Complete Duplication of the Bladder and Prostate with Bifid Urethra but a single Urethral Meatus : A unique case report

Silvia Clauser et al. Urol Case Rep. .

Abstract

The presence of a duplicated urinary bladder and prostate has not been described. We report the case of a complete duplication of the urinary bladder and prostate, associated with one urethral meatus and a bifid urethra. A 68-year-old male presented with chronic lower urinary tract symptoms (LUTS), recurrent urinary tract infections, bladder stone removal and epispadias repair. Bladder duplication was incidentally found during imaging. Cystoscopy confirmed one meatus with two bladders and urethras, each with its own prostate. Transurethral resection of both prostates (TURP) was performed. This is the first reported case of complete duplication of both bladder and prostate.

Keywords: Bladder duplication; Congenital lower urinary tract malformations; Epispadias; Prostate duplication.

Volume-rendered computed tomography (CT) reconstruction (a) reveals a pelvic ring malformation with a widely open pubic symphysis (star). Excretory phase CT (b) demonstrates a horseshoe kidney with dilatation of the left renal pelvis (white arrow) and right ureter (dotted white arrow), alongside a non-dilated left renal pelvis (black arrow) and a normal left ureter (dotted black arrow). In the pelvis, two distinct urinary bladders are visible: the right bladder (white arrowhead) is overdistended and contains non-opacified urine, whereas the left bladder (black arrowhead) appears normally distended and contains contrast-opacified urine.

Axial (a) and coronal (b) T2-weighted Turbo Spin Echo MR images confirm the presence of two distinct urinary bladders (stars) and two separate prostates (arrows), as well as two corpora spongiosa (b, arrowheads). Additionally, two well-defined fluid collections are visible within the suprapubic subcutaneous tissue (a, dotted arrows).
