Cystourethrograms characteristic of bladder instability are illustrated. A repeated increase of intravesical pressure causes functional and morphologic deformities of vesicourethral configuration: ballooning of the proximal urethra, ureteric reflux, and trabeculated bladder during the storage phase; and dilatation of bladder neck and proximal urethra, and a pearl string-like configuration of urethra during the voiding phase. The clinical significance of these observations is presented.
文中展示了膀胱不稳定特征的膀胱尿道造影。膀胱内压反复升高会导致膀胱尿道结构出现功能和形态学畸形：在储尿期，近端尿道球囊样扩张、输尿管反流以及膀胱小梁形成；在排尿期，膀胱颈和近端尿道扩张，尿道呈珍珠串样形态。本文还阐述了这些观察结果的临床意义。
