Diagnostic accuracy of uroflowmetry parameters to predict infravesical obstruction / Exactitud diagnóstica de los parámetros de la flujometría para predecir la obstrucción infravesical

Objective: to evaluate the performance statistics of average flow (Qave), voiding time (Vtime), and time to maximum flow (TQmax), in addition to maximum flow (Qmax), for diagnosis of infravesical obstruction. Methods: we reviewed urodynamic studies performed in men > 40 years. Obstruction was considered a grade 3-6 in the Schäfer nomogram. Sensitivity, specificity, positive likelihood ratio (LR+), negative likelihood ratio (LR-), and the receiver operator characteristic (ROC) curve were calculated for the different components of free uroflowmetry. Results: we analyzed 432 studies. Patients with obstruction had lower values of Qmax and Qave, and higher values of Vtime and TQmax. Considering different thresholds, Qmax had sensitivity, specificity, LR + and LR- values of 12-83%, 50-97%, 1.7-4.46 and 0.32-0.9, respectively; Qave had sensitivity, specificity, LR + and LR- values of 65-95%, 21-66%, 1.22-1.94 and 0.19-0.53, respectively; Vtime had sensitivity, specificity, LR + and LR- values of 49-85%, 26-67%, 1.15-1.54, and 0.57-0.74, respectively; TQmax had a sensitivity, specificity, LR + and LR- of 36-81%, 22-72%, 1.04-1.33 and 0.85-0.87, respectively. The areas under the ROC curves for Qmax, Qave, Vtime and TQmax were 0.75 (95% CI = 0.71-0.79, p < 0.001), 0.71 (95% CI = 0.66-0.75, p < 0.001), 0.62 (95% CI = 0.57-0.67, p < 0.001) and 0.55 (95% CI = 0.5-0.6, p = 0.03), respectively. Conclusions: Qave, Vtime, and TQmax showed a statistically significant discriminatory capacity to predict infravesical obstruction, and therefore they have clinical value as a complement to the information provided by Qmax.

Objetivo: evaluar las estadísticas de desempeño del flujo promedio (Qave), el tiempo de evacuación (Vtime) y el tiempo hasta el flujo máximo (TQmax), además del flujo máximo (Qmax), para el diagnóstico de obstrucción infravesical. Métodos: revisamos urodinamias realizadas en hombres > 40 años. La obstrucción se consideró un grado 3-6 en el nomograma de Schäfer. Se calcularon la sensibilidad, la especificidad, la razón de verosimilitud positiva (LR +), la razón de verosimilitud negativa (LR-) y la curva característica operativa del receptor (ROC) para los diferentes componentes de la flujometría libre. Resultados: analizamos 443 estudios. Los pacientes con obstrucción tenían valores más bajos de Qmax y Qave, y valores más altos de Vtime y TQmax. Considerando diferentes umbrales, el Qmax tuvo valores de sensibilidad, especificidad, LR + y LR- de 12-83%, 50-97%, 1.7-4.46 y 0.32-0.9, respectivamente; Qave tuvo valores de sensibilidad, especificidad, LR + y LR- de 65-95%, 21-66%, 1.22-1.94 y 0.19-0.53, respectivamente; Vtime tuvo valores de sensibilidad, especificidad, LR + y LR- de 49-85%, 26-67%, 1.15-1.54 y 0.57-0.74, respectivamente; TQmax tuvo una sensibilidad, especificidad, LR + y LR- de 36-81%, 22-72%, 1.04-1.33 y 0.85-0.87, respectivamente. Las áreas bajo las curvas ROC para Qmax, Qave, Vtime y TQmax fueron 0,75 (95% CI = 0.71-0.79, p < 0,001), 0.71 (95% CI = 0.66-0.75, p < 0,001), 0.62 (95% CI = 0.57-0.67, p < 0,001) y 0.55 (95% CI = 0.5-0.6, p = 0.03), respectivamente. Conclusiones: Qave, Vtime y TQmax mostraron una capacidad discriminatoria estadísticamente significativa para predecir la obstrucción infravesical, por lo que tienen valor clínico como complemento de la información proporcionada por el Qmax.

