[Early correction of hypospadias in girl with a disorder of sex development. clinical case].

The presented clinical case of a girl with a salt-wasting form of congenital adrenal hyperplasia in combination with chronic recurrent infection and lower urinary tract dysfunction demonstrates the need to change conventional two-staged approach to surgical feminization in favor of a one-stage intervention in order to prevent a progression of genitourinary complications. After controlling for the underlying condition, the one-stage feminization was performed, including modified tightening introitoplasty using a Passerini-Glazel flap and a correction of hypertrophic clitoris and labia minora. Good short- and long-term results were achieved.

Genes associated with testicular germ cell tumors and testicular dysgenesis in patients with testicular microlithiasis.

Testicular microlithiasis (TM) is one of the symptoms of testicular dysgenesis syndrome (TDS). TM is particularly interesting as an informative marker of testicular germ cell tumors (TGCTs). KIT ligand gene (KITLG), BCL2 antagonist/killer 1 (BAK1), and sprouty RTK signaling antagonist 4 (SPRY4) genes are associated with a high risk of TGCTs, whereas bone morphogenetic protein 7 gene (BMP7), transforming growth factor beta receptor 3 gene (TGFBR3), and homeobox D cluster genes (HOXD) are related to TDS.

[Ultrasonic study in the diagnosis of developmental defects and diseases of the urinary system in children].

Echography has recently become one of the leading methods of examination in different branches of medicine. Despite its high informativeness, however, it is not used widely in pediatrics. The article generalizes the practical experience accumulated in ultrasonic examination of urinary organs in children with developmental anomalies and diseases of the kidneys, ureters, urolithiasis, and Wilms' tumor.
