Outcomes of Mid-Urethral Sling for Urodynamic Stress Incontinence Following Extensive Pelvic Reconstructive Surgery.

INTRODUCTION AND HYPOTHESIS: To assess the outcomes of mid-urethral sling (MUS) procedures for urodynamic stress incontinence (USI) following extensive pelvic reconstructive surgery (PRS) and identify risk factors for persistent USI (P-USI). METHODS: This retrospective study analyzed 84 women who underwent a staged approach to MUS for USI after PRS for advanced pelvic organ prolapse (Pelvic Organ Prolapse Quantification III and IV). The primary outcome was objective cure rate, defined by negative urine leakage on urodynamic study and a 1-h pad test weight of < 2 g. Subjective cure rate was through a negative response to question 3 of UDI-6. RESULTS: The overall objective cure rate was 81.0%. The highest cure rate was observed in de novo USI (MUS-D; 89.7%) compared with women with persistent USD (MUS-P). Patients with overt SUI exhibited lower cure rates than those with occult SUI. Predictive factors for persistent USI were lower pre-operative maximum urethral closure pressure (MUCP; p = 0.031) and higher BMI in the MUS-P group than in the MUS-D group (p = 0.008). Subjective improvement was noted, especially in the MUS-D group, with a subjective cure rate of 78.6%. Those with MUS-D reported a higher impact on patient well-being post-surgery. No complications were observed after MUS surgery at follow-up. CONCLUSIONS: Overt USI, low MUCP and high BMI are independent predictors of persistent USI after a staged MUS approach after pelvic reconstructive surgery.

Single incision mini sling for the treatment of urodynamic stress incontinence: Surgical outcomes and preoperative predictors of failure.

OBJECTIVE: To evaluate the surgical outcomes and predictors of failure of Single Incision Mini Sling (Ophira) in women with urodynamic stress incontinence. MATERIALS AND METHODS: Records of 115 women underwent anti-incontinence procedure using Ophira Mini Sling from June 2019 to September 2020 reviewed. Subjective evaluation was assessed using validated IIQ-7, UDI-6, POPDI-6 and PISQ-12 questionnaires. Multichannel urodynamics, 1-h pad test and 72-h voiding diary was performed as objective evaluation. Primary outcome was the objective cure rate of negative urine leak on provocative filling cystometry and 1-h pad test weight <2 g, and subjective cure rate was negative response to question 3 of UDI-6. Secondary outcome was to identify risk factors associated with failure for Ophira. RESULTS: Total of 108 women were evaluated. The objective cure rate was 91.7% with subjective cure rate of 86.1%. Comparison of clinical outcome shows significant improvement of USI post-operatively (p < 0.001) and reflected in 1-h pad test (p < 0.001). Improvement in all subjective evaluation parameters is seen except for POPDI-6. Failure of Ophira correlate significantly in women age >66 years, presence of asthma, pre-operative Intrinsic Sphincter Deficiency (ISD), and Maximum Urethral Closure Pressure (MUCP) value < 40 cmH20. CONCLUSION: Ophira Single Incision Mini Sling is safe and effective treatment option for USI, showing high objective and subjective cure rates with low incidence of complications. Non-modifiable risks of age ≥66 years, asthma status, pre-operative intrinsic sphincteric deficiency and low maximal urethral closure pressure were the factors of failure for Ophira.

What maximal urethral closure pressure threshold predicts failure of mid-urethral sling surgery?

