Introduction Primary female bladder neck obstruction is a rare clinical condition characterized by the absence/incomplete bladder neck opening during the voiding phase of micturition. Methods We present the cases of two women complaining dysuria, abdominal straining and sensation of incomplete bladder emptying. Videourodynamic evaluation was fundamental for a correct diagnosis. Results Videourodynamic evaluation showed a high detrusor pressure during emptying phase, partial use of abdominal strain, very low urine flow rate and significant postvoid residual; imaging showed a defect in the physiological funneling of the bladder neck, absent or incomplete. The first step therapy is represented by oral alpha-blockers and clean intermittent self-catheterization in case of high postvoid residual. Surgical operations, such as bladder neck incision and resection, represent the last option. Conclusions In our experience, bladder neck obstruction is a rare condition in women and only a complete clinical evaluation associated with videourodynamic study can lead to an appropriate diagnosis and treatment.
