17-Year Single Center Retrospective Review of Rate, Risk Factors and Outcomes of Lead Breakage during Sacral Neuromodulation Lead Removal.

PURPOSE: One risk of removal of a tined sacral neuromodulation lead is breakage, resulting in a retained lead fragment. We report lead breakage rates, risk factors and outcomes of retained fragments. MATERIALS AND METHODS: We report on 464 tined lead removals from 2002 to 2018. Clinical and surgical factors were reviewed and appropriate statistical analysis performed. Retained fragments were reviewed for fragment description and long-term complications. RESULTS: A total of 464 tined lead removals were included, with 35 lead breaks identified, for a rate of 7.5% (35). Factors associated with breakage included male gender (OR 6.58, 95% CI 2.54-17.01, p=0.001) and diabetes (OR 2.42, 95% CI 1.05-5.58, p=0.019). A shorter time since implantation was protective (OR 0.86, 95% CI 0.76-0.98, p=0.002). There was no difference in breakage rate based on age, weight, history of prior revision, bilateral leads, reason for lead removal, surgical technique or surgeon. Of the 35 breaks 27 had imaging available. Of these 66% (18) broke in the tined region and 81% (22) were ghost leads. Most patients (80%, 28 of 35) with retained lead fragments received another implant. Only 1 patient had a related complication of additional surgery for pain related to the fragment. CONCLUSIONS: There is a low rate of tined lead breakage during lead removal. However, it is higher than the manufacturer estimate. Protective factors include a shorter time between implant and lead revision. The most common location for lead breakage is in the region of the tines, most are ghost fragments and long-term complications are uncommon.

Can Lumbosacral Magnetic Resonance Imaging be Performed Safely in Patients with a Sacral Neuromodulation Device? An In Vivo Prospective Study.

PURPOSE: We sought to determine the safety of sacral neuromodulation in patients during lumbosacral 1.5 Tesla magnetic resonance imaging. MATERIALS AND METHODS: We prospectively recruited patients with a sacral neuromodulation implant who required lumbosacral 1.5 Tesla magnetic resonance imaging. Before imaging the patients completed validated urinary symptom questionnaires and a survey regarding the usual sacral neuromodulation sensation. The implantable pulse generator was interrogated, and impedances, battery life and stimulus amplitude sensory thresholds were assessed before and after magnetic resonance imaging. Devices were switched off before the patient entered the scanner. Patients were monitored during the study and magnetic resonance imaging related adverse events questionnaires were completed after imaging. Validated questionnaires were repeated 1 month after magnetic resonance imaging to assess for changes in sacral neuromodulation therapeutic efficacy. RESULTS: A total of 11 patients were enrolled in the study. Lower back pain, which was noted by 6 of the 11 patients (55%), was the most common indication for imaging. Immediately after magnetic resonance imaging only 1 patient reported mild discomfort during imaging at the site of the implantable pulse generator. This discomfort was present only during the scan and not afterward. Two patients reported warmth at the implantable pulse generator site during the scan, which was also present only during scanning. Patients did not report any other adverse events. There were no major changes in impedance or battery life after magnetic resonance imaging. Stimulus amplitude sensory thresholds and stimulation localization were unchanged. Validated questionnaires 1 month after imaging did not show worsening scores compared to scores before imaging. CONCLUSIONS: No significant adverse events occurred in patients implanted with a Medtronic InterStim™ II device who underwent a 1.5 Tesla lumbosacral magnetic resonance imaging scan. Therapeutic efficacy of sacral neuromodulation was unchanged 1 month after imaging.

Motor Response Matters: Optimizing Lead Placement Improves Sacral Neuromodulation Outcomes.

