Voiding Difficulty Common in Diabetic Women
posted 04/16/04
Women with type 2 diabetes are nearly five times more likely
to have unrecognized voiding difficulty compared with nondiabetic control
subjects.
That, from the results of a prospective study of 338 women
seen at an outpatient clinic between July 2001 and June 2003.
In a study published in the April issue of Diabetes Care, Dr. Hong-Jeng Yu and
colleagues from National Taiwan University, Taipei, examined the prevalence of
voiding difficulty in 176 female diabetics and 162 age-matched, non-diabetic
controls.
All of the patients completed questionnaires regarding symptoms. The researchers
used a rotating disc flow meter to perform uroflow analysis. In addition,
postvoid residual urine was measured by urethral catheterization immediately
after voiding in patients and by abdominal ultrasound in controls. The team
defined voiding difficulty as a maximal flow rate (Qmax) of less than 12 mL/s or
a PVR of at least 100 mL on two or more determinations.
The investigators found that 22.2% and 5.6% of diabetic patients and controls,
respectively, experienced voiding difficulty (odds ratio 4.8). "In the diabetic
group, patients with voiding difficulty reported a higher prevalence of weak
urinary stream, intermittence, and hesitancy than those without voiding
difficulty," Dr. Yu and colleagues write.
After controlling for age, duration of diabetes of at least 20 years and at
least two episodes of urinary tract infection in the previous year were
independent predictors of voiding difficulty.
"Asking questions about urinary symptoms, paying attention to significantly
associated clinical factors, and measuring postvoid residual urine regularly in
these patients may help to identify those at risk for voiding difficulty," Dr.
Yu and colleagues conclude.