OBJECTIVE: Low Maximal Urethral Closure Pressure (MUCP) is linked to unfavourable outcome of anti-incontinence surgery, however the cut-off value varied within studies. This study aimed to predict the cut-off value of MUCP that contributes to poor outcome of Mid-Urethral Sling (MUS) surgery in Urinary Stress Incontinence (USI) patients. MATERIALS AND METHODS: Records of 729 women underwent MUS procedure from January 2004 to April 2017 reviewed. Patients were divided into four MUCP groups, which were <20 cmH2O (≥20 and < 40) cmH2O (≥40 and ≤ 60) cmH2O and >60 cmH2O. Objective evaluation comprising 72-h voiding diary, multichannel urodynamic study (UDS) and post-operative bladder neck angle measurement. Subjective evaluation through validated urinary symptoms questionnaires. Primary outcome was objective cure rate of negative urine leak on provocative filling cystometry and 1-h pad test weight <2 g, and subjective cure rate was negative response to question 3 of UDI-6. Secondary outcome was identifying risk factors of cure failure for MUS in low MUCP groups. To identify the risk factors of cure failure, MUCP groups were narrowed down into <40 cmH2O or ≥40 cmH2O. RESULTS: Total of 688 women evaluated. Overall objective cure rate was 88.2% with subjective cure rate of 85.9%. Objective and subjective cure rates were lower in groups with low MUCP <40 cmH2O. Failure of MUS correlate significantly in patients with low MUCP <40 cmH20, bladder neck angle <30° and Functional urethral length (FUL) < 2 cm. CONCLUSION: Women with MUCP <40cmH2O, bladder neck angle <30° and FUL < 2 cm are more likely to have unfavorable outcome following MUS surgery. We proposed the cut-off low MUCP <40cmH2O as predictor for fail MUS surgery in SUI patients.

In Vitro and In Vivo Drug Release from a Nano-Hydroxyapatite Reinforced Resorbable Nanofibrous Scaffold for Treating Female Pelvic Organ Prolapse.

Pelvic prolapse stands as a substantial medical concern, notably impacting a significant segment of the population, predominantly women. This condition, characterized by the descent of pelvic organs, such as the uterus, bladder, or rectum, from their normal positions, can lead to a range of distressing symptoms, including pelvic pressure, urinary incontinence, and discomfort during intercourse. Clinical challenges abound in the treatment landscape of pelvic prolapse, stemming from its multifactorial etiology and the diverse array of symptoms experienced by affected individuals. Current treatment options, while offering relief to some extent, often fall short in addressing the full spectrum of symptoms and may pose risks of complications or recurrence. Consequently, there exists a palpable need for innovative solutions that can provide more effective, durable, and patient-tailored interventions for pelvic prolapse. We manufactured an integrated polycaprolactone (PCL) mesh, reinforced with nano-hydroxyapatite (nHA), along with drug-eluting poly(lactic-co-glycolic acid) (PLGA) nanofibers for a prolapse scaffold. This aims to offer a promising avenue for enhanced treatment outcomes and improved quality of life for individuals grappling with pelvic prolapse. Solution extrusion additive manufacturing and electrospinning methods were utilized to prepare the nHA filled PCL mesh and drug-incorporated PLGA nanofibers, respectively. The pharmaceuticals employed included metronidazole, ketorolac, bleomycin, and estrone. Properties of fabricated resorbable scaffolds were assessed. The in vitro release characteristics of various pharmaceuticals from the meshes/nanofibers were evaluated. Furthermore, the in vivo drug elution pattern was also estimated on a rat model. The empirical data show that nHA reinforced PCL mesh exhibited superior mechanical strength to virgin PCL mesh. Electrospun resorbable nanofibers possessed diameters ranging from 85 to 540 nm, and released effective metronidazole, ketorolac, bleomycin, and estradiol, respectively, for 9, 30, 3, and over 30 days in vitro. Further, the mesh/nanofiber scaffolds also liberated high drug levels at the target site for more than 28 days in vivo, while the drug concentrations in blood remained low. This discovery suggests that resorbable scaffold can serve as a viable option for treating female pelvic organ prolapse.

The properties of absorbable scaffold harvested with human amniotic fluid stem cells on rat model: an innovation for pelvic reconstruction surgery.

