Standing open magnetic resonance imaging improves detection and staging of pelvic organ prolapse.

INTRODUCTION: The role of imaging in pelvic organ prolapse (POP) assessment is unclear. Open magnetic resonance imaging (MRI) systems have a configuration that allows for imaging women with POP in different positions. Herein, we use a 0.5 Tesla open MRI to obtain supine, seated, and standing images. We then compare these images to evaluate the impact of posture on detection and staging of POP. METHODS: Women presenting with symptoms of POP at a tertiary care university hospital were asked to participate in this prospective cohort study. Symptom scores, POP-Q staging and three-position MRI imaging of the pelvis data were collected. The pubococcygeal line (PCL) was used to quantify within-patient changes in pelvic organ position as defined by: no displacement, <1 cm inferior to the PCL, mild (1-3 cm), moderate (3.1-6 cm), and severe (>6 cm) in the axial and sagittal T2-weighted images. Statistical analysis was completed (T-test; p<0.05 significant). RESULTS: A total of 42 women, age range 40-78 years, participated. There was a significant difference in the mean values associated with anterior prolapse in the supine (0.7±1.8), seated (2.4±3.4), and upright (4.2±1.6) positions (p=0.015). There was a significant difference in the mean values associated with apical prolapse in the supine (0.5±1.5), seated (1.5±1.4), and upright (2.1±1.5) positions (p=0.036). CONCLUSIONS: Our findings suggest that POP is more readily detected and upstaged with standing MRI images as compared to supine and seated positions. The developed two-minute standing MRI protocol may enable clinicians to better assess the extent of POP.

Two Intraoperative Techniques for Midurethral Sling Tensioning: A Randomized Controlled Trial.

OBJECTIVE: To evaluate whether the use of a Mayo Scissor as a suburethral spacer compared with a Babcock clamp holding a loop of tape under the urethra results in different rates of abnormal bladder outcomes 12 months after retropubic midurethral sling surgery. METHODS: The MUST (Mid-Urethral Sling Tensioning) trial was a block-randomized, double-blind, multicenter clinical trial that allocated women to have their retropubic midurethral slings tensioned by Scissor or Babcock technique. The primary outcome (abnormal bladder) was a composite of persistent stress urinary incontinence (SUI), overactive bladder, and urinary retention. Secondary outcomes included outcomes of the composite, postoperative catheterization, incontinence-related questionnaires, repeat incontinence treatment, and uroflowmetry. Sample size of 159 in each arm (N=318) was planned for a superiority trial, hypothesizing a 10% difference in primary outcome. RESULTS: From September 2015 to December 2017, 506 women were screened and 318 were randomized. Baseline characteristics were similar in each arm. At 12 months, 253 (79.6%) women provided information on primary outcome: 40 of 128 (31.3%) patients with midurethral slings tensioned by Scissor experienced abnormal bladder, compared with 23 of 125 (18.4%) of those with midurethral slings tensioned by Babcock (P=.018, relative difference 12.9%). Secondary analyses favored Babcock for median duration of catheterization and the proportions of women experiencing urinary retention requiring sling lysis. Uroflowmetry parameters suggest the Scissor technique is more restrictive. Rates of mesh erosion were lower for the Scissor arm. No differences occurred in proportions of women experiencing patient reported persistent SUI after surgery. CONCLUSION: Abnormal bladder outcomes were 12.9% less frequent for women with midurethral slings tensioned by Babcock. Both techniques provided a comparable patient reported cure for SUI at 12 months. Women with midurethral slings tensioned by Scissors experienced more intervention for obstruction, whereas those with midurethral slings tensioned by Babcock experienced higher rates of mesh erosion. This information about how the postoperative courses differ allows surgeons to better counsel patients preoperatively or tailor their choice of technique.

Mid-urethral slings on YouTube: quality information on the internet?

INTRODUCTION AND HYPOTHESIS: Scant literature exists about the quality of urogynecological content on social media. Our objective was to measure the accuracy and comprehensiveness of YouTube videos related to mid-urethral sling (MUS) procedures. METHODS: YouTube was searched using the terms "mid-urethral sling," "vaginal tape," "TVT," "TOT," "TVT surgery," and "TOT surgery." Duplicates and videos with less than 1,000 views were excluded. We developed a standardized questionnaire for this project, assessing each video's target audience, main purpose, relevance, informed consent elements, surgical steps, and bias. The primary outcome was the presence of all elements of informed consent. Inter-rater reliability (IRR) was calculated using the Fleiss' kappa statistic. Descriptive statistics were also obtained. RESULTS: Five reviewers each rated 56 videos. Mean IRR was moderate (Fleiss' kappa 0.58 ± 0.24). Video content was classified as physician educational material (67.9 %), patient information (16.1 %), advertisement (10.7 %), lawsuit recruitment (1.8 %), and unclear (3.6 %). MUS was the primary topic for 82.1 % of the videos. The remainder discussed other types of anti-incontinence procedures or prolapse surgery. None of the videos mentioned all four elements of informed consent. Of 32 videos demonstrating surgical technique, none showed the complete list of pre-determined surgical steps. The mean number of listed steps was 7.6/16. Only four videos mentioned at least one post-operative patient instruction. A marketing element was shown in 26.8 % of videos. CONCLUSIONS: Patient information about MUS on YouTube is lacking and often biased. Physicians and students viewing YouTube videos for educational purposes should be cognizant of the variability in the surgical steps demonstrated.

Evaluation of educational content of YouTube videos relating to neurogenic bladder and intermittent catheterization.

