title: Predictive factors of successful redo varicocelectomy in infertile patients with recurrent varicocele.
abstract: To examine the predictive factors of successful redo varicocelectomy in infertile patients with recurrent varicocele, we made a retrospective study. Twenty-one patients who had improved quality of spermatozoon 6 months after RV were designated as group 1, those with no improvement as group 2 (17 subjects) and those who received close surveillance as group 3 (10 patients) were recruited. The predictive factors included were time to recurrent varicocele; semen quality; testicular volume; number of ligated veins; body mass index; serum levels of follicle-stimulating hormone (FSH), luteinising hormone and testosterone; scrotal temperature; and peak retrograde flow (PRF) and maximal vein diameter (MVD) by colour Doppler ultrasound. The quality of spermatozoon improved significantly 6 months after RV in group 1 patients (21, 55.3%), and no improvement in group 2 and 3 patients. Patients in group 1 also had significantly lower FSH and PRF, longer time to recurrent varicocele, higher number of ligated veins and larger testicular volume than the group 2 (17, 44.7%) and group 3 patients. The significant predictive factors of successful RV were lower FSH and PRF; longer time to recurrent varicocele; and larger testicular volume preoperatively and a higher number of ligated veins during redo varicocelectomy.
