Inflammation of the Bladder (Cystitis): Or something else? Differential Diagnosis

Infectious and parasitic diseases (A00-B99).

  • BK (polyoma) virus infection – in immunocompromised patients, BK virus (polyoma virus) can lead to hemorrhagic cystitis (cystitis of the bladder with severe, visible blood admixture to the urine)
  • Gonorrhea (gonorrhea)
  • Genital herpes – sexually transmitted disease caused by the herpes virus.

Neoplasms – tumor diseases (C00-D48).

Psyche – nervous system (F00-F99; G00-G99)

  • Psychosomatic complaints, unspecified

Genitourinary system (kidneys, urinary tract – reproductive organs) (N00-N99).

  • Acute pyelonephritis (inflammation of the renal pelvis).
  • Chronic prostatitis (prostatitis).
  • Chronic pyelonephritis (inflammation of the renal pelvis).
  • Endometriosis – painful, chronic disease of women in which the lining of the uterus (endometrium) occurs outside the uterine cavity, for example, in the ovary (ovary) or vesica urinaria (urinary bladder).
  • Urinary bladder stones
  • Interstitial cystitis (interstitial cystitis, IC; synonym: Hunner’s cystitis) – bladder inflammation of unclear etiology occurring predominantly in women with fibrosis of the bladder muscles, urge incontinence (irritable bladder or overactive (hyperactive) bladder) and development of a shrinking bladder; confirm diagnosis by: Urethrocystoscopy (urethral and bladder endoscopy) and biopsy (tissue sampling) for histology (fine tissue examination) and molecular diagnostics of specific cell proteins.
  • Neurogenic bladder disease – congenital or acquired reduction or cancellation of the state of tension of the muscles of the urinary bladder.
  • Perivesical inflammation – inflammation affecting the area surrounding the urinary bladder.
  • Radiogenic cystitis – occurrence of cystitis after radiation therapy (radiatio, in cancer).
  • Irritable bladder (synonyms: urethral syndrome, Frequenca urgency syndrome; overactive bladder) – functional disorder of bladder function without organ pathological findings; the irritable bladder occurs especially in women in the 3rd to 5th decade of life.
  • Salpingitis – inflammation of the fallopian tube (tube).
  • Urethritis (inflammation of the urethra)
  • Vaginitis (vaginitis)
  • Vulvovaginitis – inflammation of the female external genitals, including the vagina.
  • Cystitis follicularis – inflammation of the bladder associated with nodule formation.

Injuries, poisonings and other consequences of external causes (S00-T98).

  • Foreign body
  • Trauma (injury), unspecified