The current practice of restoring the anatomical structure in the treatment of pelvic floor dysfunction includes implantation of synthetic sling, which carries potential complications. This study aimed to develop biological substitutes to improve tissue function using scaffolds as a support to the host cells, through formation of new tissue. Human amniotic fluid stem cells (hAFSCs) were seeded on synthetic mesh-scaffold of AlloDerm Regenerative Tissue Matrix (RTM), Poly-DL-lactico-glycolic acid (PLGA) mesh (VICRYL) and Polydioxanone (PDS) meshes. In vitro study evaluates the metabolic activity of hAFSCs seeded mesh-scaffolds. In vivo study involving Sprague-Dawley rats was performed by assigning into 7 groups of sham control with fascia operation, AlloDerm implant, PDS implant, PLGA implant, AlloDerm harvest with hAFSC (AlloDerm-SC), PDS harvest with hAFSC(PDS-SC) and PLGS harvest with hAFSC (PGLA-SC). In vitro study reveals cell viability and proliferation of hAFSC on mesh scaffolds varies between meshes, with AlloDerm growing the fastest. The biomechanical properties of tissue-mesh-complex tension strength declined over time, showing highest tension strength on week-1, deteriorated similar to control group on week-12. All hAFSC-seeded mesh provides higher tension strength, compared to without. This study shed the potential of synthetic mesh as a scaffold for hAFSC for the surgical treatment of pelvic floor dysfunction.

Outcomes of bladder outlet obstruction following extensive vaginal pelvic reconstruction surgery on patient with advanced pelvic organ prolapse.

OBJECTIVE: To evaluate the impact of extensive vaginal pelvic reconstruction surgery (PRS) on advanced pelvic organ prolapse (POP) patients with bladder outlet obstruction (BOO). METHODS: We conducted a single-center, retrospective analysis of women who received extensive vaginal pelvic reconstruction surgery for advanced POP (POP-Q ≥3) with BOO from January 2006 to January 2016. Data regarding preoperative evaluation, surgical procedure, and postoperative management were abstracted from medical records. Patients were considered to have BOO when detrusor pressure at maximum flow (Dmax) was ≥20 cm H2O and peak flow rate (Qmax) was ≤15 mL/s. Patients with postoperative value of Dmax lower than 20 cm H2O or Qmax higher than 15 mL/s were regarded as objectively cured. RESULTS: A total of 1894 patients with POP stages III or IV were assessed. The incidence of BOO was 22.8% (431/1894) within this patient population of advanced POP. One year after the vaginal PRS, the objective cure rate of BOO was 98.1%. Urodynamic parameters showed a significant increase in Qmax (P < 0.001), while Dmax (P < 0.001) and postvoid residual urine (PVR) (P < 0.001) were significantly decreased. Previous POP surgery, native tissue repair (NTR), PVR ≥200 mL, and maximal cystometric capacity (MCC) ≥500 mL increase the likelihood of persistent BOO in patients. CONCLUSION: Vaginal PRS demonstrated effectiveness in treating BOO in patients with advanced POP. Irrespective of the types of transvaginal mesh (TVM), using TVM achieved better outcome than did NTR. Previous POP surgery, preoperative PVR ≥200 mL, and MCC ≥500 mL were the risk factors predicting the failure of PRS in improving BOO.

A Roadmap for Training in Urogynecology: IUGA International Initiative.

INTRODUCTION AND HYPOTHESIS: Training in urogynecology is an important mission of the International Urogynecological Association (IUGA). Promoting official training programs in countries around the world is an integral part of this mission. METHODS: The IUGA established the Fellowship Development Committee to develop a roadmap to assist countries to develop a professional training program in urogynecology. Two focus groups were created: the curricula topics focus group and the survey focus group. The curricula topics focus group is aimed at developing a list of subjects that can be the basis for a training syllabus. The survey focus group is aimed at understanding the main steps and the difficulties in establishing an official training program by interviewing representatives from both accredited and non-accredited countries and developing a roadmap for an official training program recognized by the local authorities. RESULTS: The fellowship development committee included 13 members. The curricula topics focus group developed a format for the description of each included topic. Each topic had to include a description of the required related skills and procedures. Two curricula topics lists were created: one for basic training and a second for advanced training. The survey focus group conducted two table discussions with representatives from countries with accredited training programs and countries without accredited training programs. The comments of these meetings were summarized in documents submitted to the IUGA board of directors. CONCLUSION: The fellowship development committee studied the main hurdles to developing an official training program in urogynecology. The roadmap document should form the basis of the IUGA international initiative to assist countries around the world to develop an official training program in urogynecology recognized by the local authority.