PURPOSE: We sought to determine the usefulness of motor responses during sacral neuromodulation lead placement by testing the hypothesis that a greater number of motor responses during intraoperative electrode testing would be associated with more durable therapy. MATERIALS AND METHODS: We retrospectively reviewed all sacral neuromodulation lead placements at a large academic center from 2010 to 2015. Included in study were all unilateral sacral lead placements for which the presence or absence of a motor response was documented discretely for each electrode. Motor responses were quantified into separate subscores, including bellows and toe response subscores (each range 0 to 4) for a possible maximum total score of 8 when combined. Revision surgery was the primary outcome. Univariate and multivariate analyses were performed for factors associated with lead revision. RESULTS: A total of 176 lead placements qualified for analysis. Mean ± SD cohort age was 58.4 ± 15.9 years, 86.4% of the patients were female and 93.2% had undergone implantation for overactive bladder. Median followup was 10.5 months (range 2 to 36). Overall 34 patients (19%) required lead revision. Revision was negatively associated with the total electrode response score (p = 0.027) and the toe subscore (p = 0.033) but not with the bellows subscore (p = 0.183). Predictors of revision on logistic regression included age less than 59 years at implantation (OR 5.5, 95% CI 2-14) and a total electrode response score less than 4 (OR 4.2, 95% CI 1.4-12.8). CONCLUSIONS: Fewer total electrode responses and specifically fewer toe responses were associated with sacral neuromodulation lead revision. These data suggest that placing a lead with more toe responses during testing may result in more durable sacral neuromodulation therapy.

Natural history of pelvic organ prolapse in symptomatic patients actively seeking treatment.

INTRODUCTION AND HYPOTHESIS: At our institution many symptomatic patients must wait months or years for surgery. Our aim was to determine the rates of clinically significant pelvic organ prolapse (POP) progression and identify risk factors associated with POP progression. METHODS: Data from a prospectively maintained database of POP patients evaluated between 2008 and 2013 were analyzed. Women with symptomatic POP and two or more POP-Q examinations prior to surgery were included. POP progression was defined as having any of the POP-Q points Aa, Ba, C, D, Ap or Bp above the hymen at the baseline examination and at or below the hymen at the follow-up examination. Multivariable logistic analysis was preformed and the results are presented as odds ratios (OR) with 95% confidence intervals (CI). RESULTS: Of consecutive patients evaluated between July 2008 and June 2013, 388 met the inclusion criteria and were included. The median time between the POP-Q examinations was 9.9 months (IQR 7.8 to 13.8 months). The POP progression rate was 29.1% (95% CI 24.6-33.6%). Predictors of progression included age (OR 1.7, 95% CI 1.01-2.87) and the baseline status of points Ba, C, Bp and gH (OR 1.91, 95% CI 1.01-3.62; OR 0.53, 95% CI 0.3-0.94; OR 0.54, 95% CI 0.32-0.93; OR 2.15, 95% CI 1.13-4.1; respectively). POP-Q point correlations showed that anterior and posterior compartment points evolve with apical compartment points and gH evolves with both the anterior compartment and the apex. CONCLUSIONS: Up to 29.1% of symptomatic patients with POP showed clinically significant progression over a median follow-up of 9.9 months. The likelihood of progression was not significantly associated with time. Those ≥60 years of age as well as those with point Ba ≥4 cm or gH ≥5 cm at baseline were at increased risk of POP progression.

Real-Time Changes in Brain Activity during Sacral Neuromodulation for Overactive Bladder.

PURPOSE: We performed functional magnetic resonance imaging to identify changes in brain activity during sacral neuromodulation in women with overactive bladder who were responsive to therapy. MATERIALS AND METHODS: Women recruited into the study had nonneurogenic refractory overactive bladder, responded to sacral neuromodulation and had had a stable program for at least 3 months with no subsequent overactive bladder treatment. Enrolled patients completed validated symptom and quality of life instruments before functional magnetic resonance imaging. Stimulus settings were recorded, devices were switched off for a 5-day washout and instruments were repeated. Three functional magnetic resonance imaging scans with simultaneous sacral neuromodulation stimulation were performed below, at and above stimulus sensory threshold using a block design. This yielded brain activity maps represented by changes in blood oxygenation level dependence. A total of 5 stimulator off and 4 stimulator on cycles of 42 seconds each were imaged. Group analysis was done using a single voxel p value of 0.05 with a false-positive error of 0.05 on cluster analysis. RESULTS: Six of the 13 patients enrolled completed functional magnetic resonance imaging. Median age was 52 years (range 36 to 64). Urinary symptoms and voiding diary data worsened with washout. Overall brain activation generally progressed with increasing stimulation amplitude. However, activation of the right inferior frontal gyrus remained stable while deactivation of the pons and the periacqueductal gray matter only occurred with subsensory stimulation. Sensory stimulation activated the insula but deactivated the medial and superior parietal lobes. Suprasensory stimulation activated multiple structures and the expected S3 somatosensory region. All devices had normal impedance after functional magnetic resonance imaging. CONCLUSIONS: Functional magnetic resonance imaging confirmed that sacral neuromodulation influences brain activity in women with overactive bladder who responded to therapy. These changes varied with stimulus intensity.

