Takeuchi M, Tamada T, Higaki A, Kojima Y, Ueno Y, Yamamoto A. Pictorial review of the diagnosis of muscle-invasive bladder cancer using vesical imaging-reporting and data system (VI-RADS). Abdom Radiol (NY) 2024:10.1007/s00261-024-04424-3. [PMID: 38900320 DOI: 10.1007/s00261-024-04424-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2024] [Revised: 05/25/2024] [Accepted: 05/27/2024] [Indexed: 06/21/2024]
Abstract
The Vesical Imaging-Reporting and Data System (VI-RADS) is a standard magnetic resonance imaging (MRI) and diagnostic method for muscle-invasive bladder cancer that was published in 2018. Several studies have demonstrated that VI-RADS has high diagnostic power and reproducibility. However, reading VI-RADS requires a certain amount of expertise, and radiologists need to be aware of the various pitfalls. MRI of the bladder includes T2-weighted imaging (T2WI), diffusion-weighted imaging (DWI), and dynamic contrast-enhanced imaging (DCEI). T2WI is excellent for understanding anatomy. DWI and DCEI show high contrast between the tumor and normal anatomical structures and are suitable for staging local tumors. Bladder tumors are classified into five categories according to their size and morphology and their positional relationship to the bladder wall based on the VI-RADS diagnostic criteria. If the T2WI, DWI, and DCEI categories are the same, the category is the VI-RADS category. If the categories do not match, the DWI category is the VI-RADS category. If image quality of DWI is not evaluable, the DCEI category is the final category. In many cases, DWI is dominant, but this does not mean that T2WI and DCEI can be omitted from the reading of the bladder. In this educational review, typical and atypical teaching cases are demonstrated, and how to resolve misdiagnosis and the limitations of VI-RADS are discussed. The most important aspect of VI-RADS reading is to practice multiparametric reading with a solid understanding of the characteristics and role of each sequence and an awareness of the various pitfalls.

Abstract
Intradiverticular transitional cell carcinoma (TCC) of the bladder poses unique challenges due to its presentation within the bladder diverticula. This review synthesizes current knowledge on the diagnosis and management of this condition, emphasizing the need for early detection to optimize patient outcomes. The literature underscores the importance of tailored treatment strategies, ranging from radical surgeries to adjuvant chemotherapy, to combat the aggressive nature of intradiverticular TCC. Additionally, stringent post-treatment surveillance protocols are vital in addressing high recurrence rates. Future research directions include biomarker identification, comparative efficacy studies of treatment modalities, and the exploration of innovative therapeutic approaches such as immunotherapy. Longitudinal studies analyzing patient outcomes will provide valuable insights into survival rates and quality of life post-treatment, informing future clinical guidelines. This comprehensive review aims to enhance understanding and management strategies for intradiverticular TCC, paving the way for improved patient care and outcomes in this challenging form of bladder cancer.

Sensitivity of urine cytology in detecting high-grade urothelial carcinoma in patients with neoplastic urinary bladder diverticula: A major cancer center experience. Cancer Cytopathol 2024; 132:144-151. [PMID: 38054371 DOI: 10.1002/cncy.22782] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 09/28/2023] [Accepted: 10/18/2023] [Indexed: 12/07/2023]
Abstract
BACKGROUND Bladder diverticula are herniations of bladder urothelium and mucosa through the muscularis propria. The reported incidence of neoplasia arising in bladder diverticula is widely variable. The authors' objective was to study the characteristics and sensitivity of urine cytology in these patients with emphasis on primary intradiverticular bladder cancer (IDBC). METHODS A 17-year, retrospective review of all resected bladder diverticula associated with bladder carcinoma was performed. Cases that had complete diverticular resections and preresection urine samples were included in this study. The cases were divided into either primary IDBC or primary extradiverticular bladder cancer (EDBC). Demographic data and urine cytology characteristics were recorded, and sensitivity was calculated. For IDBC, a comparison between voided and cystoscopic urines was done for cases that had both collection methods performed. RESULTS Of 70 patients with IDBC, 47 patients had urine cytology results that were either positive for high grade-urothelial carcinoma (HG-UC) or suspicious for HG-UC. The sensitivity for HG-UC in IDBC samples was 80%, compared with 82% in EDBC samples (p > .05). Also, 28 patients in the IDBC group had both voided and cystoscopic urine samples for comparisons; in seven patients, the voided urine sample yielded a more definitive diagnosis; in 10 patients, the cystoscopic urine sample yielded a more definitive diagnosis; and, in 11 patients, both samples were equally diagnostic (p > .05). CONCLUSIONS The characteristics and sensitivity of urine cytology in bladder diverticula were investigated in association with neoplasia, with an emphasis on primary intradiverticular bladder cancer. The results indicated that urine cytology remains a reliable screening and diagnostic test for detecting IDBC, with sensitivity similar to that for detecting EDBC, and no significant difference was noted between voided and cystoscopic samples.

