Migration of double-J ureteral stent in patients with ureteroileal anastomosis stricture undergoing radical cystectomy and orthotopic neobladder: Analysis risk factors of stent migration. Medicine (Baltimore) 2024; 103:e37765. [PMID: 38640312 PMCID: PMC11030022 DOI: 10.1097/md.0000000000037765] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 02/29/2024] [Accepted: 03/08/2024] [Indexed: 04/21/2024] Open
Abstract
The objective was to evaluate the incidence and degree of double-J ureteral stent (DJUS) migration. Additionally, we aimed to investigate the risk factors associated with stent migration in the orthotopic neobladder group. In this retrospective study, 61 consecutive patients were included; 35 patients (45 DJUS placements) underwent radical cystectomy with orthotopic neobladder and 26 patients (35 DJUS placements) underwent urinary bladder without cystectomy between July 2021 and March 2023. All the patients were treated with a DJUS for ureteric strictures. The technical success rate was 100% in each group. The DJUS migration was significantly higher in the orthotopic neobladder group, with 22 of 45 cases (48.9%), compared to the urinary bladder group, which had 4 of 35 cases (11.4%) (P ≤ .001). Among the patients in the orthotopic neobladder group who experienced DJUS migration, stent dysfunction occurred in 18 cases (81.8%), which was statistically significant (P = .003). Multivariate logistic regression analysis revealed that only the size of the DJUS was significantly and positively associated with migration (odds ratio:10.214, P = .010). DJUS migration can easily occur in patients undergoing radical cystectomy and orthotopic neobladder, and smaller stent sizes are associated with a higher incidence of migration.

[PMID: 38613698 PMCID: PMC11015994 DOI: 10.1007/s00432-024-05684-8] [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: 02/02/2024] [Accepted: 03/04/2024] [Indexed: 04/15/2024]
Abstract
OBJECTIVE To date, there have been few studies examining the prognostic implications of histological subtypes in ureteral cancer. And chemotherapy plays a crucial role in the treatment of ureteral cancer, while many factors influence the efficacy of chemotherapy. This study aimed to utilize the Surveillance, Epidemiology and End Results database to assess the impact of histological type on ureteral cancer prognostic outcomes and discovered how histological type and T-stage influence the efficacy of chemotherapy. METHODS Based on Surveillance, Epidemiology, and End Results Program, we reviewed 8915 records of patients with primary ureteral cancer from 18 centers between 2000 and 2018. We focused on the overall survival and cancer-specific survival of the records and used Kaplan‒Meier method to calculate survival curves. RESULTS In the comparison of prognostic outcomes, atypical subtypes exhibited a less favorable prognosis compared to typical ureteral carcinoma. Notably, patients diagnosed with papillary urothelial carcinoma demonstrated the most favorable overall survival (p = 0.005). Statistically significant benefits were observed in the prognosis of patients with non-papillary urothelial carcinoma who received chemotherapy (HR = 0.860, 95% CI 0.764-0.966, p = 0.011), while chemotherapy did not yield a statistically significant effect on the prognosis of patients with papillary urothelial carcinoma (HR = 1.055, 95% CI 0.906-1.228, p = 0.493). Chemotherapy had an adverse impact on the prognosis of patients with T1 ureteral cancer (HR = 1.235, 95% CI 1.016-1.502, p = 0.034), whereas it exhibited a positive prognostic effect for T3/T4 cases (HR = 0.739, 95% CI 0.654-0.835, p < 0.001). CONCLUSIONS Histological type affects the prognosis of ureteral cancer. And evaluation of cancer histological type and T stage in ureteral cancer patients prior to chemotherapy is mandatory.

Varma M, Dormer J. Macroscopy of specimens from the genitourinary system. J Clin Pathol 2024; 77:177-183. [PMID: 38373783 DOI: 10.1136/jcp-2023-208831] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Accepted: 09/12/2023] [Indexed: 02/21/2024]
Abstract
Macroscopic specimen examination is often critical for accurate histopathology reporting but has generally received insufficient attention and may be delegated to inexperienced staff with limited guidance and supervision. This review discusses issues around macroscopic examination of some common urological specimens; highlighting findings that are critical for patient management and others that are clinically irrelevant. Macroscopic findings are of limited value in completely submitted radical prostatectomy specimens but may be critical in orchidectomy specimens where identification of focal non-seminomatous components can significantly impact patient management. The maximum tumour dimension is often an important prognostic indicator, but specimen dimensions are generally of little clinical utility. Specimens should be carefully examined and judiciously sampled to identify clinically important focal abnormalities such as sarcomatoid change in a renal cell carcinoma and a minor non-seminomatous component in a predominant testicular seminoma. Meticulous macroscopic examination is key as less than 0.2% of the specimen (or macroscopically abnormal area) would be histologically examined even if the entire specimen/abnormal area is submitted for microscopic examination. Retroperitoneal pelvic lymph node dissection specimens for testicular cancer must be handled very differently from other lymph nodal block dissections. Current sampling protocols for transurethral resection of prostate specimens that are based on pre-MRI era data need to be reconsidered because they were specifically designed to detect occult prostate cancer, which would amount to histological cancer screening. Prostatic sampling of cystoprostatectomy specimens should be directed at accurately staging the known bladder cancer rather than detection of incidental prostate cancer.

A Systematic Review and Meta-Analysis of Clinicopathologic Factors Predicting Upper Urinary Tract Recurrence After Radical Cystectomy for Urothelial Bladder Cancer. Clin Genitourin Cancer 2022; 21:317-323. [PMID: 36513557 DOI: 10.1016/j.clgc.2022.11.002] [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: 06/03/2022] [Revised: 11/04/2022] [Accepted: 11/05/2022] [Indexed: 11/15/2022]
Abstract
To identify risk factors for upper urinary tract recurrence (UUTR) in patients treated with radical cystectomy (RC) for urothelial bladder carcinoma (UBC). The PubMed, Web of Science, and Cochrane Library were searched on March 2022 to identify relevant studies according to the Preferred Reporting Items for Systematic Review (PRISMA) statement. We included studies that provided multivariate logistic regression analyses. The pooled UUTR rate was calculated using a fixed effect model. We identified 235 papers, of which seven and 6 articles, comprising a total of 8981 and 8404 UBC patients, were selected for qualitative and quantitative analyses, respectively. Overall, 418 (4.65%) patients were diagnosed with UUTR within a median time of 1.4 to 3.1 years after RC. Risk factors for UUTR were surgical margin (hazard ratio [HR] 3.41, 95% confidence interval [CI] 2.59-4.49, P < .00001), preoperative hydronephrosis (HR: 1.74, 95% CI: 1.25-2.43, P = .001), ureteral margin (HR: 4.34, 95% CI: 2.75-6.85, P < .00001), and pT stage (HR: 2.69, 95% CI: 1.37-5.27, P < .004). Incorporation of established risk factors into a clinical prediction model might aid in the decision-making process regarding the intensity and type of surveillance protocols after RC as well as help determine the pretest probability of UUTR.

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
CONTEXT The question of the ability of frozen section analysis (FSA) to accurately detect malignant pathology intraoperatively has been discussed for many decades. OBJECTIVE We aimed to conduct a systematic review and meta-analysis assessing the diagnostic estimates of FSA of the urethral and ureteral margins in patients treated with radical cystectomy (RC) for bladder cancer (BCa). EVIDENCE ACQUISITION The MEDLINE and EMBASE databases were searched in February 2021 for studies analyzing the association between FSA and the final urethral and ureteral margin status in patients treated with RC for BCa. The primary endpoint was the value of pathologic detection of urethral and ureteral malignant involvement with FSA during RC compared with the final margin status. We included studies that provided true positive, true negative, false positive, and false negative values for FSA, which allowed us to calculate the diagnostic estimates. EVIDENCE SYNTHESIS Fourteen studies, comprising 8208 patients, were included in the quantitative synthesis. Forest plots revealed that the pooled sensitivity and specificity for FSA of urethral margins during RC were 0.83 (95% confidence interval [CI] 0.38-0.97) and 0.95 (95% CI 0.91-0.97), respectively. While for the FSA of ureteral margins, the pooled sensitivity and specificity were 0.77 (95% CI 0.67-0.84) and 0.97 (95% CI 0.95-0.98), respectively. Calculated diagnostic odds ratios indicated high FSA effectiveness, and patients with a positive urethral or ureteral margin at final pathology are over 100 times more likely to have positive FSA than patients without margin involvement at final pathology. Area under the curves of 96.6% and 96.7% were reached for FSA detection of urethral and ureteral tumor involvement, respectively. CONCLUSIONS Intraoperative FSA demonstrated high diagnostic performance in detecting both urethral and ureteral malignant involvement at the time of RC for BCa. FSA of both urethral and ureteral margins during RC is accurate enough to be of great value in the routine management of BCa patients treated with RC. While its specificity was great to guide intraoperative decision-making, its sensitivity remains suboptimal yet. PATIENT SUMMARY We believe that the frozen section analysis of both urethral and ureteral margins during radical cystectomy should be considered more often in urologic practice, until quality of life-based cost-effectiveness studies can identify patients within each institution who are unlikely to benefit from it.

Abstract
The cornerstone for diagnosis and treatment of bladder and upper tract urothelial carcinoma involves surgery. Transurethral resection of bladder tumors forms the basis of further management. Radical cystectomy for invasive bladder carcinoma provides good oncologic outcomes. However, it can be a morbid procedure, and advances such as minimally invasive surgery and early recovery after surgery need to be incorporated into routine practice. Diagnostic ureteroscopy for upper tract carcinoma is needed in cases of doubt after cytology and imaging studies. Low-risk cancers can be managed with conservative endoscopic surgery without compromising oncological outcomes; however, high-risk disease necessitates radical nephroureterectomy.

Abstract
OBJECTIVE Achieving negative status of distal ureteral margin at the time of radical cystectomy (RC), and its therapeutic benefit, remains controversial. The aim of this review was to evaluate frequency, reliability and impact of positive distal ureteral margin after radical cystectomy for bladder cancer on upper tract recurrence, cancer specific and overall survival, and to identify best candidates for intraoperative frozen section analyses. MATERIAL AND METHODS A systemic review was performed following the PRISMA guideline. PubMed/Medline (with following terms; bladder cancer or cystectomy and frozen section or ureteral margin), and Cochrane Library were searched up to April 2020, to identify all papers evaluating distal ureteral margin and discussing clinical interest. Previous reviews and single case reports were excluded. RESULTS In total, thirty-two relevant studies were identified. Mean rate of positive ureteral frozen section after RC was close to 10% [1.1-25.4%]. Frozen section (FS) achieved a very good specificity [83-100%] and reserved sensibility [45-100%]. In many cases, an initial positive margin on FS can be converted to negative. Positive FS and/or PS (permanent section) were associated with upper urinary tract recurrence (UUTR). Conversion from positive FS to negative PS was associated with low UUTR frequency and better cancer survival in large retrospective studies. The relevant prognostic factor associated with positive FS and/or PS was CIS within the bladder. CONCLUSION FS should be recommended for patients with CIS within the bladder. Achieving negative FS/PS might be associated with lower rates of UUTR and better survival, for patients with higher life expectancy. Prospective randomized controlled studies need to be performed to provide definitive recommendations in this area.

Abstract
Since their introduction into clinical practice in the 1950s, ileal conduits have been the most common type of urinary diversion used after radical cystectomy worldwide. Although ileal conduits are technically simpler to construct than other forms of urinary diversion, a variety of complications can occur in the early and late postoperative periods. Early complications include urine leakage, urinary obstruction, postoperative fluid collection (eg, urinoma, hematoma, lymphocele, or abscess), and fistula formation. Late complications include ureteroileal anastomotic stricture, stomal stenosis, conduit stenosis, and urolithiasis. Although not directly related to ileal conduits, ureteroarterial fistula can occur in patients with an ileal conduit. Interventional radiologists can play a pivotal role in diagnosis and management of these complications by performing image-guided minimally invasive procedures. In this article, the authors review the surgical anatomy of an ileal conduit and the underlying pathophysiology of and diagnostic workup for complications related to ileal conduits. The authors also discuss and illustrate current approaches to interventional radiologic management of these complications, with emphasis on a collaborative approach with urologists or endourologists to best preserve patients' renal function and maintain their quality of life. ©RSNA, 2020.

Abstract
Objective To summarise the currently available literature and analyse available results of the outcome of intraoperative frozen-section analysis (FSA) on upper urinary tract recurrence (UUTR) after radical cystectomy (RC). Materials and methods A systematic review of the literature was performed according to the Cochrane Reviews guidelines and in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Articles discussing ureteric FSA with RC were identified. Results The literature search yielded 21 studies, on which the present analysis was done. The studies were published between 1997 and 2019. There were 10 010 patients with an age range between 51 and 95 years. Involvement of the ureteric margins was noted in 2–9% at RC. The sensitivity and specificity of FSA were ~75% and 99%, respectively. Adverse pathology on FSA and on permanent section, prostatic urothelial carcinoma involving the stroma but not prostatic duct, and ureteric involvement on permanent section were all more likely to develop UUTR. Neither evidence of ureteric involvement nor ureteric margin status on permanent section were significant predictors of overall survival. Conclusion Routine FSA is mandatory for a tumour-free uretero–enteric anastomosis and is predictive of UUTR. To lower the UUTR, FSA is not necessary if the ureters are resected at the level where they cross the common iliac vessels. FSA is indicated whenever the surgeon encounters findings suspicious of malignancy, e.g. ureteric obstruction, periureteric fibrosis, diffuse carcinoma in situ, induration or frank tumour infiltration of the distal ureter is discovered unexpectedly during surgery, and prostatic urethral involvement. Abbreviations CIS: carcinoma in situ; FSA: frozen-section analysis; HR: hazard ratio; PRISMA: Preferred Reporting Items for Systematic Reviews and Meta-Analyses; RC: radical cystectomy; (UT)UC: (upper tract) urothelial carcinoma; UUT(R): upper urinary tract (recurrence)

