Non-Invasive Management of Varicocele-Related Scrotal Pain Using Transcutaneous Neuromuscular Electrical Stimulation

To begin, instruct the patient to sit still or lie flat on the procedure bed for 15 minutes. After the patient enters the examination compartment, ask the patient to follow the system voice instructions for movements. Click on Freeze to save the image.

Then, move the mouse to the testicles in the patient's action screen and observe the abnormal body temperature region. Subtract the temperature of the healthy testis from the temperature of the affected testis to obtain the bilateral scrotal temperature difference. Apply electrode pads to the patient's abdomen and bilateral inguinal regions.

Adjust the current intensity and pulse width on the electrode pads to levels acceptable to the patient, and set the current intensity to four hertz, followed by the pulse width to 400 microseconds. Record the current intensity and pulse width at which the area of temperature abnormality on the scanner returns to normal. Then, locate the treatment protocol in the system that corresponds to the recorded current intensity and pulse width.

Finally, input the treatment protocol into the removable low-frequency neuromuscular therapy device. Guide the patient through the treatment, selecting appropriate parameters within a frequency range of 1 to 400 hertz and a pulse width of 50 to 1, 000 microseconds. The mean visual analog scale score, bilateral scrotal temperature difference, internal diameter of the spermatic vein, and blood reflux time in the spermatic vein significantly decreased after treatment.

The testicular atrophy index showed no statistically significant change, remaining approximately the same before and after treatment.
