ABSTRACT

PURPOSE: Because multiple management options exist for clinical T1 renal masses, patients may experience a state of uncertainty about the course of action to pursue (ie, decisional conflict). To better support patients, we examined patient, clinical, and decision-making factors associated with decisional conflict among patients newly diagnosed with clinical T1 renal masses suspicious for kidney cancer. MATERIALS AND METHODS: From a prospective clinical trial, participants completed the Decisional Conflict Scale (DCS), scored 0 to 100 with < 25 associated with implementing decisions, at 2 time points during the initial decision-making period. The trial further characterized patient demographics, health status, tumor burden, and patient-centered communication, while a subcohort completed additional questionnaires on decision-making. Associations of patient, clinical, and decision-making factors with DCS scores were evaluated using generalized estimating equations to account for repeated measures per patient. RESULTS: Of 274 enrollees, 250 completed a DCS survey; 74% had masses ≤ 4 cm in size, while 11% had high-complexity tumors. Model-based estimated mean DCS score across both time points was 17.6 (95% CI 16.0-19.3), though 50% reported a DCS score ≥ 25 at least once. On multivariable analysis, DCS scores increased with age (+2.64, 95% CI 1.04-4.23), high- vs low-complexity tumors (+6.50, 95% CI 0.35-12.65), and cystic vs solid masses (+9.78, 95% CI 5.27-14.28). Among decision-making factors, DCS scores decreased with higher self-efficacy (-3.31, 95% CI -5.77 to -0.86]) and information-seeking behavior (-4.44, 95% CI -7.32 to -1.56). DCS scores decreased with higher patient-centered communication scores (-8.89, 95% CI -11.85 to -5.94). CONCLUSIONS: In addition to patient and clinical factors, decision-making factors and patient-centered communication relate with decisional conflict, highlighting potential avenues to better support patient decision-making for clinical T1 renal masses.

ABSTRACT

INTRODUCTION: Urology residency prepares trainees for independent practice. The optimal operative chief resident year experience to prepare for practice is undefined. We analyzed the temporal arc of cases residents complete during their residency compared to their chief year in a multi-institutional cohort. METHODS: Accreditation Council for Graduate Medical Education case logs of graduating residents from 2010 to 2022 from participating urology residency programs were aggregated. Resident data for 5 categorized index procedures were recorded: (1) general urology, (2) endourology, (3) reconstructive urology, (4) urologic oncology, and (5) pediatric urology. Interactions were tested between the trends for total case exposure in residency training relative to the chief resident year. RESULTS: From a sample of 479 resident graduates, a total of 1,287,433 total cases were logged, including 375,703 during the chief year (29%). Urologic oncology cases had the highest median percentage completed during chief year (56%) followed by reconstructive urology (27%), general urology (24%), endourology (17%), and pediatric urology (2%). Across the study period, all categories of cases had a downward trend in median percentage completed during chief year except for urologic oncology. However, only trends in general urology (slope of -0.68, P = .013) and endourology (slope of -1.71, P ≤ .001) were significant. CONCLUSIONS: Over 50% of cases completed by chief residents are urologic oncology procedures. Current declining trends indicate that residents are being exposed to proportionally fewer general urology and endourology cases during their chief year prior to entering independent practice.

ABSTRACT

While diversity and inclusion efforts have increased in urology, comparative analysis of personal statements from 2016-2017 and 2022-2023 residency applications showed few linguistic changes over time by gender or race/ethnicity. These results suggest the need for directed efforts to engage, mentor, and coach females and underrepresented minorities during medical school and the urology application process.

ABSTRACT

PURPOSE: Planning complex operations such as robotic-assisted radical prostatectomy requires surgeons to review 2-dimensional magnetic resonance imaging (MRI) cross-sectional images to understand 3-dimensional (3D), patient-specific anatomy. We sought to determine surgical outcomes for robotic-assisted radical prostatectomy when surgeons reviewed 3D, virtual reality (VR) models for operative planning. MATERIALS AND METHODS: A multicenter, randomized, single-blind clinical trial was conducted from January 2019 to December 2020. Patients undergoing robotic-assisted laparoscopic radical prostatectomy were prospectively enrolled and randomized to either a control group undergoing usual preoperative planning with prostate biopsy results and MRI only or to an intervention group where MRI and biopsy results were supplemented with a 3D VR model. The primary outcome measure was margin status, and secondary outcomes were oncologic control, sexual function and urinary function. RESULTS: Ninety-two patients were analyzed, with trends toward lower positive margin rates (33% vs 25%) in the intervention group, no significant difference in functional outcomes and no difference in traditional operative metrics (p >0.05). Detectable postoperative prostate specific antigen was significantly lower in the intervention group (31% vs 9%, p=0.036). In 32% of intervention cases, the surgeons modified their operative plan based on the model. When this subset was compared to the control group, there was a strong trend toward increased bilateral nerve sparing (78% vs 92%), and a significantly lower rate of postoperative detectable prostate specific antigen in the intervention subset (31% vs 0%, p=0.038). CONCLUSIONS: This randomized clinical trial demonstrated patients whose surgical planning involved 3D VR models have better oncologic outcomes while maintaining functional outcomes.

