Unilateral cryptorchidism in a 7-year-old boy is mainly treated by surgery; clinically, testicular surgery is divided into two types: testicular restoration and fixation and orchiectomy, which should be chosen according to the specific conditions of the patient.
1. Testicular reset and fixation: if the patient is sure that the testicle is located below the inguinal area after physical examination or ultrasound, testicular reset and fixation can be used for treatment, and the function of the testicle on that side can be preserved under normal circumstances.
2. Orchiectomy: If after ultrasound examination, it is determined that the testicle on the diseased side stays in the abdominal cavity, which may have lost its function, then orchiectomy is needed to treat it and reduce the possibility of malignant transformation of the testicle.
Unilateral cryptorchidism in a 7-year-old boy needs timely medical attention and active treatment under the guidance of a professional doctor.