Disfunción urinaria en la enfermedad de Parkinson: una revisión práctica / Urinary dysfunction in Parkinson's disease: a practical review

Resumen La enfermedad de Parkinson (EP) es una enfermedad multisistémica de naturaleza neurodegenerativa, que clínicamente se caracteriza por presencia de síntomas motores como bradicinesia, rigidez, temblor en reposo e inestabilidad postural. Sin embargo, también pueden estar presentes síntomas no motores que constituyen trastornos del ánimo, trastornos del sueño, disfunción cognitiva o disfunción autonómica. Dentro de las disfunciones autonómicas, los síntomas urinarios se han documentado en los pacientes con enfermedad de Parkinson. Los síntomas urinarios más comunes son la nicturia, urgencia urinaria, aumento de la frecuencia miccional e incontinencia de urgencia. El presente artículo hace una revisión narrativa de la literatura actual sobre los mecanismos fisiopatológicos, manifestaciones clínicas, diagnóstico y tratamiento de la disfunción urinaria en pacientes con enfermedad de Parkinson.

Parkinson's disease (PD) is a neurodegenerative multisystemic diseases, which is clinically characterized by the presence of motor symptoms such as bradykinesia, rigidity, resting tremor, and postural instability. However, non-motor symptoms constituting mood disorders, sleep disorders, cognitive dysfunction, or autonomic dysfunction may also be present. Within autonomic dysfunctions, urinary symptoms have been documented in patients with Parkinson's disease. The most common urinary symptoms are nocturia, urinary urgency, increased urinary frequency, and urge incontinence. This article makes a narrative review of the current literature on the pathophysiological mechanisms, clinical manifestations, diagnosis and treatment of urinary dysfunction in patients with Parkinson's disease.

Trastornos metabólicos urinarios en pacientes urolitiásicos con enfermedad renal poliquística y sin ella / Urinary metabolic disorders in urolithiasis patients with and without polycystic kidney disease

Introducción: La urolitiasis se ha incrementado en las últimas décadas. La enfermedad renal poliquística autosómica dominante (ERPAD), enfermedad renal hereditaria más frecuente, ocupa un lugar preponderante. Objetivos: Identificar la frecuencia de presentación de los trastornos metabólicos urinarios en pacientes litiásicos cubanos con ERPAD y sin ella Métodos: Estudio descriptivo, transversal. Fueron estudiados 579 pacientes adultos sin ERPAD, seleccionados por muestreo simple aleatorio y los 21 pacientes con ERPAD, del total de pacientes con litiasis urinaria que se realizó estudio metabólico renal en el Laboratorio de Fisiopatología Renal del Instituto de Nefrología, en el periodo 2010-2015. Los datos fueron tomados de la historia clínica y del informe de estudio metabólico renal. La información se procesó de forma automatizada (SPSS 22.0). Se utilizó el promedio, desviación estándar, análisis de distribución de frecuencias y el test de homogeneidad. Resultados: En los pacientes con ERPAD predominó el sexo femenino (57,1 por ciento), mientras que en los pacientes sin ERPAD, el masculino (63,4 por ciento). Los trastornos más frecuentes en la población no poliquística fueron hipercalciuria (45,3 por ciento) e hipofosfatemia (17,1 por ciento). En los poliquísticos, aclaramiento aumentado de ácido úrico (38,1 por ciento) e hipercalciuria (23,8 por ciento). Se encontraron diferencias estadísticamente significativas para aumento del aclaramiento de ácido úrico (p = 0,01) e hiperfosfatemia (p = 0,04). Conclusiones: Los principales trastornos metabólicos de los pacientes litiásicos, tanto poliquísticos como no poliquísticos, son el aclaramiento de ácido úrico aumentado, hipercalciuria, hiperuricosuria e hipofosfatemia, aunque el orden de presentación es diferente. El aclaramiento de ácido úrico aumentado y la hiperfosfatemia se presentan con mayor frecuencia en los pacientes litiásicos poliquísticos(AU)

Introduction: Urolithiasis has increased in recent decades. Autosomal dominant polycystic kidney disease (ADPKD), the most common of all hereditary kidney diseases, occupies a predominant position in terms of incidence. Objectives: Identify the frequency of occurrence of urinary metabolic disorders in Cuban urolithiasis patients with and without ADPKD. Methods: A descriptive cross-sectional study was conducted of 579 adult patients without ADPKD selected by simple random sampling, and 21 patients with ADPKD, from the total urolithiasis patients undergoing renal metabolic evaluation at the Renal Physiopathology Laboratory of the Institute of Nephrology in the period 2010-2015. Data were obtained from medical records and reports of renal metabolic studies. Information was processed with the statistical software SPSS version 22.0. Average and standard deviation were estimated and use was made of frequency distribution analysis and homogeneity testing. Results: A predominance was found of female sex among patients with ADPKD (57.1 percent) and male sex among patients without ADPKD (63.4 percent). The most common disorders were hypercalciuria (45.3 percent) and hypophosphatemia (17.1 percent) in the non-polycystic population, and increased uric acid clearance (38.1 percent) and hypercalciuria (23.8 percent) in polycystic patients. Statistically significant differences were found in uric acid clearance increase (p = 0.01) and hyperphosphatemia (p = 0.04). Conclusions: The main metabolic disorders of lithiasis patients, polycystic as well as non-polycystic, are increased uric acid clearance, hypercalciuria, hyperuricosuria and hypophosphatemia, with a varying order of presentation. Increased uric acid clearance and hyperphosphatemia are more common in polycystic lithiasis patients(AU)

