Impacto de la prostatectomía radical en los resultados urodinámicos de pacientes con cáncer de próstata tratados con radioterapia de intensidad modulada / Impact of a radical prostatectomy on the urodynamic results of prostate cancer patients treated with intensity modulated radiation therapy

Introducción y objetivos Evaluar el efecto de la prostatectomía radical y la edad en los resultados urodinámicos antes y después de la radioterapia de intensidad modulada administrada a pacientes con cáncer de próstata. Materiales y métodos La muestra incluyó a 40 pacientes con cáncer de próstata, 22 de los cuales habían sido sometidos a prostatectomía radical. Se midieron y compararon los parámetros urodinámicos antes y después de una media de 4,2 meses de radioterapia. La radioterapia externa se administró mediante técnicas de terapia de arco volumétrico modulado y de radioterapia de intensidad modulada. Resultados No se vieron cambios significativos en los parámetros de uroflujometría. En el caso de la cistomanometría los datos no mostraron un aumento de la incontinencia urinaria de esfuerzo secundaria, pero sí un incremento del 7% en la incontinencia urinaria de urgencia. Hubo cambios estadísticamente significativos en la reducción de la capacidad vesical, con un deseo miccional fuerte, con urgencia miccional y también en la presión del detrusor con un deseo miccional normal. Además, el estudio de presión/flujo reveló una reducción estadísticamente significativa del volumen de orina residual. Conclusiones El efecto de la prostatectomía y la edad varía según la evolución del estudio urodinámico. Hubo una reducción significativa del volumen de orina residual, así como de la presión del detrusor, con un deseo miccional normal en los pacientes sin prostatectomía y en aquellos menores de 75 años. Además de un aumento en la incontinencia de urgencia, también se produjo un empeoramiento significativo del resultado urodinámico de llenado vesical y una disminución de la capacidad vesical cistomanométrica, con un deseo miccional fuerte y urgencia miccional. Ninguno de estos factores se vio afectado por la edad o la prostatectomía (AU)

Introduction and objectives To evaluate the effect of radical prostatectomy and age on urodynamics before and after intensity-modulated radiation therapy administered to prostate cancer patients. Materials and methods The sample consisted of 40 prostate cancer patients, 22 of whom had undergone a radical prostatectomy. Urodynamic parameters before and after an average of 4.2 months of radiotherapy were measured and compared. External radiotherapy was administered via Volumetric Modulated Arc Therapy (VMAT), Intensity Modulated Radiation Therapy (IMRT) techniques. Results Uroflowmetry presented no significant parameters. In the case of Cystomanometry, the data did not show an increase in secondary stress urinary incontinence, although there is 7 percent increase in urge urinary incontinence. There were statistically significant changes in reduced bladder capacity with a strong desire to void, with an urge to void and also in the detrusor pressure with a normal desire to void. Furthermore, pressure/flow analysis revealed a statistically significant reduction of residual urine volume. Conclusions The effect of prostatectomy and age varies according to the evolution of urodynamics. There was a significant reduction in terms of residual urine volume and detrusor pressure with a normal desire to void in patients without a prostatectomy and in those under 75 years old. In addition to an increase in urge incontinence, there was also a significant worsening of the bladder filling urodynamics and a decrease in the cystomanometric bladder capacity with a strong desire and an urge to void. None of these were modified by age or prostatectomy (AU)

Urodynamic findings in Charcot-Marie-Tooth patients with lower urinary tract symptoms. / Hallazgos urodinámicos en pacientes con enfermedad de Charcot-Marie-Tooth con síntomas del tracto urinario inferior.

