Pain resolution and functional outcomes of total mesh excision: a case series.

INTRODUCTION AND HYPOTHESIS: The objective was to assess the impact of total excision of polypropylene midurethral slings (MUS) on patient pain levels and to report on functional outcomes including recurrent/de novo stress urinary incontinence (SUI), sexual function, and quality of life measures. METHODS: This is a retrospective analysis of patients who underwent total MUS excision from March 2017 to December 2019. The primary outcome was the impact on pain assessed by a Numeric Rating Scale (NRS). Questionnaires analyzed were: Pain Catastrophizing Scale, Pelvic Floor Distress Inventory Short Form-20, Female Sexual Function Index, and McGill Pain Index questionnaires. RESULTS: Thirty-two women underwent total mesh excision within the inclusion period; with follow-up data available for 31 out of 32; 14 (43.8%) had previously undergone one or more partial vaginal mesh excision procedures. Types of MUS removed were: 14 (43.8%) transobturator midurethral slings, 12 (37.5%) retropubic midurethral slings, 4 (12.5%) mini-slings, and 2 (6.3%) mesh slings placed by laparotomy. Pain was the main reason for referral in 31 patients (96.9%). Mean pain NRS reduced from 6.1 pre-operatively to 3.3 post-operatively, with paired comparison showing a significant difference (p<0.01). Qualitatively, complete symptoms resolution was observed in 10 out of 31 (32.3%), another 9 out of 31 (29.0%) patients experienced clinically significant improvement, 2 out of 31 (6.5%) did not experience improvement in pain, and 10 out of 31 (32.3%) reported new/worsening pain. Post-operative complications occurred in 9 (29.0%) patients; all were Clavien-Dindo grade II. Nineteen (61.3%) reported de novo/recurrent SUI post-operatively. CONCLUSION: Total MUS mesh excision yields high complication and SUI recurrence rates, counter-balanced by a 61.3% pain resolution/improvement rate. These data are pertinent for patient counseling.

A risk calculator for postoperative urinary retention (POUR) following vaginal pelvic floor surgery: multivariable prediction modelling.

OBJECTIVE: To determine the perioperative characteristics associated with an increased risk of postoperative urinary retention (POUR) following vaginal pelvic floor surgery. DESIGN: A retrospective cohort study using multivariable prediction modelling. SETTING: A tertiary referral urogynaecology unit. POPULATION: Patients undergoing vaginal pelvic floor surgery from January 2015 to February 2020. METHODS: Eighteen variables (24 parameters) were compared between those with and without POUR and then included as potential predictors in statistical models to predict POUR. The final model was chosen as the model with the largest concordance index (c-index) from internal cross-validation. This was then externally validated using a separate data set (n = 94) from another surgical centre. MAIN OUTCOME MEASURE: Diagnosis of POUR following surgery while the patient was in hospital. RESULTS: Among the 700 women undergoing surgery, 301 (43%) experienced POUR. Preoperative variables with statistically significant univariate relationships with POUR included age, menopausal status, prolapse stage and uroflowmetry parameters. Significant perioperative factors included estimated blood loss, volume of intravenous fluid administered, operative time, length of stay and specific procedures, including vaginal hysterectomy with intraperitoneal vault suspension, anterior colporrhaphy, posterior colporrhaphy and colpocleisis. The lasso logistic regression model had the best combination of internally cross-validated c-index (0.73, 95% CI 0.71-0.74) and a calibration curve that showed good alignment between observed and predicted risks. Using this data, a POUR risk calculator was developed (https://pourrisk.shinyapps.io/POUR/). CONCLUSIONS: This POUR risk calculator will allow physicians to counsel patients preoperatively on their risk of developing POUR after vaginal pelvic surgery and help focus discussion around potential management options.

The effect of local estrogen therapy on the urinary microbiome composition of postmenopausal women with and without recurrent urinary tract infections.

INTRODUCTION AND HYPOTHESIS: Recurrent urinary tract infections (rUTIs) occur in 2-10% of postmenopausal women. Local estrogen therapy (LET) has been shown to reduce UTIs. This study aimed to compare the urinary microbiome between patients with and without a history of rUTIs and to examine whether treatment with LET influences the diversity and richness of microbiome species in two groups. METHODS: Postmenopausal women with and without rUTIs attending the urogynecology clinic between April 2019 and December 2020 were recruited. Participant baseline characteristics and demographics were recorded. Aseptic transurethral urine samples were collected at recruitment and at 3-6 months following treatment with LET. The V1-V2 and ITS regions of the 16S rRNA gene were sequenced to identify bacteria. RESULTS: A total of 37 women were recruited, 20 controls and 17 patients with rUTI. During follow-up, symptomatic UTIs occurred in 3/17 (17.6%) and 0/20 in the rUTI group and control group, respectively. Klebsiella aerogenes was present in 80% of rUTI samples and in 53.3% of control samples before LET. Abundance of Finegoldia magna was present in 33.3% of samples before LET, but only in 6.7% after LET. There was no change in relative abundance of lactobacillus species following LET in both groups. CONCLUSIONS: Treatment with vaginal LET altered the local hormonal environment of the urinary bladder and likely protected women from development of rUTI by decreasing the presence of F. magna. To confirm the significance of this bacterial species in rUTI symptomatology, our finding needs to be validated on a larger patient cohort.

