At Metro Urology of Minneapolis, urologists are at the forefront of introducing new techniques and technology, especially with respect to advanced prostate cancer care.

For a urology practice to thrive, its physicians, nurses, and administrators need to be unified in providing advanced prostate, kidney, and bladder care, said Basir U. Tareen, MD, a urologist at Metro Urology of Minneapolis. At Tareen’s practice, urologists are at the forefront of introducing new techniques and technology, especially with respect to advanced prostate cancer care.
“As a specialty, we need to be the experts in prostate cancer by offering all aspects of care, from the initial diagnosis, offering curative treatments, and providing late-stage therapies that include infusions and oral oncolytics.” said Tareen. “We want to provide the best, most up-to-date care to our patients.” In many cases, better scanning techniques and the use of advanced prostate cancer care clinics have significantly improved urologists’ ability to manage the disease.
Tareen’s group of 26 physicians was founded in 1994 and is now is the largest, independent urologic specialty practice in Minnesota.
Significant medical advancements have made it possible for Metro Urology to improve the quality of its care. Tareen noted that in 2013 the introduction of MRI-guided biopsies in prostate cancer was “practice changing.” Biopsies that use MRI-guided technology are much more accurate than the traditional ultrasound-guided biopsy and “increase the chance of finding tumors that may have otherwise been missed.”
In particular, Tareen noted the emergence of MRI-ultrasound fusion biopsy and the excitement it has generated among urologists. Clinical trials have suggested that the combination of this type of biopsy with a multiparametric MRI was more effective at detecting aggressive prostate cancer compared with either procedure alone.1 “Many urologists are describing this technology as revolutionary in terms of prostate cancer diagnosis and eventually treatment.”
Using the MRI-guided approach, urologists can more accurately locate the tumor. “This opens up the door for focal therapy,” said Tareen. He explained that MRI technology allowed his group practice to develop a focal therapy program, which was one of the practice’s short-term goals. “We are currently evaluating ablative techniques such as high-intensity focused ultrasound, cryotherapy, and laser therapy.”
Focal therapy is a general term for a variety of noninvasive techniques for destroying small tumors inside the prostate while leaving the gland intact and sparing most of its normal tissue. In appropriate situations, focal therapy can offer several advantages for men with early prostate cancer:
Joint Cancer Clinic
“I rarely perform standard biopsies anymore,” added Tareen. “It’s a big change in the standard workup. The real potential benefit of it is once you have the results, you can go back and know exactly where your biopsies were positive. You can use that information to focally target lesions.”Another innovation in practice management that Metro Urology has initiated is the creation of a joint cancer clinic in which the urology practice partners with a local, large medical oncology group. “Some urologists might not be comfortable administering cytotoxic chemotherapy such as Taxotere (docetaxel),” he said. When the joint cancer clinic was originally initiated, a medical oncologist would consult and meet with urologists once a month at the urology practice. “There’s a lot of different models that groups use, but we highly recommend doing something like this. It’s been very successful for us.”
Rather than have the patient go to the urology office, then drive across town to a second appointment with a medical oncologist, we go to the patient, said Tareen. “If I have an advanced prostate cancer patient who I think will need chemotherapy, I will schedule the patient to come in when both the medical oncologist and I are in the joint clinic. It’s great for continuity of care because everybody is on the same page.”
It has been more than a few decades since there has been a major advance in bladder cancer, and Tareen noted the excitement surrounding checkpoint inhibitors in the second-line setting. An approval for use in everyday practice, though, is at least one or two years away, he said.
Meanwhile, chemotherapy offers another viable treatment option and is best utilized through the joint cancer clinic, said Tareen. It is a challenge to treat these patients who require neoadjuvant chemotherapy. “Ideally, if somebody has muscle invasive bladder cancer, we treat with neoadjuvant chemotherapy followed by radical cystectomy. Using the joint cancer clinic has made it a lot easier for us to coordinate chemotherapy schedules.”
Honing Surgical Skills
Tareen also sees greater use of the joint cancer clinic in kidney cancer because of the chemotherapeutic agents currently available. “We don’t write a lot of prescriptions for chemotherapeutic agents, but we do work closely with the medical oncologist in the joint clinic who often takes the lead.”Another advancement to help urologists is the increased use of robotics during surgery, said Tareen. In particular, for bladder cancer, Tareen has witnessed the growing use of robotic cystectomies. “Traditionally, we have performed these as open cystectomies, but we have gradually transitioned, with close to 90% of our cystectomies performed robotically. A few urologists also perform intracorporal bowel surgeries, as well.”
The emergence of robotic technology in surgery has also been extended to partial nephrectomies, said Tareen.
Tareen attributes much of the success that the group practice has experienced to strong group leadership. “One of the biggest challenges with any new technology in a large group is getting a ‘buy-in’ from all the partners,” said Tareen. “The committee chairs for castrate-resistant prostate cancer and focal therapy, for example, serve as physician champions for a particular practice area. They are encouraged to communicate with everyone in the group.”