Impact of Age and Comorbidities on Use of Sacral Neuromodulation.

PURPOSE: We investigated the influence of patient age on sacral nerve stimulation trial outcomes, device implantation and treatment durability. MATERIALS AND METHODS: We analyzed a database of all sacral nerve stimulation procedures performed between 2012 and 2014 at a high volume institution for associations of patient age with sacral nerve stimulation indication, trial stimulation success, device revision and device explantation. RESULTS: In a cohort of 356 patients those with nonobstructive urinary retention and urgency-frequency were younger than patients with urgency urinary incontinence. Trial stimulation success did not differ by age in stage 1 and percutaneous nerve evaluation trials (p = 0.51 and 0.84, respectively). Logistic regression identified greater odds of trial success in females compared to males (OR 2.97, 95% CI 1.32-6.04, p = 0.009) and for urgency urinary incontinence compared to urgency-frequency (OR 3.02, 95% CI 1.39-6.50, p = 0.006). In analyzed patients there were 119 surgical revisions, including battery replacement, and 53 explantations. Age was associated with a decreased risk of revision with 3% lower odds per each additional year of age (OR 0.97, 95% CI 0.95-0.98, p <0.0001). While age did not influence explantation, for each body mass index unit there was a 5% decrease in the odds of explantation (OR 0.95, 95% CI 0.91-0.98). CONCLUSIONS: In contrast to previous studies, older patients experienced no difference in the sacral nerve stimulation response in stimulation trials and no difference in the implantation rate. Furthermore, age was modestly protective against device revision. This suggests that age alone should not negatively predict sacral nerve stimulation responses.

Vaginal hysterectomy, vaginal salpingoophorectomy and uterosacral ligament colpopexy: a view from above (in English and Spanish).

AIM OF THE VIDEO: The aim of this video is to make vaginal hysterectomy (TVH), vaginal salpingoophorectomy and uterosacral ligament (USL) colpopexy approachable by showing the key procedural steps from both the vaginal and abdominal perspectives. METHODS: This production shows TVH with salpingoophorectomy and USL colpopexy that was performed on a cadaver and filmed simultaneously from the vaginal and abdominal views. The video begins with an anatomy overview from the open abdomen and proceeds with the TVH. The anterior and posterior peritoneal entries, a technique to safely and easily access the adnexa, as well as the placement of USL suspension sutures are highlighted. The proximity of the ureter and its distance from the three locations most vulnerable to injury during this procedure (the uterine artery pedicle, the infundibulopelvic ligament and the USL) are illustrated. The location of the USL suspension sutures in relation to the ischial spine, the rectum and the sacrum are demonstrated. For all of these crucial steps, a series of picture-in-picture views simultaneously showing the abdominal and vaginal perspectives are presented so that the viewer may better understand the spatial anatomy. CONCLUSION: This video provides the viewer with a unique anatomic perspective and helps more confidently perform TVH, vaginal salpingooophorectomy and USL colpopexy.

Surgeons' views on sling tensioning during surgery for female stress urinary incontinence.

