RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Vaginal mesh exposures and infections are recognized complications of open and laparoscopic sacrocolpopexy performed for vault prolapse. In severe cases, complete sacrocolpopexy mesh removal may be necessary. This case report presents a 72-year-old woman with previous mesh sacrocolpopexy who presented with infected mesh and recurrent vaginal bleeding despite multiple attempts at surgical transvaginal mesh excision. A life-threatening massive hemorrhage occurred intra-operatively. After several failed attempts to control bleeding, hemorrhage Occluder™ Pins were successfully placed by vascular surgery to control presacral veins. Although an exceedingly rare complication, anticipation and rapid management of life-threatening bleeding are critical to save life during complicated mesh removals.

RESUMEN

PURPOSE: Antibiotic-refractory recurrent urinary tract infections are challenging to manage. Prior studies have shown that, in selected patients, electrofulguration of cystitis may disrupt potential nidus of recurrent urinary tract infections. We report on long-term outcomes of electrofulguration in women with at least 5 years of follow-up. MATERIALS AND METHODS: Following Institutional Review Board approval, we analyzed a cohort of nonneurogenic women with ≥3 symptomatic recurrent urinary tract infections/y and inflammatory lesions on cystoscopy who underwent electrofulguration, excluding those with alternate identifiable etiology for recurrent urinary tract infections or less than 5-year follow-up. Preoperative characteristics, antibiotic regimens, and annual urinary tract infections were reported. Primary outcome was clinical cure (0-1 urinary tract infection/y), improvement (>1 and <3/y) or failure (≥3/y) at last follow-up. Secondary outcomes included need for antibiotics or repeat electrofulguration. A subanalysis was performed for women with >10-year follow-up. RESULTS: From 2006 to 2012, 96 women met study criteria with median age 64. Median follow-up was 11 years (IQR: 10-13.5); 71 women had >10-year follow-up. Prior to electrofulguration, 74% used daily antibiotic suppression, 5% used postcoital prophylaxis, 14% used self-start therapy, and 7% were not on prophylaxis. At last post-electrofulguration visit, 72% of women were cured, 22% improved, and 6% failed. Antibiotic usage decreased post-electrofulguration (P < .05). Five percent were on continuous antibiotics at last follow-up as compared to 74% on continuous antibiotics pre-electrofulguration (McNemar P < .05). Nineteen percent of women underwent a repeat electrofulguration. CONCLUSIONS: In menopausal women with over 5-year follow-up after electrofulguration for antibiotic-refractory recurrent urinary tract infections, there appears to be durable clinical cure and improvement, with decreased need for long-term antibiotics.

RESUMEN

OBJECTIVE: To describe the technique of vaginoscopy with Holmium:YAG and Thulium laser treatment of upper vaginal mesh exposure after mesh sacrocolpopexy (MSC) as well as evaluate treatment efficacy. METHODS: Following IRB approval, a chart review of all patients who underwent laser treatment of upper vaginal mesh exposure during vaginoscopy at a single institution between 2013 and 2022 was performed. Demographic information, previous mesh placement history, presenting symptoms, physical examination and vaginoscopy findings, imaging, laser type and settings, operating time, complications, and follow-up including examination and office vaginoscopy findings were extracted from electronic medical records. RESULTS: Five patients and 6 surgical encounters were identified. All patients had a history of MSC and symptomatic mesh exposure at the vaginal apex, which was tented up and difficult to access by traditional transvaginal mesh excision. Five patients underwent vaginal mesh treatment with laser with no further vaginal mesh exposure on follow-up exam or vaginoscopy. One patient was found to have a small recurrence at 4 months and underwent a second treatment with negative findings on vaginoscopy 7.9 months post-operatively. There were no complications. CONCLUSION: Vaginoscopy using a rigid cystoscope and laser treatment of upper vaginal mesh exposure using a Holmium:YAG or Thulium laser is a safe and quick method which led to definitive symptom resolution.

