What renal failure diagnosis? Under normal circumstances, you want timely
discovery of the disease renal failure, patients will need to discover through
timely diagnosis. Therefore, do not understand this knowledge, we need to look
at, it is necessary, after all, this disease will develop, and the development
of late is uremia.
First, the medical history and symptoms, it is renal failure diagnosis
essential. Past history of more than a variety of glomerulonephritis,
pyelonephritis, hypertension, diabetes and gout disease. Early often anorexia,
nausea, vomiting, headache, fatigue and nocturnal enuresis, the gradual
emergence of oliguria, edema or high blood pressure. Most patients mouth odor,
mouth ulcers, nasal bleeding or gastrointestinal bleeding, may have difficult to
focus attention, unresponsive, numbness, drowsiness or agitation, anxiety and
other neuropsychiatric symptoms, severe incontinence and even coma. Chest
tightness, shortness of breath, precordial discomfort, suggesting concurrent
uremic cardiomyopathy, cough, expectoration, or hemoptysis, night can not be
supine, suggesting pulmonary edema or uremic pneumonia. Few patients chest
tightness, persistent chest pain, or with varying degrees of fever, which may be
pericardial effusion. Such as skin itching, pain or muscle twitching, or even
walking inconvenience, suggesting concurrent secondary hyperparathyroidism or
renal osteodystrophy. Patients prone to suffer from various infections such as
respiratory tract infections, urinary tract infections or skin infections.
Second, laboratory tests, for this examination is able to accurately detect
whether we suffer from renal failure disease. The first is the urine. Decreased
urine specific gravity or fixed, urinary protein positive, there are varying
degrees of hematuria and casts. Followed by blood. Reduction of hemoglobin and
red blood cell count, hematocrit and reticulocyte count reduction, some patients
reduce blood cells of three lines. Finally, the biochemical tests. GFR50 ~ 80ml
/ min, blood urea nitrogen, creatinine normal renal insufficiency decompensated.
GFR50 ~ 20ml / min, serum creatinine 186 ~ 442μmol / L, urea nitrogen than
7.1mmol / L, renal insufficiency decompensated. GFR20 ~ 10ml / min, serum
creatinine 451 ~ 707μmol / L, urea nitrogen 17.9 ~ 28.6mmol / L to renal
failure. GFR less than 10ml / min, serum creatinine greater than 707μmol / L,
urea nitrogen 28.6mmol / L or more, end-stage renal failure. Renal failure,
often accompanied by low calcium hyperphosphataemia, metabolic acidosis.
Fourth, we want to diagnose the disease renal failure, in addition to the
above detection, we need to carry out imaging examination. B ultrasound showed
renal shrinkage, echogenic renal cortex. Radionuclide renal dynamic developing
shows glomerular filtration rate and renal excretion dysfunction. Radionuclide
bone scan showed symptoms of renal osteodystrophy. Chest X-ray shows pulmonary
congestion or pulmonary edema, increased cardiothoracic ratio or pericardial
effusion, pleural effusion.
Thus, by the above detailed description, for renal failure that how to
diagnose the disease, surely we have a new understanding. If you still have
problems, you can ask us by email: kidneyhospitalabroad@hotmail.com.
