RESUMO
PURPOSE: Enhanced recovery after surgery (ERAS) protocols have been implemented across a variety of disciplines to improve outcomes. Herein we describe the impact of ERAS on quality of life (QOL) and cost for patients undergoing urologic oncology surgery. METHODS: A systematic literature search using the MEDLINE, Scopus, Clinictrials.gov, and Cochrane Review databases for studies published between 1946 and 2020 was conducted. Articles were reviewed and assigned a risk of bias by two authors and were included if they addressed ERAS and either QOL or cost-effectiveness for patients undergoing urologic oncology surgery. RESULTS: The literature search yielded a total of 682 studies after removing duplicates, of which 10 (1.5%) were included in the review. Nine articles addressed radical cystectomy, while one addressed ERAS and QOL for laparoscopic nephrectomy. Six publications assessed the impact of ERAS on QOL domains. Questionnaires used for assessment of QOL varied across studies, and timing of administration was heterogeneous. Overall, ERAS improved patient QOL during early phases of recovery within the realms of bowel function, physical/social/cognitive functioning, sleep and pain control. Costs were assessed in 4 retrospective studies including 3 conducted in the United States and one from China all addressing radical cystectomy. Studies demonstrated either decreased costs associated with ERAS as a result of decreased length of stay or no change in cost based on ERAS implementation. CONCLUSION: While limited studies are published on the subject, ERAS implementation for radical cystectomy and laparoscopic nephrectomy improved patient-reported QOL during early phases of recovery. For radical cystectomy, there was a decreased or neutral overall financial cost associated with ERAS. Further studies assessing QOL and cost-effectiveness over the entire global period of care in a variety of urologic oncology surgeries are warranted.

BACKGROUND: Lower urinary tract symptoms (LUTS) in men may indicate bladder outlet obstruction (BOO) or weakness, known as detrusor underactivity (DU). Severe bothersome LUTS are a common indication for surgery. The diagnostic tests may include urodynamics (UDS) to confirm whether BOO or DU is the cause, potentially reducing the number of people receiving (inappropriate) surgery. OBJECTIVES: The primary objective was to determine whether a care pathway including UDS is no worse for symptom outcome than one in which it is omitted, at 18 months after randomisation. Rates of surgery was the key secondary outcome. DESIGN: This was a pragmatic, multicentre, two-arm (unblinded) randomised controlled trial, incorporating a health economic analysis and qualitative research. SETTING: Urology departments of 26 NHS hospitals in England. PARTICIPANTS: Men (aged ≥ 18 years) seeking further treatment, potentially including surgery, for bothersome LUTS. Exclusion criteria were as follows: unable to pass urine without a catheter, having a relevant neurological disease, currently undergoing treatment for prostate or bladder cancer, previously had prostate surgery, not medically fit for surgery and/or unwilling to be randomised. INTERVENTIONS: Men were randomised to a care pathway based on non-invasive routine tests (control) or routine care plus invasive UDS (intervention arm). MAIN OUTCOME MEASURES: The primary outcome was International Prostate Symptom Score (IPSS) at 18 months after randomisation and the key secondary outcome was rates of surgery. Additional secondary outcomes included adverse events (AEs), quality of life, urinary and sexual symptoms, UDS satisfaction, maximum urinary flow rate and cost-effectiveness. RESULTS: A total of 820 men were randomised (UDS, 427; routine care, 393). Sixty-seven men withdrew before 18 months and 11 died (unrelated to trial procedures). UDS was non-inferior to routine care for IPSS 18 months after randomisation, with a confidence interval (CI) within the margin of 1 point (-0.33, 95% CI -1.47 to 0.80). A lower surgery rate in the UDS arm was not found (38% and 36% for UDS and routine care, respectively), with overall rates lower than expected. AEs were similar between the arms at 43-44%. There were more cases of acute urinary retention in the routine care arm. Patient-reported outcomes for LUTS improved in both arms and satisfaction with UDS was high in men who received it. UDS was more expensive than routine care. From a secondary care perspective, UDS cost an additional £216 over an 18-month time horizon. Quality-adjusted life-years (QALYs) were similar, with a QALY difference of 0.006 in favour of UDS over 18 months. It was established that UDS was acceptable to patients, and valued by both patients and clinicians for its perceived additional insight into the cause and probable best treatment of LUTS. LIMITATIONS: The trial met its predefined recruitment target, but surgery rates were lower than anticipated. CONCLUSIONS: Inclusion of UDS in the diagnostic tests results in a symptom outcome that is non-inferior to a routine care pathway, but does not affect surgical rates for treating BOO. Results do not support the routine use of UDS in men undergoing investigation of LUTS. FUTURE WORK: Focus should be placed on indications for selective utilisation of UDS in individual cases and long-term outcomes of diagnosis and therapy. TRIAL REGISTRATION: Current Controlled Trials ISRCTN56164274.

