Triggers for transition from active surveillance to radical treatment of prostate cancer 2008-2020 - a case-control study.

OBJECTIVE: To examine associations between objective signs of progression (triggers) and transition from active surveillance (AS) to radical treatment for prostate cancer (PC). PATIENTS AND METHODS: This case-control study included men with low- or favourable intermediate-risk PC in the region of Halland, with data from The National Prostate Cancer Register (NPCR), Sweden, starting AS between 2008 and 2020. Cases were men who transitioned to radical treatment. For each case, 10 controls who remained in AS were selected without further matching. Triggers for transition to treatment were histopathological progression, magnetic resonance imaging (MRI) progression and increases in prostate-specific antigen (PSA) levels. We compared the probabilities for triggers between cases and controls, in 2008-2014 and 2015-2020, using logistic regression. RESULTS: Amongst 846 men, we identified 98 cases in 2008-2014 and 172 cases in 2015-2020. Histopathological progression was associated with transition, most strongly in the later period (2008-2014: odds ratios [OR] 6.88, 95% confidence interval [CI] 3.69-12.80; and 2015-2020: OR 75.29, 95% CI 39.60-143.17). MRI progression was associated with transition in 2015-2020 (OR 6.38, 95% CI 2.70-15.06), whereas an increase in PSA was weakly associated with transition in the early period. The absence of triggers was associated with no transition (2008-2014: OR 0.24, 95% CI 0.15-0.40, and 2015-2020: OR 0.09, 95% CI 0.06-0.14). The probability of no trigger was 27% in cases 2015-2020. CONCLUSION: The increase in association between histopathological trigger and transition to treatment indicates increased quality of AS. Still, amongst men treated from 2015 to 2020, 27% transitioned without any trigger.

Functional results after orthotopic bladder substitution: a prospective multicentre study comparing four types of neobladder.

OBJECTIVE: The aim of this study was to evaluate enterocystometry, voiding pattern and urine leakage of four types of orthotopic bladder substitute. MATERIAL AND METHODS: At eight urological departments, 78 consecutive men were studied: 66 with an ileal neobladder [30 Studer pouches (S), 24 Hautmann pouches (H) and 12 T-pouches (T)] and 12 with a right colonic [Goldwasser type (G)] neobladder. Enterocystometry, determination of residual urine, micturition protocol and 24 h pad weight test were performed 6 and 12 months postoperatively. RESULTS: Colonic neobladders had higher pouch pressure at first desire, normal desire and strong desire than ileal neobladders (except at first and normal desire at 12 months) (p < 0.02) and contraction was present more often at both 6 and 12 months (p < 0.01 and p < 0.01). Compliance was good in all types of pouch. Intermittent self-catheterization was more common in H patients at 6 months (p = 0.033). All patients with colonic neobladders used pads during the day and night. In patients with ileal pouches 32% used pads during the day and 70% during the night at 12 months. Urine leakage was higher in patients with colonic bladders at 6 and 12 months during the day (mean/median of 98/31 ml and 82/16 ml versus 10/0 ml and 4/0 ml, p < 0.001). T-pouches had excellent day-time continence, but nocturnal leakage was high. CONCLUSIONS: The Hautmann pouch and the Studer pouch behaved similarly at enterocystometry and clinically, and continence was good in the majority of patients. The low number of patients with the other two types of pouch precludes definitive statements.

Lower urinary tract symptoms: lack of change in prevalence and help-seeking behaviour in two population-based surveys of women in 1991 and 2007.

