RESUMO

INTRODUCTION AND HYPOTHESIS: The primary aim of this study was to compare the effect of bladder instillations using dimethyl sulfoxide (DMSO) with triamcinolone versus bupivacaine, triamcinolone, and heparin (BTH) in women with newly diagnosed interstitial cystitis/painful bladder syndrome. The primary outcome was improvement in symptoms measured using the O'Leary-Sant Interstitial Cystitis Symptoms Index (ICSI) score. Secondary comparisons included changes in urinary frequency, nocturia, and bladder capacity. MATERIALS AND METHODS: This was a prospective, randomized study. Patients with a recent diagnosis of interstitial cystitis/painful bladder syndrome (IC/PBS) were randomized 1:1 to treatment with either 6 weekly bladder instillations of DMSO with triamcinolone or BTH. During follow-up visits, patients completed the ICSI questionnaire, and bladder capacity was determined through the retrograde filling of the bladder. The χ2 test or Student's t test were used for data analysis. RESULTS: A total of 83 patients were randomized, and final analysis included 70 participants who completed the 6 weekly instillations (42 DMSO, 28 BTH). The groups were similar in baseline demographics and clinical characteristics, except for cystometric maximum capacity (DMSO 338.62± 139.44 mL, BTH 447.43 ± 180.38 mL, p = 0.01). In the DMSO group, 63% of patients had a greater than 29.5% reduction in total ICSI score versus 43% in the BTH group (p = 0.15). Nocturia and pain were significantly reduced in the DMSO group. There was a significant increase from baseline in bladder capacity for both groups. CONCLUSION: In women with newly diagnosed IC/PBS, bladder instillations with DMSO and triamcinolone provide greater improvement in pain and nocturia compared to BTH.

RESUMO

INTRODUCTION AND HYPOTHESIS: The objective of this narrative review is to describe changes in urethral function that occur during a woman's lifetime. Evaluation of urethral function includes measurements of urethral closure pressure, at rest and during stress, leak point pressure, and the detailed study of anatomical and histological changes of the urethral sphincteric mechanism. METHODS: A literature search in MEDLINE, PubMed, and relevant journals from 1960 until 2020 was performed for articles dealing with urethral function and the impact of aging, pregnancy, and childbirth, female hormones, and menopausal transition on the urethral sphincteric mechanism. Longitudinal and cross-sectional epidemiological surveys, studies on histological changes in urethral anatomy during aging, and urodynamic data obtained at different points in a woman's lifetime, during pregnancy, after childbirth, as well as the effects of female hormones on urethral sphincter function are reviewed. Relevant studies presenting objective data are analyzed and briefly summarized. RESULTS AND CONCLUSIONS: The findings lead one to conclude that a constitutional or genetic predisposition, aging, and senescence are the most prominent etiological factors in the development of urinary incontinence and other pelvic floor disorders. Vaginal childbirth dilates and may damage the compressed pelvic supportive tissues and is invariably associated with a decline in urethral sphincter function. Pregnancy, hormonal alterations, menopausal transition, weight gain, and obesity are at best of secondary influence on the pathology of lower urinary tract dysfunction. The decline of circulating estrogens during menopausal transition may play a role in the transition of fibroblasts to cellular senescence.

RESUMO

OBJECTIVES: To evaluate the safety and efficacy of the eCoin - a nickel-sized, primary battery-powered, neuromodulation device for the treatment of urgency urinary incontinence which is implanted in the lower leg in a 20-minute procedure under local anesthesia. A feasibility clinical trial was conducted and the results after 1 year of treatment with the eCoin are presented. METHODS: A total of 46 participants with refractory urgency urinary incontinence were included in this prospective, single-arm, open-label study. This study was conducted at 7 sites in the United States and New Zealand. Participants in this study were implanted with the eCoin in the lower leg over the tibial nerve and activated after 4 weeks. Bladder diary data and validated quality-of-life instruments, collected at 3, 6, and 12 months' post-activation, were compared to baseline values. RESULTS: Responders were defined as those who had a ≥50% reduction in reported episodes of urgency urinary incontinence. At 12 months', 65% of participants were considered responders with 26% of participants achieving complete continence. The median number of urgency urinary incontinence episodes per day decreased from 4.2 at baseline to 1.7 at 12 months'. Seventy percent of participants reported feeling "better", "much better", or "very much better" on the Likert 7-point maximum scale. One participant experienced a related serious adverse event. CONCLUSION: The eCoin is a safe and effective treatment for urgency urinary incontinence associated with overactive bladder syndrome, with significant reduction or complete resolution of symptoms and no significant safety concerns.

