What actually happens during a radical prostatectomy? 🍆
If you’re preparing for prostate cancer surgery, understanding the anatomy can make what happens afterwards make a lot more sense.
During a radical prostatectomy, the entire prostate gland is removed, usually along with the seminal vesicles.
But the prostate doesn’t sit in isolation.
It sits directly beneath the bladder, with the urethra running through it. So when the prostate is removed:
👉 The urethra is divided.
👉 The prostate is removed.
👉 The bladder neck is then reconnected to the remaining urethra — called a vesicourethral anastomosis.
👉 A catheter is temporarily left in place while this new connection heals.
And then there are the nerves.
The neurovascular bundles responsible for erectile function run extremely close to the prostate. Where it is oncologically safe, surgeons may perform nerve-sparing surgery — preserving one or both bundles.
But even when the nerves are preserved, they can be stretched, bruised or temporarily affected by surgery.
This helps explain why two of the biggest challenges after prostatectomy can be:
💧 Urinary incontinence
🍆 Changes in erectile function
It’s also why rehabilitation isn’t an optional afterthought.
Understanding what has physically changed allows us to rehabilitate the pelvic floor, bladder function, erections, strength and confidence progressively after surgery.
Next, we’ll look at what to expect in those first few days with the catheter in place.
