Researchers studied 165 men who underwent radical prostatectomy in which prostate glands were removed due to cancer.
They found that those who were not obese and were exercising regularly before surgery had the lowest prevalence of long-term urinary incontinence.
Even obese men who were physically active before surgery were less prone to the condition.
The findings suggest that men can take certain lifestyle measures to cut their risk of lingering urinary incontinence, said lead researcher Dr. Kathleen Y. Wolin, an assistant professor of surgery at Washington University School of Medicine in St. Louis.
She added that men who had a regular exercise of 15 minutes per day had lower death rates than inactive men during the two-decade study period.
