification for a wide/smooth vagina.

A prospective multiple time series clinical study without intervention. Vaginal rugation, and vaginal/perineal site-specific defects associated with wide/smooth vagina were used as basic clinical parameters to establish a new classification. One hundred symptomatic women associated with acquired sensations of wide/smooth vagina were enrolled. Main outcome measures were to establish the absence or presence of vaginal columnar rugae and/or site-specific vaginal/perineal/vaginal orifice defects.

The absence of columnar rugation and the absence of vaginal/perineal site-specific defects were identified in 16 subjects; the absence of columnar rugae and the presence of vaginal/perineal site-specific defects were present in 76 women. The presence of columnar rugae and the presence of vaginal/perineal site-specific defects were demonstrated in 5 subjects; and the presence of columnar rugae and absence of vaginal/perineal site-specific defects were recognized in 3 subjects.

A wide vagina classification was developed as a "Category A, Category B, Category C or Category D".
