Diabetes mellitus and bladder function.: What should be considered?

Increasing prevalence of diabetes mellitus and rising patient life expectancy are causing an accumulation of urologic late complications - despite or due to steadily improving medical health care. The prevalence of diabetic cystopathy (impaired bladder sensation, increased bladder capacity sometimes accompanied by voiding difficulties and residual urine) is 25% in non-insulin-dependent diabetics and 48% in insulin-dependent diabetics. Autonomic and peripheral neuropathy lead to detrusor hyposensitivity, and chronic., overstretching of the bladder causes myogenic detrusor hypocontractility. Since diabetic cystopathy often develops insidiously and asymptomatically, prevention of secondary complications such as recurrent urinary tract infections, vesico-renal reflux, nephrolithiasis, and pyelonephritis requires the urologist's full attention as well as early and repeated urodynamic diagnostics. Comorbidities can lead to a variety of urodynamic findings. Therapeutic options are generally conservative (timed voiding, micturition training, CIC, pharmacotherapy) and should be part of an integrated interdisciplinary health care approach since undiscovered complications involving non-urologic organ systems create a higher long-term socioeconomic burden than preventive support provided by other specialists.
