Preliminary study of ultrasound-guided ilioinguinal-iliohypogastric nerve block in performing low ligation of the spermatic vein

Patients in the ILNB group under US guidance were successfully anesthetized according to the requirements for undergoing microscopic low ligation during varicocele surgery. This novel method was proven to be both safe and effective and merits widespread application. US-guided ILNB for low ligation of the spermatic vein was considered "ambulatory surgery". Compared with previous "ambulatory surgeries" under spinal anesthesia, the length of hospital stay was shorter for patients undergoing low ligation of the spermatic vein under ILNB: it was also safe and reliable and more precise, and the cost was lower. In addition to the advantages of significantly lower medical costs, this approach can shorten the hospitalization duration and save medical resources.
