[PMID: 34870730 DOI: 10.1007/s00261-021-03361-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 11/18/2021] [Accepted: 11/22/2021] [Indexed: 11/28/2022]
Abstract
PURPOSE This study aimed to explore the value of dynamic magnetic resonance imaging (MRI) before and after operation for pelvic organ prolapse (POP). METHODS Twenty-nine patients with POP (POP group) before and one month after surgery and 12 healthy women (control group) underwent static and dynamic MRI at rest and during straining (Valsalva maneuver). The preoperative MRI images of the POP and control groups were analyzed, and various measurements were recorded. Differences in measurements were compared between the POP and control groups; similarly, changes in measurements before and after operation were compared. RESULTS In the POP group, MRI detected 29 anterior vaginal prolapses, 27 uterine prolapses, 1 rectoceles, and 14 pouch of Douglas hernias. In addition, 27 levator ani muscle defect and 15 pubocervical fascial defect cases were observed. The bladder-pubococcygeal line (B-PCL), uterus-pubococcygeal line (U-PCL), Douglas pouch-pubococcygeal line, the length of the hiatus, the descent of the levator plate, levator hiatus size, levator plate angle, iliococcygeus angle, and urethral inclination angle (UA) were larger in the POP group than in the control group. The pelvic organs' positions returned to normal postoperatively in 9 of 21 cases. The B-PCL, U-PCL, and UA were smaller post-surgery than pre-surgery. CONCLUSIONS Static and dynamic MRI can comprehensively evaluate morphological and functional changes of the pelvic floor postoperatively.

Abstract
INTRODUCTION AND HYPOTHESIS The protocol and analysis methods for the Defining Mechanisms of Anterior Vaginal Wall Descent (DEMAND) study are presented. DEMAND was designed to identify mechanisms and contributors of prolapse recurrence after two transvaginal apical suspension procedures for uterovaginal prolapse. METHODS DEMAND is a supplementary cohort study of a clinical trial in which women with uterovaginal prolapse randomized to (1) vaginal hysterectomy with uterosacral ligament suspension or (2) vaginal mesh hysteropexy underwent pelvic magnetic resonance imaging (MRI) at 30-42 months post-surgery. Standardized protocols have been developed to systematize MRI examinations across multiple sites and to improve reliability of MRI measurements. Anatomical failure, based on MRI, is defined as prolapse beyond the hymen. Anatomic measures from co-registered rest, maximal strain, and post-strain rest (recovery) sequences are obtained from the "true mid-sagittal" plane defined by a 3D pelvic coordinate system. The primary outcome is the mechanism of failure (apical descent versus anterior vaginal wall elongation). Secondary outcomes include displacement of the vaginal apex and perineal body and elongation of the anterior wall, posterior wall, perimeter, and introitus of the vagina between (1) rest and strain and (2) rest and recovery. RESULTS Recruitment and MRI trials of 94 participants were completed by May 2018. CONCLUSIONS Methods papers which detail studies designed to evaluate anatomic outcomes of prolapse surgeries are few. We describe a systematic, standardized approach to define and quantitatively assess mechanisms of anatomic failure following prolapse repair. This study will provide a better understanding of how apical prolapse repairs fail anatomically.

Abstract
INTRODUCTION AND HYPOTHESIS To describe the impact of native tissue vaginal reconstruction on pelvic anatomy using dynamic magnetic resonance imaging. METHODS This prospective single-cohort observational study involved women undergoing native tissue reconstruction with intraperitoneal vaginal vault suspension for pelvic organ prolapse. Concomitant procedures such as hysterectomy, midurethral sling, and anterior or posterior colporrhaphy were allowed. Enrolled participants underwent dynamic pelvic imaging pre- and postoperatively. Radiographic and anatomic measurements were compared. Secondary outcomes included validated patient questionnaires. RESULTS Fourteen participants were included in the analysis. The mean age was 62 years; all participants were Caucasian. Most participants had stage III pelvic organ prolapse. Significant improvements were noted in several radiographic measurements. The average H-line (representing levator hiatus width) with straining maneuvers improved following surgery (7.2 cm preoperatively vs. 6.6 cm postoperatively, p = 0.015). The average M-line (representing levator muscular descent) improved significantly with both straining (4.0 cm preoperatively vs. 3.0 cm postoperatively, p < 0.001) and defecatory maneuvers (6.2 cm preoperatively vs. 5.2 cm postoperatively, p = 0.001). The average size of cystocele improved from 5.6 cm (moderate) preoperatively to 0.7 cm (absent descent) postoperatively (p < 0.001). The average descent of the vaginal apex with defecation preoperatively was 3.0 cm (moderate) and 0 cm (absent descent) postoperatively (p = 0.003). Posterior compartment descent with defecation did not change following surgical intervention (5.8 cm preoperatively vs. 5.2 cm postoperatively, p = 0.056). Pelvic Organ Prolapse Quantification measurements improved in all compartments, and Pelvic Floor Distress Inventory-20 scores improved significantly following surgery (102 preoperatively vs. 30 postoperatively, p < 0.001). CONCLUSIONS Native tissue reconstruction with intraperitoneal vaginal vault suspension resulted in significant anatomic improvements, as defined by physical examination and dynamic magnetic resonance imaging.

