RESUMO
INTRODUCTION: To quantify and compare recurrent urinary tract infection costs between 1 year before and 1 year after electrofulguration. METHODS: Following IRB approval, a well-characterized cohort of non-neurogenic women with >3 symptomatic urinary tract infections (UTIs)/year, a negative upper and lower urinary tract evaluation, and inflammatory bladder lesions (cystitis) on office cystoscopy who underwent fulguration of these lesions was analyzed. Cost of visits, imaging, labs, and medications were summed for 1-year pre- and post-fulguration using the Medicare Physician Fee Schedule, local pharmacy pricing, and institutional expenses. Before fulguration, all patients underwent clinic visit, noninvasive flow study, and flexible cystoscopy, and post-fulguration, 6-week follow-up visit and 6-month cystoscopy. RESULTS: Ninety-three women met study criteria (mean age 64), with 100% 1-year follow-up. Before fulguration, 73% of patients used daily antibiotic suppression, 6% self-start antibiotics, and 5% postcoital prophylaxis. Some also used vaginal estrogens (17%), urinary analgesics (13%), and cranberry or d-mannose supplements (7%). At 1 year post-fulguration, 82% had 0-1 infections and no cystoscopy evidence of cystitis, while 14% required additional fulguration for new cystitis sites and recurrent infections. Patients had on average 0.7 infections in the 1-year post-fulguration, which was significantly lower than pre-fulguration (p < 0.05). Mean 1-year pre-fulguration cost was $1328 (median $1071, range $291-$5564). Mean 1-year post-fulguration cost was $617 (median $467, range $275-$4580). On average, post-fulguration costs were $710 lower than pre-EF (p < 0.05). CONCLUSION: For women with antibiotic-refractory recurrent urinary tract infections and cystoscopy evidence of cystitis, fulguration was associated with a significant reduction in UTI-related costs in the 1-year post-fulguration.
RESUMO
Background: Antibiotic-recalcitrant recurrent urinary tract infection (rUTI) is has become increasingly observed in postmenopausal women. Therefore, when standard antibiotic therapies have failed, some elect electrofulguration (EF) of areas of chronic cystitis when detected on office cystoscopy. EF is thought to remove tissue-resident bacteria that have been previously detected in the bladder walls of postmenopausal women with rUTI. We hypothesized that increased bladder bacterial burden may be associated with incomplete rUTI resolution following EF. Methods: Following IRB approval, bladder biopsies were obtained from 34 consenting menopausal women electing EF for the advanced management of rUTI. 16S rRNA FISH was performed using both universal and Escherichia probes and tissue-resident bacterial load was quantified. Time to UTI relapse after EF was recorded during a six-month follow-up period and the association of bladder bacterial burden and clinical covariates with UTI relapse was assessed. Results: We observed bladder-resident Escherichia in 52% of all participants and in 92% of participants with recent E. coli UTI. Time-to-relapse analysis revealed that women with high bladder bacterial burden as detected by the universal probe had a significantly ( p =0.035) higher risk of UTI within six months of EF (HR=3.15, 95% CI: 1.09-9.11). Interestingly, bladder-resident Escherichia was not significantly associated ( p =0.26) with a higher risk of UTI relapse (HR= 2.14, 95% CI: 0.58-7.90). Conclusions: We observed that total bladder bacterial burden was associated with a 3.1x increased risk of rUTI relapse within six months. Continued analysis of the relationship between bladder bacterial burden and rUTI outcomes may provide insight into the management of these challenging patients.
RESUMO
Electrofulguration (EF) of areas of chronic cystitis in women with antibiotic-recalcitrant recurrent urinary tract infections (RUTIs) can result in improvement of their urinary tract infections (UTIs). We compared urine culture (UC) findings in patients before and after EF, as well as how they vary with cystitis stage at the time of EF, to evaluate for persistent species. After obtaining institutional review board approval, we retrospectively reviewed a prospectively maintained database of EF patients for those with positive UC findings in the 3-6 months preceding EF. Patient pre-EF UC was then compared with first positive UC after EF prompted by a new symptomatic UTI episode, with the hypothesis that the same species will be identified before and after EF. Exclusion criteria included UC from outside institution, neurogenic bladder, and need for catheterization. Ninety-nine women with pre- or post-EF UC-recorded organisms met the study criteria. The median age was 65 years (interquartile range 64-74), with a median time to first positive culture following fulguration of 9.7 months. For 26 patients with positive cultures both pre- and post-EF, the same organism was present in both cultures in 73% of the patients, with predominantly Escherichia coli. EF was effective at reducing the rate of UTIs in this population. For women undergoing EF for antibiotic-recalcitrant RUTIs and associated chronic cystitis lesions, 73% of those with a UC obtained at the time of a first symptomatic recurrent UTI episode post-EF expressed the same organism as before EF. Further study is needed to better understand the evolution of the microbiome post-EF.IMPORTANCEAmong women who experience a recurrent urinary tract infection after a fulguration procedure on areas of chronic cystitis in their bladder, there are no data available on whether the bacterial species found in urine cultures are the same or different from those present before fulguration. By removing the inflamed surface layer of cystitis during fulguration, it is possible that the procedure unmasks deep-seated bacteria. The bacterial kingdom in the bladder wall of these chronically infected women may be different from what is expressed sporadically in urine cultures. Confirming prior studies, we found that fulguration in women with antibiotic-recalcitrant recurrent urinary tract infections and cystitis lesions was effective at reducing the rate of urinary tract infections. At the time of a first symptomatic recurrent UTI episode post-fulguration, 73% expressed the same organism in urine culture as before fulguration. Further study is needed to better understand the evolution of the microbiome post-EF. This article evaluates persistent infections after electrofulguration of areas with chronic cystitis in post-menopausal women with antibiotic-recalcitrant recurrent urinary tract infections. Pre-fulguration urine cultures were compared with the first positive urine culture prompted by a new symptomatic UTI episode after electrofulguration, with the hypothesis that the same species will be identified before and after the fulguration procedure. Electrofulguration was effective at reducing the rate of UTIs in this population. However, 73% of those with a urine culture obtained at the time of a first symptomatic recurrent UTI episode post-electrofulguration expressed the same organism (predominantly Escherichia coli) as before the fulguration procedure. Further study is needed to better understand the evolution of the microbiome after electrofulguration.

