Effectiveness and safety of a novel, collapsible pessary for management of pelvic organ prolapse.

BACKGROUND: Pessaries are an effective treatment for pelvic organ prolapse, yet currently available pessaries can cause discomfort during removal and insertion. An early feasibility trial of an investigational, collapsible pessary previously demonstrated mechanical feasibility during a brief 15-minute office trial. Longer-term, patient-centered safety and efficacy data are needed. OBJECTIVE: This study aimed to assess the effectiveness and safety of the investigational vaginal pessary for pelvic organ prolapse at 3 months. STUDY DESIGN: This was a prospective, 7-center, open-label equivalence study with participants serving as their own controls. Subjects were current users of a Gellhorn or ring pessary with ≥stage 2 prolapse. Subjective and objective data were collected at baseline for 1 month while subjects used their current pessary. Data were then collected throughout a 3-month treatment phase with the study pessary. The primary outcome was change in Pelvic Floor Distress Inventory-20 score. Secondary outcome measures included objective assessment of prolapse support, changes in the Pelvic Floor Impact Questionnaire-7, and pain with insertion and removal, measured using a visual analog scale. Data from subjects fitted with the study pessary were analyzed using an intention-to-treat approach, and those who dropped out were assigned scores at the upper limit of the predefined equivalence limits. Secondary per protocol analyses included subjects who completed treatment. The study was powered to 80% with a minimal important change equivalence limit of 18.3 points on the Pelvic Floor Distress Inventory-20 scale. Square root transformations were used for nonparametric data, and P values were adjusted for multiple comparisons. RESULTS: A total of 78 subjects were enrolled, however, 16 withdrew before study pessary placement. The study pessary was fitted in 62 subjects (50 ring and 12 Gellhorn pessary users), and 48 (62%) completed the 3-month intervention. The change in Pelvic Floor Distress Inventory-20 scores at 3 months demonstrated equivalence when compared with the subjects' baseline scores (mean difference, -3.96 [improvement]; 90% confidence interval, -11.99 to 4.08; P=.002). Among those completing study, the Pelvic Floor Distress Inventory-20 scores, equivalence was not demonstrated and scores favored the study pessary (mean difference, -10.45; 90% confidence interval, -20.35 to 0.54; P=.095). Secondary outcomes included objective measures of support, which were similar (mean difference: Ba, 0.54 cm; Bp, 0.04 cm, favoring study pessary; improvement in mean Pelvic Floor Impact Questionnaire-7 scores for those who completed the trial: before, 32.23; after, 16.86; P=.019), and pain with insertion and removal, which was lower with the study pessary than with the subject's own pessary (mean difference visual analog scale score insertion, 9.91 mm; P=.019; removal, 11.23 mm; P=.019). No serious adverse events related to the pessary were reported. CONCLUSION: Equivalence was demonstrated in the primary outcome of the study pessary when compared with current, noncollapsible pessaries in terms of change in severity and bother of pelvic floor symptoms. Among participants who completed the trial, the Pelvic Floor Impact Questionnaire-7 improved with study pessary use and change in Pelvic Floor Distress Inventory-20 scores were nonequivalent, favoring the study pessary. Subjects reported significantly lower pain scores with both pessary insertion and removal with the novel collapsible pessary when compared with their standard pessary.

The use of midurethral sling in the correction of low-stage cystoceles: a prospective randomized trial.

INTRODUCTION AND HYPOTHESIS: The objective was to assess whether midurethral slings (MUS) can improve both stress urinary incontinence (SUI) and cystoceles. MUS with anterior colporrhaphy (AC) as a treatment for SUI with cystocele is more invasive and carries greater risk than MUS alone. METHODS: This is a prospective randomized study involving women with stage 1 or 2 cystocele and SUI, who were > 21 years of age, who had had no previous surgery for SUI. Predominant SUI, symptomatic anterior pelvic organ prolapse, and informed consent were mandatory. Patients were randomized as to whether AC had been performed. The sling procedure was left to the surgeon's discretion: pubovaginal sling, tension-free vaginal tape, or trans-obturator tape. Success was defined as a negative stress test and no evidence of cystocele upon local examination. RESULTS: Ninety-eight patients were enrolled, 48 underwent MUS, and 50 underwent MUS and AC. Mean age ± SD was 44.96 ± 8.13 years. Baseline characteristics were similar. Operative time and blood loss were significantly higher in the MUS/AC group (p = 0.01 and 0.02 respectively). At 3 months, success was 79.1% and 77.8% in the MUS and MUS/AC groups respectively. This was maintained until 6 months (79.1% and 77.8% respectively). At 1 year, the results were comparable with success rates of 96.2% and 87.0% in the MUS and MUS and AC groups respectively. Symptom scores were comparable at 6- and 12-month evaluations. CONCLUSION: Midurethral slings correct symptomatic stage 1 or 2 cystoceles without the need for AC, which carries the risk of a significantly longer procedure and more significant blood loss.

