Methenamine hippurate compared with trimethoprim for the prevention of recurrent urinary tract infections: a randomized clinical trial.

INTRODUCTION AND HYPOTHESIS: The objective was to find an alternative treatment to a low-dose antibiotic for the prevention of recurrent urinary tract infections (UTI) and to evaluate the difference in rates of reinfection within 1 year when treated with methenamine hippurate for prophylaxis compared with trimethoprim. METHODS: We present a non-blinded randomized trial comparing methenamine hippurate with trimethoprim for the prevention of recurrent UTI at 12 months after starting treatment. Women over 18 who had at least two culture-positive UTI in the prior 6 months or three in the prior year were included. Ninety-two patients met enrollment criteria and were randomized to receive daily prophylaxis with methenamine hippurate or trimethoprim for a minimum of 6 months. Both intent-to-treat and per-protocol analyses if patients received the alternative drug after randomization were analyzed using Student's t test, Mann-Whitney U test, Kaplan-Meier curves, log-rank test, and a logistic and multivariate regression model. The primary outcome of this study was culture-proven UTI recurrence by 12 months after initiating prophylaxis. RESULTS: In the intent-to-treat analysis, we found no difference between groups in recurrent UTI, with a 65% (28 out of 43) recurrence in the trimethoprim group versus 65% (28 out of 43) in the methenamine hippurate group (p = 1.00). In the per-protocol analysis, 65% (26 out of 40) versus 65% (30 out of 46) of patients had UTI recurrences in the trimethoprim group versus the methenamine hippurate group (p = 0.98). CONCLUSIONS: Methenamine hippurate may be an alternative for the prevention of recurrent UTI, with similar rates of recurrence and adverse effects to trimethoprim.

A Comparison of Sacrospinous Hysteropexy Augmented With Polypropylene Mesh Versus Human Dermis at 12-Month Follow-up: An Ambidirectional Study.

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%.

Cognitive changes in women starting anticholinergic medications for overactive bladder: a prospective study.

INTRODUCTION AND HYPOTHESIS: To assess cognitive changes in women 12 months after starting anticholinergic medications for overactive bladder syndrome (OAB). METHODS: We present a prospective cohort study assessing changes in cognition in women seen in a referral urogynecology practice. We compared women who started anticholinergic OAB medications with women not on anticholinergic OAB medications. The primary outcome was change over time on the Montreal Cognitive Assessment (MOCA) screening score. At enrollment, women completed a baseline MOCA screening, a Geriatric Depression Screen (GDS), and an assessment of medications to create an anticholinergic burden score (ACB). At 3, 6, 9, and 12 months after enrollment women were administered the MOCA, GDS, and a review of their medications and medical problems. Statistical analysis was performed using a linear mixed effects model taking into account correlated error terms given multiple MOCA assessments at various time points per patient. RESULTS: A total of 106 women were enrolled, 60 in the OAB medication group and 46 in the control (non-OAB medication) group. The mean age was 77 years, 93% of women were Caucasian, and 98% completed high school, with no difference between groups. Over time there was no difference in change of MOCA score between the OAB and control groups when controlling for age, GDS score, and ACB score (p = 0.78). This association did not change when women with a neurological diagnosis were excluded (n = 6). On average MOCA scores for the OAB group increased by 0.76 over 12 months and the control group increased 0.39, with no difference between the groups (p = 0.53). CONCLUSIONS: We found no changes in MOCA scores between OAB medication and control groups after controlling for age, depression, and polypharmacy after 12 months of follow-up.

Anterior Colporrhaphy With and Without Dermal Allograft: A Randomized Control Trial With Long-Term Follow-Up.