INTRODUCTION: Our aim was to describe the lower urinary tract symptoms (LUTS) and urodynamic findings in Charcot-Marie-Tooth (CMT) disease patients referred to our Urology Department. METHODS: Retrospective study of those patients with CMT disease diagnosed at the Neurology Department of our Tertiary Hospital and referred to our Urology Department since 2008 due to LUTS. We reviewed their clinical charts regarding the age at CMT disease diagnosis, type of CMT disease and the presence of other comorbidities which could cause LUTS. We collected data on the characterization of LUTS, findings of neurological examination and urodynamic findings. RESULTS: Seven patients were referred to our department due to the presence of LUTS. They were 3 male and 4 female, with median age at the moment of LUTS onset of 55 (29-67) years and median time from the diagnosis of the neuropathy to the onset of LUTS was 14 (1-37) years. Voiding symptoms were referred by 5 patients and urinary incontinence by 3 patients. Two patients presented recurrent urinary tract infection. Six urodynamic tests were performed which showed a neurogenic acontractile detrusor in 2 patients, detrusor underactivity in one patient, a delayed opening time in one patient, a neurogenic detrusor overactivity in one patient and a urodynamic stress incontinence in one patient. In one patient the urodynamic test was normal. CONCLUSIONS: Most of CMT patients with LUTS complained from voiding symptoms. Several urodynamic findings could be observed mostly during the voiding phase. We recommend performing urodynamic tests in CMT patients presenting with LUTS seeking for treatment or in those with related complications.

Clinical and urodynamic impact of detrusor overactivity in women with overactive bladder. / Repercusión clínica y urodinámica de la presencia de hiperactividad del detrusor en mujeres con vejiga hiperactiva.

OBJECTIVE: To evaluate the clinical and urodynamic differences (associated with the presence or absence of detrusor overactivity [DO]) in women with overactive bladder (OAB) referred to Functional Urology and Urodynamic Units in Spain. MATERIAL AND METHODS: Observational, cross-sectional, multicenter and prospective study conducted in Spain in women with clinical diagnosis of OAB, who had been referred to urodynamic study (UDS) of which centralized reading was performed. Patients completed the 3-day voiding diary (DM3d) with the PPIUS scale (Patient Perception of Intensity of Urgency Scale), the B-SAQ (Bladder Self-Assessment Questionnaire) and the OABq-SF (Overactive Bladder Questionnaire Short Form). The questionnaires and UDS variables of women with OAV, with or without DO, were compared using the Mann-Whitney test (continuous variables) and the chi-square test (χ2) (categorical variables). RESULTS: A total of 247 women with OAB were evaluated, and 103 of them had DO. According to the presence or absence of DO, significant differences were observed in the number of episodes of urge urinary incontinence (UUI), urinary frequency, nocturia, mean micturition volume and number of pads (P<.05 for all comparisons). A higher percentage of patients with OAB and DO presented reduced bladder capacity, urgency, urge urinary incontinence (UUI) and lower volume for first voiding desire, strong desire to void and maximum cystomanometric capacity in UDS compared with patients without DO (P<.05 for all comparisons). The only significant differences between both groups were regarding the B-SAQ symptoms scale (P=.011). CONCLUSIONS: The presence of DO in women with OAB is related to a more severe alteration of the bladder filling phase.

[Female urinary incontinence: An update]. / Actualización en incontinencia urinaria femenina.

The urinary incontinence is a highly prevalent symptom in the adult female population. It has important psychosocial and economic connotations, and affects the quality of life of these patients. As it is an under-diagnosed problem due to patients not always consulting for it, it is very important to keep this in mind and to provide an opportunistic screening from Primary Health Care. It is difficult to determine the costs of this, but it is estimated to be the 2% of the health budget. Because of all of this, it is very important to know how to make a correct diagnose of this condition, to determine the different types of incontinence, possible causes, and treatments available. The purpose of this review is to show the different diagnostic and therapeutic tools available, to show the Primary Health Care role in this condition, and when to refer to specialist care.

Urodynamic assessment of bladder and urethral sphincter function before and after robot-assisted radical prostatectomy.

