[Vaginal laxity: semiology, diagnosis and treatments].

OBJECTIVES: Vaginal laxity concerns 24 to 38% of women but it's still poorly understood and studied. The objective of this study is to do an inventory of current scientific knowledge about its definition, its diagnostic criteria, and treatments.

METHODS: We conducted a non systematic review of literature including original articles in French and English about the definition, diagnostic criteria and treatments of vaginal laxity using data bases such as Cochrane, Embase, Medline, PubMed et Science Direct.

RESULTS: It is a feeling of excessive looseness that can alter the quality of sexual intercourses. The main risk factor is vaginal delivery. The feeling of vaginal laxity appears to be linked to an excessive distensibility of the levator ani muscle that can be evaluated during physical examination by the measure of the genital hiatus and the perineal body (GH and PB measures from the POP-Q classification) during vasalva or by the measure of genital hiatus area by translabial sonography during valsalva. Although pelvic muscle training is currently prescribed as a first line treatment, data are limited to confirm its effectiveness in this affection. Colpoperineorraphy with levator ani myorraphy which was mostly evaluated in case of genital prolapse is associated with a high success rate but is at risk of dyspareunia. New non-surgical treatments such as radiofrequency and vaginal laser seems to lead to lower success rate than surgical treatments but they are less invasive. Their effectiveness and long-term effects are still unknown which restrict their application in this condition.

CONCLUSION: Vaginal laxity is a frequent condition that impacts on the quality of life and sexual function. Further studies should be conducted to better understand its physiopathology and the optimal treatment.
