Voiding dysfunction and detrusor instability after the colposuspension operation for genuine stress incontinence

Bombieri, Luigi January 1999 (has links)
Colposuspension is an effective treatment for genuine stress incontinence. Continence is restored by positioning the bladder neck in a fixed and elevated retro-pubic position. Despite a high success rate of up to 90%, post-operative complications occur which may have an adverse effect on quality of life. Voiding difficulties develop in 0-43% of patients and detrusor instability in 2- 25%. This considerable variability is due to differences in definition, the timing of assessment, patient selection, and probably also in surgical technique. The natural history of these complications is not clearly known due to the lack of prospective follow-up studies. There is also general uncertainty with regards to their causes. While retrospective studies have attempted to identify pre-operative risk factors, there are no prospective studies which attempt to correlate the anatomical and functional changes caused by surgery with the development of voiding dysfunction and detrusor instability. This study has investigated prospectively 77 women undergoing the operation of colposuspension in relation to the incidence, natural history and causes of post-operative voiding dysfunction and detrusor instability. The complications were identified and followed-up objectively by means of serial urodynamic studies. Patients were also assessed clinically and using quality of life measures. The development of complications were correlated to a number of anatomical and functional changes caused by surgery. Anatomical changes were identified mainly by imaging the bladder neck with Magnetic Resonance Imaging (MRI). Functional changes were identified using urodynamic studies. Voiding dysfunction after colposuspension was common, with 69% of women requiring a catheter for more than seven days, and 28% for longer than 14 days. Improvement occurred gradually in most cases, with only 7. 7% and 2.5% of them needing catheterization at three months and one year respectively. De novo detrusor instability occurred in 21% of women at three months follow-up, and was symptomatic in 66% of these cases. Objective and subjective resolution was seen in 50% of these at one year follow-up. Quality of life after colposuspension improved in most cases despite the development of these complications, probably due to the resolution of their incontinence. Voiding dysfunction and detrusor instability after colposuspension were found to be multifactorial, due to patient related factors (age and detrusor contractility for voiding dysfunction, and age and a past history of bladder neck surgery for detrusor instability), and to operative factors (amount of bladder neck elevation and urethral compression). These findings might lead to the development of preventative measures.

Semi-Automated Detection of Bladder Neck Funneling and Measurement of Posterior Urethrovesical Angle in Females

Vandermolen, Megan 29 April 2022 (has links)
The pathophysiology of stress urinary incontinence is poorly understood but bladder neck funneling (BNF) and posterior urethrovesical angle (PUVA) enlargement have been implicated. Methods to measure these phenomena are poorly established. The aim of this thesis was to develop and evaluate a semi-automated method to analyze BNF and PUVA from ultrasound images acquired transperineally and test its repeatability and concurrent validity compared to manual segmentation. Agreement between the semi-automated and manual methods was assessed by kappa statistics and intraclass correlation coefficients (ICCs). The repeatability of detection of BNF using the semi-automated approach was almost perfect (ĸC = 1.00 (p<0.001)), while the reliability of semi-automated detection of PUVA was good (ICC(3,1) = 0.860 (0.784 – 0.910)). Concurrent validity of BNF classification was almost perfect (ĸL = 1.00 (p<0.001)), while PUVA estimation was moderate (ICC(2,1) = 0.610 (0.514 – 0.705)). The method presented here is an acceptable proof of concept; further development is recommended.

Analysis of Long Term Prognosis and Efficacy of TURP in Taiwan

Chiang, Kwo-Tsao 01 September 2011 (has links)
BPH¡]Benign prostate hyperplasia¡^is one of the most common chronic diseases in aging male around the globe. TURP¡]Transurethral Resection of Prostate¡^remains the gold standard procedure of choice in BPH treatment. But limited literatures regarding the late complication of TURP was available. For understanding the long term follow up result after TURP, and predict the risk factors for re-intervention, we accessed the hospital claims for TURP from the National Health Insurance database, utilizing data from 2001 to 2007 , in 2001, 2002, 2003 TURP cases, we followed each cohort for 5 years to evaluate the late complications. We also examined the association between the characteristics of patient, hospital and the long term prognosis. In this study we found that from 2001to 2003, totally 1,225 patients under went TURP surgery, with the average age 71.52 ¡Ó 7.65 years (47-94 years). Among these cases, 140 patients (11.43%) experienced secondary surgery. Of the 140 secondary surgery patients, 71 received a secondary TURP, 35 received urethral stricture related surgery and 34 received bladder neck contracture related surgery. The study revealed both the characteristics of the patient and the hospital did not show significantly effect to the long term prognosis. In prediction the risk factors of the secondary surgery, the logistic regression analysis revealed those hospitals located at the central part of Taiwan compared to those at northern part of Taiwan showed a relative risk of 0.58, a significant trend of lower risk for secondary surgery. Otherwise, except this geographic location difference, other characteristics of the patient and the hospital show no significantly risk to the post-TURP second surgery. Conclusion of our study, the result of TURP surgery in Taiwan was fairly equal to that in advanced countries. Patient comorbidity, treated in different level, ownership hospitals resulted no significant difference in post-TURP prognosis.

