Medical treatment entails low dose antibiotic prophylaxis until resolution of VUR occurs. Antibiotics are administered nightly at half the normal therapeutic dose. The specific antibiotics used differ with the age of the patient and include:

- Amoxicillin or ampicillin – infants younger than 6 weeks

- Trimethoprim-sulfamethoxazole (co-trimoxazole) – 6 weeks to 2 months

After 2 months the following antibiotics are suitable:

- Nitrofurantoin {5–7 mg/kg/24hrs}

- Nalidixic acid

- Bactrim

- Trimethoprim

- Cephalosporins

Urine cultures are performed 3 monthly to exclude breakthrough infection. Annual radiological investigations are likewise indicated. Good perineal hygiene, and timed and double voiding are also important aspects of medical treatment. Bladder dysfunction is treated with the administration of anticholinergics.

Endoscopic injection involves applying a gel around the ureteral opening to create a valve function and stop urine from flowing back up the ureter. The gel consists of two types of sugar-based molecules called dextranomer and hyaluronic acid. Trade names for this combination include Deflux and Zuidex. Both constituents are well-known from previous uses in medicine. They are also biocompatible, which means that they do not cause significant reactions within the body. In fact, hyaluronic acid is produced and found naturally within the body.

Even when caught early, aggressive treatment is required (Bobba). Antibiotics are proven to cure Emphysematous cystitis over time and reduce the amount of gas inside the bladder wall. Prognosis is poor if antibiotics are not used to treat the patient. Additional treatment consists of urinary drainage and good control of blood glucose. The treatment of underlying comorbid diseases, such as diabetes, is extremely important because they can intensify the infection (Gheonea, Bondari). Hyperbaric oxygen is an effective treatment, and has cured some cases in as little as 48 hours. Although it is unclear as to how gas formation occurs in emphysematous cystitis, it’s dependant on whether or not the patient has contributing diseases (Mccabe). Gas formation in diabetic patients diagnosed with Emphysematous cystitis has been determined to occur due to the production of carbon dioxide as a result of the fermentation of the high concentrations of glucose. Gas formation in nondiabetic patients is most likely due the breaking down of urinary lactulose and tissue proteins. Inflammation caused by infection increases pressure and decreases circulation, which provides the perfect environment for bacteria to produce gas (Sereno).

Treatment can include amoxicillin-clavulanic acid, intravenous fluid administration and paracetamol oral for pain relief. Other treatment varies based on the condition and extent of uropathy.

Often, aggressive treatment is unnecessary for people with MSK disease that does not cause any symptoms (asymptomatic). In such cases, treatment may consist of maintaining adequate fluid intake, with the goal of decreasing the risk of developing kidney stones (nephrolithiasis). Cases of recurrent kidney stone formation may warrant evaluation for possible underlying metabolic abnormalities.

In patients with low levels of citrate in the urine (hypocitraturia) and incomplete distal renal tubular acidosis, treatment with potassium citrate helps prevent the formation of new kidney stones. Urinary tract infections, when they occur, should also be treated.

Patients with the more rare form of MSK marked by chronic pain typically require pain management. Non-obstructing stones in MSK can be associated with significant and chronic pain even if they're not passing. The pain in this situation can be constant. It is not certain what causes this pain but researchers have proposed that the small numerous stones seen in MSK may cause obstruction of the small tubules and collecting ducts in the kidney which could lead to the pain. This pain can often be debilitating and treatment is challenging. Narcotic medication even with large quantities is sometimes not adequate. Some success with pain control has been reported using laser lithotripsy (called “ureteroscopic laser papillotomy”).

People with acute pyelonephritis that is accompanied by high fever and leukocytosis are typically admitted to the hospital for intravenous hydration and intravenous antibiotic treatment. Treatment is typically initiated with an intravenous fluoroquinolone, an aminoglycoside, an extended-spectrum penicillin or cephalosporin, or a carbapenem. Combination antibiotic therapy is often used in such situations. The treatment regimen is selected based on local resistance data and the susceptibility profile of the specific infecting organism(s).

