Objectives: To assess the resection quality of transurethral bladder tumour resection (TURBT) and the association to surgeon experience depending on the presence of detrusor muscle., Methods: A retrospective study on 640 TURBT procedures performed at Zealand University Hospital, Denmark, from 1 January 2015 - 31 December 2016. Data included patient characteristics, procedure type, surgeon category, supervisor presence, surgical report data, pathological data, complications data and recurrence data. Analysis was performed using simple and multiple logistic regression on the association between surgeon experience and the presence of detrusor muscle in resected tissue from TURBT., Results: Supervised junior residents had significant lower detrusor muscle presence (73%) compared with consultants (83%) (OR = 0.4, 95% CI = 0.21-0.83). Limitations were the retrospective design and the diversity of included TURBT., Conclusions: It was found that surgical experience predicts detrusor muscle presence and supervised junior residents performing TURBT on patients resulted in less detrusor muscle than consultants.

Objective: The purpose of active surveillance (AS) is to reduce overtreatment of men with localized prostate cancer (PCa) without compromising survival. The objective of this study was to update a large Scandinavian single-center AS cohort. Furthermore, the use of curative treatment and subsequent risk of biochemical recurrence were investigated and compared in men with very low-risk, low-risk and intermediate-risk PCa in the cohort., Materials and Methods: In total, 451 men were followed on AS and monitored with prostate-specific antigen (PSA) tests, digital rectal examinations and rebiopsies. Recommendation of curative treatment was based on protocolled and predefined risk of progression criteria. Biochemical recurrence was defined as PSA ≥0.2 ng/ml after radical prostatectomy and PSA nadir +2 ng/ml after radiotherapy., Results: Altogether, 34% were defined with very low-risk PCa, 40% with low-risk PCa and 24% with intermediate-risk PCa. The median follow-up was 5.1 years. The estimated 5 year curatively intended treatment-free survival was 60.5% [95% confidence interval (CI) 54.8-66.2%], with no statistically significant difference between men with very low-risk, low-risk or intermediate-risk PCa. The 5 year biochemical recurrence-free survival was 92.3% (95% CI 87.4-97.2), again with no difference between men with very low-risk, low-risk and intermediate-risk PCa., Conclusion: AS for very low- to low-risk localized PCa is feasible and safe within the short to intermediate time frame. Men with intermediate-risk PCa had the same risk of undergoing curative treatment as men with low-risk PCa, without compromising biochemical recurrence-free survival.