Anterior-apical Transvaginal Mesh (Calistar-S) for Treatment of Advanced Urogenital Prolapse: Surgical and Functional Outcomes at 1 Year.

INTRODUCTION AND HYPOTHESIS: Calistar-S is a single-incision synthetic mesh kit that addresses apical and anterior compartment prolapse. The aims of this study were to evaluate the short-term objective and subjective outcomes at the 1-year follow-up. The secondary objectives were to evaluate quality of life and lower urinary tract symptoms (LUTS) outcomes, as well as surgical complications. METHODS: Records of 108 patients with symptomatic advanced pelvic organ prolapse (stages III and IV) who underwent prolapse surgery using the Calistar-S system from June 2018 to August 2022 were reviewed. The primary outcome was the objective cure of anterior and apical prolapse < stage 1, and the subjective cure was the negative response to questions 2 and 3 of the Pelvic Organ Prolapse Distress Inventory-6. Secondary outcomes measured quality of life, the presence of lower urinary tract symptoms, and complications. RESULTS: A total of 101 patients were evaluated. The overall objective cure rate is 97% and the subjective cure rate is 92.1%. Good outcomes were seen in all three compartments. Secondary outcomes show significant improvement in all validated questionnaires. Persistence and de novo urinary incontinence were 15.2% and 18.2% post-operatively. There is one case of bladder injury and one case of vaginal mesh exposure. CONCLUSIONS: The Calistar-S System is a safe and efficient method for treating advanced-stage POP. We observed good anatomical results and subjective relief with a minimal complication rate. LUTS have also been positively affected, showing a high success rate. Additional studies are needed to establish the long-term efficacy of this system.

Voiding Dysfunction in Patients With Advanced Pelvic Organ Prolapse and Bladder Outlet Obstruction Following Pelvic Reconstructive Surgery: Urodynamic Profile and Predictive Risk Factors.

STUDY OBJECTIVE: To determine the outcome of voiding function 1 year after pelvic reconstructive surgery (PRS) in women with bladder outlet obstruction (BOO). DESIGN: Retrospective cohort study. SETTING: Tertiary referral hospital. PATIENTS: A total of 1894 women underwent PRS for advanced pelvic organ prolapse (POP) stages 3 to 4 with urodynamic findings of BOO. INTERVENTIONS: PRS. MEASUREMENTS: The primary outcome measured was the resumption of normal voiding function, defined clinically with multichannel urodynamic testing at 1 year postoperatively. The secondary outcomes were to identify the different risk factors for persistence voiding dysfunction (VD) 1 year after PRS. MAIN RESULTS: A total of 431 women with Pelvic Organ Prolapse Quantification stages 3 and 4, urodynamic study of maximum urinary flow rate ≤15 mL/s, and detrusor pressure at maximum flow ≥20 cm H2O were included. Resumption of normal voiding function was found in 91% (n = 392 of 431), whereas 9% (n = 39 of 431) remained to have VD 1 year postoperatively. Those with persistent VD, 20.5% (n = 8 of 39) remained having urodynamic diagnosis of BOO. Univariate and multivariate logistic regression revealed factors associated with postoperative VD were pre-operative maximal cystometric capacity ≥500 mL and postvoid residual volume ≥200 mL. CONCLUSION: VD may persist in women with BOO after PRS, particularly in those with preoperative maximal cystometric capacity of >500 mL and postvoid residual volume >200 mL.

Polypropylene anterior-apical single-incision UPHOLD-LITE mesh surgery in women with severe pelvic organ prolapse: Outcome at 53 months follow up.