Does vaginal surgery for correction of pelvic organ prolapse improve urinary function? A prospective cohort study.

INTRODUCTION AND HYPOTHESIS: Pelvic organ prolapse (POP) is caused by an imbalance in the stability of the pelvic organs, resulting in loss of support. The most common types of POP, anterior and apical, are associated with lower urinary tract symptoms (LUTS) such as bladder outlet obstruction and detrusor overactivity (DO). Vaginal surgery may improve LUTS and overall urinary symptoms. We assessed urodynamic (UD) parameters and urinary symptoms before and after vaginal surgery for POP correction. METHODS: A prospective cohort of 59 women with symptomatic anterior and/or apical POP associated with urinary symptoms and with indications for vaginal surgery were included. POP surgeries included anterior colporrhaphy and vaginal hysterectomy with culdoplasty (VH) and with/without concomitant posterior colporrhaphy and mid-urethral sling (MUS). All participants underwent UD evaluation and answered urinary symptom questionnaires pre- and 3 months post-surgery. RESULTS: Anterior colporrhaphy was performed in all patients: 45.7% with associated VH and 54.2% with concomitant MUS. Preoperative ICIQ-OAB score >8 points was significantly associated with DO (p<0.02) and decreased after surgery (9±4.3 to 3.2±3.0, p<0.001). All other questionnaires demonstrated improvements in urinary symptoms. Stress urinary incontinence rate decreased from 59.6% to 21% (p<0.001). Post-void residual (PVR) volume and Valsalva maneuver also decreased (p<0.001). CONCLUSIONS: Pelvic organ prolapse surgery reduced the prevalence of urgency symptoms, and all questionnaires on urinary symptoms showed clinically significant improvement. Vaginal surgery for POP, even combined with MUS, significantly reduced PVR volume and improved urgency symptoms.

Pubococcygeal Line Versus H-line as MR Defecography Reference for Bladder Descent.

INTRODUCTION AND HYPOTHESIS: Magnetic resonance defecography imaging techniques have been used widely to study pelvic floor function and diagnose pelvic organ prolapse (POP). The aim of this study was to investigate the diagnostic accuracy of the H-line to detect bladder descent compared with the current landmark, the pubococcygeal line (PCL). METHODS: In this retrospective cohort study, patients who underwent MR defecography in our medical center and were diagnosed with moderate to severe cystocele by radiological measurements were recruited. One rest image and one maximum evacuation image for each subject were used for the following measurements: bladder base perpendicular distance from the genital hiatus (GH), indicative of clinically significant bladder descent, PCL as the current radiological reference line, and the H-line, or minimal levator hiatus line, indicative of pelvic floor muscle and connective tissue support. Subjects were categorized as having clinically significant cystocele if the "bladder base" reached within 1 cm or lower of the GH (stage II or higher cystocele). A comparison was performed to assess differences and predictive capabilities of the reference lines relative to the GH measure. RESULTS: Seventy subjects were included, 30 with clinically significant bladder descent based on distance to GH. Women with bladder descent were older (64.0 ± 11.8 vs 51.2 ± 15.6, p < 0.001), had increased parity (3 [1-7] vs 2 [0-5], p = 0.009), and had a bladder that descended lower than the H-line at rest (1.9 ± 0.5 vs 2.2 ± 0.4, p = 0.003) and evacuation (-2.4 ± 1.6 vs -0.7 ± 1.1, p < 0.001). Multivariate regression analysis confirmed that age, length of the H-line at evacuation, the perpendicular distances between the H-line and the lowest bladder point at rest, and the PCL to the lowest bladder point at evacuation significantly correlated with bladder descent. Receiver operating characteristic analysis was used to identify a measurement threshold to diagnose clinically significant cystocele for both measurements, bladder base to the H-line: -1.2 (80.0, 72.5) area under the curve (AUC) 0.82, and bladder base PCL: -3.3 (77.8, 79.5) AUC 0.86. CONCLUSION: Our data support the application of using the minimal levator hiatus plane and specifically the H-line as a reliable landmark to diagnose bladder descent using MR defecography imaging.

A novel suturing technique for natural tissue repair in cystocele treatment.

