Urodynamic insights: exploring the relationship between detrusor overactivity and pelvic organ prolapse in women with urge incontinence.

PURPOSE: Pelvic organ prolapse (POP) and overactive bladder (OAB) commonly affect the aging female population. We aimed to investigate the possible relationship between the two, as reflected by urodynamic studies. METHODS: A retrospective analysis was conducted on women who underwent urodynamic studies at a university-affiliated tertiary medical center from January 2018 to January 2021. Women presenting with urge incontinence and diagnosed with detrusor overactivity (DO) were included in the study. Based on the presence or absence of a modified POP-Q ≥ grade 2, these women were categorized into two groups. Data on general demographics, clinical symptoms, and urodynamic findings were extracted and compared using SPSS. RESULTS: During the study period, 949 urodynamic evaluations were performed. Of these, 303 (31.92%) reported urge incontinence. Out of this subset, 151 (49.83%) were diagnosed with DO. Within this group, 18 (11.9%) had POP, while 134 (88.1%) did not. The POP group had a notably higher incidence of prior vaginal hysterectomy and anterior colporrhaphy (p = 0.02 and p = 0.01, respectively). While most urodynamic parameters were similar between groups, there was a significant increase in hesitancy in the POP group (13 s vs 8 s, p = 0.03). There was a trend indicating a reduced median Q max (12 ml/s vs. 18 ml/s, p = 0.06) and an increased flow time (55 s vs 40 s, p = 0.08) in the POP group. CONCLUSION: The urodynamic profile of the POP group suggests an obstructive voiding pattern. Further longitudinal research is essential to fully understand the relationship between POP and OAB.

Maintaining the apex: a novel technique for vault suspension during vaginal hysterectomy.

INTRODUCTION AND HYPOTHESIS: Post-hysterectomy vault prolapse poses significant challenges to patients and surgeons alike. Despite numerous surgical interventions during initial vaginal hysterectomy to counteract this, a comparative analysis of their efficacy is limited. This study introduces a pioneering technique intended to avert vault prolapse during vaginal hysterectomy by harmoniously merging level 1 and level 2 support. METHODS: After obtaining informed consent, we recorded a variation of the McCall technique performed during vaginal hysterectomy and anterior repair. Patient follow-ups were conducted up to 6 months post-operation to evaluate anatomical outcomes and quality of life. RESULTS: A total of 46 women underwent the surgery. Anatomical evaluations at the 6-month mark were commendable, with no recurrence instances. Quality-of-life assessments, using the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-12 (PISQ-12), showcased substantial improvement. CONCLUSION: Our novel approach to vault suspension provides an uncomplicated, easily impartible, surgical procedure utilizing standard sutures. We believe that this approach is both enduring and safe.

Robot-assisted laparoscopic pelvic floor surgery: Review.

Minimally invasive surgical techniques have become more common in pelvic floor reconstructive urogynaecological surgery, specifically, robotic-assisted pelvic floor surgery. Female pelvic floor anatomy is complex, and some repairs require highly experienced surgical skills that can be gained more easily using robotic-assisted surgery. A common application of the robotic platform in urogynaecological surgeries includes sacrocolpopexy, which has become the gold standard approach in the last decade for the correction of apical prolapse. Additional procedures include sacrohysteropexy, sacrocervicopexy, fistula repair, and complex procedures involving the bladder and other pelvic organs. Despite its increasing use and clear benefit in our field, data in the literature and, in particular, randomised controlled trials are sparse. This review provides an update, incorporating recently published literature and our personal experience in that field.

A cost-effective model for training in Robot-Assisted Sacrocolpopexy.

BACKGROUND: The number of robotically assisted sacrocolpopexy procedures are increasing; therefore, experienced clinicians are needed. Simulation-based cadaver models are challenging in aspects of cost and availability. Therefore, we need to look at alternative and more cost-effective models. OBJECTIVE: The objective of this video was to design a new surgical model for the training of robotic-assisted sacrocolpopexy, which is affordable and accessible. METHODS: We used a whole chicken model to simulate the female pelvic floor. We used Medtronic's Hugo™ RAS system as the robotic console in that procedure. A vaginal cuff was prepared from the proventriculus (stomach), and a Y shaped mesh was secured to the ischium to simulate the sacrocolpopexy procedure. CONCLUSION: This model is easily constructed and in our view is cost-effective. We have demonstrated a new valuable education tool that can serve as a practical simulation model to teach the sacrocolpopexy procedure and to improve trainees' skills. A larger cohort study size is essential to demonstrate the learning curve among young trainees using this simulation model.

