We present a rare case of mesonephroid adenocarcinoma arising from mesonephroid metaplasia of the urinary bladder. For the first time, the unique histopathologic features in this patient provide evidence for the theory that vesical mesonephroid adenocarcinoma might be a highly aggressive metaplastic variant of urothelial carcinoma that should be treated ...

Postoperative urinary retention following anti-incontinence surgery has traditionally been thought to be due to overcorrection. There is increasing evidence, however, that a neurogenic component may also play a significant role. This is a case report of a 72-year-old woman who developed delayed partial urinary retention following a tension-free vaginal tape ...

We present a case of inguinal bladder hernia detected initially with sonography in an adult patient. Compared with digestive or omental hernias, inguinocrural bladder herniations are a rarer occurrence (1 to 4% of all cases). Their detection is nevertheless highly imperative in order to avoid inadvertent injury to the bladder ...

A case of osseous metaplasia of the ureter presenting as a small upper-ureteral calculus is reported. This rare phenomenon may represent an unusual nucleus for stone formation in the urinary tract. The etiology of this condition is uncertain; we speculate that trauma to the ureter may stimulate osseous metaplasia.

Cavernous hemangiomas are most commonly found within the subcortical neural parenchyma near the fissura Rolandi, in the basal ganglia, or in the brain stem. Because of advancing neuro-imaging technology and thus resulting in a higher incidence of cavernous hemangiomas they have rising impact in neurosurgery. We present two unusual cases ...

A localized arteriovenous malformation of the bladder is extremely rare. To our knowledge, arteriovenous malformation of the bladder has been reported in limited number of cases in the published literature. When arteriovenous malformation is suspected, an angiogram and pelvic computed tomography or magnetic resonance imaging is essential to delineate the ...

Most urethral diverticula are thought to result from infection and obstruction of the paraurethral ducts and glands. When rupture of a resulting retention cyst or abscess occurs into the urethra, a diverticulum is formed. We report two cases of paraurethral abnormalities: urethral diverticulum and paraurethral abscess. Transvaginal sonography, with its ...

The exstrophy variants are uncommon anomalies. The variants of the exstrophy complex have all the stigmata of the classical exstrophy such as divergent recti, widened symphysis pubis, and low-set umbilicus; however, the urinary tract is intact to a varying degree. Pseudoexstrophy, an exstrophy variant, is very rarely associated with epispadias. ...