Disfunción miccional en el adulto. Un artículo docente / Voiding dysfunction in the adult. A teaching article

Voiding dysfunction is defined as an abnormally slow and/or incomplete micturition, and can be divided in bladder outlet obstruction (BOO) and detrusor underactivity (or hypocontractility). BOO is characterized by reduced urine flow rate and increased detrusor pressure, and can be of anatomical or functional origin. Detrusor underactivity encompasses a reduced urine flow rate associated to low pressure and/or poorly sustained detrusor contraction, and its etiology is multifactorial. Lower urinary tract symptoms are classified as storage, voiding and post micturition symptoms, may be objectively quantified with specific questionnaires, and don't correlate properly with voiding dysfunction. Patients' evaluation requires a directed physical examination of the abdomen, pelvis and genitals focused to detect anatomical and neurological abnormalities. Voiding dysfunction can be demonstrated non-invasively using uroflowmetry and pelvic ultrasound. Uroflowmetry allows determining urinary flow characteristics and their most important parameters are voided volume, maximum flow rate and shape of the curve. Pelvic ultrasound permits to estimate prostatic size and post void residual, suspect detrusor hypertrophy (due to BOO) and detect bladder stones. Invasive test must be reserved for special cases of confirmed voiding dysfunction: cystoscopy when there is concomitant hematuria, urethrocystography to study urethral stenosis and urodynamics to differentiate BOO from detrusor underactivity.

Profile of sexuality and symptoms of lower urinary tract in non-institutionalized elderly

ABSTRACT Introduction: Urinary or sexual dysfunction in the elderly are underreported. However, they are highly prevalent. This study aims to identify the prevalence of these conditions. Objective: The aim is to carry out an investigation in non-institutionalized individuals over 60 years of age, to obtain data on its sexual and urinary health in São Paulo, Campinas, Santo André and Londrina. Results: 6.000 questionnaires were distributed, and 3425 were included in the study, for the analysis of the questionnaires separately. In relation to ADAM, 92% of the 1385 evaluated were suspicious of androgen deficiency (ADAM). As for the male sexual function, it was observed 37% of premature ejaculation. As for the female sexual function, 1300 (74%) did not practice sexual intercourse and the main reasons were: lack of partner and lack of sexual desire. In addition, 988 (78%) of women who had no sexual intercourse responded that they didn't want sex and, more importantly, about 22% of them would like to have sexual intercourse. International prostate symptom score (IPSS) showed gradual worsening of urinary symptoms with increasing age, being the most prevalent: nocturia and urinary urgency. As for the female IPSS, we noted that even after 80 years, the majority have mild symptoms related to voiding dysfunction; with increasing age there is a gradual increase in the result of the IPSS. Conclusion: Due to the large number of sexual and urinary disorders found, we recommend the improvement in health conditions, promoting a better quality of life in the elderly.

Assessment of the lower urinary tract symptoms after robotic-assisted radical prostatectomy: the behavior of voiding, storage and post micturition symptoms / Avaliação dos sintomas do trato urinário inferior após prostatectomia radical robótica-assistida: o comportamento dos sintomas de esvaziamento, armazenamento e pós-miccionais

ABSTRACT Introduction: despite being infrequent, urinary incontinence has a huge impact on the quality of life of patients undergoing radical prostatectomy, even with the robotic-assisted technique. Objective: to assess the evolution of urinary symptoms from preoperative to 12 months after robotic-assisted radical prostatectomy. Methods: data was collected from 998 patients who underwent robotic-assisted radical prostatectomy. Demographic data, preoperative and postoperative information on patients were documented. The ICIQ and IPSS questionnaires were also applied preoperatively and after 1, 3, 6 and 12 months after the operation. Results: Out of 998 patients, 257 correctly completed all questionnaires. The mean age of the patients was 60 ± 0.74 years. We found that the total IPSS increased initially and at 6 months after the operation, it was already lower than the initial preoperative value (7.76 at 6 months vs. 9.90 preoperative, p <0.001), being that questions regarding voiding symptoms were the first to improve followed by the questions regarding post micturition and storage symptoms. As for the ICIQ variables, there was an increase with radical prostatectomy and none of them returned to the preoperative level (p<0.001). Conclusions: robotic assisted radical prostatectomy causes, at first, a worsening of urinary symptoms in the lower tract with subsequent recovery. Recovery begins with voiding symptoms, followed by post micturition and storage symptoms. The symptoms assessed by the IPSS evolve to better parameters even than those of the preoperative period, while the symptoms of incontinence assessed by the ICIQ do not reach the preoperative levels in the studied interval.