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
AIM To determine the usefulness of the frozen section exams of lymph nodes dissection, ureteral and urethral section during radical cystectomy for urothelial carcinoma and define the impact on the surgical procedure. METHOD A retrospective, single-center study of data collected from 182 patients who underwent radical cystectomy for an cT=3bN0M0 urothelial bladder cancer between 2016 and 2018. Bladder cancer extension was determined by thoracoabdominal CT with contrast enhancement and urography and an 18-FDG PET scanner. No patient received neoadjuvant chemotherapy. The diagnostic performance of the frozen section exams was related to final examinations. The impact of the result on the initial intervention was determined. RESULTS The frozen section were positive in 29 lymph nodes dissections (15.9 %), 59 (16.6 %) ureteral and 20 (10.9 %) ureteral recessions. With lymph nodes exams, sensitivity, specificity and positive and negative predictive values were 93.5 %, 100 %, 100 %, and 98.7 %, respectively. With ureteral sections exams the same values were 91.5 %, 100 %, 100 %, and 98.4 % respectively. With urethral section exams, all the values were of 100 %. Finally, all the procedure has been modified for all patients with positive frozen section exam except one positive urethral section that did not give rise to radical urethrectomy. CONCLUSION Frozen section exams were useful to the urologist during radical cystectomy for urothelial carcinoma. The performances of the frozen section exams carried out were excellent. The information of the urologist of the positive frozen section leeds to modify its management during the intervention in all the studied cases with the exception of one case.

Abstract
Objective To identify primary tumour-related factors at transurethral resection of bladder tumour (TURBT) that may predict positive distal ureteric margins (PUM) at the time of radical cystectomy (RC). Patients and methods A retrospective, cohort study was conducted using our institution's data from June 2007 to June 2016. Patients who underwent TURBT followed by RC for non-metastatic urothelial carcinoma (UC) of the bladder were identified. In all, 211 patients underwent RC for UC during the study period. The patients were divided into two groups: Group-I (n = 17) with PUM and Group-II (n = 194) with negative ureteric margins. Univariate and multivariate analyses were performed to determine the predictors of PUM. Results On univariate analysis, multifocality, tumours involving the ureteric orifice, trigonal tumours, presence of carcinoma in situ (CIS), and lymphovascular invasion at TURBT, were significantly more common in Group-I. On multivariate analysis, tumour involvement in the ureteric orifice(s) and presence of associated CIS significantly predicted PUM. Conclusions Primary tumour-related factors on initial TURBT that predicted PUM (at RC) were involvement of the ureteric orifice(s) and presence of associated CIS. These results may help to select patients who can be selectively offered intraoperative frozen section analysis.

Abstract
BACKGROUND The clinical significance of the plasmacytoid variant (PCV) in urothelial carcinoma (UC) is currently lacking. OBJECTIVE To compare clinical outcomes of patients with any PCV with that of patients with pure UC treated with radical cystectomy (RC). DESIGN, SETTING, AND PARTICIPANTS We identified 98 patients who had pathologically confirmed PCV UC and 1312 patients with pure UC and no variant history who underwent RC at our institution between 1995 and 2014. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Univariable and multivariable Cox regression and Cox proportional hazards regression to determine if PCV was associated with overall survival (OS). RESULTS AND LIMITATIONS Patients with PCV UC were more likely to have advanced tumor stage (p=0.001), positive lymph nodes (p=0.038), and receive neoadjuvant chemotherapy than those with pure UC (46% vs 22%, p<0.0001). The rate of positive soft tissue surgical margins was over five times greater in the PCV UC group compared with the pure UC group (21% vs 4.1%, respectively, p<0.0001). Median OS for the pure UC versus the PCV patients were 8 yr and 3.8 yr, respectively. On univariable analysis, PCV was associated with an increased risk of overall mortality (hazard ratio=1.34, 95% confidence interval: 1.02-1.78, p=0.039). However, on multivariable analysis adjusted for age, sex, neoadjuvant chemotherapy received, lymph node status, pathologic stage, and soft margin status, the association between PCV and OS was no longer significant (hazard ratio=1.06, 95% confidence interval: 0.78, 1.43, p=0.7). This retrospective study is limited by the lack of pathological reanalysis, and the impact of other concurrent mixed histology cannot be determined in this study. CONCLUSIONS Patients with PCV features have a higher disease burden at RC compared with those with pure UC. However, PCV was not an independent predictor of survival after RC on multivariable analysis, suggesting that PCV histology should not be used as an independent prognostic factor. PATIENT SUMMARY Plasmacytoid urothelial carcinoma is a rare and aggressive form of bladder cancer. Patients with plasmacytoid urothelial carcinoma had worse adverse pathologic features, but this was not associated with worse overall mortality when compared with patients with pure urothelial carcinoma.

