The incidence of low-pressure urethra as a function of prolapse-reducing technique in patients with massive pelvic organ prolapse (maximum descent at all vaginal sites) ☆ ☆☆ ★

OBJECTIVE Our aims were to compare several prolapse-reducing techniques during urodynamic evaluation and prospectively evaluate their usefulness in identifying the incidence of low urethral closure pressure in continent patients with massive prolapse. STUDY DESIGN This preoperative, prospective, repeated-measures urodynamic study evaluated the maximum urethral closure pressure with the use of four different techniques in 30 consecutive continent patients with grade 4 prolapse at all vaginal sites. Twenty patients with grade 0 prolapse served as the control group. All patients from the prolapse group underwent surgical treatment and were followed up clinically for a minimum of 1 year. RESULTS Use of the Scopette (Birchwood Laboratories, Eden Prairie, Minn.) reduction technique to reduce the prolapse in a linear orientation during multichannel urodynamics revealed a 56% incidence of low-pressure urethra and an overall genuine stress urinary incontinence of 83% in patients with massive pelvic organ prolapse but without clinical urinary incontinence. CONCLUSIONS There may be an increased indication for sling urethropexy in patients with massive prolapse.

In patients with rectoceles and obstructed defecation syndrome, surgery should be the option of last resort

BACKGROUND The indications for operation in patients with obstructed defecation syndrome (ODS) with rectocele are not well defined. METHODS A total of 90 female patients with ODS and rectocele were prospectively evaluated and treated with fiber supplements and biofeedback training. Univariate and multivariate regression was used to determine factors predictive of failing medical management. RESULTS Obstructive symptoms were the most prevalent presenting complaint (82.2%). Ultimately, 71.1% of patients responded to medical management and biofeedback. Multivariate regression analysis suggested that the presence of internal intussusception was associated with a lower chance of undergoing surgery to address ODS symptoms [odds ratio 0.18; P = .05], whereas inability to expel balloon, contrast retention on defecography, and splinting were not (P ≥ .15). CONCLUSION Rectoceles with concomitant intussusception in patients with ODS appear to portend a favorable response to biofeedback and medical management. We argue that all patients considered for surgery for rectoceles because of ODS should first undergo appropriate bowel retraining.

Minimally invasive apical sacropexy: a retrospective review of laparoscopic and robotic operating room experiences.

Objectives Minimally invasive apical sacropexies (MI-APSC) can be performed using robotics or laparoscopy. We hypothesized that operative characteristics of MI-APSC, laparoscopic (LSC) and robotic (RSC), were similar. The objective of our study was to compare operative characteristics, objective prolapse outcomes, and robotic learning curve. Methods Ninety-two women planning MI-APSC for treatment of apical pelvic organ prolapse from 2006 to 2010 were included in the study. The primary outcome was operative time. The secondary outcomes included estimated blood loss, rate of conversion, intraoperative complications, hospital stay, and objective prolapse outcome. We also analyzed the robotic learning curve. Statistical analysis included independent samples t test, Wilcoxon rank sum test, &khgr;2, and multiple logistic regressions; significance was set at P < 0.05. Learning curve was graphed with moving average and analyzed with moving block technique. Results Forty-eight RSCs and 43 LSCs were analyzed. Mean operative times were LSC, 238 ± 59 minutes; and RSC, 242 ± 54 minutes. Robotic MI-APSC setup was longer (P = 0.02). Complications, conversions, estimated blood loss and hospital stay were low and similar between groups. Patients’ characteristics were similar. Concomitant procedures produced longer operative times. Conclusions Operating room experiences with laparoscopic- and robotic-assisted approaches to MI-APSC were similar, but setup time is longer for the robotic-assisted approach. The robotic learning curve is short for surgeons who have experience with LSC.

Impact of Rising Grades of Internal Rectal Intussusception on Fecal Continence and Symptoms of Constipation.

