Cost-effectiveness of quality improvement intervention to reduce time between CT-detection and ureteroscopic laser fragmentation in acute symptomatic ureteric stones management.

OBJECTIVE: To prospectively assess clinical and cost effectiveness of emergency ureteroscopic laser fragmentation of urinary stones causing symptoms or obstruction. PATIENTS AND METHODS: 100 consecutive patients with an average (median) age 55.6 (57.5) years and average (median) stone size of 8.2 mm (± 7 mm) between October 2018 and December 2021 who underwent emergency ureteroscopy and laser fragmentation formed the study cohort as part of a clinical service quality improvement. Primary outcome was single procedure stone-free rate and cost-effectiveness. The secondary outcomes were complications, re-admission and re-intervention. A decision analysis model was constructed to compare the cost-effectiveness of emergency ureteroscopy with laser fragmentation (EUL) and emergency temporary stenting followed by delayed ureteroscopy with laser fragmentation (DUL) using our results and success rates for modelling. RESULTS: Single procedure stone-free rates (SFR) for EUL and DUL were 85%. The re-intervention rate, re-admission and complication rates of the study cohort (EUL) were 9%, 18%, and 4%, respectively, compared to 15%, 20%, and 5%, respectively for the control cohort (DUL). The decision analysis modelling demonstrated that the EUL treatment option was more cost-efficient, averting £2868 (€3260) per patient for the UK health sector. Total cost of delayed intervention was £7783 (€8847) for DUL in contrast to £4915 (€5580) for EUL. CONCLUSIONS: Implementation of quality improvement project based on a reduction in CT detection-to-laser fragmentation time interval in acute ureteric obstruction or symptoms caused by stones had similar clinical effectiveness compared to delayed ureteroscopic management, but more cost-effective.

Comparative Assessment of Different Ultrasound Technologies in the Detection of Prostate Cancer: A Systematic Review and Meta-Analysis.

The present study aimed to assess the diagnostic test accuracy of different ultrasound scanning technologies in the detection of prostate cancer. A systematic search was conducted using the Cochrane Guidelines for Screening and Diagnostic Tests. We performed a systematic search in the international databases PubMed, Medline, Ovid, Embase and Cochrane Library. Searches were designed to find all studies that evaluated Micro-US, mpUS, SWE and CEUS as the main detection modalities for prostate cancer. This study was registered with Research Registry of systematic review and meta-analysis. The QUADAS-2 tool was utilized to perform quality assessment and bias analysis. The literature search generated 1376 studies. Of these, 320 studies were screened for eligibility, with 1056 studies being excluded. Overall, 26 studies with a total of 6370 patients met the inclusion criteria. The pooled sensitivity for grayscale, CEUS, SWE, Micro-US and mpUS modalities were 0.66 (95% CI 0.54-0.73) 0.73 (95% CI 0.58-0.88), 0.82 (95% CI 0.75-0.90), 0.85 (95% CI 0.76-0.94) and 0.87 (95% CI 0.71-1.03), respectively. Moreover, the pooled specificity for grayscale, CEUS, SWE, Micro-US and mpUS modalities were 0.56 (95% CI 0.21-0.90), 0.78 (95% CI 0.67-0.88), 0.76 (95% CI 0.65-0.88), 0.43 (95% CI 0.28-0.59) and 0.68 (95% CI 0.54-0.81), respectively. In terms of sensitivity, substantial heterogeneity between studies was detected (I2 = 72%, p = 0.000 < 0.05). In relation to specificity, extreme heterogeneity was detected (I2 = 93%, p = 0.000 < 0.05). Some studies proved that advanced ultrasound modalities such as mpUS, Micro-US, shear-wave elastography, contrast enhanced and micro-ultrasound are promising methods for the detection of prostate cancer.

Urinary bladder recurrences following ureteroscopic biopsies of upper tract urothelial cancers: a multi-centre observational study with genomic assessment for clonality.