INTRODUCTION: Many patients conduct internet searches to manage their own health problems, to decide if they need professional help, and to corroborate information given in a clinical encounter. Good information can improve patients' understanding of their condition and their self-efficacy. Patients with spinal cord injury (SCI) featuring neurogenic bladder (NB) require knowledge and skills related to their condition and need for intermittent catheterization (IC). METHODS: Information quality was evaluated in videos accessed via YouTube relating to NB and IC using search terms "neurogenic bladder intermittent catheter" and "spinal cord injury intermittent catheter." Video content was independently rated by 3 investigators using criteria based on European Urological Association (EAU) guidelines and established clinical practice. RESULTS: In total, 71 videos met the inclusion criteria. Of these, 12 (17%) addressed IC and 50 (70%) contained information on NB. The remaining videos met inclusion criteria, but did not contain information relevant to either IC or NB. Analysis indicated poor overall quality of information, with some videos with information contradictory to EAU guidelines for IC. High-quality videos were randomly distributed by YouTube. IC videos featuring a healthcare narrator scored significantly higher than patient-narrated videos, but not higher than videos with a merchant narrator. About half of the videos contained commercial content. CONCLUSIONS: Some good-quality educational videos about NB and IC are available on YouTube, but most are poor. The videos deemed good quality were not prominently ranked by the YouTube search algorithm, consequently user access is less likely. Study limitations include the limit of 50 videos per category and the use of a de novo rating tool. Information quality in videos with healthcare narrators was not higher than in those featuring merchant narrators. Better material is required to improve patients' understanding of their condition.

Positional pelvic organ prolapse (POP) evaluation using open, weight-bearing magnetic resonance imaging (MRI).

INTRODUCTION: Magnetic resonance imaging (MRI) of patients with pelvic organ prolapse (POP) is completed in the supine position. Open magnetic resonance imaging (MRO) uses vertical magnets, allowing imaging in a variety of upright postures. This pilot study used MRO to evaluate the change of prolapse in different positions compared to non-prolapsed images. METHODS: In total, 11 women (6 POP, 5 controls) aged 24 to 65 years had 12 MRO images (midline sagittal pelvic line) consecutively when supine, sitting and standing with a full and empty bladder. Lengths between the lowest point of the bladder to the pubococcygeal (PC) and pubopromontoreal (PP) lines in each image were compared, and the ratio of bladder area under the PC and PP lines to the total bladder area. RESULTS: Significant elongation between the PC line and lowest point of the bladder was evident in subjects with POP comparing supine and standing images (p = 0.03), but not controls (p = 0.07). Similarly, this axis was significantly longer in cystocele subjects versus controls only in the standing position. Bladder area under the PC line was significantly increased between supine and standing positions only among subjects with cystocele (p < 0.01), and significantly larger among the study group in the standing position (p < 0.005), less significant in the supine position (p = 0.015), and not significant in the sitting position (p = 0.3). CONCLUSIONS: MRO imaging allows us to investigate the effects of upright position and weight bearing on the staging of POP. Imaging patients when sitting and standing identified that significant changes occur in the maximal descent of the bladder.

An integrative review and severity classification of complications related to pessary use in the treatment of female pelvic organ prolapse.

INTRODUCTION: Pessary use is the preferred non-surgical treatment option for female pelvic organ prolapse. As pessaries can be used chronically to alter pelvic floor anatomy, consideration of short-and long-term complications is important in patient management. We systematically reviewed articles describing the complications of pessary use to determine frequency and severity. METHODS: A systematic search via MEDLINE and PubMed using the key terms "complications," "pessary," "pelvic organ prolapse," "side effects" was conducted for the years 1952 to 2014 inclusively. Selected articles cited in the publications identified were also considered. Only full-text material published in English was reviewed. All pessary-related complications described were collated; overall frequency within case reports and case series were calculated and severity was graded using the Clavien-Dindo classification. RESULTS: In total, 61 articles met the inclusion criteria. The most common complications reported were vaginal discharge/vaginitis, erosion, and bleeding. Complications were related to pessary shape and material, and duration in situ. Clavien-Dindo classification of complication severity found that all 5 grade levels were attributed to pessary use; serious grade 4 and 5 complications included cancer, adjacent organ fistula and death. CONCLUSION: There are few detailed reports of complications of pessary use relative to the estimated frequency of pessary use worldwide. Prospective studies documenting complications by shape, material, and size, and objectively classifying complication severity are required. As serious grade 4 and 5 complications of pessary use occur, further development of clinical follow-up guidelines for long-term pessary users is justified.

A rare complication of suprapubic catheterisation following pelvic reconstructive surgery for urinary incontinence.

Suprapubic (SP) catheterisation is commonly used for drainage of the bladder following pelvic surgery. Although it is a widely employed procedure, it is not without complications, such as infection and blockage. The authors report a rare complication of SP catheterisation involving a persistent SP catheter site fistulous tract and an infected haematoma significantly complicating a patient's postoperative course. Wound debridement, bladder drainage and a prolonged course of antibiotics were employed to successfully treat this complication. The exact mechanism of her complication is only speculative, however to our knowledge no similar cases of a fistula after removal of a SP catheter used for short-term bladder drainage have been reported.

A 56-year-old woman with early acute pulmonary emboli following pelvic reconstructive surgery.

Venous thromboembolism (VTE) remains a significant cause of postoperative morbidity and mortality. There are few reports on acute symptomatic pulmonary embolism (PE) following urogynaecological surgery. The authors report a case of an adult woman who developed a massive acute PE early on postoperative day 1 following a complex reconstructive surgery. Following anticoagulation treatment and placement of an inferior vena cava filter, the patient recovered and was discharged without discomfort on the ninth postoperative day. While recognition of the early occurrence of VTE is important to ensure optimal patient care following major pelvic surgery, this case highlights the need to reconsider VTE prophylaxis protocols in moderate to high-risk populations undergoing elective surgery.
