Babcock versus Scissor Tensioning for Retropubic Mid-Urethral Slings: Comparing Two Intra-Operative Techniques Through 5 Years of Follow-Up.

INTRODUCTION AND HYPOTHESIS: The objective was to determine if mid-urethral sling (MUS) tensioning with a Mayo Scissor as a sub-urethral spacer compared with a Babcock clamp holding a loop of tape under the urethra results in differences in patient-reported outcomes and rates of repeat surgery over a 5-year follow-up. METHODS: Follow-up 5 years after a randomized clinical trial, utilizing primary data collection linked to administrative health data, was carried out to create a longitudinal cohort. The primary outcome was participant-reported bothersome SUI symptoms, as defined by the Urogenital Distress Inventory (UDI-6) questionnaire. Secondary outcomes included participant-reported bothersome overactive bladder (OAB) scores, median scores of three validated urinary symptom questionnaires, and rates of subsequent surgery determined through patient report and administrative data. RESULTS: Two hundred and sixty (81.8%) of the original study participants provided participant-reported data at 5 years. Administrative data linkage was completed for all of the original participants (n = 318). Demographic characteristics remained similar in the two groups at the 5-year follow-up mark. No differences existed in the primary outcome of reported bothersome SUI symptoms (30.8% Scissors vs 26.8% Babcock, p = 0.559), proportion of participants with bothersome OAB, the median scores of three validated bladder questionnaires, or in rates and cumulative incidence of recurrent MUS surgery or surgical revision of mesh-related complications. CONCLUSION: Both the Scissor and Babcock tensioning techniques provided comparable outcomes at 5 years post-MUS surgery. The information from this study allows surgeons to better decide which technique to adopt in their practice, providing confidence in longer-term cure and safety.

The retrotracheal left pulmonary artery: A rare vascular malformation.

The retrotracheal left pulmonary artery, also known as "left pulmonary artery sling," is a rare vascular malformation in which the left pulmonary artery (LPA) arises from the posterior aspect of the right pulmonary artery (RPA) and reaches the left pulmonary hilum by passing between the trachea and the esophagus, giving rise to the appearance of a sling, hence the name "sling." This vascular anomaly can be associated with other cardiac malformations or abnormalities of the tracheobronchial tree.We present the case of a 4-month-old female infant who presented with laryngeal stridor. She underwent a chest X-ray, which was normal, but thoracic CT angiography revealed an aberrant LPA originating from RPA with a retrotracheal course. This case underscores the critical role of imaging in confirming the diagnosis and guiding patient management.

Supporting the Choice for Conservative and Surgical Treatment in Female Stress Urinary Incontinence: Development and Evaluation of a Patient Decision Aid.

INTRODUCTION: Making a treatment decision for female stress urinary incontinence (SUI) can be challenging for patients and healthcare providers. Dutch guidelines advise to counsel both pelvic floor muscle therapy and midurethral sling surgery as primary treatment options in uncomplicated moderate to severe cases. The use of a patient decision aid (PDA) can support decision-making, reduce decisional conflict and decisional regret, and increase knowledge. The aim of this study was to develop and evaluate an online PDA for females (SUI). METHODS: This mixed-methods study was performed in consecutive stages by a multidisciplinary working group. PDA design was based on the International Patient Decision Aids Standards (IPDAS) and on outcomes of needs assessments amongst patients and healthcare providers. Content was based on Dutch guidelines, targeted literature searches and patient information from the Dutch scientific society for gynecology. The concept version was evaluated by patients, patients' advocates, and healthcare providers. RESULTS: Using the nominal group technique, the working group established the design and format of the PDA. Fifty-six out of 58 applicable items of the IPDAS were met. The PDA contains information on the condition, advice on lifestyle adaptations, and describes surgical and nonsurgical treatment options. The option grid contains comparisons of the primary treatment options. Furthermore, value clarification exercises and narratives were included. Acceptability and usability evaluation of the concept version was performed by 15 healthcare providers, three patients, and two patients' advocates. Comments were processed in the working group, resulting in the final version of the PDA, which was supported by all assessors. CONCLUSION: Our multidisciplinary working group developed an online PDA for women with moderate to severe SUI including conservative and surgical treatment options, based on IPDAS criteria, guidelines, scientific evidence, and needs assessments from patients and healthcare providers. This PDA is supported by patients, healthcare providers, scientific societies, and the Dutch patients' association. The next step is to evaluate and implement this PDA in daily practice.

