β¦ Synopsis
Partial nephrectomy is effective in the treatment of segmental renal disease but hemostasis remains a challenge. In this preliminary investigation the Nd:YAG laser was used alone or as an adjunct to the scalpel in partial nephrectomies to determine if hemostasis could be improved. A technique of 100-W laser transection with occlusion of the renal artery was effective for partial nephrectomy and achieved complete hemostasis. Conditions of patent renal artery flow or renal cooling were associated with a reduction in necrosis depth with 100-W laser partial nephrectomies. All techniques were compatible with survival over the 5-day study period.

Sapphire tips for Nd:YAG lasers fibers have been introduced recently. The increased energy density improves the cutting effect while, reportedly, preserving the hemostatic properties of Nd:YAG laser energy. The capacity of sapphire tip laser fibers to facilitate partial nephrectomy was tested in mon
## Abstract Twentyβeight partial nephrectomies were performed on nine pigs with a simultaneous, coaxial CO~2~βNd:YAG laser at power settings of 20 W and 40 W, or with a steel scalpel. A vascular pedicle clamp was used without renal cooling. The time for hemostasis was 4.5 Β± 3.2 min (mean Β± SD) with
A dosimetry study of factors affecting the extent of tissue damage inflicted upon the canine renal cortex by the Neodymium:Yttrium Aluminum Garnet (Nd:YAG) laser was undertaken. Laser parameters and renal tissue conditions were varied independently in duplicate in the following manner: (1) power -5,
The objective of the study was to characterize the healing response of the canine prostate to laser thermal injury. The study included 20 canine prostates that underwent transurethral laser radiation. The prostates were retrieved 1 hr after laser radiation in 7 dogs (acute group), and from 3 days to
A comparative study of the 1.06 p and the 1.32 p Nd:YAG laser using a variety of delivery systems (focusing handpiece, freehand GI quartz fiber, or frosted laser scalpel) was undertaken to determine the usefulness of these modalities in performing partial nephrectomies in dogs. Variables evaluated i
