Abstract:
The present study investigated clinical factors affecting perioperative outcomes in robot-assisted radical prostatectomy (RARP). The study included 625 Japanese cases treated with RARP between 2009 and 2017. The association between clinical factors (age, overweight status, prostate volume, clinical T-stage, nerve sparing, lympho-node dissection, and the number of experienced cases) and perioperative outcomes (operation time, estimated blood loss, catheterization duration, and perioperative complication) were analyzed. Results revealed that overweight status, prostate volume, lymph-node dissection, and the number of experienced cases were associated with operation time. For estimated blood loss, the identified risk factors were overweight status, prostate volume, nerve sparing, lymph-node dissection, and the number of experienced cases. Lymph-node dissection and the number of experienced cases were also associated with catheterization duration. Additionally, only lymph-node dissection was associated with increased perioperative complication. Taken together, the present study identified several clinical factors affecting perioperative outcomes in RARP. This information may help surgeons to estimate perioperative outcomes as well as to inform patients.

Outcomes of Glycolysis
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...