RESUMO

BACKGROUND: Suture-based hysteropexy is performed for pelvic organ prolapse with varying results. Graft augmentation may improve outcomes. OBJECTIVE: The aim of this study was to determine whether vaginal hysteropexy with mesh reduces recurrence at 1-year postoperative examination compared with hysteropexy with allograft. METHODS: Data were collected for patients who underwent vaginal hysteropexy with either mesh "Uphold" (referred to as "mesh") or a cadaveric allograft "Axis or Repliform" (referred to as "dermal"). The primary outcome was anatomic success defined as no prolapse Pelvic Organ Prolapse Quantification System stage II or less at 12 months postoperative. The secondary outcomes were recurrence to the hymen and a composite score (any positive response to the 20-item Pelvic Floor Distress Inventory question 3 and cervix ≥ -1/2 total vaginal length at rest or as reference point 3 cm proximal to or above the hymenal ring anteriorly [Ba] ≥0) measured at 12 months. RESULTS: Two hundred seventy-four patients returned for their 1-year postoperative examination: 93.5% of the mesh group (231/247 subjects) and 95.5% of the dermal group (43/45 subjects). The mesh group had fewer recurrences to or beyond Pelvic Organ Prolapse Quantification System stage II (mesh 18% vs dermal 29%, P = 0.03), to the hymen (2.6% vs 9.3%, P = 0.007), or based on composite score (19 vs 33%, P = 0.007). Questionnaire data improved more in the mesh group (P < 0.0001). The exposure rate was 5.75% (13/247) in the mesh group. Reoperation rate was greater in the dermal group (mesh 4.3%vs dermal 7.3%, P = 02). CONCLUSIONS: Hysteropexy augmented with mesh reduced the recurrence at 1 year compared with hysteropexy with allograft. Fewer patients in the mesh group felt a bulge at 1 year (4.5% vs 20.9%, P < 0.0001). These findings need to be weighed against the mesh exposure rate of 5.75%.

RESUMO

PURPOSE: We performed a clinical feasibility trial to evaluate the safety and efficacy of a fully implanted, primary battery powered, nickel sized and shaped neuromodulation device called the eCoin® for tibial nerve stimulation to treat refractory urgency urinary incontinence. MATERIALS AND METHODS: This prospective, single arm, open label study included 46 participants with refractory urgency urinary incontinence. It was performed at multiple sites in the United States and New Zealand. The device was implanted in the lower leg over the tibial nerve and activated after 4 weeks. Bladder diary data and validated quality of life instruments were collected 3 and 6 months after activation and compared to baseline values. RESULTS: The mean ± SD age of participants was 63.4 ± 11.5 years and 45 (98%) were female. Episodes of urgency urinary incontinence were reduced a relative median of 71% after 3 months of treatment (4.2 vs 1.7 daily episodes at 3 months, p = 0.001). A 50% or greater decrease in reported episodes of urgency urinary incontinence was observed in 32 of 46 participants (69.6%) at 3 months with more than 20% dry at 3 and 6 months. I-QOL (Incontinence Quality of Life) scores improved an average of 25.9 points and 33 of 46 patients (72%) indicated improvement in symptoms. A single serious adverse event secondary to wound care resolved with intravenous antibiotics. CONCLUSIONS: The implantable neuromodulation device was a safe and effective treatment of urgency urinary incontinence associated with overactive bladder syndrome with a significant reduction or resolution of symptoms and no significant safety concerns.