Abstract
BACKGROUND In Sweden, all patients with urinary bladder cancer (UBC) are recorded in the Swedish National Register for Urinary Bladder Cancer (SNRUBC). The purpose of this study was to validate the registered clinical tumour categories (cT-categories) in the SNRUBC for Norrland University Hospital, Sweden, from 2009 to 2020, inclusive. METHODS The medical records of all 295 patients who underwent radical cystectomy for the treatment of UBC were reviewed retrospectively. Possible factors impacting the cT-categories were identified. To optimise cT-classification, computed tomography urography of all patients with suspected tumour-associated hydronephrosis (TAH) or suspected tumour in bladder diverticulum (TIBD) were retrospectively reviewed by a radiologist. Discrepancy was tested with a logistic regression model. RESULTS cT-categories differed in 87 cases (29.5%). Adjusted logistic regression analysis found TIBD and TAH as significant predictors for incorrect registration; OR = 7.71 (p < 0.001), and OR = 17.7, (p < 0.001), respectively. In total, 48 patients (68.6%) with TAH and 12 patients (52.2%) with TIBD showed discrepancy regarding the cT-category. Incorrect registration was mostly observed during the years 2009-2012. CONCLUSION The study revealed substantial incorrect registration of cT-categories in SNRUBC. A major part of the misclassifications was related to TAH and TIBD. Registration of these variables in the SNRUBC might be considered to improve correct cT-classification.

Abstract
PURPOSE Bladder diverticula (BD) are usually asymptomatic, but may increase the risk of infections, stones, or malignancy, likely due to urinary stasis within the BD. We aim to characterize the risk of bladder cancer (BC) within diverticula. METHODS Retrospective review was conducted of patients diagnosed with BD between 1994 and 2021 at a single institution. Cancer risk was characterized using descriptive statistics and multivariable logistic regression as appropriate. RESULTS We identified 764 patients with mean age 68 years, the majority of whom were male (87%) and Caucasian (86%). Of this total, 13.3% (102/764) had a diagnosis of BC and 35.3% of this subset (36/102) had definitive cancer within the BD. Diverticulectomy or partial cystectomy was performed in 13.6% (104/764), 76% of whom were preoperatively presumed to have benign disease. Surgical patients were younger and had larger BD. Of the 79 patients who underwent diverticulectomy without preoperative suspicion for cancer, 5 were incidentally diagnosed with BC on final pathology. On multivariable logistic regression, male gender [odds ratio (OR) = 2.6, p = 0.03] and increasing age (OR = 1.02, p = 0.03) were independent risk factors for BC diagnosis. Indwelling catheter, recurrent urinary tract infections (UTIs), and bladder stones did not affect the risk of BC. CONCLUSIONS The majority of patients with BD are not managed with surgery. BC is identified in a small but considerable proportion of patients with BD, with an even lower rate of incidentally diagnosed cancer among those undergoing BD surgery. Male gender and increasing age increased the risk of BC diagnosis.

Abstract
INTRODUCTION There are various treatment options for symptomatic bladder diverticulum, including robotic-assisted laparoscopic bladder diverticulectomy, open and endoscopic techniques. But, to date, the optimal surgical technique remains unclear. OBJECTIVE To present the preliminary long-term follow-up results of a novel technique of dextranomer/hyaluronic acid copolymer (Deflux) plus autologous blood injection for correction of hutch diverticulum in patients with concomitant vesicoureteral reflux (VUR). PATIENT AND METHOD We retrospectively reviewed four patients who had hutch diverticulum with concomitant VUR and had undergone submucosal Deflux following autologous blood injection. Patients with neurogenic bladder, posterior urethral valve, or voiding dysfunction were excluded from the study. Success was defined as the resolution of the diverticulum, hydronephrosis, and hydroureter on ultrasonography at a 3-month follow-up and long-term symptom-free period. RESULTS Four patients with hutch diverticula were included. The median age at the time of surgery was 6.1 (range 3-8) years. Three of them had unilateral VUR, and one had bilateral VUR. During the procedure, a mean of 0.625 ml Deflux plus a mean of 1.25 ml autologous blood were injected submucosally for correction of VUR. Additionally, a mean of 1.62 ml Deflux plus a mean of 1.75 ml autologous blood were injected submucosally to occlude the diverticulum. The median follow-up was 4.6 (range 4-8) years. This method had excellent success in all patients in the current study with no postoperative complications such as febrile urinary tract infection, or diverticulum, hydroureter, or hydronephrosis in follow-up ultrasounds. CONCLUSIONS Submucosal injection of Deflux plus autologous blood injection can be a successful endoscopic intervention for treatments of hutch diverticulum in patients with concomitant VUR. Deflux injection can be a simple and cost-effective technique.

