ESPU Congress 2018 - Abstract Book

92 29 th CONGRESS OF THE ESPU MATERIAL AND METHODS Paired data was prospectively collected from a single institution from 2009 to 2017. All patients aged 12 to 17 years post-pubertal with visible or palpable varicoceles and testicular asymmetry (>20 %) were eligible. Patients produced semen samples by masturbation before and 6 months following varicocele surgery. Outcomes were sperm concentration and forward motility. Data is expressed as mean (standard deviation). Paired t test was used to compare pre and post-surgery sperm parameters. RESULTS 28 patients underwent surgery for testicular symmetry, 13 underwent laparoscopic selective vein ligation and 15 underwent antegrade sclerotherapy. 9 of these patients produced paired sperm data (before and 6 months after surgery) and were eligible for inclusion. 7 had visible varicoceles and 2 had palpable varicoceles. All had spontaneous venous reflux on Doppler examination pre-op and all were successfully treated. Pre-op Post-op P value Age (years) 14.4 (1.3) 16.2 (1.6) Abstinence interval (days) 4.4 (1.8) 4.2 (2.2) 0.8 Concentration (millions/ml) 7.2 (10.1) 30.5 (31.3) 0.01* Forward motility (%) 26.1 (22.7) 48.1 (21.5) 0.01* *p<0.05 Pre-op all 9 patients had abnormal sperm parameters (either concentration <15 millions per ml or forward motility <32 %). Post-op 4 out of 9 patients had normal sperm parameters. The remaining 5 patients had improved concentration and forward motility post-op. CONCLUSIONS Varicocele surgery in adolescents with testicular asymmetry significantly improves sperm param- eters and in 44 % restores them to normal. 15:07–15:15 Discussion
