Prof. M.D. Sinan Zeren

As a 72-year-old with recurrent kidney stones, I'd seen several urologists over the years, but Dr. Zeren approached my case differently. Instead of just scheduling another lithotripsy, he spent 40 minutes reviewing my decade of scans and noticed a pattern others missed—a tiny anatomical quirk in my ureter that was causing the recurrence. He proposed a minimally invasive ureteroscopy with laser lithotripsy combined with a minor corrective procedure. At Acibadem Fulya, his team was exceptional. Six months later, I'm stone-free for the first time in 15 years. His holistic thinking changed my life.

Our 8-year-old son developed sudden, severe abdominal pain. The emergency room at Acibadem Fulya called Dr. Zeren immediately. He arrived within 20 minutes, even though it was late evening. Diagnosing a rare pediatric testicular torsion, he explained everything to us—terrified parents—with incredible calmness and clarity. He performed emergency surgery that same night, saving our son's testicle. During follow-ups, he'd kneel to talk directly to our son at his level, using dinosaur analogies to explain healing. We've never met a doctor so skilled yet so gentle with children.

I came to Dr. Zeren for what I thought was a routine prostate checkup at 55. His digital exam was so subtle I barely noticed, but his concern was immediate. He ordered specific PSA tests others hadn't suggested. When results showed aggressive prostate cancer, he didn't just recommend surgery—he created a comparative chart showing robotic vs. traditional approaches with hand-drawn diagrams. His robotic prostatectomy at Acibadem Fulya preserved everything possible. Now 18 months post-op, my PSA is undetectable, and he still personally calls with results. His vigilance caught what would have been a deadly delay.

After a mountain biking accident left me with traumatic hematuria and suspected bladder injury, I was terrified. Dr. Zeren managed my emergency with astonishing precision. He performed a cystoscopy right in the ER suite at Acibadem Fulya, identifying a complex bladder tear others might have missed. What impressed me most was how he balanced urgency with compassion—cracking a subtle joke about mountain biking risks while maintaining surgical focus. His repair was flawless, and his post-op instructions included specific breathing exercises to aid recovery. He turned a traumatic event into a masterclass in emergency urological care.
