Surgical anatomy of the mid-vagina.

AIM: The mid-vagina (MV) represents Level II of the vagina. The surgical anatomy of the MV has not been recently subject to a comprehensive examination and description. MV surgery involving anterior and posterior colporrhaphy represents a key part of surgery for a majority of pelvic organ prolapse (POP). METHODS: Literature review and surgical observations of many aspects of the MV were performed including MV length and width; MV shape; immediate relationships; histological analysis; anterior and posterior MV prolapse assessment and anterior MV surgical aspects. Unpublished pre- and postoperative quantitative data on 300 women undergoing posterior vaginal compartment repairs are presented. RESULTS: The MV runs from the lower limit of the vaginal vault (VV) to the hymen. Its length is a mean of 5 cm. Its shape in section overall is a compressed rectangle. Its longitudinal shape is created by its anterior and posterior walls being inverse trapezoid in shape. Histology comprises three layers: (i) mucosa; (ii) muscularis; (iii) adventitia. MV prolapse staging uses pelvic organ prolapse quantification (POP-Q). Anterior MV prolapse can be quantitatively assessed using POP-Q while posterior MV prolapse can be assessed with POP-Q or PR-Q. Around 50% of both cystocele and rectocele are due to VV defects. POP will increase anterior MV width and length. Native tissue anterior colporrhaphy is the current conventional repair with mesh disadvantages outweighing advantages. Posteriorly, Level II (MV) defects are far smaller (mean 1.3 cm) than Level I (mean 6.0 cm) and Level III (mean 2.9 cm). CONCLUSION: An understanding of the surgical anatomy of the MV can assist anterior and posterior colporrhaphy. In particular, if VV support is employed, the Level II component of a posterior repair should be relatively small.

Surgical anatomy of the vaginal vault.

AIM: Vaginal vault (VV) surgery should be a key part of surgery for a majority of pelvic organ prolapse (POP). The surgical anatomy of the VV, the upper most part of the vagina, has not been recently subject to a dedicated examination and description. METHODS: Cadaver studies were performed in (i) 10 unembalmed cadaveric pelves (observation); (ii) 2 unembalmed cadaveric pelves (dissection); (iii) 5 formalinized hemipelves (dissection). The structural outline and ligamentous supports of the VV were determined. Further confirmation of observations in post-hysterectomy patients were from a separate study on 300 consecutive POP repairs, 46% of whom had undergone prior hysterectomy. RESULTS: The VV is equivalent to the Level I section of the vagina, measured posteriorly from the top of the posterior vaginal wall (apex or highest part of the vagina) to 2.5 cm below this point. It comprises the anterior fornix (through which cervix protrudes or is removed at hysterectomy), posterior fornix and two lateral fornices. Before hysterectomy, the posterior aspects of the cervix and upper vagina are supported by the uterosacral (USL) and cardinal ligaments (CL), the distal segments of which fuse together to form a cardinal-uterosacral ligament complex (cardinal utero-sacral complex), around 2-3 cm long. Post---hysterectomy, there is some residual USL support to the anterior fornix but the posterior fornix has no ligamentous support and is thus more vulnerable to prolapse. CONCLUSION: Effective management of VV prolapse will need to be part of most POP repairs. Enhanced understanding of the surgical anatomy of the vaginal vault allows more effective planning of those POP surgeries.

Surgical anatomy of the vaginal introitus.