During the course of antibiotic treatment, serial white blood cell count and temperature are closely monitored. Typically, the intravenous antibiotics are continued until the person has no fever for at least 24 to 48 hours, then equivalent antibiotics by mouth can be given for a total of 2–week duration of treatment. Intravenous fluids may be administered to compensate for the reduced oral intake, insensible losses (due to the raised temperature) and vasodilation and to optimize urine output. Percutaneous nephrostomy or ureteral stent placement may be indicated to relieve obstruction caused by a stone. Children with acute pyelonephritis can be treated effectively with oral antibiotics (cefixime, ceftibuten and amoxicillin/clavulanic acid) or with short courses (2 to 4 days) of intravenous therapy followed by oral therapy. If intravenous therapy is chosen, single daily dosing with aminoglycosides is safe and effective.

Treatment of xanthogranulomatous pyelonephritis involves antibiotics as well as surgery. Removal of the kidney is the best surgical treatment in the overwhelming majority of cases, although polar resection (partial nephrectomy) has been effective for some people with localized disease. Watchful waiting with serial imaging may be appropriate in rare circumstances.

Uncomplicated infections can be diagnosed and treated based on symptoms alone. Antibiotics taken by mouth such as trimethoprim/sulfamethoxazole (TMP/SMX), nitrofurantoin, or fosfomycin are typically first line. Cephalosporins, amoxicillin/clavulanic acid, or a fluoroquinolone may also be used. However, resistance to fluoroquinolones among the bacterial that cause urinary infections has been increasing. The FDA recommends against the use of fluoroquinolones when other options are available due to higher risks of serious side effects. These medications substantially shorten the time to recovery with all being equally effective. A three-day treatment with trimethoprim, TMP/SMX, or a fluoroquinolone is usually sufficient, whereas nitrofurantoin requires 5–7 days. Fosfomycin may be used as a single dose but has been associated with lower rates of efficacy.

With treatment, symptoms should improve within 36 hours. About 50% of people will recover without treatment within a few days or weeks. Fluoroquinolones are not recommended as a first treatment. The Infectious Diseases Society of America states this due to the concern of generating resistance to this class of medication. Amoxicillin-clavulanate appears less effective than other options. Despite this precaution, some resistance has developed to all of these medications related to their widespread use. Trimethoprim alone is deemed to be equivalent to TMP/SMX in some countries. For simple UTIs, children often respond to a three-day course of antibiotics. Women with recurrent simple UTIs may benefit from self-treatment upon occurrence of symptoms with medical follow-up only if the initial treatment fails.

Management of pain often requires intravenous administration of NSAIDs or opioids. Orally administered medications are often effective for less severe discomfort. The use of antispasmodics do not have further benefit.

For people with hyperuricosuria and calcium stones, allopurinol is one of the few treatments that have been shown to reduce kidney stone recurrences. Allopurinol interferes with the production of uric acid in the liver. The drug is also used in people with gout or hyperuricemia (high serum uric acid levels). Dosage is adjusted to maintain a reduced urinary excretion of uric acid. Serum uric acid level at or below 6 mg/100 ml) is often a therapeutic goal. Hyperuricemia is not necessary for the formation of uric acid stones; hyperuricosuria can occur in the presence of normal or even low serum uric acid. Some practitioners advocate adding allopurinol only in people in whom hyperuricosuria and hyperuricemia persist, despite the use of a urine-alkalinizing agent such as sodium bicarbonate or potassium citrate.

In people who do not require hospitalization and live in an area where there is a low prevalence of antibiotic-resistant bacteria, an fluoroquinolone by mouth such as ciprofloxacin or levofloxacin is an appropriate initial choice for therapy. In areas where there is a higher prevalence of fluoroquinolone resistance, it is useful to initiate treatment with a single intravenous dose of a long-acting antibiotic such as ceftriaxone or an aminoglycoside, and then continuing treatment with a fluoroquinolone. Oral trimethoprim/sulfamethoxazole is an appropriate choice for therapy if the bacteria is known to be susceptible. If trimethoprim/sulfamethoxazole is used when the susceptibility is not known, it is useful to initiate treatment with a single intravenous dose of a long-acting antibiotic such as ceftriaxone or an aminoglycoside. Oral beta-lactam antibiotics are less effective than other available agents for treatment of pyelonephritis. Improvement is expected in 48 to 72 hours.

Therapy for UAB is often dependent on factors such as age, health, symptoms, and cause of the condition. Treatment frequently includes lifestyle modification (fluid restriction, bladder retraining). Bethanechol is a prescription medication used for treatment, bethanechol can stimulate the nerves of the bladder, making them more responsive to stimulus. With UAB, it is common for patients to utilize a urinary catheter to void. Surgical options are also options, with a cuff or stent placed around or in the neck of the bladder to aid the emptying and leakage of urine. Neuromodulatory techniques such as sacral nerve or posterior tibial nerve stimulation may be of value in selected cases. However, current therapies are considered inadequate and there is a strong need for new research and attention.(Van Koeveringe et al., 2011; Tyagi et al. 2015).