RESUMEN

INTRODUCTION AND HYPOTHESIS: To evaluate how women with uncomplicated antibiotic-recalcitrant recurrent urinary tract infections (RUTIs) and extensive inflammatory bladder lesions on office cystoscopy responded to electro-fulguration (EF) to eliminate these chronic bladder sites. METHODS: After IRB approval, a retrospective study of non-neurogenic women with RUTIs, inflammatory lesions on cystoscopy, and who underwent EF was performed. Lesions were classified through a simplified staging system based on the extent of bladder wall involvement. Only those with extensive bladder wall involvement (stages 3 and 4) at the time of EF were analyzed in this report. Six months after EF, an office cystoscopy was performed, with endoscopic success defined as no lesions seen. The primary clinical outcome was number of symptomatic UTIs after EF, defined as cure (0/year), improvement (1-2/year), and failure (≥3/year). RESULTS: From 2007 to 2019, a total of 57 women met the study criteria, 30 stage 3 and 27 stage 4. Nineteen (63%) were endoscopically successful in stage 3 and 11 (41%) in stage 4. Mean follow-up was 2.9 years (stage 3) and 3.1 years (stage 4). All had at least a 6-month UTI follow-up after the 6 months of office cystoscopy, with 15 patients cured, 37 improved, and 5 failed (all stage 4). CONCLUSIONS: Although EF only resulted in 63% complete endoscopic resolution, the majority experienced a decrease in the frequency of UTIs, suggesting that EF can be durably effective even in women with very extensive cystitis lesions.

RESUMEN

Postmenopausal women are severely affected by recurrent urinary tract infection (rUTI). The urogenital microbiome is a key component of the urinary environment. However, changes in the urogenital microbiome underlying rUTI susceptibility are unknown. Here, we perform shotgun metagenomics and advanced culture on urine from a controlled cohort of postmenopausal women to identify urogenital microbiome compositional and function changes linked to rUTI susceptibility. We identify candidate taxonomic biomarkers of rUTI susceptibility in postmenopausal women and an enrichment of lactobacilli in postmenopausal women taking estrogen hormone therapy. We find robust correlations between Bifidobacterium and Lactobacillus and urinary estrogens in women without urinary tract infection (UTI) history. Functional analyses reveal distinct metabolic and antimicrobial resistance gene (ARG) signatures associated with rUTI. Importantly, we find that ARGs are enriched in the urogenital microbiomes of women with rUTI history independent of current UTI status. Our data suggest that rUTI and estrogen shape the urogenital microbiome in postmenopausal women.

RESUMEN

Klebsiella spp. commonly cause both uncomplicated urinary tract infection (UTI) and recurrent UTI (rUTI). Klebsiella quasipneumoniae, a relatively newly defined species of Klebsiella, has been shown to be metabolically distinct from Klebsiella pneumoniae, but its type 1 and type 3 fimbriae have not been studied. K. pneumoniae uses both type 1 and type 3 fimbriae to attach to host epithelial cells. The type 1 fimbrial operon is well conserved between Escherichia coli and K. pneumoniae apart from fimK, which is unique to Klebsiella spp. FimK contains an N-terminal DNA binding domain and a C-terminal phosphodiesterase (PDE) domain that has been hypothesized to cross-regulate type 3 fimbriae expression via modulation of cellular levels of cyclic di-GMP. Here, we find that a conserved premature stop codon in K. quasipneumoniae fimK results in truncation of the C-terminal PDE domain and that K quasipneumoniae strain KqPF9 cultured bladder epithelial cell association and invasion are dependent on type 3 but not type 1 fimbriae. Further, we show that basal expression of both type 1 and type 3 fimbrial operons as well as cultured bladder epithelial cell association is elevated in KqPF9 relative to uropathogenic K. pneumoniae TOP52. Finally, we show that complementation of KqPF9ΔfimK with the TOP52 fimK allele reduced type 3 fimbrial expression and cultured bladder epithelial cell attachment. Taken together these data suggest that the C-terminal PDE of FimK can modulate type 3 fimbrial expression in K. pneumoniae and its absence in K. quasipneumoniae may lead to a loss of type 3 fimbrial cross-regulation. IMPORTANCE K. quasipneumoniae is often indicated as the cause of opportunistic infections, including urinary tract infection, which affects >50% of women worldwide. However, the virulence factors of K. quasipneumoniae remain uninvestigated. Prior to this work, K. quasipneumoniae and K. pneumoniae had only been distinguished phenotypically by metabolic differences. This work contributes to the understanding of K. quasipneumoniae by evaluating the contribution of type 1 and type 3 fimbriae, which are critical colonization factors encoded by all Klebsiella spp., to K. quasipneumoniae bladder epithelial cell attachment in vitro. We observe clear differences in bladder epithelial cell attachment and regulation of type 3 fimbriae between uropathogenic K. pneumoniae and K. quasipneumoniae that coincide with a structural difference in the fimbrial regulatory gene fimK.