RESUMO

OBJECTIVES: This study aimed to determine the relationship between patient satisfaction with overactive bladder syndrome (OAB) pharmacotherapy and persistence rates. We compared persistence rates between satisfied and dissatisfied patients at designated study intervals. METHODS: This was a retrospective cohort study of new patients who initiated OAB medication. Patients were classified as either satisfied or dissatisfied on the basis of a single-item treatment satisfaction question. Persistence was defined as continuous days on therapy. The measured rate of persistence was determined as the ratio of patients who persisted on medication at 4, 12, and 24 weeks. Data collection included demographic and prescription information; urinary symptom parameters, symptom and quality-of-life scales, and patient-reported outcomes. Two-sample t test or Wilcoxon rank sum test was used to compare continuous outcomes between both groups (satisfied vs not satisfied). χ Test or Fisher exact test was used to compare categorical outcomes between groups. RESULTS: We analyzed the first 116 charts that met our inclusion criteria. Satisfied and dissatisfied patients did not differ in demographic variables. Satisfied patients had a median of 461 vs 254 persistent days (P = 0.0001). Satisfied patients (12.5% vs 40%) were less likely to discontinue medication (P = 0.0068). The discontinuation-free distribution was significantly different between satisfied and dissatisfied cohorts, favoring those who reported satisfaction with OAB medication at all time points (P < 0.0001). Patients who totally discontinued pharmacotherapy were 7 times more likely to be dissatisfied (odds ratio, 7.0; P = 0.002). CONCLUSIONS: Our study helps clarify the relationship between persistence on OAB medication and treatment satisfaction. We found that persistence could serve as a surrogate marker for patient satisfaction because those who reported being satisfied were more likely to persist on therapy at all study intervals.

RESUMO

INTRODUCTION AND HYPOTHESIS: We compared persistence on overactive bladder (OAB) pharmacotherapy in patients treated in the Female Pelvic Medicine and Reconstructive Surgery (FPMRS) department compared with patients treated in the Internal Medicine (IM) and General Urology (GU) departments within an integrated health-care system. We hypothesized that persistence would be higher among FPMRS patients. METHODS: This was a retrospective cohort study. Patients with at least one prescription for OAB between January 2003 and July 2014 were identified. Demographic, prescription and treatment specialty data and data on the use of third-line therapies were collected. The primary outcome was persistence, defined as days on continuous pharmacotherapy. Discontinuation was defined as a treatment gap of ≥45 days. Discontinuation-free probabilities were calculated using the Kaplan-Meier method and compared among the specialties. Predictors of persistence were estimated using logistic regression with adjustment for covariates. Pearson correlation coefficients were calculated to identify risk associations. RESULTS: A total of 252 subjects were identified. At 12 weeks, 6 months and 1 year, FPMRS patients had the highest persistence rates of 93 %, 87 % and 79 % in contrast to 72 %, 68 % and 50 % in GU patients, and 83 %, 71 % and 63 % in IM patients (p = 0.006, p = 0.007, p = 0.001, respectively). The median persistence in FPMRS patients was 738 days, in GU patients 313 days and in IM patients 486 days (p = 0.006). Of the FPMRS patients, 61 % switched to at least a second medication, as compared to 27 % of IM patients and 14 % of GU patients (p < 0.0001). CONCLUSIONS: Persistence on OAB pharmacotherapy was higher among FPMRS patients than among GU and IM patients in this community setting. These results suggest that persistence is higher under subspecialist supervision.

