Summary

Transurethral sphincterotomy in spinal cord injury patients can lead to significant long-term upper and lower urinary tract complications, despite initial improvements in bladder function. Careful monitoring is crucial for managing risks associated with this procedure.

Area of Science:

  • Urology
  • Neurosurgery
  • Rehabilitation Medicine

Background:

  • Transurethral sphincterotomy is a frequent intervention for managing bladder dysfunction in spinal cord injury (SCI) patients.
  • Long-term outcomes and associated risks require thorough investigation to optimize patient care.

Purpose of the Study:

  • To evaluate the long-term risks and identify predictors of outcomes following transurethral sphincterotomy in SCI patients.
  • To assess the incidence of upper and lower urinary tract complications after the procedure.

Main Methods:

  • Retrospective analysis of 63 SCI patients who underwent transurethral sphincterotomy.
  • Comprehensive evaluation including urodynamics, renal function tests, urine cultures, and imaging (IVP/KUB, VCUG).
  • Assessment of complications such as infection, stones, reflux, and renal damage.

Main Results:

  • 30% of patients experienced significant upper tract complications (renal calculi, atrophic kidney, reflux, scarring) often developing >2 years post-procedure.
  • 30 patients suffered lower tract complications including recurrent UTIs, stones, and urethral issues.
  • Videourodynamics revealed prevalent detrusor hyperreflexia (60 patients) and detrusor sphincter dyssynergia (34 patients).
  • Renal function was largely preserved, with only 2 patients showing abnormalities.

Conclusions:

  • Transurethral sphincterotomy carries a substantial risk of long-term upper and lower urinary tract complications in SCI patients.
  • The findings underscore the need for vigilant, long-term follow-up and risk stratification for this patient population.
  • Further research into predictive factors may aid in personalized treatment strategies.