BACKGROUND: Recently, natural tissue repair has become popular in the treatment of pelvic organ prolapsed. In this study, we compared patients who underwent cystocele repair with the rug-weaving plication technique, a natural tissue repair method implemented since 2022 for anterior prolapse, with those treated using conventional colporrhaphy. METHODS: We retrospectively reviewed the data of 65 patients who underwent anterior vaginal wall repair with the rug-weaving plication technique (n = 33, Group 1) or conventional colporrhaphy (n = 32, Group 2). We recorded the patients' clinicodemographic and surgical data. At the 6-month postoperative follow-up, we assessed patients' complaints, degree of prolapse (using the simplified Pelvic Organ Prolapse Quantification system), and pelvic floor muscle strength (using the Modified Oxford Score). Anterior vaginal wall thickness was measured using transvaginal ultrasonography. We compared clinicodemographic and surgical data and postoperative outcomes between the two groups. RESULTS: The two groups were comparable in terms of age (p = 0.326), number of pregnancies (p = 0.307), number of parities (p = 0.555), preoperative anterior wall simplified Pelvic Organ Prolapse Quantification grade (p = 0.380), preoperative apical prolapse simplified Pelvic Organ Prolapse Quantification grade (p = 0.518), postoperative Modified Oxford Score (p = 0.857), operation time (p = 0.809), postoperative haemoglobin (p = 0.674), and amount of bleeding (p = 0.951). Compared with Group 2, Group 1 had significantly higher postoperative anterior vaginal wall thickness (p < 0.001) and significantly lower postoperative anterior wall simplified Pelvic Organ Prolapse Quantification grade (p < 0.001). CONCLUSIONS: The rug-weaving plication technique may offer a viable alternative for cystocele repair without mesh, using natural tissue and potentially reducing mesh-related complications and recurrence rates. CLINICAL TRIAL NUMBER: NCT06410469 (03/05/2024).

Unilateral levator avulsion increases the risk of de novo stress urinary incontinence after cystocele repair.

INTRODUCTION: Patients without concurrent baseline stress urinary incontinence (SUI) can develop de novo SUI after transvaginal mesh surgery (TVM) for cystocele repair. Surgeons should be aware of de novo SUI risk factors after TVM. METHODS: A total of 1124 women who were underwent TVM surgeries were recruited and assessed for eligibility from January 1, 2012 to April 30, 2021. All data related to patients and surgeries was collected, which included general conditions, clinical examination, surgery records, and follow-up results. Patients were divided into three groups according to follow-up results and data were compared with each group. The relative risk (RR) of de novo SUI with levator avulsion was also calculated. RESULTS: Three hundred thirty-six patients were included in this study. They were divided into no complication group (n = 249), de novo SUI group (n = 68), and other complications group (n = 19). It seemed elder or obese women had a higher risk of de novo SUI after TVM (p < 0.05). In de novo SUI group, incidence of levator avulsion before surgery were higher than the other two groups (p = 0.001). TVM can significantly change a prolapse to point Aa and Ba on POP-Q quantification system (p < 0.05). RR ratios of de novo SUI with unilateral avulsion group is 2.60 (95% confidence interval [CI] 1.39-4.87), and 2.58 (95%CI 0.82-8.15) for bilateral group. CONCLUSION: Unilateral levator avulsion, instead of bilateral levator avulsion, is a risk factor of de novo SUI after cystocele repair surgery.

The prevalence of overt, occult, and no-demonstrated stress urinary incontinence and their clinical and urodynamic findings in women with advanced-stage cystoceles.

OBJECTIVES: To elucidate the prevalence of overt, occult and no demonstrated (ND) stress urinary incontinence (SUI) in women with advanced-stage cystoceles. STUDY DESIGN: Between November 2011 and January 2017, all women with ≥stage 2 cystoceles were retrospectively enrolled. Overt SUI was diagnosed before the prolapse reduction test, and occult SUI was diagnosed when urine leakage was noted after a reduction test with vaginal gauze. Otherwise, a diagnosis of ND-SUI was made. MAIN OUTCOME MEASURES: The prevalence, clinical and urodynamic findings of overt SUI, occult SUI, and ND-SUI. RESULTS: In 480 enrolled women, 62% had overt SUI, 17% had occult SUI, and 21% had ND-SUI. The occult SUI group had the most advanced prolapse. The pad weight results after prolapse reduction (37.3 ± 44.3 vs. 13.4 ± 21.9, p < 0.05), the bladder capacity (243 ± 54 vs. 273 ± 48, p < 0.001), and questionnaires regarding life quality were significantly different between the overt SUI and the occult SUI groups. Bladder oversensitivity (BO) was the most common urodynamic diagnosis (389/480, 81%), especially in overt SUI, while urodynamic stress incontinence (56/480, 12%) and detrusor overactivity (60/480, 13%) were uncommon. The cutoff value of stage 3 uterine prolapse was the strongest predictor for predicting occult SUI (sensitivity = 30.3%, specificity = 78.5%; area = 0.60, 95% CI: 0.52-0.68). CONCLUSIONS: SUI occurs in a ratio of 3:1:1 among cases with overt, occult, and no demonstrable symptoms. BO is the most common urodynamic diagnosis. Pad test with prolapse reduction remains an important tool, especially for coexistent stage 3 uterine prolapse.

