Correction Of Pelvic Organ Prolapse Research Articles

Comparative analysis of methods of surgical correction of post-hysterectomy pelvic organ prolapse.

Aim: a comparative analysis of the results of laparoscopic sacrocolpopexy, sacro-spinous fixation and the developed new method of surgical correction of pelvic organ prolapse after hysterectomy. Materials and methods: The prospective non-randomized study included 57 patients with symptomatic post-hysterectomy prolapse of the pelvic organs of stage II, III, IV, who applied to the Сlinical Hospital «RZD-Medicine» Tula in the period from August 2019 to September 2023 The main group (n=18) consisted of women who underwent surgical correction of post -hysterectomy pelvic organ prolapse in a newly developed way; the second group (n=19) consisted of women who underwent laparoscopic promontofixation according to the classical technique; patients of the third group (n=20) underwent installation of an apical sling using a UroSling-1 mesh endoprosthesis (Lintex LLC, St. Petersburg). The quality of life of the patients was assessed using specialized validated questionnaires: Pelvic Floor Distress Inventory (PFDI-20), Pelvic Floor Impact Questionnaire (PFIQ-7). Patients were asked to fill out questionnaires before surgery, as well as 12 and 24 months after surgical correction of PGP. The patients were invited for a follow-up examination after 1, 6, 12 and 24 months. Results: The duration of the operation in the 2nd group significantly exceeds the indicators of the 1 and 3 groups. The average length of hospital stay in patients of the 1st group was 4,4 ± 0.6 (95% CI 4,1 – 4,7) bed days, the 2nd – 4,9 ± 1,1 (95% CI 4,6 – 5,3), the 3rd – 4,6 ± 0,6 (95% CI 4,3 – 4,9), differences were statistically insignificant (p1-2 = 0,437, p1-3 = 0,137, p2-3 = 0,235). Anatomical results after 24 months at points Aa and Ba showed statistically significant differences. At point Aa, p1-3=0,007, p2-3=0,004, at point Ba, p1-3=0,032, p2-3=0,041. A comparative assessment of the questionnaire data before surgery 12 and 24 months after surgery showed a significant improvement in the quality of life of patients in three groups. Conclusion: The proposed method of correction of post-hysterectomy pelvic organ prolapse provides high anatomical and functional results, and also reduces the likelihood of repeated surgical intervention for recurrence.

Comparative analysis of the efficacy and complications of mid-urethral slings when inserted either in isolation or in conjunction with pelvic organ prolapse surgery.

Stress urinary incontinence (SUI) is a highly prevalent condition that affects between 20 and 50% of the female population. Pelvic organ prolapse (POP) can coexist with SUI and both can be addressed through a vaginal approach. However, it is unclear whether simultaneous surgery for these two conditions can influence the outcome of incontinence treatment. To evaluate the objective and subjective effectiveness of the transobturator suburethral (TO) band by comparing two groups: group A, of patients undergoing surgery for stress urinary incontinence (SUI) by insertion of TO mesh, and group B, formed for patients requiring simultaneous correction of pelvic organ prolapse (POP) in addition to TO mesh insertion. This is an observational, descriptive and retrospective study in which 91 patients participated: 33 (group A) underwent surgery for SUI and 58 (group B) underwent corrective surgery for pelvic organ prolapse (POP) and TO band simultaneously. Variables included: total urinary continence, objective urinary continence, subjective urinary continence (satisfaction levels and two validated questionnaires (PGI-1 and ICIQ-SF)) and complications. Regarding total continence, from the seventh to the ninth year, statistically significant differences were observed, with total continence being higher in group A. Objective continence decreased in both groups during the follow-up period. No significant differences were found between the two groups regarding subjective urinary continence (ICIQ-SF) and the degree of improvement after surgical treatment (PGI-1). The level of satisfaction after surgery was high in both groups. Regarding complications, there were no statistically significant differences. Isolated surgery for SUI could be considered more effective in achieving total and objective continence. However, the insertion of the TO band in both cases improves subjective urinary continence and quality of life with great safety and without differences regarding complications.