After hospital referral, men with bothersome lower urinary tract symptoms (LUTS) are assessed with standard tests. These include measurement of urine flow rate, bladder diaries and questionnaires, including the International Prostate Symptom Score (IPSS). UPSTREAM (Urodynamics for Prostate Surgery Trial; Randomised Evaluation of Assessment Methods) researched whether or not including an extra test, urodynamics (UDS), helps when considering treatment options. UDS is a more invasive test and measures pressure in the bladder to check whether or not the prostate is causing obstruction. It was presumed that, if there is no obstruction, surgery would not be offered, so that using UDS would reduce the number of prostate operations. Each man participating (820 in total) was assessed with the standard tests. Around half of them had no extra tests (the 'routine care' arm of the trial); the rest had the UDS tests (the 'UDS' arm). Men then went on to have treatment, which they chose having discussed their test results with a urologist. IPSS and other symptom scores were examined for each man 18 months after joining the trial. At 18 months, surgery outcomes were known for 792 men and IPSS was known for 669 men. We investigated if the two trial arms showed similar changes in the IPSS and if there were fewer operations done in the UDS arm. We identified similar reductions in the IPSS in both arms. However, UDS tests did not reduce the number of operations. Analysing all the costs, it was found that a pathway including UDS costs more than routine care. Interviews were conducted that showed that men found UDS acceptable, and that the additional information helped both the men and their doctors consider which treatment would be most appropriate. These results do not support the routine use of UDS in the assessment of every man considering prostate surgery for LUTS. Further exploration of the data may identify circumstances in which UDS could be helpful.

BACKGROUND: Prostate surgery can improve lower urinary tract symptoms (LUTS) by relieving bladder outlet obstruction (BOO). However, surgery is less effective without BOO, or if detrusor underactivity is present. Urodynamics (UDS) can identify BOO and measure detrusor activity, but evidence in clinical practice is lacking. OBJECTIVE: Urodynamics for Prostate Surgery Trial: Randomised Evaluation of Assessment Methods (UPSTREAM) aimed to evaluate whether a care pathway including UDS would reduce surgery without increasing urinary symptoms. DESIGN, SETTING, AND PARTICIPANTS: UPSTREAM is a pragmatic, noninferiority, randomised controlled trial in men with bothersome LUTS, in whom surgery was an option, in 26 hospitals in England (ISRCTN56164274). INTERVENTION: Participants were randomised (1:1) to routine care (RC) diagnostic tests, or RC plus UDS. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was the International Prostate Symptom Score (IPSS; patient-reported outcome scale from 0 to 35 points) 18 mo after randomisation, with a noninferiority margin of 1 point. Urological surgery rates were a key secondary outcome. The primary outcome was compared between the arms using linear regression, analysed on an intention-to-treat basis. RESULTS AND LIMITATIONS: Between October 2014 and December 2016, 820 men (median age 68 yr) were randomised (393 and 427 in the RC and UDS arms, respectively). The UDS arm showed noninferiority of the mean IPSSs (UDS 12.6; RC 13.1; adjusted difference at 18 mo -0.33 [95% confidence interval {CI} -1.47, +0.80]). In the UDS arm, 153/408 (38%) received surgery compared with 138/384 (36%) in the RC arm (adjusted odds ratio 1.05; 95% CI 0.77, 1.43). A total of 428 adverse events (UDS 234; RC 194) were recorded, with related events similar in both arms and 11 unrelated deaths. CONCLUSIONS: In this population, the UDS randomised group was noninferior to RC for the IPSS but did not reduce surgical rates. This study shows that routine use of UDS in the evaluation of uncomplicated LUTS has a limited role and should be used selectively. PATIENT SUMMARY: For men with uncomplicated lower urinary tract symptoms, symptom improvements after treatment and the number of operations performed are similar, irrespective of whether or not urodynamic tests are conducted in addition to routine tests. Accordingly, routine use of urodynamics has a limited role in this population group.