RESUMO Introdução: apesar de infrequente, a incontinência urinária gera imenso impacto na qualidade de vida dos pacientes submetidos a prostatectomia radical, mesmo com a técnica robótica-assistida. Objetivo: avaliar a evolução dos sintomas urinários desde o pré-operatório até 12 meses após a prostatectomia radical robótica-assistida. Métodos: foram coletados os dados de 998 pacientes submetidos à prostatectomia radical robótica-assistida. Foram documentados dados demográficos, informações pré-operatórias e pós-operatórias dos pacientes. Também foram aplicados os questionários ICIQ e IPSS no pré-operatório e após 1, 3, 6 e 12 meses de pós-operatório. Resultados: de 998 pacientes, 257 preencheram corretamente todos os questionários. A idade média dos pacientes foi de 60±0,74 anos. Verificou-se que o IPSS total subia inicialmente e aos 6 meses após a operação, este já se tornava inferior ao valor inicial pré-operatório (7,76 aos 6 meses vs. 9,90 pré-operatório, p<0.001), sendo que as questões referentes a sintomas de esvaziamento foram as primeiras a melhorar e posteriormente as questões referentes a sintomas pós-miccionais e de armazenamento. Quanto às variáveis do ICIQ, houve elevação com a prostatectomia radical e nenhuma delas retornou ao patamar pré-operatório (p<0,001). Conclusões: a prostatectomia radical robótica assistida causa num primeiro momento uma piora nos sintomas urinários do trato inferior com uma recuperação subsequente. A recuperação se inicia pelos sintomas de esvaziamento, seguido dos sintomas pós-miccionais e de armazenamento. Os sintomas avaliados pelo IPSS acabam evoluindo a parâmetros melhores inclusive que os do pré-operatório, enquanto os sintomas de perda urinária avaliados pelo ICIQ não atingem os níveis pré-operatórios no intervalo estudado.

Urotherapy in the treatment of children and adolescents with bladder and bowel dysfunction: a systematic review / Uroterapia no tratamento de crianças e adolescentes com disfunção vesical e intestinal: revisão sistemática

ABSTRACT Objective: To identify and describe the protocols and clinical outcomes of urotherapy interventions in children and adolescents with bladder bowel dysfunction. Method: Systematic review carried out in June 2018 on Medical Literature Analysis and Retrieval System Online (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL),Excerpta Medica dataBASE (EMBASE), Scientific Electronic Library Online (SciELO), Cochrane Library, and PsycInfo databases. Clinical trials and quasi-experimental studies carried out in the last ten years in children and/or adolescents with bladder and bowel symptoms and application of at least one component of urotherapy were included. Results: Thirteen clinical trials and one quasi-experimental study were included, with moderate methodological quality. The heterogeneity of the samples and of the methodological design of the articles prevented the performance of a meta-analysis. The descriptive analysis through simple percentages showed symptom reduction and improvement of uroflowmetry parameters. The identified urotherapy components were: educational guidance, water intake, caffeine reduction, adequate voiding position, pelvic floor training, programmed urination, and constipation control/management. Conclusion: This review indicates positive results in terms of symptom reduction and uroflowmetry parameter improvement with standard urotherapy as the first line of treatment for children and adolescents with bladder bowel dysfunction. It is recommended that future studies bring contributions regarding the frequency, number, and time of urotherapy consultations.

