Thirty-nine   male  patients, 19  to 49 years  old with varicoceles, were referredfrom the infertility   clinic  of  Dermatology  &  Venereology Department in Sohag  University  Hospital.  All presented   for   primary   infertility  (at  least 1 year duration).  The  diagnosis   was  confirmed by  ultrasonography    and   Colour   Flow  Doppler. The patients  underwent  varicocelectomy. The  operative   treatment   of  varicocele   has  a definite place  in the treatment  of some subfertile  men. Conventional techniques   of  varicocele  operations   are  associated   with  substantial   risk   of  hydrocele  formation.   Analysis   of the protein   concentrations    of  hydrocele  fluid indicates  that  hydrocele  formation   after  vari- cocelectomy   is due  to  lymphatic   obstruction. Visualization   and  identification   of  lymphatics accompanying    testicular   vessels   to  preserve them  can eliminate  the development   of hydrocele  after  varicocelectomy.     We described   our experience   with a new  technique  of varicocelectorny  that significantly   lowers  the incidence of postoperative   hydrocele.   We visualized   lymphatics  using  the  traditional   visual  lymphangiogram  to colour  the lymphatics  accompanying   the   testicular  vessels.    Dissection  and ligation  of the testicular  veins away from  the visualized   lymphatics   was done.   Preservation of lymphatics   prevents  the occurrence  of postoperative  hydrocele.     Our technique  is easy  to do,  and  minimally   invasive. No complications were  recorded   after  this  technique.   The  improvement   in semen parameters   after  varicocelectomy  using  this   technique, either  by high ligation or subinguinal approach, were  very satisfactory and statistically  highly  significant
