Renal Failure
Acute renal failure happens when the kidneys suddenly lose their ability to remove toxins from the urine. Typically the cause for a sudden kidney failure are acute tubular necrosis (ATN) and autoimmune kidney diseases. Other causes leading to kidney damage are acute pyelonephritis and septicemia. The symptoms indicating acute renal failure are changes in urination, lowered sensation in extremities and metallic taste in the mouth. Typical symptoms include nausea, blood in stools, swelling of feet and ankles, swelling of ankle or leg, fluid retention and fatigue. A person might also notice high blood pressure, nausea and reduced appetite. Change in mental alertness might be noticed.
A nephrologist will need to examine the patient and suggest further course of action. BUN test and blood tests for creatinine and potassium are done. Kidney ultrasound or MRI might be done to look for any stones, tumors or blockage. A person suffering acute kidney failure is hospitalized and the amount of liquid ingested in monitored. The diet has to be tailored to reduce proteins and salt. Diuretics might be prescribed for reducing fluid retention. In some cases, dialysis is done; especially when the potassium levels are abnormally high. The balance of body electrolytes is maintained.
Acute kidney failure is more common with older adults and those suffering kidney or liver disease, heart failure or diabetes. An abdominal surgery might also make you more susceptible to kidney failure. Severe dehydration, blood pressure medications and overuse of NSAIDs are other possible causes for renal failure. This condition can be life threatening if not treated in time. It can lead to chronic kidney failure or damage to the nervous system and the heart. The patient can develop very high blood pressure or loss of blood in the intestines leading to last-stage kidney disease. Treatment for kidney disease include antibiotics and iodine-based medications.
Kidney biopsy
A kidney biopsy is often recommended for those who notice blood in the urine (hematuria), excess protein in the urine (proteinuria) or progressive kidney failure. Kidney biopsy might reveal the causes for improper functioning or rejection of a transplanted kidney. If urine tests, ulrasound or CT scan reveal possible kidney problems, kidney biopsy can aid in determining the cause.
A patient undergoing kidney biopsy is given sedation through IV. The biopsy needle is inserted through the skin with the aid of ultrasound. A small sample tissue is taken for examination. There is likely to be mild soreness in the muscle and some blood in the urine for the next 24 hours. Serious complications include puncture of a major blood vessel or bleeding into the kidney. Abnormal results of kidney biopsy show signs of scarring or inadequate blood flow or signs of disease such as renal cancer. Patients with blood clotting disorder are not advised to undergo this diagnostic test. Obesity, UTI, hypertension are some factors that can affect the accuracy of kidney biopsy results.
Erectile Dysfunction
Erectile Dysfunction or Impotence is a condition where a man is unable to develop and maintain an erection during sex. Conditions that lead to impotence are medications such as anti-depressants, kidney failure, diabetes, anxiety, depression and aging. Lifestyle changes that can help treat erectile dysfunction are reducing stress, quitting smoking and exercising regularly. Oral medications for impotence are Sildenafil and Tadalafil. Viagra is one such popular medication that is used to increase blood flow and relax the muscles in the penis.
