Leiomioma parauretral en la postmenopausia reporte de un caso / Paraurethral leiomyoma in the postmenopause report of a case

El leiomioma parauretral es una patología poco frecuente, se trata de un tumor mesenquimatoso no dependiente de uretra y que ocasiona sintomatología uroginecológica en la paciente. Su manejo es principalmente quirúrgico. No se reportan casos de malignización, recidiva, ni metástasis y su diagnóstico diferencial se debe realizar con todas las patologías de masas uretrales y para-uretrales. El presente caso describe la presencia de este tumor en una mujer post-menopaúsica de 60 años, que además de presentar incontinencia urinaria mixta, refería signos obstructivos urinarios, fue diagnosticada y manejada de manera quirúrgica: Resección de tumor y posterior ubicación de cinta suburetral.

The paraurethral leiomyoma is a rare pathology, it is a mesenchymal tumor not dependent of the urethra which causes urogynecological symptoms in the patient. Its management is mainly surgical. No cases of malignancy, recurrence or metastasis are reported and its differential diagnosis must be performed with all pathologies of urethral and para-urethral masses. The present case describes the presence of this tumor in a 60-year-old post-menopausal woman who, in addition to presenting mixed urinary incontinence, referred obstructive urinary signs, was diagnosed and managed surgically: tumor resection and subsequent placement of suburethral tape.

Rol de onabotulinumtoxin A en el tratamiento de niños con vejiga neurogénica / The rol of Onabotulinumtoxin A in the treatment of children with a neurogenic bladder

Introducción: Onabotulinumtoxina es una alternativa terapéutica de segunda línea en pacientes sin respuesta a los anticolinérgicos. Objetivo: Evaluar los efectos de repetidas inyecciones de onabotulinumtoxina en vejigas neurogénicas refractarias al tratamiento clásico. Pacientes y métodos: Se evaluaron 82 pacientes menores de 18 años con vejiga neurogénica, en su mayoría por disrafia espinal. Todos fueron refractarios a oxibutinina oral. Si luego del tercer mes de la primer inyección en el detrusor se constataba mejoría clínica y/o urodinámica; se reinyectaban entre los 9 y 12 meses, nuevamente. De lo contrario, se indicaba cistoplastia de aumento. En algunos casos se utilizaron otros procedimientos endoscópicos - quirúrgicos accesorios. Resultados: Se reinyectaron con Onabotulinumtoxina, dos, tres, cuatro y cinco veces: 20 casos, 7, 4 y un caso, respectivamente. En el 51% promedio se logró continencia urinaria total (score cero-seco). En la primera y segunda inyección hubo incremento significativo en la media de capacidad cistométrica: de 254 a 331 ml (p: 0.007) y de 257 a 367 ml (p: 0.014); respectivamente. En algunos casos, luego de la primer inyección mejoró significativamente la compliance: de 6,9 a 11,4 ml/cmH2O (p: 0.05). La media de presión del detrusor al final del llenado disminuyó en promedio de 37 a 34,4 cmH2O. La sobreactividad del detrusor (n:22) se atenuó en el 54,4% luego de la primer inyección. No se registraron efectos adversos mayores con las reinyecciones. En 15 pacientes refractarios a OnabotulinumtoxinA se realizó ampliación vesical. Conclusión: Luego del tratamiento con onabotulinumtoxina, la continencia urinaria alcanzada fue del 50% promedio. La capacidad cistometrica se incrementó significativamente con las dos primeras inyecciones; aunque no se acompañó paralelamente de un importante descenso de presiones endovesicales. El uso de onabotulinumtoxina ha logrado suprimir o retrasar la clásica indicación de cistoplastia de aumento en niños refractarios a los anticolinérgicos (AU)