INTRODUCTION: Affectation of the bladder after open prostatectomy is demonstrated. Decrease in bladder capacity and bladder compliance, detrusor hyper-or hypo-activity and voiding dysfunction are observed. We propose to investigate the effects of robotic surgery on bladder and sphincter function through the comparative study of preoperative and postoperative urodynamic values 3 months after prostatectomy. MATERIAL AND METHODS: Prospective study of 32 consecutive patients undergoing robotic prostatectomy. They all underwent urodynamic study one month before the intervention and 3 months after the radical prostatectomy. RESULTS: Twenty five percent of patients undergoing robotic prostatectomy showed detrusor hyperactivity accompanied by a decrease in bladder compliance of 30.2 to 21.8 ml/cmH2O. Urethral profile showed diminished functional length of 67 to 44 mm and decreased maximum urethral pressure of 48.5 to 29.3 cmH2O. After robotic prostatectomy 21.8% of patients had detrusor hypoactivity, obstruction decreased between 28.1% to 12.5%. CONCLUSIONS: Decreased bladder compliance, detrusor hypo- or hyperactivity and obstruction improvement observed in the study of the flow pressure have been associated with sphincter involvement. It is part of the complex of lower urinary tract dysfunction that occurs after robotic prostatectomy.

Evaluación urodinámica de la incontinencia urinaria después de prostatectomía radical: [revisión] / Urodinamic evaluation after radical prostatectomy

El estudio de la incontinencia urinaria después de prostatectomía radical (IUPR) debe basarse en el reporte del propio paciente en una evaluación realizada por una tercera persona y debe incluir el tiempo transcurrido después de la cirugía. Los estudios poblacionales suelen reportar frecuencias mayores que aquellas de centros de referencia. El estudio urodinámico de la IUPR incluye la evaluación de: A) la disfunción esfinteriana a través de las mediciones de la presión de punto de escape con Valsalva y del perfil de presión uretral; B) la disfunción vesical a través de la cistometría de llene, cuyo objetivo es demostrar la existencia de detrusor hiperactivo o acomodación vesical disminuida; y C) la incontinencia de orina por rebosamiento (ya sea por obstrucción o alteración de la contracción del detrusor) a través del análisis del estudio flujo – presión de la micción. Se analizan estudios de pacientes con IUPR con urodinamia realizada al menos 6 meses después de la cirugía, cuyas diferentes metodologías deben considerarse en la interpretación de los resultados. La incontinencia urinaria de esfuerzo está presente en entre 60 por ciento y 100 por ciento de los pacientes analizados (8 por ciento a 71 por ciento como hallazgo exclusivo). La frecuencia de detrusor hiperactivo varía entre 19 por ciento y 92 por ciento de los casos (0,7 por ciento a 40 por ciento como alteración única); pocos estudios informan su presencia como causa efectiva de incontinencia urinaria, lo que ocurre en entre 7,2 por ciento y 27 por ciento de los casos. La acomodación disminuida se describe enun amplio rango de entre 1,7 por ciento y 56 por ciento de los pacientes. Pocos estudios informan disminución de la contractilidad del detrusor la cual varía en entre 29 por ciento y 33 por ciento de los casos, y obstrucción a la salida dela vejiga la que puede existir en hasta 21 por ciento de los pacientes.

The assessment of urinary incontinence after radical prostatectomy (UIRP) must be based on the patient’s own report on an evaluation by a third person and also include the time elapsed after surgery. The population studies often report higher frequencies than those of reference centers. The UIRP urodynamic study includes evaluation of A) the sphincter dysfunction through measurement of the Valsalva leak point pressure and urethral pressure profile, B) the bladder dysfunction by filling cystometry, which aims to demonstrate the existence of detrusor overactivity or impaired compliance and C) the overflow incontinence (either by obstruction or impaired detrusor contraction) through analysis of the pressure – flow study of urination. We analyze a selection of studies of patients with UIRP in which the urodynamic study was conducted at least 6 months after surgery, which use different methodologies that should be considered in the interpretation of the results. Stress urinary incontinence is present in between 60 percent and 100 percent of tested patients (8 percent to 71 percent as an exclusive finding). The frequency of detrusor overactivity varies between 19 percent and 92 percent of the cases (0.7 percent to 40 percent as a single alteration); few studies report its presence as an effective cause of urinary incontinence, which occurs in between 7,2 percent and 27 percent of the cases. The decreased compliance is described in a wide range of between 1,7 percent and 56 percent of the patients. Few studies report decreased detrusor contractility which varies between 29 percent and 33 percent of the cases, and bladder outlet obstruction which can exist in up to21 percent of the patients.
