Monoclonal Gammopathy of Renal Significance (MGRS) - Case Series from a Tertiary Center in Kerala.

Monoclonal gammopathy of renal significance (MGRS) has gained importance because identifying the monoclonal deposit and addressing it, rather than treating renal dysfunction as the primary pathology, has salvaged the patients from progressing into end-stage renal disease. Since it affects elderly population, there could be a propensity to misdiagnose them with cardiorenal syndrome. We present four patients of MGRS diagnosed from our center. They presented with proteinuria or unexplained renal dysfunction. Three of the patients were diagnosed to have amyloidosis, of which two had lambda-type and one had kappa amyloidosis. The fourth patient had fibrillary glomerulonephritis with kappa restriction, further evaluation of which led to diagnosis of chronic lymphocytic leukemia. Absence of "M" band in protein electrophoresis and a normal bone marrow study should not stop physicians from further evaluation. Quantitative serum immunofixation electrophoresis and electron microscopic examination of renal biopsy have become a comprehensive diagnostic tool in such patients.

Percutaneous tibial neuromodulation initial therapy compliance and subsequent third-line treatment patterns.

PURPOSE: Percutaneous Tibial Neuromodulation (PTNM) is used to treat Overactive Bladder (OAB). This analysis summarizes patient adherence to PTNM treatment and examines trends of other third-line therapy use during and after PTNM. METHODS: Optum's deidentified Clinformatics® Data Mart Database (CDM) and CMS Research Identifiable Files were queried for adults with OAB symptoms and who underwent PTNM treatment (2019-2020). We evaluated the proportion of patients who completed 12 visits within 1 year, and defined patients as treatment compliant if 12 PTNM visits were completed within 12 weeks. We then identified the proportion of patients who used other third-line therapies after PTNM and stratified these patients based on their PTNM therapy compliance status. RESULTS: 2302 patients met selection criteria from CDM and 16,473 patients from CMS. The proportion of patients completing a full PTNM treatment course increased over time; from 16% at week 12% to 42% by week 52 (CDM) and 24% to 38% (CMS). Other third-line therapy use increased over time and was higher for PTNM noncompliant versus compliant patients at 52 weeks: onabotulinumtoxinA was 6.5% versus 5.7% for noncompliant versus compliant (CMS, p = 0.0661) and 6.4% versus 4.9% (CDM, p = 0.035), SNM trial procedure was 6.5% versus 2.5% (CDM, p = 0.002) and 4.2% versus 2.0% (CMS, p = 0.010). CONCLUSIONS: Most patients are noncompliant with recommended PTNM treatment regimen. Albeit low, third-line therapy was pursued more frequently by noncompliant patients. Given low compliance, the effectiveness of PTNM may be compromised. Alternative implantable technologies may be needed to assure effectiveness of neuromodulation.

Maternity Leave Satisfaction Among Physicians Compared with Nonphysician Professionals.

Objective: The objective of this study was to compare maternity leave satisfaction between physicians and nonphysicians. Currently, paid maternal leave is not guaranteed in the United States, resulting in palpable dissatisfaction among parents. Previous studies have shown associations between length of paid leave and career satisfaction and maternal happiness. Materials and Methods: A Qualtrics® electronic survey was distributed to female professionals through email and social media from April 2019 to March 2020. Inclusion criterion was ≥1 child by birth or adoption, or active pregnancy. Continuous and categorical data were analyzed using two-sample t-test and chi-square, respectively. Results: Of 808 respondents, 77% were physicians. Mean age at birth/adoption of first child was higher in physicians versus nonphysicians (32.1 years vs. 29.7 years; p < 0.001). Physicians took shorter maternity leave than nonphysicians (10.9 weeks vs. 12.0 weeks, p = 0.017) with half of that time paid by employers (5.4 weeks vs. 5.9 weeks, p = 0.2). Dissatisfaction was high among physicians (85.1%) and nonphysicians (92.4%) that correlates with maternity leave compensation dissatisfaction (49% vs. 71.3%, p < 0.001). Thirty-four percent of physicians versus 41% of nonphysicians stated that their health was negatively impacted by maternity leave length. Physicians and nonphysicians reported similar incidences of depression, and breastfeeding, delivery, and other postpartum complications. When queried, 38.8% of physicians and 57% of nonphysicians said they would desire >16 weeks of paid maternity leave (p < 0.001). Conclusions: In conclusion, dissatisfaction among professional women on maternity leave duration and compensation is high in the United States. Given health implications for both mother and child, this should invite further discussion and changes.