Management of hematuria is aimed at treating secondary causes of hematuria. If hematuria is a result of a UTI, treatment with antibiotics is usually initiated and urine testing repeated after 6 weeks. If hematuria is secondary to a kidney stone, then management depends on the size of the kidney stone. If the stone is small enough, usually less than 1 cm, then conservative management with analgesics and fluid hydration may be sufficient, however stones that are too bid may require removal by a urologist. Another common cause of hematuria is benign enlargement of the prostate (BPH), treatment is aimed at reducing the size of the bladder with medications like finasteride and symptomatic management with drugs like terazonsin or tamsulosin.

For people with exercise induced hematuria, management is conservative and involves cessation of strenuous activities and keeping hydrated. If the cause of hematuria is a result of malignancy, treatment and management depends on the type and stage of cancer and can involve chemotherapy, radiation or surgical resection of the tumor or organ involved.

Complicated UTIs are more difficult to treat and usually requires more aggressive evaluation, treatment and follow-up. It may require identifying and addressing the underlying complication. Increasing antibiotic resistance is causing concern about the future of treating those with complicated and recurrent UTI.

When in acute urinary retention, treatment of the urethral stricture or diversion is an emergency. Options include:

- Urethral dilatation and catheter placement. This can be performed in the Emergency Department, a practitioner's office or an operating room. The advantage of this approach is that the urethra may remain patent for a period of time after the dilation, though long-term success rates are low.

- Insertion of a suprapubic catheter with catheter drainage system. This procedure is performed in an Operating Room, Emergency Department or practitioner's office. The advantage of this approach is that it does not disrupt the scar and interfere with future definitive surgery.

Initial treatment is with adequate hydration, alkalization of the urine with citrate supplementation or acetazolamide, and dietary modification to reduce salt and protein intake (especially methionine). If this fails then patients are usually started on chelation therapy with an agent such as penicillamine. Tiopronin is another agent.

Once renal stones have formed, however, the first-line treatment is ESWL (Extracorporeal shock wave lithotripsy). If ESWL do not work efficiently surgery can be necessary. Both endoscopic surgery and conventional open-abdominal surgery have proven to be effective treatment modalities for patients with more advanced disease. Adequate hydration is the foremost aim of treatment to prevent cysteine stones. The goal is to increase the urine volume because the concentration of cystine in the urine is reduced which prevents cystine from precipitating from the urine and forming stones. People with cystine stones should consume 5 to 7 liters a day. The rationale behind alkalizing the urine is that cystine tends to stay in solution and causes no harm. In order to alkalize the urine, sodium biocarbonate has been used. One must be careful in alkalizing their urine because it could lead to other forms of stones in process of preventing cystine stones. Penicillamine is a drug that acts to form a complex with cystine that is 50 times more soluble than cystine itself. Percutaneous nephrolithotripsy (PNL) is performed via a port created by puncturing the kidney through the skin and enlarging the access port to 1 cm in diameter. Most of the time, cystine stones are too dense to be broken up by shock (ESWL) so PNL is needed.

Videos of surgery are available on various websites that show stone removal by percutaneous nephrolithotomy.

In February 2017, an article was published in Nature Medicine entitled 'Alpha lipoic acid treatment prevents cystine urolithiasis in a mouse model of cystinuria', suggesting that a high dose of the readily available antioxidant, alpha-lipoic acid at 2,700 mg/67 kg body weight daily reduced the incidence of stones. The effects were dose dependent. The results are unprecedented for cystinuria. A clinical trial is underway based on this mouse model.

Symptomatic bacteriuria is typically treated as a urinary tract infection with antibiotics. Common choices include nitrofurantoin, and trimethoprim/sulfamethoxazole.

Following urethroplasty, patients should be monitored for a minimum of 1 year, since the vast majority of recurrences occur within 1 year.

Because of the high rate of recurrence following dilation and other endoscopic approaches, the provider must maintain a high index of suspicion for recurrence when the patient presents with obstructive voiding symptoms or urinary tract infection.