BACKGROUND AND AIMS: Urinary bladder recurrences (UBRs) after radical nephroureterectomy (RNUx) are a known challenge in patients with upper-tract urothelial cancers (UTUCs). We aim to assess factors associated with UBR and clonal-relatedness with resected UTUC. METHODS: Patients who underwent RNUx for UTUC between 1998 and 2015 in five institutions were identified. Clonal relatedness between primary UTUC and subsequent UBR in a sub-cohort was assessed using next-generation sequencing. A Kaplan-Meier curve was used to assess differences in UBR between two groups (with or without ureteroscopic biopsy). RESULTS: Of 267 patients with complete records, 73 (27.3%) had UBR during follow-up. The five-year UBR-free survival in all patients was 64.7%. The five-year UBR-free-survival was inferior in patients who underwent URS biopsy compared with patients who did not undergo ureteroscopic biopsy (49.9% vs 76.4%, p < 0.001). History of bladder tumour (HR, 95% CI; 2.94, 1.73-5.00, p < 0.001), ureteroscopic biopsy (HR, 95% CI; 2.21, 1.38-3.53, p = 0.001) and preoperative urine cytology ≥C3 (HR, 95% CI; 2.06, 1.24-3.40, p = 0.005) were independently associated with UBR. Patients with ureteroscopic biopsy (n = 3/5) showed identical mutational changes for common genes (TP53 and FGFR3) between primary UTUC and subsequent UBR. CONCLUSIONS: Ureteroscopic biopsy of UTUC is a significant risk factor for UBR. Qualitative clonality assessment showed identical mutational signatures between primary UTUC and UBR.

Photodynamic versus white-light-guided resection of first-diagnosis non-muscle-invasive bladder cancer: PHOTO RCT.

BACKGROUND: Around 7500 people are diagnosed with non-muscle-invasive bladder cancer in the UK annually. Recurrence following transurethral resection of bladder tumour is common, and the intensive monitoring schedule required after initial treatment has associated costs for patients and the NHS. In photodynamic diagnosis, before transurethral resection of bladder tumour, a photosensitiser that is preferentially absorbed by tumour cells is instilled intravesically. Transurethral resection of bladder tumour is then conducted under blue light, causing the photosensitiser to fluoresce. Photodynamic diagnosis-guided transurethral resection of bladder tumour offers better diagnostic accuracy than standard white-light-guided transurethral resection of bladder tumour, potentially reducing the chance of subsequent recurrence. OBJECTIVE: The objective was to assess the clinical effectiveness and cost-effectiveness of photodynamic diagnosis-guided transurethral resection of bladder tumour. DESIGN: This was a multicentre, pragmatic, open-label, parallel-group, non-masked, superiority randomised controlled trial. Allocation was by remote web-based service, using a 1 : 1 ratio and a minimisation algorithm balanced by centre and sex. SETTING: The setting was 22 NHS hospitals. PARTICIPANTS: Patients aged ≥ 16 years with a suspected first diagnosis of high-risk non-muscle-invasive bladder cancer, no contraindications to photodynamic diagnosis and written informed consent were eligible. INTERVENTIONS: Photodynamic diagnosis-guided transurethral resection of bladder tumour and standard white-light cystoscopy transurethral resection of bladder tumour. MAIN OUTCOME MEASURES: The primary clinical outcome measure was the time to recurrence from the date of randomisation to the date of pathologically proven first recurrence (or intercurrent bladder cancer death). The primary health economic outcome was the incremental cost per quality-adjusted life-year gained at 3 years. RESULTS: We enrolled 538 participants from 22 UK hospitals between 11 November 2014 and 6 February 2018. Of these, 269 were allocated to photodynamic diagnosis and 269 were allocated to white light. A total of 112 participants were excluded from the analysis because of ineligibility (n = 5), lack of non-muscle-invasive bladder cancer diagnosis following transurethral resection of bladder tumour (n = 89) or early cystectomy (n = 18). In total, 209 photodynamic diagnosis and 217 white-light participants were included in the clinical end-point analysis population. All randomised participants were included in the cost-effectiveness analysis. Over a median follow-up period of 21 months for the photodynamic diagnosis group and 22 months for the white-light group, there were 86 recurrences (3-year recurrence-free survival rate 57.8%, 95% confidence interval 50.7% to 64.2%) in the photodynamic diagnosis group and 84 recurrences (3-year recurrence-free survival rate 61.6%, 95% confidence interval 54.7% to 67.8%) in the white-light group (hazard ratio 0.94, 95% confidence interval 0.69 to 1.28; p = 0.70). Adverse event frequency was low and similar in both groups [12 (5.7%) in the photodynamic diagnosis group vs. 12 (5.5%) in the white-light group]. At 3 years, the total cost was £12,881 for photodynamic diagnosis-guided transurethral resection of bladder tumour and £12,005 for white light. There was no evidence of differences in the use of health services or total cost at 3 years. At 3 years, the quality-adjusted life-years gain was 2.094 in the photodynamic diagnosis transurethral resection of bladder tumour group and 2.087 in the white light group. The probability that photodynamic diagnosis-guided transurethral resection of bladder tumour was cost-effective was never > 30% over the range of society's cost-effectiveness thresholds. LIMITATIONS: Fewer patients than anticipated were correctly diagnosed with intermediate- to high-risk non-muscle-invasive bladder cancer before transurethral resection of bladder tumour and the ratio of intermediate- to high-risk non-muscle-invasive bladder cancer was higher than expected, reducing the number of observed recurrences and the statistical power. CONCLUSIONS: Photodynamic diagnosis-guided transurethral resection of bladder tumour did not reduce recurrences, nor was it likely to be cost-effective compared with white light at 3 years. Photodynamic diagnosis-guided transurethral resection of bladder tumour is not supported in the management of primary intermediate- to high-risk non-muscle-invasive bladder cancer. FUTURE WORK: Further work should include the modelling of appropriate surveillance schedules and exploring predictive and prognostic biomarkers. TRIAL REGISTRATION: This trial is registered as ISRCTN84013636.

