The skin response in evaluation of the sympathetic chains after retroperitoneal lymphadenectomy. Preliminary report.

The sympathetic skin response (SSR) permits recording of the sympathetic amyelinic fibres activity in relation to the function of sudoriparous glands. We recorded the SSR to check the efficacy of "nerve-sparing" technique in surgery of the sympathetic retroperitoneal postganglionic fibres following lymphadenectomy in nonseminomatous testis cancer. The results showed that SSR can be used to verify the integrity of the lumbar sympathetic chains after retroperitoneal lymphadenectomy.