Risk factors for postoperative pain after cystocele repair with mesh.

INTRODUCTION AND HYPOTHESIS: Prolapse is a common condition seen in women and its therapeutical management consists first and foremost of surgery. Postoperative pain is one of the most common side effects seen after surgery. The objective of this study was to identify risk factors for postoperative pain after cystocele repair with mesh. METHODS: This is a secondary analysis of the multicenter randomized trial PROSPERE, which compared cystocele repair with mesh according to the vaginal or laparoscopic approach. The presence of postoperative pain was assessed by a pain-specific self-reported questionnaire (Questionnaire de Baudelocque). The statistical analysis is based on the Wilcoxon, Chi-squared, and Fisher's tests. RESULTS: The prevalence of postoperative pain (pain persisting more than 6 months) was 39% (80 out of 205, 95% CI 32.4-46.1), with 6.3% (13 out of 205) of chronic pain reports. Preoperative pain was the only statistically significant risk factor OR = 2.32 (p = 0,007; 95% CI 1.24-4.36). CONCLUSIONS: Surgeons must be careful with preoperative painful prolapse and should inform their patient of the risk of developing postoperative chronic pain.

Effect of anterior repair on sexual function in heterosexual couples.

INTRODUCTION AND HYPOTHESIS: Little is known about the impact of native tissue repair techniques on heterosexual intercourse. This study was aimed at investigating the effect of anterior colporrhaphy on women's and their partners' sexual function. METHODS: Sexually active women with a male partner who were diagnosed with anterior wall prolapse without any incontinence were prospectively recruited from a single academic center. Demographic data were collected and a Pelvic Organ Prolapse Quantification examination was performed. Before and 3 months post-operatively, women completed two validated questionnaires to assess sexual function, the International Consultation on Incontinence Questionnaire Vaginal Symptoms short form (ICIQ-VS SF) 55, and the Female Sexual Function Index (FSFI), and their male partners completed the International Index of Erectile function-5. Pre- and post-operative results were compared using a paired t test. RESULTS: This study was conducted in the gynecology department of a university hospital between May 2022 and June 2023, where 50 heterosexual couples were enrolled and underwent isolated anterior repair. The mean age of women and their partners were 44.3 ± 5.12 and 48.1 ± 5.81 respectively. Overall, female sexual function improved significantly from pre- to 3 months postoperatively with a decrease in ICIQ-VS SF scores from 13.3 ± 3.27 to 1.7 ± 1.1 (p < 0.05) and an increase in FSFI scores from 21.74 ± 9.37 to 29.28 ± 9.97 (p < 0.05). The only domain that did not improve was sexual pain. For their male partners, there was a similar significant improvement in sexual function with an increase in scores from 48.71 ± 8.71 to 60.68 ± 8.63 (p < 0.05). CONCLUSIONS: Isolated anterior repair was associated with improved short-term sexual function amongst heterosexual couples.

Double-layered anterior colporrhaphy (DAC)-video and mid-term follow-up of 60 patients.

INTRODUCTION AND HYPOTHESIS: Anterior colporrhaphy (AC) exhibits high recurrence rates, and this issue is not appropriately addressed by alloplastic material, which often necessitates reoperation. Aiming to improve the anatomical cure rate, we implemented double-layered anterior colporrhaphy (DAC). With a retrospective investigation, precise description and video of the surgical technique, we want to contribute to the development of native tissue anterior repair. METHODS: Women treated by DAC and vaginal hysterectomy were included. Primary outcome was anatomic cure defined as prolapse < stage 2. Secondary outcomes were complication rate, resolution of postvoid residual urine, reoperation for prolapse and patient satisfaction. Follow-up encompassed a clinical gynecologic examination, the German Pelvic Floor Questionnaire and a response scale for postoperative quality of life (QoL). The key difference between DAC and AC is the continuous suture followed by the traditional interrupted sutures. RESULTS: One hundred one patients were eligible, and 60 patients attended follow-up. Cure was achieved in 49 cases (81.7%) of cystocele with a median follow-up of 19.3 months. Fifty-five patients (91.7%) indicated an improvement in QoL. CONCLUSIONS: We observed high anatomic cure rate and satisfaction after DAC. With description and video of the technique, it is reproducible and comparable to other methods. Randomized controlled trials should follow.

