Purpose This study has been conducted to identify the rate of varicocele recurrence in patients who underwent microscopic subinguinal varicocelectomy at our center. We also aimed to determine the contributing factors to varicocele recurrence. Patients and Methods A total of 34 married male patients who underwent microscopic sub-inguinal varicocelectomy were retrospectively included in this study. The medical records of recruited patients were reviewed. The diagnosis of varicocele was based on physical examination, while recurrent varicocele was diagnosed based on both physical examination and colored doppler ultrasound. We investigated contributing factors to varicocele recurrence, including demographic characteristics (such as body mass index), clinical (varicocele grade and size of dilated veins), and laboratory data (semen analysis). Patients were followed up at 3 and 6 months after surgery. Results The mean age of patients was 32.53 years. The majority of patients had left-sided varicocele (70.6%) and underwent surgery due to scrotal pain (82.4%), with a mean operation duration of 92 minutes. Left-sided varicoceles were grade II in 51.7% of patients, while right-sided varicoceles were grade II in 16.1% of patients. Recurrence occurred in 2.9% after 3 and 6 months. Pain recurred in 8.8% and 10.5% of patients at 3 and 6 months, respectively. Pregnancy rates were 44.1% at 3 months and 11.8% at 6 months after surgery. The grade of varicocele (P = 0.24) and the size of the left dilated vein (P = 0.002) was significantly associated with recurrence. Conclusion There was a significant association of advanced grade on the left side and large vein diameter before and after surgery with an increased rate of recurrence; however, due to the small sample size of our study, more and larger studies are still warranted.