Robot-assisted pelvic floor reconstructive surgery: an international Delphi study of expert users.

BACKGROUND: Robotic surgery has gained popularity for the reconstruction of pelvic floor defects. Nonetheless, there is no evidence that robot-assisted reconstructive surgery is either appropriate or superior to standard laparoscopy for the performance of pelvic floor reconstructive procedures or that it is sustainable. The aim of this project was to address the proper role of robotic pelvic floor reconstructive procedures using expert opinion. METHODS: We set up an international, multidisciplinary group of 26 experts to participate in a Delphi process on robotics as applied to pelvic floor reconstructive surgery. The group comprised urogynecologists, urologists, and colorectal surgeons with long-term experience in the performance of pelvic floor reconstructive procedures and with the use of the robot, who were identified primarily based on peer-reviewed publications. Two rounds of the Delphi process were conducted. The first included 63 statements pertaining to surgeons' characteristics, general questions, indications, surgical technique, and future-oriented questions. A second round including 20 statements was used to reassess those statements where borderline agreement was obtained during the first round. The final step consisted of a face-to-face meeting with all participants to present and discuss the results of the analysis. RESULTS: The 26 experts agreed that robotics is a suitable indication for pelvic floor reconstructive surgery because of the significant technical advantages that it confers relative to standard laparoscopy. Experts considered these advantages particularly important for the execution of complex reconstructive procedures, although the benefits can be found also during less challenging cases. The experts considered the robot safe and effective for pelvic floor reconstruction and generally thought that the additional costs are offset by the increased surgical efficacy. CONCLUSION: Robotics is a suitable choice for pelvic reconstruction, but this Delphi initiative calls for more research to objectively assess the specific settings where robotic surgery would provide the most benefit.

Correlation between Mediterranean diet, bowel function, and isolated posterior vaginal defect: A cross-sectional study.

OBJECTIVE: Isolated posterior prolapse is a unique entity that was previously linked to chronic obstructive defecation. Our objective is to evaluate the relationship of low adherence to a Mediterranean diet (LAMD) with bowel dysfunction and isolated posterior compartment prolapse (IPCP). METHODS: This multicenter, cross-sectional study compared the dietary outcomes (validated Mediterranean diet [MD] questionnaire) of women who underwent pelvic organ prolapse (POP) repair surgery between August 2020 and October 2021. RESULTS: Among 204 patients enrolled, 108 (52.9%) patients adhered to the MD and 96 (47.0%) did not. Among the LAMD patients, increased symptoms of constipation (P = 0.047) and higher body mass index (P < 0.001) were more prevalent. Surgical repairs of the posterior compartment, combined (P = 0.033) and isolated (P = 0.021), were more prevalent in the LAMD group. Prolapse of all compartments except the apical compartment was found to be more prevalent in the LAMD group. Multivariate logistic regression analysis was found to be significant as a protective factor for the primary outcome (IPCP). CONCLUSION: Low adherence to a Mediterranean diet displays a higher prevalence of posterior vaginal defects, both isolated and combined. Hence, we can conclude that LAMD and subsequent bowel dysfunction are significant contributory factors to the prolapse of the posterior vaginal compartment.

Can obesity impact mesh exposure rate after mid-urethral sling operation? Medium term follow-up.

OBJECTIVE: To study mesh exposure rates among obese (BMI ≥ 30 kg/m2) vs non-obese women after mid-urethral sling (MUS) operation. STUDY DESIGN: This retrospective cohort study included all patients who underwent MUS surgery for stress urinary incontinence April 2014-April 2021 in a tertiary-level university hospital. Data from obese and non-obese patients were compared. RESULTS: A total of 120 (41 %) obese patients and 172 (59 %) non-obese patients who had mid-urethral sling surgery were compared. Of the cohort, 265 (90.7 %) underwent TVT-obturator, 15 (5.1 %) mini-sling TVT, and 12 (4.1 %) retro-pubic TVT. Diabetes mellitus was significantly more prevalent in the obese group (p =.01), without other demographic differences. Mesh post-operative exposure rate was 5.4 % during the study. The obese group had lower incidence of mesh exposure than the non-obese group (1.6 % vs 8.1 % respectively, p =.018). Mean follow-up was 51 months (range 8-87 months) without significant differences between groups (49.9 ± 21.2 vs 51.5 ± 22.3, p =.548). Pelvic organ prolapse, cystocele, and rectocele stages were significantly higher in non-obese patients. Similar numbers of post-menopausal women were in each group. CONCLUSION: This follow-up after MUS surgery showed an association between obesity and lower rate of mesh exposure. Further research is needed to evaluate correlations between estrogen and mesh exposure.

