Bladder sensations in male and female overactive bladder patients compared to healthy volunteers: a sensation-related bladder diary evaluation.

Objectives: To investigate the differences in bladder sensations of overactive bladder (OAB) patients compared to healthy volunteers. In addition, to see if bladder sensations are different in men and women.Methods: In a prospective, longitudinal study (METC 09-2-095), 66 volunteers and 68 OAB patients were included. Anticholinergic medication was stopped. Subjects filled out a sensation-related bladder diary (SR-BD), for two periods of 3 days, including a 4-points urgency scale and visual analogue scale for perception of bladder fullness.Results: In total, 6160 voids were assessed. Patients voided more often with higher degrees of urge at a lower mean voided volume (193 vs 270 ml/void; p < 0.001) than healthy volunteers. The mean urinary frequency per litre diuresis was also higher (5.8 vs 4.1/l; p < 0.001) in patients. At the same voided volume: patients perceived a higher mean bladder fullness, independent of the degree of urge, and higher urgency (1.4 vs 0.5/100 ml; p < 0.001) than healthy volunteers. There were no gender differences in the above-mentioned voiding parameters, except for the mean voided volume at urge 3 in volunteers (340 ml in men vs 362 ml in women; p = 0.03) and urge 1 in patients (171 ml in men vs 135 ml in women; p = 0.027).Conclusions: Bladder sensations were significantly increased in everyday life for both male and female OAB patients compared to healthy volunteers. OAB patients experienced a higher mean bladder fullness sensation, independent of the degree of urge, and higher mean urge/urgency at the same voided volume than volunteers. Bladder sensations are crucial in the assessment of treatment response.

The discrepancy between European Association of Urology (EAU) guidelines and daily practice in the evaluation and management of nocturia: results of a Dutch survey.

BACKGROUND AND OBJECTIVE: In addition to the evaluation of voiding symptoms, in the evaluation of patients with nocturia, one should also consider other related causes such as sleep disorders, obstructive sleep apnoea (OSAS), diabetes and heart failure. In this study, we have aimed to assess the current knowledge and implementation of the EAU guidelines regarding nocturia in common urological practice in the Netherlands. SETTING AND PARTICIPANTS: In a national cross-sectional survey distributed among 450 urologists and urology residents in the Netherlands, the implementation of the recommendations of the European Association of Urology (EAU) guidelines on nocturia evaluation and management was studied. RESULTS AND LIMITATIONS: This survey revealed that only some aspects of the EAU guidelines are applied in the daily clinical practice and that some important parts are not. For example, only a minority asks about alcohol consumption and symptoms suggestive for diabetes or OSAS. In addition, a majority reported to use a bladder diary for 1-3 days instead of for a minimum of 3 days as recommended by the EAU guidelines. In the management of nocturia, a trial of timed diuretic therapy is only reported by a minority, whereas the use of beta-3 antagonists, which is not mentioned in the guidelines, is applied by a large majority. Desmopressin recommended for nocturnal polyuria is prescribed by two-third of Dutch urologists. CONCLUSIONS: These observations mandate better education and campaigns to raise the awareness on the EAU-guideline recommendations for nocturia.
