Magnification-Assisted Subinguinal Varicocelectomy with Testicular Delivery in Children: A Preliminary Report

PURPOSE: To evaluate the effectiveness of magnification-assisted subinguinal varicocelectomy (MASV) with testicular delivery in children with severe varicocele. MATERIALS AND METHODS: We retrospectively analyzed the clinical data of 23 children 15 years or younger (mean age, 12.3±1.8 years) who underwent MASV with testicular delivery and ligation of all collateral veins except arteries and deferential veins between January 2010 and January 2014. All patients had grade 3 varicocele on the left side. Varicocelectomy was decided upon due to scrotal hypotrophy (n=14, 60.9%), the existence of mass (n=6, 26.1%, including 1 recurrent case), and discomfort (n=3, 13.0%). The preservation of internal spermatic artery (ISA) was successful in 8 patients (34.8%). The mean follow-up time was 10.8±6.6 months. RESULTS: The surgical success rate of varicocelectomy was 100%. The overall symptom resolution rate was 91.3%. The scrotal mass and discomfort disappeared, but testicular catch-up growth did not occur in 2 among 14 patients with scrotal hypotrophy. The left testis volume increased from 6.5±4.3 mL to 10.6±7.5 mL (p=0.003). There were no significant inter-group differences in terms of the surgical success rate, symptom resolution, and catch-up growth between the ISA preservation group and the ligation group. None of the subjects demonstrated testicular atrophy or hydrocele after surgery. CONCLUSIONS: MASV with testicular delivery is an effective and safe method for children with severe varicocele.