BACKGROUND AND PURPOSE: We present this current study to complement with mesh inlays plausible benefits (UPHOLD-LITE System) on available long-term study amidst FDA's concern on mesh complications. This study aims to assess the medium-term outcomes of UPHOLD-LITE system for treatment of advanced pelvic organ prolapse (POP) and its complications, and lower urinary tract symptoms. METHODS: This is a retrospective case series of 53 months follow-up of 123 consecutive patients who underwent UPHOLD-LITE system. Objective outcome measures the anatomical correction of prolapse with POP-Q ≤ Stage 1. Subjective outcome was patient's feedback to questions 2 and 3 of POPDI-6. Secondary outcome measures the quality of life, presence of lower urinary tract symptoms and complications. Quality of life is assessed by validated questionnaires on Urogenital Distress Inventory 6 (UDI-6), Incontinence Impact Questionnaire 7 (IIQ-7), Pelvic Organ Prolapse Distress Inventory 6 (POPDI-6), and Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire 12 (PISQ-12) at 1 and 3 years post-operatively. RESULTS: Objective outcome at 1 and 3 years was at 96.7 % and 95.4 % respectively. The subjective cure was 95.1 % and 91.6 %. Five-year cumulative cure rate maintained at 87.2 %. Secondary outcomes observed improvement on UDI-6, IIQ-7, POPDI-6 and PISQ-12 postoperatively. Bladder outlet obstruction improved while de novo urodynamic stress incontinence (USI) increased slightly post surgically. Mesh erosion rate was 0.8 %. CONCLUSION: The UPHOLD-LITE system demonstrated good medium term anatomical correction of apical and anterior prolapse, with good subjective cure and improved quality of life. Whilst complication rate was low, slight increase in de novo USI was observed.

Urinary beta 3-adrenoceptor as a diagnostic biomarker for overactive bladder in women.

This study was to investigate urinary beta 3-adrenoceptor concentration as a biomarker for overactive bladder (OAB) and predictor of treatment outcomes in women receiving the beta 3-adrenoceptor agonist mirabegron. The study comprised 50 women identified with OAB and 35 women considered as healthy controls. All women with OAB received daily dosage of 50 mg of mirabegron for 12 weeks. Bladder diaries, OAB-related questionnaires, and global response assessment scale (GRAS) data were collected. Urinary beta 3-adrenoceptor concentration was measured through enzyme-linked immunosorbent assay. All OAB-related questionnaires and GRAS indicated improved posttreatment urinary health. After mirabegron treatment, the frequency of micturition and urgency episodes decreased, but the urinary beta 3-adrenoceptor/creatinine (Cr) ratio increased. The urinary beta 3-adrenoceptor/creatinine ratio was identified as a sensitive biomarker for OAB with a confidence interval of 0.656 to 0.856 (p < 0.001). A negative correlation (- 0.431, p = 0.040) between this biomarker and health-related quality of life (HRQL) scores. The Beta 3-adrenoceptor/Cr levels increased significantly in the treatment-responsive group, while they remained unchanged in the unsatisfactory outcome group. This study shows that 12 weeks of mirabegron treatment improves OAB symptoms and HRQL. Furthermore, urinary beta 3-adrenoceptor concentration may be a diagnostic biomarker for OAB.

A time-frame comparison study of surgical volume shifts on female primary stress urinary incontinence surgery.

INTRODUCTION AND HYPOTHESIS: The objective was to investigate the surgical volume shifts for primary female stress urinary incontinence (SUI) over a 20-year period (1999-2018) in Taiwan. METHODS: This was a retrospective cohort study based on Taiwan's National Health Insurance Research Database. We divided the time-frame into four periods: first period (1999-2003), second period (2004-2008), third period (2009-2013), and fourth period (2014-2018). The variables included major surgical types for SUI (retropubic urethropexy, pubovaginal sling, midurethral sling, etc.), surgeon gender, specialty, surgical volume (high ≥30, median 5-29, low <5), and hospital accreditation level. Reoperation rates within 1 year were analyzed as an outcome measurement. RESULTS: A total of 51,018 patients were identified. Major surgical types increased significantly during the first three periods and slightly decreased during the fourth period. The proportion of surgical volume shifted from high- to medium-, and low-volume, but it reversed during the fourth period. The proportion of SUI surgeries decreased in medical centers, whereas it increased in regional and local hospitals. The proportion of SUI surgeries by female surgeons increased. Similar phenomena occurred in MUS. As for surgeon specialty, major surgical types were performed by gynecologists and urologists equally, whereas MUS were performed more by gynecologists than by urologists. Unexpectedly, 1-year reoperation rates were higher in high-volume surgeons. CONCLUSIONS: The surgical trend of SUI surgeries shifted from high- to medium-, and low-volume surgeons, medical centers to regional and local hospitals during the study periods. This implied surgical skills and performance spreading, which may have a great influence on patient and healthcare provider choice of treatment.

