The patient, a 40-year-old male, was admitted to hospital for "discovering a reversible mass in the left inguinal area for more than 30 years". Married with children. Physical examination: (Standing position) A mass of about 7 cm ×5 cm size can be palpable in the left inguinal area, and it does not fall into the scrotum. (Reclining position) The mass can be taken back by itself, and after being taken back, the fingers touch the outer ring mouth and cough with an impact feeling; The right scrotum is empty, and the left scrotum can reach a single testicle. Previous history of cryptorchidism. Ultrasound of the left inguinal region: hypoechoic in the subcutaneous soft tissue. Ultrasound of male reproductive system showed: testicular echo was seen at the base of penis to the left; Another testicular echo was seen to the left of the scrotum. Enhanced CT of abdomen and pelvis: incomplete left testicular descent; There were no clear testicles and epididymis in the right scrotum (Figure 1). Preliminary diagnosis: left inguinal hernia; Cryptorchidism (crossing the ectopic testis). Intraoperative exploration: The left inner annulus is about 2 cm ×3 cm, and the right testis is located in the left inner annulus (Figure 2A). There is no defect in the right inner annulus (Figure 2B). Pressing the left outer annulus shows that the left testis enters the abdominal cavity through the inner annulus (Figure 2C). The preperitoneal space was freed intraoperatively and the patch was fixed using absorbable nails. The patient visited the urology department before operation and was told that the cryptorchidism may become cancerous. The patient believed that the bilateral testicles were normal in size and strongly requested to preserve the bilateral testicles. During the operation, the urology department consulted that the testicular development of this patient was basically normal and the right cryptorchidism could be preserved. It was recommended that the postoperative urology department performed testicular descent fixation and cryptorchidectomy if necessary.
