[Kaposis sarcoma in a renal graft]. / Sarcoma de Kaposi sobre injerto renal.

Kaposi's sarcoma is an infrequent tumor of unknown cause, but with a higher impact in immune depressed individuals, particularly in HIV and transplant patients. It usually appears as a benign cutaneous lesions, while the invasive visceral form is uncommon with malignant evolution and wit rare remission. We present a patient with a Kaposi's sarcoma localised in a renal graft and bad response even when immuno suppression was discontinued.

Quiste de Tarlov y disfunción vesical sintomática / Tarlov cyst and symptomatic bladder disfunction

El quiste de Tarlov o quiste perineural son lesiones de las raíces nerviosas localizadas a nivel de la región sacra y de etiología incierta. La mayoría de estos quistes permanecen asintomáticos y carecen de relevancia clínica. Los quistes sintomáticos son infrecuentes y los síntomas más habituales son el dolor y las radiculopatías. Nosotros presentamos el caso de una mujer de 53 años con un quiste de Tarlov sintomático ( síndrome de frecuencia y urgencia miccional) que tras el tratamiento quirúrgico presenta una mejoría clínica importante (AU)

Tarlov cysts or perineural cyst are lesions of the nerve roots located at the sacral level and uncertain etiology. Most of these cysts remain asymptomatic with no clinical relevance. The symptomatic cysts are uncommon and the usual symptoms are pain or radiculopathy. We report the case of a 53 year old woman with a symptomatic cyst (with a history of frequency and urgency syndrom), that disappears after surgery (AU)

Sarcoma de Kaposi sobre injerto renal / Kaposi´s sarcoma in a renal graft

El sarcoma de Kaposi es un tumor infrecuente de causa desconocida, pero con una mayor incidencia en pacientes inmunodeprimidos, sobre todo en trasplantados y VIH positivos. Habitualmente se presenta como lesiones cutáneas de buen pronóstico, siendo la forma invasiva visceral rara, agresiva y rara su remisión. Presentamos un paciente con un sarcoma de Kaposi a nivel del injerto renal y mala respuesta a pesar de retirarla inmunosupresión (AU)

Tratamiento quirúrgico de la incontinencia urinaria de esfuerzo mediante cabestrillo suburetral SPARC. Análisis de nuestra experiencia / Stress urinary incontinence surgical treatment with suburethral suprapubic sparc sling

Introducción: La incontinencia urinaria de esfuerzo (IUE) presenta una gran morbilidad y una elevada incidencia. Existen múltiples técnicas quirúrgicas descritas para el tratamiento de la misma, con diversos resultados. Los cabestrillos suburetrales se han establecido en los últimos años como un método simple y poco invasivo para el tratamiento de la incontinencia urinaria de esfuerzo. Material y Método: Analizamos retrospectivamente nuestra serie de 86 pacientes diagnosticadas de IUE, intervenidas, entre Octubre de 2001 y Diciembre de 2005, mediante un cabestrillo suburetral suprapúbico (SPARC(C)). Resultados: La media de edad es de 58,7 años (39-80). La estancia media hospitalaria es de 2,43 días (1-8) y la duración media de sonda de 1,52 días (1-10). En el 14,5% de los casos, se realizó cirugía asociada, siendo la más frecuente, la colpoperineoplastia anterior (10,7 %). Las complicaciones son poco frecuentes; perforación vesical (5,8%), RAO antes del alta (7%), ITU (15,3%), RAO crónica (3,5%). En el 3,5% de las mujeres, se realizó lisis del cabestrillo, por retención crónica. El seguimiento medio es de 10,14 meses, encontrándose un 71,4% de continencia total. Un 26,2% de las pacientes presentaron síntomas de hiperactividad de novo, con problemas de incontinencia en el 54,5% de estas. (p<0,002; OR 5.0 (IC 95% 1,75-14,28). Conclusiones: El SPARC© es un método sencillo, con un tiempo hospitalario corto y una rápida reincorporación a la vida social. Los resultados pueden ser valorados rápidamente y con una tasa elevada de éxito. La aparición de urgencia de novo es elevada y empeora los resultados funcionales. Es necesario un mayor seguimiento para valorar resultados funcionales a largo plazo

