[Significance of macroanatomic variants of cavatesticuilar and renotesticular communications in the genesis of right testicular phlebectasia].

The anatomical study of 188 retroperitoneal organocomplexes by direct methods of measurement and nonparametric Spearman correlation analysis explains the significance of different types of right cavatesticular and renotesticular communications in the genesis of expansion of right testicular vein. In 74% of cases, right testicular vein (TV) ends in the inferior vena cava (IVC), and in 26% of cases--in the right renal vein (RRV). When TV ends in IVC, quantity anomaly (doubling TV) is observed in 6.94% of cases; when TV ends in RRV, such anomaly is observed in 40.9% of cases. The width of right TV in the case of its end in IVC was 3.39 ± 0.1 mm, and left TV--2.95 ± 0.1 mm (n = 144), ie, right TV 0.5-1 mm wider than the left TV (P = 0.0008). Correlation analysis showed a weak relationship between the width of the right TV and lack of ostial valve at the end in IVC (r = -0.16, n = 144, P = 0.05). Associations of width of right TV with other factors (lack of ostial valves in the end in RRV, high location of RRV, width of the RRV, angle of return of TV to RRV, deposition of TV entry to the hilum of kidney or IVC) have not been reliably established. The moderate relationship between the width of right TV and type of entry of right inferior segmental renal vein in TV was established (r = 0.63; n = 6; P = 0.05). In a study, among all types of macroanatomical relationships with right TV, a single variant with important role in ectasia of TV was revealed--an entry of inferior segmental renal vein in the retroperitoneal segment of right TV.
