“…The incidence of cryptorchidism among full-term newborns ranges from 1.0 to 4.6% at the time of birth [1]. Palpable forms of cryptorchidism are present in 73 to 90% of affected boys, while the testicle resides in a nonpalpable position in 10 to 27% of patients [2][3][4][5][6][7]. In half of the patients suffering from nonpalpable cryptorchid testes, the testes are located intraabdominally.…”

Abdominal Cryptorchidism with Complete Dissociation between the Testis and Deferent Duct Mimicking Testicular Regression Syndrome

Complete separation of the deferent duct from the epididymis in cryptorchid testes residing in the abdomen is an extremely rare variant of developmental disorders of the testis and epididymis. Available sources mention only three clinical cases similar to our observations. The unique anatomic aspects of this disorder hamper the correct diagnosis of an intra-abdominal cryptorchid testis. Two boys with nonpalpable left-sided cryptorchidism underwent diagnostic laparoscopy, revealing an intra-abdominally located testis. The epididymis was completely separated from the deferent duct, and the epididymis and testis were supplied by testicular vessels. Exploration of the inguinal canal revealed blind-ending deferent ducts. The testis was brought down through the inguinal canal and fixed in the scrotum in both boys. The follow-up examination at 6 months revealed no signs of testicular atrophy or malposition of the testis in either patient. With our observations in mind, the exclusive use of a transscrotal or transinguinal approach as the initial surgical exploration in the treatment of patients with nonpalpable forms of cryptorchidism may be inappropriate. Careful laparoscopic examination of the abdominal cavity is indispensable in children with suspected testicular regression syndrome or nonpalpable forms of cryptorchidism.

Introduction. Complete separation of the deferent duct from the epididymis with the testicle in abdominal cryptorchidism cases is an extremely rare variation of abnormal development of genitals in boys. Available sources mention just 3 clinical cases similar to our observations. The unique anatomic details of the abnormality and extreme rarity of its exposure pave the way for a failure to reveal an intra-abdominal testis, and determine the need for particular attention during diagnostic laparoscopy. Materials and methods. Two patients with non-palpable left-sided cryptorchidism underwent a diagnostic laparoscopy, which revealed an intra-abdominal testis with epididymis on testicular vessels that was completely separated from the deferent duct. The difference between the described clinical cases was in the distance between the deep inguinal ring and the crossing of testicular vessels from the retroperitoneal location to the intraperitoneal position, which was approximately 3- 4 cm in the first patient and 4-5 mm in the second one. The second difference was in the "closed" deep inguinal ring found on the left side in the first case while the second patient had a patent processus vaginalis case. In both cases an incision was made in the left inguinal area, the inguinal canal was opened, and exploration thereof revealed blind-ended deferent ducts. The testicle in both cases was brought down through the inguinal canal and attached in the scrotum. Results. No complications occurred during the early postoperative care period, the check-up examination in 6 months following the surgery revealed no signs of testis atrophy or malposition in both patients. Conclusion. In diagnostic laparoscopy for abdominal cryptorchidism, it is important to consider the possibility of complete separation of the testicle and vas deferens. Detection of the deferent duct passing through the «closed» deep inguinal ring together with hypoplastic vessels does not rule out the chances for an ipsolateral intra-abdominal testis; therefore, a careful examination of the abdominal cavity along the embryological testicular migration path is necessary.
