RESUMEN
BACKGROUND: Radical cystectomy is associated with considerable morbidity and mortality. Based on the solid evidence in colorectal surgery, fast-track/ERAS® (Enhanced Recovery After Surgery) protocols have been developed to improve the perioperative management of patients undergoing radical cystectomy. OBJECTIVES: To review the literature and guidelines and evaluate the evidence regarding the different components of ERAS® protocols. MATERIALS AND METHODS: Systemic literature search and evaluation of relevant guidelines. RESULTS: The majority of ERAS® recommendations for radical cystectomy are based on extrapolations of abdominal surgery studies. Four randomized, controlled trials and one ERAS® guideline were published for radical cystectomy. ERAS® seems to shorten length of stay without increasing the complication rate. Key elements are no bowel preparation, no nasogastric tube, optimized fluid substitution, multimodal pain management, early mobilization, and oral diet. CONCLUSIONS: Implementation of ERAS® requires multidisciplinary collaboration. Individualization of an ERAS® program, identification of the most important components and adaption to the specific needs of radical cystectomy patients are future goals.

PURPOSE: The evaluation of the potential clinical benefit of four-dimensional ultrasound (4D-US) in the assessment of bladder cancer (BC). MATERIAL AND METHODS: 20 patients with indication for cystoscopy for suspicion of bladder cancer were prospectively included in this study. All patients underwent two-dimensional ultrasound (2D-US), contrast enhanced ultrasound (CEUS) and real-time four-dimensional ultrasound (4D-US). All acquisitions were compared to each other in regard to image quality. This assessment was done using a 6 point scale (1â=âbest). All patients underwent subsequently cystoscopy with resection of the tumor (TURB), due a histopathological analysis was possible. RESULTS: All examinations were performed successfully and no patient had to be excluded from the study. Patients acceptance of 4D-US was consistently good. No adverse events occurred. Image quality of real time 4D-US (score: 1.27±0.46) was significantly superior (pâ<â0.001) to both, conventional 2D-US (score: 2.33±0.62) and also to 2D-CEUS (score: 2.00±0.53). In terms of tumor detection no superiority was evident for 4D-US compared to 2D-US or in utilization of CEUS (sensitivityâ=â0.89; specificityâ=â1.00; positive predictive valueâ=â1.00; negative predictive valueâ=â0.50; AUCâ=â0.944; (95% CI: 07.43-0.998)). CONCLUSION: The assessment of bladder cancer using real time 4D-US is feasible and improves the image quality and therefore also the precise anatomical consistency of intravesical tumor masses.

OBJECTIVES: According to current guidelines, radical cystectomy (RC) should be combined with an extended pelvic lymphadenectomy (PLND) as therapeutic and staging instrument. Objective of this study was to analyze the influence of PLND on survival rates and complication rates in a selected group of elderly patients with a minimum age of 80 years. MATERIALS AND METHODS: In this single-center retrospective analysis, we evaluated 102 patients who underwent RC due to UCB from 2004 to 2015 at our institution. In 74 patients (73%), RC was combined with PLND; in 28 cases (27%), RC was performed without PLND. Impact of PLND on cancer specific survival (CSS), overall survival (OS) and progression-free survival (PFS) was analyzed using log-rank test and COX regression model. RESULTS: In univariate analysis of the data, we were not able to show a significant impact of PLND on CSS (p = 0.606), OS (p = 0.979) or PFS (p = 0.883). Also in multivariate analysis of the data, we were not able to identify PLND as an independent prognostic parameter on survival rates of patients undergoing RC, neither for CSS (p = 0.912) nor OS (p = 0.618) or PFS (p = 0.900). CONCLUSIONS: Our small and single-center study was not able to demonstrate a significant independent influence of PLND on CSS, OS and PFS in octogenarians undergoing RC due to UCB. There is no doubt that RC should usually be combined with PLND, but the results of this small data set with a selected patient cohort indicate that RC without PLND might be an option in selected cases of elderly patients.

INTRODUCTION: Urothelial carcinoma of the bladder is known as one of most common malignant tumors in the urogenital tract. Non-muscle invasive bladder cancer (NMIBC) in particular has a high recurrence rate and results in correspondingly high costs for the public health system. METHODS: To improve the recurrence rate and the prognosis of NMIBC the diagnosis, resection technique, adjuvant instillation therapy and exact histopathological classification of tumor lesions are indispensable. This article gives an overview on the current developments in this field. RESULTS: The current European Association of Urology (EAU) guidelines and the preliminary version of the German S3 guidelines on bladder cancer list photodynamic diagnosis (PDD) and narrow band imaging (NBI) as diagnostic procedures for tumors of the bladder. The trend for resection of bladder tumors is towards the use of en bloc resection using various techniques. Furthermore, an update of the WHO classification aims at a better identification and prognosis of the different risk groups of NMIBC. CONCLUSION: The treatment of NMIBC can only be improved by the combination of optimized diagnosis, precise tumor resection, improved adjuvant intravesical therapy and correct histopathological evaluation of tumors.
