  • tumor
  • Lack of perfusion causes ischemia, so there is little time to complete the resection and get the tumor samples evaluated by the pathology lab. (onclive.com)
  • With the clampless method, the surgeons at CUC can keep the kidney perfused and send the tumor to pathology to make sure the margins are negative. (onclive.com)
  • Further studies with longer follow-up are needed to elucidate the impact of ischemia on long-term renal function and correlate it with tumor volume and renal parenchymal loss. (rroij.com)
  • Recently, methods for localizing the effects of warm ischemia to the region of the tumor via selective clamping of higher-order segmental artery branches have been shown to have superior outcomes compared with clamping the main renal artery. (spie.org)
  • There is a paucity of data for laparoscopic partial nephrectomies for this larger tumor size. (ovid.com)
  • The following parameters were recorded: patient demographics, Charlson Comorbidity Index, tumor characteristics according to the RENAL score, warm ischemia and operative times, estimated blood loss, mean hospital stay, post-operative complications referring to the Clavien-Dindo classification, renal function parameters pathologic and follow-up data. (pagepressjournals.org)
  • Starving the kidney for oxygen can cause poor function after surgery, so one of the new techniques is to selectively clamp the artery that feeds the tumor so the rest of the kidney maintains oxygen flow. (startuptechwire.com)
  • underwent
  • We established renal I/R models with Cx32 +/+ and Cx32 −/− mice, which underwent double kidneys clamping and recanalization. (biomedcentral.com)
  • A 29-yr-old, 110-kg man with a long history of recurrent left nephrolithiasis underwent partial left nephrectomy for a large left upper pole calyceal diverticulum with "milk of calcium stones" that had caused recurrent renal colic. (asahq.org)
  • tissue
  • Ischemia can cause tissue damage from a lack of oxygen and nutrients. (bio-medicine.org)
  • Post-nephrectomy, the amount of healthy remaining kidney tissue is considered to be another important factor to check the renal function. (medindia.net)
  • In 95% of the cases the kidneys join at the lower pole, the isthmus is usually composed of parenchymatous tissue and has its own blood supply. (auanet.org)
  • 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)
  • global renal
  • 2 Various vascular control methods have been described to achieve a bloodless field for tumour dissection and excision, with the traditional way being renal hilar clamping (HC) that results in global renal ischaemia. (hkmj.org)
  • cancer
  • Robotic-assisted surgery vs. laparoscopic surgery for kidney removal or rectal cancer have been compared. (medindia.net)
  • Kidney cancer (most commonly renal cell carcinoma ) is one of the top ten commonly diagnosed cancers in men and women. (medscape.com)

  • Dr. Mottrie also employed the Firefly visualization technology to evaluate the vascularization of the kidney and the cancer. (uroweb.org)
  • segmental
  • In addition, the rates of ischemia induction and recovery were compared for main renal artery versus tertiary segmental artery occlusion, and it was found that the tertiary segmental artery occlusion trends toward faster recovery after ischemia, which suggests a potential benefit of selective ischemia. (spie.org)
  • selective
  • The study explored the effect of renal ischemia using the Zenascope, comparing clamping of the main renal artery to more selective arteries including how well the instrument could tell the depth of ischemia (how good of a job the surgeon did at stopping the blood flow). (startuptechwire.com)
  • By using the Zenascope as a diagnostic tool to determine the presence or lack of bloodflow, we are eliminating the guesswork and the surgeon is able to ensure selective ischemia. (startuptechwire.com)
