Urethral recurrence after radical cystoprostatectomy: Experience from a high-volume tertiary referral centre

Abstract

Objectives: To report our urethral surveillance programme and urethral cancer recurrence rate following radical cystoprostatectomy (RC). Patients and methods: A retrospective analysis of clinical and histopathological data of men who underwent RC and urethral surveillance, between January 2011 and October 2016. Results: RC was performed for 491 men; 31 and 19 men had a synchronous (malignancy, n = 10, 32.3%) and interval (malignancy, n = 6, 31.6%) urethrectomy, respectively. The remaining 441 men underwent surveillance; 183 (41.5%) men had at least one urethroscopy, 14 (3.2%) urethrectomies were performed and 12 (2.7%) specimens confirmed urethral recurrence (UR). Within the URs, 7/12 (58.3%) men presented symptomatically and 5/12 (41.7%) were detected through surveillance. At a median (interquartile range) follow-up of 21.8 (9.7–36.7) months, the 2-year disease-specific survival in men who had synchronous urethrectomy was 71.4% (versus no urethrectomy (84.6%) interval urethrectomy (92.9%) and urethrectomy for recurrence (83.8%)). Conclusion: UR following RC is low in men without risk factors for urethral disease. Annual urethroscopy and urine cytology may not be feasible and appropriate in all men after RC, and does not appear to impact survival at 2 years. A risk-adapted approach may allow the avoidance of annual urethroscopy in asymptomatic men post RC. Level of Evidence: 3b