Around 7500 people are diagnosed with early-stage bladder cancer in the UK each year. Early bladder cancer is contained within the bladder and has not yet invaded the bladder's muscle wall or spread elsewhere in the body. The cancer will return (recur) in around half of people after initial treatment and they have to attend hospital for regular check-ups, with costs to both them and the NHS. The first step in treating early bladder cancer is surgery to remove the tumour. This surgery is normally performed under white light. Photodynamic diagnosis is a new technique in which a liquid is put into the patient's bladder before surgery and a blue light is used during the operation. This causes the bladder cancer to fluoresce so that it can be seen more easily by the surgeon. The Photodynamic versus white-light-guided resection of first diagnosis non-muscle-invasive bladder cancer ( PHOTO ) trial aimed to find out whether or not using photodynamic diagnosis at initial surgery would reduce how often the cancer recurred and whether or not this could reduce the cost of treating early bladder cancer. A total of 538 people with early bladder cancer who had a medium to high chance of their cancer returning after treatment were enrolled in the PHOTO trial. They were included in one of two treatment groups, at random: 269 had photodynamic surgery and 269 had standard white-light surgery. People in both groups were monitored regularly for any recurrences, with further treatment as appropriate. After 3 years, 4 out of 10 people in each group had a recurrence of their bladder cancer. We found no difference between the treatment groups in the number of people with recurrences. We found no evidence of a benefit to patients, and the total costs of photodynamic surgery were higher than those of standard white light. We therefore recommend that it is no longer used in the treatment of this group of patients.

Cost-Effectiveness of Prostate Cancer Detection in Biopsy-Naïve Men: Ultrasound Shear Wave Elastography vs. Multiparametric Diagnostic Magnetic Resonance Imaging.

This exploratory study investigates the cost-effectiveness of ultrasound shear wave elastography (SWE) imaging in comparison to pre-biopsy multiparametric magnetic resonance imaging (mpMRI) in men with suspected prostate cancer. This research is motivated by the early evidence of the good performance of SWE in distinguishing cancerous from benign prostate tissues. We used a decision analysis model representing the care-pathways of men referred with a high prostate specific antigen (PSA) and/or abnormal digital rectal examination (DRE) in a UK setting from the payer's perspective with results reported in 2016 GBP. We then appraised the cost-effectiveness of a novel approach based on SWE compared to the more conventional and widely practiced mpMRI-based approaches using data reported in the literature. Deterministic and probabilistic sensitivity analyses were used to address uncertainty regarding the parameter values utilised. Our exploratory results implied that SWE approach yielded an additional quality-adjusted life year (QALY) at the cost of GBP 10,048 compared to the standard mpMRI-based approach in the UK. This is lower than the official willingness to pay threshold of GBP 20,000 (the UK healthcare system guidelines) and is therefore a suitable replacement for the current practice. Sensitivity analyses confirmed the robustness of our results.

