AIM: To assess frequency of urodynamic abnormalities in young men with chronic lower urinary tract symptoms (LUTS). MATERIALS AND METHODS: We assessed 456 men (18-40 years old) with chronic LUTS. Those with the history of urogenital malignancies, neurological disease, urethral stricture or trauma, acute UTI, congenital urological disease, and diabetes mellitus were excluded. Patients were classified by special urodynamic diagnosis. RESULTS: Mean patient age was 25.8 ± 5.9 years old and the mean symptom duration was 12.3 ± 3.2 months. Urodynamic studies showed bladder neck dysfunction in 96 of cases (21%), dysfunctional voiding in 69 (15.1%), detrusor overactivity in 62 (13.6%), small cystometric capacity in 49 (10.7%), and acontractile detrusor in 48 (10.5%), underactive detrusor in 11 (2.4%), low compliance in 18 (3.9%), detrusor overactivity plus acontractile detrusor in 6 (1.3%), low compliance plus small cystometric capacity in 5 (1.0%), detrusor overactivity plus small cystometric capacity together with low compliance in 4 (0.8%), low compliance plus Underactive detrusor in 3 (0.6%) and normal urodynamics in 85 (18.6%). Mean Q(max) in patients with bladder neck dysfunction, dysfunctional voiding, underactive detrusor, acontractile detrusor, underactive detrusor plus low compliance, and acontractile detrusor plus detrusor overactivity were lower than those of the other groups. Mean postvoid residues in patients with underactive detrusor, and underactive detrusor plus low compliance, were higher than those in the remaining groups. Positive four-glass test in patient with normal urodynamic was greater than those in the remaining groups. CONCLUSION: A few clinical symptoms or noninvasive tests were useful in young men with chronic LUTS; hence, urodynamics are advised to make the correct diagnosis in this regard. Neurourol.

Background Urinary dysfunction is common in Parkinson's disease (PD); however, little is known about urinary dysfunction in early and untreated PD patients. Methods Fifty consecutive untreated PD patients (mean age, 66.7; mean disease duration, 23.6 months; and mean Hoehn & Yahr scale, 1.9) were recruited; those with other conditions that might have influenced urinary function were excluded. Patients were evaluated using a urinary questionnaire and urodynamic studies. Results Sixty-four per cent complained of urinary symptoms (storage, 64.0%; voiding, 28.0%). Urodynamic studies showed abnormal findings in the storage phase in 84%, with detrusor overactivity (DO) and increased bladder sensation without DO in 58.0% and 12.0% of patients, respectively. In the voiding phase, detrusor underactivity, impaired urethral relaxation such as detrusor sphincter dyssynergia, and bladder outlet obstruction were present in 50.0%, 8.0% and 16% of patients, respectively. In patients with both storage and voiding phase abnormalities, DO+detrusor underactivity was the most common finding. Few patients experienced urge incontinence and/or quality-of-life impairment owing to urinary dysfunction; none had low-compliance bladder or abnormal anal-sphincter motor unit potential. These urinary symptoms and urodynamic findings were not correlated with gender, disease severity or motor symptom type. Conclusion Urinary dysfunction, manifested primarily as storage disorders with subclinical voiding disorders and normal anal-sphincter electromyography, occurs in early and untreated PD patients. In cases with severe voiding disorder and/or abnormal anal-sphincter electromyography, other diagnoses should be considered.

Detrusor underactivity: A plea for new approaches to a common bladder dysfunction.

Detrusor underactivity (DU) is defined by the International Continence Society as a contraction of reduced strength and/or duration resulting in prolonged or incomplete emptying of the bladder but has yet received only little attention. The purpose of this report is to summarize the ICI-RS meeting in Bristol in 2010 exploring current knowledge on DU and outline directions for future research.
