- AimsTo investigate the activity of the T-type calcium channel (TCC) and the expression of its subtypes in overactive detrusor (OD) myocytes in rats after partial bladder outflow obstruction (PBOO).MethodsThirteen male Wistar rats with OD after PBOO (OD group) and eight sham-operated rats (control group) were studied. The two groups were compared regarding the expression of TCC subtype genes by reverse transcription-polymerase chain reaction (RT-PCR) and the TCC kinetics and cell action potential by whole-cell patch-clamp.ResultsThe time course and density of the current were significantly higher in the OD cells than those in the control detrusor. Whole-cell patch-clamp analysis showed that the activation of TCCs in detrusor myocytes in the OD group was faster than the control group, but inactivation was almost the same in both groups, suggesting a significant enhancement of the Ca2+ window current in the OD group. Patch-clamp recording of action potentials in the OD cells indicated an increase in excitability and a decrease in the repolarization interval. RT-PCR assay showed an abnormal expression of 1G subtype in the OD cells.ConclusionsTCCs could be one of the crucial factors for the abnormal excitation in OD cells. The development of OD after PBOO presumably relates to the increase in TCC current in the bladder cells, the enhancement of the Ca2+ window current for Ca2+ inflow, the prolongation of the intracellular calcium oscillations, and the acceleration of the cell depolarization.

- INTRODUCTION AND HYPOTHESIS: The objective was to determine predictors of long-term success in women with stress urinary incontinence (SUI) treated with a 3-month pelvic floor muscle training (PFMT) program delivered via the Internet or a brochure.METHODS: We included 169 women with SUI ≥1 time/week who completed the 1-year follow-up (n = 169, mean age 50.3, SD 10.1 years). Three outcome variables defined success after 1 year: Patient Global Impression of Improvement (PGI-I), International Consultation on Incontinence Modular Questionnaire Urinary Incontinence Short Form (ICIQ-UI SF), and sufficient treatment. Using logistic regression, we analyzed data from the baseline, and from the 4-month and 1-year follow-ups, for potential predictors of success.RESULTS: Of the participants, 77 % (129 out of 169) were successful in ≥1 of the outcomes, 23 % (37 out of 160) were successful in all 3. Participants with successful short-term results were more likely to succeed in the corresponding outcome at 1 year than those without successful short-term results (adjusted odds ratios [ORs]: PGI 5.15, 95 % confidence interval [CI] 2.40-11.03), ICIQ-UI SF 6.85 (95 % CI 2.83-16.58), and sufficient treatment 3.78 (95 % CI 1.58-9.08). Increasing age predicted success in PGI-I and sufficient treatment (adjusted OR 1.06, 95 % CI 1.02-1.10, and 1.08, 95 % CI, 1.03-1.13 respectively). Compared with not training regularly, regular PFMT at 1 year predicted success for PGI and sufficient treatment (adjusted OR 2.32, 95 % CI 1.04-5.20, and 2.99, 95 % CI 1.23-7.27 respectively).CONCLUSION: The long-term success of a non-face-to-face treatment program for SUI with a focus on PFMT can be predicted by successful short-term results, increasing age, and the performance of regular PFMT after 1 year.

- AIMS: To examine the impact of female urinary incontinence, urgency and frequency on quality of life, and partner relationship in women (18-74 years) and their partners, and make comparisons with the corresponding age groups in a Swedish population-based study.METHODS: Women with urinary incontinence, urgency and frequency (n = 206) completed specific questionnaires concerning medical history and the Bristol Female Lower Urinary Tract Symptoms questionnaire. Women who had a stable relationship (n = 170) also answered a questionnaire regarding psychosocial situation, partner relationship and sexual life, and were asked to give a similar questionnaire to their partner. Totally, 109 partners participated.RESULTS: The vast majority of the women considered that their urinary problems affected their physical activities negatively and almost half reported negative consequences for social life and joint activities. One third of both women and men experienced a negative impact on their relationship and about every fifth felt it had a harmful influence on physical proximity, intimacy, affection, and warmth. Compared to the older women, the younger were less satisfied with their psychological health, sexual life, leisure and financial situation, and compared to the younger men, the young women were less content with their somatic health. Overall, women with urinary problems and their partners were less satisfied with their somatic health than the corresponding age groups in the national population-based study.CONCLUSIONS: Female urinary incontinence, urgency and frequency significantly impair the quality of life in both younger and older women, and also have negative effects on the partner relationship and the partner's life.

