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.
The objective was to assess the clinical effectiveness and cost-effectiveness of photodynamic diagnosis-guided transurethral resection of bladder tumour.
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.
The setting was 22 NHS hospitals.
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.
Photodynamic diagnosis-guided transurethral resection of bladder tumour and standard white-light cystoscopy transurethral resection of bladder tumour.
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.
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 (
= 5), lack of non-muscle-invasive bladder cancer diagnosis following transurethral resection of bladder tumour (
= 89) or early cystectomy (
= 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;
= 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.
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.
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.
Further work should include the modelling of appropriate surveillance schedules and exploring predictive and prognostic biomarkers.

Urology, traditionally a maledominated specialty, keeping pace with the quickly changing gender landscape, has been characterized by waves of feminization. This study aims to understand the ...perspectives of women urologists on the obstacles to their career development, and the impact of such hurdles on their professional roles in urological education, practice, and leadership.
119 female urology residents/consultants were surveyed via a webinar-based platform, covering relevant questions on domains of Academia, Mentorship, Leadership, Parenting, and Charity. Statistical analysis was done using frequency distribution based on the responses.
46.8% of the respondents felt that there is an under-representation of women in academia. 'Having a good mentor' was the most important factor for a novice to succeed in academia (68%). The most important trait in becoming a good leader was 'good communication skills' (35%), followed by 'visionary' (20%). The greatest challenge faced by leaders in the medical field was considered as 'time management' (31.9%). Only 21.2% of the participants felt difficulty in having a work-personal life balance, whereas 63.8% of them found it difficult only 'sometimes'. As a working parent, 'the guilt that they are not available all the time' was considered the most difficult aspect (59.5%), and 'more flexible schedule' was needed to make their lives as a working parent easier (46.8%). 34% of the respondents were affiliated with some charitable organizations. The biggest drive to do charity was their satisfaction with a noble cause (72.3%).
Need for increased encouragement and recruitment of females into urology, and to support and nurture them in their career aspirations.
Correction After publication of this supplement 1, it was brought to our attention that two authors were missing for abstract P66: Recruitment aids for a phase II randomised trial in low risk bladder ...cancer. The two missing authors can be found in this Erratum.
Objectives To evaluate the effect of previous transurethral resection of the prostate (TURP) on surgical, functional, and oncologic outcomes after laparoscopic radical prostatectomy. Methods From a ...series of 2100 patients undergoing laparoscopic radical prostatectomy, we compared the intraoperative complications and functional and oncologic outcomes for 55 patients who had been diagnosed with prostate carcinoma on previous TURP (group 1), with those of 55 matched patients who had not undergone previous prostate surgery (group 2). The patients were match-paired for age, operating surgeon, procedure type (eg, nerve-sparing, lymph node dissection), anastamotic technique, pathologic stage, and Gleason score. The minimal duration of follow-up was 24 months. Results Both groups were similar with respect to patient age and pathologic stage. Of those with Stage cT1a and cT1b, 83.6% had a clinically significant tumor, with a mean tumor volume of 1.7 cm3 for those with Stage cT1a and 2.4 cm3 for those with Stage cT1b. The positive surgical margin rate was 14.5% and 16.3% for groups 1 and 2, respectively. Biochemical recurrence developed in 12.7% and 11% of patients in groups 1 and 2, respectively. Neither outcome was significantly different between the 2 groups. The long-term continence rates were similar; however, previous TURP was associated with a lower continence rate (49.1%) at 3 months compared with 61.8% for group 2 ( P = .01). A nerve-sparing technique was used in 54% of group 1 patients. No significant difference was found in the potency rates between the 2 groups at 12 months. Conclusions Laparoscopic radical prostatectomy after TURP is a challenging, but oncologically safe, procedure. The interval to total continence was delayed, but the potency rates remain unchanged.
