WHAT'S KNOWN ON THIS SUBJECT:Primary care providers (PCPs) identify patients with undescended testis (UDT) and refer them to surgical specialists. Referral beyond the recommended times for orchiopexy has been reported, and PCPs' accuracy in identifying and distinguishing UDTs from retractile testes has been questioned.
WHAT THIS STUDY ADDS:We describe 3 observations that are strongly correlated with UDT, that is, birth history of UDT, prematurity, and visible scrotal asymmetry. UDT diagnoses are best made by 8 months of age, to reduce confusion with testicular retraction and to facilitate timely orchiopexy.abstract OBJECTIVES: The goals were to determine current referral patterns for boys suspected of having undescended testis (UDT) and to identify factors to assist primary care providers in distinguishing retractile testes from UDTs on the basis of history, physical examination, or imaging findings.
METHODS:By using a standardized history assessment, visual inspection of the scrotum for symmetry, physical examination, and review of previously obtained imaging findings, we performed a prospective observational study with consecutive patients referred to a pediatric urologist for evaluation of UDT.
RESULTS:Of 118 boys, 51 (43%) had descended testes, 60 (51%) had UDTs, and 7 (6%) had initially indeterminate findings. Boys with UDT were referred at a median age of 43.3 months. Patients referred at Ͻ1 year or Ͼ10 years of age were significantly more likely to have UDT than were those referred at 1 to 10 years of age. History of UDT at birth, prematurity, and scrotal asymmetry strongly increased the risk of UDT. Genital ultrasonography had been performed for 25% of patients, incorrectly indicating UDT for 48%.
CONCLUSIONS:Most boys were referred well beyond the recommended age of Ͻ12 months for orchiopexy. Only one-half of the patients had UDT, with most errors in diagnosis being made for boys 1 to 10 years of age, which suggests difficulty distinguishing UDT from retractile testis. Positive birth history findings, prematurity, and scrotal asymmetry predicted UDT and can be used by primary care physicians in their assessment before referral. Genital ultrasonography did not distinguish UDTs from retractile testes. Pediatrics 2011;127:e382-e388 AUTHORS:
