Preferred Practice Pattern

  • As of January 2013, the APTA Guide to Physical Therapist Practice does not include practice patterns for organ system pathology; therefore, the associated or secondary musculoskeletal, cardiovascular/pulmonary, or potential neuromuscular patterns would be indicated.1

Key Features


  • Can occur in any component of the urinary system: upper UTIs (kidneys and ureters) and lower UTIs (urethra and bladder)

  • Sudden onset of confusion in elderly without fever

  • Severe pain with or without attempts at urination in males and females or no pain at all, especially in the elderly and children

  • Changes in color, volume (decrease), and odor of urine

  • Most common in bladder and urethra

    • Cystitis

    • Urethritis

  • If spread to kidneys, symptoms more severe, and pain is located in the lower back with possible tenderness to palpation of the kidneys

Essentials of Diagnosis

  • Difficulty urinating

  • Painful urination

  • Malodorous urine

  • Pelvic pain in women

  • Rectal pain in men

  • Change in color of urine

  • Positive cultures

General Considerations

  • Diagnosis for more occult problems may take time and require intensive medical diagnostic testing

  • May refer pain to back, pelvic region, or rectal area (men)

  • May result in secondary problems such as

    • Aerobic capacity and muscle endurance impairment

    • Sarcopenia

    • Weakness/impaired muscle performance

    • Musculoskeletal problems

    • Neuromuscular problems

  • May mimic colon cancer or tumors, irritable bowel, colitis, or gynecological problems in females such as endometriosis, uterine fibroids, or ectopic pregnancies

  • May or may not be associated with fever


  • More common in women than men in general

  • Women more susceptible to cystitis, secondary to the anatomical proximity of the urethra to the anus and the urethra to the bladder

  • Frequently associated with sexual intercourse

  • Women more susceptible to urethritis because of anatomical proximity of urethra to vagina, and can be caused by sexually transmitted diseases such as herpes, gonorrhea, and chlamydia

  • About half of all women will have a UTI in their lifetime

  • Children are at greater risk, 8% of girls and 2% of boys will acquire UTIs in childhood.2
