Study DesignThis is a prospective study.ObjectiveA 2-year outcome of erectile dysfunction (ED) in patients younger than 50 years with fracture-unrelated lumbar spine disease requiring surgical decompression for ED is evaluated. Risk factors for ED were also evaluated.Summary Of Background DataThere is no literature documenting 2-year follow-up of ED status in young patients with atraumatic lumbar spine disease.MethodsAll male patients younger than 50 years who underwent lumbar spine surgery between June 2006 and November 2007 without risk factors for ED were included. Patient demographics, neurological dysfunction, visual analogue scale (VAS) for back and leg pain, Oswestry Disability Index, North American Spine Society score for neurogenic symptoms, and the international index of erectile function-5 scores were recorded preoperatively and at 2 years. Patients who did not complete a 2-year follow-up were excluded. RESULTS.: A total of 75 patients were eligible for the study. Nineteen patients did not complete a 2-year follow-up giving a response rate of 75%. There were 56 patients in the study with a mean age of 38.4 (SD, 7.2; range, 20-49). The most common diagnosis was prolapsed intervertebral disc (77%) for which patients underwent discectomy. Preoperatively, 21 of 56 (37.5%) patients had ED. Despite significant improvement in mean VAS scores for back pain and leg pain, Oswestry Disability Index, and North American Spine Society score for neurogenic symptoms at 2 years (P < 0.01), the mean international index of erectile function-5 scores remained stable. Patients with ED at 2 years had greater back pain (mean VAS score 3.4) compared with patients without back pain (mean VAS score, 1.6; P ≤ 0.01).ConclusionDespite excellent outcome in most spine scores postoperatively after lumbar spine surgery, one has to be less optimistic about any improvement in the ED status of patients after surgery. ED is still a problem 2 years after surgery. Back pain reduction may have a significant role in dealing with ED at 2 years postoperatively.Level Of Evidence2.