Antibiotic use, best practice statement adherence, and UTI rate for intradetrusor onabotulinumtoxin-A injection for overactive bladder: A multi-institutional collaboration from the SUFU Research Network (SURN).

INTRODUCTION: Onabotulinumtoxin A (BTX-A) is a well-established treatment for overactive bladder (OAB). The American Urological Association (AUA) 2008 Antibiotic Best Practice Statement (BPS) recommended trimethoprim-sulfamethoxazole or fluoroquinolone for cystoscopy with manipulation. The aim of the study was to evaluate concordance with antibiotic best practices at the time of BTX-A injection and urinary tract infection (UTI) rates based on antibiotic regimen. METHODS: Men and women undergoing first-time BTX-A injection for idiopathic OAB with 100 units in 2016, within the SUFU Research Network (SURN) multi-institutional retrospective database were included. Patients on suppressive antibiotics were excluded. The primary outcome was concordance of periprocedural antibiotic use with the AUA 2008 BPS antimicrobials of choice for "cystoscopy with manipulation." As a secondary outcome we compared the incidence of UTI among women within 30 days after BTX-A administration. Each outcome was further stratified by procedure setting (office vs. operating room; OR). RESULTS: Of the cohort of 216 subjects (175 women, 41 men) undergoing BTX-A, 24 different periprocedural antibiotic regimens were utilized, and 98 (45%) underwent BTX-A injections in the OR setting while 118 (55%) underwent BTX-A injection in the office. Antibiotics were given to 86% of patients in the OR versus 77% in office, and 8.3% of subjects received BPS concordant antibiotics in the OR versus 82% in office. UTI rates did not vary significantly among the 141 subjects who received antibiotics and had 30-day follow-up (8% BPS-concordant vs. 16% BPS-discordant, CI -2.4% to 19%, p = 0.13). A sensitivity analysis of UTI rates based on procedure setting (office vs. OR) did not demonstrate any difference in UTI rates (p = 0.14). CONCLUSIONS: This retrospective multi-institutional study demonstrates that antibiotic regimens and adherence to the 2008 AUA BPS were highly variable among providers with lower rates of BPS concordant antibiotic use in the OR setting. UTI rates at 30 days following BTX-A did not vary significantly based on concordance with the BPS or procedure setting.

Fibrin microthrombi in bladder urothelium after SARS-CoV-2 infection: Case report.

A 45-year-old male with diabetes, hypertension and hyperlipidemia was referred to urology due to persistent symptoms of urinary frequency, urgency, nocturia, erectile dysfunction, and constant pain localized to the bladder, pelvis, and perineal area, 3-4 months after SARS-CoV-2 infection. A bladder biopsy showed urothelial mucosa and submucosa with hemorrhage and fibrin microthrombi in blood vessels. Hydrodistention of the bladder and pelvic floor physical therapy resolved symptoms, though bladder and pain symptoms returned upon reinfection with SARS-CoV-2. Urinalysis revealed elevated urinary interleukin-8, which may indicate localized bladder inflammation.

Incidence of New or Worsening Overactive Bladder Among Patients with a Prior SARS-CoV-2 Infection: A Cohort Study.

