Dr. Weiner is fellowship-trained in the full spectrum of urologic cancers. While prostate cancer is the focus of his clinical practice and lab, he treats bladder, kidney, testicular, penile, and adrenal cancers with the same evidence-based, patient-first approach.

WellPrept is a free tool Dr. Weiner uses to help you organize your questions, your records, and the things that matter most to you, before we sit down together. Spending 10 minutes here makes the visit work harder for you.
Each cancer is different. The treatment plan is built around the biology of your tumor, your overall health, and what matters most to you.
From low-grade non-muscle-invasive disease managed with cystoscopic resection and intravesical therapy, to high-grade and muscle-invasive disease requiring multimodal treatment. Dr. Weiner performs:
Most kidney cancers are now caught incidentally on imaging done for unrelated reasons. The right approach depends on tumor size, location, your kidney function, and whether the disease is localized or advanced.
Testicular cancer is highly curable when treated correctly from the start. The right plan depends on histology (seminoma vs non-seminoma), stage, and tumor markers.
Penile cancer is rare in the United States but treatable with the right combination of surgical, oncologic, and reconstructive expertise. Dr. Weiner's practice prioritizes oncologic control alongside quality-of-life outcomes.
Most adrenal nodules found incidentally on CT or MRI are benign. The work-up determines who needs surgery and who can be safely observed.
Prostate cancer is the focus of Dr. Weiner's clinical practice and research lab. Robotic prostatectomy, HIFU focal therapy, active surveillance, MRI-targeted biopsy, PSMA PET coordination, and management of advanced disease.
Imaging and biomarker advances have changed how urologic cancers are evaluated. Getting the right diagnosis up front prevents unnecessary surgery and finds aggressive disease earlier.
Office cystoscopy with enhanced visualization for hematuria, urothelial cancer surveillance, and lower urinary tract symptoms.
Coordinated imaging at Cedars-Sinai for kidney mass characterization, bladder cancer staging, and adrenal nodule evaluation.
Advanced molecular imaging for prostate cancer staging and recurrence work-up, with rapid scheduling at Cedars-Sinai.
Transperineal and MRI-targeted biopsy for higher diagnostic accuracy and lower infection risk than older transrectal techniques.
Germline testing for hereditary cancer syndromes (BRCA, Lynch, VHL, BHD, HLRCC) and tumor genomic profiling to guide treatment selection.
Complex cases reviewed jointly with medical oncology, radiation oncology, pathology, and radiology so the recommended plan reflects every relevant perspective.
The vast majority of urologic cancer surgery in Dr. Weiner's practice is performed using the da Vinci robotic platform. Robotic surgery typically means smaller incisions, less blood loss, shorter hospital stays, and faster return to normal activity than open surgery, without compromising oncologic outcomes when the technique is right for the case.
Open surgery is still the right choice for some complex situations, including very large kidney tumors, IVC thrombus extending into the right atrium, and certain reoperative cases. Dr. Weiner is trained and credentialed in both.
"My husband was seeing a urologist for a mass on his kidney. Dr. Weiner performed surgery on my husband and we can't thank him enough for his skill, professionalism, kindness and compassion. He is extremely thorough in explaining the condition and surgery. We were extremely confident we were in good hands."Verified patient review · Kidney cancer surgery
A urologic oncologist is a urologist with two extra years of fellowship training devoted entirely to cancers of the urinary tract and male reproductive organs. The training covers complex cancer surgery (robotic prostatectomy, partial nephrectomy, cystectomy with neobladder, RPLND), management of advanced disease, and the science of how these cancers behave. For any patient with a urologic cancer diagnosis, a urologic oncologist offers more focused expertise than a generalist.
Yes. Although prostate cancer is Dr. Weiner's clinical and research focus, he is fellowship-trained in the full spectrum of urologic oncology and treats patients with bladder, kidney, testicular, penile, and adrenal cancers at Cedars-Sinai.
Yes. Most kidney cancer surgery (partial and radical nephrectomy) and bladder removal (radical cystectomy) are performed with the da Vinci robot when oncologically appropriate. Robotic surgery typically means smaller incisions, less blood loss, and faster recovery than open surgery.
Yes. Many patients come for a second opinion for kidney, bladder, testicular, or other urologic cancer diagnoses. We provide a written summary of recommendations you can take back to your local team if you choose.
