Kegels After Prostatectomy: What the Science Recommends

After a radical prostatectomy, two questions dominate the conversation in the doctor's office: when urinary control comes back, and whether erections come back. Almost every urologist mentions pelvic floor exercises at discharge, sometimes with a printed handout, sometimes as a single sentence buried in a list of other instructions. What usually goes unsaid is the rest: what exactly to do, when to start, and what to expect.

This article gathers what clinical trials show about pelvic floor training after prostate surgery. Where the evidence is solid, where it is split, and where it is still thin. The numbers come from four randomized studies published in urology journals. It is the same foundation behind the training in Ritmo, with one caveat worth stating up front: anyone who has had surgery trains with medical clearance and follow-up, not on their own.

Direct answer: what the science recommends

Why the pelvic floor becomes the main structure in charge

Male continence rests on two mechanisms. The first is the internal sphincter, involuntary, located at the bladder neck and anatomically tied to the prostate. The second is the external sphincter, or rhabdosphincter, which you control on purpose and which works together with the pelvic floor muscles.

Radical prostatectomy removes the prostate and, with it, much of the first mechanism. What is left to hold urine is precisely the second one, the voluntary one, the same one Kegels train. It is no coincidence that the exercise appears in practically every recovery protocol: it acts on exactly the structure that was left alone with the job.

With erections, the logic is different and more limited. The neurovascular bundles that drive erection run right alongside the prostate and can be affected during surgery, even with nerve-sparing technique. The ischiocavernosus and bulbocavernosus muscles raise the pressure inside the corpora cavernosa when they contract, which helps maintain firmness, but no muscle replaces a damaged nerve. That is why the gain in erectile function shows up in studies with smaller numbers and less consistency than the gain in continence.

The strongest evidence is about continence

The most cited trial in this area followed 300 men who had undergone radical retropubic prostatectomy, split into two groups of 150. One received structured guidance on pelvic floor exercises right after the catheter came out, before discharge. The other received only the generic verbal instruction to contract the muscles.

Two things about that design deserve attention. The first is "early": the training began as soon as the catheter came out, not months later, once the man had already gotten used to living with the leakage. The second is "guided". Both groups heard about Kegels. Only one learned to do them with supervision, correction and a plan. What the study measured is the difference between knowing the exercise exists and knowing how to perform it.

Training before surgery: this is where the studies disagree

The idea makes sense at first glance: learn to contract the muscle while everything still works, so you arrive at surgery with the skill ready. Two randomized trials tested this and reached different conclusions.

Three years later, a Belgian group ran the test with almost twice as many participants and did not find the same effect.

How do you read two opposite answers without simply picking the one you like? Look at what both studies have in common: in both, everyone trained after surgery, and in both, the preoperative group learned the technique beforehand. What the Belgian study suggests is that the benefit of the preoperative period lies more in the learning than in any extra strength banked ahead of time. Training beforehand is unlikely to hurt, and arriving at surgery already able to find and contract the right muscle removes a step that is hard to complete while wearing a pad and sore from the operation.

What about erections after prostatectomy?

Here the evidence is thinner, but it is not zero. A Brazilian trial randomized 52 men who had had surgery into two groups: one did pelvic floor training with biofeedback right after the procedure, the other did not. Potency was measured with the IIEF-5, the standard erectile function questionnaire, over twelve months of follow-up.

It is worth saying what the study does not say. It does not show that Kegels restore erections in men whose nerves were damaged, and it does not replace the penile rehabilitation a urologist prescribes, medication included. What it indicates is that training the muscles improves the part of the mechanism that depends on muscle. The full reasoning behind that vascular piece is in erectile dysfunction and exercise.

What this means in practice

Putting the four studies together, a few points repeat and work as general guidance, always subordinate to whatever your doctor decides.

1. Wait for the catheter to come out and for your team to clear you. Contracting the muscles with the catheter in place is not part of any of the protocols cited here.
2. Start early after that. The gain in these studies is in the speed of recovery, and speed is exactly what you lose when training starts months later.
3. Make sure you are contracting the right muscle. Glutes, abs and thighs join in easily and give a false sense of effort. How to check this is in how to know if you are contracting the right muscle.
4. Do not use the urine stream as an exercise. Stopping the stream works at most as a one-off identification test and, repeated, interferes with emptying the bladder.
5. Release completely between one contraction and the next. A muscle that stays permanently tense is not a strong muscle, and the release is part of the repetition.
6. Think in months, not days. In these studies, the gap between groups kept widening at three and six months. What changes at each stage is covered in how long it takes to see results with pelvic exercises.

How Ritmo applies this in practice

First, the honest note: Ritmo is guided pelvic floor training for men, not a post-surgical rehabilitation protocol. Anyone who has had a prostatectomy should treat the app as an execution tool inside a plan approved by their urologist or pelvic floor physiotherapist, never as a substitute for that follow-up.

That said, what the app handles is the part the studies point to as decisive: guided execution. Each session is a list of 4 to 7 exercises in sequence, with a rest screen between them, and runs 5 to 10 minutes. During the exercise, the screen shows the timer and the phase label, contract, hold, release or rest, with synchronized vibration. You follow the rhythm without counting anything and without guessing when to let go.

The program alternates two session types of equal weight. Session A trains strength and endurance, with longer holds. Session B trains control and coordination, with quick contractions and staged guided releases. The last exercise of every session is always a progressive release. Progression is automatic, week by week, and rest days are already in the plan. The app icon is discreet and the session can be done wherever you want, with no equipment.

Frequently asked questions

Conclusion

For continence after radical prostatectomy, the science gives a clear answer: pelvic floor training that starts right after the catheter comes out, with real guidance, shortens the time until control returns. At six months, in the Filocamo study, that separated 94.6% from 65% of men who were continent. For erections, the signal is favorable but comes from a small sample, and the training adds to what the urologist prescribes rather than replacing it.

What the studies do not measure is the hardest part: keeping the practice up for months, alone, during a period when almost nothing feels worth doing. That is where having the session ready on screen, with the time counted and the phase shown, matters more than it sounds. Ritmo handles that daily execution, and your doctor handles the plan.