AIM: The vaginal introitus is the entrance to the vagina, encompassing the anterior and posterior vestibules and the perineum. The surgical anatomy of the vaginal introitus, the lowest level of the vagina, has not been subject to a recent comprehensive examination and description. Vaginal introital surgery (perineorrhaphy) should be a key part of surgery for a majority of pelvic organ prolapse. METHODS: Cadaver studies were performed on the anterior and posterior vestibules and the perineum. Histological studies were performed on the excised perineal specimens of a cohort of 50 women undergoing perineorrhaphy. Included are pre- and postoperative studies which were performed on 50 women to determine the anatomical and histological changes achieved with a simple (anterior) perineorrhaphy. RESULTS: The vaginal introitus is equivalent to the Level III section of the vagina, measured posteriorly from the clitoris to the anterior perineum then down the perineum to the anal verge. The anterior and posterior vestibules, with nonkeratinizing epithelium, extend laterally to the keratinized epithelium of the labia minora (Hart's line). The anterior vestibule has six anatomical layers while the posterior vestibule has three. The perineum has an inverse trapezoid shape. Perineorrhaphy specimens were a mean 2.9 cm wide and 1.6 cm deep. They show squamous epithelium with loose underlying connective tissue. There were no important structures seen histologically, for example, ligaments or muscles. Microscopically, only 6 (12%) were completely normal with 44 (88%) showing minor changes including inflammation and scarring. Considerable anatomical benefits were achieved with such a perineorrhaphy including a 27.6% increase in the perineal length and a 30.8% reduction in the genital hiatus. CONCLUSION: An understanding of the anatomy and histology of the vaginal introitus can assist with performing a simple and effective perineorrhaphy, the main surgical intervention at the vaginal introitus.

What if there were no tapes?

It is possible that the controversy involving prostheses implanted into women with pelvic floor problems might result in the majority of, or even all such products being restricted, banned or withdrawn in certain jurisdictions. A clear distinction between "tapes" for urinary incontinence and "mesh" for prolapse has been made in the enquiries and subsequent rulings in Australia and New Zealand. Transvaginal "mesh" will be unavailable with the range of "tapes" much more restricted in those countries from January 2018. The Chair of the all-party parliamentary group on surgical mesh implants in the United Kingdom was reported as describing the New Zealand announcement as "hugely significant" and "it's precisely what we've been calling for the UK." The title of this article has changed from a hypothetical piece to a potential reality review. Where does that leave the clinicians treating stress urinary incontinence (SUI) and the large number of female sufferers? "Tapes" (synthetic midurethral slings-MUS) have become very popular over the last 20 years since their original development and introduction in Scandanavia. Evidence-based medicine has shown their advantages over previous surgeries, in terms of ease of use, safety and efficacy. This article outlines the options which countries potentially rejecting the use of tapes, must now resort to for women with SUI. Those countries considering such action need the note of caution that none of the options are as good as tapes.

Posterior vaginal compartment repairs: Does vaginal vault (level I) fixation significantly improve the vaginal introital (level III) repair?

INTRODUCTION: Limited data exist associating vaginal vault and introital defects before and after posterior repairs (PR). We hypothesize: (i) a positive association between the size of vaginal vault and introital defects preoperatively; and (ii) a positive association between the reduction of these defects postoperatively if vault fixation (sacrospinous colpopexy-SSC) is used with the PR. METHODS: In a cross-sectional study of 300 consecutive PRs, the following were measured pre- and immediately postoperatively: (i) from POP-Q: genital hiatus (GH-Level III); (ii) from PR-Q: perineal gap (PG-Level III), posterior vaginal vault descent (PVVD-Level I). The data for introital defects (GH, PG) were separated according to the need for vault fixation using a SSC due to a larger vaginal defect (PVVD over 5 cm). RESULTS: Mean (SD) preoperative GH and PG were both significantly larger in the SSC versus no SSC group: GH (3.73 [0.94] vs 3.36 [0.83] cm, P = 0.01); PG (2.91 [1.0] vs 2.61 [0.91] cm, P = 0.05). SSC performed with the PR (84%); not performed (16%) cases. The mean (SD) postoperative reduction in GH (antero-posterior) was significantly (29%-P = 0.002) greater-1.1 (0.69) cm (29.5%) in the SSC group and 0.77 (0.49) cm (22.9%) in the no SSC group. The decrease in the PG (transverse) was greater by 11% (0.05). CONCLUSIONS: Levels I and III defects are associated with PRs; preoperatively larger vaginal vault (PVVD over 5 cm) and larger introital defects (GH, PG). Postoperatively, vault fixation resulted in significantly greater reduction in the introital defects. SUMMARY: Vaginal vault fixation (SSC) significantly improves the vaginal introital repair.