RESUMEN

OBJECTIVES: To evaluate office flexible cystoscopy findings in the evaluation and management of postmenopausal women with recurrent urinary tract infections (RUTIs). METHODS: An IRB-approved, prospectively maintained database of women evaluated for RUTIs at a tertiary care center was retrospectively reviewed by an independent investigator for flexible cystoscopy (FC) findings and related treatment decisions over three consecutive years. Data reviewed in the electronic medical record (EMR) included demographics, UTI history, history of diabetes, hormone replacement therapy (HRT), prior urological surgeries, sexual activity, coital antibiotic prophylaxis use, urine culture findings, antibiotic resistance/allergies, cystoscopy, and treatment plan. RESULTS: Between 2017 and 2019, 113 consecutive postmenopausal women, mostly Caucasian, underwent flexible office cystoscopy to complete their RUTI evaluation. Eighty-four women (74%) had abnormal cystoscopy findings. The rate of overall abnormal findings on cystoscopy increased yearly, including findings of trigonitis (p = 0.022). Other abnormal cystoscopy findings, as well as post-evaluation treatment plans, did not significantly differ over time. Trigonitis was the most common (67%) finding on cystoscopy. RUTI management included exposed urethral/bladder mesh removal and/or electrofulguration of chronic cystitis areas. CONCLUSIONS: Flexible cystoscopy, as an office diagnostic procedure, can provide valuable information of underlying etiology of RUTIs and allow directed management.

RESUMEN

PURPOSE: To study human bladder biopsies to investigate urothelial response to UTI, expression of uroplakin, and urothelial response after healing from cystoscopy with electrofulguration (CEF) treatment for antibiotic-recalcitrant RUTI. METHODS: Following IRB approval, cold cup bladder biopsies from "no cystitis" and "cystitis" regions were obtained from women with antibiotic-recalcitrant rUTI undergoing CEF under anesthesia. "No cystitis" and "cystitis" biopsies from 14 patients (5 had prior CEF, 9 naïve) were analyzed by immunofluorescence (IF) confocal microscopy using antibodies against uroplakin-IIIa. For an additional 6 patients (2 prior CEF, 4 naïve), only "cystitis" area biopsies were taken and analyzed. Cytokeratin 5 (marker for squamous metaplasia) staining was performed on 14 patients. RESULTS: In healthy tissue, uroplakin-IIIa staining was observed as a contiguous line on the luminal surface of umbrella cells. In "cystitis" areas for 19/20 patients, there was either no uroplakin-IIIa staining observed or spotty (+) staining. The "cystitis" regions of all patients had less intense uroplakin-IIIa staining compared to the matched "no cystitis" area in the same patient. In patients post-CEF but requiring repeat EF for persistent RUTI lesions, healed areas served as control and in 3 of 7 patients no uroplakin-IIIa staining was observed. Squamous metaplasia was observed in 10 patients. CONCLUSION: In bladders of postmenopausal women with antibiotic-recalcitrant RUTI, areas with visible cystitis expressed less uroplakin-IIIa, supporting the model of urothelial exfoliation in response to UTI.