Abstract
Bladder diverticula are defined as an outpouching of the mucosa into the muscle layer of the bladder wall. There is a well-known link between urinary bladder diverticula and tumors arising within the diverticula. They are rare with an incidence rate of 0.8%-10%. We report an intradiverticular urothelial carcinoma in a 72-year-old man with a known history of multiple episodes of acute urinary retention and urinary tract infections, followed by transurethral resection of the benign prostatic hyperplasia.

Abstract
OBJECTIVE Intradiverticular bladder tumors (IDBT) are uncommon clinical entities. We reviewed the literature for clinical presentation, diagnosis and therapeutic options to establish recommendations for diagnostic and therapeutic management. METHODS Bibliographic research was performed using PubMed from database inception until October 15, 2022. A pooled analysis was performed of 498 patients with IDBT presented in the literature. The evaluation included patient sex, age, diagnostic methods, symptoms, localization of the tumor, tumor staging, tumor histopathology, treatment, and the presence of recurrence. To express results, descriptive statistics were used appropriately. RESULTS The mean age at diagnosis was 64.81 years (range 49 days to 84 years). The ratio between men and women was ≈ 24:1, suggesting a male predominance (85% male, 3.6% female). The most common presenting symptom was gross hematuria (60.88%). Most of the patients had cystoscopy (56.85%) and intravenous or computed tomography urography (52.01%). Regarding tumor staging, most of the patients were diagnosed with pT1 tumors. For the histopathology of IDBT, 87.95% of the specimens were transitional cell carcinomas and in 10.84% there were concomitant CIS. Regarding the treatment, radical cystectomy was chosen in 34.34%, partial cystectomy in 26.66%, diverticulectomy in 15.95% and transurethral resection of bladder tumour (TURBT) in 16.36% of the patients. CONCLUSIONS Most common diagnostic tool for IDBT seems to be cystoscopy followed by computerized tomography urogram. Due to the absence of muscle layer in the diverticulum and the highgrade histology of most of them at diagnosis, cystectomy is the first therapeutic choice. However, for patients that are not considered appropriate candidates or for those presenting with lowgrade and low volume tumors, TURBT is a good option.

Abstract
Background: Observational studies have suggested a possible association between benign prostate hyperplasia (BPH) and bladder cancer (BLCA). However, these studies are prone to errors and limitations or confounding factors, making them unsuitable for assessing the causal relationship between BPH and BLCA. Objective: Two-sample Mendelian randomization (MR) was performed to determine a possible association between genetically predicted BPH and the risk of BLCA. Methods: A two-sample MR analysis was performed utilizing the Integrative Epidemiology Unit genome-wide association (GWAS) database of the Medical Research Council, United Kingdom A series of control steps, including five primary methods, were performed to identify the most suitable instrumental variables (IVs) for MR analysis. Sensitivity analysis was conducted to avoid statistical errors, including heterogeneity and pleiotropic bias. Results: Genetic variants associated with BPH (P < 5 × 10-8) and BLCA (P < 5 × 10-6) were identified as instrumental variables and assessed using GWAS summary data (BPH, 4,670 cases vs. 458,340 controls; BLCA, 1,279 cases vs. 372,016 controls). BPH exhibited a positive effect on the occurrence of BLCA (inverse variance weighted (IVW), odds ratio (OR) = 1.095, 95% confidence interval (CI) = 1.030-1.165, p = 0.003), but there was no causal effect for BLCA on BPH (IVW, OR = 1.092, 95% CI = 0.814-1.465, p = 0.554). Conclusion: Genetically predicted BPH was associated with a higher risk of BLCA in all histological subtypes. In contrast, the evidence was not significant to back the causality of genetically induced BLCA on BPH. These findings indicate that BPH plays a key role in developing BLCA in the European population. Further studies are needed to uncover the underlying mechanisms.

Abstract
Introduction and importance Neoplasms arising from vesical diverticula are rare clinical entities known as intradiverticular bladder tumors. The bladder diverticulum harboring these tumors can be congenital or acquired. Congenital diverticula are predominantly found in children and are extremely rare in adults. Case presentation A 56-year-old male admitted to our hospital with a 10-days history of painless gross hematuria and blood clots. Physical examination and vital signs were unremarkable. Radiologic examination revealed a bladder diverticulum with a mass inside it. Pathological examination confirmed the diagnosis of TCC tumor arising from congenital bladder diverticula. Clinical discussion While intradiverticular bladder tumors account for only 1% of all bladder tumors، and the finding of a congenital bladder diverticulum is a rare anomaly in adults, the concurrence of a tumor arising within a congenital bladder diverticulum is almost non-existent in adults. Conclusion We aimed to present a rare case of urothelial carcinoma arising from a congenital diverticulum in an adult while highlighting the diagnostic and therapeutic options used in managing such tumors. Congenital diverticula are predominantly found in children and are extremely rare in adults. The concurrence of a tumor arising within a congenital bladder diverticulum is almost non-existent in adults. Physicians should always consider the possibility of tumors developing within these diverticula.

