Kegel Exercises After Prostate Surgery Called Into Question

Kegel exercise

How can Kegel exercise help after prostate surgery?

You may have learned that “Kegel exercise strengthens the group of muscles called the pelvic floor muscles (also known as PC muscles which stand for pubococcygeus.) These muscles contract and relax around the bladder and the bladder opening at your command. When these muscles are weak, urine leakage may result. You can exercise these muscles just like any other muscle in your body and building them up may help reduce your symptoms. It is important that you perform these exercises correctly and consistently to gain maximum benefit after prostate cancer surgery.”1

Or you may have read that “Kegel exercises are simple exercises that can be performed prior to and after having had prostate cancer treatment. This exercise helps to strengthen the pelvic floor muscles which is a system of muscles that aids the bladder and controls the flow of urine. As a result of prostate cancer treatments like surgery or radiation therapy, these muscles can weaken and when this occurs it can lead to incontinence (the inability to control urinary flow). The great news however is that with Kegel exercises you can control incontinence without need for additional surgery or medication.”2

Many websites, doctors, nurses, etc. will agree with the statements above – that it is important to work your pelvic floor muscles before and after prostate surgery in order to achieve the best possible outcome. While this is true for many men, it may not be the case for all. A recently published study pointed to what many pelvic physical therapists have known for a long time – there is not a “one size fits all” program for men after prostate surgery. 

As per the article, “It may be time to rethink advising all men to do Kegel exercises to ease stress urinary incontinence (SUI) following radical prostatectomy (RP), new study findings suggest.

The study, published in International Urology and Nephrology, reports that there may be a subset of patients for whom down-training instead of Kegel up-training may be required for maximum improvement of post-RP incontinence.”

Author Kelly M. Scott, MD, Associate Professor, Department of Physical Medicine and Rehabilitation, University of Texas Southwestern Medical Center in Dallas, and colleagues conducted a retrospective study with 136 patients with post-RP SUI and treated with pelvic physical therapy. Of these, 25 had underactive pelvic floor muscles, 13 had overactive pelvic floor muscles, and 98 had evidence of both. The mean time between surgery and the start of physical therapy was 6.8 months.

All men received therapy to either relax or strengthen their pelvic muscles. The total number of pelvic physical therapy sessions depended on a patient’s progress. Incontinence improved in 87% of them, with 58% achieving what is considered the optimal improvement of needing 2 or fewer protective pads per day. Further, pain was a problem for 27% of the men, but that proportion dropped to 14% by the end of therapy, which averaged slightly more than four sessions. In those men still experiencing pain at the end of therapy, the pain was significantly decreased (mean initial pain score 3.62 vs final mean pain rating of 1.08).

“This study is the first to demonstrate that pelvic physical therapy may be a beneficial treatment modality for men who have pelvic pain after prostatectomy, because the pain for some men may be attributable to pelvic floor myofascial pain associated with the pelvic floor overactivity issue,” Dr. Scott told Renal & Urology News.

The traditional line of reasoning is that men who have SUI after prostate removal need to do Kegel exercises because their pelvic floor muscles are too weak, Dr. Scott said. However, now it appears that men who have surgery often develop pelvic floor overactivity or muscle tightness postoperatively, and any type of pelvic floor dysfunction can lead to stress incontinence.

“We may want to move toward a more individualized approach aimed at normalizing the pelvic floor function for each man,” Dr. Scott said.

“Healthcare providers who specialize in pelvic floor problems have come to understand that Kegel exercises can worsen pelvic floor overactivity and are not the best treatment for every patient,” he said.

“We were expecting this study to show that a significant minority of men had overactivity in their pelvic floor muscles that could be contributing to their urinary incontinence, but the study actually showed that a majority of men have overactive pelvic floor dysfunction in this population. Most of the men also had some degree of muscle weakness, but not all of them,” Dr. Scott said.                

She noted that prospective, randomized-controlled studies are now warranted, and outcomes should compare basic education, a traditional Kegel strengthening program, and an individualized pelvic physical therapy program, which includes the normalization of pelvic floor overactivity as well as improvement of coordination timing and strength. Nearly all men have urinary incontinence immediately after a prostatectomy, but that percentage drops to about 5% to 20% within 24 months following RP. Men who have not seen improvement within 2 to 6 months should seek physical therapy.

Study limitations include problems with compliance, as 21% of the men did not fully adhere to treatment recommendations. Some men attended fewer physical therapy sessions than recommended or did not perform their prescribed home exercises. Another limitation was the absence of long-term follow-up to determine whether improvement in incontinence was sustained beyond the end of treatment.

Aria F. Olumi, MD, Chief of Urologic Surgery at Beth Israel Deaconess Medical Center and Professor of Surgery/Urology at Harvard Medical School, Boston, pointed out that physical therapy was started close to the time of surgery, so it is likely that many men would have experienced improvement in their urinary and pain-related issues with time.

“Given the retrospective nature of the study and lack of a control group, the study is not designed to conclude whether pelvic floor training exercises would be beneficial for patients who have undergone radical prostatectomy,” Dr. Olumi said. “However, pelvic floor training engages the patients in their rehabilitation process, and when available it’s a good resource to utilize postoperatively.”

Shubham Gupta, MD, Chief of the Division of Reconstructive Urology at University Hospitals Urology Institute in Cleveland, Ohio, said the findings from this current study should be considered hypothesis-generating rather than paradigm-shifting. The study has important methodological limitations, Dr. Gupta said, including its retrospective design, selection bias, and lack of a control group. “As such, the results are not generalizable,” Dr. Gupta said. Nevertheless, he noted that the study underscores that personalized treatment of post-RP incontinence may be warranted.

“Overall, this is an excellent preliminary demonstration of the complex role of pelvic floor dysfunction in a setting of prior prostatectomy,” said Irene Crescenze, MD, a urologist at The Ohio State University Wexner Medical Center in Columbus. The role of pelvic floor physical therapy has been used well established in the management of female pelvic floor dysfunction and urinary incontinence and it has been incorporated into various by the national organizations, she said.

“As a field, we have been slow to adapt to the role of the pelvic floor in male voiding function, and male patients have been relatively resistant to accept pelvic floor physical therapy as a treatment option,” Dr. Crescenze said. This new study, however, may convince both providers and patients of a need to seriously consider pelvic floor physical therapy as a treatment option for male patients with incontinence and pain.3

This study emphasizes the need for each individual to seek an evaluation of his pelvic floor, and follow a plan made to address the findings. As stated in the article, men can have overactive muscles after surgery. Some signs of this in men are:

  • Not being able to feel a pelvic floor muscle contraction or release
  • Pain in the penis, testicles and/or rectum
  • Urinary urgency or frequency
  • Slower urinary flow or the feeling of incomplete emptying
  • Difficulty or pain with emptying the bowels or passing ‘skinny stools’
  • Erectile dysfunction
  • Premature ejaculation

It is important not only to be evaluated after surgery but also to be assessed at intervals during recovery to determine the best treatment methods as healing takes place and progress is made.
