Abstrakt:	Aim: To evaluate the results of surgical reconstruction of the upper urinary tract using an autograft of testicular tunica vaginalis in experimental animals. Materials and Methods: The article presents the results of partial replacement of the renal pelvis and ureter with an autograft in 25 male dogs. The grafts were harvested by resection of the parietal layer of the testicular tunica vaginalis, which was transplanted into the region of the pelvi-ureteric junction and the proximal ureter. The upper urinary tract was drained using a ureteral stent catheter. The results were evaluated at week 1 and months 1, 3 and six after the operation. The functional state of the kidneys and ureters was analyzed using excretory urography and ultrasound; the autograft biopsy specimens were examined histologically. Results: In all cases, the viability of the autograft was completely preserved, there were no signs of secondary infection, necrosis and impaired patency in the anastomosis zone. Histological examination revealed signs of epithelialization, connective tissue substitution and neovasculogenesis in the implantation zone. Conclusion: The proposed surgical modality is an alternative method to restore normal urine flow in the upper urinary tract in obstructive urological diseases. The group of obstructive urological diseases was studied using the model of the strictures of the pelvi-ureteric junction in the intrarenal pelvis and ureteral strictures measuring up to 3-4 cm in length.
