Long-term Outcomes With Macroplastique in Women With Stress Urinary Incontinence Secondary to Intrinsic Sphincter Deficiency.

OBJECTIVE: To evaluate the long-term outcomes of polydimethylsiloxane (Macroplastique (MPQ)) in women with stress urinary incontinence (SUI) secondary to intrinsic sphincter deficiency (ISD) using validated questionnaires. METHODS: Following IRB approval, charts of non-neurogenic women with SUI secondary to ISD who underwent MPQ injection were reviewed from a prospectively maintained database. ISD was defined as positive stress test with a well-supported urethra and low Valsalva leak point pressure when available. Excluded were women with follow-up <5years. Baseline data included validated questionnaire scores (UDI-6 question 3 (0-3), VAS Quality of Life, Incontinence Impact Questionnaire (IIQ-7)) and urodynamic study findings. Patients were followed with same questionnaires and three-dimensional ultrasound evaluating volume/configuration of MPQ. All three-dimensional ultrasound measurements were performed by the same imaging team blinded to clinical outcomes. Outcomes were evaluated in four groups based on prior SUI treatment. Success was defined as UDI-6 question 3 score of 0-1 and not requiring additional anti-incontinence therapy at the last visit after the last MPQ injection. RESULTS: From April 2011-December 2016, 106 patients (median age 67) met study criteria. Median follow-up time was 7.4years. Median MPQ injected was 5 mL. Overall success was 43%, with 54% successful after one injection and 46% requiring ≥2 injections. Across all groups, patients had improvement in Quality of Life and IIQ-7 Question 7 (frustration). Among the failure group, 17% opted for a secondary autologous sling procedure. CONCLUSION: MPQ demonstrated long-term favorable outcomes in a subset of women with SUI secondary to ISD.

Fosfomycin Prevents Intravenous Antibiotic Therapy in Women With Recurrent Urinary Tract Infections: A Retrospective Review.

OBJECTIVES: The aim of this study was to evaluate the role of oral fosfomycin to prevent the use of intravenous (IV) antibiotic therapy in women with recurrent urinary tract infection (RUTI) complicated by antibiotic allergies and/or multidrug-resistant organisms. METHODS: After institutional review board approval, a retrospective review of women prescribed fosfomycin for RUTI at our institution was performed. Excluded were patients who did not take fosfomycin. Data collected included demographics, baseline voiding function/urological anatomic abnormalities, need for IV antibiotic therapy for RUTI, RUTI-related surgery, antibiotic allergies, and urine culture results before and after taking fosfomycin. Success was defined as no subsequent IV antibiotic use for RUTI management after fosfomycin within the study follow-up. Secondary outcomes included time to next UTI after fosfomycin, time to next extended-spectrum beta-lactamase UTI, factors predicting failure, urine culture results after fosfomycin, and need for surgical intervention. RESULTS: Between 2013 and 2019, 105 women met study criteria. At a median follow-up (including phone interviews) of 1.7 years (interquartile range, 0.3-5.8) after fosfomycin, the success rate was 74%. Twenty-seven patients had documented sterile urine cultures immediately after fosfomycin. Prior history of hospitalization for UTI and infection with resistant organisms were predictive of failure. After fosfomycin, 25 women underwent bladder electrofulguration, and 3 required cystectomy. CONCLUSIONS: Fosfomycin reduced the rate of IV antibiotic therapy in the management of RUTI in women with multidrug-resistant organisms and/or antibiotic allergies. Fosfomycin was less effective in those with prior hospitalization for UTI or infection with resistant organisms.

Durability of Macroplastique volume and configuration in women with stress urinary incontinence secondary to intrinsic sphincter deficiency: A retrospective review.

