Final answer:
The 12st step in evaluating severe hypospadius and non-descending testicles is a thorough physical examination. Ultrasound and blood tests are used to diagnose testicular cancer, which has a high cure rate with prompt treatment. Surgery is the standard treatment, sometimes followed by radiation or chemotherapy.
Step-by-step explanation:
The 12st step in evaluating a male patient with a severe case of hypospadius and non-descending testicles, which is also known as cryptorchidism, involves a comprehensive physical examination by a healthcare professional. This physical exam will often include an assessment of the testes, which should normally be approximately 4 to 5 cm in length and descended into the scrotum by birth. When the testes have not descended, it can indicate potential issues, including a higher risk for testicular cancer.
For the diagnosis of testicular cancer, which should be considered if there are symptoms or findings on physical exam that are worrisome, the individual will need further diagnostic tests such as an ultrasound and blood tests for tumor markers. Early diagnosis and treatment are crucial, as testicular cancer has one of the highest cure rates of all cancers. The treatment generally involves surgical removal of the affected testis and potentially additional therapies such as radiation or chemotherapy.
