The identification of bacteria in the urine of a child and the diagnosis requires an integrated approach in the treatment of infection, which implies not only drug therapy aimed at eliminating pain, normalizing urinary disorders, eliminating the inflammatory process, but also organizing a healthy diet, drinking plenty of fluids, and using physiotherapeutic methods. 
Antibiotic therapy for pyelonephritis is longer than cystitis or urethritis, and is 10-14 days against a week of treatment. 
The choice of antibiotic depends on the type of bacterial flora, but since it will be revealed only a few days after the delivery of urine culture, first, broad-spectrum drugs are prescribed, excreted mainly through the kidneys and maximally concentrated in the bladder, and then, if necessary, the appointment is adjusted. 
Of the entire list of antibacterial drugs, amoxicillin, ciprofloxacin, cefaclor, ceftibuten, monural are most often prescribed. 
Amoxicillin - granules in a bottle for preparing a suspension are poured with purified water to the mark on it and shaken until they are completely dissolved. Children under 2 years old are given half a measuring spoon (125 ml), from 2 to 5 years old - in full, 5-10 years old - 1-2 spoons, older - 2 tablespoons three times a day.
For newborns and very young children, the dose is calculated: 30 mg of the substance per kilogram of body weight and is divided into 2 doses, the interval between which is 12 hours.
Possible side reactions in the form of rashes on the body, nausea, upset stools, headache, tinnitus. Amoxicillin is contraindicated in case of hypersensitivity to its components, with mononucleosis, lymphocytic leukemia.
Monural is a powder packaged in sachets. Before use, it dissolves in half a glass of water. Recommended for the treatment of girls over 12 years old. Drink once a day on an empty stomach before bedtime after emptying the bladder. A side effect most often occurs from the gastrointestinal tract in the form of diarrhea, rarely dizziness. It is not prescribed for allergy to the drug.
Pain syndrome is relieved by antispasmodics: no-spa, papaverine, belladonna, baralgin.
Baralgin - prescribed for children from 13 years old on a tablet 2-3 times a day, after 15 years, the dose can be increased to 2 pieces once, the frequency is the same. The drug can cause dry mouth, exacerbation of gastritis and peptic ulcer disease, tachycardia, visual impairment. An obstacle to the use of baralgin is blood diseases, severe pathologies of the kidneys and liver, bronchial asthma.
Herbal preparations are also used to reduce inflammation. One of the most popular is urolesan.
Urolesan is a combined herbal preparation in the form of capsules, drops and syrup. For children, the most suitable form is syrup. It is taken before meals, a dose in the age range of 2-7 years 2-4 ml, 7-14 years old 4-5 ml three times a day. The drug is not used for allergies to the plants from which it is made (mint, fir, wild carrots, hops, oregano), gastritis with increased stomach acidity, peptic ulcer disease, with caution in diabetes mellitus. 
In the fight against pathogenic bacteria, vitamins A will help (the daily dose should be at least 50 thousand IU), C (1-1.5 g), but the main emphasis is on natural flavonoids - vegetables and fruits with bright colors (orange, purple, red)...
Hydrotherapy is widely used as a physiotherapeutic treatment, including the unique mineral water "Naftusya". Mineral baths, applications of ozokerite, paraffin are also used. Electrophoresis and electrotherapy are effective.
Many alternative therapy recipes focus on drinking plenty of fluids to flush bacteria out of the urinary tract.
Here are some:
- squeeze juice from the pulp of a watermelon, drink half a glass every 3 hours;
- mix 100ml of carrot juice with a tablespoon of celery leaf juice, drink 3 times a day;
- squeeze juice from 500g of fresh strawberries, drink half a glass 4 times a day.
Treatment of UTIs with herbs that have antimicrobial, anti-inflammatory, tanning, regenerating properties is very effective. These include bearberry, shepherd's bag, half-half, wild rosemary, chamomile, birch buds, lingonberry, juniper. Not only infusions, decoctions are prepared from them, but they are used for taking warm sitz baths.
Homeopathic remedies have worked well in the treatment of urinary tract infections. They not only help in the fight against inflammation, but also increase the body's defenses, activate the processes of self-regulation of its functions. Among them are Berberis (barberry), Borax (borax), Cannabis sativa (planting hemp), Cantharis (Spanish fly), Equisetum (horsetail), Petroselinum (parsley), etc.
The appointment can only be made by a homeopath, since it depends not only on the symptoms and diagnosis, but also on the sex of the child, his anatomical features, psychoemotional state. In addition, most homeopathic remedies have not been tested on children, so they are recommended only for older people.
Only severe anomalies of the urinary tract require surgical correction; in other cases, conservative treatment is sufficient.
