“…Of the above urologic anomalies, most are relatively asymptomatic and do not require surgical reconstruction. However, patients who are incontinent, who have recurrent urinary infections, lower or upper urinary tract obstruction, or voiding dysfunction such as double urinary streams usually merit urologic repair [1][2][3][4][5][6][7][8][9][10][11][12][13].…”

We report a rare case of duplication of the bladder, urethra, uterus, vagina, and associated anomalies in a woman. As an infant, she initially underwent successful surgical reconstruction. As an adult, she developed adenocarcinoma within the defunctionalized bladder moiety. The surgical management and pathology of this cancer are detailed and the pertinent literature reviewed. J. Surg. Oncol 1997;65:280–283. © 1997 Wiley‐Liss, Inc.

“…Complete duplication of the bladder is rare, with <50 cases previously reported in the world literature [1][2][3][4][5][6][7][8][9][10][11][12][13]. We report here the first case of adenocarcinoma arising in a duplicated bladder.…”

“…Rarely, there may be a single urethra leading to outlet obstruction of one of the bladders. [78] Urethral duplication commonly occurs in the sagittal plane, though rare cases of duplication in the coronal plane have also been reported. [9] Duplication of the urethra could be partial [Figure 5] or complete [Figure 6] and either hypospadiac or epispadiac [Figure 7], depending on the relation of the accessory channel with the orthotopic urethra.…”

Congenital anomalies of the male urogenital tract are common. Some lesions like posterior urethral valve or anterior urethral diverticulum tend to present early in infancy and are often easily diagnosed on conventional contrast voiding cystourethrograms. Other conditions like posterior urethral diverticulum or utricle can be relatively asymptomatic and therefore present late in childhood. We present the spectrum of imaging findings of common and uncommon anomalies involving the male urethra. Since the pediatric radiologist is often the first to make the diagnosis, he or she should be well aware of these conditions.

“…Abrahamson (49) offered two explanations: (a) excessive constriction between the urogenital and vesicourethral portions of the ventral cloaca, and (b) a supernumerary cloacal septum that indents the epithelial wall of the bladder. In some cases, only one bladder communicates with a single urethra, leaving the opposite side obstructed with no outlet (51,52). The primitive hindgut is the anlage of the terminal ileum, colon, and cloaca.…”

Congenital anomalies of the lower urinary tract are a significant cause of morbidity in infancy. Radiologic investigation is an important source of clinical information in lower urinary tract disorders but should not inconvenience the patient, expose the patient to unnecessary radiation, or delay surgical correction. In pediatric patients with suspected underlying urologic structural anomalies, screening ultrasonography is commonly the initial diagnostic study. If dilatation of the urinary tract is confirmed, voiding cystourethrography is performed to determine the presence of vesicoureteral reflux (VUR) and other causes of upper tract dilatation. If VUR is confirmed, follow-up with nuclear cystography or echo-enhanced cystosonography may be performed. If VUR is excluded, nuclear diuresis renography is the primary test for differentiating between obstructed and nonobstructed megaureter. Intravenous urography can be used to specifically identify an area of obstruction and to determine the presence of duplex collecting systems and a ureterocele. Computed tomography and magnetic resonance (MR) imaging are unsuitable for general screening but provide superb anatomic detail and added diagnostic specificity. MR imaging is mandatory in the evaluation of associated spinal anomalies. MR urography can demonstrate ectopic extravesical ureteric insertions, thereby providing a global view of the malformation. Familiarity with anomalies of the lower urinary tract is essential for correct diagnosis and appropriate management.