Introduction: OnabotulinumtoxinA is a second-line alternative therapy for patients who do not respond to anticholinergics. Aim: To evaluate the impact of repeated injections of OnabotulinumtoxinA in neurogenic bladders refractory to conventional treatment. Patients and methods: 82 patients younger than 18 years with a neurogenic bladder, in the majority due to spinal dysraphism, were evaluated. All were refractory to oral oxybutynin. If in the third month after the first injection in the detrusor clinical and/or urodynamic improvement was observed, between 9 and 12 months later a second injection was given. If not, augmentation cystoplasty was indicated. In some cases other endoscopic/surgical procedures were used. Results: Twenty, seven, four, and one case were reinjected with OnabotulinumtoxinA, two, three, four, and five times, respectively. In a mean of 51% of the patients total urinary continence was achieved (score zero - completely dry). On the first and second injection a significant increase of the maximum cystometric capacity was observed: from 254 to 331 ml (p: 0.007) and from 257 to 367 ml (p: 0.014), respectively. In some cases, after the first injection compliance improved significantly: from 6.9 to 11.4 ml/cmH2O (p: 0.05). Mean end filling detrusor pressure diminished from 37 to 34.4 cmH2O. Detrusor overactivity (n: 22) attenuated in 54.4% after the first injection. No major adverse effects were recorded after the reinjections. In 15 patients that were refractory to OnabotulinumtoxinA augmentation cystoplasty was performed. Conclusion: After OnabotulinumtoxinA treatment, 50% urinary continence was achieved. Cystometric capacity increased significantly after the first two injections; however, it was not associated with an important decrease of intravesical pressure. The use of OnabotulinumtoxinA may avoid or delay the classical indication of augmentation cystoplasty in anticholinergicrefractory children (AU)

The efficacy and safety of urethral injection therapy for urinary incontinence in women: a systematic review

To evaluate the efficacy and safety of different bulking agents for treating urinary incontinence in women, a systematic review including only randomized controlled trials was performed. The subjects were women with urinary incontinence. The primary outcomes were clinical and urodynamic parameters. The results were presented as a weighted mean difference for non-continuous variables and as relative risk for continuous variables, both with 95% confidence intervals. Initially, 942 studies were identified. However, only fourteen eligible trials fulfilled the prerequisites. Altogether, the review included 1814 patients in trials of eight different types of bulking agents, and all studies were described and analyzed. The measured outcomes were evaluated using a large variety of instruments. The most common complications of the bulking agents were urinary retention and urinary tract infection. Additionally, there were certain major complications, such as one case of death after use of autologous fat. However, the lack of adequate studies, the heterogeneous populations studied, the wide variety of materials used and the lack of long-term follow-up limit guidance of practice. To determine which substance is the most suitable, there is a need for more randomized clinical trials that compare existing bulking agents based on standardized clinical outcomes.

Associations between low back pain, urinary incontinence, and abdominal muscle recruitment as assessed via ultrasonography in the elderly

Background: Low back pain (LBP) and urinary incontinence (UI) are highly prevalent among elderly individuals. In young adults, changes in trunk muscle recruitment, as assessed via ultrasound imaging, may be associated with lumbar spine stability. Objective: To assess the associations between LBP, UI, and the pattern of transversus abdominis (TrA), internal (IO), and external oblique (EO) muscle recruitment in the elderly as evaluated by ultrasound imaging. Method: Fifty-four elderly individuals (mean age: 72±5.2 years) who complained of LBP and/or UI as assessed by the McGill Pain Questionnaire, Incontinence Questionnaire-Short Form, and ultrasound imaging were included in the study. The statistical analysis comprised a multiple linear regression model, and a p-value <0.05 was considered significant. Results: The regression models for the TrA, IO, and EO muscle thickness levels explained 2.0% (R2=0.02; F=0.47; p=0.628), 10.6% (R2=0.106; F=3.03; p=0.057), and 10.1% (R2=0.101; F=2.70; p=0.077) of the variability, respectively. None of the regression models developed for the abdominal muscles exhibited statistical significance. A significant and negative association (p=0.018; β=-0.0343) was observed only between UI and IO recruitment. Conclusion: These results suggest that age-related factors may have interfered with the findings of the study, thus emphasizing the need to perform ultrasound imaging-based studies to measure abdominal muscle recruitment in the elderly. .

