Pyonephrosis (from Greek pyon 'pus' and nephros 'kidney' [1]) is a dangerous kidney infection that is characterized by pus accumulation in the renal collecting system. [2] It is linked to renal collecting system blockage and suppurative renal parenchymal destruction, which result in complete or nearly complete kidney failure. [3]
Pyelonephritis is inflammation of the kidney, typically due to a bacterial infection. [3] Symptoms most often include fever and flank tenderness. [2] Other symptoms may include nausea, burning with urination, and frequent urination. [2] Complications may include pus around the kidney, sepsis, or kidney failure. [3]
A periodontal abscess can occur as the result of tooth fracture, food packing into a periodontal pocket (with poorly shaped fillings), calculus build-up, and lowered immune responses (such as in diabetes). Periodontal abscess can also occur after periodontal scaling, which causes the gums to tighten around the teeth and trap debris in the pocket.
Loose teeth, in the later stages (though this may occur for other reasons, as well) Gingival inflammation and bone destruction are largely painless. Hence, people may wrongly assume painless bleeding after teeth cleaning is insignificant, although this may be a symptom of progressing periodontitis in that person. Periodontal disease
A dental abscess is a localized collection of pus associated with a tooth. The most common type of dental abscess is a periapical abscess, and the second most common is a periodontal abscess. In a periapical abscess, usually the origin is a bacterial infection that has accumulated in the soft, often dead, pulp of the tooth.
A partial nephrectomy should be attempted when there is a kidney tumor in a solitary kidney, when there are kidney tumors in both kidneys, or when removing the entire kidney could result in kidney failure and the need for dialysis. Partial nephrectomy is also the standard of care for nearly all patients with small renal masses (<4 cm in size). [22]
Acute tubular necrosis (ATN) is a medical condition involving the death of tubular epithelial cells that form the renal tubules of the kidneys.Because necrosis is often not present, the term acute tubular injury (ATI) is preferred by pathologists over the older name acute tubular necrosis (ATN). [1]
Periapical periodontitis may develop into a periapical abscess, where a collection of pus forms at the end of the root, the consequence of spread of infection from the tooth pulp (odontogenic infection), or into a periapical cyst, where an epithelial lined, fluid-filled structure forms.