Abstract
CONTEXT Urothelial carcinoma is considered a pan-urothelial disease. As such, the remnant urothelium in the upper urinary tract and urethra following radical cystectomy (RC) remains at risk for secondary urothelial tumors (SUTs). OBJECTIVE To describe the incidence, diagnosis, treatment, and outcomes of patients with SUTs after RC. EVIDENCE ACQUISITION A systematic search was conducted using PubMed database according to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines to identify studies between 1970 and 2016 reporting on malignant diseases of the urothelium after RC for bladder cancer. The search strategy separated between upper and lower tract urothelial tumors. EVIDENCE SYNTHESIS Of a total of 1069 studies, 57 were considered for evidence synthesis. SUTs occured in approximately 4-10% of patients after RC. Carcinoma in situ of the bladder, a history of nonmuscle invasive bladder cancer, and tumor involvement of the distal ureter are the strongest risk factors for secondary upper tract tumors. Risk factors for secondary urethral tumors represent urothelial malignancy in the prostatic urethra/prostate and bladder neck (in women), nonorthotopic diversions, and positive findings on permanent sections. The majority of patients (84%) with SUTs, presented with urothelial recurrence without evidence of metastasis. Of those, 84.0% were treated with surgery, 10.5% with systemic chemotherapy and/or radiotherapy, and 5.6% with topical chemotherapy and/or immunotherapy. After a median follow-up of 91 mo (range: 26-155), 65.9% of patients died of disease and 21.5% died of other causes. Detection and treatment of SUTs at an asymptomatic stage can reduce the risks of cancer-specfific and overall mortality by 30%. A limitation of the study is that the available data were retrospective. CONCLUSIONS SUTs are rare oncological events and most patients have an adverse prognosis despite absence of distant disease at diagnosis. Therefore, surveillance of the remnant urothelium should be implemented for patients with histological features of panurothelial disease as it may improve timely detection and treatment. PATIENT SUMMARY Secondary tumors of the renal pelvis, ureters, and urethra occur in approximately 4-10% of patients after radical removal of the bladder for bladder cancer. These patients' prognoses are reduced, likely due to delayed diagnosis. Therefore, routine surveillance might be important to detect tumors at an early stage.

Abstract
OBJECTIVE To assess the utility of routine frozen section analysis of ureters at the time of radical cystectomy (RC) for urothelial cancer (UC), and the long-term outcomes of adverse ureteric pathology. PATIENTS AND METHODS Pathological data on 2 047 patients undergoing RC for UC with routine frozen section analysis of ureters (January 1971 to December 2009) were analysed. Univariate and multivariable logistic and Cox proportional hazards models were used to determine the risk of upper tract UC (UTUC) recurrence, local recurrence and overall survival in those identified as having adverse pathology (severe atypia/carcinoma in situ [CIS] or UC) at time of frozen section analysis. RESULTS Adverse pathology was identified by frozen section analysis in 178 patients (8.6%). Frozen section analysis was found to have poor sensitivity in identifying adverse pathology (59.1%), which was improved in patients with preoperative CIS (68.0%). After a median (interquartile range) follow-up of 12.4 (1.9-10.1) years, 28 patients (1.4%) developed UTUC recurrence. There were no uretero-enteric anastomotic recurrences. Adverse pathology on frozen section analysis was associated with UTUC recurrence on univariate analysis (hazard ratio [HR] 6.2, 95% confidence interval [CI] 2.9-13.5), but 15/28 patients (54%) with UTUC recurrence had benign ureteric frozen section analysis on initial sectioning. Adverse pathology on frozen section analysis was not independently associated with the risk of local recurrence (HR 1.08, 95% CI 0.61-1.89) or overall survival (HR 1.12, 95% CI 0.94-1.35) in multivariate models. CONCLUSIONS Ureteric frozen section analysis has poor sensitivity and may be marginally improved in pre-existing CIS. UTUC recurrence is rare and can occur despite negative frozen section analysis. Our data question the utility of routine frozen section analysis of the distal ureteric margin at the time of RC.

