- OBJECTIVE:To investigate the prevalence of urinary incontinence in a representative population in Sweden, and to assess to what extent the condition affects daily life and to what degree those afflicted desire treatment.MATERIAL AND METHODS:In a population-based study, a postal questionnaire comprising 12 questions on urinary incontinence was sent to a representative sample of 15 360 randomly selected residents (aged 18-79 years) of Orebro County, Sweden. This was a supplement to a comprehensive survey of public health and general living conditions.RESULTS:The response rate was 64.5%. The prevalence of urinary incontinence was 19% when defined as "any leakage" and 7% when defined as "at least once a week". Women were more afflicted than men, and the proportion of people with urinary incontinence increased markedly with increasing age. Most considered their problems to be minor, having little impact on daily life, which was reflected by the fact that only 18% of those with urinary incontinence desired treatment. About 17% of those with urinary incontinence reported severe problems that interfered with daily life. Of respondents with severe problems, 42% did not want treatment.CONCLUSION:According to this population-based study, urinary incontinence is not a major problem for most people in the community. Although a considerable proportion of the population report urinary incontinence, the majority experience minor problems and only 18% desire treatment. For a limited group of people, urinary incontinence is a severe problem. It is important that healthcare resources are optimized to identify and meet the needs of those who are most afflicted.

- Stimulation of muscarinic receptors is a main mechanism for contractile activation of the detrusor from both animals and humans. Muscarinic receptors are coupled to G-proteins, but the signal transduction systems may vary. In general, M-1 , M-3 and M-5 receptors are considered to couple preferentially to G(q/11) , activating phosphoinositide hydrolysis, in turn leading to mobilization of intracellular calcium through inositol trisphosphate generation. M-2 and M-4 receptors couple to pertussis toxin-sensitive G(i/o) , resulting in inhibition of adenylyl cyclase activity. However, in the detrusor smooth muscle, other signalling pathways may be involved. Recent investigations revealed that a main pathway for muscarinic receptor activation of the detrusor may be calcium influx via L-type calcium channels, and increased sensitivity to calcium of the contractile machinery via inhibition of myosin light chain phosphatase through activation of Rho-kinase. The importance of these findings for treatment of voiding dysfunction remains to be established.

Overactive bladder--pharmacological aspects.

- The micturition reflex can be initiated by contraction or distension of detrusor smooth muscle cells, or by signals from the urothelium. It has been shown that bladder distension causes release of ATP from the urothelium and that ATP can activate P2X(3) receptors on suburothelial afferent nerve terminals to evoke a neural discharge. However, most probably the activation of afferent fibres during bladder filling involves not only ATP, but a cascade of inhibitory and stimulatory transmitters/mediators. These mechanisms may be targets for future drugs. Both in the normal and functionally disturbed bladder, muscarinic receptor stimulation produces the main part of detrusor contraction, but evidence is accumulating that in disease states, such as neurogenic bladders, outflow obstruction, idiopathic detrusor instability, interstitial cystitis, and also in the ageing bladder, a non-cholinergic activation via purinergic receptors may occur. If this component of activation is responsible not only for part of the bladder contractions, but also for the symptoms of the overactive bladder, it should be considered an important target for therapeutic interventions. Drugs blocking different P2X receptor subtypes, or counteracting bladder contraction via other mechanisms. e.g. beta(3)-adrenoceptor stimulation, may be developed for treatment of the overactive bladder.

- Abstract Objective: To report prognostic factors and follow-up data for an unselected group of patients with carcinoma in situ (CIS) of the urinary bladder treated with bacille Calmette-Guérin (BCG). Material and Methods: The clinical records of patients with CIS treated with BCG were reviewed. All 173 patients treated between 1986 and 1997 in four hospitals in two Swedish cities were included. The median follow-up period was 72 months (range 6-154 months). The impact of 18 variables on the times to recurrence and progression was studied using multivariate Cox proportional hazard regression and Kaplan-Meier analyses. Results: No pre-treatment variables, including type of CIS and T1G3 tumour, had prognostic value in terms of time to progression. The result of the first cystoscopy had a very strong prognostic importance: 44% of patients with a positive first cystoscopy progressed in stage, 59% were BCG failures and 35% died from urothelial cancer. The corresponding values for patients with a negative first cystoscopy were 11%, 18% and 8%. Fourteen patients (8%) were diagnosed with an upper urinary tract tumour but no variable had prognostic significance. The diagnoses of the upper urinary tract tumours were evenly distributed during follow-up. Conclusions: We were not able to predict which patients would respond favourably to BCG. Cystectomy should be strongly considered even after a positive first cystoscopy. The accumulated incidence of patients with bladder CIS and a subsequent upper urinary tract tumour is rather high but it is questionable whether the prognosis will improve if routine follow-up urographies are performed.

- Objective: To evaluate whether the free-to-total prostate-specific antigen (F/T-PSA) ratio can be used to differentiate between stage pT2 and pT3 prostate cancer. Material and Methods: A total of 176 consecutive patients from the Goteborg Screening Study (median T-PSA 4.2 ng/ml) who underwent radical prostatectomy (without neoadjuvant hormonal therapy) were included in the study. The pT stage was correlated with classical risk factors such as T-PSA and Gleason sum and the impact of the F/T-PSA ratio was evaluated. Results: A total of 42/176 patients (23.9%) had stage pT3 prostate cancer. Patients with an F/T-PSA ratio in the lowest quartile (<10.7%) had extracapsular tumor growth in 46.5% of cases, compared to 16.7% for those with an F/T-PSA ratio >10.7% ( p = 0.0002). Patients with high-risk features (T-PSA >10 ng/ml or Gleason sum greater than or equal to7) had a high risk (54-60%) for stage pT3 prostate cancer. In low-risk patients, the subgroup with an F/T-PSA ratio <10.7% had a risk of 37.0%, compared to only 13.3% for those with a ratio of >10.7% (p = 0.0092). Conclusions: In patients with low-risk early-stage prostate cancer, the F/T-PSA ratio provides statistically significant, independent and clinically relevant preoperative information about the risk of extracapsular tumor growth.

- OBJECTIVE: The aim of this study was to investigate the effects of a long series of electro-acupuncture (EAP) sessions on bedwetting symptoms. MATERIAL AND METHODS: Twenty-five children (age range 7-16 years) with monosymptomatic nocturnal enuresis and treated earlier without success were included in the study. The median number of wet nights per week was 4.7 before treatment. Bedwetting, voided volume, sleep and nocturia were evaluated 3 weeks, 3 months and 6 months after 20 sessions of EAP lasting 8 weeks. RESULTS: All the children, with the exception of one, tolerated EAP treatment well. At the three follow-up sessions it was found that the number of dry nights had increased gradually from a median of 2.3 in the pre-test to 3.0, 4.3 and 5.0 per week, respectively. Compared to pre-treatment findings there were more dry nights in 65% of the children (p < 0.001) and 5 out of 23 children were responders (> 90% reduction of the numbers of wet nights) at the 6 months' follow-up. According to the parents, the sleep arousal threshold had decreased in about 50% of the children.
