Urinary tract infections are more common in women. They usually occur in the bladder or urethra, but more serious infections involve the kidney. A bladder infection may cause pelvic pain, increased urge to urinate, pain with urination and blood in the urine. A kidney infection may cause back pain, nausea, vomiting and fever. Common treatment is with antibiotics.

Kidney stones are hard deposits of minerals and acid salts that stick together in concentrated urine. They can be painful when passing through the urinary tract, but usually don't cause permanent damage. The most common symptom is severe pain, usually in the side of the abdomen, that's often associated with nausea. Treatment includes pain relievers and drinking lots of water to help pass the stone. Medical procedures may be required to remove or break up larger stones.

Prostatitis is a disorder of the prostate gland usually associated with inflammation. Prostatitis often causes painful or difficult urination, as well as pain in the groin, pelvic area or genitals. Bacterial infections cause some but not all cases of prostatitis.

Urethritis is inflammation of the urethra. That's the tube that carries urine from the bladder to outside the body. Pain with urination is the main symptom of urethritis. Urethritis is commonly due to infection by bacteria, most often through sexual contact. It can typically be cured with antibiotics.

Benign prostatic hyperplasia (BPH) — also called prostate gland enlargement — is a common condition as men get older. An enlarged prostate gland can cause uncomfortable urinary symptoms, such as blocking the flow of urine out of the bladder. It can also cause bladder, urinary tract or kidney problems.

Acute kidney failure occurs when your kidneys suddenly become unable to filter waste products from your blood. When your kidneys lose their filtering ability, dangerous levels of wastes may accumulate, and your blood's chemical makeup may get out of balance.

Nephrotic syndrome is a kidney disorder that causes your body to pass too much protein in your urine. Nephrotic syndrome is usually caused by damage to the clusters of small blood vessels in your kidneys that filter waste and excess water from your blood.

The nephritic syndrome is a clinical syndrome that presents as hematuria, elevated blood pressure, decreased urine output, and edema. The major underlying pathology is inflammation of the glomerulus that results in nephritic syndrome.

Diabetic nephropathy is a common complication of type 1 and type 2 diabetes. Over time, poorly controlled diabetes can cause damage to blood vessel clusters in your kidneys that filter waste from your blood. This can lead to kidney damage and cause high blood pressure.

Haematuria is the presence of blood in the urine. Haematuria can be classified into 2 types: Microscopic haematuria -where the blood is not visible and present only on testing of the urine.

Hydronephrosis is swelling of one or both kidneys. Kidney swelling happens when urine can't drain from a kidney and builds up in the kidney as a result. This can occur from a blockage in the tubes that drain urine from the kidneys (ureters) or from an anatomical defect that doesn't allow urine to drain properly.
