OBJECTIVES: @entity1184 has previously been evaluated as a predictor of monorchism. However, its implication in clinical practice is not well evaluated. The aim of the present study was to examine its value in planning the operative time. @entity1 AND METHODS: Medical charts of prospectively recorded data of 76 consecutive @entity1 with unilateral impalpable testis from 2011 to 2014 were reviewed at the present institute. Inclusion criteria included prepubertal @entity1 with non-palpable @entity1062 by examination under anesthesia. Contralateral @entity1062 were prospectively measured using a Takihara orchidometer. Orchiectomy or orchiopexy was performed according to the viability of the @entity246 ( @entity246 ). Collected data included age of surgery, contralateral testicular size, surgical time and laparoscopic findings. A ROC curve was used to define the best cut-off volume of the contralateral testis that can predict ipsilateral testicular viability. The Student's t-test was used to examine if this cut-off volume would be useful in allocating the operative time. RESULTS: Of 76 @entity1 , four palpable @entity1062 by examination under anesthesia were excluded. The remaining 72 @entity1 were included in the study. Ipsilateral normal viable @entity1062 were found in 26 (36.1%) @entity1 , while 46 (63.9%) had non-viable @entity1062 (testicular nubbins or vanishing @entity1062 ) (Figure). A contralateral testicular volume > 2 ml was significantly predictive for monorchism with 71.7% sensitivity and 100% specificity (P < 0.001). The mean operative time for management of @entity246 with a contralateral size >2 ml was 50 min, which was significantly shorter than that for @entity246 with a contralateral size  <= 2 ml, which was 88 min (P < 0.001). DISCUSSION: In previously published reports, the cut-off value for @entity1184 that predicts monorchism greatly varied. This is likely due to the different methods used for testicular measurements that make it impractical to make a direct comparison. The usefulness of predicting monorchism before surgery has not previously been used as a guide for allocating operative time in the management of a unilateral non-palpable testicle. This study had some limitations, including a relatively small sample size and involvement of different surgeons, which may have affected the operative time. CONCLUSION: Using the cut-off volume of a contralateral testis >2 ml as a predictor for monorchism can reduce the allocated operative time by approximately one third.
