Relapses Rates and Patterns for Pathological T0 After Robot-Assisted Radical Cystectomy: Results From the International Robotic Cystectomy Consortium.

OBJECTIVES: To investigate the oncologic outcomes of pT0 after robot-assisted radical cystectomy (RARC). METHODS: A retrospective review of the International Robotic Cystectomy Consortium database was performed. Patients with pT0 after RARC were identified and analyzed. Data were reviewed for demographics and pathologic outcomes. Kaplan-Meier curves were used to depict recurrence-free survival (RFS), disease-specific survival (DSS), and overall survival (OS). Multivariate stepwise Cox regression models were used to identify variables associated with RFS and OS. RESULTS: Four hundred seventy-one patients (18%) with pT0 were identified. Median age was 68 years (interquartile range (IQR) 60-73), with a median follow up of 20 months (IQR 6-47). Thirty-seven percent received neoadjuvant chemotherapy and 5% had pN+ disease. Seven percent of patients experienced disease relapse; 3% had local and 5% had distant recurrence. Most common sites of local and distant recurrences were pelvis (1%) and lungs (2%). Five-year RFS, DSS, and OS were 88%, 93%, and 79%, respectively. Age (hazards ratio [HR] 1.05, 95% confidence interval [CI] 1.01-1.09, P = 0.02), pN+ve (HR 11.48, 95% CI 4.47-29.49, P < .01), and reoperations within 30 days (HR 5.53, 95% CI 2.08-14.64, P < .01) were associated with RFS. Chronic kidney disease (HR 3.24, 95% CI 1.45-7.23, P < .01), neoadjuvant chemotherapy (HR 0.41, 95% CI 0.18-0.92, P = .03), pN+ve (HR 4.37, 95% CI 1.46-13.06, P < .01), and reoperations within 30 days (HR 2.64, 95% CI, 1.08-6.43, P = .03) were associated with OS. CONCLUSIONS: Despite pT0 status at RARC, 5% had pN+ disease and 7% of patients relapsed. Node status was the variable strongest associated with RFS and OS in pT0.

Multicentre International Study for the Prevention with iAluRil of Radio-induced Cystitis (MISTIC): A Randomised Controlled Study.

BACKGROUND: Radiation-induced cystitis is a common side effect of radiotherapy (RT) to the pelvic area. Hyaluronic acid (HA) and chondroitin sulfate (CS) are components of the urothelial mucosa and positive results have been obtained for intravesical HA/CS instillations for the treatment of urinary tract infections and bladder pain syndrome. HA/CS may also have a protective effect against RT bladder toxicity. OBJECTIVE: To investigate whether HA and CS protect the urothelium during RT, alleviate lower urinary tract symptoms, and improve quality of life. DESIGN SETTING AND PARTICIPANTS: This multicentre randomised controlled trial was conducted across seven centres in four countries. Male patients aged ≥18 yr scheduled to undergo primary intensity-modulated radiotherapy for localised prostate cancer were enrolled. INTERVENTION: Patients were randomised to intravesical HA/CS plus an oral formulation of curcumin, quercetin, HA, and CS (group A) or no treatment (group B). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was absolute changes from baseline to follow-up in urinary domain scores for the Expanded Prostate Cancer Index Composite (EPIC), the International Consultation on Incontinence Questionnaire-Male Lower Urinary Tract Symptoms (ICIQ-MLUTS), and the EuroQol Group EQ-5D-5L questionnaire. Data analysis for efficacy and safety outcomes was performed using an intention-to-treat (ITT) approach; the ITT population was defined as all randomised patients. RESULTS AND LIMITATIONS: Of 57 patients screened, 49 were enrolled and randomly assigned to either active treatment (group A, n = 25) or the control (group B, n = 24). Three patients in the control group withdrew after randomisation. Changes from baseline to 12 mo were worse in the control group for subtotal scores for urinary symptoms and impact of symptoms on quality of life and for the total score (p = 0.05, p = 0.003, and p = 0.008, respectively). There was a significant time × group interaction in favour of active treatment for the incontinence symptom score (p = 0.011) and bother score (p = 0.017). The absence of a sham procedure and/or placebo is the main limitation. CONCLUSIONS: Our results suggest that intravesical HA/CS in combination with an oral formulation may reduce urinary symptoms and improve QoL at short-term (1 yr) follow-up. PATIENT SUMMARY: We investigated whether hyaluronic acid (HA) and chondroitin sulfate (CS) have a protective effect against the bladder toxicity of radiotherapy for prostate cancer. HA/CS used for weekly bladder irrigation for 6 wk and given orally with curcumin and quercetin for 12 wk reduced urinary incontinence symptoms and bother measured at 1-year follow-up. This may hold promise as a preventive treatment if the results are confirmed in further trials.

