OBJECTIVE To clarify the prevalence and chronological changes of testicular microlithiasis in isolated congenital undescended testes, retrospective chart review was performed.
MATERIALS AND METHODS Among children with palpable isolated undescended testes who underwent orchiopexy at less than 3 years of age between January 2009 and May 2016, those who had preoperative testicular ultrasonography were enrolled. Testicular microlithiasis was classified as limited or classic.
RESULTS Sixty-five patients (54 unilateral undescended testes and 11 bilateral undescended testes) were enrolled. Preoperative evaluation demonstrated limited testicular microlithiasis in only 2 undescended testes in 2 patients (1 with unilateral undescended testes and 1 with bilateral undescended testes). Of these patients, 1 with unilateral undescended testes had limited testicular microlithiasis and the other with bilateral undescended testes had classic testicular microlithiasis after surgery. Among 53 unilateral undescended testes without microlithiasis preoperatively, limited and classic testicular microlithiasis was found in 1 and 6 testes, respectively, during followup. Testicular microlithiasis was identified in 2 on the contralateral descended testis of unilateral undescended testes postoperatively. Among 10 patients with bilateral undescended testes without microlithiasis preoperatively, limited testicular microlithiasis was detected in 4 during follow-up. Testicular microlithiasis was not diminished or resolved during follow-up. The overall prevalence of testicular microlithiasis in undescended testes (21.1%) was significantly higher than that in the contralateral descended testis in patients with unilateral undescended testes (3.7%) (P <.01).
CONCLUSION Most testicular microlithiasis was identified postoperatively and never improved. The prevalence of testicular microlithiasis in isolated congenital undescended testes increased with time even if operated on early in life. 2017 Elsevier Inc.
