Validated Assessment of Ejaculatory and Erectile Function After Unilateral “Z”-Shaped Bladder Neck Incision (ZANCLE): A Prospective Study Using the MSHQ-EjD Short Form and IIEF-5

Background/Objectives: Preservation of anterograde ejaculation after transurethral incision for primary bladder neck obstruction (PBNO) has traditionally been assessed with unvalidated binary self-report. We prospectively evaluated ejaculatory and erectile function after the ZANCLE (“Z” Anatomical Needle Cut Leads Ejaculation) technique using two validated patient-reported outcome instruments, the Male Sexual Health Questionnaire–Ejaculatory Dysfunction Short Form (MSHQ-EjD-SF) and the International Index of Erectile Function-5 (IIEF-5).
