    As Professor of Medicine and Urology at Yale School of Medicine, Dr. Daniel P. Petrylak is a pioneer in the research and development of new drugs and treatments to fight prostate, bladder, kidney and testicular cancer. For patients fighting these types of cancers, Petrylak finds recent developments in the field of immunotherapy particularly promising. “Up until recently, bladder cancer had not seen any major advancement in more than 30 years,” he says. “Studies are ongoing, but interim results are exciting so far.”

    At the Smilow Cancer Hospital, Dr. Petrylak’s position as a national leader on clinical trials for men with prostate and bladder cancer has opened up a world of treatment options for patients in New England. “We offer the latest investigational drugs for these conditions, while providing the highest level of care,” he says.

    Dr. Petrylak received his MD from Case Western Reserve University School of Medicine and joined the Yale faculty in 2012. In addition to his role as professor, he is also the co-director of the Signal Transduction Research Program at Yale Cancer Center, which studies how cancer stem cells are regulated in the body and communicate with surrounding tissue. Roughly 40 physicians and scientists in the program work together to develop the best methods for matching patients with the appropriate cancer drugs.

    One of Dr. Petrylak’s key goals is to continue to successfully translate basic research into clinical practice. “One of the most significant accomplishments in my career was moving docetaxel (an antineoplastic agent) therapy for the most advanced form of prostate cancer from phase I to III,” he says. “We ran a trial which supported its approval for the most advanced form of prostate cancer.”

  • Leslie M. Rickey

    Associate Professor of Urology and of Obstetrics, Gynecology, and Reproductive Sciences; Fellowship Director, Female Pelvic Medicine and Reconstructive Surgery

    Dr. Leslie M. Rickey specializes in helping women suffering from problems related to the pelvic floor, including weaknesses of the muscles, ligaments and connective tissue that support healthy bladder, vaginal, and bowel function. Dr. Rickey treats patients with urinary incontinence (urine leakage), overactive bladder (urinary urgency and frequency), fecal incontinence (bowel leakage), pelvic organ prolapse (when a pelvic organ like the bladder or uterus drops, or “prolapses,” down and causes vaginal pressure or bulge symptoms), and genital-urinary tract fistulas (a connection between the vagina and the bladder that causes continuous urine leakage).

    Dr. Rickey’s residency and fellowship training included a unique integration of the urology and gynecology specialties. Her training in both areas has allowed her to provide comprehensive, interdisciplinary care to women with urinary tract or pelvic floor issues.

    “Urologic conditions are interwoven with so many other health conditions,” Dr. Rickey says. “I see many women who have been avoiding activities such as exercise, hiking, swimming, or traveling due to their bladder or prolapse symptoms. It is extremely gratifying to have the ability to do an office, outpatient or minimally-invasive procedure that allows them to return to the lifestyle they enjoy.”

    Dr. Rickey is committed to furthering research and continuing to advance new studies in women’s health. For the last five years, she has served on the Urinary Incontinence Treatment Network, sponsored by the National Institutes of Health.

    “Each woman has a different complex of symptoms, lifestyle and activities that are affected by her pelvic floor symptoms. Patients also have different treatment goals,” Dr. Rickey explains. “Many of these pelvic floor conditions co-occur, so I think it is absolutely critical to go to a physician who is going to query all of the pelvic floor symptoms a woman might have, including bladder, uterus, vaginal, and bowel issues. We take a very multi-disciplinary approach to patient care.”

    With her training in public health, Dr. Rickey also seeks to empower women and involve them in their own treatment, giving her patients the information they need to make the choices that are right for them.

    “These conditions are quite common,” she says. “I always discuss a range of treatment options with my patients, from behavioral and lifestyle changes to office procedures and surgery, when appropriate. I think an educated patient can be more empowered to make lasting changes that will reduce their incontinence, prolapse and bowel symptoms.”

  • Preston C. Sprenkle

    Associate Professor of Urology; Division Chief, Division of Urology at VA Connecticut Healthcare System; Director, Urology Research Fellowship; Director, Urologic Oncology Clinical Fellowship Program

    Clinical Interests
    Prostatic Neoplasms

    Dr. Preston C. Sprenkle specializes in the treatment of urologic cancers, including prostate cancer, kidney cancer, bladder cancer, testicular cancer and sarcoma – a rare kind of cancer that grows in cells that connect or support other parts of the body, like bone or muscle.

    Dr. Sprenkle has dedicated his career to using the latest imaging technologies to improve diagnosis. He was one of the first physicians nationwide to implement the use of the Artemis Device. This machine, introduced in 2009, allows a surgeon to use 3D ultrasound technology and merge it with even more precise magnetic resonance imaging (MRI) to accurately identify cancerous tumors.

    “Skilled and experienced radiologists are rare for this relatively new technique,” Dr. Sprenkle explains. “At Yale, we are fortunate to have some of the world leaders in prostate MRI.”

    Dr. Sprenkle is also a pioneer in “focal therapy,” which allows a surgeon to treat tiny prostate lesions, rather than the whole organ. This avoids many of the side effects—such as erectile dysfunction and incontinence—that may follow the removal of the whole prostate.

    “Exciting technological advances are revolutionizing urology. Prostate cancer is very common and current treatments can majorly impact a man's sexual and urinary function,” Dr. Sprenkle says. “Developing ways to minimize the impact of prostate cancer diagnosis and treatment on a man's health and quality of life is tremendously rewarding.”

    Dr. Sprenkle believes in working with patients to come up with individualized treatment plans. “I want my patients to feel that I hear their concerns and treat them like a person. I am pleased at the end of a long consultation when they feel like they understand their disease and their options.”
