摘要: La physiopathologie des prolapsus genitaux n’est a ce jour qu’incompletement elucidee. Le deficit en muscle lisse de la paroi vaginale ete demontre. Il est possible que les caracteristiques soient differentes chez patientes ayant un recidive. L’objectif cette etude comparer proportion anterieure une cystocele recidivee ou operee pour premiere fois par rapport groupe temoin sans prolapsus. Des echantillons du cul-de-sac vaginal anterieur ont preleves 11 et huit operees d’une hysterectomie Une deuxieme analyse compare cinq cystoceles recidivees six fois. coloration trichrome Masson utilisee determiner distribution collagene dans matrice extracellulaire musculeuse quantifier le collagene. immunohistochimique utilisant anticorps anti-alpha actine identifier cellules musculaires lisses. morphometrique realisee relative vaisseaux. etait significativement diminuee au (41,9 vs 61,9 %, p = 0,0005 [IC 95 %: 10,8–28,9]). augmentee (56,8 35 0,0002 12,9–30,8]). vaisseaux sanguins comparable (2,2 3,4 0,09 −2,8–0,3]). n’existait pas difference proportions lisse, (respectivement 40 44 0,62 −22,7–14,33], 59,6 53,4 0,46 −12,1–24,4] 2,1 2,3 0,69 −1,6–1,1]). Les alterations morphometriques retrouvees sont faveur reparations prothetiques. etudes ulterieures sur reversibilite ces anomalies seraient necessaires afin d’orienter choix type prothese, resorbable non. En revanche, l’histologie ne semble predictive caractere recidive non morphometrie tissu considerablement alteree temoin. opere