INTRODUCTION AND HYPOTHESIS: Little is known regarding the use of various techniques for sling tensioning. Our objective was to determine which techniques are most commonly used by surgeons and surgeons' views on sling tensioning. METHODS: An Internet-based survey designed to assess the use of various tensioning evaluation methods, different sling tensioning techniques, and views and beliefs regarding the importance of tensioning was sent to members of major sub-specialty professional organizations. The responses were analyzed using descriptive statistics, and univariate and multivariate logistic analyses were performed to assess the effect of various surgeon characteristics on operative techniques. RESULTS: A total of 596 surgeons (63% gynecologists, 37% urologists) from 56 different countries were included in the analysis. Over 30% of respondents reported performing >50 sling operations/year. Use of objective intraoperative tension evaluation methods was 15.6, 7.8, and 1.9% for intraoperative stress tests, cystoscopic evaluation of urethral coaptation, or Q-tip tests respectively. Sixty-three percent indicated that they tension retropubic transvaginal tape (RP) and transobturator tape (TOT) slings similarly, whereas 26.2% place more tension on TOT than RP slings and 10.4% place more tension on RP than TOT slings. Those with fellowship training were 66% more likely to utilize leak point pressure results to inform the degree of tensioning (OR 1.66, CI 1.04-2.66). CONCLUSIONS: Our results indicate that there is a wide degree of variation in technique among surgeons. Prospective studies assessing the utility of various techniques could provide more evidence-based approaches to midurethral sling surgery and potentially improve quality and patient outcomes.

Treatment of vaginal stenosis with fasciocutaneous Singapore flap.

INTRODUCTION: Vaginal stenosis is an unfortunate complication that can occur after pelvic radiation therapy for gynecologic or colorectal malignancies. Treatment is challenging and can require significant reconstructive surgery. The objective of this video is to present a case of vaginal stenosis after radiation and describe vaginal reconstruction with a fasciocutaneous Singapore flap. METHODS: We describe the case of a 42-year-old woman with a history of stage 3 colorectal cancer who underwent partial colectomy, chemotherapy, and pelvic radiation. She subsequently developed a rectovaginal fistula requiring repair with a right-sided gracilis flap. When her stenosis recurred, she underwent vaginal reconstruction with a medial thigh flap. RESULTS: The Singapore flap is a pudendal thigh flap centered on the labial crural fold with a base at the perineal body. As the cutaneous innervation is spared, this flap is sensate. This technique is one option for patients with complex vaginal stenosis who have failed conservative management. However, it is imperative the patient perform vaginal dilation postoperatively and maintain close follow-up with her surgeon, as vaginal stenosis can recur. CONCLUSIONS: Postradiation vaginal stenosis is a complex condition to treat; however, vaginal reconstruction with a thigh flap can provide excellent cosmetic and functional results.

Sacral Neuromodulation Implant Infection: Risk Factors and Prevention.

Device infection is one of the most common complications of sacral nerve stimulator placement and occurs in approximately 3-10% of cases. Infection is a serious complication, as it often requires complete explantation of the device. Not much is known regarding risk factors for and methods of preventing infection in sacral nerve stimulation. Multiple risk factors have been linked to device infection including prolonged percutaneous testing and choice of preoperative antibiotic. Methods of infection prevention have also been studied recently, including antibiotic-impregnated collage and type of skin preparation. This review will discuss the recent literature identifying risk factors and means of preventing infection in sacral nerve stimulation. Finally, we will outline a protocol we have enacted at our institution which has resulted in an incidence of infection of 1.6%.

Removal of Sacral Nerve Stimulation Devices for Magnetic Resonance Imaging: What Happens Next?

