The field of underactive bladder is a poorly recognised yet important clinical condition, affecting up to a third of patients over 65. In this book, the authors look at the field of underactive bladder and its presentation, clinical diagnosis, potential etiopathogenesis and treatment. While the editors address a great deal of background information, they clearly identify that many limitations still exist to clinical diagnosis and urodynamic evaluation, and in particular a dearth of appropriate treatment options. This complex condition needs to be recognized and identified in the routine evaluation and clinical management of patients. von Chapple, Christopher R. und Wein, Alan und Osman, Nadir I.
