1758 MULTIDISCIPLINARY APPROACH FOR VARICOCELE ease. Ofthe patients 251 with 277 total varicoceles were treated with sclero-embolization. In the majority of these cases a transbrachial approach was used. Open surgery was performed initially in 88 patients with 89 total varicoceles. The decided advantage of percu- taneous sclero-embolization was obviously an institutional bias, based on the experience of the authors with the procedure. Of the varicoceles 79% disappeared and, thus, treatment was considered successful in those cases. Of 42 patients with residual varicoceles 7 underwent a second sclero-embolization and 35 underwent surgery.

Open surgery was performed initially in 88 patients with 89 total varicoceles.

Of the varicoceles 79% disappeared and, thus, treatment was considered successful in those cases. Of 42 patients with residual varicoceles 7 underwent a second sclero-embolization and 35 underwent surgery. Of the patients who underwent sclero-embolization 17 had painful swelling of the scrotum and 4 (2%) were hospitalized for a few days.

Of surgical treatments 89% were considered successful. Six pa- tients underwent a second operation. Complications in the surgical group included an 11.28 incidence of late hydrocele. Only 2 of the 15 patients with a hydrocele required surgery. The authors noted a marked improvement in surgical outcome, since ligation of the entire spermatic cord above the vas deferens.

Several issues need to be addressed when evaluating this type of new approach toward varicocelectomy. One must look at short-term outcome data. We must understand the morbidity and cost of the less invasive versus the time-honored surgical procedure. Finally, one must always consider the ultimate long-term outcome. With respect to the short-term outcome, the authors quoted a 79% success rate for sclero-embolization, including what they term partial success. It is unclear what a partial success indicates and removing that data appears to drop the overall success rate significantly.