RESUMO Objetivo: Identificar e descrever os protocolos e desfechos clínicos das intervenções de uroterapia em crianças e adolescentes com disfunção vesical e intestinal. Método: Revisão sistemática realizada em junho de 2018 nas bases Medical Literature Analysis and Retrieval System Online (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Excerpta Medica dataBASE (EMBASE), Scientific Electronic Library Online (SciELO), Cochrane Library e PsycInfo. Foram incluídos ensaios clínicos e estudos quase-experimentais dos últimos 10 anos, em crianças e/ou adolescentes com sintoma urinário e intestinal e aplicação de no mínimo um componente de uroterapia. Resultados: 13 ensaios clínicos e 1 estudo quase-experimental foram incluídos, sendo a qualidade metodológica moderada. A heterogeneidade da amostra e de delineamento metodológico dos artigos impediu a realização de meta-análise. A análise descritiva por meio de percentual simples demonstrou redução dos sintomas e melhora dos parâmetros de urofluxometria. Os componentes de uroterapia identificados foram: orientação educacional, ingestão hídrica, redução de cafeína, posicionamento adequado para eliminação, treinamento do assoalho pélvico, micção programada e controle/manejo da constipação. Conclusão: Esta revisão sinaliza resultados positivos em termos de redução de sintomas e melhora nos parâmetros de urofluxometria com aplicação de uroterapia padrão como primeira linha de tratamento nos casos de crianças e adolescentes com disfunção vesical e intestinal. Recomenda-se que estudos futuros tragam contribuições no que tange a frequência, número e tempo para as consultas de uroterapia.

Voiding symptoms obtained by open versus directed anamnesis as predictors of voiding dysfunction in women

ABSTRACT Objectives To determine the differences between voiding symptoms obtained by open anamnesis (VS-Open) versus voiding symptoms obtained by directed anamnesis (VS-Directed) to predict voiding dysfunction in women. Materials and Methods Retrospective study of women with prior anti-incontinence surgery evaluated during 5 years. In a standardized clinical history taking, each patient was asked to answer question number five of the UDI-6 questionnaire ("Do you experience any difficulty emptying your bladder?"). If the answer was positive, the following voiding symptoms spontaneously described by the patient were documented: slow urine stream, straining to void, intermittent stream and feeling of incomplete bladder emptying, which were considered VS-Open. If the answer to this question was negative or if the patient had not reported the four voiding symptoms, she was asked in a directed manner about the presence of each o Ninety-one women are analyzed. Eighteen patients presented voiding dysfunction (19.8%), There was a statistical association between voiding dysfunction and the presence of any VS-Open (p = 0.037) and straining to void obtained by open anamnesis (p = 0.013). Sensitivity, specificity, PPV, NPV, positive likelihood ratio and negative likelihood ratio, respectively, were 44.4% and 27.8%, 80.8% and 94.5%, 36.3% and 55.6%, 85.5% and 84.1%, 2.324 and 5.129, and 0.686 and 0.764. There was no statistical association between voiding dysfunction and VS-Directed. Conclusions VS-Open may predict better voiding dysfunction than VS-Directed in women.

Trastornos glomerulares en la práctica médica / Glomerulopathies in the medical practice

RESUMEN Las glomerulopatías agrupan varias nefropatías con lesiones fundamentalmente del corpúsculo renal y que se expresan principalmente por proteinuria, hematuria, edemas e hipertensión arterial. La presentación clínica varía en dependencia del tipo de enfermedad de que se trate. Constituye la causa más frecuente de enfermedad renal crónica en adultos jóvenes, por lo que su estudio resulta imprescindible sobre todo para el nivel primario de salud. El propósito fue actualizar consideraciones pertinentes sobre la conducta diagnóstica y terapéutica integral ante una glomerulopatía y valorar emisión de recomendaciones al respecto. Se realizó una búsqueda, análisis y síntesis de información a través de Bases de datos ScieLO Cuba, ScieLO regional, Pubmed, Cumed, Clinical Key en el período 2012-2017 con las palabras clave: síndrome nefrótico, glomerulonefritis, diagnóstico, terapéutica, atención integral. El abordaje en las glomerulopatías es integral, multidisciplinario e individualizado. En Cuba constituyen la cuarta causa de enfermedad renal crónica y predomina el síndrome nefrítico agudo postinfeccioso. El método clínico juega en ello un papel trascendental a la hora de reconocer y registrar sus aspectos clínicos, su etiología, su fisiopatología, y los exámenes complementarios que confirman su presencia o sus complicaciones, así como un tratamiento oportuno que garanticen el perfeccionamiento asistencial. El arma más poderosa ante el reto de los trastornos glomerulares es la visión integradora y con enfoque individual y social protagonizado por el médico ante este grupo de nefropatías en adultos.

