title: Pseudomass of the bladder neck after prostatectomy: report of two cases.
abstract: The authors reviewed ultrasonographic (US) images, cystoscopic findings, and biopsy results at the vesicourethral anastomosis in two patients suspected of having local recurrence after radical prostatectomy. A focal, masslike bulge was identified with US at the posterior aspect of the bladder neck, just above the anastomosis. This bulge mimicked the appearance of local recurrence of cancer; however, diagnostic studies, biopsy results, and clinical follow-up failed to demonstrate recurrent cancer. A review of the surgical technique led the authors to conclude that a pseudomass at the vesicourethral anastomosis may result from focal infolding of normal bladder mucosa.