Background: Literature is sparse on COVID-19-associated cystitis (CAC), a novel condition comprising frequency, urgency, and nocturia after COVID-19 infection. Objective: To determine the incidence of CAC and correlation with SARS-CoV-2 antibody levels. Design setting and participants: This was a retrospective study in which urinary symptoms were scored using the International Consultation on Incontinence Questionnaire-overactive bladder (ICIQ-OAB) at three time points: before the pandemic (January 2020), 2 mo after COVID-19 infection (if applicable), and at the time of the study (May 2021). The setting was a regional health care system. The 18 785 healthcare employees who took part in the BLAST COVID study group were invited to participate, of whom 1895 responded. Outcome measurements and statistical analysis: The outcome measured was the percentage of COVID-positive patients with a significant change on ICIQ-OAB over time. Pearson's χ2 test was used for comparison of categorical data, and one-way analysis of variance for continuous data and multivariate analysis. A sample size of 618 was calculated for power of 80% and α = 0.05. Results and limitations: Of the 1895 participants, 31.9% (n = 605) were positive for COVID-19 according to positive serology or a polymerase chain reaction (PCR) test. Of these, 492 were PCR-positive and had 2-mo postinfection data, with 36.4% (179/492) reporting an increase of ≥1 point on the ICIQ-OAB compared to baseline (before the pandemic), with de novo OAB in 22% of these cases (40/179). Comparison of symptoms between baseline and the study time revealed that 27.4% (31/113) of those with positive serology only (asymptomatic COVID) and 37.8% (186/492) of those with PCR positivity (symptomatic COVID) had an increase of ≥1 point on the ICIQ-OAB, compared to 15.8% (n = 204) of uninfected patients, with odds ratios of 2.013 (95% confidence interval [CI] 1.294-3.138; p = 0.0015) and 3.236 (95% CI 2.548-4.080; p < 0.0001), respectively. The retrospective nature of the study and the volunteer sample are limitations. Conclusions: COVID-19 infection increases the risk of developing new or worsening OAB symptoms. Patient summary: We compared overactive bladder symptoms in a large group of participants between individuals with and without a previous COVID-19 infection. We found that symptomatic infection was associated with a three times greater risk of developing new or worsening overactive bladder symptoms among COVID-19 patients.

Incomplete bladder emptying and urinary tract infections after botulinum toxin injection for overactive bladder: Multi-institutional collaboration from the SUFU research network.

INTRODUCTION: Onabotulinumtoxin A (BTX-A) is an effective therapy for overactive bladder (OAB), however, adverse events may prevent patients from initiating therapy. The study objective was to report real-world rates of incomplete emptying and urinary tract infection (UTI) in men and women undergoing BTX-A for OAB. METHODS: Eleven clinical sites performed a retrospective study of adults undergoing first-time BTX-A injection (100 units) for idiopathic OAB in 2016. Exclusions included: postvoid residual (PVR) > 150 ml, prior BTX-A, pelvic radiation, or need for preprocedure catheterization. Primary outcomes at 6 months were incomplete emptying (clean intermittent catheterization [CIC] or PVR ≥ 300 ml without the need for CIC); and UTI (symptoms with either positive culture or urinalysis or empiric treatment). We compared rates of incomplete emptying and UTI within and between sexes, using univariate and multivariable models. RESULTS: 278 patients (48 men and 230 women) met inclusion criteria. Mean age was 65.5 years (range: 24-95). 35% of men and 17% of women had incomplete emptying. Men had 2.4 (95% CI: 1.04-5.49) higher odds of incomplete emptying than women. 17% of men and 23.5% of women had ≥1 UTI, the majority of which occurred within the first month following injection. The strongest predictor of UTI was a history of prior UTI (OR: 4.2 [95% CI: 1.7-10.3]). CONCLUSIONS: In this multicenter retrospective study, rates of incomplete emptying and UTI were higher than many previously published studies. Men were at particular risk for incomplete emptying. Prior UTI was the primary risk factor for postprocedure UTI.

Exceeding the maximum recommended dose of onabotulinumtoxinA in urologic patients.

