Clinical Observation of Varicocele Using a Phlebography / 대한비뇨기과학회지

ABSTRACT

Varicocele is a abnormal dilation of entire venous circulation of testis. The etiology of varicocele subfertility is not clear, but at least contributory to its development is a valvular insufficiency at the internal spermatic-left renal vein confluence. The aims of phlebography of the spermatic vein are to confirm the venous anatomy of varicocele, to establish the selection of treatment approach, and to prove the cause of postoperatively persistent varicocele. The transfemoral phlebography of internal spermatic vein was performed in 26 cases. passive reflux from the left renal vein to internal spermatic vein was observed in all cases. Distal nutcracker phenomenon(DNP) was observed in 6 cases, proximal nutcracker phenomenon(PNP) in 4 cases and suspicious PNP in 2 cases. The treatment of the varicocele was performed by Palomo`s procedure in 22 cases and by stainless steel spring coil occlusion in 4 cases. The persistent varicocele was found in 3 cases of Palomo`s procedure and 1 cases of coil occlusion.