Urodynamic profile of voiding in patients with pelvic organ prolapse after surgery: a systematic review with meta-analysis.

INTRODUCTION AND HYPOTHESIS: Pelvic organ prolapse (POP) is a defect of the female pelvic floor. Stress urinary incontinence (SUI), urge urinary incontinence (UUI), and obstructive symptoms may occur in these patients. The objective of surgical treatment is to restore the anatomy and function of the pelvic floor; however, it may prompt urinary symptoms not present previously. We performed a systematic review and meta-analysis to determine urodynamic changes in patients undergoing surgical correction for POP. METHODS: PubMed and Cochrane databases were searched for studies that contained data from urodynamic evaluation before and after vaginal surgery for POP. The main urodynamic data collected were free uroflowmetry (maximum flow [Qmax], voided volume, and post-void residual volume [PVR]), cystometry (bladder capacity, presence of detrusor overactivity [DO], SUI or UUI, and Valsalva leak point pressure), and pressure × flow study (detrusor pressure at maximum flow [PdetQmax], Qmax, and PVR). RESULTS: A total of 22 studies were included (1,549 women). Patients had a significantly higher prevalence of DO before surgery (OR = 1.56; 95% CI = 1.06-2.29), and surgeries without sling placement demonstrated a tendency to ameliorate DO. Patients who did not receive a sling were more incontinent after surgery. Bladder-emptying parameters improved after surgery, with higher PdetQmax before surgery (IV = 3.23; 95% CI = 0.45-1.18). Patients who did not receive MUS presented a lower Qmax (IV = -3.19; 95%CI = -4.09 to -2.30) and a higher PVR (IV = 27.89; 95%CI = 15.68-40.1) before surgery. CONCLUSION: Correction surgery for POP yields better urodynamic emptying parameters, with a reduction in the prevalence of DO. In contrast, sling placement enhances obstructive parameters.

Variations in structural support site failure patterns by prolapse size on stress 3D MRI.

INTRODUCTION AND HYPOTHESIS: Our objective was to develop a standardized measurement system to evaluate structural support site failures among women with anterior vaginal wall-predominant prolapse according to increasing prolapse size using stress three-dimensional (3D) magnetic resonance imaging (MRI). METHODS: Ninety-one women with anterior vaginal wall-predominant prolapse and uterus in situ who had undergone research stress 3D MRI were included for analysis. The vaginal wall length and width, apex and paravaginal locations, urogenital hiatus diameter, and prolapse size were measured at maximal Valsalva on MRI. Subject measurements were compared to established measurements in 30 normal controls without prolapse using a standardized z-score measurement system. A z-score greater than 1.28, or the 90th percentile in controls, was considered abnormal. The frequency and severity of structural support site failure was analyzed based on tertiles of prolapse size. RESULTS: Substantial variability in support site failure pattern and severity was identified, even between women with the same stage and similar size prolapse. Overall, the most common failed support sites were straining hiatal diameter (91%) and paravaginal location (92%), followed by apical location (82%). Impairment severity z-score was highest for hiatal diameter (3.56) and lowest for vaginal width (1.40). An increase in impairment severity z-score was observed with increasing prolapse size among all support sites across all three prolapse size tertiles (p < 0.01 for all). CONCLUSIONS: We identified substantial variation in support site failure patterns among women with different degrees of anterior vaginal wall prolapse using a novel standardized framework that quantifies the number, severity, and location of structural support site failures.

Analysis of the anatomical and biomechanical characteristics of the pelvic floor in cystocele.