Abstract
The first two authors contributed equally to this work Classification of upper tract urothelial preneoplastic and neoplastic lesions mirrors that of the urinary bladder, with all lesions of the bladder urothelium being possible in the upper tract and vice versa. There are three major groups of non-invasive urothelial neoplasms: flat, papillary, and inverted. These three groups share a similar morphological spectrum of intraurothelial changes, ranging from hyperplasia to dysplasia to carcinoma in situ. However, they differ in terms of architectural growth pattern compared to the surrounding non-neoplastic mucosal surface. Infiltrating urothelial carcinoma is defined as a urothelial tumor that invades beyond the basement membrane. Unlike in non-invasive papillary urothelial neoplasms (pTa), the role of histologic grade in pT1 and higher stage tumors has been suggested to be of only relative importance. The vast majority of tumors of the upper urinary tract are urothelial carcinoma. More commonly seen, however, are foci of squamous differentiation and, less frequently, glandular differentiation. Pure urothelial carcinomas also display a wide range of variant morphologies, and recognition of these morphologies is important for diagnosis, classification, and prognosis.

Abstract
Objective The aim of this study is to examine the incidence and risk factors of upper urinary tract recurrence (UUTR) following radical cystectomy (RC) in bladder cancer and to evaluate its relationship with neobladder (Neo) or ileal conduit (IC). Materials and Methods All clinicopathologic parameters and perioperative parameters of 311 patients who underwent RC with either Neo or IC by a single surgeon from 1999 to 2012 were retrospectively included in this study. Patients with a history of renal surgery, concomitant UUTR, or a histopathology of non-transitional cell carcinoma were excluded. For statistical analyses of predictive risk factors of UUTR, a multivariate analysis was performed with known risk factors of UUTR, including type of urinary diversion with significance defined as P < 0.05. Results During the median follow-up period of 53 months, 143 (46.0%) IC and 168 (54.0%) Neo were performed, resulting in 11 (3.5%) cases of UUTR (Neo 7 and IC 4) after RC and all patients then underwent nephroureterectomy. No significant differences in incidence and overall survival in UUTR were observed according different types of urinary diversion (p = 483), and the prognosis for survival of Neo was insignificantly better than that of IC (5-year overall survival 78% vs 74%, respectively, p>0.05). Higher number of positive lymph nodes (HR 9.03) and the presence of pelvic local recurrence (HR 7286.08) were significant predictive factors of UUTR (p<0.05). Conclusion This study reports a UUTR rate of 3.5%, and positive lymph nodes and presence of local recurrence at the pelvis as important risk factors. No significant differences in incidence and survival were observed between Neo and IC.

Abstract
OBJECTIVE To assess the incidence and clinical significance of 'skip lesions' that are present in proximal but not in distal ureteric sections, which are occasionally found during the pathological examination of ureteric margins during radical cystectomy (RC). PATIENTS AND METHODS We identified 660 patients who underwent a RC and had at least two permanent margins for a given ureter. In all, 1173 ureters were analysed and classified as follows: 'normal' (no tumour, reactive atypia, mild or moderate dysplasia) or 'abnormal' (severe dysplasia, carcinoma in situ (CIS), or tumour). Transitions from 'normal' distal pathology to 'abnormal' on proximal section(s) determined frequency of skip lesions. Fisher's exact test and the log-rank test were used to study correlations. RESULTS Ureteric skip lesions were found in 4.8% patients (2.9% ureters). Pathology of skip lesions was CIS in 55.9%, transitional cell carcinoma in 23.5% and severe dysplasia in 20.6%. Skip lesions were associated with lymphovascular invasion (34.4% vs 13.7%, P = 0.004) and advanced pT stage (P = 0.007). On multivariate analysis, skip lesions correlated with lower median overall survival (OS) (inestimable vs 8.2 years, P = 0.014) in patients with pT0 or pTa disease and a trend towards lower OS (2.7 vs 8.8 years, P = 0.066) in pTis disease. Concordance between frozen distal margin and permanent proximal margin varied; sensitivity was 80% in those without and 20% in those with skip lesions. CONCLUSIONS The presence of a ureteric skip lesion may be associated with lower survival in patients with pT0, pTa or pTis urothelial carcinoma. Thus, while uncommon, ureteric skip lesions should be reported in pathological findings.

