Objective   To explore the clinical significance of nonabdominal cryptorchidism treatment under laparoscope.    Methods   Totally 47 patients of nonabdominal cryptorchidism at a mean age of 5.4 years old (ranging from 2 to 12) administrated in our hospital from March

2007 to September

2007 were divided into open-surgery group (23 cases) and laparoscopic surgery group (24 cases) randomly

and orchidopexy was carried out respectively. Operation time

length of stay and testicular volume

hormone level (T

FSH

LH

E

2

) of each patient before operation and 6 months after operation were measured to evaluate the efficacy

.    Results   All 47 patients had orchidopexy carried out successfully. There was no significant difference of operation time between laparoscopic and open-surgery group

but the duration of hospitalization was decreased in the former group. Testicular position was satisfactory 6 months after operation in laparoscopic group

but the volume wasn’t decreased

while T level was increased

and those of FSH and E

2

were decreased than that before operation (P0.05). LH had no significant changes. Testicular volume

level of T

FSH

E

2

and LH had no evident difference between laparoscopic and open-surgery group before and 6 months after operation.    Conclusion   It’s safe and effective to treat nonabdominal cryptorchidism under laparoscope

which may be adapted as routine treatment.