BACKGROUND: Clinical evaluation of male lower urinary tract symptoms (MLUTS) in secondary care uses a range of assessments. It is unknown how MLUTS evaluation influences outcome of therapy recommendations and choice, notably urodynamics (UDS; filling cystometry and pressure flow studies). OBJECTIVE: To report participants' sociodemographic and clinical characteristics, and initial diagnostic findings of the Urodynamics for Prostate Surgery Trial; Randomised Evaluation of Assessment Methods (UPSTREAM). UPSTREAM is a randomised controlled trial evaluating whether symptoms are noninferior and surgery rates are lower if UDS is included. DESIGN, SETTING, AND PARTICIPANTS: A total of 820 men (≥18 yr of age) seeking treatment for bothersome LUTS were recruited from 26 National Health Service hospital urology departments. INTERVENTION: Care pathway based on routine, noninvasive tests (control) or routine care plus UDS (intervention arm). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome is International Prostate Symptom Score (IPSS) and the key secondary outcome is surgery rates 18 mo after randomisation. International Consultation on Incontinence Questionnaires were captured for MLUTS, sexual function, and UDS satisfaction. Baseline clinical and patient-reported outcome measures (PROMs), and UDS findings were informally compared between arms. Trends across age groups for urinary and sexual PROMs were evaluated with a Cuzick's test, and questionnaire items were compared using Pearson's correlation coefficient. RESULTS AND LIMITATIONS: Storage LUTS, notably nocturia, and impaired sexual function are prominent in men being assessed for surgery. Sociodemographic and clinical evaluations were similar between arms. Overall mean IPSS and quality of life scores were 18.94 and 4.13, respectively. Trends were found across age groups, with older men suffering from higher rates of incontinence, nocturia, and erectile dysfunction, and younger men suffering from increased daytime frequency and voiding symptoms. Men undergoing UDS testing expressed high satisfaction with the procedure. CONCLUSIONS: Men being considered for surgery have additional clinical features that may affect treatment decision making and outcomes, notably storage LUTS and impaired sexual function. PATIENT SUMMARY: We describe initial assessment findings from a large clinical study of the treatment pathway for men suffering with bothersome urinary symptoms who were referred to hospital for further treatment, potentially including surgery. We report the patient characteristics and diagnostic test results, including symptom questionnaires, bladder diaries, flow rate tests, and urodynamics.