INTRODUCTION: Sacral neuromodulation (SNM) devices (Medtronic, Minneapolis, MN, USA) are not approved to undergo magnetic resonance imaging (MRI) of sites other than the head. When MRIs are required, devices are often removed prior to imaging. We reviewed the prevalence of device removal for MRI at a large academic institution and the subsequent clinical course of these patients. METHODS: A retrospective review of all SNM explants from 2009-2015 was performed. Cases explanted for MRI were analyzed to collect demographics, clinical characteristics, and postremoval management. Descriptive statistics were calculated. RESULTS: Ninety patients underwent SNM device removal, with 21 (23%) occurring for MRI. At explant, 20 patients (95%) were female and median age was 66 years. Suboptimal symptom control from SNM was noted in seven (33%) of these patients preoperatively. Of those explanted, six (29%) required MRI for neurologic and 10 (48%) for orthopedic concerns. The remaining MRI indications included abdominal masses (10%), genitourinary disease (5%), surveillance for prior malignancy (5%), and cardiac disease (5%). Only 16 (76%) patients explanted ultimately underwent MRI. MRI results impacted clinical management in 9/16 (56%) of the imaged patients. Only two (10%) of explanted patients underwent device replacement. CONCLUSIONS: In patients receiving SNM therapy, device removal for MRI is most commonly due to orthopedic and neurologic pathologies. About half of the MRIs performed impacted non-GU clinical management. It is of paramount importance to confirm the necessity of MRI before removing a functional SNM device. Since SNM replacement was rare in this cohort, research is needed on the safety of various MRI types with SNM devices in vivo.

Removal of obstructing synthetic sling from a urethra: English and Spanish version.

INTRODUCTION AND HYPOTHESIS: Urethral perforations after synthetic midurethral sling (MUS) placement are uncommon. Transvaginal removal is an option. The objective of this English and Spanish video is to demonstrate removal of an MUS that had perforated the urethra and the concomitant urethral reconstruction. METHODS: A 66-year-old woman with a history of an anterior and posterior colporrhaphy and a retropubic MUS 12 years earlier presented with difficulty voiding, recurrent urinary tract infections, and mild stress incontinence (SUI). Physical examination revealed tenderness on the anterior vaginal wall (AVW) without mesh extrusion. Cystourethroscopy showed urethral perforation, distal to the bladder neck and urodynamics demonstrated an obstructive pattern. The patient wished to undergo transvaginal sling removal and reconstruction. RESULTS: The mesh was deep in the AVW perforating the urethra and the vaginal portion was completely removed. The video demonstrates several tips on how to remove a perforating MUS and subsequent urethral reconstruction. Ten months postoperatively the force of stream returned to normal, with no further UTIs, no evidence of fistula, and rare SUI. CONCLUSIONS: Urethral perforation with an MUS can be successfully treated with removal of any mesh in proximity to the urethra and urethral reconstruction via a completely transvaginal approach.

Association between pelvic floor disorder symptoms and QoL scores with depressive symptoms among pelvic organ prolapse patients.

BACKGROUND: There is no consensus on the relationship between depressive symptoms (DS) and pelvic organ prolapse (POP) symptoms and quality of life (QoL). Our hypothesis was that women with DS and POP have worse symptoms and QoL than those without DS and POP. AIM: Our aim was to compare two groups of POP patients, those with depressive symptoms and those without, and evaluate the association of symptoms and QoL. MATERIALS AND METHODS: This planned report is part of a prospective study evaluating the impact of pessary use among symptomatic POP patients. Patients were evaluated by POP quantification (POP-Q), pelvic ultrasound (US), voiding diaries, stress test, pad test, Pelvic Floor Distress Inventory (PFDI-20), Prolapse QoL (P-QoL) and the Goldberg Health Questionnaire (GHQ-12) (psychological health screening for DS when score ≥5). A sample size of 78 patients was required to demonstrate a 50-point difference in the global PFDI-20 score with 80% power and 95% probability. RESULTS: Ninety-one women with POP were included. GHQ-12 was positive in 47 (51.6%) patients. No differences were found in POP-Q, pad and stress test between those with a positive GHQ-12 and those without. However, GHQ-12 was associated with higher PFDI-20 scores and higher scores in seven of nine P-QoL domains. GHQ-12 persisted as an independent risk factor for worse P-QoL scores after multivariable analysis. CONCLUSION: A 'positive' screening for DS was associated with worse PFDI-20 and P-QoL scores despite no difference in objective measurements. It may be that depressed patients interpret their symptoms differently.

Validation of the Spanish-language version of the Prolapse Quality of Life questionnaire in Chilean women.

