Prostate Cancer Blood Loss Potency Rates Arista™ Ah

ClinConnect Summary

This clinical trial is studying the effects of a special substance called ARISTA™ AH, which is applied during robotic-assisted surgery for prostate cancer, to see if it can help reduce blood loss and improve erectile function after the operation. The trial aims to find out if using this substance can lead to higher levels of hemoglobin, which is an important measure of blood health, and if it can help men maintain their erectile function after surgery.

Men aged 45 to 68 who have been diagnosed with prostate cancer and are planning to undergo this type of surgery may be eligible to participate. To join the study, participants should have a certain level of urinary control and erectile function before the surgery. During the trial, participants will be randomly assigned to receive either the ARISTA™ AH application or standard care, and they will be monitored for their recovery, including blood loss and changes in erectile function. This trial is important because it could lead to better surgical outcomes and improved quality of life for men undergoing treatment for prostate cancer.

  • SURGICAL AND PERIOPERATIVE EXLUSION CRITERIA:
  • Accessory pudendal arteries (APA) preservation, if an APA is identified
  • For a) nerve sparing and b) controlling bleeding in the area of the prostate bed and neurovascular bundles after prostate removal, no monopolar thermal application are allowed but suturing and clip application is allowed. For secondary resection of the neurovascular bundle and controlling bleeding, mono- or bipolar thermal application, clip application and suturing is allowed.