What Does Your Pelvic Floor Do for You? Knowledge of the Pelvic Floor in Female University Students: A Cross-sectional Study.

OBJECTIVES: To assess the knowledge of the pelvic floor in female university students, including knowledge of pelvic floor structure, function, pelvic floor dysfunction, and pelvic floor muscle exercises (PFMEs). METHODS: The study design is a cross-sectional study via online questionnaire with convenience sampling of female students registered at University College Cork, Ireland for the academic year 2018 to 2019. An online questionnaire was distributed to students at their registered email addresses. Overall knowledge was assessed through 15 questions, looking at pelvic floor structure, function, pelvic floor dysfunction and PFMEs. A score of 1 was allocated to each correct question, with a maximum possible score of 15. Only respondents who answered all 15 questions were included in the analysis. Ethical approval was granted by the Clinical Research and Ethics Committee, Cork, Ireland, on January 4, 2019. RESULTS: Nine hundred thirty-eight responses were received. There were 72.6% (n = 640) students who had never received information on the pelvic floor. There were 83.9% (n = 691) students who reported that they thought it was important to exercise the pelvic floor. The mean overall knowledge score of 792 respondents was 9.57 (SD, ± 2.72). There was a statistically significant difference (P < 0.001) in the overall knowledge between the students in the school of medicine and health (n = 307, mean = 11.8, SD = 2.35) and the students of other schools (n = 529, mean = 9.39, SD = 2.88). CONCLUSIONS: Knowledge of the pelvic floor in female university students is poor. Further interventions should aim to improve knowledge of the pelvic floor and encourage correct performance of PFMEs in college students.

Prospective comparative study of the effects of lidocaine on urodynamic and sensory parameters in bladder pain syndrome.

INTRODUCTION AND HYPOTHESIS: Intravesically administered lidocaine is used in patients with bladder pain syndrome (BPS) to test the hypothesis that symptoms have a peripheral versus central mechanism. METHODS: A cross-sectional study of 24 female patients with BPS was performed. The Central Sensitisation Inventory (CSI) and Kings Health Questionnaire (KHQ) were completed. Urodynamic assessment was undertaken. Women were asked to report their pain using a numeric rating scale at cystometric capacity and post void. Participants then received an intravesical instillation of either 20 ml of 2% alkalinised lidocaine (n = 16) or 20 ml of normal saline (n = 8). These solutions were allowed to remain in situ for 20 min and pain score repeated. Urodynamics was repeated. RESULTS: There was a statistically significant volume increase following lidocaine treatment: maximal cystometric capacity (MCC) 192-261 ml post lidocaine (p = 0.005.) In contrast, there was no significant difference in the saline controls: MCC 190-183 ml (p = 0.879.) Individual analysis revealed five of 16 lidocaine participants did not respond to lidocaine. These five reported a significantly worse quality of life (QoL) than lidocaine responders and had a tendency towards central sensitivity syndromes. CONCLUSION: Lidocaine significantly improved MCC in 11/16 participants in this study. These patients appear to have peripherally mediated disease. However, the failure of response to treatment in five participants, as well as their tendency towards central sensitivity syndromes, implies that in this subgroup, a peripheral drive from the bladder is not critical to their pain, suggesting central nervous system (CNS) pathology. This simple and safe test could be used to stratify patients for research or therapeutic trials.

The long-term effects of bariatric surgery on female urinary incontinence.

