[Experimental pancreatic islet transplant into the genito-urinary tract simultaneous to kidney transplant]. / Trasplante experimental de islotes de pancreas en el tracto genitourinario asociado al trasplante renal.

INTRODUCTION AND OBJECTIVES: 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. MATERIAL AND METHOD: 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. RESULTS AND CONCLUSIONS: Viable islets were isolated in bladder submucosae and testis after transdeferential injection.
