We report two cases of symptomatic prostatic cysts, which were arising around the bladder neck, in a 39-year-old man without clinical evidence of benign prostatic hyperplasia and a 72-year-old man with refractory bladder outlet obstruction. The lesions were found by abdominal ultrasound examination for post-voiding residual at the first visit. Transurethral unroofing of the cysts was performed with successful resolution of voiding symptoms.
