[Attentive problem in the clinic about acute obstructive anuria at upper urinary tract].

OBJECTIVE
To improve the understanding of acute obstructive anuria at upper urinary tract in order to cope properly with corresponding clinical problems.


METHODS
The clinical problems of acute obstructive anuria at upper urinary tract in 55 patients was summarized and analysed. Anuria, lumbago, edema and progressive increase of blood creatinine and ureal nitrogen were the main bases of diagnosis. B-typed ultrasonography and plain film of abdomen (KUB) were the first choice in examinations. The treatment principles lied in prompt removal of obstruction as well as effective prevention and treatment of infection to protect renal function to maximum extent.


RESULTS
Forty-three cases (78.2%) recovered normal renal function. Ten cases (18.2%) still had azotemia three months after treatment. Two cases gave up treatment.


CONCLUSIONS
The reason of tumor for anuria should be paid attention to. The first choice in treatments is ureteral intubation by cystoscope. Diuretic should be used cautiously.
