Simultánní transplantace ledviny a Langerhansových ostrůvků (LO) je v současné době léčebnou alternativou pro pacienty s diabetem 1. typu a chronickým selháním ledvin, kteří nejsou pro vyšší operační riziko vhodní k orgánové transplantaci ledviny a pankreatu. Transplantace LO představuje ve srovnání s transplantací celého pankreatu menší riziko pooperačních komplikací, na druhou stranu je dlouhodobě stále ještě méně efektivní.
Simultaneous kidney and islet transplantation is recent therapeutic alternative for diabetics with end-stage kidney disease, who are not acceptable for simultaneous pancreas-kidney transplantation. Islet transplantation has less complications but still worse long-term function compared to whole pancreas transplantation.

BACKGROUND: The two-layer organ preservation method (TLM) based on oxygenated perfluorocarbon overlaid with University of Wisconsin (UW) solution has been successfully used in clinical islet and experimental heart and intestine transplantation. We tested whether this technique would prevent tissue damage and improve kidney function in a model of syngeneic kidney transplantation with prolonged ischemia time. METHODS: Kidneys were stored for 24 h either in UW solution (n = 16), with TLM (n = 16) or transplanted immediately (control group, n = 12). In half of the animals, survival was observed and in the other animals grafts were procured for semiquantitative histological scoring and TUNEL apoptosis assessment 24 h after transplantation. RESULTS: One-month survival rates in the UW, TLM and control groups were 12.5, 62.5 and 100%, respectively (UW vs. TLM, p < 0.01). Median creatinine levels 24 h after transplantation were 381, 299 and 121 microM, respectively (UW vs. TLM, p < 0.02). Histological scoring showed more severe tissue damage in the UW group than in the TLM group (p < 0.05). Apoptosis was more frequent in the UW group than in the TLM group (p < 0.05). CONCLUSION: We demonstrated for the first time that conservation with TLM significantly improves the outcome of kidney transplantation in a rat model and should therefore be further studied in larger animals.

Urinary incontinency is defined as a involuntary leakage of urine. Nothing pleasant. Hardly anybody tells people about such problems any time. Certain sensitivity of such healthy problems can lead also to often delay in visiting the doctor. The examination and treatment however can be quite simple and short.