INTRODUCTION: Although onabotulinumtoxinA (BTX) is commonly utilized by multiple specialists, it is unclear how often or reasons why patients receive more than the recommended maximum dose. The goal of this study was to determine if excess BTX use occurs in urologic practice. MATERIALS AND METHODS: This retrospective cohort identified patients who underwent intravesical BTX between 01/2013-12/2017 at an academic hospital. All BTX administrations for any indication were identified. Excess BTX was defined as receiving greater than the current recommended maximum dosage of 400 units within 3 months. RESULTS: A total of 361 patient received intravesical BTX. These patients underwent 755 procedures using BTX, 673(89.1%) intravesical and 82(10.9%) non-urologic. Other site injections occurred in 14 patients, and 7 (50.0%) of these patients had at least one instance of excess. In these 7 patients, there were a total of 15 instances of excess use from either a single injection (3 instances) or a subsequent injection within 3 months (12 instances). No excess use occurred in patients who received only intravesical BTX. Discordance was noted between the administered dose, pharmacy dispensing information (46.9%), and nursing medication administration record (MAR) (54.3%). All dosages matched in only 39.2% procedures. CONCLUSIONS: Although excess BTX use is overall infrequent in urologic practice, it is common in our patients prescribed the drug by non-urologic providers (50%). Pharmacy dispensing and nursing MAR information are unreliable in determining the actual administered dose. This highlights the need for providers to further discuss BTX use with patients and the need for improved tracking of BTX administration and communication across specialties.

Changes in patient reported outcome measures after treatment for female urethral stricture.

INTRODUCTION: There is a paucity of patient reported outcome measure (PROM) data for women with urethral strictures. To address this gap, we aim to evaluate change in PROM among women who underwent surgery for a stricture. METHODS: American Urological Association Symptom Index (AUA-SI) and Urogenital Distress Inventory (UDI-6) data from a multi-institutional retrospective cohort study of women treated for urethral stricture was assessed. RESULTS: Fifty-seven women had either AUA-SS or UDI-6 and 26 had baseline and postoperative data for either. Most women underwent urethroplasty (77%) and the majority (73%) remained stricture free at median follow-up of 21 months (interquartile range [IQR] 7-37). The median baseline AUA-SI was 21 (IQR 12-28) and follow-up was 10 (IQR 5-24). After treatment, there was a median decrease of 12 (IQR -18 to -2) in AUA-SI (p = 0.003). The median AUA Quality of life (QOL) score at baseline and follow-up were 6 (IQR 4-6) and 3 (IQR 2-5), respectively. There was a median AUA-QOL improvement of 2 points (-5,0; p = 0.007) from a baseline 5 (unhappy) to 3 (mixed). Median UDI-6 scores were 50 (IQR 33-75) at baseline and 17 (IQR 0-39), at follow-up. After treatment, there was a median decrease of 19 (-31 to -11; p = 0.01). CONCLUSION: Women with urethral strictures have severe lower urinary tract symptoms which improved after surgery. This study substantiates the claims that recognizing and treating women with urethral stricture disease greatly improves lower urinary tract symptoms and QOL.

Treatment of urethral stricture disease in women: A multi-institutional collaborative project from the SUFU research network.

AIM: Female urethral stricture disease is rare and has several surgical approaches including endoscopic dilations (ENDO), urethroplasty with local vaginal tissue flap (ULT) or urethroplasty with free graft (UFG). This study aims to describe the contemporary management of female urethral stricture disease and to evaluate the outcomes of these three surgical approaches. METHODS: This is a multi-institutional, retrospective cohort study evaluating operative treatment for female urethral stricture. Surgeries were grouped into three categories: ENDO, ULT, and UFG. Time from surgery to stricture recurrence by surgery type was analyzed using a Kaplan-Meier time to event analysis. To adjust for confounders, a Cox proportional hazard model was fit for time to stricture recurrence. RESULTS: Two-hundred and ten patients met the inclusion criteria across 23 sites. Overall, 64% (n = 115/180) of women remained recurrence free at median follow-up of 14.6 months (IQR, 3-37). In unadjusted analysis, recurrence-free rates differed between surgery categories with 68% ENDO, 77% UFG and 83% ULT patients being recurrence free at 12 months. In the Cox model, recurrence rates also differed between surgery categories; women undergoing ULT and UFG having had 66% and 49% less risk of recurrence, respectively, compared to those undergoing ENDO. When comparing ULT to UFG directly, there was no significant difference of recurrence. CONCLUSION: This retrospective multi-institutional study of female urethral stricture demonstrates that patients undergoing endoscopic management have a higher risk of recurrence compared to those undergoing either urethroplasty with local flap or free graft.