Evaluation of the effectiveness of a new surgical correction method for combined pelvic organ prolapse in women of reproductive age: A prospective non-randomized study

Aim. To evaluate the effectiveness of combined pelvic organ prolapse correction using the proposed modification of laparoscopic promontofixation of the uterus and vaginal walls using a mesh graft in women of reproductive age. Materials and methods. A prospective non-randomized study included 41 women of reproductive age (up to 49 years) with grade II–IV symptomatic combined pelvic organ prolapse. The main group (n=19) included women who underwent surgery using the proposed original method (invention patent No. RU2795649C1 dated October 27, 2022), the control group (n=22) included women who underwent conventional laparoscopic promontofixation of the uterus and vaginal walls and vaginal plasty with local tissues. The duration of surgery, intraoperative blood loss, anatomical result, effect on symptoms and sexual function were assessed using the Pelvic Floor Distress Inventory (PFDI-20), Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). Results. The duration of surgery and intraoperative blood loss were significantly lower in the main group (p=0.043 and p0.001, respectively). Anatomical success was achieved in both groups and persisted throughout the follow-up period (without statistically significant differences). Analysis of the PFDI-20 questionnaire responses showed a significant improvement in both groups with no statistically significant differences. Analysis of the PISQ-12 questionnaire data showed a significant improvement in the quality of sexual life in both groups; however, after a year of follow-up, patients of the main group had a significantly better quality of sexual life (p0.05). Conclusion. The surgical correction of combined pelvic organ prolapse using the proposed method demonstrated a good anatomical result, a decrease in intraoperative blood loss and duration of surgery, as well as an improvement in sexual function in women of reproductive age.

Two-Year Preclinical Evaluation of Long-Term Absorbable Poly-4-hydroxybutyrate Scaffold for Surgical Correction of Pelvic Organ Prolapse

Introduction and hypothesisFully absorbable implants may be an alternative to permanent meshes in the correction pf pelvic organ prolapse (POP) as they may reduce adverse events by promoting tissue regeneration and collagen metabolism. This study was aimed at evaluating the long-term host and biomechanical response to a fully absorbable poly-4-hydroxybutyrate (P4HB) scaffold in comparison with polypropylene (PP) mesh.MethodsPoly-4-hydroxybutyrate scaffold (n = 16) and PP mesh (n = 16) were surgically implanted in the posterior vaginal wall of parous female Dohne Merino sheep. Vaginal explants were evaluated in terms of gross necropsy, host response (immune response, collagen deposition, tissue regeneration), biomechanics, and degradation of P4HB at 12 and 24 months post-implantation.ResultsGross necropsy revealed no infection or fluid collection using P4HB or PP. At 12 months, exposures were observed with both P4HB (3 out of 8) and PP (4 out of 8), whereas at 24 months, exposures were observed only with PP (4 out of 8). The tensile stiffness of the P4HB explants was maintained over time despite complete absorption of P4HB. The collagen amount of the vaginal tissue after P4HB implantation increased over time and was significantly higher than PP at 24 months. P4HB scaffolds exhibited significantly lower myofibroblast differentiation than PP meshes at 24 months.ConclusionsThe P4HB scaffold allowed for gradual load transfer to the vaginal wall and resulted in mechanically self-sufficient tissue. P4HB scaffold had a more favorable host response than PP mesh, with higher collagen content, lower myofibroblastic differentiation, and no exposures at 24 months. P4HB scaffolds have potential as an alternative to permanent implants in treating POP.

Послеоперационные рецидивы пролапса тазовых органов и их комбинированная безоперационная коррекция

Objective. To study the efficacy and safety of combined (laser + electromyostimulation + pelvic floor muscle training) nonsurgical correction of pelvic organ prolapse (POP) recurrences in the late postoperative period in reproductive-aged, pre- and postmenopausal patients with different types of POP. Patients and methods. A comprehensive clinical examination, surgical treatment, and dynamic outpatient follow-up (at 1, 6, 12, 24, 36, and 48 months) of 523 patients with different types and severity of POP were performed. Disease recurrences were diagnosed in 69 (13.2%) women, 52 of whom underwent a combined non-surgical corrective therapy (laser + electromyostimulation + pelvic floor muscle training) with subsequent efficacy evaluation after 6 and 12 months. Results. Postoperative recurrences of POP were most often observed 12–36 months after surgical intervention using only own tissues (26.6%), less frequently – when synthetic implants were used (12.7%) and, extremely rarely, when titanium endoprostheses were inserted (1.6%). The positive effect of combined non-surgical correction in 32 (61.5%) women was expressed in a lower number and intensity of symptoms, improvement in the quality of life according to the PFDI-20 scale, optimization of gynecological examination data and quantitative parameters according to the POP-Q classification system. Conclusion. Combined non-surgical therapy (laser + electromyostimulation + pelvic floor muscle training) for postoperative recurrences of POP contributed to the optimization of clinical picture, dynamic improvement of the quantitative parameters of postoperative prolapse according to the POP-Q classification system, improvement of the quality of life of women, their social and sexual rehabilitation, which demonstrates the efficacy and safety of the implemented therapeutic program. Key words: postoperative recurrences of pelvic organ prolapse, combined non-surgical therapy, fractional CO2 laser, electromyostimulation, pelvic floor muscle training

