Recomendaciones sobre el uso de las instilaciones endovesicales de ácido hialurónico en el síndrome de dolor vesical / Recommendations on the use of intravesical hyaluronic acid instillations in bladder pain syndrome

Introducción El síndrome del dolor vesical (SDV) es un síndrome complejo, sin etiología claramente establecida, que engloba diferentes entidades como la cistitis intersticial. Esto conlleva dificultades para establecer una definición precisa, obtener datos de prevalencia exactos y definir criterios diagnósticos y métodos estandarizados de estudio. Tampoco existe homogeneidad sobre el tratamiento del SDV. Las instilaciones endovesicales con ácido hialurónico (AH) son una opción, sin aún recomendaciones específicas.Objetivo Sintetizar la evidencia científica sobre las opciones terapéuticas disponibles para el SDV y consensuar un plan de trabajo y unas recomendaciones para el uso de las instilaciones endovesicales con AH.La Asociación Española de Urología, a través del Grupo de Urología Funcional, Femenina y Urodinámica, generó una comisión de expertos. Esta comisión fue la encarga de revisar la literatura (evidencia), consensuar el plan de trabajo y proponer recomendaciones.ResultadosExiste una gran variabilidad en la literatura sobre el tratamiento del SDV, sin un régimen estándar de instilación endovesical con AH (frecuencia y duración del tratamiento de inicio y mantenimiento).Conclusiones Las instilaciones endovesicales de AH (dosis habitual de 40mg) son efectivas y seguras. Pueden combinarse con otras opciones, siendo aún necesario comprobar la eficacia en algunos casos. El tratamiento se divide en varias sesiones iniciales semanales, seguidas de tratamiento de mantenimiento, generalmente mensual (duración de los ciclos no establecida).Se consensuaron recomendaciones sobre el manejo del SVD, con criterios diagnóstico y pautas para el tratamiento con AH endovesical (inicio, reevaluación y seguimiento) (AU)

Introduction Bladder pain syndrome (BPS) is a complex syndrome, without a clearly defined etiology that encompasses different entities, such as interstitial cystitis. This leads to difficulties in establishing a precise definition, obtaining accurate prevalence data, and defining diagnostic criteria and standardized assessment methods. Moreover, there is no consensus regarding the treatment of BPS. Intravesical instillations with hyaluronic acid (HA) are an option, although no specific recommendations have been made yet.Objective To synthesize the scientific evidence on the therapeutic options available for BPS and to establish a work plan and recommendations for the use of intravesical instillations with HA.The Spanish Association of Urology, through the Functional, Female, and Urodynamic Urology Group, created a commission of experts. This commission was in charge of reviewing literature (evidence), agreeing on the work plan, and proposing recommendations.ResultsThere is great variability in literature on the treatment of BPS, without a standard regimen of intravesical instillation with HA (frequency and duration of initial and maintenance treatment).Conclusions Intravesical HA instillations (usual dose of 40 mg) are effective and safe. They can be combined with other options, with efficacy still to be determined in some cases. Treatment is divided into several initial weekly sessions, followed by maintenance treatment, usually monthly (unestablished duration of cycles).Recommendations on the management of BPS were agreed, with diagnostic criteria and guidelines for treatment with intravesical HA (initiation, reassessment, and follow-up) (AU)

Recommendations on the use of intravesical hyaluronic acid instillations in bladder pain syndrome.

