[Lithotripsy for pelvic lithiasis with the Dornier system with radiological location]. / Lithotritie pour calculs pelviens avec l'appareil Dornier à repérage radiologique.

The authors report their results with 58 patients presenting with pelvic lithiasis who were treated by extracorporeal lithotrity with the Dornier HM3 system. They describe the appropriate procedure of analgesia and emphasize the difficulties to locate the pelvic calculi, which sometimes requires resorting to urography during the treatment. Out of the 58 cases, success was total in 55 (94.83%), after one session of lithotrity in 52 of them and after two sessions in 3. In 2 of the 3 cases of failure, the calculi were monohydrated calcium oxalate stones located very high in the ischiadic incisure. Five cases of presacral lithiasis were treated in the ventral position, successfully in 3 cases and without success in 2. Thus it appears that shock wave lithotrity with the Dornier HM3 system with radiological location is highly effective for the treatment of pelvic lithiasis.

[The treatment of pelvic ureteral calculi using the Dornier lithotripter. Apropos of 20 cases]. / Le traitement des calculs urétéraux pelviens par le lithotripteur Dornier. A propos de vingt cas.

The authors report a series of twenty patients with pelvic ureteric stones treated by the Dornier lithotriptor. Sixteen men and 4 women were treated over a period of 8 months (November 1988 and June 1989). A single treatment session was sufficient to ensure destruction and elimination of the stones. This technique, which does not require anaesthesia, but at most simple neuroleptanalgesia, has a low morbidity (15%). In the series of 20 patients: the stones were completely eliminated in 16 cases, 1 case was a failure at 3 months and 3 patients were not reviewed. These results are assessed with a minimum follow-up of three months and a maximum follow-up of eight months. This simple, rapide, repeatable and effective therapeutic technique appears to constitute an alternative to operative endoscopy (flexible or rigid ureteroscopy) in the treatment of stones of the pelvic ureter.

[Comparative study of deferential permeability in rats after microsurgical vasovasotomy using the Howard technique and vasovasotomy using microsurgical low energy CO2 laser]. / Etude comparative de la perméabilité déférentielle chez le rat après vaso-vasostomie microchirurgicale selon la technique de Howard et vaso-vasostomie utilisant le laser CO2 microchirurgical á faible énergie.

Microsurgery is the technique of choice for vasectomy reversal. This study was undertaken to compare the patency of the vas deferens in rats after vasovasostomy performed either according to the technique described by Howard or using low energy Co2 laser. Two groups of rats were operated on using a surgical microscope. Results were evaluated on the external appearance and histopathological studies of the anastomosis, as well as on patency as documented by a methylene blue test. Both techniques proved satisfactory, but results were clearly better with the laser method. These findings suggest that the laser technique should be preferred in human surgery.