- Aim: To investigate the urethral motor function in incontinent women. Materials and Methods: The intraurethral pressure was measured continuously in the high-pressure zone of the urethra at rest and during repeated short squeezes around the microtip transducer catheter in a group of 205 women with clinically manifest urinary incontinence (severe), and compared with the findings of investigations in 87 middle-aged women (53-63 years) with treatment naive incontinence (mild-to-mode rate) and healthy controls. Results: Women with established incontinence significantly (P < 0.001) more often (66%) had a pressure fall during or immediately following squeeze than women with treatment naive incontinence (35%) or asymptomatic women (25%). The acceleration of urinary flow and the maximal flow rate were significantly (P < 0.01) increased in patients with incontinence: acceleration was 13 +/- 2.2 (17.8), 20 +/- 2.8 (18.9), and 32 +/- 4.9 (24.9) degrees (mean +/- SEM;SD) for incontinence, naive incontinence and no incontinence, respectively; maximum urinary flow rate was 23, 22, and 16 ml/sec. No statistical differences in any of these measures were seen when stress and urge incontinence were compared. Conclusion: Women with stress, urge, and mixed urinary incontinence seem to have a primary neuromuscular disorder in the urethra, which presents itself as an overactive opening mechanism with a urethral pressure fall instead of a pressure increase on provocation during the filling phase of the bladder, and during bladder emptying a more efficient opening of the bladder outlet than in normal women. We suggest that one and the same pathophysiological mechanism participates in female stress, urge, and mixed incontinence.

- Aims: To assess the impact of female urinary incontinence (UI) and urgency on women's and their partners' sexual life in sexually active couples and to elucidate the concordance of answers within couples. Methods: Women aged 18-74 years with UI and/or urgency (n = 206) were consecutively recruited from four outpatient clinics. Those with a partner (n = 170) completed a questionnaire regarding relationship and sexual life and gave a similar questionnaire to him. The present paper focuses on 99 couples with an active sexual life. Results: Twenty-two percent of the men and 43% of the women stated that the female urinary symptoms impaired their sexual life. Forty-nine percent of the women expressed worries about having urinary leakage during sexual activity, but most of their men, 94%, did not. Twenty-three percent of the men and 39% of the women responded that the woman leaked urine during sexual activity. The majority, 84%, of women considered this a problem, but 65% of their partners did not. Except for this disparity, the rest of the answers were significant concordant within the couples. Conclusions: Female UI and urgency negatively affected sexual life in almost half of the women and in every fifth partner. A need for information and advice concerning sexual issues due to the woman's urinary disorder was found in one fifth of the couples. The majority of women with urinary leakage during sexual activities considered this as a problem, but most of their partners did not. Overall, the concordance of the answers within the couples was high.

- Many complex disorders have been found to have a heritable component, including lower urinary tract dysfunction. Twin studies have indicated that genetic contributions to urinary incontinence (UI) may be as important as environmental influences. Linkage to chromosome 9 has been demonstrated in families with pelvic organ prolapse and stress UI. An increasing number of incontinence specialists are studying subjects with lower urinary tract dysfunction using single nucleotide polymorphisms, linkage analyses of siblings, and large association studies. These findings have exciting implications for future prevention and treatment of UI.

- AIMS: To determine whether changes in questionnaire scores on symptoms and condition-specific quality of life reflect clinically relevant improvements in women with stress urinary incontinence (SUI).METHODS: We retrospectively analyzed questionnaires collected during a randomized controlled trial in women with SUI, that received pelvic floor muscle training (PFMT) in two different formats. We included 218 women that answered validated self-assessment questionnaires at baseline and at a 4-month follow-up. We registered changes on two questionnaires, the International Consultation on Incontinence Modular Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) and the Lower Urinary Tract Symptoms Quality of Life (ICIQ-LUTSqol). We compared these score changes to responses from the Patient Global Impression of Improvement (PGI-I) questionnaire. Differences were analyzed with the Spearman rho and one-way-ANOVA. The minimum important difference (MID) was the mean change in score for women that experienced a small improvement.RESULTS: The PGI-I correlated significantly to both the ICIQ-UI SF (r = 0.547, P < 0.0001) and ICIQ-LUTSqol (r = 0.520, P < 0.0001). Thus, larger reductions in symptoms or quality of life scores were associated with greater impressions of improvement. The changes in ICIQ-UI SF and ICIQ-LUTSqol scores were significant across all PGI-I groups from "no change" to "very much improved" (P < 0.05). The MIDs were 2.52 (SD 2.56) for ICIQ-UI SF and 3.71 (SD 4.95) for ICIQ-LUTSqol.CONCLUSIONS: The change in ICIQ-UI SF and ICIQ-LUTSqol scores after PFMT reflected clinically relevant improvements in women with SUI. The MIDs established for this population may facilitate future research, treatment evaluations, and comparisons between studies.

- Abnormalities of micturition occur in many different diseases, have a variety of causes and take several forms. This review will focus exclusively on those abnormalities in which antidiuretic therapy may be of benefit. These conditions are primarily characterized by an increase in the total amount of urine produced (polyuria) or a circadian shift in the control of urine production and/or voiding (nocturnal enuresis, nocturia).