OBJECTIVES: To describe contemporary radical prostatectomy (RP) practice using the British Association of Urological Surgeons (BAUS) data and audit project and to observe differences in practice in relation to surgeon or centre case-volume. PATIENTS AND METHODS: Data on 13 920 RP procedures performed by 179 surgeons across 86 centres were recorded on the BAUS data and audit platform between 1 January 2014 and 31 December 2015. This equates to ~95% of total RPs performed over this period when compared to Hospital Episode Statistics (HES) data. Centre case-volumes were categorised as 'high' (>200), 'medium' (100-200) and 'low' (<100); surgeon case-volumes were categorised as 'high' (>100) and 'low' (<100). Differences in surgical practice and selected outcome measures were observed between groups. All data and volume categories were for the combined 2-year period. RESULTS: The median number of RPs performed over the 2-year period was 63.5 per surgeon and 164 per centre. Overall, surgical approach was robot-assisted laparoscopic RP (RALP) in 65%, laparoscopic RP (LRP) in 23%, and open RP (ORP) in 12%. The dominant approach in high-case-volume centres and by high-case-volume surgeons was RALP (74.3% and 69.2%, respectively). There was a greater percentage of ORPs reported by low-volume surgeons and centres when compared to higher volume equivalents. In all, 51.6% of all patients in this series underwent RP in high-case-volume centres using robot-assisted surgery (RAS). High-case-volume surgeons performed nerve-sparing (NS) procedures on 57.3% of their cases; low-volume surgeons performing NS on 48.2%. Overall, lymph node dissection (LND) rates were very similar across the groups. An 'extended' LND was more commonly performed in high-volume centres (22.1%). The median length of stay (LOS) was lowest in patients undergoing RALP at high-volume centres (1 day) and highest in ORP across all volume categories (3-4 days). Reported pT2 positive surgical margin (PSM) rate varied by technique, centre volume, and surgeon volume. In general, observed PSM rates were lower when RALP was the surgical approach (14.4%) and when high-volume surgeons were compared to low-volume surgeons (13.6% vs 17.7%). Transfusion rates were highest in ORP across all centres and surgeons (2.96-4.49%) compared to techniques using a minimally-invasive approach (0.25-2.41%). Training cases ranged from 0.5% in low-volume centres to 6.0% in high-volume centres. CONCLUSIONS: Compliance with data registration for centres and surgeons performing RP is high in the present series. Most RPs were performed in high-case-volume centres and by high-case-volume surgeons, with the most common approaches being minimally invasive and specifically RAS. High-case-volume centres and surgeons reported higher rates of extended LND and training cases. Higher-case-volume surgeons reported lower pT2 PSM rates, whilst the most marked differences in transfusion rates and LOS were seen when ORP was compared to minimally invasive approaches. Caution must be applied when interpreting these differences on the basis of this being registry data - causality cannot be assumed.

Many modern filtration technologies are incapable of the complete removal of Cryptosporidium oocysts from drinking-water. Consequently, Cryptosporidium-contaminated drinking-water supplies can severely implicate both water utilities and consumers. Existing methods for the detection of Cryptosporidium in drinking-water do not discern between non-pathogenic and pathogenic species, nor between viable and non-viable oocysts. Using FluidFM, a novel force spectroscopy method employing microchannelled cantilevers for single-cell level manipulation, we assessed the size and deformability properties of two species of Cryptosporidium that pose varying levels of risk to human health. A comparison of such characteristics demonstrated the ability of FluidFM to discern between Cryptosporidium muris and Cryptosporidium parvum with 86% efficiency, whilst using a measurement throughput which exceeded 50 discrete oocysts per hour. In addition, we measured the deformability properties for untreated and temperature-inactivated oocysts of the highly infective, human pathogenic C. parvum to assess whether deformability may be a marker of viability. Our results indicate that untreated and temperature-inactivated C. parvum oocysts had overlapping but significantly different deformability distributions.