INTRODUCTION: Stress urinary incontinence (SUI) occurs due to disruption of the pelvic floor anatomy; however, the complexity of the pelvic floor support structures and individual patient differences make it difficult to identify the weak points in the pelvic floor support that cause SUI to occur, develop, and recur. This study aimed to analyze the pelvic floor anatomy, structural features, and biomechanics of cystoceles to develop more effective treatment plans with individualized and precise healthcare. MATERIAL AND METHODS: In this observational case-controlled study (clinical trial identifier BOJI201855L), 102 women with normal pelvic floor function and 273 patients diagnosed with cystocele degrees I-III were identified at Shanghai General Hospital from October 2016 to December 2019. We combined ultrasound and vaginal tactile imaging (VTI) to assess the anatomy and biomechanical functions of the anterior and posterior vaginal walls. Both examinations included relaxation and muscle tension tests. RESULTS: Of the 42 VTI parameters, 13 were associated with the degree of cystocele, six with an increase in the urethral rotation angle (pointing to the mobility of the urethra), and six with a decrease in the retrovesical angle (pointing to hypsokinesis and decrease in bladder position). According to these data, the strength of tissues, especially the muscles in both the anterior and posterior compartments, contributes to the stability of the pelvic floor structure. The strength of the levator ani muscle (LAM) is important for the degree of cystocele, mobility of the urethra, hypsokinesis, and decrease in bladder position. CONCLUSIONS: In general, the biomechanical status of the pelvic floor in patients with cystocele is complex and involves various muscles, ligaments, tendons, and fascia. Of these, repair and exercise of the LAM have not received much attention in the treatment of patients with cystoceles, which may be an important risk factor for the high recurrence rate.

Does Cystocele Type Vary Between Vaginally Parous and Nulliparous Women?

OBJECTIVES: To evaluate whether cystocele type varies with vaginal parity. METHODS: Retrospective analysis of 464 vaginally nulliparous women seen at 2 urogynecology units between November 2006 and November 2019. A control group consisted of 871 vaginally parous women seen between July 2017 and November 2019. Patients underwent a standardized interview, POPQ, urodynamic testing, and translabial ultrasound. On imaging, significant cystocele was defined as bladder descent to ≥10 mm below symphysis pubis. Volume datasets were analyzed offline and blinded against clinical data. RESULTS: Of 5266 women seen during the inclusion period, 464 were vaginally nulliparous. Three were excluded due to missing data, leaving 461. A control group of 871 parous women was generated from patients seen during the last 2.5 years of the inclusion period. Vaginally nulliparous women were presented at a younger age compared to vaginally parous women (P < .001). Symptoms of prolapse were reported in 104 (22%) nulliparae and 489 (56%) parous women (P < .0001). Vaginally parous women demonstrated more bladder descent (P < .0001) and more cystocele (418/871 versus 43/461, P < .0001), with a higher proportion of type III cystocele (cystocele with intact retrovesical angle) (20/43 versus 273/ 418, P < .0001). Cystourethrocele (Green type II) was more common in nulliparae and cystocele type III in parous women (P = .015). On multivariate analysis, these differences in proportions remained significant (P = .049). CONCLUSIONS: Nulliparity was associated with a higher proportion of Green type II cystoceles. Green type III cystocele was more common in vaginally parous women, suggesting that the latter may be more likely to be due to childbirth-related pelvic floor trauma.

Chaotic lipoma with proximal syrinx -a (not so) rare variant - review of the literature, possible embryology and management.

Chaotic lipomas are an extremely rare variant of spinal lipomas. This entity was first defined in 2009 by Pang and colleagues. Not much has been written about this variant. Its characteristic is the haphazard distribution of DREZ (Dorsal root entry zone), nerve roots and placode-lipoma interface. Thus complete/near-total excision of this lesion is quite difficult. We describe a case of chaotic spinal lipoma and elucidate the challenges faced in the management of this entity and review the literature. We performed a thorough systematic review with the keyword 'chaotic', 'Lipomyelomeningocele', 'Complex Lipomyelomeningocele', 'LMMC', 'Lumbar lipoma', 'spinal lipoma' in the google scholar and PUBMED data system for indexed literature on the above topic with no particular time frame. The studies quoted range earliest from 1970 till currently. Additional potential relevant articles were further retrieved through a manual search of references from original reports. Out of 42 studies, a total of 21 publications were selected which could have encountered a chaotic variant, but due to the term introduced only recently in 2009, may have been described differently. Studies encompassing true lipomeningomyelocele were excluded from our review. What we found out? Chaotic lipoma may not be a new entity. The scarce description in literature may be in part due to non-introduction and unclear description of this term earlier. The management of this variant is particularly challenging with basic principles remaining the same. Meticulous near-total excision and placode-lipoma construct are the major obstacles.

Transvaginal repair of anterior vaginal wall prolapse with polyvinylidene fluoride (PVDF) mesh: an alternative for previously restricted materials?

