Vascular complications are one of the major complications in renal transplantation (RTx). Early vascular complication occurring within a few hours or days after RTx can severely compromise renal graft (RG) function and can even lead to a transplanted renal graft (RG) loss. Near-infrared spectrometry (NIRS) measuring of RG perfusion and oxygen saturation is a newly emerging and promising diagnostic procedure. Based on various studies, real-time NIRS parameters correlate with Doppler's ultrasonography (DU) RG parameters. With further advancements in technology, NIRS has a very high chance of becoming a gold standard in the monitoring of renal transplants in the future and potentially replacing today's Doppler ultrasonography. Furthermore, NIRS will potentially eliminate the inaccuracies and discrepancies caused by a physician-operating factor when compared to DU, i.e. the experience of the staff performing the DU examination of RG.
