Transverse testicular ectopia (TTE) is a rare congenital anomaly where both testes descend through the same inguinal canal and are located on the same side. Cases with fused spermatic cords are particularly rare and present unique surgical challenges.
We report the case of an 8-month-old male infant with bilateral cryptorchidism and an empty scrotum since birth. Preoperative ultrasonography identified two testicular-like structures near the right internal inguinal ring. Laparoscopic exploration revealed bilateral patent processus vaginalis, with both testes located near the right internal inguinal ring. The left spermatic cord crossed the pelvis and fused with the right spermatic cord. Both testes appeared normal in size, with separate epididymides and vas deferens. Surgical management involved careful dissection and separation of the fused spermatic cords, followed by bilateral orchiopexy via the respective inguinal canals and repair of the processus vaginalis. At an 8-year postoperative follow-up, ultrasound confirmed that both testes were well-positioned with normal size and blood supply. Testosterone levels were monitored annually and remained within the normal range. This case highlights its significant role in the management of complex anomalies like TTE.
The postoperative course was uneventful, and an 8-year follow-up demonstrated that both testes remained well-positioned, with normal size, blood supply, and testosterone levels.
睾丸横过异位（TTE）是一种罕见的先天性异常，双侧睾丸通过同一腹股沟管下降并位于同一侧。精索融合的病例尤为罕见，带来了独特的手术挑战。
我们报告一例8个月大男婴，自出生起双侧隐睾，阴囊空虚。术前超声检查在右侧腹股沟内环附近发现两个睾丸样结构。腹腔镜探查显示双侧鞘突未闭，双侧睾丸均位于右侧腹股沟内环附近。左侧精索跨过骨盆并与右侧精索融合。双侧睾丸大小正常，附睾和输精管各自独立。手术处理包括仔细解剖并分离融合的精索，随后通过各自的腹股沟管进行双侧睾丸固定术并修复鞘突。术后8年随访，超声检查证实双侧睾丸位置良好，大小及血供正常。每年监测睾酮水平，均保持在正常范围内。该病例凸显了其在TTE等复杂异常处理中的重要作用。
术后过程顺利，8年随访显示双侧睾丸位置良好，大小、血供及睾酮水平正常。