Refractory bladder dysfunction: A multi-institutional experience with intravesical botulinum toxin-a injection in adult patients who underwent previous augmentation cystoplasty.

OBJECTIVE: Augmentation cystoplasty is a treatment option for neurogenic lower urinary tract dysfunction as well as severe, refractory, complicated idiopathic overactive bladder. In some patients, symptoms may persist or recur postoperatively, and there is little guidance on management in this setting. In this study, we reviewed the use of intravesical onabotulinum toxin type A (BTX-A) in patients who had undergone augmentation cystoplasty. MATERIAL AND METHODS: Retrospective chart review was performed at two institutions, identifying patients who underwent augmentation cystoplasty and were subsequently treated with intravesical BTX-A. Demographics, and preoperative and postoperative findings were collected. RESULTS: In total, 21 (16 female, 5 male) patients (mean age: 37.2 years) with previous augmentation cystoplasty were identified. In 17 patients with urodynamic data, mean maximum cystometric capacity was 312 mL, and decreased compliance and detrusor overactivity were noted in 53% and 48% patients, respectively. Combined intradetrusor/intra-augment injections were performed in 11 patients, and the remaining 10 patients received detrusor-only injections. A total of 18 patients (86%) reported subjective improvement with no significant difference associated with site of injection (p=0.59). A total of 17 patients (77%) underwent repeat injections; on average, patients underwent 3.3 injections with interval of 8.8 months between injections. CONCLUSION: BTX-A injection was shown to subjectively improve storage symptoms and continence after augmentation cystoplasty in the majority of patients. In this cohort, patients had good subjective response regardless of site of injection, and most patients benefited from repeat injections. Prospective studies are needed to better evaluate the efficacy and ideal sites of BTX-A injection in the setting of refractory voiding dysfunction following augmentation cystoplasty.

Structural and functional characterization of Solanum lycopersicum phosphatidylinositol 3-kinase C2 domain.

Phosphatidylinositol 3-kinases (PI3Ks) are characterized by the presence of a C2 domain at the N-terminal end (class I, III); or at both the N-terminal and C-terminal ends (class II), sometimes including a Plextrin homology domain and/or a Ras domain. Plant PI3Ks are analogous to the class III mammalian PI3K. An N-terminal fragment (~170 aa) of the tomato PI3K regulatory domain including the C2 domain, was cloned and expressed in a bacterial system. This protein was purified to homogeneity and its physicochemical properties analyzed. The purified protein showed strong binding with monophosphorylated phosphatidylinositols, and the binding was dependent on calcium ion concentration and pH. In the overall tertiary structure of PI3K, C2 domain showed unique characteristics, having three antiparallel beta-sheets, hydrophobic regions, acidic as well as alkaline motifs, that can enable its membrane binding upon activation. To elucidate the functional significance of C2 domain, transgenic tobacco plants expressing the C2 domain of PI3K were generated. Transgenic plants showed defective pollen development and disrupted seed set. Flowers from the PI3K-C2 transgenic plants showed delayed wilting, and a decrease in ethylene production. It is likely that introduction of the PI3K-C2 segment may have interfered with the normal binding of PI3K to the membrane, delaying the onset of membrane lipid catabolism that lead to senescence.

Adherence to AUA Clinical Guidelines: Motivations and Barriers.