INTRODUCTION: Bladder pain syndrome (BPS) is a complex syndrome, without a clearly defined etiology that encompasses different entities, such as interstitial cystitis. This leads to difficulties in establishing a precise definition, obtaining accurate prevalence data, and defining diagnostic criteria and standardized assessment methods. Moreover, there is no consensus regarding the treatment of BPS. Intravesical instillations with hyaluronic acid (HA) are an option, although no specific recommendations have been made yet. OBJECTIVE: To synthesize the scientific evidence on the therapeutic options available for BPS and to establish a work plan and recommendations for the use of intravesical instillations with HA. The Spanish Association of Urology, through the Functional, Female, and Urodynamic Urology Group, created a commission of experts. This commission was in charge of reviewing literature (evidence), agreeing on the work plan, and proposing recommendations. RESULTS: There is great variability in literature on the treatment of BPS, without a standard regimen of intravesical instillation with HA (frequency and duration of initial and maintenance treatment). CONCLUSIONS: Intravesical HA instillations (usual dose of 40 mg) are effective and safe. They can be combined with other options, with efficacy still to be determined in some cases. Treatment is divided into several initial weekly sessions, followed by maintenance treatment, usually monthly (unestablished duration of cycles). Recommendations on the management of BPS were agreed, with diagnostic criteria and guidelines for treatment with intravesical HA (initiation, reassessment, and follow-up).

Bladder pain syndrome: Prevalence and routine clinical practice in women attending functional urology and urodynamics units in Spain. / Síndrome de dolor vesical: prevalencia y práctica clínica habitual en mujeres que acuden a Unidades de Urología Funcional y Urodinámica en España.

INTRODUCTION AND OBJECTIVES: Bladder pain syndrome (BPS) is classified as a rare chronic debilitating disease and its diagnosis presents a challenge because its symptoms overlap with those associated with overactive bladder syndrome. The aim of the routine study was to estimate the prevalence of BPS and discover to study the profile of symptoms and clinical practice for patients attending functional urology and urodynamics units. MATERIAL AND METHODS: An epidemiological study in which 37 functional urology and urodynamics units in Spain participated. The prevalence was studied in both sexes. Clinical practice was evaluated for 319 women with BPS (new diagnosis or under review). Clinical and sociodemographic data were collected retrospectively. The results were studied of urine tests, cystoscopy, biopsy, physical examination, bladder diary, and those of the four available questionnaires: Patient Perception of Bladder Condition; Bladder Pain/Interstitial Cystitis Symptom Score; EuroQoL-5 Dimensions-5L and Patient Global Impression of Severity. RESULTS: Five point four percent (503) of the patients who attended these units (9,312) had a diagnosis of BPS (90% [453] females). The tests that were performed most according to the clinical history and anamnesis were: urine test, bladder ultrasound and cystoscopy. The most common symptoms/comorbidities were: pain in the bladder region, increased urinary frequency, nocturia, anxiety and depression. Diagnostic assessment determined pain on hydrodistension (86.9%), positive biopsy (59.2%), myofascial pelvic pain (28.4%), urological phenotype (97.8%), and increased urinary frequency (88.7%). The questionnaires reflected how much the quality of life of these patients was affected. CONCLUSIONS: The prevalence of BPS in functional urology and urodynamics units in Spain is low. No homogeneity was observed in terms of diagnosis between the different participating centres. Therefore, a common methodology is required for the management of patients with BPS in these units, with tools specific to this disorder.

[Urodynamic evaluation of experimental bladder augmentation with seromuscular colocystoplasty]. / Evaluación urodinámica de ampliación vesical experimental mediante colocistoplastia.

INTRODUCTION: The use of de-epithelialized intestinal segment can avoid the complications associated of use to bowel segments for bladder augmentation. OBJECTIVE: We designed an experimental model New Zealand rabbit with previously reduced bladder capacity, and afterward we performed augmentation cystoplasty with urodynamics comparative effectiveness demucosalized and conventional colocystoplasty techniques. MATERIAL AND METHODS: In thirty-six male New Zealand rabbits fifty percent reduction cystoplasty was carried out. A month later the animals had bladder augmentation. They were randomly divided in two groups: 18 rabbits (group 1) underwent conventional colocystoplasty. In 18 rabbits (group 2) autoaugmentation procedure and demucosalized colocystoplasty was performed. All animals were sacrificed at 8 weeks of bladder augmentation. Urodynamics studies were practiced at beginning of each operation in all of them. RESULTS: Nine rabbits died and twenty-seven were evaluated: 14 rabbits group-1 and thirteen of group-2. The average increase in bladder capacity was 63% in group-1 under conventional colocystoplasty and 17% in group-2 demucosalized colocystoplasty. Average compliance improved to 141% in group-1 and 38% in group-2. CONCLUSIONS: In this study with "small bladder" New Zealand rabbit, the seromuscular colocystoplasty has poor urodynamics result in improving capacity and compliance bladder but conventional colocystoplasty has result effective.