The extended pessary interval for care (EPIC) study: a failed randomized clinical trial.

INTRODUCTION AND HYPOTHESIS: To describe study design flaws and limited outcomes of a randomized trial that intended to compare satisfaction and complication rates between patients managing their pelvic organ prolapse with a pessary at different maintenance intervals. METHODS: A randomized clinical trial was conducted at two tertiary pessary clinics. After a successful fitting, patients were randomly allocated to follow-up at 3-month or 6-month intervals and followed for 12 months. Symptoms, complications, and pelvic examination characteristics were recorded at each visit. At 6 and 12 months, patient satisfaction with the pessary was also recorded. Sample size calculation was based on the minimal relevant difference in Pessary Satisfaction score (created for this study). With a power of 0.8 and an alpha of 0.05, the minimum number of patients required in each group was 28. RESULTS: We were unable to reach our sample size as most patients did not meet inclusion criteria. After 2 years we were only able to recruit 20/56 patients, with 9 patients in the 3-month group and 11 patients in the 6-month group. Additionally, seven patients dropped out of the study. Overall satisfaction was high and similar between groups at 6- and 12-month follow-up visits. Pessary complications were noted in both groups but in low numbers. CONCLUSIONS: Pessary use is associated with high patient satisfaction and low complication rates, regardless of the follow-up interval. The recruitment failure demonstrated that a randomized trial is not feasible for this research question. Optimally, pessary follow-up should be based on patient symptoms and scheduling preference.

Antibiotic prophylaxis for urodynamic testing in women: a systematic review.

INTRODUCTION AND HYPOTHESIS: Urinary tract infection is the most common complication after urodynamic studies (UDS). Practice guidelines recommend against antibiotic prophylaxis based on an outdated review of the literature, which advised on the premise of "a lack of good quality studies" and based on an assumed low incidence not consistently supported by the literature. OBJECTIVES: This systematic review aims to update the assessment of the efficacy of antibiotic prophylaxis compared with placebo or no treatment for prevention of urinary tract infection in females over the age of 18 years undergoing UDS. METHODS: MEDLINE, EMBASE, COCHRANE, DISSERTATIONS, conference proceedings and clinical trial registries were searched for relevant randomized controlled trials. Two authors independently screened and selected articles, assessed these for quality according to Cochrane guidelines and extracted their data. RESULTS: A total of 2633 records were screened, identifying three relevant randomized controlled trials. The one study that was critically appraised as being the least likely biased showed a statistically significant effect of antibiotic prophylaxis in reducing bacteriuria post UDS in female patients. The other two studies included in the review did not. None of the studies included were powered to show a significant change in the incidence of urinary tract infection following UDS in female patients receiving antibiotic prophylaxis versus no prophylaxis. CONCLUSIONS: Similar to the 2012 Cochrane review on this subject, this systematic review demonstrated that antibiotic prophylaxis may decrease bacteriuria in women post UDS; however, further research is required to assess its effect on urinary tract infections in this context.

Long-Term Experience with Modified McCall Culdoplasty in Women Undergoing Vaginal Hysterectomy for Pelvic Organ Prolapse.

OBJECTIVE: The incidence of post-hysterectomy vault prolapse following native tissue repair has been reported to be as high as 43%. The optimal way to maintain vault support is unknown. Our aim was to evaluate the long-term efficacy of modified McCall culdoplasty during vaginal hysterectomy for symptomatic uterine prolapse in preventing the recurrence of vaginal vault prolapse. METHODS: We conducted a retrospective chart review involving 490 patients who underwent vaginal hysterectomy with modified McCall culdoplasty, with or without a concomitant stress incontinence procedure, between January 2008 and December 2018 at Mount Sinai Hospital in Toronto. Data analyzed included patient demographics, preoperative prolapse staging, intraoperative and postoperative complications, and postoperative subjective and objective success rates. RESULTS: A total of 490 patients underwent vaginal hysterectomy with modified McCall culdoplasty. The mean follow-up period was 2.8 years. The objective success rate of vault support was 97.1%, and the subjective success rate was 94.1%. The total rate of reoperation for recurrence of vault prolapse was 1.0%. The objective cystocele recurrence rate was 8.6%, and 2.4% of these cases required reoperation. The objective rectocele recurrence rate was 4.7%, with 1.2% requiring reoperation. Unilateral ureteric kinking requiring intraoperative release of the McCall suture was recorded for 2.9% of patients. Overall, there was significant improvement in urinary, bowel, and prolapse symptoms post procedure. CONCLUSION: This cohort of patients who underwent modified McCall culdoplasty had low rates of vault prolapse recurrence and prolapse symptoms. The modified McCall culdoplasty technique practised at our institution is safe and effective in preventing post-hysterectomy vault prolapse.

