Abstract

Objectives

To consider the provision of post‐radical prostatectomy (RP) continence surgery in England.

Materials and Methods

Patients with an Office of Population Census and Surveys Classification of Interventions and Procedures, version 4 code for an artificial urinary sphincter (AUS) or male sling between 1 January 2010 and 31 March 2018 were searched for within the Hospital Episode Statistics (HES) dataset. Those without previous RP were excluded. Multivariable logistic regressions for repeat AUS and sling procedures were built in stata. Further descriptive analysis of provision of procedures was performed.

Results

A total of 1414 patients had received index AUS, 10.3% of whom had undergone prior radiotherapy; their median follow‐up was 3.55 years. The sling cohort contained 816 patients; 6.7% of these had received prior radiotherapy and the median follow‐up was 3.23 years. Whilst the number of AUS devices implanted had increased each year, male slings peaked in 2014/2015. AUS redo/removal was performed in 11.2% of patients. Patients in low‐volume centres were more likely to require redo/removal (odds ratio [OR] 2.23 95% confidence interval [CI] 1.02–4.86; P = 0.045). A total of 12.0% patients with a sling progressed to AUS implantation and 1.3% had a second sling. Patients with previous radiotherapy were more likely to require a second operation (OR 2.03 95% CI 1.01–4.06; P = 0.046). Emergency re‐admissions within 30 days of index operation were 3.9% and 3.6% fewer in high‐volume centres, for AUS and slings respectively. The median time to initial continence surgery from RP was 2.8 years. Increased time from RP conferred no reduced risk of redo surgery for either procedure.

Conclusion

There is a volume effect for outcomes of AUS procedures, suggesting that they should only be performed in high‐volume centres. Given the known impact of incontinence on quality of life, patients should be referred sooner for post‐prostatectomy continence surgery.