A Randomized Trial of PHOTOdynamic Surgery in Non-Muscle-Invasive Bladder Cancer.

BACKGROUND: Recurrence of non­muscle-invasive bladder cancer (NMIBC) is common after transurethral resection of bladder tumor (TURBT). Photodynamic diagnosis (PDD) provides better diagnostic accuracy and more complete tumor resection and may reduce recurrence. However, there is limited evidence on the longer-term clinical effectiveness and cost-effectiveness of PDD-guided resection. METHODS: In this pragmatic, open-label, parallel-group randomized trial conducted in 22 U.K. National Health Service hospitals, we recruited participants with a suspected first diagnosis of NMIBC at intermediate or high risk for recurrence on the basis of routine visual assessment before being listed for TURBT. Participants were assigned (1:1) to PDD-guided TURBT or to standard white light (WL)­guided TURBT. The primary clinical outcome was time to recurrence at 3 years of follow-up, analyzed by modified intention to treat. RESULTS: A total of 538 participants were enrolled (269 in each group), and 112 participants without histologic confirmation of NMIBC or who had had cystectomy were excluded. After 44 months' median follow-up, 86 of 209 in the PDD group and 84 of 217 in the WL group had recurrences. The hazard ratio for recurrence was 0.94 (95% confidence interval [CI], 0.69 to 1.28; P=0.70). Three-year recurrence-free rates were 57.8% (95% CI, 50.7 to 64.2) and 61.6% (95% CI, 54.7 to 67.8) in the PDD and WL groups, respectively, with an absolute difference of −3.8 percentage points (95% CI, −13.37 to 5.59) favoring PDD. Adverse events occurred in less than 2% of participants, and rates were similar in both groups, as was health-related quality of life. PDD-guided TURBT was £876 (95% CI, −766 to 2518; P=0.591) more costly than WL-guided TURBT over a 3-year follow-up, with no evidence of a difference in quality-adjusted life years (−0.007; 95% CI, −0.133 to 0.119; P=0.444). CONCLUSIONS: PDD-guided TURBT did not reduce recurrence rates, nor was it cost-effective compared with WL at 3 years.

Real-Time 3D Tracking of Laparoscopy Training Instruments for Assessment and Feedback.

Assessment of minimally invasive surgical skills is a non-trivial task, usually requiring the presence and time of expert observers, including subjectivity and requiring special and expensive equipment and software. Although there are virtual simulators that provide self-assessment features, they are limited as the trainee loses the immediate feedback from realistic physical interaction. The physical training boxes, on the other hand, preserve the immediate physical feedback, but lack the automated self-assessment facilities. This study develops an algorithm for real-time tracking of laparoscopy instruments in the video cues of a standard physical laparoscopy training box with a single fisheye camera. The developed visual tracking algorithm recovers the 3D positions of the laparoscopic instrument tips, to which simple colored tapes (markers) are attached. With such system, the extracted instrument trajectories can be digitally processed, and automated self-assessment feedback can be provided. In this way, both the physical interaction feedback would be preserved and the need for the observance of an expert would be overcome. Real-time instrument tracking with a suitable assessment criterion would constitute a significant step towards provision of real-time (immediate) feedback to correct trainee actions and show them how the action should be performed. This study is a step towards achieving this with a low cost, automated, and widely applicable laparoscopy training and assessment system using a standard physical training box equipped with a fisheye camera.

Endoscopic surgical simulation using low-fidelity and virtual reality transurethral resection simulators in urology simulation boot camp course: trainees feedback assessment study.

