[Clinical Study of Bladder Tamponade at Takeda Hospital].

This retrospective study examined bladder tamponade in 58 patients (male, n＝36 ; female, n＝22 ; average age, 78.5 years old) at Takeda Hospital between 2006 and 2016. Twenty-four of the patients were prescribed anticoagulants, and 18 had an indwelling urethral catheter. The underlying diseases comprised of cystitis (male, n＝7; female, n＝19), iatrogenic lower urinary tract injury (male, n＝13), bladder neoplasms (male, n＝6 ; female, n＝1), prostatic hemorrhage (male, n＝7), renal cell carcinoma (male, n＝1 ; female, n＝1), and bladder stone (male, n＝2 ; female, n＝1). The ratios of cystitis and iatrogenic injury were significantly higher in females and males, respectively (p＜0.0001). Elderly women in particular might be more in need of care due to a tendency towards bladder tamponade. Continuous bladder irrigation and transurethral coagulation were required more frequently for males than females. Radiation cystitis was not the cause of bladder tamponade in any of our patients, indicating that the incidence of bladder tamponade due to radiation cystitis has sharply decreased in Japan over the past 10 years.