Introducción: Alrededor del 16% al 45% de los adultos tiene síntomas de vejiga hiperactiva, que se manifiestan con urgencia para orinar, aumento en la frecuencia de micciones o incontinencia urinaria de urgencia, o ambos, denominado síndrome de vejiga hiperactiva. Los fármacos anticolinérgicos son los tratamientos más comunes para el tratamiento farmacológico y entre ellos la oxibutinina y la tolterodina. Esta evaluación tecnológica se desarrolló en el marco de la actualización integral del Plan Obligatorio de Salud para el año 2015. Objetivo: evaluar la efectividad y seguridad de la oxibutinina o la tolterodina para la incontinencia urinaria, comparadas con otros medicamentos antimuscarínicos como: solifenacina, darifenacina, fesoterodina para informar la toma de decisiones. Metodología: la evaluación fue realizada de acuerdo al protocolo definido previamente por el grupo desarrollador. Se realizó una búsqueda sistemática en MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects y LILACS, sin restricciones de idioma y limitada a revisiones sistemáticas publicadas en los últimos cinco años. Las búsquedas electrónicas fueron hechas entre octubre y noviembre de 2014 y se complementaron mediante búsqueda manual en bola de nieve y una consulta con expertos temáticos. La tamización de referencias se realizó por dos revisores de forma independiente y los desacuerdos fueron resueltos por consenso. La selección de estudios fue realizada mediante la revisión en texto completo de las referencias preseleccionadas, verificando los criterios de elegibilidad. La calidad de los estudios fue valorada con la herramienta AMSTAR. Las características de los estudios fueron extraídas a partir de las publicaciones originales. Se realizó una síntesis narrativa de las estimaciones del efecto para las comparaciones y desenlaces de interés a partir de los estudios de mejor calidad con AMSTAR. Resultados: se seleccionó una revisión sistemática que incluyó un total de 86 ensayos clínicos (31,249 pacientes) con medicamentos muscarínicos incluyendo a la Oxibutinina y la Tolterodina. Se realizaron comparaciones directas entre medicamentos y comparaciones intratecnología (dosis y presentaciones). Cuando se comparó la Tolterodina versus la Oxibutinina, no se encontró diferencia estadisticamente significativa en los desenlaces de calidad de vida, la percepción de cura o mejora y cuantificación de los síntomas. Cuando se comparó solifenacina versus tolterodina, se encontró diferencia estadisticamente significativa en los mismos desenlaces a favor de la solifenacina, e igual se reportó en la comparación fesoterodina versus tolterodina, a favor de la fesoterodina. Respecto a seguridad se comparó tolterodina versus oxibutinina y el retiro por eventos adversos fue más frecuente en el grupo de la oxibutinina RR 0.52 IC95% 0.40 a 0.66. En la comparación de soliferacina versus oxibutinina el retiro por eventos adversos fue más frecuente en el grupo de oxibutinina RR 0.45 IC95% 0.22 a 0.91 y al comparar la fesoterodina versus la tolterodina el retiro por eventos adversos fue más frecuente en el grupo de la fesoterodina RR 1.45 IC95% 1.07 a 1.98. Conclusiones: Efectividad: No se evidenció diferencia en efectividad entre la Oxibutinina y Tolterodina en los desenlaces de calidad de vida y la percepción de cura o mejora. Para la comparación de efectividad entre Oxibutinina versus Darifenacina y Solifenacina, no se reportaron resultados.

Polyacrylamide Hydrogel (Bulkamid) in Female Patients of 80 or More Years with Urinary Incontinence

Introduction: To assess the effectiveness of polyacrylamide hydrogel (Bulkamid ®) in injection therapy for urinary incontinence in women of 80 or more years. Materials and Methods: Twenty consecutive women mean age 84.5 (range 80-87) with stress or mixed urinary incontinence were enrolled in this prospective study. All subjects were evaluated at baseline and re-evaluated 7 days, 6,12,18 and 24 months after treatment. A detailed clinical evaluation, physical examination, daily pad count, urodynamic investigation and evaluation of urethral mobility by trans-labial ultrasound were performed. Results: A statistically significant decrease in the number of pads was observed in the follow-up (p = 0.0002 after 24 months). Physical examination showed a statistically significant lack or reduced lost of urine with stress test (p = 0.0163 after 24 months). Urodynamic findings showed an increase of Valsalva leak point pressure, maximum urethral closure pressure and functional length. Maximum flow and post void residual were respectively observed to be significantly reduced and increased only after 7 days from injection therapy. Quality of life (QoL) assessed with the Incontinence Impact questionnaire short form (IIQ-7) showed a statistically significant improvement (p = 0.0001 after 24 months). Patient satisfaction assessed with the Visual Analogue Scale and Patient Global Impression of Improvement questionnaire respectively produced evaluation of “satisfied” and “much improved” even after 24 months. Conclusions: Polyacrylamide hydrogel (Bulkamid®) is an effective treatment with low morbility in patients of 80 or more years. .