Use of low-intensity extracorporeal shock wave therapy in the management of interstitial cystitis/bladder pain syndrome patients: A thirty case study in a tertiary medical center.

INTRODUCTION: Low-energy extracorporeal shock wave therapy (LiESWT) is a new potential treatment for intractable interstitial cystitis/bladder pain syndrome (IC/BPS), and this paper will evaluate its therapeutic effects on IC/BPS. MATERIALS AND METHODS: This prospective clinical trial enrolled 30 women who have been diagnosed with IC/PBS to receive LiESWT treatment at an intensity of 0.25 mJ/mm2 and a frequency of 3 pulses/second, for a total of 3000 pulses within 8 weeks. And we assessed questionnaires (including O'Leary-Sant Interstitial Cystitis Symptom Index (ICSI)), 3-day voiding diary, and urodynamic study at the following intervals: 4 weeks of LiESWT (W4), 8 weeks of LiESWT (W8), 1-month follow-up (F1), 3-month follow-up (F3) after LiESWT, and 1 year follow-up (F12). RESULTS: The primary outcome of questionnaires showed significant improvement of symptoms compared to baseline (W0), especially on ICSI(12.87 ± 3.44 before treatment and 7.87 ± 5.27 at F12, p < 0.05). 3-day voiding diary also revealed significant decrease in daytime voiding frequency (15.57 ± 5.22 times before treatment and 10.70 ± 4.21 times at F1, p < 0.05) and significant increase on average voiding volume (95.85 ± 35.30 mL before treatment and 161.27 ± 74.21 mL at F1, p < 0.05). However, there were no significant differences in all parameters of the urodynamic study. CONCLUSION: LiESWT can mitigate pain and lower urinary tract symptoms and improve the quality of life in IC/PBS patients, but does not increase the maximal cystometric capacity.

Correlation between overactive bladder and detrusor overactivity: a retrospective study.

INTRODUCTION: The primary objective of this study is to determine the prevalence of overactive bladder (OAB) and detrusor overactivity (DO) in female patients who were referred for urodynamic study (UDS) because of lower urinary tract symptoms (LUTS). The secondary objective is to determine the subjective and objective differences between female OAB patients with and without DO. MATERIALS AND METHODS: All female patients who underwent UDS for LUTS between June 2016 and September 2019 were retrospectively reviewed. Personal history, medical history, physical examination, and validated questionnaires were collected. One-hour pad test and multichannel urodynamic study was performed. All statistical analyses were conducted by SAS 9.4. P-value < 0.05 was considered statistically significant. RESULTS: A total of 4184 female patients underwent UDS because of LUTS between June 2016 and September 2019; 1524 patients were analyzed for OAB or DO. The occurrence of OAB was 36.4%. The overall incidence of DO in OAB patients was 15.5%; 9.5% of all patients had DO findings on UDS, and 4.6% were incidental findings. There were significant differences among mean age, parity, ICIQ-UI SF, OABSS, POPDI-6, and all UDS parameters (except for maximal urethral pressure and pressure transmission ratio) between patients with and without DO. In patients with DO, there were no significant differences among age, parity, and BMI with or without OAB symptoms. However, there were significant differences among mean OABSS, ICIQ-UI SF, UDI-6, POPDI-6, IIQ-7, and pad test. CONCLUSIONS: Patients with DO are associated with older age, increased parity, greater urine leakage, and worse storage and micturition functions on UDS. Combinations of subjective and objective measurements are better predictive models for OAB patients.