ABSTRACT

INTRODUCTION: Contemporary testis cancer management requires fastidious adherence to clinical guidelines and care principles, especially for those pursuing active surveillance (AS). However, real-world testis cancer care remains largely undescribed. Accordingly, we sought to assess the rigor of evaluation and monitoring among men with testis cancer. PATIENTS AND METHODS: Using North Carolina Central Cancer Registry data linked to insurance claims, we selected adult males diagnosed with primary testis cancer from 2003 to 2013. After identifying demographics, care setting, histology, stage, and index management, we evaluated the receipt of tumor markers, imaging, and clinic visits during initial evaluation and subsequent monitoring with respect to contemporaneous clinical guidelines. Care patterns were compared using chi-squared testing and multivariable logistic regression. RESULTS: Of 2526 men with primary testis cancer, we assembled a cohort of 487 with seminoma (59.3%) or nonseminoma (40.7%), losing most to a lack of insurance or continuous coverage. The cohort was predominantly white (92.4%) and had stage I disease (87.9%). Overall, 18.9% had complete tumor markers, staging imaging, and visits with 2 relevant specialists as recommended during their initial evaluation. For subsequent monitoring, 17.5% of patients with seminoma on active surveillance met minimal thresholds for recommended testing and follow-up during the first year vs. 21.9% and 34.9% of patients with seminoma treated with adjuvant radiation and chemotherapy, respectively. For nonseminoma, 10.1% of men on active surveillance met the minimal thresholds for recommended monitoring compared with 60.4% and 62.0% of those treated with surgery and chemotherapy, respectively. Recommended monitoring also differed by academic vs. community setting and receipt of recommended evaluation (P < .05). CONCLUSIONS: From real-world data, the evaluation and monitoring of patients with testis cancer appears substandard. Ongoing data and quality gaps highlight potential challenges with generating real-world evidence and ensuring adequate surveillance in this population.

ABSTRACT

Non-clear cell renal cell carcinoma (RCC) is a heterogeneous disease. We report a case of sarcomatoid non-clear cell RCC in a patient with underlying multiple sclerosis (MS) on immunosuppression with a complete pathologic response to pembrolizumab and axitinib. Comprehensive genomic profiling revealed pathogenic mutations in SETD2 and TP53 with high RNA expression levels of immune checkpoint proteins. Our case illustrates the importance of treatment selection based on presence of sarcomatoid features, underlying autoimmune disease, and genomic profiling.

ABSTRACT

OBJECTIVES: To assess a potential source of bias that could contribute to underrepresentation of minorities in urology, we analyzed differences in linguistic characteristics in personal statements between urology residency applicants of various racial and ethnic groups. METHODS: Personal statements submitted by urology residency applicants to a urology program were evaluated with Linguistic Inquiry and Word Count, a validated text analysis program. Analyzed statements and application characteristics were compared according to self-identified race/ethnicity of the applicant using multivariable analysis and independent sample T-tests. RESULTS: Of 342 submitted personal statements, 181 applicants self-identified as White non-Hispanic, 86 as Asian, and 75 as "underrepresented in medicine" (URM) including Black and Hispanic/Latino applicants. Asian and URM applicants listed more research projects (11.7 and 12.9 vs 8.8, P = .01) and URM applicants had slightly lower USMLE Step 1 scores (238.5 vs 244.6, P = .01) compared to White applicants. When evaluating personal statements, all applicants wrote with the same degree of analytical thinking. Asian applicants scored lower in authenticity (P = .03) and emotional tone (P = .04) while URM applicants scored higher in clout (P = .04) compared to White applicants. In use of pronouns, Asian applicants used 'we/us/our' more often (P < .01), URM applicants used 'you' more often (P = .02), and White applicants used 'I' more often (P = .01). CONCLUSION: Significant linguistic differences exist among urology personal statements by racial/ethnic groups that may perpetuate stereotypes and bias in the application process. Appreciating these differences may help applicants avoid possibly detrimental linguistics and help residency programs recruit and support urology applicants from underrepresented backgrounds.