INTRODUCTION AND OBJECTIVES: Relevant, meaningful, and achievable data points are critical in objectively assessing quality, utility, and outcomes in female stress urinary incontinence (SUI) surgery. A minimum data set female SUI surgery studies was proposed by the first American Urological Association guidelines on the surgical management of female SUI in 1997, but recommendation adherence has been suboptimal. The Female Stress Urinary Incontinence Surgical Publication Working Group (WG) was created from members of several prominent organizations to formulate a recommended standard of study structure, description, and minimum outcome data set to be utilized in designing and publishing future SUI studies. The goal of this WG was to create a body of evidence better able to assess the outcomes of female SUI surgery. METHODS: The WG reviewed the minimum data set proposed in the 1997 AUA SUI Guideline document, and other relevant literature. The body of literature was examined in the context of the profound changes in the field over the past 25 years. Through a DELPHI process, a standard study structure and minimum data set were generated. Care was taken to balance the value of several meaningful and relevant data points against the burden of creating an excessively difficult or restrictive standard that would disincentivize widespread adoption and negatively impact manuscript production and acceptance. RESULTS: The WG outlined standardization in four major areas: (1) study design, (2) pretreatment demographics and characterization of the study population, (3) intraoperative events, and (4) posttreatment evaluation, and complications. Forty-two items were evaluated and graded as: STANDARD-must be included; ADDITIONAL-may be included for a specific study and is inclusive of the Standard items; OPTIMAL-may be included for a comprehensive study and is inclusive of the Standard and Additional items; UNNECESSARY/LEGACY-not relevant. CONCLUSIONS: A reasonable, achievable, and clinically meaningful minimum data set has been constructed. A structured framework will allow future surgical interventions for female SUI to be objectively scrutinized and compared in a clinically significant manner. Ultimately, such a data set, if adopted by the academic community, will enhance the quality of the scientific literature, and ultimately improve short and long-term outcomes for female patients undergoing surgery to correct SUI.

