Experimental pancreatic islet transplant into the genito-urinary tract simultaneous to kidney transplant

Simultaneous kidney and pancreas transplant is a good treatment for both renal and pancreas insufficiency. Experimental apply of genitourinary tract for pancreas implantation is reported in this work. Twenty animals aged as average 5.5 monts (SD 1.1) and an average weight of 53 kgr were submitted to this protocol. In the day 1 a left nephrectomy is completed and the graft is perfused with University of Wisconsin solution. A partial pancreatectomy is completed at following, isolation of pancreatic islets by colagenase enzymatic digestion. Islets are dryed with Ditizone and culptured for 24 hours at 37 degrees C and 5% CO2. Day-2 a right nephrectomy is performed and orthotopic renal autotransplant using the left kidney is completed. Pancreatic islets are transplanted in 4 different locations of the genitourinary tract: renal subcapsular space, bladder submucosae, testis parenchyma and vas deferens. Day-7, all the animals were sacrifized to complete pathological study. Viable islets were isolated in bladder submucosae and testis after transdeferential injection.