ABSTRACT

OBJECTIVE: To gain insight into the perceptions of urology held by medical students as they enter the field, we analyzed the linguistic characteristics and gender differences in personal statements written by urology residency program applicants. METHODS: Personal statements were abstracted from residency applications to a urology residency program. Linguistic Inquiry and Word Count, a validated text analysis software, characterized the linguistic content of the statements. Analyzed statements were compared according to gender of the applicant using multivariate analysis, examining the association of applicant gender and statement characteristics. Multivariate analysis was also performed to determine the association of personal statement characteristics with matching into urology residency. RESULTS: Of 342 analyzed personal statements, no significant difference was found in statement characteristics between matched and unmatched applicants. Male and female applicants wrote with the same degree of overall analytical thinking, authenticity, and emotional tone. Clout, a measure of portrayed confidence, was low for both genders. Female applicants used more social and affective process words. Male applicants used more words indicating a sense of community and acceptance. Female applicants had more references to women within their statements. CONCLUSION: Significant linguistic differences exist among personal statements written by men and women applying to urology residency. Word usage differences follow societal gender norms. Statement content demonstrates a difference between genders in perceived sense of belonging, highlighting the importance of gender concordant mentorship within the field.

ABSTRACT

OBJECTIVE: To determine whether patient-reported health status, more so than comorbidity, influences treatment in men with localized prostate cancer. METHODS: Using Surveillance, Epidemiology, and End Results data linked with Medicare claims and CAHPS surveys, we identified men aged 65-84 diagnosed with localized prostate cancer from 2004 to 2013 and ascertained their National Cancer Institute (NCI) comorbidity score and patient-reported health status. Adjusting for demographics and cancer risk, we examined the relationship between these measures and treatment for the overall cohort, low-risk men aged 65-74, intermediate/high-risk men aged 65-74, and men aged 75-84. RESULTS: Among 2724 men, 43.0% rated their overall health as Excellent/Very Good, while 62.7% had a comorbidity score of 0. Beyond age and cancer risk, patient-reported health status was significantly associated with treatment. Compared to men reporting Excellent/Very Good health, men in Poor/Fair health less often received treatment (odds ratio [OR] 0.71, 95% confidence interval [CI] 0.56-0.90). Younger men with intermediate/high-risk cancer in Good (OR 0.60, 95% CI 0.41-0.88) or Fair/Poor (OR 0.49, 95% CI 0.30-0.79) health less often underwent prostatectomy vs radiation compared to men in Excellent/Very Good health. In contrast, men with NCI comorbidity score of 1 more often received treatment (OR 1.37, 95% CI 1.11-1.70) compared to men with NCI comorbidity score of 0. CONCLUSION: Patient-reported health status drives treatment for prostate cancer in an appropriate direction whereas comorbidity has an inconsistent relationship. Greater understanding of this interplay between subjective and empiric assessments may facilitate more shared decision-making in prostate cancer care.

ABSTRACT

OBJECTIVE: To implement Standard Opioid Prescribing Schedules (SOPS) based on opioid use following urologic surgeries and to evaluate how evidence-based prescribing schedules affect opioid use and patient reported outcomes. METHODS: Patients who underwent urologic surgeries within 6 procedure subtypes at UNC Health during the 2 study time periods ("pre-SOPS": 7/2017-1/2018, "post-SOPS": 7/2018-1/2019) were invited to complete a survey analyzing postoperative opioid usage, storage and disposal, and patient reported outcomes (including pain interference using a validated questionnaire). A pharmacy database provided medication prescribing data and patient demographics. During the pre-SOPS time period, baseline outcomes were measured. Following the pre-SOPS period, usage amounts were analyzed and Standard Opioid Prescribing Schedules were developed to guide prescriptions during the post-SOPS period. Descriptive summary statistics and appropriate t test or r2 were calculated. RESULTS: A total of 438 patients within 6 procedure types completed the survey (pre-SOPS: 282 patients, post-SOPS: 156 patients). Pre-SOPS, patients were prescribed significantly more 5-mg oxycodone tablets than used (20.9 vs 7.8, P <.001). Post-SOPS, compared to pre-SOPS amounts, patients were prescribed significantly fewer tablets (12.7 vs 20.9, P <.001) and used fewer tablets (5.3 vs 7.8, P = .003). No difference was observed in pain interference (average t-score (standard deviation): 54.33 (10.9) pre-SOPS vs 55.89 (9.1) post-SOPS, P = .125) or patient satisfaction (95% pre-SOPS vs 94% post-SOPS). CONCLUSION: Adherence to data-driven postoperative opioid prescribing schedules reduce opioid prescriptions and use without compromising pain interference or patient satisfaction. These results have important implications for urologists' ability to decrease opioid prescriptions and fight the opioid epidemic.

