Undescended testis
The testis develops primarily inside the abdomen. It comes down to the scrotum by birth. The way down to the scrotum is through the inguinal canal. This canal starts from the abdomen by the so called internal opening (internal ring) and ends by the so called external opening (external ring). The testis may stay at any position during its journey of coming down from the neighborhood of the kidney to its final position. This is called undescended testis. This may be due to a short artery of the testicle or due to a short band (gabernaculum) which fixes the testis to the bottom of the scrotum. A short spermatic string (spermatic cord) may be also responsible for the retention of the testis. The testis may be abdominal, inguinal or even a Penndel testis. Penndel testis means that the testis is wandering between the scrotum and any station upwards. It is important for the testis to stay permanently or even mostly inside the scrotum. The testis must enjoy a temperature of 1-1,5 C° lower than the temperature of the body to be able to function and not to develop cancer. Undescended testis wheatherr inguinal or Penndel testis is subject also to trauma.

Children who are older than one year and who have their testis most of the time upwards as an undescended testis. The child is put under general anesthesia on his back. The incision is done in the inguinal region. The testis is delivered outside. The artery, vein and the spermatic string are prepared free and followed as far as their length allows to put the testis to the lowest point of the scrotum. The testis should be fixed without any tension. The peritoneum may be pushed away to reach these structures and free them generously. The skin of the scrotum is put under tension. A sac is prepared between the skin and the subcutaneous tissues large enough to let the testis be inserted inside it. The testis is pulled with sutures inside this sac without any tension and fixed there. The wounds are closed in layers. A bandage is applied.