ABSTRACT Glomerulopathies encompass a group of several renal disorders with lesions, mainly in the renal corpuscle, expressed in proteinuria, hematuria, edemas and arterial hypertension. Their clinical manifestations change in dependence of the kind of disease. They are the most frequent cause of chronic renal disease in young adults; therefore their study is very important above all in the health care primary level. The aim was updating pertinent considerations on the diagnostic behavior and comprehensive therapy in the case of glomerulopathy, and evaluating the emission of recommendations regarding to them. A search, analysis and synthesis of information was carried out in the databases ScieLO Cuba, ScieLO regional, Pubmed, Cumed, and Clinical Key in the period 2012-2017, using the key words nephrotic syndrome, glomerulonephritis, diagnosis, therapeutics, comprehensive care. The approach to glomerulopathies is comprehensive, multidisciplinary and individualized. They are the fourth cause of chronic renal disease; the acute post-infectious nephritic syndrome predominates. The clinical method plays a transcendental role at the moment of recognizing and registering their clinical characteristics, etiology and physiopathology, while complementary tests confirm their presence or complications, and therefore an opportune treatment guarantying the healthcare improvement. The most powerful weapon against the challenge of the glomerular disorders is the integrated vision with an individual and social approach led by the physician in the case of these nephropathies in adults.

Minimally invasive surgery improves short-term outcomes of nerve-sparing radical hysterectomy in patients with cervical cancer: a propensity-matched analysis with open abdominal surgery / 부인종양

OBJECTIVES: Nerve-sparing radical hysterectomy has been implemented in order to reduce pelvic floor dysfunctions in women undergoing radical surgery for cervical cancer. Here, we aimed to investigate if the adoption of laparoscopic surgery impacts on patients' outcomes. METHODS: Data of consecutive patients affected by cervical cancer who had laparoscopic nerve-sparing radical hysterectomy were matched 1:1 with an historical cohort of patients undergoing open procedure. A propensity-score matched algorithm was applied. RESULTS: Thirty-five patients' pairs (70 patients: 35 undergoing laparoscopic vs. 35 undergoing open abdominal nerve-sparing radical hysterectomy) were included. Demographic and baseline oncologic characteristics were balanced between groups. Patients undergoing laparoscopic surgery had similar operative time than patients undergoing open abdominal procedures (249 [±91.5] vs. 223 [±65.0] minutes; p=0.066). Laparoscopic approach correlated with lower blood loss (30.5 [±11.0] vs. 190 [90.4] mL; p < 0.001) and shorter hospital stay (3.2 [±1.2] vs. 5.4 [2.0] days; p=0.023). Patients undergoing laparoscopy experienced a lower 30-day pelvic floor dysfunction rate than patients having open surgery. Moreover, they experienced shorter recovery of bladder function than patients having open procedures (median, 7 vs. 9 days; p=0.004, log-rank test). CONCLUSIONS: Laparoscopic approach resulted in a faster recovery of bladder function in comparison to open surgery for patients undergoing nerve-sparing radical hysterectomy.

Influence of Urinary Dysfunction on Quality of Life in Women with Cervical Cancer after Radical Hysterectomy

PURPOSE: This study was conducted to identify the quality of life (QOL) and the influence of urinary dysfunction on QOL in women with cervical cancer after radical hysterectomy. METHODS: A secondary analysis was conducted using data collected for a previous study of Chun et al. and the same subjects of a group of 157 cervical cancer patients. Novel data from the EORTC QLQ-C30 and QLQ-CX24 were used in addition to the results of urinary dysfunction from the previous study. Descriptive analysis of EORTC QLQ-C30 and QLQ-CX24 results and a multiple regression analysis were conducted to explore the influence of urinary dysfunction on global QOL. RESULTS: Subjects showed low QOL especially for social, physical and role function in the EORTC QLQ-C30 as well as the QLQ-CX24. Intensity of urinary dysfunction (p<.001) as well as daily life distress due to urinary dysfunction (p<.001) were the most significant factors affecting QOL in women with cervical cancer after radical hysterectomy. CONCLUSION: Results suggest that oncology nurses should pay attention to the relatively low QOL of post-hysterectomy patients. They should also consider the influence of urinary dysfunction on QOL when developing nursing intervention programs to increase the QOL for women with cervical cancer after radical hysterectomy.

The patient had a palpable tumor in the hypogastrium and a low urinary obstructive syndrome. He was operated and a combined, transvesicular and retropubic adenomectomy was performed. The biopsy informed a little 3-4 points-Gleason, acinar, prostatic adenocarcinoma, in the context of a prostatic hyperplasia. The patient evolved satisfactorily and was followed up in consultation. The removed tumor was 736 g, and is the heaviest one reported in Cuba and the fifth worldwide (AU).