RESUMEN

Objective: Tamoxifen complicates management of conditions such as urinary tract infections (UTIs), urinary incontinence (UI), and/or pelvic organ prolapse (POP) that traditionally benefit from hormonal intake; thus, we reviewed our experience in managing these hormonally deprived women. Materials and Methods: After IRB approval, electronic medical records from women with current use or history of tamoxifen use and referred to a tertiary care center with female pelvic medicine and reconstructive surgery expertise for UTI, UI, and/or POP were reviewed. Results: From 2015 to 2020, 32 women treated with tamoxifen 10-40 mg for a median of 4 years were referred for UTIs (9), UI (10), symptomatic POP (8), or for a combination of these (5). Participants with UTI treated with antibiotics, prophylactic supplements, and/or electrofulguration had satisfactory response at median follow-up of 1 year (interquartile range [IQR]: 0.5-1). Ten of 15 women with UI chose intervention, with no self-reported UI recurrence at median follow-up of 2.5 years (IQR: 1-3). All but one participant with POP underwent vaginal or open/robotic mesh repairs, with satisfactory outcomes at median follow-up of 3 years (IQR: 2-7). Conclusions: The management of UTIs, UI, and POP in women on tamoxifen or unable to benefit from hormonal intake is challenging, but traditional interventions can be considered with satisfactory results.

RESUMEN

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.

RESUMEN

INTRODUCTION: The detection of vaginal mesh/suture exposure can be challenging due to pain and varied location. We reviewed our experience with office-based vaginoscopy to evaluate these women. METHODS: An IRB-approved review of an electronic medical record database at a tertiary care center provided the list of all vaginoscopy procedures performed by a single FPMRS (Female Pelvic Medicine and Reconstructive Surgery) specialist. Vaginoscopy was performed with a flexible cystoscope and findings photographically documented. Demographics, indications, findings, additional imaging (translabial ultrasound and magnetic resonance imaging), and intraoperative findings for corroboration were collected by a neutral investigator. RESULTS: From 2014 to 2020, 159 vaginoscopies were conducted in 128 women with 23 having repeat procedures. Presenting symptoms prompting vaginoscopy included dyspareunia (46), hispareunia (6), vaginal bleeding or discharge (24), or pelvic pain (31), with multiple symptoms present in 63%. The yield of vaginoscopy in detecting mesh/suture exposure was 32% (51/159): 33% (23/71) without prior removal attempts and only vaginal complaints, 37% (18/49) with history of prior surgical mesh/suture removal, 38% (10/26) with history of prior office mesh removal at another facility and none (0/13) when evaluating for bladder mesh complications. Comparatively, only 3 exposures were suspected on imaging. The apex was the most common site of exposure (63%). Mesh/suture removal was mostly performed via a vaginal approach (90%), with 93% corroboration with office-based findings. CONCLUSIONS: Office-based vaginoscopy is a safe and simple tool to exclude or detect mesh or suture exposure in selected patients and precisely locate the site/size of exposure to aid in surgical planning of mesh/suture-related complications.

RESUMEN

INTRODUCTION AND HYPOTHESIS: The objective was to report on the very long-term outcome of a published series of autologous pubovaginal slings (PVS) in women with stress urinary incontinence (SUI). METHODS: Following institutional review board approval, a cohort of well characterized, non-neurogenic women who underwent an autologous PVS (primary [PVS1] and secondary [PVS2]) for SUI was re-evaluated for their very long-term outcome status. Data collected included demographics, validated questionnaires (Urogenital Distress Inventory - short form [UDI-6], Incontinence Impact Questionnaire - short form 7, quality of life), SUI retreatment/operations, and subjective patient-reported SUI improvement (%) and symptom recurrence. The primary outcome was success defined as UDI-6 question 3 (SUI) ≤ 1 and no SUI retreatment/operation. Patients not seen in clinic for 2 years were contacted via a standardized phone interview. RESULTS: From 83 patients with 7-year intermediate follow-up data, 34 (PVS1 = 18, PVS2 = 16) had very long-term follow-up based on clinic visit (7) or phone interviews (27). Those lost to follow-up (49), including 5 deceased, did not differ in demographics and intermediate outcomes from the followed cohort, but lived further away (>75 miles). At a mean age of 74 years, and with a median follow-up of 14.5 years, 53% met the success criteria (PVS1 = 44%, PVS2 = 63%). Mean postoperative questionnaire scores did not differ significantly between intermediate and very long-term follow-ups, and long-term outcomes between PVS1 and PVS2 remained similar. CONCLUSIONS: A majority of women with long-term follow-up after PVS for primary and secondary SUI remained successful more than 14 years after their surgery. Both groups, PVS1 and PVS2, fared equally well, confirming the durability of PVS as a treatment alternative for SUI.