RESUMO

INTRODUCTION AND HYPOTHESIS: To assess the prevalence of vesico-ureteral reflux (VUR) and upper urinary tract damage in women with idiopathic high-pressure detrusor overactivity (IHPDO) and to characterize their bladder function. METHODS: A retrospective chart review of women diagnosed with IHPDO (detrusor pressures > 40 cm H2O during involuntary bladder contractions) from 2007 to 2010 was conducted. Women were assessed for VUR by X-ray voiding cysto-urethrogram. Renal ultrasound or CT urogram, serum BUN/creatinine, and urinalyses were performed if reflux reached the renal pelvices. Cystometric and voiding pressure study data were reviewed for detrusor overactivity pressure and volume, voiding dysfunction, urethral relaxation, compliance, and bladder outlet obstruction. RESULTS: Sixty-five women were diagnosed with IHPDO, and 50 completed an X-ray voiding cysto-urethrogram. The median (range) detrusor overactivity pressure was 65 (41-251) cm H2O. Four (8.0%) women had IHPDO; none had upper urinary tract deterioration. The majority of women exhibited urethral relaxation with voiding, impaired compliance, and bladder outlet obstruction. CONCLUSIONS: Women with IHPDO are at risk of low-grade vesico-ureteral reflux. However, most women with IHPDO are likely protected from reflux by intermittent exposure to high detrusor pressures and the ability to decompress the bladder by urethral relaxation.

RESUMO

INTRODUCTION AND HYPOTHESIS: Stress urinary incontinence (SUI) is a common and growing problem among adult women and affects individuals and society through decreased quality of life (QoL), decreased work productivity, and increased health care costs. A new, nonsurgical treatment option has become available for women who have failed conservative therapy, but its cost effectiveness has not been evaluated. This study examined the cost effectiveness of transurethral radiofrequency microremodeling of the female bladder neck and proximal urethra compared with synthetic transobturator tape (TOT), retropubic transvaginal tape (TVT) sling, and Burch colposuspension surgeries for treating SUI. METHODS: A Markov model was used to compare the cost effectiveness of five strategies for treating SUI for patients who had previously failed conservative therapy. The strategies were designed to compare the value of starting with a less invasive treatment. The cost-effectiveness analysis was conducted from the health care system perspective. Efficacy and adverse event rates were obtained from the literature; reimbursement costs were based on Medicare fee schedule. The model cycle was 3 months, with a 3-year time horizon. Single-variable sensitivity analyses were conducted to assess stability of base-case results. RESULTS: Two of the five strategies employed the use of transurethral radiofrequency microremodeling and achieved 17-30 % lower mean costs relative to their comparative sling or Burch strategies. CONCLUSIONS: Superior safety and cost effectiveness are recognized when patients are offered a sequential approach to SUI management that employs transurethral radiofrequency microremodeling before invasive surgical procedures. This sequential approach is consistent with treatment strategies for other conditions and offers a solution for women with SUI who want to avoid the inherent risks and costs of invasive continence surgery.

RESUMO

INTRODUCTION AND HYPOTHESIS: The purpose of this study was to investigate change in bladder capacity as a measure of response to combined intravesical dimethyl sulfoxide (DMSO) and triamcinolone instillations for the treatment of newly diagnosed bladder pain syndrome/interstitial cystitis (BPS/IC). METHODS: 141 newly diagnosed women were identified retrospectively. 79 were treated with weekly DMSO/triamcinolone instillations. Change in bladder capacity with bladder retrofill, daytime urinary frequency, nocturia episodes per night, and Likert scale symptom scores were reviewed. Wilcoxon signed-rank tests, Wilcoxon rank-sum tests, Spearman's rank correlations, COX regression analysis, and a Kaplan-Meier survival curve were performed. RESULTS: Significant changes (median (25(th)-percentile to 75(th)-percentile) were noted for bladder capacity (75 mL (25 to 130 mL), p < 0.0001), inter-void interval (0 hrs (0 to 1 hour), p < 0.0001), nocturia episodes per night (-1 (-2 to 0), p < 0.0001), and aggregate Likert symptom scores (-2 points (-5 to 0), p < 0.0001). Percent change in bladder capacity correlated positively with percent change in inter-void interval (p = 0.03) and negatively with percent changes in nocturia (p = 0.17) and symptom scores (p = 0.01). Women without detrusor overactivity (DO) had greater percent changes in capacity than women with DO (62.5 % vs. 16.5 %, p = 0.02). 61.3 % of patients were retreated with a 36 weeks median time to retreatment and no difference in time to retreatment based upon DO. Greater capacity was protective against retreatment (hazard ratio = 0.997 [95 % CI 0.994,0.999], p = 0.02). CONCLUSIONS: Percent change in bladder capacity is a useful objective measure of response to intravesical DMSO/triamcinolone for newly diagnosed BPS/IC. Clinical outcomes do not differ based upon presence of DO.

