ABSTRACT

BACKGROUND: Benign prostatic hyperplasia (BPH) is a prevalent disease associated with lower urinary tract symptoms (LUTS). The standard of care for moderate-to-severe LUTS unresponsive to pharmacological treatment is the transurethral resection of the prostate (TURP). However, this intervention is not exempt from complications. Prostatic artery embolization (PAE) has been described as a new, effective and safe procedure for the treatment of LUTS secondary to BPH. To date, only one clinical trial has been published on the use of PAE for LUTS, but the study was methodologically flawed in terms of safety monitoring. Therefore, well-designed clinical studies are required to compare the efficacy and safety of both techniques in the treatment of LUTS secondary to BPH. METHODS AND DESIGN: This was a prospective, randomized, non-inferiority clinical trial comparing efficacy and safety of PAE and TURP in the treatment of BPH-related LUTS. A total of 60 patients diagnosed with BPH with obstructive moderate or severe LUTS refractory to medical therapy and candidates for TURP were randomized to either PAE or TURP. The presence and severity of LUTS were assessed using the validated Spanish version of the International Prostate Symptom Score (IPSS). Primary end points included improvement in maximum urinary flow rate (Qmax) as measured at baseline and 1 year after the intervention. Improvement in IPSS as measured at baseline and after the intervention, reduction in prostate volume, no deterioration or improvement of sexual function (International Index of Erectile Function [IIEF]), reduction in PSA and PVR, satisfaction of the patient with the operation and adverse events occurring during the study were secondary outcome measures. DISCUSSION: The aim of this clinical study was to investigate whether PAE is a valid therapeutic option for LUTS that is not inferior to TURP in terms of efficacy and safety. This study also helped to define the profile of candidates for PAE and analyzed the benefits and complications associated with this new technique.

ABSTRACT

OBJECTIVE: To report one case of bilharziasis treated at our centre and to briefly comment the literature in the current context of increase of parasitical diseases in Europe, imported from the Third World by immigrants and tourists. METHODS: We report the case of a male patient from a Central African country referred to our department due to penile pain with painful voiding and ejaculation for several months, without other clinical symptoms. We performed a bibliographic search in the PubMed and Up-to-date databases with the following search terms: schistosomiasis, bilharziasis, hematuria, bladder infection, parasitosis, combined by boolean operators. RESULTS: After cystoscopy and pathologic study of the biological material the final diagnosis was chronic bilharziasis. The patient remains asymptomatic 14 months after treatment with praziquantel. CONCLUSIONS: Bilharziasis or schistosomiasis is a rare parasite disease, potentially severe which can severely compromise the urinary tract. In developed countries the cases are mainly imported from sub-saharian countries and other areas of North Africa, South Africa, Asia and Middle East. The cause is a parasite, Schistosoma haematobium, from the family of trematodes, genus helmints. In the active phasee the diagnosis is facilitated by the presence of Schistosomal eggs in urine. In latent or non active phase it is necessary the performance of cystoscopy and analysis of the biological material to reach the diagnosis.

ABSTRACT

OBJETIVO: Presentar un caso clínico atendido en nuestro centro y comentar brevemente la literatura en el contexto actual del incremento de las enfermedades parasitarias en Europa, importadas del tercer mundo con la inmigración y el turismo. MÉTODO: Estudio de un paciente varón procedente de un país centroafricano que fue remitido a nuestro servicio debido a dolor en pene acompañado de micciones y eyaculaciones dolorosas de varios meses de evolución sin otra clínica acompañante. Como estrategia de búsqueda bibliográfica se utilizó la bases Pubmed y Uptodate con los siguientes descriptores: Schistosomiasis, Bilharziasis, Haematuria, Vesical Infection, Parasitosis, combinados con operadores boleanos. RESULTADO: Tras cistoscopia y estudio anatomopatológico del material biológico se llegó al diagnóstico de Bilharziasis en estadio crónico. El paciente permanece asintomático 14 meses tras tratamiento con Praziquantel. CONCLUSIONES: La bilharziasis o esquistosomiasis es una enfermedad parasitaria poco frecuente pero potencialmente grave que puede comprometer seriamente el aparato urinario. En los países desarrollados los casos son importados principalmente del África subsahariana y también de otras zonas como África del Norte, Sudáfrica, zonas de Asia y de Oriente Medio. Su causante es el parásito Schistosoma haematobium del género platelminto, familia de los tremátodos. En fase activa el diagnóstico es facilitado por la presencia de los huevos del schistosoma en la orina. En fase latente o inactiva es necesario la realización de uretrocistoscopia y el análisis de materiales biológicos para llegar al diagnóstico

