Abstract
Fifteen patients with nonseminomatous tumors of the testis, stages I and II, underwent a retroperitoneal block dissection as part of their treatment regimen. Nonseminomatous germ cell and paratesticular tumors were reported. The preoperative measures and operative technique of the anterior transabdominal approach are described. There were no deaths or major postoperative complications encountered, in spite of the magnitude of the surgery involved. In two patients the tumor had occurred in an undescended testis. No patient had normal ejaculatory function after the operation. Special attention is drawn to the proper management of patients having undergone a transscrotal biopsy or orchiectomy. Five patients with a relatively long-term follow-up, are free of disease and doing well.