Abstract
AIMS Since October 2018, urinary bladder diverticulum resections at our Department of Urology have been carried out with robot assistance and with minimal invasivion, Paediatrical urological and robot-assisted minimally invasive urological surgery for the Bamberg Social Foundation were performed with the DaVinci robotic systemTM. The aim of the present study was to record the surgical results of our patients and to compare these if necessary with available data on optimal diagnostic and therapy. METHODS In this retrospective analysis, we included all patients who received RAHDR between October 2018 and March 2020. The primary endpoints were postoperative blood loss (postoperative haemoglobin decrease), the operation time (min), complications according to the Clavien-Dindo classification, length of hospital stay (days), postoperative residual urine, postoperative urine extravasation at the anastomosis of the bladder, postoperative quality of life and postoperative satisfaction with micturition. RESULTS We reviewed a total of 11 patients, all of whom were male. Mean age was 64.8 years (52-82). Average BMI was 26.5 (19-37). 3 patients were ranked with ASA score III, 5 with II and 3 with I. The average residual urine value preoperatively was 183 ml (90-240). A cystogram to rule out extravasation was performed on day 6 postoperatively. The mean duration of surgery was 212 min (148-294) and the mean duration of hospitalisation was 7.6 days (6-10). The mean residual urinary value after surgery was 25 ml (10-60). The mean postoperative maximum of flow was measured at 27.7 ml/s (11-55). No contrast agent extravasation in the cystogram was detected in any of the patients. The complications according to Clavien were not measurable. The mean postoperative haemoglobin decrease was 1.61 g/dl (0-3. 2). CONCLUSIONS In most cases, the removal of one or more bladder diverticula is possible using the minimally invasive robotic technique. Various surgeries such as YV-bladder neck plastic, prostate adenoma enucleation, bladder stone restoration, and inguinal herniotomy can be carried out simultaneously. A robot-assisted urinary bladder diverticulum resection is an effective and gentle procedure. However, it must be considered that it brings financial disadvantages due to the lack of adequate representation within the German DRG-system (Diagnosis Related Groups).

Prognostic Utility of MRI Features in Intradiverticular Bladder Tumor. Acad Radiol 2022; 29:219-228. [PMID: 33162319 PMCID: PMC8096867 DOI: 10.1016/j.acra.2020.10.010] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2020] [Revised: 10/01/2020] [Accepted: 10/05/2020] [Indexed: 02/03/2023]
Abstract
BACKGROUND Intradiverticular bladder tumors (IDBT) are rare but clinically important, as they are difficult to assess endoscopically due to limited anatomic access and risk of perforation. MRI may be helpful in assessing IDBT and providing relevant staging and prognostic information. PURPOSE To assess MRI findings of IDBT and their relationship with overall survival. METHODS This retrospective study included 31 consecutive patients with IDBT undergoing MRI from 2008 to 2018 identified through electronic medical records and PACS database search. Two radiologists independently assessed the following MRI features: size (>3 vs ≤3 cm), diverticular neck involvement, Vesical Imaging-Reporting and Data System (VI-RADS) score (>3 vs ≤3), perivesical fat infiltration, additional tumors and suspicious pelvic lymph nodes. Overall survival was estimated using Kaplan-Meier analysis; and the relationship with clinicopathological and MRI features was determined using the Cox proportional-hazards regression model. Inter-reader agreement was assessed using intraclass correlation coefficients (ICC) and Cohen's kappa (K). RESULTS Median follow-up was 1044 days (interquartile range, 474-1952 days). Twenty-six (83.9%) patients underwent surgical treatment with or without neoadjuvant chemotherapy. On MRI, greater tumor size (>3 cm), diverticular neck involvement, perivesical extension, and suspicious lymph nodes were associated with lower overall survival (HR = 3.6-8.1 and 4.3-6.3 for the 2 radiologists, p ≤ 0.03). Other clinicopathological or MRI findings were not associated with survival (p = 0.27-0.65). Inter-reader agreement was excellent for tumor size (ICC = 0.991; 95% CI 0.982-0.996), fair for VI-RADS (K = 0.52, 95% CI, 0.22-0.82), and moderate for others (K = 0.61-0.79). CONCLUSION In patients with IDBT, several MRI features were significantly associated with overall survival. Utilizing all available clinicopathological and imaging information may improve estimation of prognosis.

Abstract
Aim Optimal management of bladder cancer requires an accurate, standardised and timely pathological diagnosis, and close communication between surgeons and pathologists. Here, we provide an update on pathology reporting standards of transurethral resections of the bladder and cystectomies. Methods We reviewed recent literature, focusing on developments between 2013 and 2021. Results Published reporting standards developed by pathology organizations have improved diagnosis and treatment. Tumor sub-staging and subtyping has gained increased attention. Lymph nodes continue to be an area of debate, and their staging has seen minor modifications. Several tasks, particularly regarding specimen preparation (“grossing”), are not yet standardized and offer opportunity for improvement. Molecular classification is rapidly evolving, but currently has only limited impact on management. Conclusion Pathological reporting of bladder cancer is continuously evolving and remains challenging in some areas. This review provides an overview of recent major developments, with a particular focus on published reporting standards.