[Clinical and analytical parameters that might indicate a second biopsy in patient with high PSA and previously negative biopsy]. / Parámetros clínicos y analíticos que indicarían la realización de una segunda biopsia en pacientes con PSAelevado y biopsia previa negativa.

OBJECTIVES: To determine what clinical, analytic and ultrasound parameters, are more effective to predict the result of a second biopsy in patient with high PSA and a first prostate biopsy negative. MATERIAL AND METHODS: It was carried out a longitudinal study in a series of 435 cases with negative prostate biopsy. In 59 of these cases it was practiced a second biopsy due to a permanent or sudden high PSA levels with or without a suspicious digital rectal examination. Of the 31 cases with a negative second biopsy, in 4 cases it was carried out a third biopsy. The biopsy was made in all the occasions by transrectal ultrasound guided sextant biopsy. It were also valued the ultrasound characteristic of the prostate, the prostate volume and the proportion of free PSA. RESULTS: It was demonstrated statistically significant differences among the patients with a second biopsy negative and positive regarding: the age, proportion of free PSA, abnormal digital rectal examination and presence of hipoechogenic areas in the prostate. The multivariate analysis demonstrated that the only significant parameters were the proportion of free PSA and the existence of an abnormal digital rectal examination. Based on the data of multivariate analysis, we settled down for the patients with normal digital rectal examination a cut-off point of 0.23 of proportion of free PSA as indication for the realization of a second biopsy, and of 0.59 for the patients with abnormal digital rectal examination. This protocol applied to our series would avoid the realization of a second biopsy in 8 patients, and a third biopsy in 1 patient, diagnosing all the cases of prostate cancer. CONCLUSIONS: The digital rectal examination associated with the proportion of free PSA constitutes a reliable parameter to indicate the realization of a second prostate biopsy in patient with high PSA and previous negative biopsy.

[Diagnostic algorithm based on a multivariate model to reduce the percentage of negative prostatic biopsies in patients with changed PSA or suspicious rectal palpation]. / Algoritmo diagnóstico basado en un modelo multivariante para reducir el porcentaje de biopsias prostáticas negativas en pacientes con PSA alterado o tacto rectal sospechoso.

OBJECTIVES: To determine what tests have a better diagnosis utility in patient with suspected prostate cancer due to PSA equal or greater than 4 ng/ml or abnormal digital rectal examination in order to reduce the number of negative prostate biopsies. MATERIAL AND METHODS: We carried out a ultrasound-guided sextant transrectal biopsy in a series of 400 patient with prostate-specific antigen (PSA) levels equal or greater than 4 ng/ml or abnormal digital rectal examination. All patients had also transrectal rectal ultrasonography to value the echographic prostatic characteristics and the prostatic volume, and a free PSA determination. RESULTS: The free/total PSA ratio (PSAl) and the PSA density (DPSA) were the most powerful predictors of prostate cancer, both with a 66% sensitivity and a 70% specificity (at a 0.15 cutoff), followed by the total PSA (PSAt), the digital rectal examination and the hypoechogenic prostatic nodules. We constructed a logistic multivariate model with these data. The outcome variable of logistic model was the probability of having prostate cancer. The significant predictive variables of the model were the PSAl, the DPSA, the digital rectal examination and the presence and extension of hypoechogenic prostatic. This model had a 81% sensitivity and 79% specificity at a 0.24 probability cutoff. We considered a 0.1 probability cutoff to reduce the number of false negative. With this strategy the sensitivity was 94% and the specificity 54%. If we had applied this model to the patient of our series then, we would be able to avoid prostate biopsy in 164 cases (the 41% of the patient), leaving only 7 cases without diagnosis of prostate cancer. CONCLUSIONS: The most effective combination parameters were the digital rectal examination, PSAl, presence and extension of prostatic hypoechogenic zones and DPSA. This combination allows us to diminish the percentage of negative prostate biopsy in patient with prostate-specific antigen (PSA) levels equal or greater than 4 ng/ml or abnormal digital rectal examination without significantly descending the number of detected prostate cancers.

