Migration of varicocele coil leading to ureteral obstruction and hydronephrosis: A case report

Abstract

BACKGROUND

Varicocele embolization, a minimally invasive treatment for symptomatic varicoceles, carries a rare risk of complications like ureteral obstruction and hydronephrosis. This case report documents such a case to raise awareness of these potential complications and showcase minimally invasive surgical management as a successful solution.

CASE SUMMARY

A 35-year-old male presented with flank pain and hematuria following varicocele embolization. Imaging confirmed left ureteral obstruction and hydronephrosis. Laparoscopic ureterolysis successfully removed the embolization coil and repaired the ureter, resolving the patient's symptoms. Follow-up at six months and two years showed sustained improvement.

CONCLUSION

Minimally invasive surgery offers an effective treatment option for rare complications like ureteral obstruction arising from varicocele embolization.

Core Tip: Varicocele embolization is a minimally invasive procedure that is generally considered safe, but complications can occur, such as ureteral obstruction and hydronephrosis. It is important to be aware of the potential complications of varicocele embolization, even though they are rare. Minimally invasive surgery can be used to successfully treat the complications of varicocele embolization. If a patient develops flank pain and hematuria following varicocele embolization, imaging studies should be performed to rule out ureteral obstruction and hydronephrosis. If the ureteral obstruction is diagnosed, minimally invasive surgery can be performed to remove the obstructing coil and repair the ureter.