ABSTRACT

OBJECTIVES: To evaluate the usefulness of percutaneous or laparoscopic application of radiofrequency for ablation of tumoral tissue in patients with the diagnosis of solitary renal tumor. METHODS: 3 male patients (one with bilateral renal tumor) underwent 4 radiofrequency ablation treatments (1 laparoscopic, 3 percutaneous) for renal masses between 1.5 and 5 cm (average 3.15 cm). Percutaneous approach was gained under ultrasound control. Energy was applied progressively, following standardized tables, requiring between 2 (tumor diameter 1.5 cm) and 4 cycles (diameter 5 cm) applied in quadrants. Postoperative control was performed in all cases by IV contrast helical CT scan. RESULTS: Treatment was completed in all cases. In one case, laparoscopic tumorectomy was also performed. Radiofrequency cycles oscillated between 30 and 19 minutes depending on tumor size. There were not procedure-derived complications. IV contrast CT scan controls at 3 and 6 months showed absence of tumor in one case (1.5 cm) and absence of intratumoral contrast uptake in the rest of them. CONCLUSIONS: Radiofrequency ablation of small renal tumors, either percutaneous or laparoscopic, is a well-tolerated and minimally invasive procedure. Adequate parameters to consider complete tumor tissue destruction remain to be determined and validated.

ABSTRACT

OBJECTIVES: To analyze the effect of injury of the sympathetic element of vesico-urethral innervation on lower urinary tract. METHODS: We studied clinical, urodynamic, and radiological features in a sample of 261 patients studied because of neurogenic vesico-urethral dysfunction. Three types of inferior sympathetic lesions were established based on urodynamic and radiologic behaviors. We studied relationships between this kind of lesions and clinical, urodynamic, and radiological features, as well as the association of lower sympathetic lesions with the rest of vesicourethral innervation elements. Results were analyzed by logistic regression, and linear multivariate regression, controlling for urodynamic factors, age, sex, and different neurological diagnosis. RESULTS: 95 patients were diagnosed of lower sympathetic lesions. This type of lesions were observed in relation to congenital pathology, being more frequent in boys. These lesions were related with urinary incontinence and vesicoureteral reflux. Lesions producing bladder dynamics disturbances had a higher location than those responsible for bladder neck incompetence development. CONCLUSIONS: Vesicourethral sympathetic innervation lesion of the lower motor neuron type is related to urinary incontinence and vesicoureteral reflux, being bladder neck complex incompetence a determinant factor in both circumstances. This kind of lesions could be a group of different types, with location in different parts of the central and peripheral nervous system that produce very different vesicourethral behaviors.

ABSTRACT

OBJETIVOS: Analizar el efecto de la lesión del elemento simpático de la inervación vesicouretral, en el tracto urinario inferior. MÉTODOS: Se estudiaron las características clínicas, urodinámicas y radiológicas en una muestra de 261 pacientes estudiados por disfunción vesicouretral neurógena. De acuerdo con el comportamiento urodinámico y radiológico, se establecieron 3 tipos de lesión inferior simpática (I,II y III). Se estudió la relación de este tipo de lesiones con factores clínicos, urodinámicos y radiológicos, así como la asociación de la lesión simpática inferior, con el resto de elementos de la inervación vesicouretral. Los resultados se analizaron mediante regresión logística y lineal multivariante, controlando los factores urodinámicos, la edad, el sexo y los diferentes diagnósticos neurourológicos. RESULTADOS: Se diagnóstico de lesión inferior del simpático a 95 pacientes. Este tipo de lesiones se observaron en relación con patología congénita, siendo más frecuente en los niños. Este tipo de lesiones, se relacionaron con la incontinencia urinaria y el reflujo vesicoureteral.Las lesiones que produjeron alteraciones dinámicas vesicales, fueron de localización más alta que las responsables de la producción de incompetencia del cuello vesical. CONCLUSIONES: La lesión simpática tipo neurona motora inferior, de la inervación vesicouretral, se relaciona con la incontinencia urinaria y el reflujo vesicoureteral, siendo un factor determinante de ambas circunstancias, la incompetencia del complejo del cuello vesical. Este tipo de lesiones podría ser un conjunto de tipos diferentes, que se localizan en diferentes zonas del sistema nervioso central y periférico y que originan comportamientos vesicouretrales muy diferentes (AU)

ABSTRACT

OBJETIVOS: La inclusión de la vejiga -generalmente un divertículo de ésta- constituye un hallazgo infrecuente a pesar de la elevada prevalencia de la patología herniaria en el adulto. Analizamos un caso clínico, con esta inusual concomitancia. MÉTODO: Se describe el caso clínico expuesto anteriormente: - Divertículo vesical gigante asociado a hernia inguinal. RESULTADOS: En este caso clínico, dado el gigantismo del divertículo y la asociación con patología obstructiva urinaria baja por hipertrofia prostática fue necesaria la resolución de ambos procesos: - Diverticulectomía, con corrección de la hernia inguinal y resección transuretral de la hipertrofia prostática. CONCLUSIONES: Los divertículos vesicales se asocian a obstrucción urinaria baja, generalmente por patología de la glándula prostática. La inclusión de los divertículos vesicales en un proceso herniario, es inusual. La sintomatología suele ser escasa, siendo indistinguible de la propia sintomatología miccional prostática. El diagnóstico a parte de la clínica, se basa en la ecografía, cistografía o la urografía intravenosa. La opción terapéutica suele ser la cirugía y generalmente intentando resolver toda la patología -el divertículo vesical y la obstrucción miccional provocada por la hipertrofia prostática (AU)
