Kidney dysfunction after non renal solid organ transplantation.

Chronic kidney disease developed after non renal solid organ transplantation in a significant issue. Evaluation of kidney function starting form a complete history and physical examination, then an accurate measurement of renal function and a urinalysis, followed by kidney imaging study should be performed prior to transplantation. Moreover, probability of reversibility of kidney dysfunction and the risk of progression to end stage renal disease should be assessed. During peri- and postoperative period hypotensive episodes should be avoided or at least minimized. Good blood pressure control (however, no guidelines for target blood pressure values for non solid organ transplants are available) as well as tight control of diabetes and hyperlipidemia should be implemented. Proteinuria, if present, should be attenuated by the use of therapeutic modalities (RAS blockade) to prevent or delay the progression of renal failure. The ability to identify CKD may allow early implementation of treatments that could arrest or delay the progression of renal damage, enable effective treatment of its complications, and reduce the risk of drug-induced nephrotoxicity. Kidney function should be monitored in nonrenal solid organ transplant recipients as an important risk factor comparable with diabetes for cardiovascular mortality and morbidity. In presence of existing nephron sparing immunosuppressive regimens, early detection of deteriorating kidney function gives the opportunity to tailor the treatment. A multidisciplinary approach for these patients including also a nephrologist should be considered.
