Abstract

Study Design: Retrospective cohort study. Purpose: To analyze the clinical and sphincteric outcomes and the extent of sexual dysfunction (SD) in subjects with cauda equina syndrome (CES) and to assess their correlation with patient-reported and clinical/urodynamic parameters. Overview of Literature: Despite vast literature present for CES, extent of the problem of SD in CES patients has not received enough attention as reflected by the limited information in literature. Little is known about exact prevalence at presentation or about the recovery. A better understanding of SD and bladder dysfunction in CES secondary to lumbar disc herniation is essential as it commonly occurs in the sexually active age group.
Methods
All cases of cauda equine syndrome secondary to lumbar disc herniation were recruited. Biographical and clinical data, history, examination findings, operative variables, recovery, and SD were noted. Water cystometry and uroflowmetry were done pre- and postoperatively. The International Index of Erectile Function questionnaire and Female Sexual Function Index were used to assess SD among the men and women, respectively.
Results
A total of 43 patients with up to 2.94-year follow-up were included. Urodynamic studies were found to correlate significantly with age, days of bladder involvement, perianal numbness, and motor weakness (p<0.01). In step-wise regression analysis, perianal sensation and overall motor weakness were bladder function determinants. Bladder function recovery was directly related to the number of delay days (t=2.30, p<0.05) and with unilateral leg pain (t=2.15, p<0.05). Significant correlation between SD with age and days of bladder involvement before surgery was found (p<0.01).
Conclusions
Surgery timing is related to patient’s functional and sexual outcomes. Patients with unilateral leg pain and hypocontractile bladder have better outcomes. SD is a remarkable problem in CES.
