Management of neonates with large abdominal wall defects and undescended testis.

OBJECTIVES

To assess, in a retrospective study, the outcome of different treatment modalities in newborns with undescended testes secondary to large abdominal wall or diaphragmatic defects. Large abdominal and diaphragmatic defects are known to be associated with cryptorchidism, yet the reported incidence varies widely.

METHODS

A total of 112 neonates with large abdominal wall or diaphragmatic defects were treated from 1981 to 2005. Of the 55 male patients in this series, 9 (16.4%) presented with abdominal testes and 4 had an extra-abdominal testis (7.3%).

RESULTS

The 2 patients undergoing primary orchiopexy had testes of normal size and in the normal position at last follow-up. In one of these patients in whom the testis was brought down to the internal inguinal ring, spontaneous descent occurred and the testis on the affected side was normal. The other patient required additional surgery and had an atrophic testis at last follow-up. In 1 patient with severe concomitant malformations, primary orchiectomy was performed. The 4 patients who did not receive initial treatment all lost their testes owing to atrophy.

CONCLUSIONS

The results of the present study have indicated that primary orchiopexy should be attempted in all cases of abdominal wall defects associated with abdominal cryptorchid testes because it yields better testicular salvage rates. In cases in which the spermatic cord is not long enough to place the testis into the scrotum, mobilization and fixation at the lowest site possible resulted in better outcomes than leaving the testis in the abdomen.