Abstract
Transurethral resection of bladder tumor (TURBT) is still the gold standard for the diagnosis, treatment, and staging of nonmuscle invasive bladder cancer. En bloc resection of bladder tumor (EBRT) has been recently introduced to overcome the limitations of conventional TURBT. EBRT potential advantages are (1) complete resection, (2) a more precise and controlled resection (potentially fewer complications), (3) better sample orientation for histopathology analysis, (4) presence of detrusor in the specimen, and (5) less tumor seeding on normal urothelium by tumor fragments. This article aimed to present a step-by-step technique of conventional TURBT and EBRT with thulium laser support. We also aimed to provide tips and tricks for a correct surgical procedure and postoperative patient care. Finally, clinical outcomes of TURBT versus EBRT were reviewed.

Abstract
Objective: We present a one-session procedure for treating bladder diverticula combined with benign prostatic hyperplasia (BPH).Material and methods: Between January 2015 and April 2019, transurethral plasmakinetic enucleation of the prostate (TUEP) followed by laparoscopic bladder diverticulectomy (LD) were performed in 12 patients at our institution, in four of them combined with bladder stone(s) and in one patient combined with diverticular tumor. Clinical data were retrospectively collected.Results: The mean size of the prostate was 137.3 ± 96.3 (65.5-403.3) ml. The mean maximal diameter of the diverticulum was 8.0 ± 2.7 (3.2-12.0) cm. The mean total operation time was 214.2 ± 69.0 (120-300) min, and the mean enucleation time was 23.2 ± 6.4 (12-35) min. The mean intraoperative blood loss was 52.1 ± 14.9 (30-80) ml. The average pre- and post-operative maximum flow rate was 5.1 ± 1.4 (2.4-8.5) ml/s and 12.8 ± 2.3 (9.6-17.1) ml/s. Except for urinary infection in one patient, no other severe peri- or postoperative complications were observed.Conclusions: TUEP accompanied by LD in one session provides an effective and minimally invasive surgical treatment for bladder diverticula combined with BPH, with or without bladder stones, and permits reasonable operation time and rapid discharge.

Abstract
The International Collaboration on Cancer Reporting (ICCR) is a not for profit organisation whose goal is to produce standardised internationally agreed and evidence-based datasets for pathology reporting. With input from pathologists worldwide, the datasets are intended to be uniform and structured. They include all items necessary for an objective and accurate pathology report which enables clinicians to apply the best treatment for the patient. This dataset has had input from a multidisciplinary ICCR expert panel. The rationale for some items being required and others recommended is explained, based on the latest literature. The dataset incorporates data from the World Health Organization (WHO) 2016, and also from the latest (8th edition) TNM staging system of the American Joint Committee on Cancer (AJCC). Fifteen required elements and eight recommended items are described. This dataset provides all the details for a precise and valuable pathology report required for patient management and prognostication. This dataset is intended for worldwide use, and should facilitate the collection of standardised comparable data on bladder carcinoma at an international level.

Abstract
The aim of this systematic review was to present available data on diagnostic and therapeutic options in intradiverticular bladder tumour cases. A literature search within the Medline database was conducted in March 2019 with combinations of the following search terms: bladder cancer, bladder tumour, bladder diverticulum, diverticulum, intradiverticular. Seventeen relevant articles were identified. Diagnostic and therapeutic options for intradiverticular bladder tumour follow the general management of bladder cancer patients. The most important differences include a higher rate of non-urothelial histology, higher rate of invasive cancers (stage T1 and higher), no stage T2 disease due to lack of a muscularis propria layer and potential role of partial cystectomy or diverticulectomy in the treatment. Among cystectomized patients, the survival is comparable to general bladder cancer patients after cystectomy. Data on accuracy of imaging and endoscopy in diagnosing intradiverticular bladder tumour are poor. There is no study comparing different treatment modalities in intradiverticular bladder tumour patients. Limitations of this review include low number and low evidence level of available studies, as well as low number and heterogeneity of enrolled subjects. Available literature data cannot be the basis for clinical recommendations in intradiverticular bladder tumour cases. While bladder cancer is the most common urinary tract malignancy and at least 1% of cases are intradiverticular, further research in this field is justified.

