The frequency of Urinary stone diseases has risen steadily in recent years. About 5% of all people in Germany suffer from urinary stones. Men are more frequently affected than women. Half of those affected have to expect a stone recurrence.
Stones in the urinary tract are formed from the constituents of the urine and can occur throughout the whole urinary tract.
Renal and ureteral stones occur often due to dietary habits and metabolic diseases. Outflow obstructions in the urinary tract (Harnleiterengen, renal pelvic outlet constriction, Kelchdivertikel, horseshoe kidney, etc.) may increase the risk of the occurance of stones. Bladder voiding disorders, such as an enlarged prostate or urethral stenoses are a common cause of bladder stones.
Depending on the location and form of the stones, the symptoms they cause are varying. Some stones in the kidney do not cause any signs or symptoms, but can cause blood in the urine (Hematuria). Only after they go "journeying" the known undulating and cramping pain (colic) occur. The symptoms vary depending on the location of the stone in the ureter. Typically, colic begin as flank pain spreading into the lower abdomen of the affected side. Hat der Stein den unteren Harnleiter erreicht, können die Schmerzen in den Genitalbereich reichen. If the stone reaches the lower ureter, the pain may extend into the genital area. In addition, a frequent urination and sudden urges to urinate can happen. Nausea and constipation may also be among the symptoms of colic. The colic occur until the stone has reached the bladder.
Physical examination and taking an anamnesis
Blood and urine sampling
Ultrasound (shape and position of the kidneys, urinary obstruction, stones)
Kidney blank images with subsequent intravenous administration of contrast medium (kidney function, location of the stone)
Computed tomography (alternative)
Urinary contrast medium examination through cystoscopy (retrograde ureteral illustration), often associated with Ureteral stenting (urinary diversion)

Most of the stones that are less than 4mm will pass through the urinary tract on their own, and require no treatment. Drinking a lot of fluid, physical activity and if nescessary pain-relieving and relaxing agents are usually sufficient. A dissolution of the stones is only for the uric acid stones (urate) is possible. By moving the urine pH in the basic range, it is possible to bring the crystallized uric acid back into solution.
If the stone can not be excreted or the person concerned gets fever (sepsis-risk), the stone must be removed with instrumental procedures.
As a "stone center by the lake", we offer the complete, modern stone therapy:
Splitting and removal of ureteral stones through ureteral endoscopy (URS) For this, we have laser, ultrasonic and pneumatic lithotripters available.
Percutaneous kidney stone removal - recommended for stones that are larger than 2.5cm. Percutaneous surgery is the surest way to remove all of the stone.
Thanks to modern flexible instruments disintegration / removal of kidney stones by means of endoscopy of the kidney through the ureter (URS)
shock-wave lithotripsy (SWL) directs shock waves at the stone
of course, also laparoscopic and / or conventional open stone removal.
