Abstract
Inguinal hernia and hydrocele affect the blood circulation of the testicle. Surgical trauma may change testicular blood flow.
Objective. To study changes in blood flow parameters in children with pathology of the processus vaginalis,
requiring surgical correction, using the analysis of ultrasound data.
Materials and methods. We observed 87 boys from 3 to 17 years old, operated for congenital inguinal
hernia and hydrocele. As a control group we examined 34 boys without pathology of the reproductive system.
Patients held Doppler ultrasound the day before surgery, at 1 and 7 days after. Peak systolic flow velocity,
end-diastolic flow velocity and resistance index were studied.
Results. The resistance index on the affected side was higher compared with the control group before
operation (p<0,05). The values of peak systolic and end diastolic blood flow velocities were lower than in the
comparison group (p<0,05). Resistance index increased compared with preoperative period 1 day after surgery
(p<0,05). Values of flow velocity parameters decreased to 4-9 % compared to values before the operation.
The resistance index decreased (p<0,05) to near baseline figures a week after the operation. Peak systolic and
end-diastolic flow velocity raised to 15-21 % compared to the preoperative period. However, the intensity of
the blood flow in the affected testicle remained lower than in the control group (p<0,05).
Conclusions. The blood flow of affected testicle in children with inguinal hernia and hydrocele is initially
decreased. Early postoperative period is characterized by intensification of testicular parenchyma’s ischemia.
Postoperative blood flow in the affected testicle is improved a week after surgery, but the lack of blood supply
to the testicle is retained
