More about the doctor

Uro-Oncology and Robotic Surgery

Professor Cenk Acar specializes in the surgical treatment of tumors of the genitourinary system — prostate, kidney, bladder, adrenal gland and testicle. Priority is given to robotic (da Vinci) and laparoscopic surgery — minimally invasive methods with less trauma, faster recovery and high oncological precision.

Prostate Cancer

Prostate cancer is one of the professor's main areas of practice. Robotic radical prostatectomy is used for surgical treatment.

Robotic radical prostatectomy (da Vinci) is performed through several small incisions instead of one large incision. The surgeon controls the robot's movements with high-precision 3D visualization, allowing more careful work near the nerve bundles and urinary sphincter. This can contribute to faster recovery and less blood loss compared to open surgery.

Kidney Cancer

Kidney tumors can be treated with organ preservation. Robotic and laparoscopic surgery are used for both partial and total kidney removal.

Depending on the size and location of the tumor, robotic or laparoscopic partial nephrectomy (preserving the healthy part of the kidney) or radical nephrectomy is performed. The minimally invasive approach reduces surgical trauma and generally shortens hospital stay.

Bladder Cancer

For bladder cancer requiring organ removal, robotic radical cystectomy with urinary reservoir reconstruction is used.

Robotic radical cystectomy is a minimally invasive alternative to open surgery for muscle-invasive bladder cancer. The operation involves removing the bladder and, if necessary, creating a new pathway for urinary diversion. The specific reconstruction method is discussed individually.

Adrenal Tumors

Adrenal tumors are in most cases removed laparoscopically — through several small incisions, without a large incision.

Laparoscopic adrenalectomy is the standard for benign and most malignant adrenal tumors. The minimally invasive approach reduces blood loss and pain, speeding up postoperative recovery compared to open surgery.

Testicular Cancer

If a testicular tumor is suspected, the primary treatment is surgical removal — orchiectomy, followed by determination of further management.

Radical inguinal orchiectomy is the standard first operation for testicular tumors: the affected testicle is removed through an inguinal approach. Based on the histological results, it is determined whether further observation or additional treatment is required.

Benign Prostatic Hyperplasia (BPH) — Surgical Treatment

The professor's areas of practice also include benign prostatic hyperplasia (BPH) — benign enlargement of the prostate. Depending on prostate size and the patient's condition, laser enucleation (ThuFLEP) or minimally invasive water vapor therapy (Rezūm) may be used.

ThuFLEP

ThuFLEP (Thulium Fiber Laser Enucleation of the Prostate) is a closed, laser-based prostate surgery for urinary blockage caused by benign prostate enlargement, and can be used across a range of prostate sizes.

The prostate tissue narrowing the urethra is separated along its natural surgical capsule using a Thulium Fiber Laser, without any external incision, then removed via the bladder. Advantages generally include effective bleeding control, a shorter hospital stay compared to open surgery, and the ability to send the removed tissue for pathological examination.

Rezūm

Rezūm is a minimally invasive water vapor therapy for selected patients with BPH symptoms. It is not a laser surgery — no prostate tissue is cut or removed during the procedure.

Controlled water vapor is delivered to the areas of the prostate narrowing the urethra. The thermal energy causes the treated tissue to gradually shrink over the following weeks, so improvement tends to build more gradually than with laser enucleation methods such as HoLEP or ThuFLEP. It can be a good option for patients who prefer a less invasive procedure and who prioritize preserving ejaculatory function.

The choice of treatment method depends on the stage of the disease, examination results and individual patient characteristics, and is determined after an in-person consultation or a preliminary remote review of medical records.