[Urinary incontinence in menopause]. / Incontinencia urinaria en la menopausia.

OBJECTIVE: To determine if menopause increases the risk of developing bladder hyperactivity or stress urinary incontinence. METHODS: A case control study was conducted on 111 women, 57 with bladder hyperactivity and 54 controls without hyperactivity, and 55 cases with stress urinary incontinence and 55 controls without stress urinary incontinence. The results were analyzed by multivariant logistic regression for the influence of age. RESULTS: A relationship was found between age and menopause and the risk of developing stress urinary incontinence. No relationship was found between bladder hyperactivity and age or menopause. Age was found to be a negative factor of menopause in regard to the risk of developing stress urinary incontinence. CONCLUSIONS: The risk of developing stress urinary incontinence in menopausal women decreases with age and disappears after age 52.

Algoritmo diagnóstico basado en un modelo multivariante para reducir el porcentaje de biopsias prostáticas negativas en pacientes con psa alterado o tacto rectal sospechoso / Multivariate analysis based diagnosis algorithm for reducing the negative prostatic biopsies percentage in patients with elevated PSA level or abnormal digital rectal examination

OBJETIVOS: Determinar que pruebas tienen un mejor rendimiento diagnóstico en pacientes con sospecha de cáncer de próstata por PSA superior o igual a 4 ng/ml, o tacto rectal anormal, con el fin de disminuir el número de biopsias prostáticas negativas. MATERIAL Y MÉTODOS: Se realizó una biopsia transrectal ecodirigida en sextantes a una serie de 400 pacientes con PSA total superior o igual a 4 ng/ml, o tacto rectal sospechoso. En estos pacientes se valoró además las características ecográficas de la próstata, el volumen prostático y el PSA libre. RESULTADOS: Los parámetros de mayor rendimiento diagnóstico fueron la proporción de PSA libre (PSAl) y la densidad de PSA (DPSA), ambos con una sensibilidad del 66 por ciento y una especificidad del 70 por ciento (tomando como punto de corte óptimo un valor de 0,15), seguido del PSA total (PSAt), el tacto rectal y la presencia de zonas prostáticas hipoecoicas. Con estos datos se construyó un modelo logístico multivariante, siendo la variable resultado la probabilidad de presentar cáncer de próstata. Las variables predictivas significativas del modelo fueron el PSAl, la DPSA, el tacto rectal y la presencia y extensión de las zonas prostáticas hipoecoicas. Este modelo presentó una sensibilidad del 81 por ciento y una especificidad del 79 por ciento, tomando como punto de corte óptimo una probabilidad de padecer cáncer de próstata de 0,24. Con el fin de reducir el número de falsos negativos, se consideró como punto de corte del modelo una probabilidad del 0,1. Con este valor la sensibilidad fue del 94 por ciento y la especificidad del 54 por ciento. Si se hubiera aplicado este modelo al grupo de pacientes de nuestra serie se hubiera evitado la biop-sia en 164 casos (el 41 por ciento de los pacientes), dejándose sin diagnosticar únicamente 7 casos. CONCLUSIONES: La combinación de tacto rectal, PSAl, presencia y extensión de zonas hipoecoicas prostáticas y DPSA, permiten disminuir el porcentaje de biopsias en pacientes con PSAt superior o igual a 4 ng/ml, tacto rectal anormal, sin descender apreciablemente el número de cánceres de próstata detectados (AU)

[Toward a simplified method of classifying urinary incontinence in the elderly based on a multivariate analysis of 948 cases]. / Hacia un método simplificado de tipificación de la incontinencia urinaria del anciano, basado en el análisis multivariante de 948 casos.