Abstract
Objectives Studies have shown a high risk of tumor development within a bladder diverticulum (BD). We were interested in the relationship between BD and the development of bladder cancer. Herein, we attempted to investigate whether there exists an association between documented BD and subsequent risk of bladder cancer. Methods We identified 10,662 hospitalized urology patients, including 2,134 documented BD patients (study cohort) and 8,528 non-BD subjects (comparison cohort) from Taiwan’s National Health Insurance database. Only urology patients were enrolled in the study to minimize selection bias. The two cohorts were frequency-matched 1:4 by age, sex and index-year. Patients with less than one year of follow-up were excluded to avoid inverting cause and effect. Risks of developing bladder cancer were estimated using the Cox proportional hazard regression model. Results There was an increased bladder cancer risk in the documented BD patients. The incidence of bladder cancer in documented BD patients was 2.60-fold higher than that in the comparison group, and the overall risk-factor-adjusted hazard ratio was 2.63 (95% CI, 1.74–3.97). Moreover, stratified analysis by sex also showed that documented BD patients were at higher risk of subsequent bladder cancer than the comparison cohort. The effect of BD on the risk of bladder cancer was higher in males than in females and was more profound in patients without comorbidities than in those with comorbidities. Conclusion In this population-based longitudinal study, urology patients with documented BD might have an elevated risk of subsequent bladder cancer. Based on the limitations of the retrospective study design, further studies are required.

Abstract
Non-traumatic urinary bladder emergencies are rare but critical diagnoses to make in an emergency setting. Acute urinary bladder pathologies require an accurate and timely diagnosis to ensure a favorable clinical outcome. Multidetector computed tomography (CT) is the imaging modality of choice for acute and emergent conditions affecting the urinary bladder. MRI is helpful as a problem-solving modality due to better soft tissue characterization and higher in-plane resolution. The purpose of this article is to illustrate the spectrum of urinary bladder emergencies, review the imaging findings, and briefly describe the role of imaging in the evaluation of such patients. Although there are a few cases of bladder emergencies been reported separately, the literature summarizing the spectrum is lacking. The objective of this article is to review the imaging of acute emergencies involving urinary bladder that will help us to think beyond non-specific conclusion in an emergency setting. For the sake of focused discussion, traumatic bladder emergencies will be excluded in this review. In the era of highly image reliant clinical practice, radiologists must be familiar with the diagnostic strategy to approach these entities.

Abstract
Urothelial carcinoma of the urinary bladder is a heterogeneous disease with multiple possible treatment modalities and a wide spectrum of clinical outcome. Treatment decisions and prognostic expectations hinge on accurate and precise staging, and the recently published American Joint Committee on Cancer (AJCC) Staging Manual, 8th edition, should be the basis for staging of urinary bladder tumours. It is unfortunate that the International Union Against Cancer (UICC) 8th edition failed to incorporate new data which is considered in the AJCC 8th edition. Thus, the AJCC 8th edition is the focus of this review. Several critical changes and clarifications are made by the AJCC 8th edition relative to the 7th edition. Although the most obvious changes in the 8th edition are in the N (i.e. perivesical lymph node involvement now classified as N1) and M (i.e. M1 is subdivided into M1a and M1b) categories, several points are clarified in the T category (e.g. substaging of pT1 should be attempted). Further optimisation, however, is required. No particular method of substaging pT1 is formally recommended. In this review, these modifications are discussed, as well as points, which require further study and optimisation.

Abstract
Grading and staging of urothelial neoplasm are the most crucial factors in risk stratification and management; both necessitate optimal accuracy and consistency. Several updates and recommendations have been provided though recent publications of the 4th edition of the World Health Organization classification, the 8th edition of the American Joint Committee on Cancer staging system, and the International Consultation on Urological Diseases-European Association of Urology updates on bladder cancer. Updates and recent studies have provided better insights into and approaches to the challenging scenarios in grading and staging of urothelial neoplasm; however, there remain aspects that need further investigation and refinement.

OBJECTIVES Few studies discussed the link between benign prostatic hyperplasia (BPH) and bladder cancer. We performed this cohort study to investigate whether there is an association between BPH and subsequent risk of bladder cancer. METHODS We identified 35,092 study subjects including 17546 BPH patients and 17546 comparisons from the National Health Insurance database. The comparison cohort was frequency matched with age and index-year. We measured subsequent bladder cancer rates (per 1000 person-years) in two cohorts. Attributable risks (ARs) was calculated based on the bladder cancer rates in two cohorts. The hazard ratios (HRs) and 95% confidence intervals (CIs) for bladder cancer were estimated via Cox proportional hazard regression. RESULTS BPH patients had a higher bladder cancer rate than comparisons (AR = 0.81 per 1000 person-years) and exhibited 4.69- and 4.11-fold increases in bladder cancer risk in the crude and adjusted Cox models, respectively (95% CIs = 4.15-6.99 and 2.70-6.26). The AR was highest in patients aged 65-74 years old (AR = 1.33). BPH patients with chronic kidney disease were at an elevated bladder cancer risk. Regarding the association between bladder cancer and transurethral prostatectomy (TURP), BPH patients who underwent TURP were at a higher risk of bladder cancer (AR = 1.69; HR = 6.17, 95% CI = 3.68-10.3) than those who did not (AR = 0.69; HR = 3.73, 95% CI = 2.43-5.74). CONCLUSIONS In this study, BPH patients were found to have an increased risk of subsequent bladder cancer. Based on the limitations of retrospective nature, further studies are needed.