The vaginal vestibule: assessing the case for an anterior and posterior division.

The vaginal vestibule has not been the subject of a dedicated journal article. Recent terminology has suggested its division into anterior and posterior components. The case for this division has not yet been assessed. Both components extend laterally from the hymen to the junction with the labia minora. The posterior vaginal vestibule is proposed to extend from the posterior aspect of the hymen to the anterior edge of the perineum whilst the anterior vestibule extends from the posterior aspect of the hymen to just below the clitoris. Anatomical considerations (differing layers) might firstly support the above division. The posterior vestibule, by necessity, is far more flexible with the superficial aspect (approximately 1.5 cm), anatomically and histologically, comprising skin and subcutaneous tissue, with perineal musculature deep to this. In turn, it is more likely to be subject to obstetric and surgical considerations than the anterior vaginal vestibule. Obstetric trauma, in particular, would tend to create defects, particularly at its posterior margin. Many dermatological and microbiological considerations may be common to both anterior and posterior vestibule. Any dermatological condition of the vestibule can result in sexual dysfunction and can be complicated by secondary muscular spasm. Congenital anomalies will differ anteriorly and posteriorly. Multiple considerations can be identified to support the case for division of the vaginal vestibule into anterior and posterior components. Neurourol.

An International Urogynecological Association (IUGA)/International Continence Society (ICS) joint report on the terminology for the conservative and nonpharmacological management of female pelvic floor dysfunction.

INTRODUCTION AND HYPOTHESIS: There has been an increasing need for the terminology on the conservative management of female pelvic floor dysfunction to be collated in a clinically based consensus report. METHODS: This Report combines the input of members and elected nominees of the Standardization and Terminology Committees of two International Organizations, the International Urogynecological Association (IUGA) and the International Continence Society (ICS), assisted at intervals by many external referees. An extensive process of nine rounds of internal and external review was developed to exhaustively examine each definition, with decision-making by collective opinion (consensus). Before opening up for comments on the webpages of ICS and IUGA, five experts from physiotherapy, neurology, urology, urogynecology, and nursing were invited to comment on the paper. RESULTS: A Terminology Report on the conservative management of female pelvic floor dysfunction, encompassing over 200 separate definitions, has been developed. It is clinically based, with the most common symptoms, signs, assessments, diagnoses, and treatments defined. Clarity and ease of use have been key aims to make it interpretable by practitioners and trainees in all the different specialty groups involved in female pelvic floor dysfunction. Ongoing review is not only anticipated, but will be required to keep the document updated and as widely acceptable as possible. CONCLUSION: A consensus-based terminology report for the conservative management of female pelvic floor dysfunction has been produced, aimed at being a significant aid to clinical practice and a stimulus for research.

Posterior vaginal compartment repairs: Where are the main anatomical defects?

INTRODUCTION AND HYPOTHESIS: Traditionally, it has been believed that posterior vaginal compartment prolapse was largely due to defects in the rectovaginal fascia, with surgical repairs concentrating on addressing this defect. We aimed to determine the relative size of defects at the different vaginal levels (I-III) following a large number of posterior vaginal compartment repairs (PRs) to determine whether this traditional viewpoint is still appropriate. METHODS: In a cross-sectional study of 300 consecutive PRs, mostly following prior or concomitant hysterectomy, two sets of markers of posterior compartment prolapse were used to measure anatomical defects at levels I-III: (i) from Pelvic Organ Prolapse Quantification (POP-Q) system points C, Ap, Bp, and genital hiatus (GH), and from Posterior Repair Quantification (PR-Q) perineal gap (PG), posterior vaginal-vault descent (PVVD), midvaginal laxity (MVL)-vault undisplaced, and rectovaginal fascial laxity (RVFL). RESULTS: The largest defects were found at level I (PVVD: mean 6.0 cm; point C, mean minus 0.9 cm), and level III (PG, mean 2.9 cm; GH, mean 3.7 cm). Level II defects (MVL-vault undisplaced, mean 1.3 cm; RVFL, mean 1.1 cm; points Ap, Bp, both mean 1.0 cm) were relatively small. CONCLUSIONS: This study suggests that the defects found at surgery for posterior vaginal compartment prolapse were more frequent at the vaginal vault (level I) and vaginal introitus (level III) than at midvagina (level II). These findings should have implications for surgical planning.