OBJECTIVE: The present study analyzes the main clinical types of urinary incontinence in the elderly population and its clinical-urodynamic correlation to facilitate definitive diagnosis. METHODS/RESULTS: The study was conducted in 948 elderly patients (382 male, 566 female; mean age 72.4 years) with urinary incontinence. Patient clinical and urodynamic records were reviewed. The most common clinical types were urge-incontinence (56.4%) and incontinence with coughing associated with urge-incontinence (32.3%); the latter type was the most common in women. The most frequent urodynamic diagnoses were isolated bladder instability (29.9%), followed by obstruction (15.6%) and stress incontinence (14%). CONCLUSIONS: The most common symptom in bladder instability was urge-incontinence, while incontinence with coughing was found to be the most common symptom in urinary stress incontinence. A significant correlation was found between the postvoid residual urine and the main urodynamic diagnoses. Multivariate analysis showed that classification by clinical types of incontinence together with measurement of residual urine can facilitate diagnosis, although this approach has a low sensitivity for the main forms of isolated incontinence. The mixed forms require a urodynamic study.

[Diabetic neurocystopathy: multivariate study]. / La neurocistopatía diabética: estudio multivariante.

OBJECTIVE: To analyze the prevalence of urodynamic disorders and the factors associated with bladder instability in patients with diabetes mellitus. METHODS: We conducted a clinical and urodynamic study on 138 diabetic patients (71 males, 51%; 67 females, 49%) with a mean age of 64.04 years. Patient evaluation included patient history, neurological physical examination, cystometry, pressure-flow test, filling videocystography and selective EMG of the periurethral sphincter. Data obtained were analyzed by multivariant logistic regression analysis, taking the probability of developing bladder instability as a dependent variable. RESULTS: Bladder instability was the most frequent urodynamic finding (52%), followed by lower urinary tract obstruction (44%), involvement of bladder contractility (41%) and stress urinary incontinence (22%). Lower motor neuron (S2-S4) pudendal nerve lesion was observed in 33% of the cases and 24% had upper motor neuron involvement. Multivariant analysis showed age and stress urinary incontinence (inverse correlation) to be the only independent variables for bladder instability. The other variables that correlated with instability (but dependent on the foregoing variables) were involvement of bladder contractility and type of diabetes (higher probability for diabetes type II). No correlation was found for sex, duration of the diabetes, stroke (CVA), urinary obstruction or pudendal nerve lesion. CONCLUSIONS: Bladder instability was found to be the most frequent urodynamic disorder in diabetic patients. The probability of developing bladder instability increases with age and decreases in patients with stress urinary incontinence.

[Evidence-based medicine. Usefulness of isolated cystomanometry for the diagnosis of periurethral detrusor-sphincter dyssynergia in patients with suprasacral lesion]. / Medicina basada en la evidencia. Utilidad de la cistomanometría aislada para el diagnóstico de disinergia detrusor-esfínter periuretral en pacientes con lesión medular suprasacral.

OBJECTIVE: To determine the utility of cystomanometry alone in the diagnosis of periurethral detrusor-sphincter dyssynergia in patients with suprasacral spinal cord lesion. METHODS: Cystomanometry and selective electromyography were performed to evaluate the periurethral sphincter of 40 patients (16 female and 24 male; mean age 46.6 years) with suprasacral spinal cord injury diagnosed by neurological evaluation. RESULTS: The pre-test probability of having dyssynergia was 0.45. The post-test probability, with cystomanometrically demonstrated hyperreflexia, was 0.58. The likelihood ratio utilizing cystomanometry alone was 1.69. CONCLUSION: Cystomanometry alone is not useful in the diagnosis of periurethral detrusor-sphincter dyssynergia in patients with suprasacral spinal cord injury. Periurethral electromyography should be used in combination with the foregoing technique.