Методы коррекции сочетанных форм генитального пролапса лапароскопическим доступом

Aim: to evaluate the efficacy and safety of a combined technique — pectopexy, and the most common — laparoscopic sacrocolpopexy for pelvic organ prolapse correction. Patients and Methods: the study included 32 female patients with a similar nosological form of pelvic organ prolapse. All the subjects were divided into two groups depending on the surgical treatment method. Group 1 (main group) included 14 female patients who had a combined laparoscopic correction of pelvic organ prolapse with transverse and longitudinal fixation of synthetic implants — combined pectopexy. Group 2 (control group) included 18 female patients who underwent sacrocolpopexy. Comprehensive clinical and instrumental examination of female patients was performed before and within 24 months after surgery. Results: there were no intraoperative complications in female patients of both groups. In all cases, the surgical intervention result was recognized as positive both according to the patient assessment and medical researcher assessment. There was a significant improvement in indicators reflecting the central compartment condition (apical prolapse), as well as the anterior and posterior vaginal walls. All female patients showed an improvement in their life quality. The patients also showed positive tendency according to pelvic ultrasound after surgery. No pelvic mesh complications were reported. The parameters of the Pelvic Organ Prolapse Quantification (POP-Q) system assessment did not differ significantly in female patients from both groups 1, 6, 12 and 24 months of follow-up after surgery. Conclusion: based on the obtained follow-up data, correction of central, posterior and partially anterior prolapse was achieved in patients after combined transverse and longitudinal fixation of synthetic implants. Pectopexy is safe and comparable to sacrocolpopexy, which is currently considered the most common surgery, gives a positive effect in correcting pelvic organ prolapse and improves the life quality of female patients. KEYWORDS: genital prolapse, combined laparoscopic surgery, mesh implants, surgical treatment of pelvic organ prolapse, laparoscopic sacrocolpopexy, laparoscopic pectopexy, life quality.

Унилатеральная гибридная хирургическая реконструкция тазового дна. Модифицированная лоскутная методика

Sacrospinous fixation is one of the most studied treatments for pelvic organ prolapse (POP), but the prevention of implantrelated complications remains unresolved. To isolate the mesh materials from the incision line and to prevent the development of chronic pelvic pain syndrome due to rigid fixation, a modification of hybrid pelvic floor reconstruction was performed, where a U-shaped vascularized vaginal flap acts as the main fixation point of the mesh implant. Objective. To study the efficacy and safety of a modified flap technique for unilateral hybrid pelvic floor surgical reconstruction. Patients and methods. A database of 128 case histories was generated. Inclusion criteria: apical anterior prolapse (POP-Q: Ba, C ≥ 0), hybrid pelvic floor surgical reconstruction using mesh endoprosthesis and vascularized vaginal flap performed between May 2020 and September 2022. The variables under study included POP stage, results of the PFDI-20, PISQ-12, and ICIQ-SF questionnaires, intraoperative complications. Patients who underwent surgery were invited for consultation. The following parameters were evaluated: POP stage, presence of mesh erosion, de novo dyspareunia, de novo chronic pelvic pain, de novo functional disorders (an overactive or atonic bladder, stress urinary incontinence (SUI), defecation disorders), repeat surgeries for POP and SUI. The PFDI-20, PISQ-12, and ICIQ-SF questionnaires were filled in. Satisfaction with treatment was assessed using the PGI-I scale. Four patients underwent contrast-enhanced magnetic resonance imaging of the pelvic organs. Results. The results showed a significant improvement in the quality of life after surgery in 113 (96.6%) cases. Only 3 (2.6%) patients had persistent POP symptoms. Of the 117 patients with baseline moderate or severe urinary incontinence, 45 (38.5%) showed improvement in 41 (91.1%) cases. Assessment of the quality of sexual life showed improvement in 27 (77.1%) of 35 patients, and 4 patients returned to sexual activity after surgery. Satisfaction with the results of treatment was noted in 109 (93.2%) patients. Conclusion. Flap modification for unilateral hybrid pelvic floor surgical reconstruction is an effective and safe method of preventing the development of implant-related complications in the correction of POP. Key words: pelvic organ prolapse, mesh implant, vaginal flap

