Low Blood Pressure (Hypotension)
Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include light-headedness, dizziness, and fainting if not enough blood is getting to the brain. Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.
Kidney (Renal) Failure
Kidney failure can occur from an acute event or a chronic condition or disease. Prerenal kidney failure is caused by blood loss, dehydration, or medication. Some of the renal causes of kidney failure include sepsis, medications, rhabdomyolysis, multiple myeloma, and acute glomerulonephritis. Post renal causes of kidney failure include bladder obstruction, prostate problems, tumors, or kidney stones.Treatment options included diet, medications, or dialysis.

Symptoms associated with kidney pain may include fever, vomiting, nausea, flank pain, and painful urination. Treatment of kidney pain depends on the cause of the pain.
Testicular pain, or pain in the testicle or testicles are caused by a variety of diseases or conditions such as testicular trauma, testicular torsion, varicoceles, testicular cancer, epididymitis caused by infections such as STDs, and orchitis.

Urinary incontinence in children (enuresis) is twice as common in boys as in girls and may occur during the daytime or nighttime. Nighttime urinary incontinence is also called bedwetting and sleepwetting. The cause of nighttime incontinence in children is unknown. Daytime incontinence in children may be caused by an overactive bladder. Though many children overcome urinary incontinence naturally, it may be necessary to treat incontinence with medications, bladder training and moisture alarms, which wake the child when he or she begins to urinate.
Overactive Bladder (OAB)
Overactive bladder is a sudden involuntary contraction of the muscle wall of the bladder causing urinary urgency (an immediate unstoppable need to urinate). Overactive bladder is is a form of urinary incontinence.