Abstract
Introduction An increasing number of women are presenting with symptoms after the placement of mesh implants for prolapse which may be attributable to a mesh implant complication. MRI imaging can be used to evaluate abdominally placed mesh but there is no published research evaluating the use of MRI in this group of women. The objective of our study was to report our experience as a tertiary centre in evaluating abdominal mesh with MR imaging and the agreement of MR reports with surgical findings. Study design A retrospective observational cohort study (Canadian Task Force classification II-2) of all women referred to our tertiary unit who underwent an MR scan for investigation of symptoms of mesh complication following an abdominally placed mesh implant between June 2006 and September 2018 was performed. The reports of MR images were compared with the findings at surgery. Results MR scan was performed in 87 with suspected mesh complications. MR scan detected mesh failure in 42.1% of women (37/87), infection in 12.6% (11/87), compression in 2.3% (2/87), exposure in 12.6% (11/88), bowel extrusion in 2.3% (2/87) and inflammation in 11.5% (10/87). Agreement between MR scan report and surgical diagnosis was almost perfect for mesh failure, infection and compression, whilst agreement was only moderate for mesh erosion and signs of inflammation (failure κ = 0.97, infection κ = 0.94, compression κ = 1.0, exposure κ = 0.58 and inflammation κ = 0.24). Conclusion These data provide information on the role of MR imaging in the investigation of women presenting with suspected intra-abdominal POP mesh complications including recurrence.

Abstract
Abdominal wall hernia is a recurrent issue world-wide and requires the implantation of over 1 million meshes per year. Because permanent meshes such as polypropylene and polyester are not free of complications after implantation, many mesh modifications and new functionalities have been investigated over the last decade. Indeed, mesh optimization is the focus of intense development and the biomaterials utilized are now envisioned as being bioactive substrates that trigger various physiological processes in order to prevent complications and to promote tissue integration. In this context, it is of paramount interest to review the most relevant bio-functionalities being brought to new meshes and to open new avenues for the innovative development of the next generation of meshes with enhanced properties for functional abdominal wall hernia repair.

Abstract
Pelvic organ prolapse (POP) is a disabling disorder in women characterized by a loss of pelvic floor support, leading to the herniation of the uterus into or through the vagina. POP is a complex problem that likely involves multiple mechanisms with limited therapies available, and is associated with defects in connective tissue including elastic fibers. This study was designed to investigate the expression of fibulin-5 and lysyl oxidase-like 1 (LOXL1) in the cardinal ligament in samples taken from the POP group compared to the non-POP group. Specimens were obtained during abdominal hysterectomy from the cardinal ligament of 53 women with POP and 25 age- and parity- matched women with non-POP among post-menopausal women with benign gynecologic pathology. Protein expression was evaluated using the immunohistochemical staining method. For statistical analyses, chi-square test and Spearman's correlation were used with the statistical package SPSS13.0 system. Our results showed that both fibulin-5 and LOXL1 expressions were decreased in the cardinal ligament in the POP group compared to the non-POP group (P < 0.05). The expression of fibulin-5 and LOXL1 were correlated closely with the stage of POP, accompanied by stress urinary incontinence and frequency of vaginal delivery (P < 0.05), but had no relationship with post-menopausal state (P > 0.05). The expression of fibulin-5 was positively associated with LOXL1 in POP (P < 0.05). We conclude that changes in fibulin-5 and LOXL1 expression may play a role in the development of POP.

Abstract
INTRODUCTION AND HYPOTHESIS We compared two surgical approaches in patients with symptomatic prolapse of the vaginal apex with normal controls by analyzing pelvic landmark relationships measured using magnetic resonance imaging (MRI) before and after surgery. METHODS In this prospective multicenter pilot study involving 16 participants, nulliparous controls (n = 6) were compared with ten parous (3.0 ± 1.0) women with uterine apical prolapse equal to or greater than stage 2. Group A (n = 5) underwent abdominal sacral colpopexy with monofilament polypropylene mesh and group B (n = 5) with vaginal mesh kit repair (Total ProLift). Subtotal hysterectomy was performed in all group A and no group B women. All patients underwent preoperative and 3-month postoperative Pelvic Organ Prolapse Quantification (POP-Q) and dynamic MRI. Comparison of MRI pelvic angles and distances was performed and analyzed by Mann-Whitney rank sum test and chi-square test. RESULTS Vaginal apical support is similar at 3 months for abdominal sacral colpopexy (ASCP) and ProLift by POP-Q examination and MRI analysis. In both treatment groups, the postoperative POP-Q point C and MRI parameters were similar to nulliparous controls at 3 months. CONCLUSIONS Anatomic outcomes for ASCP compared with ProLift were similar at 3 months in terms of vaginal apical support by POP-Q and MRI analysis. Continued comparative analysis of postoperative support with objective imaging seems warranted.
