What's wrong with frequent urination at night and lower back pain?

If you want to maintain a good sleep, try not to get up at night. In other words, sleeping through the night is the ideal sleeping state. But why do you have frequent urination and lower back pain at night? This may be a urinary tract infection, an inflammation caused by bacteria. When urinary system diseases occur, they must be treated actively, otherwise it is easy to cause various complications. Some people even ignore early treatment and end up being hospitalized.

Urinary tract infection, also known as urinary system infection, is an inflammatory response of the urothelium to bacterial invasion, usually accompanied by bacteriuria and pyuria

Causes

More than 95% of urinary tract infections are caused by a single bacteria. Among them, 90% of outpatients and about 50% of inpatients are caused by Escherichia coli, which can be classified into 140 types of serotypes. The urinary infection-causing Escherichia coli is of the same type as the Escherichia coli isolated from the patient's feces, and is often seen in asymptomatic bacteriuria or uncomplicated urinary infection; Proteus, Clostridium difficile, Klebsiella pneumoniae, Pseudomonas aeruginosa, and fecal Streptococcus are seen in patients with reinfection, indwelling catheters, and complicated urinary tract infections; Candida albicans and Cryptococcus neoformans infections are often seen in patients with diabetes and those using glucocorticoids and immunosuppressants and after kidney transplantation; Staphylococcus aureus is often seen in bacteremia and sepsis caused by skin trauma and drug addicts; although viral and mycoplasma infections are rare, they have tended to increase in recent years. Various bacterial infections are seen in indwelling catheters, neurogenic bladder, stones, congenital malformations, and vaginal, intestinal, and urethral fistulas.

diagnosis

1. Medical history collection

(1) Clinical manifestations of urinary tract infection-related symptoms, characteristics, duration and associated symptoms;

(2) Past medical history, medication history, and related disease history to find possible causes of the disease, concomitant diseases, previous drug treatment history, and factors that may affect the development and outcome of the disease;

2. Physical examination

Includes urogenital examination; abdominal and renal examination. Pelvic and rectal examinations are helpful in identifying other concurrent diseases.

3. Auxiliary examination

(1) Laboratory tests include routine blood tests, routine urine tests, urine smear microscopic examination for bacteria, midstream urine bacterial culture + drug sensitivity, blood bacterial culture + drug sensitivity, renal function tests, etc.;

(2) Imaging examinations include ultrasound, abdominal plain film, intravenous pyelography, etc. CT or MRI examinations can be selected if necessary.
