title: Electrostimulation of sympathetic nerve fibers during nerve-sparing laparoscopic retroperitoneal lymph node dissection in testicular tumor.
abstract: A long-handled pair of electrodes with sufficient length to allow stimulation during laparoscopic retroperitoneal lymph node dissection (RPLND) was designed at our institute. We clinically utilized this electrode in the treatment of a 37-year-old patient with testicular tumor who underwent right orchidectomy and nerve-sparing laparoscopic RPLND. During laparoscopic RPLND, sympathetic nerve fibers relevant to ejaculation were electrically stimulated and changes in pressure at the bladder neck were observed. Nerve preservation was confirmed by increased pressure at the bladder neck and ejaculation immediately after the electrostimulation. The application of laparoscopic electrostimulation may become widespread, particularly since it meets the increasing demand for minimally invasive surgery.
