Background: ROTEM® is considered a helpful point-of-care device to monitor blood coagulation in emergency situations. Centrally performed analysis is desirable but rapid transport of blood samples is an important prerequisite. The effect of acceleration forces on sample transport through a pneumatic tube system on ROTEM® should be tested at each institution to exclude a pre-analytical influence.

Because of the interposition of bony structures, extracorporeal shock-wave lithotripsy (ESWL) of middle or iliac ureteral calculi is not feasible in the conventional supine position. By a slight modification of the patient's couch allowing the prone positioning of the patient, 22 patients with calculi covered by bony structures were thus treated. The success rate of 95 percent without complications is promising and renders ESWL therapy as an alternative to ureteroscopic extraction of mid and iliac ureteral calculi.

Clinical experience with 2738 patients treated by extracorporeal shock wave lithotripsy between March 1985 and December 1988 is reported. All treatments were performed with the Dornier HM-3 lithotriptor. 34% of the patients needed auxiliary measures, consisting primarily of urological manipulation to improve urinary drainage or for better localization and/or focussing of the stones.

Distal ureteral calculi are approached by ureterorenoscopy by most authors. With increasing experience ESWL of distal ureteral calculi gained in importance. The success rate of 96.

Ureteroendoscopy is used by most authors to approach distal ureteral calculi. With increasing experience extracorporeal shock wave lithotripsy (ESWL) of distal ureteral calculi has gained importance. The success rate of 96% in a large series of 264 consecutive patients treated in this manner, confirmed the results of other authors.