OBJECTIVES: The objective of our study was to study trainees' feedback and rating of models for training transurethral resection of bladder lesions (TURBT) and prostate (TURP) during simulation. METHODS: The study was performed during the ''Transurethral resection (TUR) module" at the boot camp held in 2019. Prior to the course, all trainees were required to evaluate their experience in performing TURBT and TURP procedures. Trainees simulated resection on two different models; low-fidelity tissue model (Samed, GmBH, Dresden, Germany) and virtual reality simulator (TURPMentor, 3D Systems, Littleton, US). Following the completion of the module, trainees completed a questionnaire using a 5-point Likert scale to evaluate their assessment of the models for surgical training. RESULTS: In total, 174 simulation assessments were performed by 56 trainees (Samed Bladder-40, Prostate-45, TURPMentor Bladder-51, Prostate-37). All trainees reported that they had performed < 50 TUR procedures. The Samed model median scores were for appearance (4/5), texture (5/5), feel (5/5) and conductibility (5/5). The TURPMentor median score was for appearance (4/5), texture and feel (4/5) and conductibility (4/5). The most common criticism of the Samed model was that it failed to mimic bleeding. In contrast, trainees felt that the TURPMentor haptic feedback was inadequate to allow for close resection and did not calibrate movements accurately. CONCLUSIONS: Our results demonstrate that both forms of simulators (low-fidelity and virtual reality) were rated highly by urology trainees and improve their confidence in performing transurethral resection and in fact complement each other in providing lower tract endoscopic resection simulation.

Global Assessment of Urological Endoscopic Skills (GAUES): development and validation of a novel assessment tool to evaluate endourological skills.

OBJECTIVE: To develop and evaluate an assessment tool for endourological skills during simulation including cystoscopy, ureteroscopy (URS) and transurethral resection (TUR) procedures. METHODS: We designed a Global Assessment of Urological Endoscopic Skills (GAUES) tool, comprised of nine endourology task-specific and two global-rating skills items. The tool was developed through two rounds of the Delphi process. The GAUES tool was used to assess acquisition of URS and TUR skills of novices (Year 2 core surgical trainees, CT2) and intermediate level trainees (residents at the start of the UK higher surgical training programme in Urology, Speciality Trainee Year 3, ST3) at the Urology Simulation Boot Camp (USBC) between 2016 and 2018. Validity was evaluated by comparing scores between trainees with different levels of urological experience. Inter-rater reliability was also assessed. RESULTS: We evaluated 130 residents, 52% of trainees were at an intermediate stage of training and 39% were novices. In all, 9% of the anonymous forms were missing demographics. The completion rate of the GAUES tool during the USBC for URS and TUR was 85% and 89%, respectively. Our analysis demonstrated a significant difference in all domains between intermediates and novices at assessment in URS, except for one domain more suited to clinical assessment (P = 0.226). There was excellent intraclass correlation (ICC) overall between the two experts' judgements, ICC = 0.841 (95% confidence interval 0.767-0.893; P < 0.001, n = 88). CONCLUSIONS: We have developed the novel GAUES tool for cystoscopic, URS and TUR skills. Overall, we demonstrated good face, content and construct validity and excellent reliability, suggesting that the GAUES tool can be useful for endourological skills assessment.

Photodynamic versus white light-guided treatment of non-muscle invasive bladder cancer: a study protocol for a randomised trial of clinical and cost-effectiveness.

INTRODUCTION: Bladder cancer is the most frequently occurring tumour of the urinary system. Ta, T1 tumours and carcinoma in situ (CIS) are grouped as non-muscle invasive bladder cancer (NMIBC), which can be effectively treated by transurethral resection of bladder tumour (TURBT). There are limitations to the visualisation of tumours with conventional TURBT using white light illumination within the bladder. Incomplete resections occur from the failure to identify satellite lesions or the full extent of the tumour leading to recurrence and potential risk of disease progression. To improve complete resection, photodynamic diagnosis (PDD) has been proposed as a method that can enhance tumour detection and guide resection. The objective of the current research is to determine whether PDD-guided TURBT is better than conventional white light surgery and whether it is cost-effective. METHODS AND ANALYSIS: PHOTO is a pragmatic multicentre randomised controlled trial (open parallel group, non-masked and superiority trial) comparing the intervention of PDD-guided TURBT with standard white light resection in newly diagnosed intermediate and high risk NMIBC within the UK National Health Service setting. Clinical effectiveness is measured with time to recurrence. Cost-effectiveness is assessed within trial via the calculation of incremental cost per recurrence avoided and incremental cost per quality-adjusted life per year gained over 3 years and over long term through a modelling exercise over patients' lifetime. ETHICS AND DISSEMINATION: Formal ethics review was undertaken with a favourable opinion, in line with UK regulatory procedures (REC reference number: 14/NE/1062). If reductions in time to recurrence is associated with long-term patient benefits, the cost-effectiveness evaluation will provide further evidence to inform adoption of the technology. Findings will be shared in lay media such as patient and charity forums and will be presented at key meetings and published in academic literature.Trial registration number ISRCTN84013636.