[Characterization of the DURR (dynamic urethral resistance relation] in the study of function lower urinary tract symptoms in the male]. / Caracterización del DURR (relación de resistencia uretral dinámica) en el estudio de los síntomas funcionales del tracto urinario inferior en el varón.

OBJECTIVES: To determine the type and to quantify the DURR phenomena in the male. METHODS: We conducted a clinical and urodynamic study in 31 male patients with functional lower urinary tract symptoms. RESULTS: DURR is produced by two types of mechanisms: urethral rigidity and contraction of the urethral wall. The patients with DURR produced by rigidity showed a higher score for irritative urinary symptoms. The patient with DURR produced by the contraction of the urethral wall had greater urodynamic consequences (increased opening pressure and PURR curve). The obstructive urinary symptoms were more intense when the DURR presented in the second phase of voiding (after reaching the maximum flow). CONCLUSIONS: The DURR phenomena have clinical and urodynamic consequences in males with functional lower urinary tract symptoms; therefore their type and quantity should be adequately determined.

[Value of the shape of the flowmetry curve in the study of prostatism]. / Valor de la morfología de la curva de la flujometría en el estudio del prostatismo.

OBJECTIVE: To determine the relation of the urinary flow curve morphology of free flowmetry with the status of lower urinary tract dynamics. METHODS: A mathematical model was designed to fit the urinary flow curves to two models: a symmetrical and an asymmetrical model. Based on these models we analyzed the relationship between the presence or absence of obstruction and the type of model which better adjusted the urinary flow curves in a series of 85 males. RESULTS: The urinary flow curves corresponding to absence of obstruction adjusted significantly better to a symmetrical model than those corresponding to bladder outlet obstruction. No correlation was observed between the type of curve and bladder contractibility or type of urinary obstruction. CONCLUSIONS: There is a relationship between the form of the urinary flow curve and bladder obstruction. In the absence of obstruction, the urinary flow curves are more symmetrical.

[A comparative study of different urodynamic methods used in the diagnosis of lower urinary tract obstruction in men]. / Estudio comparativo de los diferentes métodos urodinámicos utilizados en el diagnóstico de la obstrucción del tracto urinario inferior en el varón.

OBJECTIVES: The present study compared the results of the different urodynamic methods utilized in the diagnosis of urinary obstruction. METHODS: A urodynamic study was performed in 105 patients with prostatism; mean age 66.19 years. The following five urodynamic methods were utilized: maximum pressure/maximum flow rate (Pmax/Fmax), pressure/flow nomogram, pressure/flow curve, Schaefer's PURR and the resistance square. RESULTS: The Pmax/Fmax method showed the lowest percentage of obstruction (61%), 48% of the nomograms were inconclusive, the pressure/flow curve diagnosed obstruction in 88%, Schaefer's PURR diagnosed obstruction in 77% and the resistance square diagnosed obstruction in 78% of the cases. When the nomogram findings were diagnostic, no significant differences between the other methods were observed. The Pmax/Fmax, pressure/flow curve and the PURR methods proved to be independent methods, while the resistance square showed no significant differences with Schaefer's PURR. An irregular bladder at cystography was associated with a significantly higher percentage of obstruction (72% vs 92%). Lengthening and compression of the prostatic urethra demonstrable on cystourethrography was associated with the diagnosis of obstruction on all the methods used. A diminished segment of the urethral lumen was associated with a high percentage of obstruction on all methods, the PURR showing the highest (100%). However, the diagnosis of constrictive obstruction was found in only 30% of the cases.

