Bladder tamponade is thought to be caused mainly by bladder cancer or radiation cystitis. However, in women, it may often be caused by cystitis in clinical settings. This has not been noted in previous reports of bladder tamponade in Japan. Thus, we retrospectively analyzed the clinical features of 83 male and 41 female patients with bladder tamponade. Seventy-four patients were treated at Nishi-Kobe Medical Center between April 2005 and March 2015, and 50 were treated at Shizuoka City Shizuoka Hospital between November 2008 and March 2015. The patients'median age was 80 years. The cause of bladder tamponade was urological malignancies in 33 of the 83 male patients (40%), benign prostatic hyperplasia in 20 of the 83 male patients (24%), and cystitis in 33 of the 41 female patients (80%). Compared with the men, the women with bladder tamponade were significantly older and the proportion of patients with cerebrovascular disease, diabetes, and dementia was higher. In addition, more women were nursing home residents, with a higher rate of voiding with diapers and antithrombotic use than men. Causative strains of cystitis were diverse, and some were antibiotic resistant. Most of the cases of bladder tamponade in the women occurred in the elderly and were caused by cystitis. In an aging society, increases in the incidences of chronic, complicated cystitis due to impaired independent micturition, dysuria, and systemic diseases such as diabetes, and increased use of antithrombotic drugs may contribute to bladder tamponade in women.