BACKGROUND: A theory of rectal intussusception has been advanced that intrarectal intussusception, intra-anal intussusception, and external rectal prolapse are points on a continuum and are a cause of fecal incontinence and constipation. OBJECTIVE: This study evaluates the association among rectal intussusception, constipation, fecal incontinence, and anorectal manometry. DESIGN: Patients undergoing defecography were studied from a prospectively maintained database and classified according to the Oxford Rectal Prolapse Grade as normal or having intra-rectal, intra-anal, or external intussusception. Patient symptoms were assessed using the Constipation Severity Index and the Fecal Incontinence Severity Index. Quality-of-life surveys were also used. Patients also underwent anorectal manometry. SETTINGS: The study was conducted at a tertiary care university medical center (Massachusetts General Hospital). PATIENTS: The study included 147 consecutive patients undergoing evaluation for evacuatory dysfunction and involved defecography, symptoms questionnaires, and anorectal physiology testing from January 2011 to December 2013. MAIN OUTCOME MEASURES: Symptom severity and quality-of-life scores were measured, as well as anal manometry results. RESULTS: Increasing Oxford grade was associated with an increase in severity of fecal incontinence (median score: normal = 23.9, intrarectal = 21.0, intra-anal = 30.0, external prolapse = 35.3; &bgr; = 4.71; p = 0.009), which persisted in a multivariable model including age (&bgr; = 2.13; p = 0.03), and decreased sphincter pressures (median mean resting pressure: normal = 75.4, intra-rectal = 69.7, intra-anal = 64.3, external prolapse = 48.3; &bgr; = –8.57; p = 0.003), which did not persist in a multivariable model. Constipation severity did not increase with rising intussusception (mean score: normal = 37.4, intrarectal = 35.0, intra-anal = 41.4, external prolapse = 32.9; p = 0.79), and balloon expulsion improved rather than worsened (normal = 47.1%, intrarectal = 60.5%, intra-anal = 82.9%, external prolapse = 93.1%; p < 0.001). LIMITATIONS: The study was limited because it was an observational study from a single center. CONCLUSIONS: Increasing grades of rectal intussusception are associated with increasing fecal incontinence but not constipation.

Clinical application of IUGA/ICS classification system for mesh erosion

Our aim was to assess the usability of the IUGA/ICS classification system for mesh erosion in a tertiary clinical practice and to determine if assigned classification is associated with patient symptoms, treatment, and outcome.

Effect of Coexisting Pelvic Floor Disorders on Fecal Incontinence Quality of Life Scores: A Prospective, Survey-Based Study.

BACKGROUND: The association between an objective measure of fecal incontinence severity and patient-reported quality of life is poorly understood. OBJECTIVE: The purpose of this study was to evaluate patients with various degrees of fecal incontinence to determine whether their quality of life as measured by the Fecal Incontinence Quality of Life Scale is affected by coexisting pelvic floor disorders. DESIGN: This was a prospective, survey-based study. SETTINGS: The study was conducted at a tertiary pelvic floor disorders center. PATIENTS: Included patients were all of those presenting between January 2007 and March 2014. MAIN OUTCOME MEASURES: Survey data were analyzed to determine the association between Fecal Incontinence Severity Index and Fecal Incontinence Quality of Life Scale, as well as scores from the Constipation Severity Instrument, Pelvic Floor Impact Questionnaire, Pelvic Organ Distress Inventory, and Urinary Distress Inventory. RESULTS: A total of 585 patients reported fecal incontinence ranging from none (n = 191) to mild/moderate (n = 159) to severe (n = 235). As expected, patients with severe fecal incontinence have worse scores on all fecal incontinence quality-of-life subscales (lifestyle, coping/behavior, depression/self-perception, and embarrassment) and worse colorectal/anal symptoms than those with mild/moderate or no fecal incontinence (p < 0.0001). Patients with severe fecal incontinence also have worse bladder/urinary symptoms (p ⩽ 0.0001). Pelvic organ prolapse and constipation symptoms were similar between groups (p ≥ 0.61). After correcting for baseline differences in patient comorbidities and bladder/urinary symptoms, a significant association persisted between Fecal Incontinence Severity Index and all of the subscales of the fecal incontinence quality-of-life instrument (p < 0.0001). However, urinary distress scores also remained significantly associated with all of the fecal incontinence quality-of-life subscales except for embarrassment after risk adjustment (p < 0.01). LIMITATIONS: Nongeneral population and a lack of patient data on previous medical management of fecal incontinence were limitations of this study. CONCLUSIONS: The Fecal Incontinence Quality of Life Scale correlates strongly with instruments measuring both fecal and urinary incontinence. This underscores the importance of quantifying the presence or absence of coexistent urinary leakage in studies where a drop in fecal incontinence quality of life is considered a primary end point.

