AVOIDANCE OF INGUINAL INCISION IN LAPAROSCOPICALLY CONFIRMED VANISHING TESTIS SYNDROME

Abstract

Purpose: Nonpalpable testicles may be due to the vanishing testis syndrome, intra-abdominal position, examination obscured by obesity or scar tissue and rarely testicular agenesis. Laparoscopy is an excellent means of distinguishing these entities without the need for open abdominal exploration. We investigated whether laparoscopy affects the need for an inguinal incision and exploration when no testicle is palpable and the vas and vas deferens are visualized exiting the internal inguinal ring on laparoscopy.Materials and Methods: In 34 boys 6 to 18 months old (mean age 41) physical examination demonstrated a nonpalpable testicle, including on the right side in 12, on the left side in 17 and bilaterally in 5. The vanishing testis syndrome was diagnosed after laparoscopy when no testicle was palpable despite physical examination done with the patient under anesthesia, spermatic vessels were visualized exiting the internal inguinal ring or spermatic vessels were visualized in the abdomen with or without an ...
