[Laparoscopic surgery of varicoceles and its effect on testicular hemodynamics and spermiogenesis].

Between December 1993 and October 1996 the authors performed laparoscopic operations of varicocele in 75 patients incl. 53 for concurrent subfertility. In all patients before operation by Doppler sonography and coloured Doppler mapping venous reflux was detected. The volume of the testis was also assessed by sonography. In subfertile patients changes of the spermiogram were assessed. After operation the blood supply was evaluated (the resistive index), the volume of the testes, the duration of the operation and changes in the spermiogram. The authors did not detect a significant difference between the group of 27 patients where with the vein also the artery was ligatured and the group of 48 patients where only the vein was ligatured. The patients were not damaged by ligature of the artery.