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.

The male slings: an effective and safe alternative surgical treatment to the artificial urinary sphincter for male stress urinary incontinence?-a narrative review.

Background and Objective: The ideal candidate for a male sling (MS) should have a mild to moderate degree of stress urinary incontinence (SUI). This narrative review article evaluates the current MS devices in the commercial market and examines the role of MS as an effective and safe alternative treatment option for male SUI. Methods: The available literature on MS was reviewed and relevant clinical studies pertaining to each MS were summarised with emphasis on device design and technology as well as specific surgical findings relating to clinical outcomes. Key Content and Findings: Over the past two decades, there have been considerable scientific advances in MS design and technology, and MS is an attractive alternative for patients who might not require or want an artificial urinary sphincter. The modern MS can be classified as adjustable or non-adjustable types and is placed either through a retropubic or transobturator (TO) approach. Strict patient selection and counselling, selection of MS with proven clinical records, and safe surgical practice are paramount to ensure a high continence rate, good patient satisfaction, and low postoperative complications. Published data on various MS materials and devices showed reasonable clinical efficacy and safety outcomes, although many of these synthetic MS devices may not be available worldwide due to a lack of regulatory approval in many countries. While the ideal MS is probably yet to be developed, continued scientific advances in slings design, mesh technology, and more refined surgical techniques will improve the continence rate and deliver better safety records. Conclusions: As clinical data matures with longer-term outcomes coupled with advances in scientific designs and technology, the ability to have and select the optimal MS for a particular patient will come to fruition.

Male sling versus artificial urinary sphincter for the treatment of incontinence after prostate surgery: a systematic review with meta-analysis.

Background: Urinary incontinence following prostate treatment (IPT) represents a significant complication that detrimentally impacts the quality of life for patients who have undergone prostate surgery. Presently, there is a scarcity of evidence regarding the preferred surgical techniques for IPT. We conducted a meta-analysis to compare the outcomes of the male sling and artificial urinary sphincter (AUS) in the treatment of IPT. Methods: Data were extracted through electronic literature searches on PubMed, Web of Science, and Embase databases until September 2023. Eligible studies included patients who underwent AUS or male sling procedures for IPT and had a follow-up duration exceeding 12 months. The primary end point was the success rate, with the secondary outcome focusing on complication rates. A fixed-effects or random-effects models were used to calculate the pooled estimate and its 95% confidence interval (CI). The publication bias was assessed using funnel plots and Egger's regression test. Results: The meta-analysis included nine studies, involving a total of 1,350 participants. No statistically significant difference in success rates was found between AUS and male sling [odds ratio (OR): 0.96, 95% CI: 0.91-1.01]. In terms of the complication rate, there was no significant disparity between the two procedures (OR: 0.87, 95% CI: 0.86-1.12). Conclusions: The findings from this study indicated that male sling surgery yielded success and complication rates comparable to those of AUS. This suggests that male sling could serve as a viable alternative surgical option in the treatment of IPT.

Conservative Treatment of an Isolated Greater Tuberosity Fracture With Dislocation: Management of Post-Traumatic Subacromial Impingement Syndrome and a Mini-Review of the Literature.

This case report evaluates the effectiveness of conservative treatment for an isolated greater tuberosity fracture-dislocation, detailing the treatment process and addressing post-traumatic subacromial impingement syndrome with a mini-review of the literature. A 26-year-old male fell from a height, resulting in a self-reduced dislocated shoulder. Examination revealed extensive ecchymosis, pain, and limited motion in the right shoulder. Radiological assessments showed an isolated greater tuberosity fracture, partial tears of the supraspinatus and subscapularis muscles, a suspected ALPSA lesion, and periarticular effusion. Initial treatment included a shoulder sling, passive elbow and wrist exercises, and pendulum exercises starting in the second week. At six weeks, persistent pain prompted TENS therapy and advanced rehabilitation exercises. At three months, the patient continued to experience pain and restricted shoulder movement. An MRI ruled out labral pathology, and a shoulder ultrasound revealed post-traumatic subacromial bursitis, leading to a diagnosis of subacromial impingement. A diagnostic ultrasound-guided injection of prilocaine into the subacromial bursa significantly improved the range of motion and alleviated pain within one hour. Treatment recommendations included avoiding overhead activities, NSAIDs, and continued rehabilitation. By six months, the patient had achieved a pain-free range of motion of 180 degrees. This case demonstrates that conservative treatment and appropriate rehabilitation can effectively manage isolated greater tuberosity fractures and associated glenohumeral joint dislocations. Early diagnosis and suitable rehabilitation strategies for post-traumatic subacromial impingement syndrome positively influenced the patient's recovery. Given the patient's youth and swimming background, steroid injections were avoided due to potential complications, with successful recovery achieved through NSAIDs, overhead activity restriction, and rehabilitation.