Evaluation of a remote-controlled laparoscopic camera holder for basic laparoscopic skills acquisition: a randomized controlled trial.

BACKGROUND: Unsteady camera movement and poor visualization contribute to a difficult learning curve for laparoscopic surgery. Remote-controlled camera holders (RCHs) aim to mitigate these factors and may be used to overcome barriers to learning. Our aim was to evaluate performance benefits to laparoscopic skill acquisition in novices using a RCH. METHODS: Novices were randomized into groups using a human camera assistant (HCA) or the FreeHand v1.0 RCH and trained in the (E-BLUS) curriculum. After completing training, a surgical workload questionnaire (SURG-TLX) was issued to participants. RESULTS: Forty volunteers naïve in laparoscopic skill were randomized into control and intervention groups (n = 20) with intention-to-treat analysis. Each participant received up to 10 training sessions using the E-BLUS curriculum. Competency was reached in the peg transfer task in 5.5 and 7.6 sessions for the ACH and HCA groups, respectively (P = 0.015), and 3.6 and 6.8 sessions for the laparoscopic suturing task (P = 0.0004). No significance differences were achieved in the circle cutting (P = 0.18) or needle guidance tasks (P = 0.32). The RCH group experienced significantly lower workload (P = 0.014) due to lower levels of distraction (P = 0.047). CONCLUSIONS: Remote-controlled camera holders have demonstrated the potential to significantly benefit intra-operative performance and surgical experience where camera movement is minimal. Future high-quality studies are needed to evaluate RCHs in clinical practice. TRIAL REGISTRATION: ISRCTN 83733979.

Ten-Year Oncologic Outcomes Following Robot-Assisted Radical Cystectomy: Results from the International Robotic Cystectomy Consortium.

PURPOSE: Radical cystectomy is the gold standard for nonmetastatic muscle invasive bladder cancer and for refractory nonmuscle invasive disease. Compared to open radical cystectomy, robot-assisted radical cystectomy has been shown to provide comparable early oncologic outcomes and improved perioperative outcomes. However, there is a paucity of data on long-term oncologic outcomes and concerns about a higher incidence of local recurrence after robot-assisted radical cystectomy. We report 10-year oncologic outcomes following robot-assisted radical cystectomy using a multinational database. MATERIALS AND METHODS: We retrospectively reviewed the prospective International Robotic Cystectomy Consortium database. Consecutive patients who underwent robot-assisted radical cystectomy 10 years ago or earlier were included in analysis. Data were reviewed for demographics, and perioperative, pathological and oncologic outcomes. Kaplan-Meier curves were used to depict recurrence-free, disease specific and overall survival. Multivariate stepwise Cox regression models were applied to identify variables associated with recurrence-free, disease specific and overall survival. RESULTS: We identified 446 patients with a median age of 67 years (IQR 59-76). Of the patients 10% received neoadjuvant chemotherapy, 51% experienced any complication, 23% had high grade complications and 4% died within 3 months of robot-assisted radical cystectomy. Disease was pT3 or greater in 43% of patients and pN+ in 24% while a positive soft tissue surgical margin was observed in 7%. At a median followup of 5 years (IQR 2-10, maximum 14) local and distant recurrence had developed in 15% and 29% of patients, respectively. Ten-year recurrence-free, disease specific and overall survival rates were 59%, 65% and 35%, respectively. Patients with pT3 or greater and pN+ disease showed worse recurrence-free, disease specific and overall survival. CONCLUSIONS: Long-term oncologic outcomes, and recurrence rates and patterns after robot-assisted radical cystectomy seem comparable to those in open series. Advanced disease stage and positive surgical margins remain the main determinants of survival after radical cystectomy.

European Association of Urology Section of Urolithiasis (EULIS) Consensus Statement on Simulation, Training, and Assessment in Urolithiasis.

BACKGROUND: Simulation-based training offers an acceptable adjunct to the traditional mentor-apprentice model in helping trainees to traverse the early stages of the learning curve for ureteroscopy and percutaneous renal surgery. In addition, nontechnical skills are increasingly important in preventing adverse events in the operating room, and simulation-based training can be used for training in such skills. Incorporation of simulation into formalised, standardised, and validated curricula offers an applicable method for training residents. OBJECTIVE: To develop a curriculum for urolithiasis procedures incorporating technical and nontechnical skills training for implementation across Europe. DESIGN, SETTING, AND PARTICIPANTS: An international panel of experts from EULIS, EUREP, ESU and ESUT was consulted in five stages. The study incorporated a mix of qualitative and quantitative data for collection and analysis. Responses were drawn out in (1) an opinion survey and (2) a curriculum development survey, which were discussed in (3) a focus group meeting. Group responses from this meeting were analysed for themes, which were discussed at (4) a focus group meeting, where consensus was reached among the group. Data analysis and integration at this stage were used to draft the curriculum. RESULTS AND LIMITATIONS: All group meetings were transcribed from the focus group discussion. Eight themes were generated, into which all data were categorised. These were: need for a training curriculum; curriculum objectives; curriculum structure; curriculum content; teaching platforms and tools; assessment and certification; validation and implementation; and global integration of the curriculum. A curriculum, including recommended simulators for use, was subsequently proposed. CONCLUSIONS: We propose a comprehensive curriculum for training in urolithiasis. Additional planning is required for full validation and implementation before it can be used to train residents. PATIENT SUMMARY: Stone disease accounts for a major proportion of surgical interventions worldwide. We describe a consensus guideline for effective training of stone surgeons.

