[Personal experience with peroperative study of testicular blood flow in laparoscopic surgery of varicocele].

Although the authors did not detect in 27 patients operated since October 1996 laparoscopically for varicocele, although the spermatic artery was ligatured a deteriorated blood supply of the testis, they evaluated the blood flow through the spermatic artery in the rete testis by coloured Doppler mapping during temporary peroperative ligature of the spermatic artery. In 14 patients the occlusion did not cause any changes of the blood supply of the testis, in one patient during occlusion of the artery the Doppler signal in the rete testis disappeared, after release of the ligature the blood flow reappeared in the coloured Doppler mapping. The authors conclude that in the great majority of men the blood supply of the testis is ensured by collateral circulation. If the ligature of the spermatic artery is inevitable they recommend to check during operation the blood supply of the testis in the rete testis by dopplerometry.