OBJECTIVE: The objective of this study was to determine whether anterior colporrhaphy plus insertion of anterior dermal allograft reduces anterior prolapse recurrence at 1 and 7 to 10 years postoperatively compared with anterior colporrhaphy alone. METHODS: We present a nonblinded randomized controlled trial with 1- and 7- to 10-year follow-up. Subjects were randomized between 2005 and 2008 to anterior colporrhaphy or ultralateral anterior colporrhaphy plus insertion of a dermal allograft spanning the anterior compartment between the arcus tendineus fascia pelvis on each side. Eligible subjects had anterior prolapse to the hymen or beyond, were bothered by their prolapse, and were planning to undergo surgical correction. Subjects completed a pelvic organ prolapse quantification system (POPQ) examination and Pelvic Floor Distress Inventory (PFDI)/PFDI-20 before surgery; a POPQ, PFDI, and Pelvic Organ Prolapse/Incontinence Sexual Questionnaire at 1 year postoperatively; and a POPQ, PFDI-20, Pelvic Organ Prolapse/Incontinence Sexual Questionnaire, Revised, and Patient-reported Global Impression of Improvement Inventory at 7 to 10 years postoperatively. Our primary outcome was anatomic anterior prolapse recurrence at 1 or 7 to 10 years defined as Aa or Ba greater than or equal to -1. Our secondary outcome was a composite score of anterior prolapse recurrence at 1 or 7 to 10 years defined as anatomic recurrence (Aa or Ba ≥ 0), retreatment for cystocele, or answering yes to PFDI-20 question 3 (subjective report of vaginal bulge). RESULTS: A total of 114 subjects were randomized, 70 to anterior colporrhaphy and 44 to anterior colporrhaphy plus dermal allograft. About 92% of subjects underwent concomitant apical suspension, 98% in the graft group and 89% in the nongraft group. Eighty-nine subjects (32 graft [73%], 57 nongraft [81%]) returned for 1-year follow-up. Fifty-three patients (19 graft [48%], 34 nongraft [49%]) returned for 7- to 10-year follow-up. The primary outcome was met by 8 (18%) graft and 22 (31%) nongraft subjects at 1 year postoperatively (P = 0.26) and by 10 (23%) graft and 24 (34%) nongraft subjects at 7 to 10 years postoperatively (P = 0.37). The secondary outcome was met by 8 (18%) graft and 15 (21%) nongraft subjects at 1 year postoperatively (P = 0.74) and by 13 (30%) graft and 21 (30.0%) nongraft subjects at 7 to 10 years postoperatively (P = 0.99). CONCLUSIONS: We cannot conclude whether there is a difference in anterior recurrence for anterior colporrhaphy with and without dermal allograft and do not recommend changes in clinical practice based on these results.

Subjective and objective responses to PTNS and predictors for success: a retrospective cohort study of percutaneous tibial nerve stimulation for overactive bladder.

INTRODUCTION AND HYPOTHESIS: We investigated the objective improvements in overactive bladder (OAB) symptoms in patients undergoing percutaneous tibial nerve stimulation (PTNS) and predictive factors of patient satisfaction. METHODS: In this single-center retrospective cohort study at a tertiary urogynecology center, we identified all female patients who underwent PTNS therapy from 1 October 2007 - 1 January 2016 and followed them from their initial visit through medication therapy and PTNS treatments. Patients who tried at least one medication prior to starting PTNS therapy and completed at least one PTNS visit were included. Baseline demographic data, urinary data, and details of medication and PTNS therapy sessions were collected from records through chart review. Paired or two-sample t-tests were used to compare changes over time or groups. Bivariate and multivariable logistic regression were performed. RESULTS: Two hundred thirteen patients underwent PTNS therapy and 183 patients met the criteria. Overall patients were able to decrease voiding frequency by 1 h, decrease nocturia episodes by 0.8, and decrease urge incontinence episodes with PTNS therapy by ten episodes per week (p = 0.02). Patients who continued OAB medications did not have additional improvements compared with patients who did not continue OAB medications during PTNS. Overall, 25.4% (43/169) patients reported ≥ 75% improvement during PTNS therapy, and 61.5% (104/169) reported ≥ 50% improvement. When evaluating predictive factors of ≥ 50% overall improvement, the number of PTNS sessions increased odds of subjective success (OR = 1.8, p = 0.004). Other factors were not significant predictors of subjective PTNS success. CONCLUSIONS: PTNS can provide both objective and subjective improvements for patients who do not respond to OAB medication therapy.

Which bladder instillations are more effective? DMSO vs. bupivacaine/heparin/triamcinolone: a retrospective study.

