Summary
This study introduces a novel microsurgical protocol for hamster kidney transplantation, achieving a 71% survival rate in female hamsters. Male hamsters are unsuitable due to surgical complications.
Area of Science:
- Veterinary Surgery
- Transplantation Biology
- Small Animal Models
Background:
- Experimental kidney transplantation models are crucial for advancing transplantation research.
- Hamsters have not been previously utilized for renal transplantation studies.
Purpose of the Study:
- To develop and present an original anesthetic and microsurgical protocol for orthotopic renal transplantation in hamsters.
- To establish a viable small animal model for kidney transplantation research.
Main Methods:
- A total of 152 orthotopic renal transplantations were performed under general anesthesia (acepromazine and sodium thiopental).
- The procedure involved left nephrectomy followed by left renal transplantation, including anastomosis of renal artery to aorta, renal vein to inferior vena cava, and ureter implantation into the bladder.
- Strict prevention of hypothermia was maintained throughout the surgical process.
Main Results:
- A survival rate of 71% was achieved in 45 female hamsters following contralateral nephrectomy and renal transplantation.
- Male hamsters exhibited a high risk of periureteral stenosis due to fibrosis associated with seminal vesicle dissection, making them unsuitable for this model.
Conclusions:
- The presented protocol enables successful renal transplantation in female hamsters, establishing a new small animal model for transplantation research.
- Careful surgical technique and management of potential complications, such as hypothermia and periureteral stenosis in males, are critical for successful outcomes.