RESUMO
PURPOSE: To review our 10-year experience with laser excision for urethral mesh erosion (UME) of mid-urethral slings (MUS). METHODS: Following Institutional Review Board approval, the charts of female patients with endoscopic laser excision of UME were retrospectively reviewed. Demographics, clinical presentation, surgical history, pre- and post-operative Urinary Distress Inventory-6 scores and quality of life ratings, operative reports, and outcomes were obtained from electronic medical records. UME cure was defined as no residual mesh on office cystourethroscopy 5-6 months after the final laser excision procedure. RESULTS: From 2011 to 2021, 23 patients met study criteria; median age was 56 (range 44-79) years. Twenty (87%) had multiple prior urogynecologic procedures. Median time from MUS placement to presentation with UME-related complaints was 5.3 [interquartile range (IQR) 2.3-7.6] years. The most common presenting symptom was recurrent urinary tract infection (rUTI) (n = 10). Median operating time was 49 (IQR 37-80) minutes. Median duration of follow-up was 24 (IQR 12-84) months. Fourteen (61%) required more than 1 laser excision procedure for UME. Although 5 were asymptomatic (22%), new (n = 5) or persistent (n = 8) urinary incontinence was the most common symptom on follow-up (57%). CONCLUSION: UME presenting symptoms are highly variable, necessitating a high index of suspicion in patients with a history of MUS, especially in the case of rUTI. Endoscopic laser excision is a minimally invasive, brief, safe, outpatient procedure with a high UME cure rate.

OBJECTIVE: To report a series of women with antibiotic-recalcitrant recurrent urinary tract infections (rUTI) managed with robotic simple cystectomy and ileal conduit urinary diversion. METHODS: Following Institutional Review Board approval, all female patients who underwent robotic cystectomy for rUTI between 2011 and 2021 were identified from a prospectively-maintained internal database at a tertiary care center. Exclusion criteria included interstitial cystitis, neurogenic bladder, urinary tract neoplasm, or congenital abnormality. Electronic medical records were reviewed by an independent researcher. Patients were also administered the Quality of Life Questionnaire-C30. RESULTS: Twenty-four patients met inclusion criteria. Median age was 75 years (range 53-87). Median rUTI duration was 6 (interquartile range [IQR] 2-10) years. Median urinary tract infections count in the 12-month preceding cystectomy was 5 (IQR 3-9). Infections with multidrug resistant organisms were found in 21 patients (88%). The 30-day postoperative complication rate was 79% (19/24), of which 11% were Clavien-Dindo grade ≥III. The main late complication was parastomal hernia, with 17% requiring repair or revision. At a median of 36 months (range 12-61) post-operatively, the median Quality of Life Questionnaire-C30 global health status score was 50 (range 33-83). CONCLUSION: Cystectomy is a last-resort management option for women with severely symptomatic end-stage bladders in the setting of antibiotic-recalcitrant rUTI. Patients should be counseled thoroughly regarding possible acute and long-term postoperative complications. Select patients, managed in high-volume referral centers, can benefit from robotic simple cystectomy with ileal conduit urinary diversion.

Introduction: To review the postrobotic-assisted sacrocolpopexy (RASC) course of women admitted for 23 hours post-RASC and identify events requiring intensive medical care or potentially leading to deleterious outcome or urgent readmission if that patient had same-day discharge (SDD) instead of observed overnight. Methods: Patients undergoing RASC from January to December 2020 at one institution were identified and relevant data were obtained via retrospective chart review. Patient exclusions: RASC start time after 12:00 PM, concurrent posterior colporrhaphy, rectopexy, or hysterectomy, or conversion to open. Results: Sixty-nine patients (median age 71 years old) met study criteria with majority American Society of Anesthesiologists class 2 (n = 46, 67%) or 3 (n = 22, 32%). Patient characteristics included prior abdominal surgeries (n = 58, 84%), prior hysterectomy/prolapse repair (n = 25, 37%), known allergy to pain medication (n = 25, 36%), and administration of a postoperative antiemetic (n = 37, 54%) or intra-/postoperative keterolac (n = 36, 52%). Median surgery length was 269 minutes. Postoperative events that may have resulted in urgent readmissions if they had SDD were observed in 6% of patients. In the 1st week post-RASC, there were no readmissions. Conclusions: In this limited quality assurance study, patients undergoing RASC experienced no major complications requiring intensive care. Postoperative events were almost entirely nausea and pain, with no readmissions within the 1st week.

