About Dr. Bienvenu
Husband. Father. Amateur Chef. Bad Golfer.
My clinical practice focuses heavily on urologic cancers. Taking care of and helping those who are sometimes in their most difficult journeys is very rewarding. I was born and raised in south Louisiana. I am a third-generation physician, who was fortunate enough to witness my father and grandfather care for their patients with empathy and respect.
Watching my younger brother battle cancer has been the most impactful life experience as it relates to my personal interactions with my own patients. I focus on offering patients with urologic malignancies the most technologically advanced care. Dr. Bienvenu is recognized in Newsweek’s 2024 Best Prostate Cancer Surgeons list. I strive to make sure we attain the highest levels of cancer control possible without sacrificing quality of life.
When I am not at work, I enjoy spending time with my wife and children. Outdoor activities, cooking, and watching sports are my favorite past-times.
Clinical Focus
Philosophy of Care
Cancer Surgery Is About More Than Just Curing Cancer
Dr. Bienvenu believes organ-sparing therapy represents a crucial advancement in the treatment of urologic cancers — emphasizing not just the longevity of life, but the quality of life after diagnosis and treatment.
Focal Therapy for Prostate Cancer
Focal therapy targets only the cancerous portion of the prostate, preserving healthy tissue. HIFU and NanoKnife (IRE) provide effective cancer control while prioritizing urinary and sexual function — options not available anywhere else in East Tennessee.
Precision Transperineal Biopsy
This minimally invasive technique allows for accurate sampling of prostate tissue with reduced risk of complications. By targeting specific areas, precision transperineal biopsy enhances the diagnostic process and informs more personalized treatment decisions.
Partial Nephrectomy for Kidney Cancer
Partial nephrectomy allows for removal of the tumor while conserving as much healthy kidney tissue as possible — critical in patients with solitary kidneys or those at risk of chronic kidney disease. Patients retain greater renal function post-surgery.
Bladder Preservation for Bladder Cancer
For select bladder cancer cases, partial cystectomy offers a means to remove cancerous portions while preserving healthy tissue and bladder function. When radical cystectomy is required, Dr. Bienvenu performs the full spectrum including neobladder reconstruction.
“In all these scenarios, it’s vital to recognize that successful cancer treatment is about more than just extending life — it’s about ensuring patients maintain their independence and quality of life in the process. The further I advance in my career, the more gratifying successful utilization of these approaches becomes.” — Dr. Bienvenu
