Association between left-sided varicocele and epididymo-orchitis with sonographic findings

Abstract

Objective: The aim of this study was to investigate the relationship between left-sided varicocele and epididymitis or epididymo-orchitis. Materials and Methods: The study included 72 patients with left side epididymitis (EP) or epididymo-orchitis (EPO) (Group 1) and a control group of 72 patients without EP or EPO (Group 2). Those with right EP-EPO were excluded due to possible other underlying retroperitoneal pathologies causing varicocele. Groups were evaluated for presence of left side varicocele, varicocele grade and pampiniform plexus vein diameter. Results: The average age was 38 +/- 8.4 years (range, 18-50 years) in Group 1, and 36 +/- 9.1 years (range, 16-47 years) in Group 2. Varicocele was significantly more common in patients with EP or EPO (p < .001). The rate of varicocele was 66.7% (48/72) in Group 1, and 22.3% (16/72) in Group 2. The median grade of varicocele was 2 in Group 1, and 0 in Group 2. Pampiniform plexus vein diameters were found to be significantly larger in patients with EP or EPO compare to patients without EP and EPO. The median vein diameter was 3.3 mm with the 25th and 75th percentiles at 2.7 and 3.8 mm, and was 1.9 mm with the 25th and 75th percentiles at 1.7 and 2.3 mm, respectively (p < .001). Conclusions: Left-sided varicocele was significantly more common in patients with EP or EPO and it is an important cause for the development of EP/EPO because of chronic venous stasis.