Management of urinary tract infection (UTI) in postmenopausal women can be challenging. The recent rise in resistance to most of the available oral antibiotic options together with high recurrence rate in postmenopausal women has further complicated treatment of UTI. As such, intravesical instillations of antibiotics like gentamicin are being investigated as an alternative to oral antibiotic therapies. This study evaluates the efficacy of the candidate intravesical therapeutic VesiX, a solution containing the cationic detergent Cetylpyridinium chloride, against a broad range of uropathogenic bacterial species clinically isolated from postmenopausal women with recurrent UTI (rUTI). We also evaluate the cytotoxicity of VesiX against cultured bladder epithelial cells and find that low concentrations of 0.0063% and 0.0125% provide significant bactericidal effect toward diverse bacterial species including uropathogenic Escherichia coli (UPEC), Klebsiella pneumoniae, Enterococcus faecalis, Pseudomonas aeruginosa, and Proteus mirabilis while minimizing cytotoxic effects against cultured 5637 bladder epithelial cells. Lastly, to begin to evaluate the potential utility of using VesiX in combination therapy with existing intravesical therapies for rUTI, we investigate the combined effects of VesiX and the intravesical antibiotic gentamicin. We find that VesiX and gentamicin are not antagonistic and are able to reduce levels of intracellular UPEC in cultured bladder epithelial cells. IMPORTANCE: When urinary tract infections (UTIs), which affect over 50% of women, become resistant to available antibiotic therapies dangerous complications like kidney infection and lethal sepsis can occur. New therapeutic paradigms are needed to expand our arsenal against these difficult to manage infections. Our study investigates VesiX, a Cetylpyridinium chloride (CPC)-based therapeutic, as a candidate broad-spectrum antimicrobial agent for use in bladder instillation therapy for antibiotic-resistant UTI. CPC is a cationic surfactant that is FDA-approved for use in mouthwashes and is used as a food additive but has not been extensively evaluated as a UTI therapeutic. Our study is the first to investigate its rapid bactericidal kinetics against diverse uropathogenic bacterial species isolated from postmenopausal women with recurrent UTI and host cytotoxicity. We also report that together with the FDA-approved bladder-instillation agent gentamicin, VesiX was able to significantly reduce intracellular populations of uropathogenic bacteria in cultured bladder epithelial cells.

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.

ABSTRACT Objective To evaluate the subjective and objective outcomes of Macroplastique® (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: Naïve (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/configuration of MPQ. Success was defined 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 significantly improved over baseline in all groups. There was no significant 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 Macroplastique® improved subjective and objective outcome measures for SUI secondary to ISD as both a primary and secondary treatment option in women.

Purpose The treatment of urinary tract infections (UTI) with antibiotics is commonly used, but recurrence and antibiotic resistance have been growing and concerning clinicians. We studied whether the rapid onset of a protective biofilm may be responsible for the lack of effectiveness of antibiotics against selected bacteria. Materials and Methods Two established uropathogenic Escherichia coli strains, UTI89 and CFT073, and two Pseudomonas aeruginosa strains, PA01 and Boston-41501, were studied to establish a reliable biofilm formation process. Bacterial growth (BG) was determined by optical density at 600 nm (OD 600) using a spectrophotometer, while biofilm formation (BF) using crystal violet staining was measured at OD 550. Next, these bacterial strains were treated with clinically relevant antibiotics, ciprofloxacin HCl (200 ng/mL and 2 μg/mL), nitrofurantoin (20 μg/mL and 40 μg/mL) and ampicillin (50 μg/mL) at time points of 0 (T0) or after 6 hours of culture (T6). All measurements, including controls (bacteria -1% DMSO), were done in triplicates and repeated three times for consistency. Results The tested antibiotics effectively inhibited both BG and BF when administered at T0 for UPEC strains, but not when the antibiotic administration started 6 hours later. For Pseudomonas strains, only Ciprofloxacin was able to significantly inhibit bacterial growth at T0 but only at the higher concentration of 2 μg/mL for T6. Conclusion When established UPEC and Pseudomonas bacteria were allowed to culture for 6 hours before initialization of treatment, the therapeutic effect of selected antibiotics was greatly suppressed when compared to immediate treatment, probably as a result of the protective nature of the biofilm. .
