[10] Symptoms from a lower urinary tract infection include suprapubic pain, painful urination ( dysuria ), frequency and urgency of urination despite having an empty bladder. [ 1 ]
Blood culture - This is the process where a sample of the patient's blood is sent to the microbiology lab to attempt to isolate and grow any bacteria that may be circulating in the blood, in order to identify the pathogen. [34] This is helpful if the physician suspects infection as the underlying cause of the nephritic syndrome. [citation needed]
Bacteriuria accompanied by symptoms is a urinary tract infection while that without is known as asymptomatic bacteriuria. [1] [2] Diagnosis is by urinalysis or urine culture. [3] Escherichia coli is the most common bacterium found. [1] People without symptoms should generally not be tested for the condition. [3] Differential diagnosis include ...
Acute proliferative glomerulonephritis is a disorder of the small blood vessels of the kidney.It is a common complication of bacterial infections, typically skin infection by Streptococcus bacteria types 12, 4 and 1 but also after streptococcal pharyngitis, for which it is also known as postinfectious glomerulonephritis (PIGN) or poststreptococcal glomerulonephritis (PSGN).

Hemorrhagic cystitis or haemorrhagic cystitis is an inflammation of the bladder defined by lower urinary tract symptoms that include dysuria, hematuria, and hemorrhage. The disease can occur as a complication of cyclophosphamide , ifosfamide and radiation therapy.
Signs indicative of urethral syndrome include a history of chronic recurrent urinary tract infections (UTI) in the absence of both conventional bacterial growth and pyuria (more than 5 white blood cells per high power field). [3]
Acute pyelonephritis is an exudative purulent localized inflammation of the renal pelvis (collecting system) and kidney. The kidney parenchyma presents in the interstitium abscesses (suppurative necrosis), consisting in purulent exudate (pus): neutrophils, fibrin, cell debris and central germ colonies (hematoxylinophils). Tubules are damaged by ...
Cystitis cystica is an uncommon chronic reactive inflammatory disease that is believed to be brought on by a tumor, calculi, infection, or obstruction of the urothelium. [1] Cystitis glandularis is a proliferative progression of cystitis cystica that is distinguished by urothelial glandular metaplasia.
