Abstract

The definitive goal of orchiopexy is to safeguard spermatogenic potential by relocating the testis to its normal position. Besides the physical relocation of undescended testis to the scrotal position, there are more important parameters than define a successful operation. Since the times when it was first stated that the arterial impedance of a cryptorchid testes possibly has predictive value and provide more precise information about histological changes in the testis, the role of  Doppler studies have acquired dogmatic role in the management of the condition. Herein we further dwelled into the topic and tried to predict the outcome on the Doppler parameters.