Combing pre-workshop, web-based learning and hands-on workshop as a flipped classroom clinical skill training model during the COVID-19 pandemic.

OBJECTIVE: Due to the COVID-19 pandemic, there is a dramatic drop in in-person residency training due to the implementation of isolation and triage measurements. Here, we propose a new flipped classroom clinical skill training model utilizing a combination of pre-workshop, web-based learning and hands-on workshop that shortens in-person contact time to maintain residency training during the pandemic. Effectiveness of this training model was evaluated with a pre-test and post-test skills competency assessment, two-way feedback, and a five-point Likert scale structured survey questionnaire. MATERIALS AND METHODS: The workshop was conducted in a flipped classroom fashion by the obstetrics and gynecology (OBGYN) department of a single tertiary teaching medical center covering topics from five OBGYN subspecialities. Every topic consisted of a pre-workshop, web-based, mini lecture (PWML) followed by a hands-on workshop (HW). All first to fourth year OBGYN residents were invited to attend the workshop. All the trainees were required to complete the PWML prior to the day of HW. The workshop consisted of rotational station for each topic and was conducted within one afternoon. A 0-100-point scale pre-test and post-test skills competency evaluation were performed for each station and was assessed by the attending doctor or fellow doctor of each subspeciality. Two-way feedback was done after the post-test evaluation. A five-point Likert scale structured survey instrument consisting of participant's perceptions of the workshop design, relevance to clinical practice, and quality of instructors and materials was created during the curriculum development process and sent to each participant one month after the workshop. RESULTS: A total of 19 residents including five first-year, six second-year, three third-year, and five fourth-year residents completed the entire pre-workshop lecture, workshop, pre-test, and post-test. For all residents, the average post-test score of 5 stations was 95 and was significantly higher than the pre-test score of 60 (p < 0.001). For both junior residents and senior residents, the average post-test scores of 5 stations were also significantly higher than pre-test scores (p < 0.001). Survey generated one month after the workshop showed a high overall satisfaction with the workshop instructors on their professional knowledge, communication skills, and interactions between the instructors and trainees. The average satisfaction scores for manipulation of vaginal breech delivery (VBD), semen analysis (SA), cervical conization (CC), obstetrics anal sphincter injury (OASIS), and laparoscopic suture techniques (LST) were 4.84, 4.96, 4.92, 4.88, and 4.92, respectively The average score for practical application of the training materials, class design and teaching method, overall satisfaction of the session, and time scheduling was 4.84, 4.96, 4.96, and 4.48, respectively. The entire HW was completed within 180 min and was carried out within half a day. CONCLUSION: With the implementation of isolation and triage measures in the COVID-19 pandemic, there is a dramatic drop in in-person exposure to all aspects of the residency training, in particular, non-emergent surgeries. Utilization of PWML saved 1/3 of in-person time and the entire workshop was completed within 180 min that could be carried out within half a day. The decrease of person-to-person contact time during the COVID-19 pandemic is necessary while still providing curriculum-based residency training in spite of decreased hands-on experience.

Ultrasonography and clinical outcomes following anti-incontinence procedures (Solyx™ tape): a 3-year post-operative review.

INTRODUCTION AND HYPOTHESIS: Our primary objective was to study objective and subjective outcomes of patients with urodynamic stress incontinence (USI) following Solyx™ at 3-year follow-up. Our secondary objective was to evaluate ultrasonographic tape and bladder neck position and mobility. METHODS: Records of 88 women who received Solyx™ surgery between September 2015 and December 2017 were reviewed. Ultrasonographic sling evaluation was performed at 6 months and 3 years postoperatively. Primary outcomes were objective and subjective cure of stress incontinence, defined as no involuntary urine leakage during filling cystometry, 1-h pad test < 2 g and negative response to Urogenital Distress Inventory-6 Question 3. RESULTS: Subjective and objective cure rates at 3 years were 85.2% and 87.5%, respectively, with no complications reported. QOL improvements were maintained. Bladder neck position and mobility had no significant change between 6-month and 3-year follow-up. Tape position demonstrated significant shifts in the y-axis at both rest and Valsalva and in the x-axis at Valsalva between 6 months and 3 years; overall mobility was unchanged. Percentile of sling location remained unchanged at 60.1%, as did percentage of urethral kinking (67.9%) achieved. Risk factors for failure were bladder neck hypomobility postoperatively and no urethral kinking postoperatively. CONCLUSIONS: There was good sustained objective and subjective cure with improved QOL in women who underwent Solyx™ for USI at 3-year follow-up. Ultrasonographic evaluation showed a tape position shift upwards and backwards with unchanged tape and bladder neck mobility. Percentile of sling location and rates of dynamic kinking were maintained.

