The presence or absence of an impalpable XXXX can be predicted from clinical observations alone.

OBJECTIVE: To evaluate, in a prospective study, the accuracy of predicting the presence or absence of unilateral or bilateral impalpable testes from a clinical examination, particularly whether the @entity717 ( @entity717 ) is hypertrophied. @entity1 AND METHODS: Whether the @entity717 were palpable, and the size of the @entity717 , were determined before surgery in a series of @entity1 , and compared with age-matched controls. Between 1992 and 2000, 100 impalpable testes in 86 consecutive @entity1 (mean age at orchidopexy 45 months, range 6-223; 66% <36 months) were evaluated and treated. In addition to the presence or absence of palpable @entity717 , the size of the @entity717 , when present, and the intraoperative findings were recorded. Logistic regression analysis was used to model the probability of the presence or absence of the @entity1062 , as determined by the preoperative clinical findings alone. RESULTS: Of the 86 testes that were located at surgery, 50 (58%) were intracanalicular, 28 (32%) intra-abdominal and the remainder (10%) were in the superficial inguinal pouch. Of 13 @entity1 with the ' @entity1062 ', the @entity3202 testicle was intracanalicular in nine, in the upper scrotum in three and intra-abdominal in only one. All viable testes were successfully relocated in the scrotum, with one @entity3202 after surgery. The positive predictive value ( @entity2286 , with 95% confidence interval) of a @entity1062 being present when the ipsilateral appendages were palpable and the @entity717 was not hypertrophied was 0.93 (0.83-0.97). Conversely, the @entity2286 of the impalpable @entity1062 being absent when the appendages were impalpable and the @entity717 was hypertrophied was 0.95 (0.64-0.99). CONCLUSION: When evaluating and surgically treating impalpable testes, the presence of palpable @entity717 and a @entity717 with no @entity1184 is associated with a 93% likelihood of discovering a @entity1062 that can be successfully relocated to the scrotum. Conversely, when the @entity717 cannot be palpated and the @entity717 is hypertrophied, there is a 96% probability that the impalpable @entity1062 is absent ( @entity1062 ). This readily available information may be valuable in preoperative counselling and planning.