INTRODUCTION AND HYPOTHESIS: To study the mid-term safety and functional outcomes of transvaginal anterior vaginal wall prolapse repair using polyvinylidene fluoride (PVDF) mesh (DynaMesh®-PR4) by the double trans-obturator technique (TOT). METHODS: Between 2015 and 2020, we prospectively included women with symptomatic high-stage anterior vaginal wall prolapse with or without uterine prolapse or stress urinary incontinence (SUI) in the study. The patients underwent transvaginal repair of the prolapse using PVDF mesh in two medical centers. We followed all patients for at least 12 months. We recorded the characteristics of vaginal and sexual symptoms, urinary incontinence, and prolapse stage pre- and postoperatively using International Consultation on Incontinence Questionnaire-Vaginal Symptoms (ICIQ-VS), International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI-SF), and Pelvic Organ Prolapse Quantification (POP-Q) system, respectively. RESULTS: One hundred eight women were included in the final analysis with a mean follow-up time of 34.5 ± 18.6 months. The anatomical success was achieved in 103 (95.4%) patients. There was a significant improvement in patients' vaginal symptoms, urinary incontinence, and quality of life scores postoperatively (p < 0.0001). Only six patients (5.5%) had mesh extrusion, five of whom were managed successfully. The total rates of complications and de novo urinary symptoms were 21.3% and 7.4%, respectively. Significant pain was reported in 17 cases (15.7%). CONCLUSION: Our findings show that using PVDF mesh in the double TOT technique for anterior vaginal wall prolapse repair is a safe procedure with high anatomic and functional success rates and acceptable complication rates in mid-term follow-up.

Clinical outcome and urodynamic changes of tailored transvaginal mesh surgery for pelvic organ prolapse: A mid-term 40 Months follow-up.

PURPOSE: To evaluate the changes in clinical outcome and urodynamic parameters after tailored anterior transvaginal mesh (ATVM) surgeries in a mid-term follow-up. METHODS: Between November 2011 and December 2015, women with ≥stage II pelvic organ prolapse (POP) who underwent ATVM surgeries were retrospectively reviewed. The data-reviewing timeframe was until December 2021. Clinical and urodynamic diagnoses regarding urinary symptoms were evaluated before and after the operation. RESULTS: A total of 160 women were included. Stress urinary incontinence decreased significantly after the operation (99% (159/160) vs. 43% (68/160), p < 0.01), as well as the pad weight (20.5 ± 2.7 vs. 9.4 ± 2.0, p < 0.001) and diagnosis of urodynamic stress incontinence (83% (132/160) vs. 51% (82/160), p < 0.01). Overactive bladder syndrome increased significantly after the operation (18% (29/160) vs. 28% (45/160), p = 0.03), even though the objective parameters, such as first and strong desire to void, bladder oversensitivity, and detrusor overactivity, were all improved after the operation. The pad weight was mostly improved significantly within the first postoperative 2 years. Eighteen (11%) women had global recurrent POP, and only one (0.6%) woman had true recurrence of cystocele. Twenty-four (15%) women had mesh extrusion, and two-thirds of them could be managed in an office setting. CONCLUSION: In women with advanced cystocele, the ATVM surgery provides a favorable anatomic reduction outcome with an acceptable mesh extrusion rate. The ATVM provides an anti-incontinence effect, both in subjective symptoms and objective parameters, but this effect might decline after postoperative 2 years.

The role of hydrodissection in native tissue repair of anterior vaginal wall defects.

AIMS: A variety of surgical techniques are available for vaginal prolapse repair, indicating a lack of consensus. A debate regarding the utility of hydrodissection for splitting the surgical plane of the vaginal wall exists. The aim of this study is to evaluate the impact of hydrodissection in anterior colporrhaphy (AC). MATERIALS: Patients undergoing primary AC were randomly assigned to an approach with (study group) versus without (control group) hydrodissection. Five surgeons performed both techniques, and the trimmed vaginal tissue was retrieved for histological analysis. Two pathologists, blinded to the surgical approach, evaluated the presence of a loose connective tissue at the surgical dissection plane (controversially deemed 'fascia', as explained in this article). In addition, we compared the operative time, pain score and haemoglobin levels. After statistical analysis, data were presented using percentile, and statistical significance was tested using the χ2 and Fisher's exact tests. RESULTS: Forty-six patients underwent primary elective AC, with 23 patients in each, the study and control groups. The groups were comparable regarding age (study group 60.33 ± 11.95 years and control group 59.86 ± 12.04, P = 0.90), menopausal status (study group 17 (73.9%) and control group 15 (68.2%), P = 0.67) and other characteristics. We found no difference in sample characteristics between the two groups. Connective tissue was found in only 13.6% (n = 3) of patients after hydrodissection and in 27.3% (n = 6) of patients without hydrodissection (P = 0.46). The hydrodissection group had significantly less bleeding than the control group (ΔHB 0.66 ± 0.66 vs 1.21 ± 0.84, P = 0.05). CONCLUSIONS: After hydrodissection, less bleeding was noted without compromise the surgical planes.