Impact of intrinsic sphincter deficiency on mid-urethral sling outcomes.

INTRODUCTION AND HYPOTHESIS: Our primary objective was to study outcomes of patients with intrinsic sphincter deficiency (ISD) following mid-urethral slings (MUS) at 1-year. Our secondary objective was to delineate factors affecting success in these patients. METHODS: Six hundred eighty-eight patients who had MUS between January 2004 and April 2017 were reviewed retrospectively; 48 women were preoperatively diagnosed with ISD. All completed urodynamic studies and validated quality-of-life (QOL) questionnaires at baseline and 1 year. Primary outcomes were objective and subjective cure of stress incontinence, defined as no involuntary urine leakage during filling cystometry and 1-h pad test < 2 g and negative response to Urogenital Distress Inventory-6 Question 3. Ultrasound was performed to determine tape position, urethral mobility and kinking at 1 year. RESULTS: Women with ISD had significantly lower objective and subjective cure rates of 52.1% and 47.9%, respectively, compared to an overall of 88.2% and 85.9%. QOL scores significantly improved in those with successful surgeries. The sling type did not make a difference. Multivariate logistic regression identified reduced urethral mobility [OR 2.11 (1.24-3.75)], lower maximum urethral closure pressure (MUCP) [OR 1.61 (1.05-3.41)] and tape position [OR 3.12 (1.41-8.71)] to be associated with higher odds of failed slings for women with ISD. CONCLUSIONS: Although there are good overall success in women undergoing MUS, those with ISD have significantly lower cure rates at 1 year. Factors related to failure include reduced urethral mobility, low MUCP and relative tape position further away from the bladder neck. Optimal management of patients with ISD and reduced urethral mobility remains challenging.

Immunochemical and urodynamic outcomes after polypropylene mesh explant from the pelvic wall of rats.

INTRODUCTION AND HYPOTHESIS: To analyze the immunochemical and urodynamic outcomes after partial versus complete excision of transvaginal polypropylene mesh (PPM) from pelvic walls of rats. METHODS: Forty-eight female Sprague-Dawley (SD) rats were randomly distributed into seven groups: control, mesh total removal 60 days (M-T 60D), mesh total removal 180 days (M-T 180D), mesh partial removal 60 days (M-H 60D), mesh partial removal 180 days (M-H 180D), sham 60 days (Sham 60D), and sham 180 days (Sham 180D). In the mesh groups, PPM was inserted and partially (0.3 × 0.3 cm) or completely removed 30 days later. In the Sham group, the space between the vagina and bladder was dissected without placing or removing the synthetic mesh at day 1 and day 30 later. Urodynamic studies, immunochemical analysis, and Western blot were done at days 60 and 180. RESULTS: The M-T 60D voiding pressure was significantly decreased compared to the Sham 60D and M-H 60D. The voiding interval of M-T 60D was significantly shorter than that of M-H 60D. In the M-T 60D and M-T 180D groups, the leak point pressure was significantly less than in their corresponding sham groups. IL-1 and TNF-α were significantly more intense in M-T 60D compared to M-H 60D and Sham 60D. NGF was significantly greater in M-T 60D compared to Sham 60D. There were no significant differences in MMP-2 and CD-31s throughout the group. CONCLUSION: Total mesh excision incites a host inflammatory response and transitory lower urinary tract dysfunction. Despite the good outcomes after total excision, the invasiveness and surgical risk associated with repeated procedures should not be underestimateded.
