Duplication of Urethra - Case Report and Review of Literature

Abstract

Duplication of urethra is very rare. The duplicated urethra is always dorsal to the normal urethra which contains the sphincteric mechanism. A case is reported of urethral duplication where the duplicated urethra presented as a sinus on the dorsum of the penis.

A new case of male Y-type urethral duplication and review of literature

“…Approximately 300 cases of urethral duplication have been reported [1][2][3][4][5][6][7][8][9][10][11][12], the most extensive series were published by Senocak [13] and Salle et al [4]. Most urethral duplications are dorsal-ventral and occur in the sagittal plane [1,2].…”

“…So far, less than 300 cases have been reported in the literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Several types of anatomic variations have been identified with the second urethra being epispadiac, in normal position, or hypospadiac.…”

Excision of a symptomatic unusual duplicated urethra in an adult male

“…The first principle is recognition of the native urethra, identified by the presence of a normal verumontanum, distal urethral sphincter and its generally wider calibre. 3,4 Prior to proceeding with surgery, it is important to ensure that the native urethral calibre is sufficient to allow unobstructed urine flow. The accessory urethra can then usually be adequately excised with concomitant correction of any chordee or epispadias/hypospadias.…”

A urethral duplication cyst complicated by a squamous cell carcinoma

“…Duplication of the urethra is very rare [ 1]; it has been described in both males and females, either in isolation or in association with other congenital anomalies. Various complications have been described including recurrent UTIs [ 2], post‐micturition dribbling and obstructive uropathy [ 3].…”
