Treatment of male varicoceles by transcatheter polidocanol foam sclerotherapy: evaluation of clinical success, complications, and patients' satisfaction with regard to alternative techniques.

OBJECTIVES

We report our experience with polidocanol foam sclerotherapy with no additional coils, evaluating clinical success, patients' satisfaction, and complications.

METHODS

We conducted a retrospective study of 141 patients with 146 varicoceles (mean age: 29.3 years; range: 13 - 60 years) who underwent foam sclerotherapy with polidocanol 2% (range: 2 - 12 ml) in an outpatient setting between January 2007 and December 2013. For the follow-up, telephone interviews with the patients were conducted (mean follow-up time: 46.4 months, standard deviation: 20.17 months).

RESULTS

The technical success rate was 91.8%. There was a 55.8% response rate to the telephone interviews. Follow-up revealed a clinical success rate of 83.9% and a persistence or relapse rate of 16.1%. Of the patients, 81.9% were absolutely satisfied with the outcome. In 94.9% of cases, pain or discomfort resolution was reported, and in 97% of cases, aesthetic issues were no longer a problem. Of partners, 63.2% achieved pregnancy, and in 50% of patients with preprocedural testicular atrophy, catch-up growth was observed. One patient with pampiniform plexus phlebitis received inpatient treatment with no long-term damage recorded.

CONCLUSIONS

Polidocanol foam varicocele sclerotherapy is a safe and effective procedure, with a high rate of patients' satisfaction, clinical and technical success, and considerable catch-up growth and pregnancy achievement.

KEY POINTS: • Varicocele treatment using polidocanol foam sclerotherapy is a safe and effective procedure. • It is easily feasible in an outpatient setting. • The clinical and technical success rates are high. • It shows a high rate of patients' satisfaction and symptom resolution. • Postinterventional catch-up growth and pregnancy achievement are considerable.