Risk factors and outcome of repair of obstetric anal sphincter injuries as followed up in a dedicated perineal clinic.

INTRODUCTION AND HYPOTHESIS: Faecal incontinence can be a devastating outcome with social, psychological and physical repercussions, and it occurs in 10-61% following obstetric anal sphincter injury (OASIS). The aim of our study was to determine the contributing factors in the development of severity of OASIS and to correlate anal sphincter tone with the extent of anal sphincter injury. METHODS: A prospective cohort study was performed of all patients attending the postnatal perineal clinic at 4-12 months postpartum, from January 2016 until October 2017. Women were categorised into minor tears (3a and 3b) and major tears (3c and 4th degree). RESULTS: The mean age was 33.9 years (4.2); the mean parity was 1.6 (range 1-5). A total of 75 women (17%) were reviewed following a major tear (4th degree, n = 28, 3c, n = 47) and 362 (83%) were reviewed following a minor tear (3a n = 188, 3b, n = 174). Following analysis of numerous obstetric variables, it was shown that women who had an instrumental delivery were more likely to have a major tear compared with those who had a spontaneous vaginal delivery (p = 0.05). A significant difference was found in the distributions of symptom score between groups (p < 0.001). Women with combined defects were most likely to have reduced anal tone (p < 0.001) compared with any other group. CONCLUSIONS: The perineal clinic provides a valuable resource for investigation and treatment of OASIS, providing a targeted pathway for management. We suggest that endoanal ultrasound and digital rectal examination are complimentary investigations which correlate well with each other.

How do patients and surgeons decide on uterine preservation or hysterectomy in apical prolapse?

Increasingly, uterine preservation surgeries are being performed for treating apical prolapse. Several types of procedures and surgical approaches to correct apical prolapse have been described in the literature. Despite this, there remains inadequate information to provide evidence-based recommendations regarding the optimal treatment approach and materials to use, and trials are ongoing to identify the optimal techniques. In the future, our patients may be the strongest determining influence when it comes to choice of apical prolapse surgery, with factors such as autonomy, reproduction, intimacy and fear influencing their decision. It is our opinion that the two most powerful forces behind the choice of apical POP surgical technique are the woman's personal desire for uterine preservation or not and the surgeon's personal choice of procedure based on training received. Present management of apical prolapse involves understanding patient goals and acknowledging their treatment preferences and values.

Prophylactic Negative Pressure Dressing Use in Closed Laparotomy Wounds Following Abdominal Operations: A Randomized, Controlled, Open-label Trial: The P.I.C.O. Trial.

OBJECTIVE: A randomized controlled trial was undertaken to investigate the effect of prophylactic negative pressure dressings on postoperative surgical site infection (SSI) rates in closed laparotomy wounds. SUMMARY OF BACKGROUND DATA: Laparotomy wounds are associated with high rates of SSI. The effect of prophylactic negative pressure dressing of closed incisional wounds on SSI rate is unknown. METHODS: A randomized, controlled, open-label trial was conducted (clinicaltrials.gov registration number NCT02780453). Fifty patients undergoing open abdominal surgery were included, with 25 patients randomized to the negative pressure dressing group and 25 to the standard dressing group. The primary endpoint was SSI incidence at 30 days postoperatively. Secondary endpoints included SSI incidence at 4 days, length of stay, cosmetic outcome, and patient satisfaction. Statistical analysis was performed on a per-protocol basis using SPSS version 23.0. RESULTS: The incidence of SSI at 30 days postoperatively was significantly reduced in the treatment group compared with the control group [8.3% vs 32.0%, P = 0.043 (1-sided), P = 0.074 (2-sided)]. There was no difference in SSIs at 4 days postoperatively [4.1% vs 8.0%, P = 0.516 (1-sided), P = 1.0 (2-sided)]. Analysis of predictors of wound infection identified standard wound dressings as the only significant predictor of SSI development. Length of stay was significantly reduced in the negative pressure dressing group [6.1 vs 14.7 days, P = 0.019 (2-sided)]. Cosmetic outcome and patient satisfaction did not show any difference between the 2 groups. CONCLUSIONS: Prophylactic use of negative pressure dressings for closed laparotomy wounds significantly reduces the incidence of SSI at 30 days postoperatively.