Perineorrhaphy quantitative assessment (Pe-QA).

INTRODUCTION AND HYPOTHESIS: Perineorrhaphy (Pe) has not been subject to a comprehensive perioperative quantitative assessment (QA). We wish to nominate such an assessment (Pe-QA) for any Pe, through testing the QA on the excision of the perineal gap (PG) at the time of posterior repair (PR). METHODS: At 50 consecutive PRs, the following measurements were taken pre- and postoperatively: (i) perineorrhaphy width (PW) equals PG [1]; (ii) perineorrhaphy depth (PD); (iii) perineal length (PL); (iv) midperineal thickness (MPT); (v) genital hiatus (GH) and (vi) total posterior vaginal length (TPVL). The total vaginal length was also measured. Surgical details deemed appropriate to each repair were recorded. RESULTS: The overall means and ranges (cm) were: (i) PW 2.9 (1.5-5.5); (ii) PD 1.6 (0.8-2.0); (iii) PL 2.9 (1.5-4.5); (iv) MPT 0.7 (0.4-1.1); (v) GH 3.9 (2.3-6.5); (vi) TPVL 9.2 (6.0-12.5). Excision of PG (100 % cases reducing PW and PD to zero) resulted in a mean 23.6 % increase in total vaginal length over that if the repair was commenced at the hymen, despite a 3.3 % decrease in the TPVL perioperatively. There was a mean 30.8 % reduction in the GH, a mean 27.6 % increase in the PL and a mean 57.1 % increase in the MPT. CONCLUSIONS: Pe and the anatomical results of such surgery can be subject to quantitative assessment allowing comparison studies between different forms of Pe and possibly other types of perineal surgeries.

Posterior repair quantification (PR-Q) using key anatomical indicators (KAI): preliminary report.

INTRODUCTION AND HYPOTHESIS: Posterior vaginal compartment repairs (PR) have traditionally involved a subjective approach. We aim to quantify such repairs using key anatomical indicators (KAI). METHODS: At 50 consecutive PRs: perineal gap (PG); posterior vaginal vault descent (PVVD); mid-vaginal laxity (MVL-vault undisplaced/displaced); and recto-vaginal fascial laxity (RVFL) were measured. The total posterior vaginal length (TPVL) and from POP-Q, TVL, GH, Ap, Bp C, D were also measured. Surgical details deemed appropriate to each repair were recorded. RESULTS: A mean preoperative PG of 2.5 cm was reduced to 0.0 cm postoperatively by excision (100 % cases) with an average increase of 21.6 % in total vaginal length over that if the repair was commenced at the hymen. There was an average reduction of 25.0 % in the genital hiatus (GH). Mean PVVD was 5.3 cm overall; 6.4 cm for 31 out of 50 (62 %) undergoing sacrospinous colpopexy; 3.5 cm for 19 out of 50 (38 %) with no ligamentous vault fixation. An approximate "cut-off" for PVVD of 5 cm may assist with the differentiation of cases where vault fixation may be desirable. Up to 52 % (1.4/2.7 cm) of preoperative MVL displacement was due to vaginal vault descent. The MVL undisplaced (mean 1.3 cm) may better guide vaginal mucosal trimming. RVFL averaged just 0.8 cm with 22 out of 50 (44 %) RVFL being 0.5 cm or less, and not requiring any RVF plicatory sutures. CONCLUSIONS: It is possible to use KAI to assist the planning and execution of posterior vaginal compartment surgery. The PG, PVVD, MVL, and RVFL can indicate surgical measures in the perineum, vaginal vault, vaginal mucosa, and recto-vaginal space respectively.
