Philosophy of Care
Thorough communication is critical to determine optimal, individualized management strategies for each patient. I work to ensure that every patient fully understands his or her medical condition before embarking on various treatments.
In addition, treatment decisions must be taken in the context of each patient's medical, social, and family environment. As such, I balance each patient's condition within their respective situation.
Dr. Canvasser is a fellowship-trained endourologist and minimally invasive surgeon offering care for adults with kidney stone disease, kidney obstruction, kidney cancer, and enlarged prostates. He has a special interest in the medical management and prevention of patients with recurrent kidney stones.
His surgical expertise includes complex percutaneous and ureteroscopic management of kidney stones, laparoscopic nephrectomy for kidney cancer and non-functioning kidneys, and robotic surgery, including partial nephrectomy for kidney cancer, pyeloplasty for ureteropelvic junction (UPJ) obstruction, reconstruction for kidney obstruction, and simple prostatectomy for enlarged prostates.
Dr. Canvasser's research focuses on the prevention and management of patients with complex kidney stone disease, as well as improving minimally-invasive surgical management of kidney obstruction, kidney cancer, and enlarged prostates.