A novel lower eyelid reconstruction using a skin-tarsoligamentous sling to prevent postoperative drooping deformity: Quantitative analyses using drooping index and angular difference in canthal tilt.

Lower eyelid reconstruction using skin flaps sometimes results in undesirable deformities due to postoperative flap drooping. We aimed to examine the effectiveness of a novel procedure for reconstructing the skin-tarsoligamentous sling of the lower eyelid. We included 37 patients who underwent anterior lamellar reconstruction with a cheek rotation flap for full-thickness lower eyelid defect. They were divided into two groups: Group A included 19 patients who underwent tarsoligamentous sling reconstruction with a fascia lata strip and buccal mucosa grafting, and Group B comprised 18 patients who underwent skin-tarsoligamentous sling reconstruction using an additional combination of a periosteal flap and de-epithelialized triangular flap at the lateral canthal region, representing our novel approach. To evaluate the severity of postoperative deformities, we used the drooping index, the ratio of drooping compared to the healthy side, along with the angular difference in canthal tilt, obtained between the reconstructed and healthy sides, using photographs taken ≥6 months post-reconstruction. Group B demonstrated superior outcomes, with mean drooping indices of 1.13 compared to 1.33 in Group A (P = 0.031) and mean angular differences in canthal tilt of -0.73° compared to -2.45° in Group A (P = 0.021). Patient satisfaction was significantly higher in Group B than in Group A (P = 0.042). Furthermore, patients with drooping index <1.2 and an angular difference in canthal tilt ≥-1.0° exhibited higher satisfaction scores. Our novel approach to lower eyelid reconstruction using a skin-tarsoligamentous sling yielded improved aesthetic outcomes, fewer complications, and higher patient satisfaction.

Novel approaches facilitating neuraxial anesthesia placement in pregnant women with morbid obesity: case descriptions.

Clinical management of pregnant women with morbid obesity poses challenges in performing neuraxial anesthesia as well as positioning for cesarean delivery. Occupational injuries are also known to occur while caring for patients with morbid obesity. We describe two novel approaches to assist neuraxial anesthesia administration and positioning for cesarean delivery. With the assistance of the Institution's Safe Patient Handling and Mobility Team, a universal high-back sling can be placed to lift the patient into a sitting position before neuraxial anesthesia procedure. After placement of combined spinal epidural anesthesia, the ceiling lift is used to lift the patient into a seated position and then rotate to the appropriate location on the operating room table to facilitate supine positioning. The lifting system reduces shearing of the patient's posterior and compromising the epidural site. Team members also report reduced effort required when positioning patients from seated to supine on the operating room table. The second approach is the application of TraxiTM abdominal pannus retractor to retract fat folds encroaching on the epidural placement site in pregnant women with morbid obesity. This is particularly useful when the traditional taping of fat folds away from the site is inadequate. The pannus retractor results in a flatter surface facilitating epidural placement. We have introduced these two approaches into our clinical practice for pregnant women with morbid obesity requiring cesarean delivery under neuraxial anesthesia.

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.

Comparison of eyelid function following frontalis suspension and levator dissection-resection in congenital ptosis with poor levator function.

PURPOSE: A levator dissection-resection technique (LDR) in which the levator is dissected free from all fibrous attachments including Whitnall's ligament was compared to two commonly used frontalis-based procedures in the management of congenital ptosis with poor levator function. METHODS: Thirty patients having congenital ptosis with poor levator function were randomized to one of the three surgical groups (ten patients for each group), namely, frontalis sling (FS), frontalis advancement flap (FAF), and (LDR) technique. Marginal reflex distance-one (MRD-1), levator function, symmetry in different levels of vertical gaze, lagophthalmos, and any other surgical complications were assessed 6 months following the intervention. RESULTS: Patients in the three groups achieved statistically significant improvement in MRD-1 in the primary position of gaze (p = 0.001 for FS, 0.003 for FAF, 0.001 for LDR). Patients who underwent a frontalis-based procedure acquired an additional ability to elevate the upper eyelid by using their eyebrows. Patients who underwent LDR technique have acquired an additional mean of 5.79 ± 1 mm improvement in levator function with better symmetry during up and down gaze in unilateral cases. Patients from all groups had an equal degree of lagophthalmos with forced eyelid closure, and during sleep. CONCLUSION: Patients with ptosis and poor levator function who were managed with LDR technique achieved a similar degree of eyelid elevation in the primary gaze to that of frontalis-based procedures, acquired additional levator function, achieved more symmetry in up and down gaze in unilateral cases, and had no additional risk to the cornea.