Hormone Modulation of Toll-Like Receptor 5 in Cultured Human Bladder Epithelial Cells

AIM The effect of hormone levels on the stimulation of Toll-like receptor 5 (TLR5) in the bladder is unknown. We aimed to study the effect of estradiol and progesterone on TLR5 expression and function in human bladder epithelial cells. METHODS After growing to near confluence, T24 human urinary bladder (HUB) cells were incubated in hormone-free (HF) media for 72 hours. Human urinary bladder cells were then incubated in (1) HF media, (2) estradiol media, (3) progesterone media, or (4) media containing estradiol and progesterone at physiologic concentrations. Following flagellin exposure, cells and media were collected. Toll-like receptor 5 expression and stimulated cytokine release were analyzed using enzyme-linked immunosorbent assays. Results were normalized with cellular protein assays. A TLR5 antagonist was used to confirm that stimulation from flagellin was mediated by TLR5 signaling. RESULTS Cultured HUB cells express TLR5 protein. Estradiol and progesterone environments suppress TLR5 expression compared to HF environment. The function of TLR5 was measured by interleukin 6 (IL-6) and monocyte chemoattractant protein 1 production after flagellin exposure. Interleukin 6 production was 75% higher in the estradiol than progesterone environment. The progesterone environment produced IL-6 levels twice that observed in HF and combined estrogen-progesterone environments. Interestingly, higher TLR5 expression was associated with lower IL-6 production. CONCLUSION Our study demonstrated that TLR5 expression and functional activity as measured by IL-6 are modulated by hormones. The increase in TLR5-associated IL-6 may play a role in increasing the rate of symptomatic urinary tract infection. Likewise, low TLR5 functional activity may dampen the response of the innate immune system, thereby lessening the likelihood of a symptomatic bladder infection.Aim: The effect of hormone levels on the stimulation of Toll-like receptor 5 (TLR5) in the bladder is unknown.

Predictors for Voiding Trial Failure after Minimally Invasive Sacrocolpopexy

Introduction: Catheter associated urinary tract infections (CAUTIs) due to indwelling catheters pose a serious health and financial burden in the US. Patients who undergo reconstructive pelvic surgery experience postoperative voiding dysfunction at a significant rate, requiring prolonged catheterization. The preoperative identification of patients at highest risk of failing a backfill trial of void (TOV) would allow for selected instruction in self-catheterization techniques and minimize the prevalence in dwelling catheters. Objective: To identify predictors for voiding trial failure after minimally-invasive (laparoscopic or robot-assisted) sacrocolpopexy for surgical correction of prolapse in patients who did not undergo a concomitant urinary anti-incontinence procedure. Methods: All subjects undergoing minimally-invasive sacrocolpopexy without concomitant anti-incontinence surgery from October 2006 to July 2010 at our institution were included. Patient characteristics including basic demographics, medical and surgical history, operative characteristics, and baseline preoperative urodynamic testing were included. The data was analyzed with logistic regression for continuous variables and Pearson chi-squared test for dichotomous variables (Stata IC-13). Results: 56 subjects were identified. Of those, 5 subjects (8.9%) failed a postoperative voiding trial. No significant association between examined variables and failure of trial of void were observed. Concomitant vaginal surgery approached significance with a p-value of 0.058. Conclusion:The percentage of subjects that failed a voiding trail was comparable to that described in the minimally invasive literature. Providers should educate all patients undergoing minimally invasive sacrocolpopexy as to self-catheterization techniques given the inability to identify preoperative risk factors.