IgG4-related disease responds well, and often dramatically, to glucocorticoid therapy, provided that advanced fibrotic lesions have not resulted in irreversible damage, and this has included resolution of radiologic findings. Men given glucocorticoids to treat IgG4-related disease at other anatomical sites sometimes report relief of their lower urinary tract symptoms, suggesting that IgG4-related prostatitis may be underdiagnosed.

Cases are however likely to get misdiagnosed as benign prostatic hyperplasia and to get treated alternatively with medications such as alpha blockers. The efficacy of alpha blockers in IgG4-related prostatitis remains unclear.

The most important criterion for improving long-term prognosis is success of the initial closure. If a patient requires more than one closure their chance of continence drops off precipitously with each additional closure - at just two closures the chance of voiding continence is just 17%.

Even with successful surgery, people may have long-term complications. Some of the most common include:

- Vesicoureteral reflux

- Bladder spasm

- Bladder calculus

- Urinary tract infections

Asymptomatic bacteriuria generally does not require treatment. Exceptions include during pregnancy and in those undergoing surgery of the urinary tract. Children with vesicoureteral reflux or others with structural abnormalities of the urinary tract.

There is no indication to treat asymptomatic bacteriuria in diabetics, renal transplant recipients, and in those with spinal cord injuries.

The overuse of antibiotic therapy to treat asymptomatic bacteriuria increases the risk of diarrhea, antimicrobial resistance, and infection due to Clostridium difficile. Other effects include increased financial burdens and overreporting of mandated catheter-associated urinary tract infection.

Treatment of hydronephrosis focuses upon the removal of the obstruction and drainage of the urine that has accumulated behind the obstruction. Therefore, the specific treatment depends upon where the obstruction lies, and whether it is acute or chronic.

Acute obstruction of the upper urinary tract is usually treated by the insertion of a nephrostomy tube. Chronic upper urinary tract obstruction is treated by the insertion of a ureteric stent or a pyeloplasty.

Lower urinary tract obstruction (such as that caused by bladder outflow obstruction secondary to prostatic hypertrophy) is usually treated by insertion of a urinary catheter or a suprapubic catheter.Surgery is not required in all prenatally detected cases.

Urinary catheters should be inserted using aseptic technique and sterile equipment (including sterile gloves, drape, sponges, antiseptic and sterile solution), particularly in an acute care setting. Hands should be washed before and after catheter insertion. Overall, catheter use should be minimized in all patients, particularly those at higher risk of CAUTI and mortality (e.g. the elderly or those with impaired immunity).

In a small minority of cases of urethral syndrome, treatment with antibiotics is effective, which indicates that in some cases it may be caused by bacterial infection which does not show up in either urinalysis or urine culture. For chronic urethral syndrome, a long term, low-dose antibiotic treatment is given on a continuous basis or after intercourse each time if intercourse appears to trigger symptoms.

As low oestrogen may also be considered a source for urethral syndrome, hormone replacement therapy, and oral contraceptive pill (birth-control pills) containing oestrogen are also used to treat the symptoms of this condition in women.

Modern therapy is aimed at surgical reconstruction of the bladder and genitalia. Both males and females are born with this anomaly. Treatment is similar.

In males treatments have been:

In the modern staged repair of exstrophy (MSRE) the initial step is closure of the abdominal wall, often requiring a pelvic osteotomy. This leaves the patient with penile epispadias and urinary incontinence. At approximately 2–3 years of age the patient then undergoes repair of the epispadias after testosterone stimulation. Finally, bladder neck repair usually occurs around the age of 4–5 years, though this is dependent upon a bladder with adequate capacity and, most importantly, an indication that the child is interested in becoming continent.

In the complete primary repair of exstrophy (CPRE) the bladder closure is combined with an epispadias repair, in an effort to decrease costs and morbidity. This technique has, however, led to significant loss of penile and corporal tissue, particularly in younger patients.

In females treatment has included:

Surgical reconstruction of the clitoris which is separated into two distinct bodies. Surgical reconstruction to correct the split of the mons, redefine the structure of the bladder neck and urethra. Vaginoplasty will correct the anteriorly displaced vagina. If the anus is involved, it is also repaired. Fertility remains and women who were born with bladder extrophy usually develop prolapse due to the weaker muscles of the pelvic floor.

The primary treatment for urethral diverticulum is surgical. The surgery is conducted transvaginally, usually when there is no acute inflammation to better aid dissection of the delicate tissues.
