Qualifications

Dr. Nir Kleinmann directs the Endourology and Kidney Stones Unit at Sheba Medical Center. He specializes in minimally invasive urologic oncology. Forbes and ResultMed named him among the Best Doctors in Israel for 2025–2026. He has authored over 60 scientific publications on urological treatments.

Specialization and Surgical Approach

Dr. Kleinmann treats conditions of the kidney and upper urinary tract. He is a pioneer of kidney–sparing laser surgery for complex tumors. The doctor uses a dual–laser system combining neodymium and holmium technologies. This approach preserves organ function while maximizing cancer control.

His clinical focus includes these key areas:

Upper tract urothelial carcinoma (UTUC)
Kidney, prostate, and bladder cancer
Complex kidney and urinary stones
Benign prostatic hyperplasia (BPH) — a noncancerous enlargement of the prostate gland
Urethral strictures and varicocele

Achievements and Clinical Research

Dr. Kleinmann is an investigator in the OLYMPUS clinical trial. This research focuses on chemoablation treatments for upper tract urothelial carcinoma. Chemoablation uses medication to dissolve tumors without traditional surgery. As a result, he prioritizes precision techniques that reduce surgical trauma and recovery time.

The doctor treats over 20 different urological conditions using advanced endoscopic methods. These methods involve using thin, flexible tubes with cameras to perform surgery through natural body openings.
