Treatment and prognosis of children with torsion of inguinal cryptorchidism / 中华泌尿外科杂志

ABSTRACT

Objective:To discuss the treatment and prognosis of children with torsion of inguinal cryptorchidism.Methods:Clinical data of 15 cases of inguinal cryptorchidism with testicular torsion admitted to Beijing Children's Hospital from October 2015 to February 2019 were retrospectively analyzed. The average age of onset was 5.1 years (4 months-17 years). The clinical manifestations included inguinal swelling and pain in 13 cases, abdominal pain in 1 case and abdominal pain with vomiting in 1 case. The average duration of symptoms (up to the time of surgery) was 45.9 (5-170) h. Physical examination showed scrotal voided on affected side, groin swelling with tenderness. Lesions were found in 12 cases on the left and 3 cases on the right. Groin color Doppler ultrasound examination showed testis enlargement, uneven echo, decrease or disappearance of blood flow signal, suspected testicular torsion. Clinical diagnosis was inguinal cryptorchidism testicular torsion. Inguinal canal testicular exploration under general anesthesia. During the operation, the testicle was dark and twisted with an average torsion of 600°(180°-1 080°). Testicular activity was observed after exposure and reduction and torsion. After reduction, testicular color was immediately restored in 5 cases. After cutting open the white membrane of the testicular, there was blood outflow. In 2 cases, the testis was found to be inactive during the operation, but the parents requested to retain the testis and performed orchiopexy. 8 cases underwent orchiectomy due to necrosis of testis. The mean symptom duration (up to the time of operation) of the orchiectomy group and the orchiectomy group was 24.3 (5-73) h and 64.8 (7-170) h, respectively. The average torsion degree was 514° and 675°, respectively.Results:The average operative time of 15 patients was 56.7 min (40-85 min). Intraoperative blood loss averaged 1.5 (1-2) ml. There were no complications during and after operation. Postoperative follow-up averaged 27 (8-47) months. Among the 7 patients in the orchiopexy group, 3 patients had atrophy of testis 7.3 months after operation, and the remaining 4 patients had normal testis. In the orchiectomy group, 8 cases had normal contralateral testis without torsion.Conclusions:Inguinal cryptorchidism testicular torsion is a relatively rare disease in children. Color Doppler ultrasonography and inguinal canal exploration can help diagnosis and treatment. According to the condition of testis, orchiopexy or orchiectomy can be performed. Early diagnosis of this disease is difficult, easy to lead to testicular loss or postoperative atrophy.
