Varicocele, conventional laparoscopic ligation versus occluding balloon embolization

Abstract

Introduction

Varicocele is a relatively complex pathology that affects the pampiniform plexus of veins in the spermatic cord. Modern treatment involves both urological/surgical and interventional procedures. Our objective is to compare outcomes of conventional laparoscopic ligation (LL) and occluding balloon embolization (OBE) a percutaneous interventional procedure.

Materials and methods

We treated retrospectively a total of 98 patients, divided in two cohorts; arm A with 48 and arm B with 50 patients. Arm A patients underwent LL, while arm B ones were treated in interventional radiology suite, via OBE method. No comorbidities were reported, especially scrotal ones. Hence, all patients have been asked to respect 3 and 6 months' follow-up, clinical examination and ultrasonography were performed. Age range of the entire sample: 15–45 years old, with average of 28 years. The study involved two European centers. We performed a comparative analysis (Fisher's test) of intra-operative time, hospitalization and patient's postoperative recovery time.

Results and limitations

Outcomes have been in line with the recent literature ones, allowing the occluding balloon embolization a small advantage for quicker operative average time, hospitalization needed and full recovery to normal activities for the patient. Main limitation was the unfeasibility of cost-effectiveness analysis due to national differences, limited sample and lack of complete semen analysis pre- and postoperative.

Conclusion

Both OBE and LL are safe and effective procedures in the treatment of varicocele, conceding OBE a slight advantage in terms of hospital stay and full recovery to normal activity of patients.