Estimated National Cost of Pelvic Organ Prolapse Surgery in the United States.

To estimate the national cost of pelvic organ prolapse (POP) surgery in the United States. In this cross-sectional, population-based study, we used the 2016-2018 Healthcare Cost and Utilization Project National Inpatient Samples and National Ambulatory Surgery Samples to identify patients undergoing POP surgery using International Classification of Diseases, Tenth Revision (ICD-10) diagnosis codes, ICD-10 procedural codes, and Current Procedural Terminology codes. Cost-to-charge ratios and weighted estimates were used to calculate nationwide costs. Descriptive analysis was used to identify the sociodemographic, clinical, and surgical characteristics of the population undergoing POP surgery. Between 2016 and 2018, there were 140,762 POP surgical cases annually with an annual national cost estimated at $1.523 billion per year. The median cost per procedure increased slightly from $8,837 in 2016 to $8,958 in 2018. Overall, 82.5% of the total surgeries and 78% of the total national costs associated with POP surgery came from the ambulatory setting over this time period. Of these surgeries, 44.7% included an apical repair, and 42.3% included a concomitant hysterectomy. The average age of the population was 62 years, and 20% of the total population receiving prolapse surgery were younger than age 50 years. The annual national cost associated with surgical correction of POP is substantial, and the majority of cases occur in an ambulatory setting. These findings will contribute to enhancing cost-effectiveness analyses and decision-making processes for both health care professionals and policymakers as the national population continues to age.

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

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. 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. 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). 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.

Prediction of Pelvic Organ Prolapse Postsurgical Outcome Using Biomaterial-Induced Blood Cytokine Levels: Machine Learning Approach.

Pelvic organ prolapse (POP) refers to symptomatic descent of the vaginal wall. To reduce surgical failure rates, surgical correction can be augmented with the insertion of polypropylene mesh. This benefit is offset by the risk of mesh complication, predominantly mesh exposure through the vaginal wall. If mesh placement is under consideration as part of prolapse repair, patient selection and counseling would benefit from the prediction of mesh exposure; yet, no such reliable preoperative method currently exists. Past studies indicate that inflammation and associated cytokine release is correlated with mesh complication. While some degree of mesh-induced cytokine response accompanies implantation, excessive or persistent cytokine responses may elicit inflammation and implant rejection. Here, we explore the levels of biomaterial-induced blood cytokines from patients who have undergone POP repair surgery to (1) identify correlations among cytokine expression and (2) predict postsurgical mesh exposure through the vaginal wall. Blood samples from 20 female patients who previously underwent surgical intervention with transvaginal placement of polypropylene mesh to correct POP were collected for the study. These included 10 who experienced postsurgical mesh exposure through the vaginal wall and 10 who did not. Blood samples incubated with inflammatory agent lipopolysaccharide, with sterile polypropylene mesh, or alone were analyzed for plasma levels of 13 proinflammatory and anti-inflammatory cytokines using multiplex assay. Data were analyzed by principal component analysis (PCA) to uncover associations among cytokines and identify cytokine patterns that correlate with postsurgical mesh exposure through the vaginal wall. Supervised machine learning models were created to predict the presence or absence of mesh exposure and probe the number of cytokine measurements required for effective predictions. PCA revealed that proinflammatory cytokines interferon gamma, interleukin 12p70, and interleukin 2 are the largest contributors to the variance explained in PC 1, while anti-inflammatory cytokines interleukins 10, 4, and 6 are the largest contributors to the variance explained in PC 2. Additionally, PCA distinguished cytokine correlations that implicate prospective therapies to improve postsurgical outcomes. Among machine learning models trained with all 13 cytokines, the artificial neural network, the highest performing model, predicted POP surgical outcomes with 83% (15/18) accuracy; the same model predicted POP surgical outcomes with 78% (14/18) accuracy when trained with just 7 cytokines, demonstrating retention of predictive capability using a smaller cytokine group. This preliminary study, incorporating a sample size of just 20 participants, identified correlations among cytokines and demonstrated the potential of this novel approach to predict mesh exposure through the vaginal wall following transvaginal POP repair surgery. Further study with a larger sample size will be pursued to confirm these results. If corroborated, this method could provide a personalized medicine approach to assist surgeons in their recommendation of POP repair surgeries with minimal potential for adverse outcomes.

