Benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS) is a common health problem affecting 50% of men older than 50 years of age, and similarly, diabetes mellitus (DM) is another common disease occurring in the same age group. Both affect bladder function producing obstructing and irritative symptoms. The distinction between LUTS secondary to DM and BPH is difficult and often they overlap. It is in such a situation where urodynamic evaluation plays an important role to distinguish the primary cause of LUTS and thereby helping the urologist in deciding the appropriate line of management.
Diabetic bladder dysfunction presents in a spectrum of clinical symptoms representing a number of disorders ranging from bladder overactivity to impaired bladder contractility. Its prevalence has been estimated as being between 25% and 87% (Frimodt-Møller, 1980). Diabetic bladder dysfunction can also present as an overactive bladder (OAB) syndrome. More than half (~55%) of diabetic patients have detrusor hyperreflexia (DH), 23% have decreased detrusor contractility (DU), 10% demonstrate detrusor areflexia (DA) with remaining 11% showing indeterminate findings.
The term diabetic cystopathy was used by Frimodt Moller in 1976 and refers to LUTS due to diabetic neuropathy. Diabetic cystopathy is characterized by increased postvoid residual volume and enhanced bladder capacity with decreased bladder sensation and contraction secondary to damage of visceral afferent fibers in bladder wall. It is a well-recognized complication of DM which usually develops in middle-aged or elderly patients with long-standing or poorly controlled disease.
Two indices have been used to predict bladder outlet obstruction (BOO) and bladder contractility, i.e., BOO index (BOOI) and bladder contractility index (BCI) which are derived as follows:
BOOI = Pdet Qmax-2Qmax
BCI = Pdet Qmax-+5Qmax
BOOI > 40 = BOO, BCI < 40 DU
Diabetic patients with voiding dysfunction have varied urodynamic findings.
Findings of UDS in various studies of patients with DM are shown in [Table 1].
To conclude, urodynamic study plays an important role in helping the urologist to decide the line of management in diabetic male patients with LUTS. In addition to this, some authors acknowledge that urodynamic analysis can be used to predict the symptomatic outcome after TURP.