The relationship between maternal body composition in early pregnancy and foetal mid-thigh soft-tissue thickness in the third trimester in a high-risk obstetric population.

Maternal obesity is an emerging challenge in contemporary obstetrics. To date there has been no study analysing the relationship between specific maternal body composition measurements and foetal soft-tissue measurements. The aim of this study was to determine whether measurement of maternal body composition at booking predicts foetal soft-tissue trajectories in the third trimester. We analysed the relationship between foetal thigh in the third trimester and both maternal BMI and body composition using the Tanita digital scales in the first trimester. Foetal subcutaneous thigh tissue measurements were obtained at intervals of 28, 32 and 36 weeks of gestation. A total of 160 women were identified. There was a direct correlation between MTST at 36 weeks and BMI (p = .002). There was a positive correlation between MTST at 36 weeks and leg fat mass (p = .13) and leg fat free mass (p = .013). There was a positive correlation between arm fat free mass and MTST at 36 weeks. We showed there is an association between maternal fat distribution and foetal subcutaneous thigh tissue measurements. MTST may be more useful in determining if a child is at risk of macrosomia. Impact statement Previous studies have suggested that maternal obesity programmes intrauterine foetal adiposity and growth. The aim of this study was to examine the relationship in a high-risk obstetric population between measurements of maternal body composition in early pregnancy and the assessment of foetal adiposity in the third trimester using serial ultrasound measurements of mid-thigh soft-tissue thickness. BMI is only a surrogate measurement of fat and does not measure fat distribution. Our study shows the distribution of both maternal fat and fat-free mass in early pregnancy may be positively associated with foetal soft-tissue measurements in the third trimester. Maternal arthropometric measurements other than BMI may help predict babies at risk of macrosomia and neonatal adiposity.

Tubo-ovarian abscess after vaginal delivery: A case report and review of current literature.

Tubo-ovarian abscesses in pregnancy and the post-partum period are extremely rare. We report a case of a 31-year-old woman who presented with an acute abdomen and sepsis in the post-partum period with a background of a large endometrioma diagnosed prior to conception. Exploratory laparoscopy revealed a ruptured tubo-ovarian abscess which was surgically drained and then treated with intravenous antibiotics. This report is seemingly unique in presenting the development of antenatal endometrioma into a tubo-ovarian abscess and an unusual differential for abdominal pain to consider in the immediate postpartum period.

Aftermath of a Midurethral Sling Placed in the First Trimester: A Case Report.

There are limited data on the management of pregnancy and delivery after midurethral sling (MUS) surgery for stress urinary incontinence (SUI). We report a case of a 39-year-old woman who underwent an MUS in July 2017. She reported a 10-year history of frequency, urgency with rare urge incontinence, nocturia, and occasional SUI when coughing or sneezing. Preoperative assessment did not include a pregnancy test. Two days after MUS placement, she developed complete urinary retention, and it was determined that she was 6 weeks pregnant. She was referred to a tertiary urogynecology unit and was seen at 23 weeks' gestation with worsening symptoms of urinary frequency and nocturia. She also described difficulty voiding but no incontinence. She was managed with conservative measures initially, but by 35 weeks, she required intermittent self-catherization (ISC). She underwent an elective cesarean delivery at 39 weeks' gestation. She reported postvoid dribbling, urge incontinence, and recurrent SUI at 10 months postpartum. This case report adds to the body of knowledge around outcomes of MUS during and after pregnancy.

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

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

Severe hyponatraemia associated with pre-eclampsia.

Pre-eclampsia is a multisystem disorder with incidence rates ranging from 2% to 5%. Hyponatraemia is a rare complication of pre-eclampsia. A 41-year-old, para 0+1 in vitro fertilisation monochorionic diamniotic triplet pregnancy woman presented at 25 weeks with dyspnoea and general malaise. Her antenatal course was complicated by the diagnosis of intrauterine growth restriction in triplet one at 27 weeks of gestation. At 27+3 weeks gestation, she was diagnosed as having pre-eclampsia. Subsequent biochemical analysis demonstrated hyponatraemia with serum sodium falling steadily to 117 mmol/L over the next 19 days. She was admitted to intensive care unit for stabilisation of fulminant pre-eclampsia and severe hyponatraemia at 30+5 weeks of gestation. Hypertonic saline and intravenous labetolol were administered prior to delivery by caesarean section. She recovered well postdelivery with stabilisation of her blood pressure and normalisation of her sodium level to 135 mmol/L. Awareness and frequent monitoring of hyponatraemia should become an integral part of monitoring women with pre-eclampsia.