RESUMO

INTRODUCTION AND HYPOTHESIS: Reconstructive pelvic surgery outcome is closely related to the vaginal and pelvic wound healing processes. Transforming growth factor beta 1 (TGF-ß1) is a principal mediator of wound repair in dermal tissue. We sought to assess this factor's expression in vaginal and dermal surgical wound repair in the rabbit. METHODS: We excised bilateral 6-mm full-thickness circular segments from the abdominal skin and vagina in 36 New Zealand White (NZW) nulliparous female rabbits. Animals were sacrificed before, on the day of, and 4, 7, 10, 14, 21, 28, and 35 days after tissue wounding, and their wounds were assessed for surface area and TGF-ß1 gene transcription by real-time polymerase chain reaction (PCR). RESULTS: In both the abdominal skin and vagina, TGF-ß1 gene transcription increased immediately after tissue injury, reaching maximal levels on days 4-7, and decreased shortly thereafter, attaining minimal values on day 35. A significant correlation between TGF-ß1 expression and the wound's closure rate was found in both tissues. CONCLUSIONS: TGF-ß1 gene transcription significantly correlates with the surgical vaginal and dermal wound closure rate, implying that this factor is involved in the process of wound repair in both tissues.

RESUMO

UNLABELLED: INTODUCTION AND HYPOTHESIS: The vaginal wound healing process is a major determinant of surgical outcome following pelvic reconstructive surgery. Since the majority of these surgeries are performed in peri- and postmenopausal women, it is essential to understand how estrogen deficiency affects this process. We aimed to histologically evaluate the vaginal incisional wound healing process in a rabbit menopause model. METHODS: Sixty three rabbits were utilized and divided into 3 groups: Twenty one underwent bilateral oophorectomy, 21 underwent a sham surgery, and 21 served as controls. Eight weeks later, standardized full-thickness 6 mm circular segments were excised from the vagina of all rabbits and spontaneous healing was recorded. Animals were euthanized sequentially, before wounding, and at 0, 4, 7, 14, 21 and 35 days after wounding, and their wounds were harvested and assessed histologically for wound healing using a validated scoring system. RESULTS: Oophorectomized rabbits showed significantly delayed wound closure (p < 0.02), neovascularization (p < 0.01), granulation tissue accumulation and maturation (p < 0.02), collagen deposition (p < 0.01) and re-epithelialization (p < 0.01), however acute and chronic inflammation were significantly enhanced (p < 0.02). CONCLUSION: Oophorectomized rabbits show protracted incisional vaginal wound healing by all histologic criteria, however, inflammation is significantly enhanced.

RESUMO

OBJECTIVE: The outcome of pelvic reconstructive surgery is largely dependent on the vaginal wound healing process, but this process has not yet been fully elucidated. Platelet-derived growth factor (PDGF) is an important mediator of the wound healing process in cutaneous tissue. We sought to compare PDGF-B mRNA expression in vaginal versus cutaneous incisional wound healing in a rabbit model. STUDY DESIGN: Bilateral 6 mm full-thickness circular segments were excised from the vagina and abdominal skin in 36 New Zealand-White female rabbits. Animals were euthanized sequentially before, on the day of and 4, 7, 10, 14, 21, 28 and 35 days after wounding. Their wounds were evaluated for surface area and PDGF-B mRNA expression using real time PCR. RESULTS: In both tissues PDGF-B mRNA expression increased constantly after wounding, reaching peak levels on day 10, and declined immediately thereafter, reaching minimal values on day 21. In both tissues, the expression of PDGF-B mRNA significantly correlated with the wound closure rate. CONCLUSION: PDGF-B mRNA expression significantly correlates with incisional vaginal and cutaneous wound closure, suggesting that this factor plays an important role in the wound healing process of both tissues.