Efficacy of botulinum toxin in the management of refractory de novo overactive bladder symptoms in women after midurethral sling placement: retrospective, single center study.

Introduction: This study aimed o evaluate the efficacy of onabotulinumtoxin A (onaBTX-A) intradetrusor injections in women with refractory de novo overactive bladder (OAB) following midurethral sling (MUS) placement. Material and methods: A retrospective single-center study was conducted. We screened 372 women who underwent MUS surgery between August 2009 and January 2022. 54/372 women diagnosed with pharmacologically refractory de novo OAB following MUS were evaluated using cystoscopy and urodynamics, and after tape erosion and obstructive voiding were excluded, they received onaBTX-A therapy. Outcomes were the reduction of self-reported OAB symptoms and leakage episodes, improvement of validated OAB scores and adverse events of the procedure after a follow-up of 3, 6, and 12 months. Results: Successful results were reported in 81%, 68%, and 43% at 3, 6 and 12 months respectively. Postoperatively, median voiding frequency and median nocturia episodes were significantly improved in 70% and 77% of women, respectively, with a decrease in daily number of voids (-4.1, p = 0.0001) and nocturia episodes (-2.2, p = 0.005). At 3 months, 80% of women reported an >25% reduction in urgency severity and episodes following injection. The median number of pads used was significantly reduced after injection (-2 pads; p = 0.03). Repeat injections of onaBTX-A were performed in 61% of patients after a median of 11 months. Conclusions: Intravesical onaBTX-A injections are clinically effective at 3- and 6-month follow-up for the treatment of refractory de novo OAB after MUS placement. Over 60% of the patients opted for retreatment with onaBTX-A due to a high level of satisfaction.

Comparison of Surgical Outcomes of Autologous Mid-Urethral Fascia Slings and Retropubic Mid-Urethral Slings for Women Undergoing a Primary Surgery for Stress Urinary Incontinence: A Systematic Review and Meta-Analysis.

AIM: Current guidelines on surgical treatment of stress urinary incontinence (SUI) recommend an informed decision making process between the physicians and patients reviewing all available surgical options with and without mesh. However, there is a lack of synthesized clinical evidence on some of the comparisons that can feed into patient counseling processes. The aim of this study was to review the available studies comparing clinical outcomes of an autologous fascial sling (AFS) and a retropubic (RP) synthetic sling for women undergoing a primary surgery for SUI. METHODS: We conducted a literature search from 1990 to 2024 following international guidelines. We have included studies reporting on comparative outcomes of AFS and RP synthetic sling surgeries as a primary procedure. RESULTS: Three randomized studies were included with follow-up durations ranging from 24 months to 10 years. The mean percentage change in symptom scores ranged from 27.7% to 44.9%, with no significant difference between the two sling types. There was no difference between groups with regard to objective cure rates, subjective cure rates and length of hospital stay between AFS and RP slings. AFS surgeries had longer operative times. There were concerns about bias, particularly related to allocation, blinding, and missing outcome data. CONCLUSION: Overall, both types of slings had similar cure rates but AFSs were associated with longer operative times. The study highlights the need for more research on the comparative effectiveness of AFS and synthetic slings for SUI surgery to guide decision-making for SUI surgical treatments.

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

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

Biomechanical comparison shows increased stability of an arthroscopic subscapular sling procedure compared to an open Latarjet reconstruction for anterior shoulder instability in specimens with major glenoid bone defect.