Benign prostatic hyperplasia

SUMMARY The minimally invasive procedures (mips) for the treatment of symptoms of benign prostatic hyperplasia (bph) are presented as attractive techniques due to their ease of accomplishment and the possibility of outpatient treatment. This guideline aims to present recommendations that may assist in decision making in patients with benign prostatic hyperplasia and indication of the different minimally invasive therapies. For this, a systematic review of the literature was performed, with the descriptors according to the pico: patient with benign prostatic hyperplasia, minimally invasive therapy, clinical outcome and adverse events. With no time restriction, in medline, cochrane central and lilacs databases via vhl, 1,007 papers were retrieved, of which 16 were selected to respond to clinical doubt. Details of the methodology and results of this guideline are set out in annex I

Is urotherapy alone as effective as a combination of urotherapy and biofeedback in children with dysfunctional voiding?

ABSTRACT Objective: To compare standard urotherapy with a combination of urotherapy and biofeedback sessions and to determine the changes that these therapies promote in children with dysfunctional voiding. Patients and Methods: The data of 45 patients who participated in the study from January 2010 to March 2013 were evaluated. All patients underwent urinary system ultrasonography to determine post-void residual urine volumes and urinary system anomalies. All patients were diagnosed using uroflowmetry - electromyography (EMG). The flow pattern, maximum flow rate, and urethral sphincter activity were evaluated in all patients using uroflowmetry - EMG. Each patient underwent standard urotherapy, and the results were recorded. Subsequently, biofeedback sessions were added for all patients, and the changes in the results were recorded and statistically compared. Results: A total of forty - five patients were included, of which 34 were female and 11 were male and the average age of the patients was 8.4 ± 2.44 years (range: 5 - 15 years). After the standard urotherapy plus biofeedback sessions, the post-void residual urine volumes, incontinence rates and infection rates of patients were significantly lower than those with the standard urotherapy (p < 0.05). A statistically significant improvement in voiding symptoms was observed after the addition of biofeedback sessions to the standard urotherapy compared with the standard urotherapy alone (p < 0.05). Conclusions: Our study showed that a combination of urotherapy and biofeedback was more effective in decreasing urinary incontinence rates, infection rates and post - void residual urine volumes in children with dysfunctional voiding than standard urotherapy alone, and it also showed that this combination therapy corrected voiding patterns significantly and objectively.

Predictors of Acute Postoperative Urinary Retention after Transvaginal Uterosacral Suspension Surgery

OBJECTIVES: To investigate the rate of postoperative urinary retention (POUR) and identify the risk factors for this complication in women who underwent transvaginal uterosacral suspension surgery. METHODS: A retrospective chart review was conducted for 75 women who underwent transvaginal uterosacral suspension surgery with vaginal hysterectomy, repair of cystocele, and levator myorrhaphy with/without transobturator anti-incontinence surgery. POUR was defined as a need for continuous intermittent catheterization on the third day subsequent to removal of the urethral indwelling catheter. RESULTS: Acute POUR was reported in 18 women (24.0%). Thirty-six of the 75 patients (48.0%) had undergone anti-incontinence surgery. Crude analysis revealed significant association between the following variables and the risk of POUR: hypertension, the lower average flow rate in the pressure-flow study (PFS), greater post-void residual (PVR) urine volume in PFS, and PVR >30% of the total bladder capacity (TBC) in PFS. In the logistic regression analysis, PVR >30% of the TBC in PFS was identified as the only significant predictor of POUR (odds ratio, 15.4; 95% confidence interval, 2.5–90.9; P = 0.003). CONCLUSIONS: The PVR >30% of the TBC in PFS was identified as the only predictive factor of acute POUR in women who underwent transvaginal uterosacral suspension surgery.

The Risk of Upper Urinary Tract Involvement in Patients With Ketamine-Associated Uropathy / 대한배뇨장애요실금학회지