INTRODUCTION: Obesity has been shown to negatively impact pelvic floor support and associated urinary incontinence (UI), however little is known regarding the long-term effect of bariatric surgery on urinary incontinence. OBJECTIVE: The aim of this study is to determine the impact of bariatric surgery on female UI at twelve months post-operatively. STUDY DESIGN: A prospective cohort study was performed of all patients undergoing bariatric surgery who reported UI between January 2008 to January 2017. RESULTS: Three hundred and sixty-six women undergoing bariatric surgery and filled out the ICIQ-UI SF questionnaire. Of these 44% (151/366) had UI pre-operatively, and of these 40% (61/151) completed the questionnaire at one year post-operatively. The mean pre-operative weight and body mass index (BMI) were 136 (21.3)kg and 51 (7.1) kg/m2 respectively. The percentage excess weight loss was 74%. Sixty-six percent underwent laparoscopic gastric bypass, and the remainder underwent sleeve gastrectomy. Thirty-four percent reported stress incontinence (SUI), 21% reported overactive bladder (OAB), and 44% reported mixed incontinence. The cure rates post-operatively for SUI, OAB and mixed incontinence, were 41%, 38% and 48% respectively, and there was a 40% improvement in UI when assessing pad use (p < 0.001). Using the ICIQ-UI SF, the mean score was reduced by 4.8 (5), from 9.3 (4) pre-operatively to 4.5 (5) post-operatively. CONCLUSION: Bariatric surgery results in a clinically significant long-term improvement in UI, with a significant cure rate at one year post bariatric surgery. The improvement in severity score, based on the Incontinence Questionnaire used, did not correlate with reduction in post-operative BMI.

What is to blame for postnatal pelvic floor dysfunction in primiparous women-Pre-pregnancy or intrapartum risk factors?

BACKGROUND: The aetiology of pelvic floor dysfunction (PFD) is still poorly understood. However childbearing is recognized as a major risk factor. OBJECTIVES: To elucidate the natural history of PFD by investigating the impact of the mode of delivery on postnatal pelvic floor dysfunction in primiparas, when PFD existing before the first pregnancy is taken into consideration. STUDY DESIGN: 4P-study (Prevalence and Predictors of Pelvic floor dysfunction in Primips) is a prospective cohort study, nested within the Screening for Pregnancy Endpoints (SCOPE) study set in a tertiary referral teaching hospital with 9000 deliveries annually. Established and proposed risk factors for urinary, fecal, prolapse and sexual dysfunction and the severity of symptoms for each of these outcomes were assessed using the Australian Pelvic Floor Questionnaire in 1482 nulliparous women, who each completed the questionnaire in early pregnancy. Of these, 1060 (72%) repeated the questionnaire 12 months postpartum.Outcomes were analyzed using multivariate ordinal logistic regression. RESULTS: Significant (p<0.05) risk factors for postpartum PFD were pre-pregnancy presence of similar symptoms Odds Ratio (OR) (5.0-30.0), smoking (OR 2.2-4.6), recurrent UTI (OR 2.2-17.3), high hip circumference (OR1.4-1.6), vigorous exercising (OR 3.1-17.9), induction of labor (OR 1.5-2.3), forceps delivery (OR 1.8-8.8), and 3rd degree perineal tear (OR 2.4-2.7). Cesarean section was associated with a lower risk of stress urinary incontinence (OR 0.3-0.5). Other common pre-pregnancy significant (p<0.05) risk factors for various PFD types prior to the first pregnancy were: diagnosed depression - (OR 1.6-2.1), high BMI (OR 3.1), strenuous exercising (OR 1.3-2.2), recurrent UTI (OR 1.5-2.5) and lower educational achievement (OR 1.5-1.6). CONCLUSIONS: Pre-pregnancy PFD was mainly associated with modifiable risk factors such as smoking and exercising. The main risk factor for postpartum PFD was the presence of similar symptoms prior to pregnancy, followed by anthropometric and intrapartum factors. Hip circumference seems to be a better predictor of PFD compared to BMI. When pre-pregnancy PFD was included in the analysis, Cesarean section was protective only for stress urinary incontinence, while delivery by forceps increased the risk of prolapse.

Role of robotics in managing mesh and suture complications of prior pelvic organ prolapse surgery.

Robotic surgery is proving essential in providing a minimally invasive approach to complex urogynaecological cases. This video highlights the diversity and complexity of cases performed using the robot-assisted approach. The robot-assisted approach was utilised for excellent effect in two complex urogynaecological cases. In the first case the entire left arm of an intravesically placed TVT was removed using a combined vaginal and robotic approach. The second case involved removing four paravaginal sutures, one of which breeched the bladder and was encrusted with calculus. These were placed during a laparoscopic paravaginal repair 2 years previously. She had a concomitant vaginal hysterectomy, Mc Calls culdoplasty and anterior wall repair. The robot-assisted approach allows for excellent access to the pelvis and retropubic space facilitating the surgical management of complex urogynaecology cases.