INTRODUCTION AND HYPOTHESIS: The Prolapse Quality of Life (P-QOL) questionnaire is a specific health-related quality of life (HRQL) instrument to assess the impact of POP on women. It has been validated in English-speaking women and to date has been translated into several other languages. However, currently there is no Spanish translation of the P-QOL questionnaire. The aim of this study was to translate the P-QOL questionnaire into Spanish and to assess its feasibility, validity, and reliability. METHODS: Following a forward- and back-translation of the original English P-QOL questionnaire into Spanish language, the translated questionnaire was reviewed by a group of patients as well as an expert panel to assess its comprehensibility. In this cross-sectional study women with POP symptoms were recruited from a tertiary referral teaching hospital. Women were defined as symptomatic if they report feeling a lump/bulge/pressure in the vagina. The Spanish translated P-QOL questionnaire was self-administered to all women. Reliability, content, and construct validity were evaluated using the Cronbach's alpha coefficient, ANOVA, and Spearman's correlation tests. RESULTS: One hundred and twenty-eight women were studied. There were no missing items. The Cronbach's alpha ranged from 0.626 to 0.866 across domains, demonstrating the good reliability of the Spanish P-QOL. The severity of symptoms was related to the worst quality of life, but the severity of POP was not related to poorer QoL. CONCLUSIONS: The Spanish translated version of the P-QOL is a reliable, consistent and valid instrument to assess symptom severity and QoL impact in Chilean women with POP.

Labhardt's colpoperineocleisis: subjective results of an alternative treatment for genital prolapse in patients who are not sexually active--2-year follow-up.

INTRODUCTION AND HYPOTHESIS: Genital prolapse affects up to 50 % of multiparous women and has an impact on quality of life (QoL) for many. Vaginal obliterative techniques are relevant in older patients who are not sexually active. We performed Labhardt's colpoperineocleisis in such patients. The objective was the evaluation of subjective outcomes of this technique using PGI-I. METHODS: Retrospective cohort analysis of patients. We performed a bivariate, multivariate analysis, and survival curves for subjective improvement. RESULTS: Seventy-four cases were analyzed. Average age of the patients was 72 years, median parity 4, 95.9 % POP-Q stage III or IV, anterior leading edge defect in 61.1 %. Operating time: 54 min, estimated blood loss 70 ml, no intraoperative complications, 12 patients had protocol deviations with changes in the recommended type of suture. Median hospital stay was 2 days and average follow-up 24.9 months. There was 13.5 % anatomical recurrence, 3 of which (30 %) were in patients with protocol deviations. 1.9 % developed clinically significant de novo stress urinary incontinence (SUI). PGI-I: 64 (86 %) reported subjective improvement and 10 did not. In the subjective improvement group, 98.4 % reported being very much or much better. In the non-subjective improvement group 80 % reported that they were the same as before surgery and 20 % were worse. In bivariate analysis anatomical recurrence showed significance and persisted after multivariate analysis with an OR of 8322 for subjective failure. CONCLUSION: Labhardt's colpoperineocleisis is a safe technique with good subjective results. It has few complications, an acceptable recurrence rate, and a low rate of de novo SUI. It may be important to use the #0 or #1 polydioxanone sutures, as these are associated with better outcomes in this series. Comparative studies with other obliterative techniques are needed.

Prevalence of colorectal symptoms and anal incontinence in patients with pelvic organ prolapse attended at an outpatient urogynecology service.

