Transverse testicular ectopia with persistent Mullerian duct syndrome
The aim of the study was to report on three patients who had transverse testicular ectopia (TTE) with persistent Mullerian duct syndrome (PMDS). Three cases of transverse testicular ectopia and persistent Mullerian duct syndrome were managed at our institution between 2000 and 2009. They presented with right-sided inguinal hernia and left nonpalpable testes. The diagnosis was established during diagnostic laparoscopy. The Mullerian structure was divided in the midline laparoscopically in two patients and by open technique in the third. Good length could be obtained to bring the crossed ectopic testis into the ipsilateral scrotal sac in all cases. Awareness of this anomaly and understanding of the embryological process of testicular descent and its associated aberration are prerequisites for the proper management of this rare anomaly. These findings highlight the importance of diagnostic laparoscopy in all patients presented with nonpalpable testes.
