[Clinical and sperm follow-up after subinguinal varicocelectomy].
In order to evaluate the sperm output and the adverse-side-effects after subinguinal varicoceloctomy, a follow-up study of 16 months was performed on 196 selected patients (aged from 22 to 43 years) affected by left varicocele (VR). In the pre-treatment, both Doppler ultrasonography and didymo-epididymal ultrasonography allowed to distinguish two homogeneous patient groups: group A (no. = 136), including patients affected by VR alone and, group B (n. = 60), including patients with VR combined to coincidental didymo-epididymal morphological abnormalities, DEMA). These DEMA lesions (testis size < 12 ml, epididymides abnormalities: increased head- > or = 12 mm- and/or tail- > or = 6 mm-diameter, multiple microcysts, large idrocele) were omolaterally to VR in 30/60 (50%), eterolaterally in 19/60 (31.7%) or bilaterally in 11/60 (18.3%). During sperm follow-up, group A patients showed both a significant temporal change (p < 0.01 ANOVA) of all sperm parameters studied (sperm density, total sperm count, motility and morphology) from month 8 onward and sperm values significantly higher than found in group B patients. On the contrary, the sperm parameters of group B patients did not change significantly during the follow-up observations. As far as the varicocelectomy-mediated clinical symptoms, some patients complained early and transiently (on 1-2-4 weeks following varicocelectomy) the following symptoms: didymal pain (1.5%), didymo-epididymal pain (4.1%) and parasthesiaes on the anterior-medial side of the left thigh (4.1%) or scrotal (3.1%); only four patients (2%) complained permanent paresthesiaes on the anterior-medial side of the left thigh. Furthermore, the clinical follow-up also revealed a low rate of complications: persistent VR (3.6%), hydrocele (1.5%), intrascrotal venous ecstasies (6.1%), epididymitis (0.5%). Some morpho-structural abnormalities at US scans were transient (1-2 weeks): scrotal oedema (6.1%), orchitis (2%), orchi-epididymitis (1%). Subinguinal varicocelectomy performed on large population demonstrated a significant improvement of the sperm output from month 8th onward in patients with VR alone, while sperm parameters did not show any significant change in patients with VR plus coincidental DEMA. This surgical technique also demonstrated safety since both low rates of symptoms and (transient) complications were registered.
