title: [A case report of complete inversion of the bladder in an old woman].
abstract: A 77-year-old Japanese woman was admitted to our hospital complaining of small urinary volume. Physical examination revealed a light red, edematous, pyriform mass, approximately 7 cm in diameter at the vulva. An orifice posterior to the base of the mass was catheterized and 20 ml of urine was obtained. Roentgenograms of contrast material injection to the orifice demonstrated a space of 20 ml. A diagnosis of complete inversion of the bladder was made. Under epidural anesthesia, attempts were made to reduce the mass through the urethra. The manual reduction proved to be difficult, but was successful by manual compression of the bladder wall and squeezing it back through the urethra, which took approximately 60 minutes. Complete transurethral inversion of the bladder is so rare that not much of the pathogenesis is clarified. In our patient, senility, obesity, multiple labor and surgeries are assumed to have resulted in laxity of the pelvic wall which would be one of the major risk factors for this condition.
