3 NEUROGENIC UNDERACTIVE DETRUSOR Central (complete/incomplete): Spinal cord injury- trauma, vascular, disc disease, spinal stenosis Spinal cord disease- myelitis, tumor, MS, spina bifida Conus medullaris injury (cauda equina syndrome)

4 NEUROGENIC UNDERACTIVE DETRUSOR (cont.) Peripheral- pelvic plexus injury: Trauma Infection (herpes zoster, Guillain-Barre syndrome) Pelvic tumor extending to nerves Major pelvic ablative surgery (Miles operation, low anterior resection of rectum, radical hysterectomy) Diabetic cystopathy: Decreased bladder sensation Increased capacity Impaired contractility

5 TREATMENT OPTIONS FOR NEUROGENIC UNDERACTIVE DETRUSOR Permanent catheter drainage Intermittent catheterization Sphincterotomy Treatment of all entities aims at adequate bladder emptying and low-pressure storage

6 NON-NEUROGENIC UNDERACTIVE DETRUSOR DOIC (Detrusor Overactivity with Impaired Contractility) Psychogenic urinary retention Long-standing bladder outlet obstruction Aging Idiopathic conditions

8 ICS Standard Urodynamic Test: Uroflowmetry and PVR plus transurethral cystometry and pressure-flow study, all performed in the patient s preferred or most usual position; usually comfortably seated and or standing if physically possible. The patient(s) may be then reported as having had an ICS standard urodynamic test (ICS-SUT)..

16 D.A., 66 years old 6 months ago AUR Following weaning from indwelling catheter he voided only small volumes US: trabeculated bladder, prostate 4 gram, PVR 75cc Urodynamics: Started SIC + Betanechol

17 Repeat Urodynamics

18 TURP

19 L.Y., 64 years old Voiding difficulties for the past 1 years Was treated with alpha-blockers and betanechol without improvement On SIC for the past 2 years, no spontaneous voiding US: trabeculated bladder, prostate 3 grams Urodynamics: Advised to continue SIC

21 W,I., 56 years old Has voiding difficulties for the past 3 years In 27 underwent BNI with symptomatic improvement for several years US: normal bladder, prostate 4 grams Cystoscopy: interpreted as normal Urodynamics: Was started on SIC

22 TURP

23 Detrusor underactivity is defined by the International Continence Society (ICS) as a contraction of reduced strength and/or duration, resulting in prolonged bladder emptying and/or failure to achieve complete bladder emptying within a normal time span. Abrams P, Cardozo L, Fall M, et al. The standardisation of terminology of lower urinary tract function: report from the Standardisation Sub-committee of the International Continence Society. Neurourol Urodyn 22;21: However, the ICS report falls short in specifying parameters for reduced contraction strength, prolonged bladder emptying, or normal time span. Suggested working definition: The underactive bladder is a symptom complex, and is usually characterised by prolonged urination time with or without a sensation of incomplete bladder emptying, usually with hesitancy, reduced sensation on filling, and a slow stream. Chapple CR et al. The Underactive Bladder: A New Clinical Concept?. Eur Urol 68 (215) Based on a consensus group meeting at the International Consultation on Incontinence Research Society and ICS annual meetings in September and October 214.

24 IN SUMMARY: The urodynamic diagnosis of non-neurogenic detrusor underactivity in men with LUTS needs to be based on strict criteria, which are not defined yet. Permanent SIC should be applied in men with LUTS and urinary retention with utmost prudence. In non-neurogenic men with urinary retention, the options of TURP versus permanent SIC should be discussed with the patient.