Hexaminolevulinate-guided fluorescence cystoscopy in the diagnosis and follow-up of patients with non-muscle-invasive bladder cancer: review of the evidence and recommendations.

CONTEXT: Compared with standard white-light cystoscopy, photodynamic diagnosis with blue light and the photosensitiser hexaminolevulinate has been shown to improve the visualisation of bladder tumours, reduce residual tumour rates by at least 20%, and improve recurrence-free survival. There is currently no overall European consensus outlining specifically where hexaminolevulinate is or is not indicated. OBJECTIVE: Our aim was to define specific indications for hexaminolevulinate-guided fluorescence cystoscopy in the diagnosis and management of non-muscle-invasive bladder cancer (NMIBC). EVIDENCE ACQUISITION: A European expert panel was convened to review the evidence for hexaminolevulinate-guided fluorescence cystoscopy in the diagnosis and management of NMIBC (identified through a PubMed MESH search) and available guidelines from across Europe. On the basis of this information and drawing on the extensive clinical experience of the panel, specific indications for the technique were then identified through discussion. EVIDENCE SYNTHESIS: The panel recommends that hexaminolevulinate-guided fluorescence cystoscopy be used to aid diagnosis at initial transurethral resection following suspicion of bladder cancer and in patients with positive urine cytology but negative white-light cystoscopy for the assessment of tumour recurrences in patients not previously assessed with hexaminolevulinate, in the initial follow-up of patients with carcinoma in situ (CIS) or multifocal tumours, and as a teaching tool. The panel does not currently recommend the use of hexaminolevulinate-guided fluorescence cystoscopy in patients for whom cystectomy is indicated or for use in the outpatient setting with flexible cystoscopy. CONCLUSIONS: Evidence is available to support the use of hexaminolevulinate-guided fluorescence cystoscopy in a range of indications, as endorsed by an expert panel.

[Metastasic urethral squamous-cell a cancer]. / Carcinoma escamoso de uretra metastático.

Urethral cancer is an infrequent pathology, less than 1% of the genitourinary tumors. It is more frequent in women (4:1), in the sixth or seventh decade of life. The most frequent histology being squamous cell carcinoma. First signs and symptoms usually are more attributable to benign stricture disease, rather than malignicy. The interval between the onset of symptoms and diagnosis may be as long as three years. Therefore most of these tumors are locally advanced at the time of diagnosis with generally poor prognosis despite aggressive treatment. Therapeutic management varies with the stage and location of the lesion. Because of the rarity of this pathology, no consensus has been reached on treatment modalities, but seems to be that must be a multimodal one, including surgery, radiotherapy and chemotherapy. We present the case of an 80 year-old male, with a diagnosis of urethral squamous-cell cancer, locally advanced at the time of diagnosis. Surgery was not feasible. The patient underwent chemotherapy and radiotherapy with evidence of quick progression thereafter.

EAU guidelines for the management of urogenital schistosomiasis.

More than 100 million people worldwide are affected by bilharziasis, caused by Schistosoma haematobium. For travellers precaution is most important. For the population in endemic areas, an integrated approach including health education is necessary. Effective pharmacologic treatment is available.

EAU guidelines for the management of genitourinary tuberculosis.

Nearly one third of the world's population is estimated to be infected with Mycobacterium tuberculosis. Moreover, tuberculosis is the most common opportunistic infection in AIDS patients. Genitourinary tuberculosis is not very common but it is considered as a severe form of extra-pulmonary tuberculosis The diagnosis of genitourinary tuberculosis is made based on culture studies by isolation of the causative organism; however, biopsy material on conventional solid media may occasionally be required. Drug treatment is the first line therapy in genitourinary tuberculosis. Treatment regimens of 6 months are effective in most of the patients. Although chemotherapy is the mainstay of treatment, surgery in the form of ablation or reconstruction may be unavoidable. Both radical and reconstructive surgery should be carried out in the first 2 months of intensive chemotherapy.