Manipulating the extracellular matrix: an animal model of the bladder pain syndrome.

Bladder pain syndrome (BPS) is associated with breakdown of the protective uroepithelial barrier of the urinary bladder allowing urinary constituents access to bladder sensory neurons. Although there are several animal models of cystitis, none specifically relates to BPS. Here, we aimed to create such a model using enzymatic digestion of the barrier proteoglycans (PGs) in the rat. Twenty female Wistar rats were anaesthetized and transurethrally catheterized. Ten animals were treated with 0.25IU of intravesical chondroitinase ABC and heparanase III to digest chondroitin sulphate and heparin sulphate PGs, respectively. Ten animals received saline. Following PG deglycosylation, bladders showed irregular loss of the apical uroplakin and a significant increase in neutrophils, not evident in the control group. Spinal cord sections were also collected for c-fos analysis. A large and significant increase in fos immunoreactivity in the L6/S1 segments in the treatment vs control bladders was observed. Cystometry was performed on 5 treatment and 5 control animals. Analysis revealed a significant increase in micturition reflex excitability postdeglycosylation. On a further group of 10 animals, von Frey mechanical withdrawal thresholds were tested on abdominal skin before and after PG digestions. There was a significant decrease in abdominal mechanical withdrawal threshold postdeglycosylation compared with controls. The results of this animal study suggest that many of the clinical features of BPS are seen after PG digestion from the bladder lumen. This model can be used to further understand mechanisms of pain in patients with BPS and to test new therapeutic strategies.

Sacrocolpopexy for pelvic organ prolapse: evidence-based review and recommendations.

Sacrocolpopexy is considered a reference operation for pelvic organ prolapse repair but its indications and technical aspects are not standardized. A faculty of urogynecology surgeons critically evaluated the peer-reviewed literature published until September 2015 aiming to produce evidence-based recommendations. PubMed, MEDLINE, and the Cochrane Library were searched for randomized controlled trials published in English language. The modified Oxford data grading system was used to access quality of evidence and grade recommendations. The Delphi process was implemented when no data was available. Thirteen randomized, controlled trials were identified, that provided levels 1 to 3 of evidence on various aspects of sacrocolpopexy. Sacrocolpopexy is the preferred procedure for vaginal apical prolapse (Grade A), monofilament polypropylene mesh is the graft of choice and the laparoscopic approach is the preferred technique (Grade B). Grade B recommendation supports the performance of concomitant procedures at the time of sacrocolpopexy. Grade C recommendation suggests either permanent or delayed sutures for securing the mesh to the vagina, permanent tackers or sutures for securing the mesh to the sacral promontory and closing the peritoneum over the mesh. A Delphi process Grade C recommendation supports proceeding with sacrocolpopexy after uncomplicated, intraoperative bladder or small bowel injuries. There is insufficient or conflicting data on hysterectomy (total or subtotal) or uterus preservation during sacrocolpopexy (Grade D). Sacrocolpopexy remains an excellent option for vaginal apical prolapse repair. The issue of uterine preservation or excision during the procedure requires further clarification. Variations exist in the performance of most technical aspects of the procedure.

The Expression of Inflammatory Mediators in Bladder Pain Syndrome.

BACKGROUND: Bladder pain syndrome (BPS) pathology is poorly understood. Treatment strategies are empirical, with limited efficacy, and affected patients have diminished quality of life. OBJECTIVE: We examined the hypothesis that inflammatory mediators within the bladder contribute to BPS pathology. DESIGN, SETTING, AND PARTICIPANTS: Fifteen women with BPS and 15 women with stress urinary incontinence without bladder pain were recruited from Cork University Maternity Hospital from October 2011 to October 2012. During cystoscopy, 5-mm bladder biopsies were taken and processed for gene expression analysis. The effect of the identified genes was tested in laboratory animals. OUTCOME MEASURES AND STATISTICAL ANALYSIS: We studied the expression of 96 inflammation-related genes in diseased and healthy bladders. We measured the correlation between genes and patient clinical profiles using the Pearson correlation coefficient. RESULTS AND LIMITATIONS: Analysis revealed 15 differentially expressed genes, confirmed in a replication study. FGF7 and CCL21 correlated significantly with clinical outcomes. Intravesical CCL21 instillation in rats caused increased bladder excitability and increased c-fos activity in spinal cord neurons. CCL21 atypical receptor knockout mice showed significantly more c-fos upon bladder stimulation with CCL21 than wild-type littermates. There was no change in FGF7-treated animals. The variability in patient samples presented as the main limitation. We used principal component analysis to identify similarities within the patient group. CONCLUSIONS: Our study identified two biologically relevant inflammatory mediators in BPS and demonstrated an increase in nociceptive signalling with CCL21. Manipulation of this ligand is a potential new therapeutic strategy for BPS. PATIENT SUMMARY: We compared gene expression in bladder biopsies of patients with bladder pain syndrome (BPS) and controls without pain and identified two genes that were increased in BPS patients and correlated with clinical profiles. We tested the effect of these genes in laboratory animals, confirming their role in bladder pain. Manipulating these genes in BPS is a potential treatment strategy.