[Clinical, urodynamic, and radiologic results in the study of prostatism with the PURR measure (passive urethral resistance ratio)]. / Resultados clínicos, urodinámicos, y radiológicos en el estudio del prostatismo mediante la medida de la PURR (relación de resistencia uretral pasiva).

OBJECTIVE: The present study was conducted to determine the correlation between the urinary symptoms and lower urinary tract dynamics in patients with prostatism. METHODS: 105 males with prostatism (mean 66.19 years) were evaluated clinically, urodynamically and radiologically by PURR (passive urethral resistance ratio) determination. RESULTS: The intensity of the irritative symptoms was slightly higher (21%) when bladder instability was associated. The obstructive symptoms were associated with diminished urinary flow rate and could be observed in bladder outlet obstruction (81%) or diminished bladder contractility (79%). Both conditions were found in 49% of the cases. The postvoiding urine depended on diminished bladder contractility (37%), but not on bladder outlet obstruction. Bladder instability did not depend on obstruction, although 88% of the patients with unstable bladder were obstructed. Compressive obstruction was associated with a lesser degree of diminished contractility (55%) than the other forms of obstruction. Prostatism was associated with diminished contractility without bladder outlet obstruction in 15% of the cases. The irregular bladder was more frequent in bladder outlet obstruction (92%) and bladder diverticula were more frequent in bladder instability (36%). In all the cases with compression and lengthening of the prostatic urethra, the diagnosis was compressive obstruction. In all the cases with segmental, diminished urethral diameter, the diagnosis was obstruction, although only 30% were diagnosed as constrictive compression. No pathological urethral changes were demonstrable on cystourethrography in 33% of the cases with obstruction. CONCLUSIONS: Urinary symptoms correlate poorly with lower urinary tract dynamics. PURR determination is a very reliable method of diagnosis in urinary obstruction, for both segmentally diminished and more extensive involvement (elongation and compression of the prostatic urethra) of the urethral lumen.

[Role of the bladder neck in urinary continence in women after urethropexy]. / Participación del cuello vesical en la continencia urinaria femenina posturetropexia.

We conducted a clinical, radiological and urodynamic study in 70 patients submitted to different urethropexy techniques (Kelly, Raz, Marshall-Marchetti-Krantz, Burch, simplified Ramírez) to determine the importance of the bladder neck in the treatment of urinary incontinence. Urethropexy achieved a significant increase in the percentage of patients with an open bladder neck during the filling phase. However, the opening of the bladder neck posturethropexy did not influence urinary continence.

[Infantile enuresis: epidemiologic, clinical, urodynamic, and radiologic data of a consecutive series of 100 cases]. / Enuresis infantil: datos epidemiológicos, clínicos, urodinámicos y radiológicos de una serie consecutiva de 100 casos.

The present paper reports the epidemiological, clinical, urodynamic and cystographic data of 100 consecutive patients (mean age 9.59 years) with nocturnal enuresis. These patients were divided into three groups: group I (4 to 7 years old), 23 patients; group II (8 to 11 years old), 51 patients; and group III (12 to 14 years old), 26 patients. Nocturnal enuresis was more frequent in group II (51%). It was more prevalent in males (51%) of groups I and II. Isolated nocturnal enuresis was more frequent (54%) than nocturnal enuresis associated with diurnal symptoms (46%) in all age groups. Urinary infection was observed in 16% and was more prevalent in girls (68.7%). Detrusor instability was the most common urodynamic finding (40%), particularly in group II and girls. Uncoordinated voiding was the second most common urodynamic finding (24%), particularly in group II and girls. Lower urinary tract infection was observed in 1% (males). No abnormal urodynamic data were observed in 19%. Neurogenic bladder was observed in 16%, mainly in group II (31%). Vesicoureteral reflux was detected in 18%, mainly in girls (66.6%) and a postvoiding residual urine in 10%. A diagnostic and prognostic system and a therapeutic strategy based on our data are proposed.