Abstract
Pathological assessment of bladder cancer is becoming an increasingly complex task owing to the growing availability of molecular data for different histological subtypes and the appreciation of their importance in determining outcomes of neoadjuvant chemotherapy. Urologists are aware of the need to closely collaborate with pathologists, and comprehensive sharing of information is crucial to achieve optimal patient management. Numerous steps towards this goal have been made during the past years. Important advances in the assessment and reporting of grading and staging, especially substaging of pT1 urothelial carcinomas, have been made. As part of the International Collaboration on Cancer Reporting (ICCR), an international expert group has suggested worldwide reporting standards for urothelial lesions. Nevertheless, several issues remain unresolved, for example, regarding the reporting of heterogeneous lesions and substaging as well as the gross handling and the reporting for lymphadenectomy specimens. During the past few years, major insights have been gained into the molecular changes that occur during bladder cancer development, but a consensus on how to integrate these data into daily practice has not been achieved.

Challenges in Pathologic Staging of Bladder Cancer: Proposals for Fresh Approaches of Assessing Pathologic Stage in Light of Recent Studies and Observations Pertaining to Bladder Histoanatomic Variances.

Abstract
The paradigm of pathologic stage (pT) categorization in bladder cancer remains the depth of invasion into the different histologic layers of the bladder wall. However, the approaches to assigning pT stage category toward an enhanced outcome stratification have been marked by challenges and innovations, due in part to our growing appreciation of the surprisingly perplexing bladder histoanatomy. Upstaging of pT1 tumors after radical cystectomy is substantial and underscores the potential value of pT1 substaging in transurethral resection (TUR) specimens. The 2017 American Joint Committee on Cancer tumor-node-metastasis system recommends pT1 substaging but recognizes the need to optimize the approach. Over the years, the cut-off for microinvasion has been significantly lowered to 0.5 mm and is now a promising scheme for pT1 (micrometric) substaging. Unlike the micrometric approach, histoanatomic substaging using muscularis mucosae (MM) and vascular plexus as landmarks is less feasible in TUR specimens and inconsistent in stratifying the outcome of pT1 tumors. The lamina propria possesses inherent variations in depth, MM, and vascular plexus dispositions that should be factored in future pT1 substaging proposals. Histoanatomic variations among the bladder regions also occur, and studies suggest that trigone and bladder neck cancers may have more adverse outcomes. The muscularis propria (MP), besides being the essential histologic landmark for assigning pT2 stage category, is also considered a surrogate for the adequacy of TUR, furthering the importance of identifying its presence in TUR specimens. MP, however, may be mimicked by hyperplastic or isolated MP-like MM muscle bundles in the lamina propria with overstaging implications, and caution should be exercised in distinguishing these 2 muscle types morphologically and immunohistochemically. Presence of additional superficial MP unique from the detrusor muscle proper may also complicate staging at the trigone and ureter insertion sites. With regard to the depth of MP invasion, large and multicenter studies have reaffirmed the prognostic significance of pT2a/b subcategories. It is revealed that there are at least 3 ways used to demarcate the irregular MP to perivesical soft tissue junction, and use of a common criterion indicates improvement in pT2b/pT3a staging reproducibility. Although studies have shown significantly poorer outcome in pT3b compared with pT3a tumors, this designation has a substantial reliance on the prosector's gross assessment of perivesical soft tissue invasion which if performed incorrectly may lead to staging inaccuracy of pT3 tumors. The 8th edition of the American Joint Committee on Cancer has updated the staging schema for bladder cancers with concomitant prostatic stromal invasion and cancers within bladder diverticula. Because of 2 possible pT designations, prostatic stromal invasion in TUR specimens should not be automatically staged as either pT4a or pT2 (urethral). Recent data support that bladder cancer invading into the seminal vesicle has comparable outcome to pT4b tumors. Interestingly, several studies in pT4a tumors, which are staged based on sex-specific organs, have shown poorer outcome in females than males after radical cystectomy, and while there are possibly several reasons, they may also include anatomic factors. Despite the progress has been made, work remains to be done to inform future bladder cancer pT category definitions and their reproducibility in application and prognostication.