ABSTRACT

BACKGROUNDSurgery remains the frontline therapy for patients with localized clear cell renal cell carcinoma (ccRCC); however, 20%-40% recur. Angiogenesis inhibitors have improved survival in metastatic patients and may result in responses in the neoadjuvant setting. The impact of these agents on the tumor genetic heterogeneity or the immune milieu is largely unknown. This phase II study was designed to evaluate safety, response, and effect on tumor tissue of neoadjuvant pazopanib.METHODSccRCC patients with localized disease received pazopanib (800 mg daily; median 8 weeks), followed by nephrectomy. Five tumors were examined for mutations by whole exome sequencing from samples collected before therapy and at nephrectomy. These samples underwent RNA sequencing; 17 samples were available for posttreatment assessment.RESULTSTwenty-one patients were enrolled. The overall response rate was 8 of 21 (38%). No patients with progressive disease. At 1-year, response-free survival and overall survival was 83% and 89%, respectively. The most frequent grade 3 toxicity was hypertension (33%, 7 of 21). Sequencing revealed strong concordance between pre- and posttreatment samples within individual tumors, suggesting tumors harbor stable core profiles. However, a reduction in private mutations followed treatment, suggesting a selective process favoring enrichment of driver mutations.CONCLUSIONNeoadjuvant pazopanib is safe and active in ccRCC. Future genomic analyses may enable the segregation of driver and passenger mutations. Furthermore, tumor infiltrating immune cells persist during therapy, suggesting that pazopanib can be combined with immune checkpoint inhibitors without dampening the immune response.FUNDINGSupport was provided by Novartis and GlaxoSmithKline as part of an investigator-initiated study.

ABSTRACT

Over the past decade, despite the controversies surrounding prostate cancer screening, significant refinements have improved its application. PSA screening, although it has been questioned, appears to confer a mortality benefit and remains the most effective way to identify the possible presence of prostate cancer. Methods to improve the specificity of PSA screening and limit overdiagnosis of indolent cancers, including risk-stratified screening regimens, are currently being utilized. Certain imaging modalities, such as multiparametric MRI, have proven to be excellent adjuncts providing improved risk stratification and the ability for targeted biopsies; however, concerns over variability in interpretation and generalizability persist. A number of novel biomarkers have become available with nearly all demonstrating the ability to improve upon the specificity of PSA screening; however, optimal timing, direct comparisons, and usefulness in conjunction with imaging modalities remain to be elucidated. With the improvement in testing options and recognition of the risk/benefit ratio for men undergoing screening for prostate cancer, the increasing role of shared decision making in the process is emphasized.

ABSTRACT

INTRODUCTION: Computed tomography (CT) has limited diagnostic accuracy for staging of muscle-invasive bladder cancer (MIBC). [18F] Fluorodeoxyglucose positron emission tomography (FDG-PET)/magnetic resonance imaging (MRI) is a novel imaging modality incorporating functional imaging with improved soft tissue characterization. This pilot study evaluated the use of preoperative FDG-PET/MRI for staging of MIBC. PATIENTS AND METHODS: Twenty-one patients with MIBC with planned radical cystectomy were enrolled. Two teams of radiologists reviewed FDG-PET/MRI scans to determine: (1) presence of primary bladder tumor; and (2) lymph node involvement and distant metastases. FDG-PET/MRI was compared with cystectomy pathology and computed tomography (CT). RESULTS: Eighteen patients were included in the final analysis, most (72.2%) of whom received neoadjuvant chemotherapy. Final pathology revealed 10 (56%) patients with muscle invasion and only 3 (17%) patients with lymph node involvement. Clustered analysis of FDG-PET/MRI radiology team reads revealed a sensitivity of 0.80 and a specificity of 0.56 for detection of the primary tumor with a sensitivity of 0 and a specificity of 1.00 for detection of lymph node involvement when compared with cystectomy pathology. CT imaging demonstrated similar rates in evaluation of the primary tumor (sensitivity, 0.91; specificity, 0.43) and lymph node involvement (sensitivity, 0; specificity, 0.93) when compared with pathology. CONCLUSIONS: This pilot single-institution experience of FDG-PET/MRI for preoperative staging of MIBC performed similar to CT for the detection of the primary tumor; however, the determination of lymph node status was limited by few patients with true pathologic lymph node involvement. Further studies are needed to evaluate the potential role for FDG-PET/MRI in the staging of MIBC.