INTRODUCTION AND HYPOTHESIS: Bladder pain syndrome/interstitial cystitis (BPS/IC) is a chronic and debilitating condition. Our objective was to compare two different bladder instillation treatments in patients with BPS/IC: dimethyl sulfoxide with triamcinolone (DMSO) vs. bupivacaine with heparin and triamcinolone (B/H/T). Our hypothesis was that both treatments are equally effective. METHODS: A retrospective cohort study of instillation-naïve patients was conducted comparing responses to either DMSO or B/H/T at our tertiary urogynecology center from 2012 to 2014. The primary outcome was patient-reported percent of overall improvement from baseline. Secondary outcomes were change in patient-reported daytime voiding frequency (hours) and change in number of nighttime voiding episodes. Variables analyzed as potential confounders included pelvic pain, cystoscopy findings, levator spasm, and fibromyalgia. The two-sided Student's t test, chi-squared test, Poisson regression, and repeated-measure analysis of variance (ANOVA) were used for analyses. RESULTS: One hundred and ninety-three eligible patients were identified (45 receiving DMSO, 146 receiving B/H/T). Compared with baseline, DMSO patients reported 63% improvement (p < 0.0001), increased time between daytime voids by 1.5 h (p < 0.00), and a 40% reduction in nocturia episodes (p < 0.00). B/H/T patients reported 51% improvement (p < 0.00), increased time between daytime voids by 1.4 h (p < 0.00), and an 8% reduction in nocturia episodes (p = 0.26). When comparing the two treatments, DMSO resulted in a greater percentage of overall improvement (p = 0.02) and a significant decrease in nocturia episodes when compared with B/H/T (p = 0.02). There was no significant difference between treatments for daytime voiding frequency (p = 0.50). CONCLUSION: Bladder instillations with DMSO or B/H/T provide overall symptomatic improvement and improved frequency and nocturia. DMSO appears to provide greater improvement in nocturia and overall.

Abdominal sacrocolpopexy and urinary incontinence: surgical planning based on urodynamics.

OBJECTIVE: The objective of the study was to evaluate the use of urodynamics to determine the need for incontinence surgery at the time of abdominal sacrocolpopexy (ASC). STUDY DESIGN: The records of 441 women undergoing ASC during 2005-2007 were reviewed. Group 1 consisted of 204 women (46.3%) with urodynamic stress incontinence (USI), including occult USI, who underwent incontinence surgery with ASC. Group 2 consisted of 237 women (53.7%) without USI who underwent ASC alone. Primary outcome measures were any complaint of postoperative incontinence (stress or urge) or new-onset urgency/frequency (UF). RESULTS: At a mean follow-up of 46.6 weeks, the overall rate of incontinence was low and similar for both groups (13.4% in group 1 and 13.3% in group 2 [P = .967]), as was new-onset UF: 18.6% in group 1 and 11.5% in group 2 (P = .195). CONCLUSION: Urodynamic evaluation appears to be useful in determining the need for incontinence surgery at the time of ASC.

Pelvic floor fitness using lay instructors.

OBJECTIVE: Typically, pelvic muscle training for women with pelvic floor disorders is provided by medical personnel. We sought to evaluate the feasibility and symptom improvement after a nonmedical pelvic muscle training class in a prospective cohort. METHODS: Study participants volunteered to participate in an 11-week pelvic fitness and education class taught by a lay instructor at five fitness classrooms in the Chicago area. Participation was limited to adult women who verbally indicated that their pelvic symptoms included a minimum of some urge urinary symptom. Standardized assessments were completed before class, at the end of class, and 1 year after completion of the classes. These assessments included the 12-item short-form, validated pelvic questionnaires (Urogenital Distress Inventory Short Form, Incontinence Impact Questionnaire Short Form, and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire), and self-reported goals selection and achievement. RESULTS: Eighty-seven of 102 participants provided before and after class data, and 76 also provided 1-year data. Participants had a mean age of 58 years and a mean body mass index of 26.3. Most (91%) were white, and 63% had at least completed college. After class improvements in Urogenital Distress Inventory Short Form bothersomeness ratings were noted for all items and maintained at 1 year for all but pain or discomfort. Significant quality-of-life and sexual function improvements were reported after class and at 1 year. The 12-item short-form responses documented improvements in six areas of general health. The most important self-selected goal was achieved in 71% after class and maintained by 67% at 1 year. CONCLUSION: Nonmedical pelvic fitness classes are promising for pelvic symptom improvement in self-selected participants. LEVEL OF EVIDENCE: II.
