RESUMO
The surgical treatment of undescended and nonpalpable testes still remains controversial. The shorter the vascular stem, the greater difficulties are during orchidopexy. The results of the formerly used "stage" and "Loop" techniques are unsure and frequently lead to postoperative atrophy of the testes. Thanks to the marked development of the microsurgical technique, over the past 10 years, besides the conventional methods for orchidopexy of the testes with a short vascular stem, microvascular revascularization on the autotransplanted testes from the abdomen into the scrotum is also used. During the last year two boys were successfully operated upon with this method with which this microvascular anastomosis technique is described and the problems openly discussed.
