Visible bugs or parasites are typical of a lice infestation, such as public lice (referred to as "crabs" sometimes). It is unlikely that lice are related to urine leaking, but it is possible for these symptoms to occur at the same time due to unrelated conditions. If you see visible bugs or parasites on your skin, seek medical attention for treatment.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Urinary Tract Infection
A urinary tract infection (UTI) is an infection of the bladder, kidneys, ureters, or urethra. E. coli, a type of bacteria that lives in the bowel and near the anus, causes most UTIs. UTI symptoms include pain, abdominal pain, mild fever, urinary urgency and frequency. Treatment involves a course of antibiotics.
Head lice infection is called pediculosis. Lice are parasites that feed on blood and can be found on the scalp and hair of infected people. Signs and symptoms of head lice infestation include a tickling sensation, itching, and sores on the head. Head lice may be eliminated with various over-the-counter shampoos and washing all clothing and bed linens in the hot water cycle. Combs and brushes should be disinfected, and the floor and furniture should be vacuumed.
Cauda Equina Syndrome
Cauda equina syndrome is a medical emergency condition that is caused by the uncommon compression of the nerves at the end of the spinal cord. Symptoms of cauda equina syndrome include lower back pain, tingling and/or numbness in the buttocks and lower extremities, bowel or bladder incontinence, and weakness in the legs. Causes of cauda equina syndrome include herniated discs, hematomas, or infection. Treatment is generally prompt surgery.
Alcohol Abuse and Alcoholism
Alcoholism is a disease that includes alcohol craving and continued drinking despite repeated alcohol-related problems, such as losing a job or getting into trouble with the law. It can cause myriad health problems, including cirrhosis of the liver, birth defects, heart disease, stroke, psychological problems, and dementia. Counseling and a few medications can be effective for alcoholism treatment.
