Chronic renal failure patients because of poor internal environment of
disorders and immune function , and the occurrence of lung disease susceptible
to pathogenic factors in vivo , mainly uremic lung, pulmonary edema , pleural
effusion , etc.
( 1 ) uremic lung : also known as uremic pulmonary edema, pneumonia, uremia .
Its symptoms are mild kidney disease , early symptoms of uremia caused by the
body only , with the gradual emergence of kidney disease progression of mild to
moderate cough, phlegm , and a small amount of breathing difficulties . The
development of interstitial fibrosis , dyspnea, and cyanosis increased. Small
amount of hemoptysis symptoms of kidney disease are also important . Need and
cardiogenic pulmonary edema , pulmonary infection and pulmonary hemorrhage
nephritic syndrome phase identification.
( 2 ) uremic pleural disease: occurrence rate of 15 % to 20% , pleural
friction rub , chest pain or chest discomfort , shortness of breath or fever .
Pleural friction rub lasted 1 to 15 days and can be accompanied by exudation. No
relationship between blood urea nitrogen and oozing .
( 3 ) pulmonary calcification : CRF often cause soft tissue calcification ,
the lung is the most common site . The clinical manifestations of chronic
dyspnea or acute, sub acute respiratory failure, chest X-ray may be completely
normal. Stop calcium, parathyroid resection , low phosphorus diet , oral
application of alumina and calcium dialysate , increasing the number or duration
of dialysis can reverse calcification.
( 4 ) uremic pulmonary edema: is one of the common acute renal unit . When
patients with chronic renal failure , especially with oliguria , anuria , such
as sudden severe dyspnea, orthopnea , with fear , a sense of suffocation ,
pallid , lips cyanosis , sweating , cough, expectoration, may with hemoptysis
and a large pink frothy sputum , lungs filled with rales symmetry and wheeze ,
increased heart rate , pulse weak and should be considered in acute pulmonary
edema.