Botulinum toxin A in the treatment of spinal cord injury patients with refractory neurogenic detrusor overactivity

PURPOSE: To evaluate the efficacy of botulinum toxin type A injections in the detrusor muscle in patients with spinal cord injury and urinary incontinence due to detrusor overactivity and refractory to anticholinergic agents. MATERIALS AND METHODS: We prospectively evaluated 22 patients with spinal cord injuries, whose bladders were emptied by intermittent catheterization. All patients had detrusor overactivity and urinary incontinence that proved difficult to treat, despite using high doses of two different anticholinergics. The pre-treatment assessment included a complete urodynamic study and ultrasonography of the kidneys and urinary tract. A one-month follow-up was completed with urodynamic evaluation and the clinical response was evaluated through outpatient consultations and telephone contact. RESULTS: After the procedure, the maximum cystometric capacity and the bladder reflex volume increased, whereas the maximum detrusor pressure and compliance decreased. The mean duration of continence was 7 ± 7 months. In 18 patients (81.8 percent), it was necessary to administer anticholinergics to achieve continence. Five patients (22.7 percent) had indication of reinjection, and augmentation cystoplasty was indicated in 9 patients (40.9 percent). CONCLUSION: The use of botulinum toxin in the treatment of neurogenic detrusor overactivity refractory to anticholinergics is an option before more invasive treatments, such as augmentation cystoplasty, are attempted. In our study as well as in the literature, there was improvement in most urodynamic parameters. Overall, 40.9 percent of patients underwent augmentation cystoplasty and 81.8 percent of patients needed anticholinergic agents to reach urinary continence. Further studies are necessary to improve the procedure and to achieve better clinical results.

Terapia estrogênica no climatério: qual a melhor via? Uma resposta baseada nas melhores evidências / Estrogen therapy in climacteric: what is the best route? An answer based on the best evidences

Foi realizada uma pesquisa abrangente acerca de revisões sistemáticas, trabalhos randomizados e controlados, utilizando o banco de dados, Medline, Pubmed, Scielo e Biblioteca Cochrane com descritores apropriados para avaliar os efeitos das diferentes vias de administração dos estrogênios nas principais indicações da terapia estrogênica para o controle dos sintomas atribuídos à deficiência estrogênica do climatério (sintomas vasomotores e atrofia urogenital). Concluiu-se que, para os sintomas vasomotores, a administração de estrogênios pelas vias oral ou não-oral são eficientes. No caso da atrofia urogenital, a administração de estrogênios pela via vaginal parece ser mais eficaz do que a sistêmica

To evaluate the influence of different forms of estrogens delivery on the primary indication of estrogen therapy in postmenopausal women for the control of symptoms attributed to estrogen deficiency (vasomotor symptoms and urogenital atrophy) a comprehensive literature search was conducted using the database Medline, Pubmed, Scielo and Cochrane Library with appropriate key words for systematic reviews and controlled randomized trials on the subjects. It was concluded that, for vasomotor symptoms, oral or non-oral routes of estrogens administrations are safe and effective, and for urogenital atrophy, the vaginal route has showed to be better than systemic route

Experience with different botulinum toxins for the treatment of refractory neurogenic detrusor overactivity

Purpose: To report our experience with the use of the botulinum toxin-A (BoNT/A) formulations Botox® and Prosigne® in the treatment of neurogenic detrusor overactivity (NDO). Materials and methods: At a single institution, 45 consecutive patients with refractory urinary incontinence due to NDO received a single intradetrusor (excluding the trigone) treatment with botulinum toxin type A 200 or 300 units. Botox was used for the first 22 patients, and Prosigne for the subsequent 23 patients. Evaluations at baseline and week 12 included assessment of continence and urodynamics. Safety evaluations included monitoring of vital signs, hematuria during the procedure, hospital stay, and spontaneous adverse event reports. Results: A total of 42 patients were evaluated (74 percent male; mean age, 34.8 years). Significant improvements from baseline in maximum cystometric capacity (MCC), maximum detrusor pressure during bladder contraction, and compliance were observed in both groups (P < 0.05). Improvement in MCC was significantly greater with Botox versus Prosigne (+103.3 percent vs. +42.2 percent; P = 0.019). Continence was achieved by week 12 in 16 Botox recipients (76.2 percent) and 10 Prosigne recipients (47.6 percent; P = 0.057). No severe adverse events were observed. Mild adverse events included 2 cases of transient hematuria on the first postoperative day (no specific treatment required), and 3 cases of afebrile urinary tract infection. Conclusions: Botox and Prosigne produce distinct effects in patients with NDO, with a greater increase in MCC with Botox. Further evaluation will be required to assess differences between these formulations.

