  • Other techniques that limit the morbidity of treatment for small renal cell carcinomas include active surveillance and laparoscopic or percutaneous ablation (cryoablation, radiofrequency ablation, and microwave ablation). (medscape.com)
  • selective
  • Quantitative DRS could provide a convenient and fast tool for artery identification and evaluation of the depth, spatial extent, and duration of selective tissue ischemia in laparoscopic PN. (spie.org)

  • Quantitative diffuse reflectance spectroscopy (DRS) can provide a convenient, real-time means to aid in artery identification during laparoscopic PN. (spie.org)
  • The feasibility of quantitative DRS for real-time longitudinal measurement of tissue perfusion and vascular oxygenation in laparoscopic nephrectomy was investigated in vivo in six Yorkshire swine kidneys ( n = three animals ). (spie.org)
