Lithotripsy Unit

The Lithotripsy Unit of Metropolitan General is equipped with the latest-generation Dornier Compact Sigma® lithotripter, which provides highly accurate treatment for kidney, ureteral, and bladder stones.

Stone localization can be performed fluoroscopically (using a C-arm fluoroscopy system), ultrasonographically, or through a combination of both methods. Depending on the stone’s hardness and location, the frequency and energy of the shock waves are adjusted accordingly.

The treatment achieves success rates of up to 90%, as the shock wave beam is precisely focused on the stone. Thanks to the system’s pioneering technology, concentrated energy delivery to the stone is enhanced, resulting in more effective fragmentation. In this way, the stone is effectively disintegrated into small fragments that are naturally excreted through the urine, without affecting the surrounding tissues.

Throughout the lithotripsy procedure, patients can monitor the treatment process on-screen.

The examination table is ergonomically designed to ensure optimal patient positioning and maximize treatment outcomes. In addition, audiovisual amenities such as radio and television contribute to a comfortable patient experience during therapy.

Stone fragmentation with this system is painless, requires no surgery or anesthesia, and lasts approximately 30–40 minutes.

This method is usually applied in cases where the stone is located “low” in the urinary tract, near the bladder, or when extracorporeal lithotripsy has not achieved the desired result.

This technique is applied in cases where the stone is located within the kidney and is large in size, such as staghorn calculi.
