title: Is preoperative laparoscopy useful for impalpable testis?
abstract: OBJECTIVE
  Laparoscopic assessment of pelvic anatomy has gained wide popularity over the years. Today surgical treatment of impalpable testis is nearly always preceded by diagnostic laparoscopy. The actual role of such a procedure remains undefined. We performed a prospective randomized clinical trial in patients with impalpable testis to evaluate the clinical usefulness of laparoscopy before surgical exploration.
  
  
  METHODS
  We studied pediatric, age matched patients with impalpable testis who were randomized to group 1-30 who underwent open surgery only and group 2-31 who underwent laparoscopy and open surgery. Anatomical findings, operative procedures, operative time and cost, number of recurrences and testicular volume at followup were then compared in the 2 groups.
  
  
  RESULTS
  There were no statistically significant differences in the 2 groups for any of the considered parameters except operative cost and time, which were significantly higher in the laparoscopy group.
  
  
  CONCLUSIONS
  Preoperative laparoscopy does not provide any significant advantage over open surgery for treating impalpable testis.
