Department of Urology SLK Kliniken Heilbronn - Highly efficient development of ESWL

Stone treatment in future

Lithoskop Stone diseases are typical lifestyle disorders in the 21th Century. The German’s are afflicted with kidney or urinary stones in particular and they are more or less pained.

If the calculi do not leave the body in a natural way (spontaneous voiding), the Urology Heilbronn offers various modern medicine and state of the art therapies and techniques for the stone treatment.

In addition to the innovative use of endoscopic measures and ureterorenoscopy we are spezialized in the field of technical development of ESWL (extracorporeal shock wave lithotripsy). The Department of Urology SLK Kliniken Heilbronn is the center of expertise for this revolutionary method with more than one thousand treated patients.

Prof. Chaussy, the inventor of ESWL, and Prof. Rassweiler have developed together a multifunctional Lithotriptersystem in collaboration with the Siemens company.

This flexible and highly efficient Lithotripter technology (Siemens Lithoskop) based on a combined X-ray / shock waves 'double C-arm system', and is an optimal combination of lithotripter and urodiagnostic table. The device is suitable for all applications in lithotripsy, urodiagnostics, endourology as well as in percutaneous interventions.

The principle of ESWL

With Extracorporeal Shock Wave Lithotripsy, most of the obstructive urinary tract stones can be treated on an outpatient basis . The stone is fragmented from outside the body with the help of shock waves. These fragments are then spontaneously passed with the urine by the patient.

In case of large or complicated stones which cannot be treated by ESWL alone, we have facilities and expertise with the most modern endoscopic and laser techniques at our disposal.

The stone can be accessed with the help of various endourologic techniques like Ureteroscopy (URS), Percutaneous Nephrolithotomy (PCNL) and fragmented using lasers and other energies, without the need for an open incision.


Only a small part of urinary stones is suitable for a resolution. Successful will be the method for urinary calculi composed of uric acid.

Perc. nephrolitholapaxy (PCNL)

The surgery is minimally invasive, stationary, and remove the stones through the skin. This therapy is suitable for large renal and ureteral calculi. For this, a channel placed in the renal pelvic calyceal system and the stones are separated by a nephroscope (kidney removed mirroring) or destroyed by ultrasound and suction.

In the case of smaller calculi and in children, we use miniaturized instruments ('mini-perc').

Ureterorenoscopy (URS)

We remove ureteral stones with the help of this endourologic techniques and normally in-patient. The endoscope is inserted through the meatus in urethra and the bladder into the ureter. The stones are gripped with a forceps, pulled out or fragmented by proper devices.

Intracorporeal Laserlithortipsy (LISL)

The use of high-energy light has become an important therapy modality in modern medicine.

We use the AURIGA XL Holmium-Laser for many different applications in endourology. It is highly efficient for ESWL-refractory calculi, has low recurrence rates with urethral strictures.

During laser-induced lithotripsy of urinary and biliary stones the precise endoscopic use of the AURIGA XL ensures minimum invasiveness, allowing us to perform operations with minimum discomfort for patients. Calculi in difficult- to- access areas can also be treated thanks to the small diameter of the fibres, matching with flexible endoscopes.

A further benefit concering the high-power pulses represents the fact that ensures extremely efficient fragmentation of any stone independent of it's composition.
