## TL;DR

An implanted cuff and pump that keeps the urethra closed until you squeeze the pump to pass urine.

## Summary

NICE NG131 says to refer people with prostate cancer who have intractable stress incontinence to a specialist surgeon for consideration of one. Prostate Cancer UK says it is usually suitable for men still leaking a lot at least six months after treatment, that previous radiotherapy raises the risk of infection or device failure, and that some men need a further operation. An internal male sling is the lighter alternative for men leaking two to three pads a day a year after treatment.