Purpose: Recurrent anterior glenohumeral instability (RASI) is commonly treated with arthroscopic techniques, though their effectiveness in providing stability may diminish in cases of critical glenoid bone loss. This study aimed to compare the stability outcomes and range of motion (ROM) associated with an arthroscopic subscapular sling procedure (SSP), first introduced in 2015. Methods: Sixteen fresh-frozen human cadaveric shoulder specimens were biomechanically evaluated in four conditions: native, injured, post-SSP and post-LP. Glenohumeral translations were measured under anterior, anteroinferior and inferior loading, while external rotation ROM was assessed in neutral and abducted positions. Testing was conducted using a robotic system for precise force and torque application. Specimens were prepared with a 20% glenoid bone defect and subjected to stability testing sequentially. Results: The SSP significantly reduced glenohumeral translations compared to LP, particularly under anterior loading in neutral (p < 0.001), external rotation (p = 0.007) and abduction (p < 0.001) positions. Although the SSP demonstrated superior stability in these key positions, it did not consistently outperform the LP across all scenarios, as stability was similar between the two in the abducted and rotated position under anterior loading (p = 0.379). Under anteroinferior loading, the SSP showed comparatively better stability at neutral (p = 0.003) and abduction (p < 0.001), whereas the LP led to greater anteroinferior translations in these same positions (p = 0.002 and p = 0.014, respectively). The SSP outperformed the LP under inferior loading in neutral (p = 0.005) and abduction (p = 0.02) positions, though it did not fully restore stability to native shoulder levels. The SSP maintained ROM similar to native shoulders. LP allowed greater ROM, potentially compromising stability. Conclusion: The SSP provided greater stability than the open Latarjet in most positions and did not limit ROM, suggesting it could be a viable, less invasive option for managing shoulder instability. Level of Evidence: Not applicable.

Tissue-engineered sub-urethral sling with muscle-derived cells for urethral sphincter regeneration in an animal model of stress urinary incontinence.

BACKGROUND: Stress urinary incontinence (SUI) is a widespread condition affecting more than 200 million people worldwide. Common treatments for this condition include retropubic colposuspension, and pelvic sling methods, which use autologous grafts or synthetic materials to support the bladder neck and urethral sphincter. Although these treatments have a cure rate of over 80%, adverse effects and recurrence may still occur. Several studies have focused on the potential of cell therapy. Muscle-derived cells (MDCs) can be easily obtained from small biopsied striated muscular tissues and possess superior multi-lineage differentiation and self-renewal capacity. METHODS: Based on the unique characteristics of MDCs and previous favorable results in muscle regeneration, we fabricated a chitosan-gelatin hydrogel sling loaded with MDCs in a rat model of SUI. Leak point pressure and histological indices regarding inflammation, muscular atrophy, and collagen density were assessed to compare the effectiveness of cell injection and cell-laden sling. RESULTS: The level of LPP was significantly reduced in the MODEL group versus the control animals. The LPP level was considerably higher in CELL INJECTION, SLING, and CELL/SLING groups compared to the MODEL group but did not reach the significance threshold. The inflammation rate was significantly lower in the CELL/SLING group compared to the SLING group. CONCLUSION: The CELL/SLING group showed less atrophy compared to the other experimental groups, indicating that the cells may have higher viability on SLING than through injection. This also suggests that in long-term studies, as the degradation rate of hydrogels increases, the function of cells will become more apparent.

Tracheoplasty should be proactively considered in the surgical strategy for treating the ring-sling complex.

OBJECTIVE: To examine the safety and effectiveness of proactive tracheoplasty for pediatric ring-sling complex. METHODS: We retrospectively collected data from 304 children who were diagnosed with a ring-sling complex and underwent surgery at 3 cardiac centers in China between January 2010 and June 2023. The children were categorized into 3 surgical groups: concurrent sling and tracheal surgery (group A; n = 258), staged sling and tracheal surgery (group B; n = 25), and sling-only surgery (group C; n = 21). We compared perioperative clinical characteristics, tracheal morphology changes, and outcomes across the 3 groups. RESULTS: The median age of the children was 1.2 years (interquartile range, [IQR], 0.7-1.9 years). The anomalous tracheobronchial arborization rates were higher in group A (52.5%) and group B (60.0%) compared to group C (15.0%). The preoperative narrow-wide ratio (NWR) was lower in groups A and B than in group C, with values of 0.44 (IQR, 0.35-0.52), 0.44 (IQR, 0.33-0.59), and 0.68 (IQR, 0.54-0.72), respectively (P < .001). Preoperative subcarina angles were similar among the groups (P = .54). After specific surgeries, the NWR and subcarina angle were improved significantly in groups A and B but not in group C. There were 7 in-hospital deaths and 2 postdischarge deaths. Respiratory symptoms improved in groups A and B, but 7 children in group C remained in respiratory dysfunction. Six children presented with residual stenosis of the left pulmonary artery. CONCLUSIONS: Concurrent sling and tracheal surgeries for children with the ring-sling complex are safe and effective and are especially preferable for those with NWR ≤0.6, long-segment or diffuse tracheal stenosis, anomalous tracheobronchial arborization, and pronounced respiratory symptoms.