Managing novel orally administered anticoagulants in patients undergoing urogynaecological surgery.

The use of novel orally administered anticoagulant agents (NOACs) provides new challenges to clinicians in the perioperative care of patients undergoing urogynaecological surgery. We aimed to assess evidence for managing patients taking NOACs before and after urogynaecological surgery. We conducted a literature search in CINAHL, MEDLINE, CENTRAL, Cochrane Library and PubMed for original research articles in the English language on this topic. However, despite initially identifying 556 articles, no articles pertained to the use of NOACs in urogynaecological surgery. We subsequently reviewed national and international guidance on managing patients prescribed NOACs and created a concise guideline to aid urogynaecologists in the perioperative care of these patients. Consensus is needed on perioperative optimisation of anticoagulation in urogynaecological patients using NOACs.

Sacrocolpopexy: is there a consistent surgical technique?

INTRODUCTION: Sacrocolpopexy is the gold standard treatment for vault prolapse. Current reported standards regarding surgical approach and technique vary. Our aim was to evaluate the surgical techniques used and identify any consistency. METHODS: Electronic surveys were sent to 148 candidates enrolled in a sacrocolpopexy workshop at the 2012 American Urogynecologic Society (AUGS) annual meeting and as a link in the International Urogynecology Association (IUGA) e-magazine. The survey assessed demographics, specific surgical steps including dissection techniques, number and type of sutures, graft materials, and the approach to intraoperative complications. RESULTS: Within the AUGS group, 61 candidates responded (41 %). From the IUGA membership, 128 responded for a total of 189. Overall, 59 % identified their primary practice as urogynaecology, 43 % having completed a fellowship. Only 33 % reported performing sacrocolpopexy as the primary surgery for vault prolapse. Technical aspects: 99.4 % used polypropylene mesh, with 57 % attaching it to the vagina using non-absorbable monofilament sutures. An average of 3-4 sutures were used on the anterior and posterior walls respectively. Suture location: 22.5 % reported not placing apical sutures and 55.7 % place their anterior wall sutures midway down the vagina. Posteriorly, 47 (30 %) placed sutures through the uterosacral ligaments, 19 (12.4 %) through the levator ani and 15 % extend the mesh to the perineal body. The mesh was attached to the sacrum using permanent sutures by 75 %. Dissection of the sacrum was deemed the most technically difficult aspect. CONCLUSION: Surgical technique varies widely despite the level of expertise and training. This study highlights the need for an evaluation of the effect of surgical technique on outcomes.

Robot-assisted hysterectomy compared to open and laparoscopic approaches: systematic review and meta-analysis.

PURPOSE: To review the safety and effectiveness of robot-assisted hysterectomy compared to traditional open and conventional laparoscopic surgery, differentiating radical, simple total with node staging, and simple total hysterectomy. METHODS: Medline, Embase, the Cochrane library, and the Journal of Robotic Surgery were searched for controlled trials and observational studies with historic or concurrent controls. Data were pooled using random effects meta-analysis. RESULTS: Compared to open surgery, robot-assisted radical hysterectomy is associated with reduced hospital stay and blood transfusions. For simple total hysterectomy with node staging, robot-assisted surgery is associated with reduced hospital stay, complications, and blood transfusions compared to open surgery. Compared to conventional laparoscopic surgery, robot-assisted simple total hysterectomy with node staging is associated with complications and conversions. CONCLUSIONS: Compared to open surgery, robot-assisted hysterectomy offers benefits for reduced length of hospital stay and blood transfusions. The best evidence of improved outcomes is for simple total hysterectomy with node staging. Study quality was poor.
