Urogenital system embryology
This document discusses urogenital system development and possible congenital anomalies. It begins by asking questions about anomalies of the kidneys, origins and anomalies of the urinary bladder and urethra, descent of the testes and possible issues, adult derivatives of mesonephric and paramesonephric ducts in males and females, and uterine anomalies. The document is written by Dr. Khaled Elmasry and provides embryological information and explanations to address each question.