PURPOSE: The aims of this study were to investigate the prevalence of upper tract involvement in ketamine-associated uropathy, and to determine the predictors of hydronephrosis in patients with a history of ketamine abuse. METHODS: This was a cross-sectional study of a prospective cohort of patients with ketamine-associated uropathy. Data including demographics, pattern of ketamine abuse, pelvic pain and urgency or frequency (PUF) symptom score, uroflowmetry (UFM) parameters, serum renal function, and liver function tests were collected. Upon consultation, ultrasonography was performed to assess the function of the urinary system. RESULTS: From December 2011 to October 2015, we treated 572 patients with ketamine-associated uropathy. Of these patients, 207 (36.2%) had managed to achieve abstinence at the time of their first consultation. Ninety-six patients (16.8%) in the cohort were found to have hydronephrosis on ultrasonography. Univariate analysis identified age, duration of ketamine abuse, PUF symptom score, voided volume on UFM, serum creatinine levels >100 μmol/L, and an abnormal serum liver enzyme profile as factors associated with hydronephrosis. Logistic regression revealed the following parameters to be statistically related to hydronephrosis: age (adjusted odds ratio [OR], 1.090; 95% confidence interval [CI], 1.020–1.166; P=0.012), functional bladder capacity (adjusted OR, 0.997; 95% CI, 0.995–0.999; P=0.029), serum creatinine >100 μmol/L (adjusted OR, 3.107; 95% CI, 1.238–7.794; P=0.016, and an abnormal serum liver enzyme profile (adjusted OR, 1.967; 95% CI, 1.213–3.187; P=0.006). CONCLUSIONS: Ketamine-associated uropathy can involve the upper urinary tract. Patient demographics as well as investigations of UFM, renal function tests, and liver function tests may allow us to identify at-risk patients.

Qualidade de vida, nível cognitivo e desempenho escolar em crianças portadoras de distúrbio funcional do trato urinário inferior / Quality of life, cognitive level and school performance in children with functional lower urinary tract dysfunction

Resumo Introdução: Distúrbios do Trato Urinário Inferior (DTUI) de causa funcional são disfunções vesicais sem defeitos anatômicos ou neurológicos. O diagnóstico é principalmente clínico, com sintomas padronizados pela International Children's Continence Society. Poucos estudos relacionam qualidade de vida destes pacientes ao nível cognitivo e aproveitamento escolar. Objetivos: Avaliar marcos do controle miccional, dificuldades cotidianas, qualidade de vida (QV), nível cognitivo e desempenho escolar de crianças portadoras de DTUI. Método: Série de casos de pacientes acompanhados na Nefrologia Pediátrica de hospital terciário com avaliação da QV (Pediatric Quality of Life Inventory - Peds-QL), Teste de Desempenho Escolar (TDE) e teste de matrizes progressivas de Raven. Resultados: Meninas de classe social menos favorecida foram 90,9% das crianças elegíveis. A média de idade foi 9,1 ± 4,8 anos. Os sintomas mais frequentes foram urge-incontinência (81%), manobras de contenção (77,3%) e enurese (59,1%) associados à síndrome do distúrbio de eliminações (63,6%). Cuidadores consideravam as perdas urinárias e/ou sintomas como voluntários, brigavam e/ ou batiam na criança. As crianças já tinham sido submetidas a situações constrangedoras e advertências de professores, escondiam sintomas e/ou roupas sujas. O escore médio de QV foi 71,0 ± 12,6 com menor média na dimensão escolar. No TDE 55% tiveram desempenho inferior e nas Matrizes de Raven 60% estavam intelectualmente em nível médio. Observaram-se escores menores de QV no nível médio e inferior do TDE e capacidade intelectual média/abaixo da média nas Matrizes de Raven. Conclusão: DTUI pode influenciar negativamente relações familiares e sociais, desempenho escolar e qualidade de vida das crianças portadoras.

Abstract Introduction: Lower urinary tract dysfunction (LUTD) are voiding dysfunctions without anatomical or neurological defects. The diagnosis is primarily clinical, with symptoms standardized by the International Children's Continence Society. Few studies relate quality of life of patients with cognitive and school performance. Objective: To evaluate milestones of bladder control, daily problems, quality of life (QoL), cognitive function and school performance of children with LUTD. Methods: Case series of patients followed in the Pediatric Nephrology tertiary hospital with assessment of QoL (Pediatric Quality of Life Inventory - PedsQoL version 4), School Performance Test (TDE) and Raven Progressive Matrices test. Results: Girls of lower social class were (90.9%) of eligible children. The mean age was 9.1 ± 4.8 years old. The most common symptoms were urge incontinence (81%), holding maneuvers (77.3%) and enuresis (59.1%) associated with the elimination disorder syndrome (63.6%). Caregivers considered volunteers urinary losses and/ or symptoms, and fought and/or beat the child. Children had been subjected to embarrassing situations such as warnings of teachers, they hid symptoms and/or the dirty clothes. Mean score of QoL was 71.0 ± 12.6 with the lowest mean score on the school dimension. In TDE 55% had lower performance and in Raven Matrices 60% were intellectually in the medium level. It was observed lower QoL scores in the medium and lower level of TDE and average intellectual capacity/below average in Raven matrices. Conclusion: LUTD may negatively affect family and social relationships, school performance and QoL of children with the dysfunction.