Objective: To analyze data of patients with symptomatic pelvic organ prolapse evaluated with PFDI20 and its subscales to report the prevalence of lower gastrointestinal symptoms and anal incontinence in the population of a public hospital and analyze its impact on quality of life. Methods: Cross-sectional study of patients with symptomatic POP. Patients were evaluated with demographic data, POP-Q, pelvic floor ultrasonography, urological parameters, and pelvic floor symptoms (PFDI-20), and quality of life (P-QoL) surveys. Patients were classified as CRADI-8 "positive" for colorectal symptoms, with responses "moderate" in at least 3 and/or "severe" in at least 2 of the items in the CRADI-8 questionnaires. Results: One hundred thirteen patients were included. 42.5% (48) were considered positive for colorectal symptoms on CRADI-8. 53.4% presented anal incontinence. No significant differences were found in sociodemographic variables, POP-Q stage, ultrasound parameters, or urological parameters. Positive patients had a significantly worse result in PFDI-20, POPDI (48 vs 28; p<0.001), UDI6 (51 vs 24; p<0.001), and in the areas of social limitation (44.4 vs 22.2; p = 0.045), sleep- energy (61.5 vs 44.4; p = 0.08), and severity (56.8 vs 43.7, p=0.015) according to P-QoL. Conclusion: Moderate or severe colorectal symptoms are seen in 40% of patients with symptomatic POP in our unit. Full evaluation of pelvic floor dysfunction symptoms should be performed routinely in urogynecology units.(FONIS SA12I2I53 - NCT02113969).

Sacral neuromodulation therapy for urinary and defecatory disorders: experience in a Latin American public hospital.

Objective: To show the experience of a Latin American public hospital, with SNM in the management of either OAB, NOUR or FI, reporting feasibility, short to medium-term success rates, and complications. Methods: A retrospective cohort was conducted using data collected prospectively from patients with urogynecological conditions and referred from colorectal surgery and urology services between 2015 and 2022. Results: Advanced or basic trial phases were performed on 35 patients, 33 (94%) of which were successful and opted to move on Implantable Pulse Generator (GG) implantation. The average follow-up time after definitive implantation was 82 months (SD 59). Of the 33 patients undergoing, 27 (81%)reported an improvement of 50% or more in their symptoms at last follow-up. Moreover, 30 patients (90%) with a definitive implant reported subjective improvement, with an average PGI-I "much better" and 9 of them reporting to be "excellent" on PGI-I. Conclusion: SNM is a feasible and effective treatment for pelvic floor dysfunction. Its implementation requires highly trained groups and innovative leadership. At a nation-wide level, greater diffusion of this therapy among professionals is needed to achieve timely referral of patients who require it.

Levator Ani Avulsion in Ultrasound Increases Recurrence in Sacrospinous Fixation.

IMPORTANCE: Pelvic floor translabial ultrasound (TLUS) can identify levator ani muscle (LAM) avulsion and ballooning, which some studies have shown to be possible risk factors for prolapse recurrence. Our group uses TLUS to counsel patients preoperatively. If any of these risk factors exist, we offer sacrocolpopexy over vaginal repair. However, some patients, even though they have these possible risk factors, prefer to undergo vaginal surgery. OBJECTIVE: The objective of this study was to determine if TLUS LAM avulsion and/or ballooning are risk factors for composite outcome recurrence in patients undergoing sacrospinous ligament fixation for pelvic organ prolapse. STUDY DESIGN: This was a retrospective observational study. All patients with vaginal apical repair with sacrospinous ligament fixation with preoperative TLUS were included. Demographics, clinical characteristics, and follow-up were analyzed. Multivariable logistic regression analysis was performed for composite outcome that included TLUS risk factors, age, Pelvic Organ Prolapse Quantification System measurements and stage, and variables with P < 0.1 in the univariate analysis. RESULTS: Eighty-two patients were included. All patients had symptomatic vaginal bulge; 65.4% had stage III prolapse. Concomitant hysterectomy was performed in 54.3%. Median follow-up was 20 months (interquartile range, 8-35 months); 19.8% had LAM avulsion, and 43.2% had ballooning. Anatomic recurrence rate was 23.5%, symptomatic was 22.2%, and reoperation was 1.2%. The composite recurrence rate was 29.6%. In the multivariable logistic regression analysis, unilateral/bilateral avulsion in TLUS was found to be a significant risk factor for composite outcome with an odds ratio of 4.33 (confidence interval, 1.219-15.398; P = 0.023). CONCLUSIONS: Composite outcome of recurrence in our study was 29.6%. Avulsion on TLUS increased the risk of recurrence of pelvic organ prolapse by fourfold.
