[Undescended testicles: 2-stage reduction or Fowler's technic. Apropos of 2 comparative series].

The testicular vessel transection allows a one-stage orchidopexy for high undescended testes. The authors have been using this procedure (as described by Fowler) since january 1984. 29 operations have been performed in this way. This series is compared to another series of 28 staged orchidopexies, a procedure which was used in Rouen until december 1983. The number of cases in each series is not high enough to allow a significant comparison; no conclusion can be drawn as for the long term result concerning the testicular function. However the procedure described by Fowler has the great advantage of being performed in one-stage. But the surgeon must comply with strict rules and the authors point out the difficulties of the operation.
