It is reported that a case of laparoscopic-assisted bilateral testicular descending fixation was successfully performed in Shanghai Children’s Hospital recently. The child was 12 years old and came from Jiaxing. Since birth, the parents found that the child was not only congenitally deaf, but also could not feel his “balls” in his scrotum. With the mindset that he would grow out of it, he was not treated, but as his son grew up day by day, he still could not see his “balls” in his scrotum. The anxious parents visited several hospitals and underwent several ultrasound and CT examinations, but found that only one side of the testicle may exist, and it is still inside the abdominal cavity, while the other side of the testicle has not been explored. Many physicians said that the surgery was very difficult and there was nothing they could do. After many inquiries, the parents brought their child to Shanghai Children’s Hospital. Since the testicles that exist in the abdominal cavity are often stunted, even if they want to preserve them, it is basically impossible to fix them in the scrotum at one time, and it is still unknown whether the other testicle exists, and if an open exploration is done, the surgical incision will be unpredictable. For this reason, the parents came to the newly established “Surgical Treatment Center for Congenital Genitourinary Malformations” in the Department of Urology at Children’s Hospital, full of hope. After careful study, Xie Hua, director of the Department of Urology at Children’s Hospital, decided to use minimally invasive laparoscopic surgery to investigate and decide on further surgical options based on the results of the investigation at the same time. With only a soy-sized incision in the umbilicus and a chopstick-thick mirror, it took a few minutes to find exciting results: both testes were located in the retroperitoneal cavity, and there was hope that both testes, although slightly underdeveloped in shape and size, would be preserved. However, it was then found that the spermatic vessels of both testes were very short, firmly fixing the testes to the posterior abdominal wall, making it impossible for the testes to descend into the scrotum, and since the distance between the testes and the scrotum was 10 cm long, it would be an “impossible task” according to the conventional surgical method. Director Xie Hua made an immediate decision to free and sever the testicular spermatic cord under laparoscopy, while carefully preserving the vas deferens and its surrounding blood vessels to ensure the blood supply to the lateral branches of the testes. The incidence of this bilateral abdominal type of cryptorchidism is not high, and it is often even more rare that the testicular descent and fixation surgery can be completed in one go. Conventional open cryptorchidism exploratory surgery is more blind due to the limitation of visual field and large surgical incision, which makes it more difficult to perform testicular descent and fixation surgery if needed. Currently, laparoscopic techniques have become the method of choice for the diagnosis and treatment of cryptorchidism that cannot be explored. Compared with open surgery, laparoscopy provides rapid and clear localization and characterization during the exploration process and a clear view, and also allows direct or auxiliary operations, which not only minimizes the surgical incision but also makes the surgery smoother.