Abstract
OBJECTIVES This study was designed to establish an individualized selection strategy for the two most common types of ureteroenteric anastomotic techniques (Bricker and Wallace anastomosis) used in ileal conduit (IC) diversion. METHODS Patients who underwent IC diversion after radical cystectomy for transitional cell carcinoma between January 2009 and December 2011 were prospectively collected. The choice of anastomosis type (Bricker vs. Wallace) was successively based on tumor characteristics, ureteral anomalies, and ureteral length after retrosigmoidal tunneling. RESULTS Ninety-nine patients were enrolled in the final study. Fifty-three patients underwent Bricker anastomosis, and 46 underwent Wallace anastomosis. Ureteral stricture developed in 6 (6.1 %) patients and the overall stricture rate for all ureters was 3.1 % (6/196). Strictures occurred at an average of 13.3 months after surgery and were predominately located in the left ureter (66.7 %, 4/6). The difference in the ureter stricture rates between the two groups was not statistically significant: 3.8 % (4/104) and 2.2 % (2/92) for Bricker and Wallace, respectively (p = 0.686). There were no significant differences in age, sex, body mass index (BMI), prevalence of pelvic radiation therapy, length of stay, follow-up time, or time to stricture between the two techniques. Patients in whom stricture developed had a significantly higher mean BMI compared with those without stricture (25.2 vs. 23.3 kg/m(2), respectively; p = 0.008). CONCLUSIONS Our preliminary outcomes demonstrate that this selection strategy of Bricker vs. Wallace anastomosis seems to be clinically reliable, providing an acceptable low ureteral stricture rate of 3.1 %. However, the potential advantage for oncologic control of this strategy is needed to further confirm.

Abstract
The authors found that duplicated ureters was not a contraindication to robot-assisted laparoscopic radical cystoprostatectomy in this case. Objectives: Ureteric duplication is a rarely seen malformation of the urinary tract more commonly seen in females. Materials and Methods: We report 2 cases of robot-assisted laparoscopic radical cystoprostatectomy (RALRCP) with bilateral extended pelvic lymph node dissection and intracorporeal Studer pouch formation in patients with duplicated right ureters. Results: Two male patients (53 and 68 years old) underwent transurethral resection of a bladder tumor that revealed high-grade muscle invasive transitional cell carcinoma, with no metastases. We performed RALRCP and intracorporeal Studer pouch formation. A duplicated right ureter was observed during the procedures in both patients. Left ureter distal segment was spatulated 2cm long and anastomosed using running 4/0 Vicryl to the right ureter at its bifurcation where it forms a single lumen without spatulation. All 3 ureters were catheterized individually. A Wallace type uretero-ileal anastomosis was performed between the ureters and the proximal part of the Studer pouch chimney. Although ureteric frozen section analysis suggested ureteric carcinoma in situ in patient 1, postoperative pathologic evaluation was normal. Frozen section and final postoperative pathologic evaluations were normal in patient 2. Conclusions: Duplicated ureters might be underdiagnosed on CT. The presence of a duplicated ureter is not a contraindication to RALRCP and intracorporeal Studer pouch formation. The da Vinci-S surgical robot is very safe for performing this complicated procedure. Frozen section analysis of ureters during radical cystectomy for bladder cancer might not reliably diagnose the pathologic condition and might overestimate the disease in the ureters.

Abstract
BACKGROUND We hypothesized that the incidence of ureteral abnormalities on frozen section analysis (FS) at the time of radical cystectomy is much lower than historical values and that FS has minimal impact on outcomes. We also sought to determine the accuracy of FS and the associated costs. METHODS We reviewed the records of 301 patients who underwent a radical cystectomy for urothelial carcinoma of the bladder (UC) between March 2000 and January 2007. The ureteral margins were sent for FS and subsequent permanent hematoxyllin and eosin (H&E) sections and results were compared. Analyses were performed to determine the costs of FS and if any association was present with the pathological stage of the primary bladder tumour and regional lymph nodes, the presence of urothelial carcinoma in situ of the bladder (CIS) and survival outcomes with the FS. RESULTS We identified 602 ureters for this study. The incidence of CIS or solid urothelial carcinoma in the ureter was 2.8%. The presence of CIS of the bladder and prostatic urethra was significantly associated with a positive FS (p = 0.02). The FS were not associated with survival outcomes. The cost to pick up 1 patient with any abnormality on FS was $2080. The cost to pick up 1 patient with CIS or solid urothelial carcinoma of the ureter on FS was $6471. CONCLUSION The incidence of CIS and tumour on FS during radical cystectomy for UC is low. The costs associated with FS are substantial. Frozen section analysis should only be performed in select patients undergoing radical cystectomy.

Abstract
Urothelial carcinoma in situ (CIS) is regarded as a precursor of invasive bladder carcinoma. Although relatively uncommon as a primary entity, CIS is frequently seen in conjunction with other bladder tumors and represents a significant source of difficulty for surveillance of patients with known bladder cancer. CIS lesions are difficult to detect by cystoscopic examination or by currently available screening markers. Urothelial CIS is infrequently reported in the literature as a primary process; however, a wide variety of emerging methodologies are becoming available for screening and follow-up of bladder cancer. Most new methods demonstrate sensitivity and specificity similar to the current standard of urine cytology and cystoscopy. Detection of high-grade lesions such as CIS by these methods appears generally better than detection of low-grade lesions. Current molecular evidence suggests that a spectrum of genetic aberrations including p53 mutations are strongly associated with the potentially invasive CIS phenotype in contrast to low-grade papillary and hyperplastic lesions. These low-grade lesions frequently recur but infrequently become invasive. Patients with high-grade lesions including CIS and high-grade papillary tumors warrant aggressive treatment and life-long surveillance.