ABSTRACT

Importance: Planning complex operations such as robotic-assisted partial nephrectomy requires surgeons to review 2-dimensional computed tomography or magnetic resonance images to understand 3-dimensional (3-D), patient-specific anatomy. Objective: To determine surgical outcomes for robotic-assisted partial nephrectomy when surgeons reviewed 3-D virtual reality (VR) models during operative planning. Design, Setting, and Participants: A single-blind randomized clinical trial was performed. Ninety-two patients undergoing robotic-assisted partial nephrectomy performed by 1 of 11 surgeons at 6 large teaching hospitals were prospectively enrolled and randomized. Enrollment and data collection occurred from October 2017 through December 2018, and data analysis was performed from December 2018 through March 2019. Interventions: Patients were assigned to either a control group undergoing usual preoperative planning with computed tomography and/or magnetic resonance imaging only or an intervention group where imaging was supplemented with a 3-D VR model. This model was viewed on the surgeon's smartphone in regular 3-D format and in VR using a VR headset. Main Outcomes and Measures: The primary outcome measure was operative time. It was hypothesized that the operations performed using the 3-D VR models would have shorter operative time than those performed without the models. Secondary outcomes included clamp time, estimated blood loss, and length of hospital stay. Results: Ninety-two patients (58 men [63%]) with a mean (SD) age of 60.9 (11.6) years were analyzed. The analysis included 48 patients randomized to the control group and 44 randomized to the intervention group. When controlling for case complexity and other covariates, patients whose surgical planning involved 3-D VR models showed differences in operative time (odds ratio [OR], 1.00; 95% CI, 0.37-2.70; estimated OR, 2.47), estimated blood loss (OR, 1.98; 95% CI, 1.04-3.78; estimated OR, 4.56), clamp time (OR, 1.60; 95% CI, 0.79-3.23; estimated OR, 11.22), and length of hospital stay (OR, 2.86; 95% CI, 1.59-5.14; estimated OR, 5.43). Estimated ORs were calculated using the parameter estimates from the generalized estimating equation model. Referent group values for each covariate and the corresponding nephrometry score were summed across the covariates and nephrometry score, and the sum was exponentiated to obtain the OR. A mean of the estimated OR weighted by sample size for each nephrometry score strata was then calculated. Conclusions and Relevance: This large, randomized clinical trial demonstrated that patients whose surgical planning involved 3-D VR models had reduced operative time, estimated blood loss, clamp time, and length of hospital stay.

ABSTRACT

OBJECTIVE: To determine whether implicit gender bias exists in the urology residency application process, we compared linguistic differences in letters of recommendation (LOR) submitted for male and female applicants. METHODS: LOR were abstracted from residency applications to a urology residency program. Linguistic Inquiry and Word Count, a validated text analysis software program, characterized the linguistic content of the letters. Analyzed letters were compared according to gender of the applicant using multivariable analysis, examining the association of applicant gender, letter writer, and letter characteristics. Multivariable analysis was also performed to determine the association of letter characteristics with matching into a urology residency. RESULTS: Of 460 letters evaluated, letters for male applicants are written in a more authentic tone compared to letters written for female applicants. Letters written for male applicants contain significantly more references to personal drive, work, and power than letters written for female applicants. Significant differences are maintained on multivariable analysis when controlling for race and Step 1 score of the applicant. Letters with references to power were significantly more likely to be associated with an applicant who matched into urology than an applicant who didn't match. CONCLUSION: Significant linguistic differences exist among LOR written for men and women applying into urology, suggesting that gender bias may permeate resident recruitment. These differences may affect the likelihood of women matching into urology.

