The testicles are spherical organs located inside the male scrotum, and are responsible for producing male hormones and sperm. The testicles develop in the abdominal cavity during fetal development, and then descend into the scrotum. A cryptorchidism occurs when the testicles do not reach their normal position during the descent process and remain stationary. A mobile testicle occurs when the testicles move from their normal position due to insufficient fixation, even after descending to the normal position.
For the testicles to function normally, they need to be kept in the scrotum, where the temperature is relatively cool. Undescended testicles and some undescended testicles increase the risk of infertility, testicular torsion, and testicular cancer, so treatment is required.
To accurately diagnose and treat undescended or mobile testicles, regular consultations with a pediatric surgeon or pediatric urologist are necessary.

Since the position of the testicles may not be stable in the early stages of life, the condition is monitored over time, and if a diagnosis is confirmed, surgery is performed between 6 months and around 2 years of age.
The surgery generally involves making an incision of approximately 2 cm in the groin and approximately 1.5 cm in the scrotum, and fixing the testicle in the scrotum, and takes about an hour. However, if the testicle is located within the abdominal cavity or its location is unknown, it is necessary to observe the abdominal cavity using a laparoscope, and in some cases the surgery may need to be divided into two stages. On the other hand, in the case of a mobile testicle, surgery may be possible with an incision in the scrotum only.
At our hospital, we try to accommodate the wishes of our patients as much as possible. Children who do not have underlying conditions such as heart disease or asthma can be admitted as a day hospital.
There are no restrictions on your lifestyle as before surgery. After being discharged from the hospital, you can go to school or kindergarten. Bathing is possible from the second day after surgery. Please refrain from strenuous exercise and swimming for one week after surgery.
Even after the testicles have been fixed to their normal position, they may still rise again or shrink, so patients will be asked to visit the hospital once a year until around puberty for follow-up observation.
