Final answer:
The presence of pus in urine, known as pyuria, typically indicates a urinary tract infection, for which treatment generally includes antibiotics.
Step-by-step explanation:
Barbara's urinalysis indicated the presence of pus in the urine. This condition is known as pyuria. Pyuria is characterized by the accumulation of pus in the urine, which can include dead pathogens, white blood cells, and other debris from an infection site. It is a common symptom of a urinary tract infection (UTI), which can involve the inflammation of the urethra (urethritis), bladder (cystitis), or kidneys (pyelonephritis). UTIs are often caused by bacteria such as Escherichia coli and can result from bacteria from the lower gastrointestinal tract being introduced into the urinary tract. Treatment for UTIs typically involves antibiotics like ciprofloxacin to eliminate the infection.
