Lithotripsy

lithogold380® – the new generation of devices in ESWL for a gentle therapy of urolithiasis

Lithotripsie

Renal stones are one of the most painful affections of the urinary tract. The affection rate in Central and Western Europe accounts for about 5 % of the population whereas men, usually aged between of 30 and 50, are affected more frequently than women.  The morbidity rate in Central and Western Europe is about 5 % of the population whereas men are affected more frequently than women. The extracorporeal shock wave lithotripsy (ESWL) was introduced as a non-invasive therapy solution for renal stones in 1980. Today it is the most common treatment method for urolithiasis. ESWL is characterised by a great success of the therapeutic outcome as well as low side effects.

How does ESWL work & why is the stone therapy with the lithogold380® so successful?

The therapy of urolithiasis with the lithogold380 makes particular use of the physical-acoustic effect of Spark Waves. Spark Waves are generated extracorporeal and passed through the skin by means of a water cushion. The concentrated acoustic Spark Wave energy is focused and directed onto the area where the stone is located. Once the sound wave of the Spark Waves hits the renal stone it takes a few thousand pulses until it is pulverized into sand grain-sized particles which can be released through the ureter.

The specially designed large focus of the lithogold380 combined with lower peak energy allows an especially effective and kidney-conserving therapy. The large focus of the system completely encloses the renal calculus and concentrated Spark Wave energy exerts its effect evenly on the entire stone and disintegrates it; referred to as “squeezing effect”. The success rate of stone fragmentation is about > 95 %. The retreatment rate with lithogold380 has been reduced down to < 7 %.

Another advantage of the lithogold380 is the limited maximum pressure of the therapy system which guarantees an especially gentle treatment for the renal tissue reducing anaesthesia to a minimum.

Which urological indications are approved for the Spark Wave® therapy with lithogold380?

  • Renal calculi
  • Ureteral calculi

How is the Spark Wave® treatment with lithogold380® performed?

The treatment of kidney stones is carried out on an outpatient or inpatient basis, usually requiring no general anaesthesia. Generally, it is sufficient to ease the patient through analgesics. During the procedure, the renal stones are first located by means of X-ray or ultrasound. Subsequently, ultrasound gel is applied and the therapy head is put on top releasing the Spark Waves to the affected area. The quantity of applied Spark Waves depends on the type of stone. The recovery time for ESWL-treated patients is usually quite short. After only a few days, the patient is able to participate in daily life again.

Treatment duration & number of treatments

Generally, a single ESWL treatment is sufficient to successfully disintegrate the calculus.

How successful is the stone therapy with the lithogold380®?

95 % of all patients are free of symptoms and pain after a single treatment with the lithogold380.

Which side effects may occur?

It could be possible that there is some blood in the urine shortly after the treatment. The area treated, during the Spark Wave treatment, may show temporary redness and / or a momentary feeling of discomfort.
