Patients who had the operation of "laparoscopic lateral mesh suspension" for apical prolapse will have magnetic resonance imaging preoperatively and at postoperative 6th month

Multiparous, sexually active participants who have grade 0 or 1 (asymptomatic if exists) prolapse will have magnetic resonance imaging as a control group

MRI will be performed using a standard body spiral in the supine position with 5 mm section thickness, on the axial, coronal and sagittal planes and the diffusion weighted images acquired will be evaluated by a specialised radiologist who will be blind to the participants.

From the images obtained in the sagittal plane, the vagina, which will be observed as a high signal intensity linear structure in T2A images, and the levator plate extending as a flow-signal intensity flat structure in T1A images, will be evaluated.

The angles between the pubococcygeal line and lower vaginal segment (angle A), between the levator plate and the pubococcygeal (angle B) and between lower and upper vaginal segments (angle C) will be measured.

The distance between the posterior vaginal fornix and the midpoint of the anterior side of the 2nd vertebra will be measured in the mid-sagittal plane (PF-S2). The distance between the right spina ischiadica and right vaginal fornix (RSI-RF), and, the distance between the left spina ischiadica and left vaginal fornix (LSI-LF) will be measured on T2A images acquired in the axial plane.

Michigan Incontinence Severity Index (M-ISI) scale will be used to assess subjective outcome including urge symptoms. This scale has ten items, consisting of a total M-ISI domain (the sum of items 1-8) and a distinct Bother domain (the sum of items 9 and 10). The total M-ISI score consists of three subdomains (items 1-3 for stress urinary incontinence [SUI], items 4-6 for urge urinary incontinence [UUI], and items 7 and 8 for Pad usage [PU]. The responses for each item range from 0 to 4 on a Likert-type scale, with higher values representing greater symptoms and greater bother. Total domain and subdomain scores are obtained by simply adding the respective answers. The minimally important difference has been determined for the following domains/subdomains: total M-ISI (4 points), SUI (2 points), UUI (2 points), and PU (1 point).