OBJECTIVES: To test the hypothesis that the overt prevalence and help-seeking pattern for lower urinary tract symptoms (LUTS) might have changed over time, by comparing the prevalence of urinary incontinence (UI), overactive bladder (OAB) and other LUTS (principally storage symptoms) and help-seeking pattern in two equivalent groups of women 16 years apart. SUBJECTS AND METHODS: We compared two cross-sectional studies; population-based random samples of women aged ≥20 years in the central district of Gothenburg in 1991 (2911) and 2007 (3158) were asked to complete similar self-administered postal questionnaires regarding UI and other LUTS. RESULTS: The mean (sd, range) age of the two groups was 48.1 (20.4, 20-98) years in 1991 and 46.2 (20.0, 20-101) years in 2007, respectively. When comparing the two study populations there were no significant differences in the reported prevalence of UI, OAB or nocturia (defined as two or more voids per night) over time. Nocturia according to the International Continence Society definition was significantly more prevalent in 2007 than 1991, as was daytime voiding frequency of eight or more times a day. OAB dry (i.e. with no incontinence) was more common in 1991, while OAB wet (i.e. with incontinence) was more prevalent in 2007. Of the women in 1991 and 2007, 6% and 7%, respectively, had sought help from the healthcare system due to UI. Significantly more women in 2007 than in 1991 stated that the presence of UI limited their social life (29% vs 13%, P < 0.001). CONCLUSION: LUTS are common in women and the prevalence rates of UI and OAB have not changed during the last 16 years. Many women still do not seek help from the healthcare system, and the help-seeking pattern has remained unchanged, despite effective treatment currently being offered.

A longitudinal population-based survey of urinary incontinence, overactive bladder, and other lower urinary tract symptoms in women.

BACKGROUND: Female urinary incontinence (UI), overactive bladder (OAB), and other lower urinary tract symptoms (LUTS) are highly prevalent conditions with a profound influence on well-being and quality of life. There are a few studies describing progression as well as remission, in the short term, of UI in the general population as well as in selected groups; at present, there are very few population-based studies describing the natural course of other LUTS in the same women, and there are no long-term longitudinal studies. OBJECTIVE: To describe the prevalence of UI, OAB, and other LUTS in the same women studied prospectively over time and, thus, to assess possible progression or regression. DESIGN, SETTING, AND PARTICIPANTS: A longitudinal population-based study was performed in one primary health care district in the city of Gothenburg, Sweden. The participants were a sample of women aged > or = 20 yr who were randomly selected from the Swedish National Population Register, assessed in 1991 (n=2911), and available for reassessment in 2007 (n=1408). METHODS: A self-administered postal questionnaire regarding UI, OAB, and other LUTS was returned by 77% of the contacted women in 1991. The same women who responded in 1991 and who were still alive and available in the Swedish National Population Register 16 yr later were reassessed using a similar self-administered postal questionnaire. RESULTS AND LIMITATIONS: In 2007, 1081 of the available 1408 women responded to the questionnaire (77%). The overall prevalence of UI, OAB, nocturia, and daytime micturition frequency of eight or more times per day increased by 13%, 9%, 20% (p<0.001), and 3% (p<0.05), respectively, from 1991 to 2007. The incidence of UI and OAB were 21% and 20%, respectively, and the corresponding remission rates were 34% and 43%, respectively. Women with OAB symptoms were classified as OAB dry or OAB wet, depending on the presence or absence of concomitant UI. The prevalence of OAB dry did not differ between the two assessment occasions (11% and 10%, respectively), but the prevalence of OAB wet increased from 6% to 16% (p<0.001). CONCLUSIONS: UI and other LUTS constitute dynamic conditions. In this study, there was a marked overall increase in the prevalence of UI, OAB, and nocturia in the same women from 1991 to 2007. Both incidence and remission of most symptoms were considerable.

Afferent intussuscepted antireflux nipple valve complications in the Kock pouch for continent urinary diversion Early results with a modified technique.

OBJECTIVES: To analyse the risk of afferent nipple valve stenosis and its consequences and management in patients with a Kock pouch for continent urinary diversion and to study the early results after using an alternative antireflux technique. MATERIAL AND METHODS: Sixty patients consecutively operated on with a conventional Kock reservoir for continent cutaneous urinary diversion between 1988 and 2001 were analysed with regard to the occurrence of afferent nipple valve stenosis and its clinical characteristics. Sixteen patients operated on for continent urinary diversion during the period 2002-04 had the antireflux valve constructed according to the serous-lined extramural ileal valve technique. RESULTS: Eight patients with a conventional Kock pouch developed true afferent nipple valve stenosis and the risk approached 30% after 15 years. Dilatation and stenting were usually successful. CONCLUSIONS: The high risk of afferent nipple valve stenosis when using the intussuscepted nipple valve in the construction of a Kock reservoir for continent cutaneous urinary diversion calls for an alternative method for anastomosing the ureters to the reservoir. Our early results with the combined Kock/T-pouch are promising.