Topical issues of surgical treatment of pelvic floor dysfunction. A literature review

This article presents a review of the current literature on the problem of omission and prolapse of the internal genitalia in women. Patients diagnosed with pelvic organ prolapse need pelvic floor plastic surgery. Currently, in spite of the extensive experience in managing this category of patients, there is still no single and unambiguous approach to the choice of surgical treatment tactics.&#x0D; This review describes the latest information on the etiopathogenesis of pelvic floor supporting apparatus lesions, namely, systemic connective tissue dysplasia as the main development factor. Prospective development of genetic and immunohistochemical marker diagnosis is the key to individual selection of treatment options for this multidisciplinary problem. The results of interventions are characterized by extreme variability in terms of both effectiveness and the frequency of intra- and postoperative complications. The treatment of rare forms of prolapse after surgery for rectal cancer also raises many questions. The current multitude of types of surgical interventions for genital prolapse and variants of pelvic floor defect closure is constantly being modified. To date, there is no universal treatment option, and all available techniques have both advantages and disadvantages, as well as limited application due to the risk of somatic complications, high recurrence rate, and the need for expensive equipment and a highly qualified surgeon.&#x0D; New research is needed, taking into account the current knowledge about the cellular and molecular mechanism of the lesion of the pelvic floor supporting apparatus. All of this will improve the methods of correction of pelvic organ prolapse in both typical and rare forms caused by iatrogenic factors. As a result, this may lead to an improvement in the quality of life of such patients.

Laparoscopic correction of pelvic organ prolapse and stress urinary incontinence: a current view of the problem

Pelvic organ prolapse refers to a group of multidisciplinary disorders with various etiological components involved in its pathogenesis, destabilizing the ligamentous and musculofascial apparatus. In most cases, pelvic floor dysfunction requires surgical treatment, eliminating existing defects and clinical symptoms and improving patients' quality of life. Corrective surgery for genital prolapse by laparoscopic approach is highly effective and is associated with a low risk of adverse clinical outcomes. However, despite the significant progress and improvement of surgical treatment options, choosing the optimal treatment method based on a personalized approach remains an urgent issue. This literature review reviews traditional and alternative methods of laparoscopic correction of pelvic organ prolapse.

The effect of pelvic organ prolapse and various options for its correction on female sexual function: A review

The sexual activity of patients before and after the treatment of pelvic organ prolapse (POP) largely determines their quality of life and satisfaction with the intervention. This review analyzes current data on the nature of changes in sexual function in various pelvic organ prolapse correction methods. Particular attention is paid to a comparative assessment of the effect of available surgical techniques with abdominal and vaginal access on the risk of de novo dyspareunia. Based on the results of clinical studies and systematic reviews, the most optimal ways of correcting POP have been established; tools for assessing their effectiveness in routine clinical practice have been proposed; the importance of an interdisciplinary approach to the treatment of POP with the involvement of medical psychologists has been noted due to the significant role of emotional and behavioral factors in sexual dysfunction.

