Brief summary

This prospective interventional study aimed at the preoperative sonographic estimation of the testicular volume of the normal side in case of contralateral impalpable maldescended testis in order to predict the condition of the diseased side and hence the need for diagnostic laparoscopy.

Detailed description

Purpose: This study aimed at the evaluation of the value of the estimated volume of a normal testis to predict the status of its contralateral impalpable side and hence decide the importance of laparoscopic exploration. Material & methods: Patients with unilateral impalpable maldescended testis - as confirmed by clinical and sonographic examination- were enrolled in this prospective interventional study between November 2018 and August 2022 at Elshatby University Hospital, Faculty of Medicine, Alexandria University. The volume and three-dimensional diameter of the normal contralateral testis were measured by the pre-operative US using the formula: Volume = L x W x H x π/6, where L is the length, W is the width, H is the height, and was correlated with the intra-operative laparoscopic findings.