RESUMO

BACKGROUND: Foreign-body granuloma is a potential complication of periurethral injection of calcium hydroxylapatite for the treatment of type III stress urinary incontinence. CASES: We present two cases of foreign-body granuloma formation after periurethral injection of calcium hydroxylapatite for type III stress urinary incontinence. Excision of the lesion resulted in cessation of pain in a symptomatic patient; however, it led to the resumption of stress urinary incontinence in both cases. CONCLUSION: Foreign-body granuloma is not the normative response to periurethral bulking with calcium hydroxylapatite. However, granuloma should be considered when a periurethral mass is encountered after injection of calcium hydroxylapatite for type III stress urinary incontinence.

RESUMO

We aimed to assess the effect of bilateral oophorectomy on vaginal wound healing in three groups of New Zealand White rabbits (24 rabbits each). Group 1 underwent bilateral oophorectomy, group 2 underwent a sham surgery, and group 3 served as control. Standardized vaginal tissue specimens were harvested and assessed for wound and scar surface area and tensiometric analysis before wounding, and sequentially thereafter, showing that vaginal wound closure, scar contraction, and recovery of biomechanical properties are significantly slower in oophorectomized rabbits.

RESUMO

INTRODUCTION AND HYPOTHESIS: A terminology and standardized classification has yet to be developed for those complications arising directly from the insertion of synthetic (prostheses) and biological (grafts) materials in female pelvic floor surgery. METHODS: This report on the above terminology and classification combines the input of members of the Standardization and Terminology Committees of two International Organizations, the International Urogynecological Association (IUGA) and the International Continence Society (ICS) and a Joint IUGA/ICS Working Group on Complications Terminology, assisted at intervals by many expert external referees. An extensive process of 11 rounds of internal and external review took place with exhaustive examination of each aspect of the terminology and classification. Decision-making was by collective opinion (consensus). RESULTS: A terminology and classification of complications related directly to the insertion of prostheses and grafts in female pelvic floor surgery has been developed, with the classification based on category (C), time (T) and site (S) classes and divisions, that should encompass all conceivable scenarios for describing insertion complications and healing abnormalities. The CTS code for each complication, involving three (or four) letters and three numerals, is likely to be very suitable for any surgical audit or registry, particularly one that is procedure-specific. Users of the classification have been assisted by case examples, colour charts and online aids (www.icsoffice.org/complication). CONCLUSION: A consensus-based terminology and classification report for prosthesis and grafts complications in female pelvic floor surgery has been produced, aimed at being a significant aid to clinical practice and research.

RESUMO

INTRODUCTION AND HYPOTHESIS: a terminology and standardized classification has yet to be developed for those complications arising directly from the insertion of synthetic (prostheses) and biological (grafts) materials in female pelvic floor surgery. METHODS: this report on the above terminology and classification combines the input of members of the Standardization and Terminology Committees of two International Organizations, the International Urogynecological Association (IUGA) and the International Continence Society (ICS) and a Joint IUGA/ICS Working Group on Complications Terminology, assisted at intervals by many expert external referees. An extensive process of 11 rounds of internal and external review took place with exhaustive examination of each aspect of the terminology and classification. Decision-making was by collective opinion (consensus). RESULTS: a terminology and classification of complications related directly to the insertion of prostheses and grafts in female pelvic floor surgery has been developed, with the classification based on category (C), time (T) and site (S) classes and divisions, that should encompass all conceivable scenarios for describing insertion complications and healing abnormalities. The CTS code for each complication, involving three (or four) letters and three numerals, is likely to be very suitable for any surgical audit or registry, particularly one that is procedure-specific. Users of the classification have been assisted by case examples, colour charts and online aids ( www.icsoffice.org/complication ). CONCLUSIONS: a consensus-based terminology and classification report for prosthess and grafts complications in female pelvic floor surgery has been produced, aimed at being a significant aid to clinical practice and research.