Prevalence and risk factors of lower urinary tract symptoms after robotic sacrocolpopexy

Aims: To analyze the prevalence and risk factors for postoperative lower urinary tract symptoms (LUTS) in women submitted to robot-assisted sacrocolpopexy (RASC) for correction of pelvic organ prolapse (POP). Methods: A longitudinal prospective study was carried out on 51 consecutive women who underwent RASC to treat POP. We recorded preoperatively the presence of LUTS urgency, symptomatic stress urinary incontinence (SUI), and voiding difficulty. We also performed an urodynamic study prior to surgical intervention including an incontinence test for overt and occult stress urinary incontinence (with POP reduction). A transobturator suburethral sling (TOT) was implanted in patients with demonstrable urodynamic SUI (overt or occult). Patients' LUTS were reassessed at 6 months after the surgical intervention. McNemar test and the Fisher exact test were used to analyzing dependent variables and Student’s t - test for independent variables. Statistical significance was set at p ≤ 0.05. Results: Postoperative voiding difficulty and symptomatic SUI were significantly reduced. No significant differences were observed in the postoperative prevalence of urgency. The presence of preoperative urinary urgency was the only significant risk factor of postoperative urgency, whereas TOT placement was the only significative factor associated with postoperative symptomatic SUI. TOT placement in patients with occult SUI significantly reduced postoperative Symptomatic SUI. Conclusion: RASC reduces the prevalence of voiding difficulty but not urgency. Concomitant implantation of TOT in patients with preoperative urodynamic SUI (overt or occult) is useful to reduce symptomatic postoperative SUI.

New-generation synthetic implants for the surgical correction of pelvic organ prolapse and stress urinary incontinence: design and testing

Introduction. Up to 50.0% of postpartum women experience stress urinary incontinence (SUI) and pelvic organ prolapse (POP). One of the most common and pathogenetically substantiated methods for surgical correction of severe SIU and POP is prosthetic reconstruction of the pelvic floor, involves the use of monofilament polypropylene surgical meshes through vaginal or laparoscopic access.. However, this way is associated with specific problems, i.e., primarily mucosal erosions, and pelvic pain. This has served as a trigger for the development of new materials that reduce the likelihood of such side effects.Objective. To develop the new-generation synthetic implants for surgical correction of stress urinary incontinence and pelvic organ prolapse.Materials and methods. The main development stages: 1. design of an experimental sample of a synthetic implant (evaluation of basic, physical and mechanical properties). 2. test of an experimental sample obtained in vitro.Results. A bioresorbable polypropylene ligature delivery system was developed and manufactured in two variants: for the POP correction (mesh tape with a width of 13 – 15 mm) and for the SUI correction (mesh tape with a width of 10 – 11 mm).Conclusion. Based on the results of the in vitro tests, we can conclude that the synthetic implants developed are able to provide physiological longitudinal (axial) support of the necessary pelvic floor sections and reduce the risk of postoperative complications. Further in vivo studies are required to assess the response of living tissue to the implantation of this type of synthetic implants.

New aspects in the surgical correction of pelvic organ prolapse

Relevance . The relevance of the problem of pelvic prolapse is due to the prevalence of the disease, the tendency to rejuvenation and progression. This, according to the survey, affects the quality of life of women, leads to disruption of sexual functioning, and reduces the ability to work. The methods of surgical treatment that exist in the arsenal of modern operative gynecology can contribute to the development of cicatricial adhesions, infectious complications and recurrence of prolapse, which creates the need for repeated interventions. The development and introduction into practice of new methods of treatment is a natural necessity. The most effective technique for the surgical treatment of genital prolapse is laparoscopic sacrocolpopexy using titanium silk implants. Materials and Methods. A prospective cohort study of 30 patients aged 37 to 74 years with clinical manifestations of grade II-IV prolapse, statistical data analysis and analysis of the results of a survey of patients in the postoperative period in dynamics over 3-6-12 months from 2019 to 2021 was carried out. The study used a three-stage method of surgical assistance (patent dated September 15, 2020 No. 2020130382/14 (054923) in the volume - laparoscopic promontofixation, MacCoul sacro-uterine ligament plasty, colporrhaphy, colpoperineorrhaphy, levatoroplasty. Results and Discussion. It has been established that pregnancy and childbirth are among the main factors provoking the development of pelvic floor muscle failure. The duration of postoperative follow-up in our study was 3-14 months. No complications were diagnosed during this period. In 12 patients (40.0 %) during the first month there were periodic pulling pains in the lower abdomen and perineum, in 2 (6.6 %) - urinary incontinence. Titanium silk has a lower affinity for surrounding tissues compared to polypropylene scaffold systems, which makes it possible to consider it as an alternative material to synthetic analogues and reduce the risk of mesh-associated complications. The resistance of the titanium endoprosthesis to antiseptics and microbial agents predisposes to its long-term use and the absence of the need for replacement. Conclusion. The data obtained make it possible to judge the high efficiency of the developed technique for the surgical treatment of pelvic prolapse of pelvic floor defects in patients with rectocele and cystocele, minimizing the recurrence of the disease and the risk of developing mesh-associated complications, which allows choosing a personalized management strategy for this cohort of patients.