BACKGROUNDThe main objective of this study was to evaluate the various instruments available to evaluate the quality of life (QoL) in patients diagnosed with non-muscle invasive bladder cancer ...(NMIBC) undergoing surveillance. METHODSA PubMed literature review was carried out with query terms ("Urinary Bladder Neoplasms" Mesh OR "Bladder malignancy") AND ("quality of life") including all studies up to June 2020. This resulted in 576 peer-reviewed articles. A further 12 articles from additional sources were included. A total of 473 articles were eliminated due to lack of relevance to the topic of concern. A further 93 articles evaluating NMIBC and articles evaluating Radiotherapy were excluded and a total of 22 studies were studied. RESULTSIn total, 22 studies were identified. The vast majority of studies were prospective descriptive studies (n=9), while there were 7 cross-sectional surveys and 6 randomised controlled trials. Most studies evaluated the impact of intravesical treatment on QoL. NMIBC survivors had significantly lower QoL compared to the general population, Surveillance strategies involving repeated intravesical therapies and cystoscopies have a negative impact on QoL with impaired physical function and mental health. CONCLUSIONSThis article emphasizes the importance of assessing the QoL in patients with NMIBC undergoing long term surveillance, as they represent the majority of bladder cancer patients. Development and validation of specific instruments to measure QoL in patients with NMIBC are desperately needed to assess, better understand, and manage the burden of disease and healthcare in this group of patients.
Computerized tomography urogram is recommended when investigating patients with hematuria. We determined the incidence of urinary tract cancer and compared the diagnostic accuracy of computerized ...tomography urogram to that of renal and bladder ultrasound for identifying urinary tract cancer.
The DETECT (Detecting Bladder Cancer Using the UroMark Test) I study is a prospective observational study recruiting patients 18 years old or older following presentation with macroscopic or microscopic hematuria at a total of 40 hospitals. All patients underwent cystoscopy and upper tract imaging comprising computerized tomography urogram and/or renal and bladder ultrasound.
A total of 3,556 patients with a median age of 68 years were recruited in this study, of whom 2,166 underwent renal and bladder ultrasound, and 1,692 underwent computerized tomography urogram in addition to cystoscopy. The incidence of bladder, renal and upper tract urothelial cancer was 11.0%, 1.4% and 0.8%, respectively, in macroscopic hematuria cases. Patients with microscopic hematuria had a 2.7%, 0.4% and 0% incidence of bladder, renal and upper tract urothelial cancer, respectively. The sensitivity and negative predictive value of renal and bladder ultrasound to detect renal cancer were 85.7% and 99.9% but they were 14.3% and 99.7%, respectively, to detect upper tract urothelial cancer. Renal and bladder ultrasound was poor at identifying renal calculi. Renal and bladder ultrasound sensitivity was lower than that of computerized tomography urogram to detect bladder cancer (each less than 85%). Cystoscopy had 98.3% specificity and 83.9% positive predictive value.
Computerized tomography urogram can be safely replaced by renal and bladder ultrasound in patients who have microscopic hematuria. The incidence of upper tract urothelial cancer is 0.8% in patients with macroscopic hematuria and computerized tomography urogram is recommended. Patients with suspected renal calculi require noncontrast renal tract computerized tomography. Imaging cannot replace cystoscopy to diagnose bladder cancer.
There remains a lack of consensus among guideline relating to which patients require investigation for haematuria. We determined the incidence of urinary tract cancer in a prospective observational ...study of 3556 patients referred for investigation of haematuria across 40 hospitals between March 2016 and June 2017 (DETECT 1; ClinicalTrials.gov: NCT02676180) and the appropriateness of age at presentation in cases with visible (VH) and nonvisible (NVH) haematuria. The overall incidence of urinary tract cancer was 10.0% (bladder cancer 8.0%, renal parenchymal cancer 1.0%, upper tract transitional cell carcinoma 0.7%, and prostate cancer 0.3%). Patients with VH were more likely to have a diagnosis of urinary tract cancer compared with NVH patients (13.8% vs 3.1%). Older patients, male gender, and smoking history were independently associated with urinary tract cancer diagnosis. Of bladder cancers diagnosed following NVH, 59.4% were high-risk cancers, with 31.3% being muscle invasive. The incidence of cancer in VH patients <45 yr of age was 3.5% (n=7) and 1.0% (n=4) in NVH patients <60 yr old. Our results suggest that patients with VH should be investigated regardless of age. Although the risk of urinary tract cancer in NVH patients is low, clinically significant cancers are detected below the age threshold for referral for investigation.
This study highlights the requirement to investigate all patients with visible blood in the urine and an age threshold of ≥60 yr, as recommended in some guidelines, as the investigation of nonvisible blood in the urine will miss a significant number of urinary tract cancers. Patient preference is important, and evidence that patients are willing to submit to investigation should be considered in reaching a consensus recommendation for the investigation of haematuria. International consensus to guide that patients will benefit from investigation should be developed.
Visible haematuria should be investigated regardless of age. While the risk of urinary tract cancer in patients with NVH, aged <60 yr, is low, clinically significant bladder cancers are still diagnosed. A Europe-wide consensus for haematuria should be developed.
