Preservation of ejaculation through a modified retroperitoneal lymph node dissection in low stage testis cancer.

We studied ejaculatory function in 47 patients who underwent modified retroperitoneal lymph node dissection for nonseminomatous germ cell tumors of the testis from 1983 to 1989. Our goal was to assess the effectiveness of a modified node dissection in preserving ejaculatory function while eliminating the risk of retroperitoneal recurrence. There were 13 left and 34 right tumors. Of the patients 45 had clinical stage A cancer, and 2 had clinical stage B2 disease and received preoperative chemotherapy. The template method of dissection was used, which spares the preaortic area below the inferior mesenteric artery, including the sacral promontory. Average operating time was 3 hours 40 minutes. There was no operative mortality. Spontaneous recovery of ejaculation occurred in 38 patients (81%), more commonly with right (88%) than with left dissections (62%). The mean interval to recovery of ejaculation was 5 months (92% within 12 months). Five patients (10%) had recurrence, with a mean followup of 28 months. All recurrences were in the lungs 4 to 8 months after retroperitoneal lymph node dissection, and all patients were salvaged with chemotherapy and are disease-free. We confirmed that a modified template-type retroperitoneal lymph node dissection can be accomplished safely with preservation of ejaculation in more than 80% of the patients without increasing the risk of local recurrence.