Urinary symptoms and quality of life changes in Thai women with overactive bladder after tolterodine treatment.

OBJECTIVES: To study the urinary symptoms and quality of life changes in Thai women with overactive bladder (OAB) after tolterodine treatment. MATERIAL AND METHOD: Thirty women (aged 30-77 years) diagnosed as having OAB at the Gynecology Clinic, King Chulalongkorn Memorial Hospital from January to April 2004 were included in the present study. Tolterodine 2 mg, twice daily was given. After 8 weeks treatment, changes in micturition diary variables and tolerability were determined. Short form 36 (SF36) questionaires (Thai version) were given before and after 8 weeks of treatment. RESULTS: At 8 weeks, all micturition per day decreased from 16. 7 +/- 5. 3 to 6. 7 +/- 2.4 times per day. The number of nocturia episodes decreased from 5.4 +/- 4.2 to 1.1 +/- 1.0 times per night. The most common side effect was dry month in 5 cases (16.7%) with 2 cases reporting a moderate degree and 1 case with severe degree. Only one case (3.3%) withdrew from the present study due to a severe dry mouth. The SF-36 scores changed significantly in the domains of physical functioning, role function emotional, social function and mental heath. CONCLUSION: Tolterodine was well tolerated and its effects improved the quality of life in Thai women with OAB.

Validação do questionário de qualidade de vida (King's Health Questionnaire) em mulheres brasileiras com incontinência urinária / Validation of a quality of life questionnaire (King's Health Questionnaire) in Brazilian women with urinary incontinence

OBJETIVO: a proposta deste estudo foi traduzir e validar o King's Health Questionnaire (KHQ) para mulheres brasileiras com incontinência urinária. MÉTODOS: 134 pacientes com incontinência urinária, confirmada pelo estudo urodinâmico, foram recrutadas em ambulatório de Uroginecologia. Inicialmente, traduzimos o questionário KHQ para a língua portuguesa (do Brasil) de acordo com critérios internacionais. Devido às diferenças da língua, fizemos a adaptação cultural, estrutural, conceitual e semântica do KHQ, para que as pacientes compreendessem as questões. Todas as pacientes responderam duas vezes o KHQ, no mesmo dia, com dois entrevistadores distintos, com intervalo de 30 minutos de uma entrevista para a outra. Depois de 7 a 14 dias, a aplicação do questionário foi repetida numa segunda visita. Foram testadas a confiabilidade (consistência interna intra e inter-observador) e validade do constructo e discriminativa. RESULTADOS: foram necessárias várias adaptações culturais até obtermos a versão final. A consistência interna intra-observador (alfa de Cronbach) das diversas dimensões oscilou de moderada a alta (0,77-0,90) e a consistência interna inter-observador oscilou de 0,66 a 0,94. Na validação do constructo, obtivemos correlação de moderada a forte entre os domínios específicos para incontinência urinária e manifestações clínicas que, sabidamente, afetam a qualidade de vida dessas pacientes. CONCLUSÃO: o KHQ foi adaptado ao idioma português e para a cultura brasileira, mostrando grande confiabilidade e validade, devendo ser incluído e utilizado em qualquer estudo brasileiro de incontinência urinária.

Gabapentin for overactive bladder and nocturia after anticholinergic failure

INTRODUCTION: We reviewed our experience with the use of gabapentin to treat symptoms of overactive bladder (OAB) and nocturia in patients who have failed conventional anticholinergic therapy. METHODS: Thirty-one patients referred to us with refractory (OAB) and/or nocturia were treated with oral gabapentin. All the patients had tried or remained on antimuscarinic drugs during treatment. Twenty-four of 31 complained of bothersome symptoms during day and night and the other seven had primary complaints of nocturia. Initial gabapentin doses ranged from 100-300 mg at bedtime. Dose was slowly titrated up to 3,000 mg based on patients' symptomatology and tolerability. RESULTS:The mean age was 51 years old (range 27-78). There were 13 men and 18 women. The median steady state dose chosen by the patient after initial titration was 600 mg/day. Fourteen of 31 patients reported subjective improvement of their frequency and 8 have been on the medication for over 12 months with persistent efficacy. For the 14 improved patients, mean frequency/24 hours decreased from 14.1 ± 2.2 to10.0 + 2.1. Three patients with primary nocturia reported improvement from a mean of 4.0 ± 1.3 to 1.0 ± 0.3 episodes/night. Six patients stopped taking the drug within one month due to side effects mostly described as drowsiness or lethargy. CONCLUSION: Fourteen of 31 patients with refractory (OAB) and nocturia improved with oral gabapentin. Gabapentin was generally well tolerated and can be considered in selective patients when conventional modalities have failed.

