Comparison of a new-generation electroconductive spark lithotripter and the Dornier Compact Delta for ureteral calculi in a quaternary referral center.

Purpose: The Technomed Sonolith Vision is the most recently developed electroconductive lithotripter. Using a case-control study, we compared the treatment outcomes of this machine with those of the Dornier Compact Delta for ureteral calculi.

Patients And Methods: Patients (N = 107) with calculi from the ureteropelvic to the ureterovesical junction undergoing primary lithotripsy using the Technomed Sonolith Vision were identified between September 2004 and February 2005.

Treatment of lower ureteral stones using the Dornier Compact Delta lithotripter.

Background And Purpose: Lithotripsy using new-generation machines requires minimal anesthesia and so can easily be given in an outpatient setting. We report our experience with the Dornier Compact Delta lithotripter in the primary management of lower ureteral stones.

Patients And Methods: We identified 128 patients treated with SWL for lower-ureteral stones between April 1999 and August 2001.

Renal parenchymal hemostatic aids: glues and things.

Purpose Of Review: Open partial nephrectomy is now recognized as the standard of care for small renal parenchymal tumors. Significant technical problems remain with regard to performing this procedure laparoscopically, namely warm renal ischemia during occlusion of the renal vascular pedicle and renal parenchymal bleeding following tumor excision and release of pedicle control. This article reviews the recent literature in the field of renal parenchymal hemostasis and its role in improving outcomes and increasing applicability for laparoscopic nephron-sparing surgery.

Mechanisms responsible for diminished fragmentation of ureteral calculi: an experimental and clinical study.

We molded 24 synthetic stones (mean weight 680 mg., range 641 to 715) from a commercial mixture of gypsum, silica, cellulose and polyvinyl acetate. Each stone was subjected to 400 shocks on a Wolf 2300 Piezolith and groups of 6 stones were treated in 4 different modes.
