Memorial Hermann Sugar Land Hospital is committed to bringing innovative medical programs directly to the community, making it easy for patients to receive cutting-edge services without driving downtown. The Pelvic Health Program highlights the hospital’s dedication to this goal, and it could not come at a better time.

According to the National Institutes of Health (NIH), roughly one quarter of U.S. women are affected by  pelvic floor disorders due to weakened or injured muscles and ligaments. These disorders include urinary incontinence, fecal incontinence, and pelvic organ prolapse. And it’s not just older women who are stricken with pelvic floor disorders. Women in their 20s and 30s can fall victim, too, usually suffering from stress incontinence after childbirth.

Empowering Women to Improve Their Pelvic Floor Health

Women’s attitudes about pelvic floor problems are changing and Memorial Hermann Sugar Land  understands this evolution. Not long ago, women just tried to live with conditions such as urinary incontinence, bladder pain, pelvic pain, and more. Previously, women felt pelvic disorders were a normal part of aging and remained silent about them, often too embarrassed to seek help. Thankfully, attitudes are evolving, awareness of treatment options is growing, and women feel empowered to take control of their pelvic floor health.

“Our goal is every patient’s goal—to get you back to your normal daily activities with your family and friends,” says Dr. Brandon Sass, a recent addition to the program team.

“Our advice to women of all ages with pelvic floor problems is not to wait too long, when the problem could become worse and require more medical intervention. Patients often postpone seeing pelvic floor specialists because they believe the only solution is surgery. Our first line of treatment, when appropriate, is nonsurgical.”

An example of nonsurgical treatment for urinary incontinence is  botulinum toxin injection. A minimally invasive treatment for overactive bladder called neuromodulation can help women avoid taking prescription drugs for the condition. Dr. Dereska also notes that treatments can include physical therapy and acupuncture, further reassuring women that surgery isn’t always the only solution.

When a surgical solution is the best option for a patient who is a good candidate, the doctors strive to allay a patient’s fears about having surgery. A myriad of misconceptions about pelvic floor surgery keep women from seeking life-changing treatment. The Pelvic Health Program team aims to educate women about their options, separating fact from fiction, so every woman can make an informed decision.

Robyn Halbrook, a board certified nurse practitioner, adds,

“As a female in my mid-50s, I understand first-hand how unpleasant pelvic floor issues can be. Many of our patients are so overwhelmed and worried they are even reluctant to leave their house. We provide a place where women feel safe to talk openly about their symptoms and concerns. Our office atmosphere is warm, welcoming and professional, and we strive to create a strong bond and trusting relationship with each of our patients.”

Affiliated with Memorial Hermann Sugar Land, Dr. Brandon Sass specializes in female pelvic medicine and reconstructive surgery and obstetrics and gynecology. He completed his medical degree, residency, and fellowship in female pelvic medicine and reconstructive surgery at McGovern Medical School at The University of Texas Health Science Center at Houston (UTHealth). His interest in becoming a physician was born out of a deep desire to help people, especially women, with life-changing medicine.

“It’s remarkably gratifying to change someone’s life and help them get back to enjoying the things they love to do. I go home at the end of the day feeling good knowing I’ve helped make a real difference through my work,” he says.

Dr. Sass believes in treating the whole patient, not just the symptoms, and listening with compassion and understanding. “When I’m talking with a patient about options, I always ask myself, ‘What would I do if she were my mom, sister or aunt?’ I never recommend anything I wouldn’t recommend to my own loved ones,” he says.
