Robotic Partial Nephrectomy
Robotic Partial Nephrectomy samer kareem 2,285 Views • 2 years ago

The robotic approach to renal surgery, particularly partial nephrectomy, has some inherent challenges, and some familiarity with the da Vinci robotic system is necessary. The surgeon must gain an understanding of the robotic arm movements and range of motion, especially in relation to the clutch and camera. The advent of robotically assisted prostatectomy in 2001 [23] paved the way for widespread accessibility to the da Vinci robotic unit and its application to renal surgery. Since that time, at least one multi-institutional survey has demonstrated superiority of the robotic approach when compared to laparoscopic for outcomes of blood loss, hospital stay and a substantially shorter warm ischemia time, while maintaining equivalence in positive margin rate, operative time and complications. [11] A transperitoneal approach is most commonly used. Prior abdominal operation is not necessarily a contraindication to this procedure, but access should be approached with regard for previous operation(s) by an experienced team.

Hemoglobin Breakdown
Hemoglobin Breakdown samer kareem 5,809 Views • 2 years ago

Red blood cells, which form one of the major constituents of blood, are characterized by the absence of nuclei, hence they are unable to undergo cellular division or generate new erythrocytes from old ones. This eventually leads to cell disintegration, which typically occurs 4 months after the fully developed red blood cells have been in circulation within the bloodstream. During the degeneration of the red blood cells, some components of the hemoglobin are excreted from the body while other parts are conserved.

Hemoglobin
Hemoglobin samer kareem 4,845 Views • 2 years ago

Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Hemoglobin is made up of four protein molecules (globulin chains) that are connected together.