RESUMO

Interstitial cystitis/painful bladder syndrome (IC/PBS) is a chronic bladder disorder characterized by pelvic pain and irritative voiding symptoms. The symptoms of IC/PBS can overlap with such conditions as endometriosis, recurrent urinary tract infection, chronic pelvic pain, overactive bladder, and vulvodynia. The etiology of IC/PBS is likely multifactorial and may involve a defective urothelium, neurogenic upregulation, and mast cell activation. A thorough patient history and physical examination are critical in the differential diagnosis of IC/PBS. Frequent follow-up and patient education are important components of treatment once a condition is diagnosed. A multimodal approach to therapy can provide optimal relief for patients with IC/PBS.

RESUMO

OBJECTIVES: : To test the validity and reliability of a modified short-form Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-9) in a general female population. METHODS: : A cross-sectional survey of 364 sexually active women attending annual gatherings in 2005-06 was conducted. Validated questionnaires were completed, including PISQ-12, Index of Female Sexual Function (IFSF), Pelvic Floor Distress Inventory-20 (PFDI-20), Beck Depression Inventory Second Edition (BDI-II) and Pelvic Pain Urgency/Frequency (PUF) scale. PISQ-12/PISQ-9 scores, for construct validity, were compared with the validated questionnaires, and reliability was assessed with Cronbach's alpha statistic. RESULTS: : PISQ-12/PISQ-9 scores correlated significantly with IFSF scores (Spearman-coefficient, 0.65 and 0.66, respectively, P < 0.0001). Mean PISQ-12/PISQ-9 scores in asymptomatic women were significantly better than those in symptomatic women (PISQ-12: 40.0 ± 4.3 versus 37.1 ± 5.2, P < 0.0001; effect size = 0.65, PISQ-9: 28.1 ± 4.1 versus 25.8 ± 4.8, P < 0.0001, effect size = 0.56). PISQ-12/PISQ-9 scores were worse in women with depressive/bladder-pain symptoms compared with those women without these symptoms. Cronbach's alpha values were 0.73 and 0.72 for PISQ-12 and PISQ-9 scores, respectively. CONCLUSIONS: : PISQ-9 scores strongly correlate with PISQ-12 scores as well as scores of a general sexual-function questionnaire and Cronbach's alpha statistics are acceptable. The PISQ-9 can be reliably used in comparative studies assessing pelvic floor function in women with and without prolapse or incontinence.

RESUMO

INTRODUCTION AND HYPOTHESIS: The aim of this study is to compare acellular dermal matrix to standard colporrhaphy for cystocele repair. METHODS: One hundred two patients with greater than or equal to stage II anterior prolapse (Aa or Ba 0) who underwent anterior colporrhaphy with acellular dermal implant attached to the arcus between October 2003 and February 2007 were compared to 89 controls who received standard anterior colporrhaphy. Objective recurrence was defined as greater than or equal to stage II (Aa or Ba -1). RESULTS: The dermal graft and colporrhaphy groups were comparable in age, parity, body mass index, and concomitant surgeries except hysteropexy and hysterectomy. Regression was performed for possible confounders. Postoperatively, 14 (19%) recurrences were identified in the dermal graft group vs. 26 (43%) in the colporrhaphy group (p = 0.004). Two patients underwent reoperations for cystocele recurrence in the study group vs. four in the control group. Time to normal voiding, subjective stress urinary incontinence, estimated blood loss, and length of hospital stay did not differ between groups. CONCLUSION: Dermal acellular matrix provides benefit over standard colporrhaphy.