Burch colposuspension is an effective additional procedure during pelvic organ prolapse surgery for prophylactic treatment of potential postoperative stress urinary incontinence.

The Impact of Race and Ethnicity on Use of Minimally Invasive Surgery for Myomas

To determine whether minimally invasive surgery (MIS) for uterine myomas is used differentially based on race and ethnicity. Retrospective cohort study. Quaternary care academic hospital in the United States. Patients undergoing hysterectomy or myomectomy for uterine myomas between March 15, 2015, and March 14, 2020 (N=1311). Cases involving correction of pelvic organ prolapse, malignancy, peripartum hysterectomy, or combined procedures with nongynecologic specialties were excluded. Racial/ethnic composition of the study population was 40.0% non-Hispanic white (white), 27.9% non-Hispanic black (black), 14.0% Hispanic, 13.7% non-Hispanic Asian (Asian), and 4.3% non-Hispanic American Indian/Alaska Native/Pacific Islander/Other. Hysterectomy, myomectomy. Of the 1311 cases, 35.9% were minimally invasive hysterectomy, 16.4% abdominal hysterectomy, 35.6% minimally invasive myomectomy, and 12.1% abdominal myomectomy. MIS rates were 94.7% among fellowship-trained minimally invasive gynecologic surgery subspecialists, 44.2% among obstetrics and gynecology specialists, and 46.8% among gynecologic oncologists. There were disparities in surgeon type based on race/ethnicity, with 59.8% of white patients having undergone surgery with a minimally invasive gynecologic surgery subspecialist vs 44.0% of black patients and 45.7% of Hispanic patients. Black and Hispanic patients were less likely to undergo MIS overall vs white patients (adjusted odds ratio [aOR] 0.33, 95% confidence interval [CI] 0.22-0.48 and aOR 0.44, 95% CI 0.28-0.72, respectively). Black and Hispanic patients undergoing hysterectomy were less likely than white patients to undergo MIS (aOR 0.33, 95% CI 0.21-0.51 and aOR 0.35, 95% CI 0.20-0.60, respectively). There were no significant differences in rates of MIS based on race/ethnicity for myomectomies nor differences in major or minor complications by race/ethnicity overall. At a quaternary care institution, black and Hispanic patients were significantly less likely than white patients to undergo MIS for uterine myomas, particularly for hysterectomy.

Unilateral pectineal suspension - A new surgical approach for apical correction of pelvic organ prolapse.

There are numerous vaginal and abdominal surgical approaches for the treatment of pelvic organ prolapse (POP). Even the standard techniques show great variability due to modifications depending on anatomy, available instruments and materials. Recently, the role of hysterectomy in prolapse surgery as well as the use of synthetic meshes have been questioned. Here, we present a standardised mesh-free minimally invasive pelvic floor reconstruction technique with uterus preservation. Unilateral pectineal suspension (UPS) is carried out in five defined steps with the use of the da Vinci Xi ® surgical system. The desired anatomical result is simulated by intraoperative uterus manipulation. The cranial part of the pectineal ligament is used for lateral fixation. A non-absorbable suture is placed between the pectineal ligament and the anterior cervix to suspend the uterus in its natural anatomical position. For outcome measurement, degree of prolapse was assessed pre- and postoperatively according to the POP-Q system. Unilateral pectineal suspension offers several advantages. Medial tension-free positioning of the uterus is achieved. The use of the cervix as fixation structure allows for excellent pelvic floor support and stable results. Normal pelvic floor mobility and natural axis of the vagina are restored. Unilateral pectineal suspension is an efficient minimal-invasive mesh-free procedure which allows uterus preservation and offers reliable level I support respecting the physiological pelvic anatomy. In addition, there is no need for ureteral dissection or bowel manipulation. The technique offers clinical standardization and can easily be integrated into the spectrum of modern surgical POP repair.
