HOW WELL DOES CONTRALATERAL TESTIS HYPERTROPHY PREDICT THE ABSENCE OF THE NONPALPABLE TESTIS?

Abstract

Contralateral testis hypertrophy is common in patients with a nonpalpable testis. Hypertrophy 1.8 cm. or greater predicts monorchia with an accuracy of about 90%. The finding of contralateral testis hypertrophy provides useful information for preoperative counseling, allowing us to inform parents that the nonpalpable testis is most likely absent. Exploration is still required. Laparoscopy is particularly advantageous in contralateral testis hypertrophy since it was the only procedure required in about half of our cases.
