Transient asynchronous testicular growth in adolescent males with a varicocele.
PURPOSE: We assessed the testicular growth of adolescent males followed nonsurgically for the presence of left varicocele.
MATERIALS AND METHODS: We retrospectively reviewed the charts of adolescent males with a diagnosis of unilateral left varicocele and ultrasound testis volume measurements seen during a 10-year period. A total of 161 boys underwent at least 2 testicular ultrasounds as part of the evaluation for left varicocele. Patients were excluded from study for a history of inguinal/scrotal pathology or endocrinopathy that could affect testicular size. Sonographic testicular volume was calculated using the Lambert volume (length x width x height x 0.71). The resulting volumes were compared to previously published criteria for surgical repair (15%, 20% and 2 cc size differentials).
RESULTS: Of the 71 boys with 3 followup ultrasounds 38 (54%) initially had a 15% or greater volume differential. After nonsurgical followup with ultrasounds for 2 years 60 boys (85%) had testicular volume differentials in the normal range (less than 15%). Of the patients 71% were spared potential surgery by size criteria and 50% were spared surgery by the same 15% volume differential criteria.
CONCLUSIONS: Adolescent males with unilateral left varicocele often demonstrate asynchronous testicular growth that usually equalizes in time. Therefore, sonographic testicular size measurement at a single point during adolescence is insufficient to determine the need for varicocelectomy. When contemplating varicocelectomy we recommend at least 2, and preferably 3, testicular volume measurements 1 year apart to establish accurately decreased left testicular volume compared to a normal right testis.