Pelvic organ prolapse in nulliparae.

BACKGROUND: Pregnancy and childbirth are thought to be the strongest environmental risk factors for pelvic organ prolapse, but prolapse does occur in nulliparae. AIM: To characterise prolapse in vaginal nulliparae. MATERIAL AND METHODS: This was a retrospective study using archived clinical and imaging data of 368 vaginally nulliparous women seen between 2006 and 2017 at two tertiary urogynaecological centres. Patients underwent a standardised interview, clinical examination and 3D/4D translabial ultrasound. Volume datasets were analysed by the second author, blinded against all clinical data, using post-processing software on a personal computer. Significant prolapse was defined as Pelvic Organ Prolapse Quantification system stage ≥2 for the anterior and posterior compartment, and stage ≥1 for the central compartment. On imaging, significant prolapse was defined as previously described. RESULTS: Of 4297 women seen during the inclusion period, 409 were vaginally nulliparous, for whom 368 volume data sets could be retrieved. Mean age was 50 years (17-89) and mean body mass index 29 (16-64). Eighty-one (22%) presented with prolapse symptoms. On clinical examination, 106 women (29%) had significant prolapse, mostly of the posterior compartment (n = 70, 19%). On imaging 64 women showed evidence of significant prolapse (17%), again mostly posterior (n = 47, 13%). Rectovaginal septal defects were even more common in 69 (19%). On multivariate analysis we found no differences between true nulliparae (n = 184) and women delivered exclusively by caesarean section (n = 184). CONCLUSIONS: Prolapse occurs in vaginal nulliparae, but it has distinct characteristics. Rectocele predominates, while cystocele and uterine prolapse are uncommon. Pregnancy and caesarean delivery seem to have little effect.

Profile of women with pelvic organ prolapse at the University Hospital of the West Indies risk factors and presentation.

POP affected 40% of participants in the WHI trial. Risk factors include parity, vaginal delivery, large babies, advancing age, obesity, hysterectomy and lifting. Data suggest African-American women have a lower prevalence of symptomatic POP than other racial groups. Literature review did not show a study of risk factors and symptoms in a black population. Cross-sectional study of women with POP attending urogynaecology clinic at the UHWI from May to October 2013, using an interviewer administered questionnaire was performed and analysed using SPSS version 19 program (SPSS Inc., Chicago, IL). One hundred and eight participants were included: 94.7% postmenopausal (mean 65.08 years) and 94.5% parous (mean 4). Risk factors included obesity (mean BMI 28.82 kg/m2), hysterectomy (28.7%), heavy lifting (51.9%) and chronic cough (13.9%). Symptoms included stress incontinence (40.7%), stranguria (16.7%), faecal incontinence (13.9%), constipation (31.5%), coital urinary and faecal incontinence (6.3%, 12.6%). We concluded risk factors for POP in this population correlates with other studies. Stress urinary incontinence and constipation most frequently reported symptoms in this population.Impact StatementWhat is already known on this subject? Pelvic organ prolapse (POP) is a common condition with multifactorial aetiology. As seen in systematic reviews (Vergeldt TFM, Weemhoff M, IntHout J, Kluivers KB. 2015. Risk factors for pelvic organ prolapse and its recurrence: a systematic review. International Urogynecology Journal 26(11):1559-1573). Study shows white women appeared to have more overall symptoms both from prolapse, as well as urinary symptoms, as compared with black women (Ford AT, Eto CU, Smith M, Northington GM. 2019. Racial differences in pelvic organ prolapse symptoms among women undergoing pelvic reconstructive surgery for prolapse. Female Pelvic Medicine & Reconstructive Surgery 25:130-133).What do the results of this study add? The result highlights the fact that Black women are exposed to similar risk factors and have similar symptoms to other racial groups for POP.What are the implications of these findings for clinical practice and/or further research? These findings can be used to educate women with risk factors about the possibility of developing symptomatic POP. Further research is needed to ascertain the prevalence of POP and to assess knowledge and attitude in this population as we hypothesise that there is generalised assumption in that being black is protective from POP.
