Evaluation of urodynamic pattern in short and long-standing diabetic patients

PURPOSE

To address the pattern of urodynamic findings in diabetic patients with lower urinary tract symptoms (LUTS), comparing short-standing and long-standing type 2 diabetes mellitus (T2DM).

METHODS

A prospective study was conducted on 50 patients presenting with LUTS and a concurrent diagnosis of T2DM, between February 2016 and May 2018. Patients were classified and evaluated according to the duration of diabetes into two groups: short-standing DM (< 15 years, n = 31), and long-standing DM (≥ 15 years, n = 19) groups. The impact of LUTS and quality of life were assessed in female patients using ICIQ-FLUTS and male patients using ICIQ-MLUTS.

RESULTS

A total of 50 patients were included in the study. The mean duration of T2DM was 10 ± 0.7 years. The mean age was 56.3 ± 1.2 years, and the mean HbA1c was 7.5 ± 1.2%. Urodynamic evaluation detected significantly higher detrusor overactivity (DO) and increased bladder sensation with the short-standing DM group (35.5 vs. 15.8%, p = 0.01 and 32.3 vs. 5.3%, p = 0.01, respectively). Comparatively, weak, or absent detrusor contractility were more frequent in patients with long-standing DM (52% and 26% respectively p = 0.01). As expected, overflow incontinence and straining during voiding were significantly higher in the long-standing DM group (p = 0.04 and p = 0.03, respectively). Surprisingly, there was no significant correlation between patients presenting with urgency in their voiding diary (subjective) and urodynamic detection of DO (p = 0.07).

CONCLUSIONS

There are different patterns in urodynamic characterizations of T2DM. Patients with short-standing DM present more commonly with storage symptoms and detrusor overactivity on urodynamics. Contrastingly, patients with long-standing DM present more frequently with voiding symptoms and detrusor underactivity on urodynamics. Thus, screening for an underactive bladder is advisable in patients with long-standing T2DM.

The prevalence of lower urinary tract symptoms in population aged 40 years or over, in South Korea

Purpose

Lower urinary tract symptoms (LUTS) can be distressing and socially isolating, and the economic impact can be substantial. Further data to characterize the epidemiology and effects of LUTS in South Korea would be beneficial.

Materials and Methods

In an international, internet-based survey, the prevalence and impact of LUTS was evaluated in adults aged ≥40 years. Questions related to International Continence Society (ICS) symptom definitions and the bother associated with each symptom. The international prostate symptom score (IPSS) and the overactive bladder symptom score (OABSS) were assessed.

Results

Of the 2,080 participants from South Korea, 1,090 (52.4%) were women and 740 (35.6%) were aged ≥60 years. The prevalence of LUTS according to ICS criteria was 68.2% (men, 70.6%; women, 66.0%). LUTS prevalence increased significantly with age (p=0.01 in men and women). Storage symptoms only were reported in 16.2% of men and 30.5% of women, making this the most common ICS symptom group overall. Individual symptoms with the highest prevalence in the overall population were nocturia, frequency, and weak stream (36%, 30%, and 29%, respectively). IPSS results showed that 40.1% of participants had at least moderate symptoms. The prevalence of OABSS-defined overactive bladder was 19.7% (men, 19.5%; women, 19.9%). Fourteen percent of individuals with any LUTS visited healthcare professionals regarding urinary symptoms.

Conclusions

LUTS affect the majority of adults aged ≥40 years in South Korea. The low percentage of individuals with LUTS consulting healthcare professionals regarding urinary symptoms indicates a need to improve rates of diagnosis and treatment.