The ability to work under pressure is a vital non-technical skill for doctors working in acute medical specialties. Individuals who evaluate potentially stressful situations as challenging rather than threatening may perform better under pressure and be more resilient to stress and burnout. Training programme recruitment processes provide an important opportunity to examine applicants' reactions to acute stress. In the context of multi-station selection centres for recruitment to anaesthesia training programmes, we investigated the factors influencing candidates' pre-station challenge/threat evaluations and the extent to which their evaluations predicted subsequent station performance. Candidates evaluated the perceived stress of upcoming stations using a measure of challenge/threat evaluation-the cognitive appraisal ratio (CAR)-and consented to release their demographic details and station scores. Using regression analyses we determined which candidate and station factors predicted variation in the CAR and whether, after accounting for these factors, the CAR predicted candidate performance in the station. The CAR was affected by the nature of the station and candidate gender, but not age, ethnicity, country of training or clinical experience. Candidates perceived stations involving work related tasks as more threatening. After controlling for candidates' demographic and professional profiles, the CAR significantly predicted station performance: 'challenge' evaluations were associated with better performance, though the effect was weak. Our selection centre model can help recruit prospective anaesthetists who are able to rise to the challenge of performing in stressful situations but results do not support the direct use of challenge/threat data for recruitment decisions.

BACKGROUND: The efficacy of neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (BCa) was established primarily with methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC), with complete response rates (pT0) as high as 38%. However, because of the comparable efficacy with better tolerability of gemcitabine and cisplatin (GC) in patients with metastatic disease, GC has become the most commonly used regimen in the neoadjuvant setting. OBJECTIVE: We aimed to assess real-world pathologic response rates to NAC with different regimens in a large, multicenter cohort. DESIGN, SETTING, AND PARTICIPANTS: Data were collected retrospectively at 19 centers on patients with clinical cT2-4aN0M0 urothelial carcinoma of the bladder who received at least three cycles of NAC, followed by radical cystectomy (RC), between 2000 and 2013. INTERVENTION: NAC and RC. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was pathologic stage at cystectomy. Univariable and multivariable analyses were used to determine factors predictive of pT0N0 and ≤pT1N0 stages. RESULTS AND LIMITATIONS: Data were collected on 935 patients who met inclusion criteria. GC was used in the majority of the patients (n=602; 64.4%), followed by MVAC (n=183; 19.6%) and other regimens (n=144; 15.4%). The rates of pT0N0 and ≤pT1N0 pathologic response were 22.7% and 40.8%, respectively. The rate of pT0N0 disease for patients receiving GC was 23.9%, compared with 24.5% for MVAC (p=0.2). There was no difference between MVAC and GC in pT0N0 on multivariable analysis (odds ratio: 0.89 [95% confidence interval, 0.61-1.34]; p=0.6). CONCLUSIONS: Response rates to NAC were lower than those reported in prospective randomized trials, and we did not discern a difference between MVAC and GC. Without any evidence from randomized prospective trials, the best NAC regimen for invasive BCa remains to be determined. PATIENT SUMMARY: There was no apparent difference in the response rates to the two most common presurgical chemotherapy regimens for patients with bladder cancer.

BACKGROUND: Previous research has demonstrated that trainees can be taught (via explicit verbal instruction) to adopt the gaze strategies of expert laparoscopic surgeons. The current study examined a software template designed to guide trainees to adopt expert gaze control strategies passively, without being provided with explicit instructions. METHODS: We examined 27 novices (who had no laparoscopic training) performing 50 learning trials of a laparoscopic training task in either a discovery-learning (DL) group or a gaze-training (GT) group while wearing an eye tracker to assess gaze control. The GT group performed trials using a surgery-training template (STT); software that is designed to guide expert-like gaze strategies by highlighting the key locations on the monitor screen. The DL group had a normal, unrestricted view of the scene on the monitor screen. Both groups then took part in a nondelayed retention test (to assess learning) and a stress test (under social evaluative threat) with a normal view of the scene. RESULTS: The STT was successful in guiding the GT group to adopt an expert-like gaze strategy (displaying more target-locking fixations). Adopting expert gaze strategies led to an improvement in performance for the GT group, which outperformed the DL group in both retention and stress tests (faster completion time and fewer errors). CONCLUSION: The STT is a practical and cost-effective training interface that automatically promotes an optimal gaze strategy. Trainees who are trained to adopt the efficient target-locking gaze strategy of experts gain a performance advantage over trainees left to discover their own strategies for task completion.