INTRODUCTION: The AUA (American Urological Association) has been producing clinical practice guidelines to inform its members on standards of care since 1994. While adherence to these clinical practice guidelines varies, there are limited data on ways to improve adherence or reduce barriers to use. METHODS: A survey was developed to query adherence to AUA clinical practice guidelines and identify barriers to use. Five specific clinical practice guidelines were queried from various areas of urological care. Reasons for lack of adherence or perceived barriers to clinical practice guideline implementation were elicited. The survey was sent to a random sample of AUA members in clinical practice in the United States. RESULTS: Of the 2,455 AUA members surveyed 260 (10.6%) responded, with 148 (6.0%) answering all questions concerning AUA guidelines. Overall adherence to AUA guidelines was 72.7%. The guideline with the most adherence was for microhematuria (90.68%) and the least followed guideline was on the timing of post-vasectomy semen analysis (53.33%). The mean self-reported rate of adherence to the 5 guidelines was 81.7% (range 71.3% to 95.03%). The top reason given for lack of adherence was not agreeing with the guideline. The most commonly reported barriers to following clinical practice guidelines included insurance coverage (29.08%) and disagreement with guidelines (21.92%). CONCLUSIONS: Overall there is an optimistic view of the quality and applicability of clinical practice guidelines. These survey data help identify areas for improvement. We recommend e-mail distribution of clinical practice guidelines, improvement in ease of use for the mobile app, incorporation of clinical practice guidelines into the electronic medical record, and addition of CliffsNotes® and flowchart format to future clinical practice guidelines.

Upregulation of Phosphatidylinositol 3-Kinase (PI3K) Enhances Ethylene Biosynthesis and Accelerates Flower Senescence in Transgenic Nicotiana tabacum L.

Phosphatidylinositol 3-kinase (PI3K) is a key enzyme that phosphorylates phosphatidylinositol at 3'-hydroxyl position of the inositol head group initiating the generation of several phosphorylated phosphatidylinositols, collectively referred to as phosphoinositides. The function of PI3K in plant senescence and ethylene signal transduction process was studied by expression of Solanum lycopersicum PI3K in transgenic Nicotiana tabacum, and delineating its effect on flower senescence. Detached flowers of transgenic tobacco plants with overexpressed Sl-PI3K (OX) displayed accelerated senescence and reduced longevity, when compared to the flowers of wild type plants. Flowers from PI3K-overexpressing plants showed enhanced ethylene production and upregulated expression of 1-aminocyclopropane-1-carboxylic acid oxidase 1 (ACO1). Real time polymerase chain reaction (PCR) analysis showed that PI3K was expressed at a higher level in OX flowers than in the control. Seedlings of OX-lines also demonstrated a triple response phenotype with characteristic exaggerated apical hook, shorter hypocotyls and increased sensitivity to 1-aminocyclopropane-1-carboxylate than the control wild type seedlings. In floral tissue from OX-lines, Solanum lycopersicum phosphatidylinositol 3-kinase green fluorescent protein (PI3K-GFP) chimera protein was localized primarily in stomata, potentially in cytoplasm and membrane adjacent to stomatal pores in the guard cells. Immunoblot analysis of PI3K expression in OX lines demonstrated increased protein level compared to the control. Results of the present study suggest that PI3K plays a crucial role in senescence by enhancing ethylene biosynthesis and signaling.

Outcomes of three sling procedures at the time of abdominal sacral colpopexy.

INTRODUCTION: A sling at time of sacral colpopexy (SCP) for apical pelvic organ prolapse (POP) is valuable in the treatment of overt, urodynamic, and occult stress urinary incontinence (SUI). As there is no current agreement regarding the optimal choice of sling in these women, we compare the outcomes of three sling procedures in this population: autologous rectus fascia bladder neck sling (ARF), retropubic midurethral sling (RPM), and transobturator midurethral sling (TOM). METHODS: We performed a retrospective single institution, single-surgeon review of data identifying women with minimum follow-up of 12 months who underwent a concomitant sling and SCP following urodynamics with and without POP reduction. Preoperative and postoperative evaluation included objective and subjective assessment. Cure required absence of subjective and objective SUI. RESULTS: Out of 187 women, 152 (81%) met inclusion criteria (49 ARF, 58 RPM, and 45 TOM). There were no significant differences among sling groups regarding demographics. SUI cure rates were not significantly different between sling groups, or within each group after stratification by overt and occult SUI. QoL indices improved significantly after surgery for the entire cohort. CONCLUSIONS: All three sling types appear to produce similar cure rates of SUI when done concomitantly with SCP. There did not appear to be any significant differences when stratified by occult or overt SUI. No sling type was associated with more postoperative complications. Larger studies are necessary to confirm the findings of this single-institution, retrospective study. Neurourol. Urodynam. 36:482-485, 2017. © 2016 Wiley Periodicals, Inc.

