An absence of changes in kidney tissues after an enormous number of shock waves.

Repeated sessions of unilateral extracorporeal shock wave lithotripsy (ESWL) were performed in a patient with multiple bilateral calycolithiasis who suffered from Crohn's disease of long duration and from recurrent gastric ulcers. To achieve complete clearance of stones from the left kidney it was necessary to apply 10,000 shock waves during seven sessions within five weeks. This number is exceedingly high compared to average total doses which were applied to other patients of our group (920 SW per one session).

Extracorporeal shock wave lithotripsy of gallstones with oral dissolution. Results in course of ten years in Czech Republic in correlation to indication criteria.

Background/aims: We compared the results of treatment of gallbladder stones by extracorporeal shock wave lithotripsy with dissolution during two periods to different criteria of indication. In the first period (1990-1991) we treated patients with stones up to 3 cm in diameter. In the second period (1992-1994) the indication included stones up to 1.

[Enteroclysis in the diagnosis of tumors of the cecum and ascending colon].

In two patients examination of the small intestine by enteroclysis was indicated on account of haemorrhage into the digestive tract and severe anaemia and in one patient the ultrasonographic picture arousing suspicion of Crohn's disease of the terminal ileum. Although in all instances previously colonoscopy was made, considered complete, in one instance also irrigoscopy, with a negative result, enteroclysis revealed and surgery confirmed extensive carcinomas of the caecum and colon ascendens. The authors discuss the value and problems of the applied diagnostic method.

[Biological effects of interacting shock waves. A modeling study of the effects of interacting shock waves using erythrocyte hemolysis].

Aim: The effects of high-energy shock wave on tissues were discussed in literature. The shock wave sources which were used for experiments were developed for stone fragmentation. The side effects of the applicators are generally low.
