INTRODUCTION: Genital ambiguity is a very common phenomenon in disorders of sex development (DSD). According to the Chicago Consensus 2006, feminizing genitoplasty, when indicated, should be performed in the most virilized cases (Prader III to V). Advances in the knowledge of genital anatomy in DSD have enabled the development and improvement of various surgical techniques. Mobilization of the urogenital sinus (MUS), first described by Peña, has become incorporated by most surgeons. However, the proximity of the urethral sphincter prompts concern over urinary incontinence, especially for full mobilization of the urogenital sinus...

Disorders of the ventral tubularization of the urethra, such as the hypospadias, are among the second most frequent congenital childhood malformations. An increasing incidence has been observed suggesting a doubling in the US, which could not be documented for the European area. The underlying causes of this congenital defect remain unidentified. Genetic risk constellations or environmental influences, in particular by so-called endocrine disrupting chemicals (EDCs), are discussed as triggering factors. Boys after in vitro fertilization are more likely to have hypospadias than in nonreproductive-assisted pregnancies...

Down syndrome (DS) is often associated with cardiac malformations, so that kidney damage is little known. The objective of this study was to present the diversity of renal abnormalities and their potential progression to chronic renal failure. Among congenital abnormalities of the kidney and urinary tract (CAKUT) abnormalities appear to be frequent: pyelectasis, megaureters, posterior urethra valves, as well as renal malformations such as renal hypoplasia, horseshoe kidney, or renal ectopia. Contributing factors to acute kidney failure have been described in patients with DS: bilateral lesions and minor renal injury, such as glomerular microcysts, tubular dilation, and immature glomeruli...

Primary malignancies of female urethra are infrequent, constituting a fraction of less than 1% of genitourinary malignancies. Primary clear-cell adenocarcinoma of the urethra, is even rarer, that histomorphologically resembles clear-cell carcinoma of the female genital tract, occurs predominantly in women and is associated with a relatively poor prognosis. The histogenesis of this rare urethral neoplasm has not been completely determined. Various hypotheses concerning the origin have been postulated, including (1) diverticular origin (2) mullerian origin (3), glandular differentiation of urothelium or urothelial carcinoma...

We isolated a cryptic genospecies of Haemophilus influenzae referred to as 'Haemophilus quentini' in the urethra of 3 men complaining of urethritis symptoms. H. influenzae strains, which had been isolated from the urethra in 77 of 1518 men complaining of urethritis symptoms, identified by the conventional test, and stored, were re-cultured for this study. Sixty-seven strains surviving storage were screened by a PCR-based assay specific for the cryptic genital Haemophilus genospecies. Three strains (HI09003, HI11006, and HI14016) were screened by PCR and identified as 'H...

Adenocarcinoma of Skene's gland (the female homolog to the male prostate) is extremely rare, with only a few cases reported. We present a case of Skene's gland adenocarcinoma with intestinal differentiation. The patient was a 69-year-old Japanese woman who was operated on for a recurrent tumor of the external ostium of the urethra. Histopathologically, the tumor showed glandular and cribriform patterns with a signet-ring cell component in a mucus lake. Immunohistochemically, the tumor cells were positive for prostate specific acid phosphatase (PSAP), and AMACR, and negative for Nkx3...
