Neuro-urological sequelae of lumbar spinal stenosis

Lumbar spinal stenosis (LSS) is characterized by the narrowing of the spinal canal, which subsequently induces impingement of neural elements in the lumbar spine. Thus, symptoms of LSS are typically associated with damage to those neural elements. Herewith, we target the genitourinary symptoms of LSS and the importance of differentiating these symptoms from other genitourinary pathologies, namely benign prostatic hyperplasia. Specifically, we review bladder dysfunction, lower urinary tract symptoms (e.g., urinary incontinence, detrusor overactivity and under-activity, as well as frequent urinary tract infections), renal osteodystrophy, and sexual dysfunction (e.g., erectile dysfunction and priapism) in association with LSS. It is imperative for the urologist to conduct a thorough history and physical examination so that they will not misdiagnose secondary genitourinary manifestations of LSS as primary problems or misunderstood secondary problems. Urological consultations are also integral to prioritizing patients with the highest risk of bladder damage for corrective spinal surgery.