Inferior Vena Cava Filter Erosion Causing Symptomatic Obstructive Hydronephrosis.

BACKGROUND: Transcaval inferior vena cava (IVC) filter penetration involving the urinary tract is rare, but has been previously reported. We herein present unique management of symptomatic hydronephrosis secondary to erosion of an IVC filter limb into the lumen of the proximal right ureter. CASE PRESENTATION: A 59-year-old woman presented with abdominal and right flank pain in October 2015 and was found to have right hydronephrosis, apparently secondary to obstruction from erosion of an IVC filter limb into the proximal right ureter. This was effectively managed with percutaneous, endovascular, and endourologic procedures, without the need for a major invasive surgical procedure. CONCLUSION: Endovascular removal of the IVC filter was performed safely in this case and can be considered when the urinary tract is involved in filter erosion.

Female bladder outlet obstruction: an update on diagnosis and management.

PURPOSE OF REVIEW: The diagnosis and evaluation of bladder outlet obstruction (BOO) in women remains a challenging topic. The goal of this study is to review recent literature and summarize the diagnosis and management of BOO with special focus on recent progress. RECENT FINDINGS: In recent years, numerous advances in the area of female BOO have taken place including a movement towards unified diagnostic criteria, summary of functional and anatomic causes, and exploration of potential diagnostic options. SUMMARY: This review discusses the known diagnosis and management of female bladder outlet obstruction, yet highlights specific functional causes, new criteria available for diagnosis, and long-term results of treatment options.

Change in urinary storage symptoms following treatment for female stress urinary incontinence.

INTRODUCTION AND HYPOTHESIS: Sling surgery is common for stress urinary incontinence (SUI). Yet many women have stress-predominant mixed urinary incontinence (MUI). The change in urgency/urge urinary incontinence (U/UUI) following treatment is not well documented. Our aim was to assess changes in U/UUI in women undergoing a sling placement for MUI and correlate this with improvement in quality of life (QOL). METHODS: This was a retrospective review of women treated for SUI with either an autologous rectus fascia pubovaginal sling (AF-PVS) or synthetic retropubic midurethral sling (MUS). Validated questionnaires-Urogenital Distress Inventory (UDI-6), Incontinence Impact Questionnaire-Short Form (IIQ-7), and visual analog scale (VAS) were obtained pre- and postoperatively. The independent association between change in storage symptoms and subjective cure-as defined by improved overall score on UDI-6, VAS score ≥ 7, or both -were assessed using multivariate logistic regression. RESULTS: Nine hundred and twenty-seven women were identified for inclusion; 718 (77.5 %) had preoperative MUI, of whom 487 (67.8 %) received an MUS and 231 (32.2 %) an AF-PVS. Similar objective cure rates were noted following MUS vs. AF-PVS (78.2 % vs. 71.9 %, p = 0.315). Subjectively, women treated with MUS experienced greater improvement in U/UUI (72.8 % vs. 57.6 %, p = <0.001) than AF-PVS. Multivariate analysis showed MUS patients were more than twice as likely to show subjective improvement in UDI-6 and VAS scores than the AF-PVS cohort. Postoperatively, validated questionnaires were significantly associated with storage symptom outcome. CONCLUSIONS: Patients with U/UUI experience significant symptom improvement following treatment for MUI. QoL assessment following surgery is directly correlated with improvement in U/UUI.
