Dysfunctional voiding, a condition without a clear neurological cause, caused significant morbidity in 40% of patients. Nonoperative treatments cured 30%, while another 30% had unresolved symptoms.

Area of Science:

  • Urology
  • Pediatric Urology
  • Neurourology

Background:

  • External sphincter dyssynergia, often termed dysfunctional voiding, can lead to significant patient morbidity.
  • This condition occurs without an identifiable neurological lesion and is also known as Hinman-Allen syndrome or non-neurogenic neurogenic bladder.

Purpose of the Study:

  • To determine the clinical outcomes and morbidity associated with dysfunctional voiding.
  • To evaluate the effectiveness of various treatment modalities for this condition.

Main Methods:

  • A retrospective study was conducted on 37 patients diagnosed with dysfunctional voiding via urodynamic studies.
  • Follow-up involved chart review and physician/patient telephone calls for 27 patients.

Main Results:

  • Of 27 patients followed for a mean of 49 months, 11 (40%) developed significant morbidity, with 10 undergoing 17 operations.
  • Eight patients (30%) were cured with nonoperative treatments (medication, behavioral modification, intermittent catheterization).
  • Eight patients (30%) had unresolved symptoms, and most were lost to follow-up.

Conclusions:

  • Dysfunctional voiding is associated with substantial morbidity, affecting 40% of patients in this cohort.
  • Nonoperative and conservative treatments achieved cure in 30% of patients.
  • Urodynamic studies are crucial for diagnosis but do not consistently predict patient outcomes.
