“…With the exception of Klein and Gittes" mention of the occurrence of vesical calculi following chromic catgut use for bladder union in a transplant setting, no reference has been made by other investigators employing a bladderbladder union using silk or other types of It is abundantly clear from the urologic literature that vesical calculi occur following both nonsurgical causes (intravesical migration of a Lippes loopz3 and indwelling catheter encrustation^'^ or following operations on the bladder.

Rat kidney transplantation update with special reference to vesical calculi

A technical update on rat kidney transplantation is given. In this study, the bladder-bladder union was made using silk, polyglycolic acid (Dexon), polyglactin (Vicryl), and chromic catgut. The propensity of these sutures to form vesical calculi was investigated in both first and second generation transplants. The results of our study indicate that there is no significant difference (P greater than 0.01) in their calculogenic ability. Special problems attendant with first and second generation kidney transplants are described. The concept and technique of second generation kidney transplants are also described.

“…Absorbable and nonabsorbable sutures used in the urinary tract have calculogenic potential. [27][28][29] In addition, a splinted uretero-ureterostomy with silastic catheters of appropriate caliber may result in specific complications such as upward gliding of the stent, clotting of the silicone tube, or possible perforation of the ureteric wall. 24 Also, the use of nylon tubes to ensure patency of the ureteral anastomosis may cause partial or total urinary tract obstruction, with uretero-pyeloectasia and consequent renal insufficiency.…”

Kidney transplantation procedures in rats: Assessments, complications, and management

Kidney transplantation in rats is an experimental model often used for the development of general microsurgical or transplantation techniques, for immunologic studies, and for analyzing transplant-associated long-term arterial blood-pressure changes. The aim of the present study was to analyze different surgical techniques of kidney transplantation in rats, with emphasis on minimizing surgical complications and establishing guidelines for their prevention and management. Complications were categorized into general (e.g., core body temperature drop, ischemic time) and surgically related vascular and urinary tract complications. In conclusion, a significant reduction of the complication rate in renal transplantation in rats can be achieved by placing the animal on a heating pad at an appropriate temperature. To reduce the risk of vascular thrombosis, ice-cold saline with heparin and careful flushing of the donor kidneys are recommended. Vascular complications can be avoided by performing "end-to-end" anastomosis techniques. The use of stents and cannulas in the urinary tract is associated with a high risk of urinary tract obstruction, and therefore is not recommended.

Kidney transplantation in rats: An appraisal of surgical techniques and outcome

Renal transplantation in rats is an essential experimental tool in transplantation research. The surgical procedure per se could affect the outcome of an experiment, independent of the hypothesis addressed, therefore requiring a standardized method which should be comparable across studies. To date, however, there is little information on the optimal surgical technique. We performed a Medline search on original articles published between 1965-2001 in order to evaluate whether specific technical issues affecting the outcome of the procedure could be defined. Articles that reported on a novel microsurgical procedure, or whose main purpose was the outcome of a surgical technique itself, were included in the analysis. From 2,060 retrieved publications, 34 corresponded to the selection criteria (rats and microsurgery and technique and kidney or renal transplantation). Among the essential determining factors for a good outcome, body weight >200 g and warm ischemic time <30 min were identified. Other important factors were the techniques used for vascular (end-to-end and end-to-side procedure or sleeve technique) and ureteral (bladder patch or end-to-end procedure) anastomosis. Gender, animal strain, type of anesthesia, prophylactic administration of antibiotics, and type of flushing solution did not affect the success of renal allografts. In order to avoid a bias related to the surgical procedure in rat renal transplantation, a warm ischemia time <30 min in animals with a body weight >200 g seems to be essential. Also, end-to-end or end-to-side vascular anastomoses are preferable to the sleeve technique. Other factors do not influence the immediate function of the graft.