Continent cutaneous urinary diversion is still a valid alternative after cystectomy for bladder carcinoma.

OBJECTIVE: We compared patient opinions concerning reservoir/bladder function as well as quality of life (QOL) after cystectomy for bladder carcinoma and continent cutaneous urinary diversion or orthotopic bladder reconstruction. MATERIAL AND METHODS: Fifteen patients with Kock reservoirs (11 females, 4 males) and 11 men with orthotopic bladders answered the European Organization for Research and Treatment of Cancer quality-of-life questionnaire-C30 as well as specially constructed questions concerning reservoir/bladder function. The glomerular filtration rate (GFR) was determined using Cr-EDTA or iohexol clearance. RESULTS: Functioning and global health/QOL scales did not differ between the two groups of operated patients or between diverted patients and gender- and age-matched groups from the general population. The majority of the patients were satisfied/very satisfied with their diversion but more patients were troubled by leakage in the orthotopic bladder group than in the Kock reservoir group. The GFR was similar in the two groups. CONCLUSION: Continent cutaneous urinary diversion is associated with fewer leakage problems than orthotopic bladder reconstruction after cystectomy for bladder carcinoma.

Stamey's abdominovaginal needle colposuspension for the correction of female genuine stress urinary incontinence--long-term results.

OBJECTIVES: To evaluate the long-term continence rate, subjective satisfaction and treatment-associated morbidity in a carefully selected group of patients undergoing Stamey bladder neck suspension. MATERIAL AND METHODS: We studied 24 women with objectively validated genuine stress urinary incontinence (GSI) who were treated using the Stamey needle colposuspension method. Follow-up was performed by means of a questionnaire, a urodynamic assessment and a new standardized quantification test. Time to follow-up ranged from 28 to 100 months (mean 63 months). RESULTS: Of the 24 patients, 20 (83%) reported an improvement in clinical symptoms for a mean of 37 (range 12-84) months at the evaluation and 10 (42%) were completely continent after the Stamey procedure. Four patients (17%) reported a poor outcome of the operation, but in only one case could this be related to recurrent GSI. Treatment-associated morbidity was low but the frequency of postoperative urgency symptoms was higher than that reported in other studies (21%). CONCLUSION: In a selected population of pure GSI patients with no demonstrable detrusor overactivity, the Stamey bladder neck suspension procedure appears a feasible therapeutic option with few complications.

Neurological signs are common in patients with urodynamically verified "idiopathic" bladder overactivity.

Overactive bladder dysfunction is an expression of defective neuromuscular control of the lower urinary tract. The causes and the way to classify this problem are currently under debate. In some patients the overactive bladder is one sign of a neurological disorder, in so called "idiopathic detrusor instability" the cause is less obvious. That an overactive bladder has a neurogenic cause is a reasonable hypothesis. We made a detailed neurological investigation in 45 patients with idiopathic overactive bladder. Cerebrospinal fluid (CSF) was examined and blood tests for vitamin B(12)and folic acid deficiency were checked, too. In 37 of the 45 patients (82%) pathological signs were observed in the neurological tests. The most common finding was central or peripheral paresis of the legs appearing in 24 patients (53%). Of the 45 patients, eight received a neurological diagnosis, definite or possible MS or dorsal column sensation neuropathy. The results of this study give an indication of the importance of the neurological examination and suggest that neuropathy might not be uncommon in patients with so-called idiopathic detrusor instability. This also invites to reconsideration of the current classification. It is possible that a new classification based on a functional view could provide a better fundament in the search of etiologic and pathogenetic factors and also guide in the selection of the treatment most optimal for the individual patient.
