The common reasons for the recurrence of varicocele are primary factors not dealt with, comorbidities not dealt with, surgical omission of ligature and so on, details are as follows. 1. Primary factors are not dealt with: varicocele is divided into primary and secondary, if only secondary symptoms are dealt with during surgery, primary factors are not lifted, and recurrent attacks can occur. 2. Combination not dealt with: if the combination of the introductory vein, vasovaginal varicose veins, and the operation only ligation of the internal veins of the spermatic cord, vasovaginal veins and the introductory veins, and even the thick veins of the levator ani muscle are not dealt with, it will lead to recurrence of the symptom. 3. Surgical omission of ligation: the internal spermatic veins above the internal inguinal ring often converge into 1~3 branches, or may converge into 4~5 branches, or even more. Some of these varicose veins are not obvious, and the stimulation of the operation can cause vascular spasm and thinning, thus resulting in the operation of the missed ligation, is also an important reason for the recurrence of the operation. Once the recurrence of varicocele occurs, it must cause enough attention, and it is recommended that the patient go to the regular hospital for consultation, and give targeted treatment after the doctor clarifies the cause.