Métodos: Foram avaliadas prospectivamente 140 mulheres continentes, divididas em quatro grupos de acordo com a faixa etária, G1 (n = 34) de 30 a 40 anos, G2 (n = 38) de 41 a 50 anos, G3 (n =35) de 51 a 60 anos e G4 (n= 33) acima de 60 anos. Os seguintes parâmetros foram avaliados: dados demográficos utilizando questionário clinico; hipermobilidade do colo vesical usando o teste do cotonete; trofismo vaginal com exame ginecológico; status hormonal da vagina com a colpocitologia; força muscular do AP, utilizando a perineometria e eletroneuromiografia (EMG). Resultados: Não houve diferença estatisticamente significativa entre a força muscular do AP, características demográficas, trofismo vaginal e hipermobilidade do colo vesical nos diferentes grupos (p>0,05). Foi encontrado um maior número de mulheres atróficas acima de 60 anos. Houve uma excelente concordância no trofismo vaginal avaliado pelo exame ginecológico e colpocitologia (Kappa = 0,888). Porém observamos que as mulheres com hipermobilidade apresentavam menor força muscular em relação às mulheres sem hipermobilidade na EMG. Conclusão: Apesar da atrofia vaginal ser maior nas mulheres acima de 60 anos , não observamos diferença na força muscular do AP durante o processo de envelhecimento fisiológico. Sendo assim, não podemos dizer que o trofismo é o único fator relacionado à força muscular do AP, dificultando a indicação de mulheres para profilaxia. Palavras - chave: continência urinária; força muscular; músculo assoalho pélvico; status hormonal; prolapso; hipermoblidade do colo vesical / Objectives: To assess the correlation between hormonal status and PF muscle strength. Methods: 140 continent women were prospectively evaluated, and divided into four groups according to age: G1 (n = 34) 30-40 years, G2 (n = 38) 41-50 years, G3 (n = 35) 51-60, and G4 (n = 33) older than 60 years. The following parameters were evaluated: demographic data using clinical questionnaire; hypermobility of the bladder neck using the swab test; vaginal trophism by gynecological examination; hormonal status of the vagina by cytology; muscle strength of the PF using perineometer and electromyography (EMG). Results: There was no statistical difference between PF muscle strength, demographic characteristics, vaginal trophism, and hypermobility of the bladder neck in the different groups (p > 0.05). There was a larger number of atrophic women among those over 60 years of age. Vaginal trophism assessed by physical examination was highly consistent with the findings of colpocytology (Kappa = 0.888). We found, however, that women with hypermobility by EMG had less muscle strength as compared to those with no hypermobility. Conclusion: Although vaginal atrophy is more intense in women older than 60 years, no difference was found in muscle strength of the PF during the physiological aging process. As a consequence, it is not possible to state that trophism is the only factor related to PF muscular strength, thus precluding the selection of women who should be referred to prophylaxis.

Étude comparative de la morphologie du plancher pelvien des femmes âgées continentes et avec incontinence urinaire

Pontbriand-Drolet, Stéphanie 04 1900 (has links)
But: Cette étude a pour but de comparer : a)la morphologie du plancher pelvien (PP), du col vésical et du sphincter urogénital strié (SUS) par IRM et b) la fonction du PP par palpation digitale (PERFECT scheme) chez les femmes âgées continentes ou avec incontinence urinaire à l’effort (IUE) et mixte (IUM). Méthode: Les femmes ont appris à contracter correctement leur PP et la fonction de leur PP a été évaluée. Une séance d’IRM dynamique 3T a suivi. Résultats: 66 femmes ont participé à l’étude. Les groupes étaient similaires en âge, IMC, nombre d’accouchements vaginaux et d’hystérectomie. La validité et la fidélité des différentes mesures anatomiques utilisées ont été confirmées au début de cette étude. Afin de contrôler l’effet potentiel de la taille du bassin sur les autres paramètres, les femmes ont été appariées par la longueur de leur inlet pelvien. Les femmes avec IUM ont un PP plus bas et un support des organes pelviens plus faible, selon leurs ligne M, angle LPC/Ligne H et hauteur de la jonction urétro-vésicale (UV). Les femmes avec IUE ont un PP similaire à celui des continentes, mais présentent plus d’ouverture du col vésical et un angle UV postérieur plus large au repos que les autres groupes. Il n’y a aucune différence de morphologie du SUS entre les groupes. De plus, selon les résultats du PERFECT scheme, les femmes avec IU ont une force du PP plus faible que les continentes. Les femmes avec IUM montrent aussi une faible élévation des muscles du PP à la contraction. Les femmes avec IUE ont, quant à elle, un problème de coordination à la toux. Conclusion: Les déficits causant l’IUE et l’IUM sont différents, mais supportent tous le rationnel des exercices du PP pour le traitement de l’IUE et l’IUM. Ces résultats supportent le besoin de traitements de rééducation spécifiques aux déficits de chacun des types d’IU. / Aims: The study’s aim was to compare: a) pelvic floor muscle (PFM), bladder neck and urethral sphincter morphologies using MRI and b) PFM function using digital palpation (PERFECT scheme) in continent women, women with stress (SUI) and mixed (MUI) urinary incontinence. Method: Women were taught how to perform PFM contractions correctly and their PFM function was assessed, then each woman completed a dynamic 3T MRI session. Results: 66 women participated in the study. Groups were similar for age, BMI, vaginal deliveries and hysterectomies. Validity and reliability of the different anatomical measures used has been confirmed at the beginning of the study. To control for the potential effect of pelvic size on study parameters, women were matched based on pelvic inlet length. MUI women seemed to have lower PFM resting position and pelvic organ support at rest, based on their M-Line, PCL/H-Line angle and urethrovesical (UV) junction height. However, SUI women seemed to have a PFM morphology similar to that of continent women, but presented a greater occurrence of bladder neck funnelling and a larger posterior UV angle. There were no differences in urethral sphincter morphology between the 3 groups. Functionally, as shown by the PERFECT scheme results, both UI groups had poorer PFM strength on MVC then continent women. The MUI group also showed poor PFM elevation on contraction. Conversely, women with SUI had a timing problem on cough. Conclusion: The deficits in women with SUI and MUI appear to be very different. Notwithstanding, they all support the rationale for PFM exercise treatment in older women with SUI and MUI. However, the findings suggest the need for rehabilitation treatments specificity for each UI type.
