Abstract：Objective To analyze the role of ultrasonography in the diagnosis and postoperative evaluation of cryptorchidism and
cryptorchidism combined with congenital anomalies of the kidney and the urinary tract (CAKUT). Methods A total of 101 children
with suspected cryptorchidism treated in our hospital from July 2019 to May 2021 were selected as the research objects. Physical
examination, laboratory examination, color doppler ultrasonography and laparoscopic exploration were performed. Taking the results
of laparoscopic exploration as the gold standard, the accuracy (accuracy, sensitivity, specificity and misdiagnosis rate) of color doppler
ultrasound in the diagnosis of children cryptorchidism was analyzed. The accuracy of color doppler ultrasound in the diagnosis of
cryptorchidism combined with CAKUT was analyzed based on the results of physical examination, laboratory examination and
other imaging examinations. The children with cryptorchidism were treated with laparoscopic subtesticular fixation. Color doppler
ultrasound was performed at 5 days, 3 months and 6 months after operation. The consistency of preoperative ultrasound diagnosis
of cryptorchidism type, volume and intraoperative findings was compared. The role of ultrasound in evaluating the success rate of
operation and testicular recovery (testicular volume, morphology, blood supply, spermatic cord) at 3 months and 6 months after
operation was explored. Results Totally 83 of 101 children were diagnosed with cryptorchidism. The accuracy, sensitivity, specificity
and misdiagnosis rate of ultrasound diagnosis of cryptorchidism were 97.03%, 98.80%, 88.89% and 11.11%. Among 83 children
with cryptorchidism, 9 cases were diagnosed with cryptorchidism combined with CAKUT. The accuracy, sensitivity, specificity and
misdiagnosis rate of ultrasound diagnosis of cryptorchidism combined with CAKUT were 95.18%, 90.00%, 95.89% and 4.11%.
There was no statistically significant difference between the position and volume of testis diagnosed by ultrasound compared with
intraoperative findings (P>0.05). Totally 83 children underwent surgery, and 80 cases of testis were located in the scrotum without
retraction, the success rate was 96.39%; the rest 3 cases of testis retracted above the scrotum and needed reoperation, the failure
rate was 3.61%. Compared with the recovery of 6 months after operation, there was no significant difference in blood supply andspermatic cord of children with cryptorchidism 3 months after operation (P>0.05), and the normal rate of testicular volume and
testicular morphology was significantly lower, the difference was statistically significant (P<0.05). Conclusion Ultrasound diagnosis
of cryptorchidism is simple and accurate. It can also be used as an early diagnosis tool for cryptorchidism combined with CAKUT. It
can observe the position and development of children’s testis in detail, and has a certain value for postoperative evaluation.
