High rate of urinary symptoms in older HSPers

Posted - December 2018 in Living with HSP - Management & Treatment News

Impaired bladder function the main cause

 

9 out of 12 HSPers averaging 65 years old and almost 20 years with HSP experienced urinary symptoms, mainly:

  • bladder overactivity during filling, and

  • under activity during emptying.

This combination is known as DHIC (detrusor hyperactivity with impaired contraction).

 

Abstract

In order to investigate lower urinary tract function in hereditary spastic paraplegia (HSP), we recruited 12 HSP patients: 8 men, 4 women; mean age, 64.6 years; mean disease duration, 18.9 years; walk without cane, 2, walk with cane, 6, wheelchair bound, 3.

 

We performed urinary symptom questionnaires and a urodynamic testing in all patients. As a result, urinary symptoms were observed in all but 3, including urinary urgency/frequency (also called overactive bladder) in 9 and hesitancy/poor stream in 6. Urodynamic abnormalities included detrusor overactivity during bladder filling in 10, underactive detrusor on voiding in 8 (detrusor hyperactivity with impaired contraction [DHIC] in 5), detrusor-sphincter dyssynergia (DSD) on voiding in 3, and post-void residual in 5. Sphincter electromyography showed neurogenic motor unit potential in 4.

 

In conclusion, we observed high frequency of urinary symptoms in HSP. Urodynamics indicated that the main mechanism is DHIC with/without DSD for their urinary symptom, and sacral cord involvement in some cases. These findings facilitate patients’ care including clean, intermittent catheterization.

    It is hard to get assistance with managing the problem. More male professionals who could recommend the correct products and fitting would be good. We have not approached NDIS and patient is reluctant to follow up “aged care” suggestions.