Abstract
UNLABELLED It has been 12 yr since the publication of the last World Health Organization (WHO) classification of tumours of the prostate and bladder. During this time, significant new knowledge has been generated about the pathology and genetics of these tumours. Intraductal carcinoma of the prostate is a newly recognized entity in the 2016 WHO classification. In most cases, it represents intraductal spread of aggressive prostatic carcinoma and should be separated from high-grade prostatic intraepithelial neoplasia. New acinar adenocarcinoma variants are microcystic adenocarcinoma and pleomorphic giant cell adenocarcinoma. Modifications to the Gleason grading system are incorporated into the 2016 WHO section on grading of prostate cancer, and it is recommended that the percentage of pattern 4 should be reported for Gleason score 7. The new WHO classification further recommends the recently developed prostate cancer grade grouping with five grade groups. For bladder cancer, the 2016 WHO classification continues to recommend the 1997 International Society of Urological Pathology grading classification. Newly described or better defined noninvasive urothelial lesions include urothelial dysplasia and urothelial proliferation of uncertain malignant potential, which is frequently identified in patients with a prior history of urothelial carcinoma. Invasive urothelial carcinoma with divergent differentiation refers to tumours with some percentage of "usual type" urothelial carcinoma combined with other morphologies. Pathologists should mention the percentage of divergent histologies in the pathology report. PATIENT SUMMARY Intraductal carcinoma of the prostate is a newly recognized entity in the 2016 World Health Organization classification. Better defined noninvasive urothelial lesions include urothelial dysplasia and urothelial proliferation of uncertain malignant potential.

Abstract
This paper reviews recent advances in graphene-based biosensors development in order to obtain smaller and more portable devices with better performance for earlier cancer detection. In fact, the potential of Graphene for sensitive detection and chemical/biological free-label applications results from its exceptional physicochemical properties such as high electrical and thermal conductivity, aspect-ratio, optical transparency and remarkable mechanical and chemical stability. Herein we start by providing a general overview of the types of graphene and its derivatives, briefly describing the synthesis procedure and main properties. It follows the reference to different routes to engineer the graphene surface for sensing applications with organic biomolecules and nanoparticles for the development of advanced biosensing platforms able to detect/quantify the characteristic cancer biomolecules in biological fluids or overexpressed on cancerous cells surface with elevated sensitivity, selectivity and stability. We then describe the application of graphene in optical imaging methods such as photoluminescence and Raman imaging, electrochemical sensors for enzymatic biosensing, DNA sensing, and immunosensing. The bioquantification of cancer biomarkers and cells is finally discussed, particularly electrochemical methods such as voltammetry and amperometry which are generally adopted transducing techniques for the development of graphene based sensors for biosensing due to their simplicity, high sensitivity and low-cost. To close, we discuss the major challenges that graphene based biosensors must overcome in order to reach the necessary standards for the early detection of cancer biomarkers by providing reliable information about the patient disease stage.

Abstract
Carbon based nanomaterials have attracted significant attention over the past decades due to their unique physical properties, versatile functionalization chemistry, and biological compatibility. In this review, we will summarize the current state-of-the-art applications of carbon nanomaterials in cancer imaging and drug delivery/therapy. The carbon nanomaterials will be categorized into fullerenes, nanotubes, nanohorns, nanodiamonds, nanodots and graphene derivatives based on their morphologies. The chemical conjugation/functionalization strategies of each category will be introduced before focusing on their applications in cancer imaging (fluorescence/bioluminescence, magnetic resonance (MR), positron emission tomography (PET), single-photon emission computed tomography (SPECT), photoacoustic, Raman imaging, etc.) and cargo (chemo/gene/therapy) delivery. The advantages and limitations of each category and the potential clinical utilization of these carbon nanomaterials will be discussed. Multifunctional carbon nanoplatforms have the potential to serve as optimal candidates for image-guided delivery vectors for cancer.

Abstract
Background To examine histopathologic features and clinical outcomes of intradiverticular bladder carcinomas. Methods Twenty-two consecutive patients with intradiverticular bladder carcinoma treated with either endoscopic transurethral resection or partial or radical cystectomy at a single institution between years of 1995 to 2011. Clinicopathologic characteristics and oncologic outcomes of patients were retrospectively analyzed, including tissue histology re-review by genitourinary pathologists. Results Histologically, 9 cases (41%) were non-invasive papillary urothelial carcinoma, 13 cases (59%) were invasive urothelial carcinoma, including three cases of small cell carcinoma. Final pathology revealed synchronous extradiverticular urothelial carcinomas in 6 out of 9 cases (67%) of non-invasive and 2 out of 10 cases (20%) invasive intradiverticular urothelial carcinoma, respectively. More than half of cases (13/22, 59%) showed a distinctive hypertrophic layer of muscularis mucosae. There was no statistical difference in disease free survival or overall survival between non-invasive and invasive tumors within approximately 3 years of follow up (mean 38 months, median 32 months). While stage T3 patients generally did poorly, oncologic outcomes for stage T1 patients were no different than those of stage Ta. Conclusion Intradiverticular carcinomas are often associated with a hypertrophic layer of muscularis mucosae that can potentially confound tumor staging. Non-invasive intradiverticular urothelial carcinomas are more likely to have coexisting synchronous extradiverticular lesions. The absence of a muscularis propria layer may not necessarily predispose T1 tumors to more aggressive disease.
