Hypovolemia , renal vascular thrombosis, renal artery anastomotic stenosis , perirenal hematoma , compression of the renal cyst when lymph vessels, renal perfusion is limited, renal ischemia can cause oliguria after renal transplantation . But their corresponding performance , generally difficult to identify.
2 , urinary tract obstruction
Vesicoureteral anastomotic stenosis or blockage of blood clots , catheter blockage , a sudden decrease in amount of urine or no urine within 24 to 48 hours after surgery . By flushing the catheter , cystoscopy or ureteral catheter insertion , can be identified.
3, there are foci of infection in vivo , although not serious , but low body resistance, can also cause fever, chills , decreased urine output , serum creatinine, blood urea nitrogen and other changes, can induce acute rejection . Often occurs within three months after surgery . Mostly lung infection , urinary tract infection , but also as a systemic infection . Should be lung X-ray, urine culture , blood culture , etc., carefully looking foci may exist , in order to avoid delaying treatment .
4 , drug toxicity
Certain drugs , such as gentamicin , kanamycin , neomycin Pioneer , a certain renal toxicity. When renal function is not yet stable , such as improper application , can cause renal dysfunction, oliguria , anuria , serum creatinine , blood urea nitrogen increased. A larger dose , longer history , significant changes in urine protein , tube more difficult to identify