Resiniferatoxin for detrusor instability refractory to anticholinergics

PURPOSE: We have evaluated the clinical and urodynamic effects of intravesical instillation of resiniferatoxin in patients with idiopathic detrusor instability refractory to anticholinergics. MATERIALS AND METHODS: There were 30 women, median age 56 years old with detrusor instability for over 6 months and a history of anticholinergic use with no response or intolerable collateral effects. A 50 nM solution of resiniferatoxin was prepared for intravesical instillation. All patients were evaluated for urinary symptoms, as well as for urodynamic assessments before and 30 days after instillation. Tolerability was analyzed during the instillation. RESULTS: A clinical improvement was observed in 30 percent of the patients with urinary urgency and in 33 percent of the patients with urge-incontinence. The mean maximum cystometric capacity before application was 303.9 ± 78.9 and after application 341 ± 84.6. No significant difference was observed (p = 0.585). The mean maximum amplitude of the contractions diminished from 47.86 ± 29.64 to 38.72 ± 30.77 (p = 0.002). CONCLUSIONS: Resiniferatoxin, in this concentration, proved to be useful in a small percentage of patients regarding clinical detrusor instability. Maximum amplitude of the involuntary contractions was significantly reduced and in 33 percent patients the involuntary contractions disappeared. Further studies with different concentrations are recommended.

Efectos del valerato de estradiol ciproterona sobre el síndrome climaterio y parámetros bioquímicos en mujeres chilenas / Effects of estradiol valerate and ciproterone acetate on climateric syndrome and biochemical parameters in Chilean women

La menopausia se asocia a un demostrado aumento del riesgo de enfermedad cardiovascular y de osteoporosis, lo que justifica el uso de terapia hormonal de reemplazo. Como ésta se plantea por tiempo prolongado, debe ser efectiva en prevenir las complicaciones y en suprimir el síndrome climatérico. Se estudió la eficacia de la asociación de valerato de estradiol (VE) y acetato de ciproterona (CPA) en la reducción de los síntomas asociados a menopausia. Se analizaron, prospectivamente, 342 mujeres durante 6 meses, consignando la intensidad de sus síntomas y los cambios en peso, presión arterial y parámetros bioquímicos. Las oleadas de calor, así como otros síntomas y signos, disminuyeron en intensidad. No hubo diferencia significativa en la evolución del peso ni de la presión arterial, aunque sí en algunos parámetros del perfil lipídico y hepático. Se concluye que la asociación VE y CPA reduce la intensidad de los síntomas climatéricos en el grupo estudiado

Urinary continence following posterior urethral valves treatment.

This retrospective study discusses the incidence of symptomatic voiding dysfunction, the etiological factors and the changes with age and with increasing duration of follow up in 67 boys treated for posterior urethral valves and followed up for a period ranging from 1-21 years. Twenty three of the 67 patients (34.3%) had symptomatic voiding dysfunction; the commonest symptom being nocturnal enuresis with diurnal urgency and frequency. Data in this study suggests a definite decrease in the incidence of urinary incontinence as the patient grows older or as the duration of follow up after valve fulguration increases. A Tc-99m DRCG based uroflowmetry was available in 31 of the 67 patients at the time of this review and evidence of detrusor dysfunction was identified in 9 of the 31 patients on the basis of uroflowmetry. Of significance was the detection of detrusor dysfunction on uroflowmetry in 3 patients with a history of normal urinary control and urinary stream with persistent post treatment hydroureteronephrosis eventually culminating into renal failure. Imipramine therapy was given to 10 of the 17 patients with symptoms of urinary frequency, urgency and nocturnal enuresis with a significantly symptomatic improvement in 9 of these patients. Urinary incontinence, detrusor dysfunction and its effect on the upper tracts and renal function is a significant determinant of the long term outcome of the boys treated for posterior urethral valves and this paper emphasises on the need to carefully evaluate and treat this aspect of all valve patients.