Abstract
OBJECTIVE Inadequate tumor margin status in cervical cancer and pre-cancer patients is associated with repeat procedures and an increased risk of recurrence and progression. This review will outline information regarding the current treatment options for women who wish to maintain fertility, the methods currently used in practice to evaluate tumor margin involvement, and a look at potential solutions to this critical issue. METHOD We performed a PUBMED literature search of relevant research articles pertaining to tumor margin evaluation for multiple cancers, current treatment options for patients of cervical dysplasia and the effects of those treatments on fertility. RESULTS Previous studies have correlated cancer recurrence and progression to obtaining clear margins upon resection. The most common need to obtain clear margins with respect to conservative treatment in patients with cervical neoplasia occurs with women who wish to preserve fertility. However, current detection methods are limited and current treatments present additional fertility concerns. CONCLUSION In order to provide the best care for patients wishing to retain fertility post-treatment for cervical dysplasia, a superior option for detecting tumor margins accurately at the microscopic scale must be further explored.

Abstract
Urothelial carcinoma is characterized by multiple, multifocal recurrences throughout the genitourinary tract; approximately 3% of patients treated by radical cystectomy (RC) for invasive transitional cell carcinoma (TCC) of the bladder will subsequently develop a subsequent TCC in the upper urinary tract (UUT) urothelium. Metachronous upper UUT tumours (mUUT-TCC) typically occur as a late oncological event (>3 years after RC). The vast majority of mUUT-TCCs are detected only after the progression to tumour-related symptoms, e.g. haematuria, flank pain or pyelonephritis, despite strict adherence to surveillance protocols. Failure of imaging and cytology to detect most asymptomatic tumours has led to questions about the need for routine UUT surveillance. Some authors have advocated a more tailored approach to surveillance after RC, targeting high-risk patients and with limiting imaging in those patients at lowest risk of developing a subsequent UUT-TCC. mUUT-TCCs are most common in patients with TCC in the ureter or urethra, and with organ-confined bladder cancer. Although the prognosis is generally poor, long-term survival can be achieved in a subset of patients after radical nephroureterectomy (NU). Minimally invasive techniques, e.g. ureteroscopic and percutaneous resection, have been proposed as renal-sparing alternatives to radical surgery for patients with low-stage and -grade de novo UUT-TCC. However, oncological control of renal-sparing therapies in those with high-risk mUUT-TCC remains largely unconfirmed. Until oncological outcomes equivalent to the standard, radical NU, are reported in patients after RC, conservative treatment strategies should be avoided.

Abstract
PURPOSE Risk factors for upper tract recurrence following radical cystectomy for transitional cell carcinoma of the bladder are not yet well-defined. We reviewed our population of patients who underwent radical cystectomy to identify prognostic factors and clinical outcomes associated with upper tract recurrence. MATERIALS AND METHODS From our prospective database of 1,359 patients who underwent radical cystectomy we identified 1,069 patients treated for transitional cell carcinoma of the bladder between January 1985 and December 2001. Univariate analysis was completed to determine factors predictive of upper tract recurrence. RESULTS A total of 853 men and 216 women were followed for a median of 10.3 years (maximum 18.5). There were 27 (2.5%) upper tract recurrences diagnosed at a median of 3.3 years (range 0.4 to 9.3). Only urethral tumor involvement was predictive of upper tract recurrence. In men superficial transitional cell carcinoma of the prostatic urethra was associated with an increased risk of upper tract recurrence compared with prostatic stromal invasion or absence of prostatic transitional cell carcinoma (p <0.01). In women urethral transitional cell carcinoma was associated with an increased risk of upper tract recurrence (p = 0.01). Despite routine surveillance 78% of upper tract recurrence was detected after development of symptoms. Median survival following upper tract recurrence was 1.7 years (range 0.2 to 8.8). Detection of asymptomatic upper tract recurrence via surveillance did not predict lower nephroureterectomy tumor stage, absence of lymph node metastases or improved survival. CONCLUSIONS Patients with bladder cancer are at lifelong risk for late oncological recurrence in the upper tract urothelium. Patients with evidence of tumor involvement within the urethra are at highest risk. Surveillance regimens frequently fail to detect tumors before symptoms develop. However, radical nephroureterectomy can provide prolonged survival.