Unmet Supportive Care Needs of Men With Locally Advanced and Metastatic Prostate Cancer on Hormonal Treatment: A Mixed Methods Study.

BACKGROUND: Men affected by prostate cancer who are undergoing hormone therapy can endure a range of symptoms that can adversely affect quality of life. Little research has been conducted to date, to understand the specific unmet supportive care needs of this patient group within the context of current service delivery. OBJECTIVE: The aim of this study was to understand the experiences of unmet supportive care needs of men affected by prostate cancer on hormone therapy in the United Kingdom. METHODS: Mixed methods study recruited 31 men with ≥T3 prostate Cancer or worse and treated by hormone therapy. A small cross-sectional survey (European Organization for Research and Treatment of Cancer [EORTC] C30 and PR25, Self-Management Self-Efficacy Scale, and the Supportive Care Needs Survey) was used to inform the interview schedule. Semi-structured interviews were conducted, and framework approach was used to analyze the data. RESULTS: Complex unmet supportive care needs that were related to physical, psychological/emotional, intimacy/sexual, practical, health system/informational, existential, and patient/clinician communication needs are experienced. Men articulated that current healthcare delivery is failing to provide a holistic person-centered model of care. CONCLUSION: This is one of the few studies that have identified the unmet supportive care needs of men receiving hormone therapy for ≥T3 prostate Cancer or worse. The needs are multiple and far-ranging. IMPLICATIONS FOR PRACTICE: Despite national cancer reforms, unmet supportive care needs persist. The findings from this study may be central in the re-design of future services to optimize men's quality of life and satisfaction with care. Clinicians are encouraged to use these finding to help them optimize care delivery and individual quality of life.

Assessment of Yangtze Finless Porpoises (Neophocaena asiaorientalis) through Biochemical and Hematological Parameters.

Ghulam Nabi, Yujiang Hao, Xianyuan Zeng, and Ding Wang (2017) For the management of endangered species, a periodic health assessment is important, as diet in captivity is restricted due to cost and some nutrients are lost during the processing, storage and thawing of sh. The objective of this study was to compare and assess the nutritional, as well as the physiological health of both the captive and free-ranging Yangtze Finless Porpoises (YFPs) through biochemical markers, selected electrolytes, enzymes and hematological parameters. Our results showed statistically significantly (P < 0.05) higher levels of some biochemical markers (HDL-c/LDL-c, globulin, TP, Urea, Creatinine and BUN), enzymes (GGT), electrolytes (K+, Na+, PO4 3- and Mg2+) and hematological (WBCs, lymphocytes, eosinophil) parameters in wild compared to the captive populations. However, the captive population also showed significantly (P < 0.05) higher levels of some biochemical markers (LDL-c, albumin and albumin/globulin), enzymes (AMS), electrolytes (Cl-) and complete blood count (neutrophil, monocytes and basophil) parameters versus wild populations. Differences in the parameters of captive YFPs could be due to their limited diet of only three fish species as well as their environment (captivity). Whereas, wild YFPs, continuously feed on a large variety of live fish species and shrimp as they travel long distances. Our results suggest that mineral supplements be added to their diet. As well, improved physical fitness training and hygienic conditions are required for the effective management of captive finless porpoises.

Identifying the unmet supportive care needs of men living with and beyond prostate cancer: A systematic review.