OBJECTIVES: To evaluate the durability of Macroplastique® (MPQ) volume and configuration in women with stress urinary incontinence (SUI) secondary to intrinsic sphincter deficiency (ISD) using serial three-dimensional ultrasound (3DUS) measurements. METHODS: Following Institutional Review Board approval, charts of women with SUI and ISD (defined based on leak point pressure; lateral imaging of urethral support without hypermobility) who underwent MPQ were reviewed from a prospectively maintained database. All had at least two serial transperineal 3DUS measurements with no MPQ or other bulking agent injection between measurements. 3DUS was performed using the Philips IU22 ultrasound system with endovaginal 3D 9-3V end-fire probe typically at 6-8 weeks post-injection and yearly thereafter. The same imaging team blinded to clinical outcomes evaluated volume and configuration (circumferential/symmetric or asymmetric) at each 3DUS. RESULTS: Between 2011 and 2019, 62 of 174 women met study criteria. Those with prior other bulking agent injection or having ≤1 3DUS follow-up were excluded. Seventy-one percent of patients had one injection, while the remainder had two or more (29%). Median time between first and second 3DUS was 12 months. The mean change in MPQ volume between the first and last 3DUS measurement was -0.2 cc (95% CI: -0.5 to 0.004; P = .054). A median of 5.0 cc were injected in each patient. Forty-seven women had symmetric MPQ at first 3DUS, of whom only five (11%) had a follow-up 3DUS showing asymmetric MPQ distribution. CONCLUSIONS: At mid-term follow-up, repeat transperineal 3DUS after MPQ injection revealed minimal change in volume and configuration in the urethral wall.

Prospective Evaluation of Daily and Weekly Urine pH Variations Along With Diet Intake in Postmenopausal Women With Recurrent Urinary Tract Infections.

OBJECTIVES: Acidic urine pH may be protective against recurrent urinary tract infections (RUTIs). After reviewing the literature, we primarily analyzed urine pH fluctuations and secondarily compared them with diet in older women with RUTIs. METHODS: After IRB approval, postmenopausal women with documented RUTIs were enrolled. Participants were given preformatted charts to record urinalysis reagent strips (Medimpex) findings 4 times per day and concomitant food/beverage intake (food diary). Urine cultures at baseline ensured no infection during measurement period. Nutrient content reported in food diaries was analyzed by an experienced registered dietitian and compared with parallel fluctuations in urine pH. RESULTS: Of 26 women with median age of 72 years (55-86 years), the first 3 days of diet and urine pH recordings found that 17 (65%) of 26 exhibited urine pH variation greater than 1 unit, with an overall median of 6 (5-9). Comparing dietary analysis and urine pH changes, beta-carotene (P = 0.017) and total dietary sugar intake (P = 0.036) were associated with a decrease in urine pH, whereas monounsaturated fatty acids (MFA, 22:1, P = 0.023) and protein (P = 0.028) were associated with an increase in urine pH. CONCLUSIONS: In this real-life, observational study, 65% of older women with RUTIs exhibited notable changes in urine pH, with decreased urine pH associated with nutrients found in orange and yellow vegetables and several major food groups. A longitudinal study is needed to determine if changing an individual's diet and/or adding supplements could decrease the urine pH, thus affecting the rate of RUTIs.

Macroplastique for women with stress urinary incontinence secondary to intrinsic sphincter deficiency.

OBJECTIVE: To evaluate the subjective and objective outcomes of MacroplastiqueR (MPQ) in women with stress urinary incontinence (SUI) secondary to intrinsic sphincter deficiency (ISD). MATERIALS AND METHODS: Following Institutional Review Board (IRB) approval, charts of non-neurogenic women with SUI secondary to ISD who underwent MPQ injection and had 6 months minimum follow-up were reviewed from a prospectively maintained database. Patients were divided into 3 groups: Naive (Group I), Prior Anti-Incontinence Surgery (Group II), and combined Prior Bulking Agent and Anti-Incontinence Surgery (Group III). Data collected included SUI self-report, Urogenital Distress Inventory (UDI-6) Question 3, and VAS Quality of Life (QoL) Questionnaire scores at baseline and in follow-up. Three-dimensional ultrasound (3DUS) evaluated volume/confi guration of MPQ. Success was defi ned after the last MPQ injection as a UDI-6 Question 3 score of 0 (dry) or 1, and no reoperation for SUI. RESULTS: From 2011-2017, 106 of 142 women met study criteria. At a median follow-up of 20 months (mean=26 months; range: 6-71), success rate was 41% for Group I, 40% for Group II, and 65% for Group III (p = 0.22). QoL scores were signifi cantly improved over baseline in all groups. There was no signifi cant difference in clinical outcome between the asymmetrical and symmetrical group on 3DUS. The completely dry rate was highest in Group III at 29%, compared to 4% for Group I and 15% for Group II (p = 0.05). CONCLUSION: MacroplastiqueR improved subjective and objective outcome measures for SUI secondary to ISD as both a primary and secondary treatment option in women.