Effects of Sling-Suspension-Based Active Shoulder Joint Exercise on Shoulder Joint Subluxation, Pain, Muscle Strength, and Upper Limb Function in Patients with Subacute Stroke.

Background and Objectives: We investigated the effects of sling-suspension-based active shoulder joint exercise training on shoulder joint subluxation, pain, muscle strength, and upper extremity function in patients with subacute stroke. Materials and Methods: Twenty-eight patients with subacute stroke were randomly assigned to either the sling-suspension-based active shoulder joint exercise (SASE) group (n = 14) or the motorized upper extremity exercise (MUEE) group (n = 14). The SASE group actively performed shoulder joint flexion, extension, abduction, adduction, external and internal rotation, and horizontal abduction and adduction using a sling suspension system, whereas the MUEE group underwent an exercise program using a motorized upper extremity exercise machine. All participants underwent a 4-week intervention with 30 min of exercise once a day for 5 days a week. Additionally, both groups received general physical therapy and functional electrical stimulation for 30 min twice a day for 5 days a week. Shoulder joint subluxation was measured by radiographic examination before and after training, and pain was evaluated in the splenius, upper trapezius, and infraspinatus muscles using pressure parameters. In addition, a manual muscle tester was used to assess the muscle strength of the shoulder joint flexors, extensors, abductors, adductors, and external and internal rotators, and the Fugl-Mayer Assessment (FMA) and Manual Functional Test (MFT) were used to evaluate upper extremity function. Results: A significant group-time interaction was observed for pain, with F-values of F(1, 26) = 7.470, p < 0.011 for the splenius and F(1, 26) = 9.623, p < 0.005 for the upper trapezius. A significant time-group interaction was observed for the muscle strength of the shoulder, with F-values of F(1, 26) = 13.211, p < 0.001; F(1, 26) = 4.974, p = 0.035 and F(1, 26) = 9.674, p = 0.004 for flexors, abductors, and external rotators, respectively. A significant time-group interaction was observed in the FMA, with F-values of F(1, 26) = 13.243, p < 0.001. When comparing the interaction effects between time and group for MFT scores, a significant difference was observed, with F-values of F(1, 26) = 32.386, p < 0.001. Conclusions: This study confirmed that sling-suspension-based active shoulder joint exercises are effective in improving shoulder joint subluxation, pain, muscle strength, and upper extremity function in patients with subacute stroke.

Postoperative PFME versus PFME alone for moderate SUI in pre-menopause women and influencing factors: a comparative effectiveness study.

PURPOSE: To explore the effectiveness of sling surgery followed by pelvic floor muscle exercises (PFME) or PFME alone for moderate stress urinary incontinence (SUI) in women and its influencing factors. METHODS: This is a prospective observational cohort study investigating whether sling surgery or PFME is preferred for pre-menopause women with moderate uncomplicated SUI. Those who received PFME alone or sling surgery were divided to PT or TVT group, respectively. The primary outcome was objective cure at 12 months. The secondary outcomes included Incontinence Impact Questionnaire-Short Form (IIQ-7) scores and PFME adherence. RESULTS: The study sample comprised 130 and 74 patients in the PT and TVT groups, respectively. There was 38.2% of patients adhered to PFME twice weekly or more often, and the compliance varied by education level. At 12 months, the objective cure rate was significantly higher in the TVT versus PT group (75.7% vs 47.7%; adjusted OR = 4.27; 95% CI, 2.05-8.87; P < 0.001). In addition, the mean reduction in IIQ-7 scores was greater in the TVT group (16.2 vs 10.0; adjusted OR = 3.38; 95% CI, 1.93-4.82; P < 0.001). However, among patients with lower education or those without adherence to PFME at 12 months, the TVT was also favorized, and the discrepancy in cure rates was greater between the two groups. CONCLUSION: Sling procedures followed by PFME demonstrate greater efficacy versus physiotherapy alone for moderate female SUI management. Continued adherence to PFME was important, even for patients undergoing sling procedures. Educational factors influenced patient PFME adherence and the advantage conferred by sling procedures.