PURPOSE: Men affected by prostate cancer are a patient population in need of on-going person-centred supportive care. Our aim was to synthesise current available evidence with regard to the unmet supportive care needs of men living with and beyond prostate cancer. METHODS: A systematic review was conducted according to the PRISMA Statement Guidelines. Electronic databases (DARE, Cochrane MEDLINE, BNI, PsychINFO, EMBASE and CIHAHL) were searched to identify studies employing qualitative and/or quantitative methods. Methodological evaluation was conducted, and findings were integrated in a narrative synthesis. RESULTS: 7521 references were retrieved, 17 articles met the eligibility criteria. Individual needs were classified into the following domains: social needs (2/17: 11.8%), spiritual needs (4/7: 23.5%), practical needs (4/17: 23.5%), daily living needs (5/17: 29.4%), patient-clinician communication (5/17: 29.4%), family-related needs (7/17: 41.2%), physical needs (8/17: 47.1%), psychological emotional needs (9/17: 52.9%), interpersonal/intimacy needs (11/17: 64.7%) and health system/Information needs (13/17: 76.5%). CONCLUSIONS: This systematic review has identified that men can experience a range of unmet supportive care needs with the most frequently reported being needs related to intimacy, informational, physical and psychological needs. Despite the emerging evidence-base, the current with-in study limitations precludes our understanding about how the needs of men evolve over time from diagnosis to living with and beyond prostate cancer. Whether demographic or clinical variables play a moderating role, only remains to be addressed in future studies. This review has made an important contribution by informing clinicians about the complex unmet supportive care needs of men affected by this disease.

A qualitative assessment of human cadavers embalmed by Thiel's method used in laparoscopic training for renal resection.

Human cadaveric tissue is the fundamental substrate for basic anatomic and surgical skills training. A qualitative assessment of the use of human cadavers preserved by Thiel's method for a British Association of Urological Surgeons-approved, advanced laparoscopic renal resection skills training course is described in the present study. Four trainees and four experienced laparoscopic surgeons participated in the course. All participants completed a five-point Likert scale satisfaction questionnaire after their training sessions. The quality of cadaveric tissue and the training session were assessed with particular emphasis placed on the ease of patient positioning, the ease of trocar placement, the preservation of tissue planes, the ease of renal pedicle dissection, and the quality of tissue preservation. All of the participants highly rated the quality of the cadaveric tissue embalmed by Thiel's method (mean scores for quality on the five-point Likert scale were 4.5 and 4.3 by the trainees and experienced laparoscopic surgeons, respectively). All of the steps of laparoscopic renal resection were rated 4.0 or more on the Likert scale by both trainees and faculty members. The initial response rates for using a human cadaver embalmed by Thiel's method as a training tool for laparoscopic nephrectomy showed encouraging results. The performance of a laparoscopic nephrectomy on a human cadaver embalmed by Thiel's method bears close resemblance to real laparoscopic nephrectomy procedures, and thus demonstrates added advantages to the previously reported models.

Surgical treatments for men with benign prostatic enlargement: cost effectiveness study.

OBJECTIVE: To determine which surgical treatment for lower urinary tract symptoms suggestive of benign prostate enlargement is cost effective. DESIGN: Care pathways describing credible treatment strategies were decided by consensus. Cost-utility analysis used Markov modelling and Monte Carlo simulation. DATA SOURCES: Clinical effectiveness data came from a systematic review and an individual level dataset. Utility values came from previous economic evaluations. Costs were calculated from National Health Service (NHS) and commercial sources. METHODS: The Markov model included parameters with associated measures of uncertainty describing health states between which individuals might move at three monthly intervals over 10 years. Successive annual cohorts of 25,000 men were entered into the model and the probability that treatment strategies were cost effective was assessed with Monte Carlo simulation with 10,000 iterations. RESULTS: A treatment strategy of initial diathermy vaporisation of the prostate followed by endoscopic holmium laser enucleation of the prostate in case of failure to benefit or subsequent relapse had an 85% probability of being cost effective at a willingness to pay value of pound20,000 (euro21,595, $28,686)/quality adjusted life year (QALY) gained. Other strategies with diathermy vaporisation as the initial treatment were generally cheaper and more effective than the current standard of transurethral resection repeated once if necessary. The use of potassium titanyl phosphate laser vaporisation incurred higher costs and was less effective than transurethral resection, and strategies involving initial minimally invasive treatment with microwave thermotherapy were not cost effective. Findings were unchanged by wide ranging sensitivity analyses. CONCLUSION: The outcome of this economic model should be interpreted cautiously because of the limitations of the data used. The finding that initial vaporisation followed by holmium laser enucleation for failure or relapse might be advantageous both to men with lower urinary tract symptoms and to healthcare providers requires confirmation in a good quality prospective clinical trial before any change in current practice. Potassium titanyl phosphate laser vaporisation was unlikely to be cost effective in our model, which argues against its unrestricted use until further evidence of effectiveness and cost reduction is obtained.