ABSTRACT

Human endogenous retroviruses (hERVs) are remnants of exogenous retroviruses that have integrated into the genome throughout evolution. We developed a computational workflow, hervQuant, which identified more than 3,000 transcriptionally active hERVs within The Cancer Genome Atlas (TCGA) pan-cancer RNA-Seq database. hERV expression was associated with clinical prognosis in several tumor types, most significantly clear cell renal cell carcinoma (ccRCC). We explored two mechanisms by which hERV expression may influence the tumor immune microenvironment in ccRCC: (i) RIG-I-like signaling and (ii) retroviral antigen activation of adaptive immunity. We demonstrated the ability of hERV signatures associated with these immune mechanisms to predict patient survival in ccRCC, independent of clinical staging and molecular subtyping. We identified potential tumor-specific hERV epitopes with evidence of translational activity through the use of a ccRCC ribosome profiling (Ribo-Seq) dataset, validated their ability to bind HLA in vitro, and identified the presence of MHC tetramer-positive T cells against predicted epitopes. hERV sequences identified through this screening approach were significantly more highly expressed in ccRCC tumors responsive to treatment with programmed death receptor 1 (PD-1) inhibition. hervQuant provides insights into the role of hERVs within the tumor immune microenvironment, as well as evidence that hERV expression could serve as a biomarker for patient prognosis and response to immunotherapy.

ABSTRACT

PURPOSE: Pressure on physicians to increase productivity is rising in parallel with administrative tasks, regulations, and the use of electronic health records (EHRs). Physician extenders and clinical pathways are already in use to increase productivity and reduce costs and burnout, but other strategies are required. We evaluated whether implementation of medical scribes in an academic urology clinic would affect productivity, revenue, and patient/provider satisfaction. METHODS: Six academic urologists were assigned scribes for 1 clinic day per week for 3 months. Likert-type patient and provider surveys were developed to evaluate satisfaction with and without scribes. Matched clinic days in the year prior were used to evaluate changes in productivity and physician/hospital charges and revenue. RESULTS: After using scribes for 3 months, providers reported increased efficiency (p value = 0.03) and work satisfaction (p value = 0.03), while seeing a mean 2.15 more patients per session (+ 0.96 return visits, + 0.99 new patients, and + 0.22 procedures), contributing to an additional 2.6 wRVUs, $542 in physician charges, and $861 in hospital charges per clinic session. At a gross collection rate of 36%, actual combined revenue was + $506/session, representing a 26% increase in overall revenue. At a cost of $77/session, the net financial impact was + $429 per clinic session, resulting in a return-to-investment ratio greater than 6:1, while having no effect on patient satisfaction scores. Additionally, with scribes, clinic encounters were closed a mean 8.9 days earlier. CONCLUSIONS: Implementing medical scribes in academic urology practices may be useful in increasing productivity, revenue, and provider satisfaction, while maintaining high patient satisfaction.

ABSTRACT

CONTEXT: Gender-specific functional and health-related quality of life (HRQOL) outcomes following radical cystectomy (RC) for bladder cancer (BCa) remain unclear, with many studies excluding women from the study population. OBJECTIVE: To better characterize female-specific functional outcomes following RC and urinary diversion for BCa. EVIDENCE ACQUISITION: We performed a critical review of PubMed/Medline and Embase in August 2015 according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement. Outcomes of interest included urinary function (for orthotopic neobladder), sexual function, bowel function, and quality of life. Excluded were nonbladder malignancies, RCs performed for neurogenic bladder dysfunction, and patients with exposure to radiation therapy prior to surgery. Forty-five publications were selected for inclusion in this analysis. EVIDENCE SYNTHESIS: Included reports addressed urinary function (34 studies), sexual function (11 studies), and HRQOL (9 studies). All studies had a high risk of bias and ranged significantly in sample size, inclusion criteria, and follow-up time, precluding meaningful meta-analysis. Daytime incontinence approximated 20%, nighttime incontinence 20%, and hypercontinence 10-20%. Sexual function appeared to be better among those patients undergoing genitalia-sparing RC, but generally poor outcomes were noted among those undergoing routine RC. Only 40% of studies assessed sexual function using standardized instruments. HRQOL differences between diversion types appeared to be minimal, whereas comparisons with the general population revealed significant differences in emotional problems, role functioning, fatigue, and appetite. CONCLUSIONS: Functional outcomes among women undergoing RC for BCa are poorly studied with limitations regarding use of validated questionnaires, heterogeneous patient populations, and small sample sizes. Collaborative efforts will be needed to better define functional outcomes among this poorly studied patient population. PATIENT SUMMARY: We reviewed functional outcomes following cystectomy among women with bladder cancer. We found that urinary, sexual, and bowel function and quality of life are poorly studied among women, with function ranging significantly across studies.
