Common symptoms of renal papillary necrosis?

summary

Renal papillary necrosis, also known as necrotizing renal papillitis or renal medullary necrosis, is a renal parenchymal destructive complication caused by renal intramedullary ischemia and / or severe infection, usually limited to the renal papilla. Although the disease can be regarded as acute pyelonephritis in the process of outbreak, it should be attributed to chronic interstitial nephritis in essence. Common symptoms of renal papillary necrosis? Let's talk about it

Common symptoms of renal papillary necrosis?

Renal papillary necrosis can be divided into acute, subacute and chronic according to the onset, and can be divided into medullary type and papillary type according to the pathological location. Most of the patients are over 40 years old, and the female is more than the male. Chronic renal papillary necrosis is rare in children, but there are reports of acute renal papillary necrosis caused by hypoxemia, dehydration or sepsis. The clinical manifestations of renal papillary necrosis depend on the location of necrosis, the number of involved papillae and the speed of necrosis development. Acute renal papillary necrosis often occurs suddenly on the basis of the above chronic diseases, with chills and high fever,

Gross hematuria or varying degrees of hematuria and pyuria are often accompanied by acute pyelonephritis such as urinary tract irritation and low back pain. For example, renal papilla necrosis, tissue shedding or blood clot obstruction of the ureter may cause colic, oliguria or even anuria. Severe bilateral extensive renal papilla necrosis may lead to acute renal failure with rapid progress and poor prognosis, Most patients died of sepsis or complications of acute renal failure,

This kind of patients often have no obvious local symptoms due to serious systemic conditions, especially when patients have diabetes, urinary tract obstruction and cardiovascular disease, it is not easy to diagnose in time; In subacute cases, the disease is not as severe or rapid as the former, and the course of disease is longer, which can reach several weeks or months. Necrotic nipples fall off, resulting in urinary tract obstruction. Renal colic is more common, and there are symptoms of renal tissue necrosis, fall off and passing through the urinary tract, such as dysuria,

matters needing attention

In order to prevent the development of the disease leading to renal papillary necrosis stage, we should actively search for the primary disease and give timely and effective treatment, strive for time to recover renal function as soon as possible. The patients with definite diagnosis should have enough rest and pay close attention to the treatment of integrated traditional Chinese and Western medicine to delay the deterioration of renal function.