Introduction: Stress urinary incontinence (SUI) has a high incidence and important morbidity. Multiple surgical techniques have been described to treat it, with despair results. Suburethral slings have become, in recent years, a simpler and less invasive method to treat SUI surgically. Material and method: The purpose of this paper is to review, retrospectively, 86 patients treated at our institution, from 10/01 to 12/05 of SUI, with a suprapubic suburethral sling (SPARC). Results: Medium (range) age is 58.7 (39-80), hospital stay was 2.43 d (1-8) and catheter was removed 1.52 d (1-10). 14.5% of patients underwent other vaginal surgeries at same time, most frequently anterior colpoperineoplasty (10.7%). Complications are not very frequent; bladder perforation (5.8%), acute urinary retention (7%), chronic urinary retention (3.5%) and UTI (15.3%). Sling release was performed in 3.5% of women with chronic urinary retention. Total continence was found in 71.4% of patients with 10.1 months medium follow up (1-32). De novo urge symptoms were found in 26.2% of women, with urge incontinence in 54.5% of them. (p < 0,002; OR 5.0 (IC 95% 1.75-14.28). Conclusions: Suprapubic suburethral SPARC sling is a simple method, with few complications and fast social recovery. Outcome can be measured soon, with a high continence rate. De novo urge symptoms are high and they worsen functional results. It is necessary longer follow-up to evaluate long term outcomes

[Vesicoureteral reflux in spinal cord injured patients. Treatment results and statistical analysis]. / Reflujo vesicoureteral en pacientes lesionados medulares. Analisis estadistico de resultados en el tratamiento.

INTRODUCTION: VUR in spinal cord injured patients is cause of important morbidity and mortality. The aim of this paper is to make a statistical, retrospective and descriptive study to analyze VUR treatment results, in neurogenic bladder SCI patients. MATERIAL AND METHOD: We study 40 patients (80 renal units) with VUR in neurogenic bladders and SCI, between March, 1990 and November, 2004. Median age is 43.05 y (9-76). 77.5% of patients are males (3.4:1). Time from injury to VUR is 24.7m (0.2-87). Median follow up is 8.23a (0.5-29). Traumatic lesions are most frequent (70%). Median bladder capacity is 244.9 ml (43-555) and median bladder compliance is 16.12 ml/cm H2O (0.3-61.6). Detrusor overactivity is found in 72.2% and detrusor-sphincter dyssynergia in 71.8%. Initial conservative treatment is done with indwelling catheter and anticholinergics RESULTS: Complete remission was found in 57.5% of RU, descending VUR a 23.7% (66.2% previously to 42.5% after; p<0.02), and predominant in unilateral reflux. Partial response was found in 3.8%, progression in 12.5% and recidiva post CR in 10.9%. Younger patients have better remission rates (39.4 to 47.6 y; p=0.04). Urodinamycs variables don't found any significant differences in treatment results. Endoscopic treatment with bulking agents gets a good response rate (56.3%) (p=0.18). CONCLUSIONS: Initial conservative treatment gets a 23.7% reduction of VUR, especially in men, young and unilateral reflux patients. Anyhow, we observe some progression and recidiva. Detrusor overactivity and detrusor-sphincter dyssynergia didn't influence in treatment results, but they are found in all patients with recidiva. With longer reflux evolution, we observe better responses, but also a higher recidiva rate (p=0.007). Endoscopic bulky injection techniques found out a good response rate (56.3%), also in patients with recidiva after conservative treatment.

Introducción: El RVU en pacientes con lesión medular es una causa importante de morbilidad y mortalidad. El objetivo de este trabajo, es realizar un estudio retrospectivo, descriptivo y estadístico que analiza los resultados en el tratamiento del reflujo vesicoureteral, en los pacientes con vejiga neurógena establecida. Material y método: Se estudian 40 pacientes con RVU, secundario a vejiga neurógena por lesión medular, entre marzo/90 y noviembre/04. Se observa RVU en el 66,2% de las UR. La edad media es 43,05a (9-76). El 77,5% son hombres (3,4:1). La evolución desde la lesión medular hasta el diagnóstico del RVU de 24,7 meses (0,2-87m). El tiempo de seguimiento es de 8,23a (0,5- 29). Etiología traumática en el 70%. La capacidad vesical media es de 244,9 ml (43-555ml), la compliance vesical media es de 16,12 ml/cm. H20 (0,3-61,6). La hiperactividad del detrusor se aprecia en 72,2% y la disinergia vesico-esfinteriana externa en 71,8%. El tratamiento inicial es conservador con sondaje vesical y terapia anticolinérgica. Resultados: Curación completa del RVU en el 57,5%, se reduce un 23,7% (66,2% frente 42,5%, p<0,02); predominantes en reflujos unilaterales. Mejoría parcial, con reducción del grado previo en 3,8%. Progresión a grados superiores en 12,5%. Recidivas post-curación completa en 10,9% Los pacientes más jóvenes curan mejor (39,4 frente a 47,6 años, p=0,04). Al analizar las variables urodinámicas, no encontramos diferencias estadísticas. El tratamiento endoscópico consigue una curación del 56.3% (p=0,18). Conclusiones: Con el manejo conservador inicial, se consigue una reducción del reflujo vesicoureteral en el 23,7%, preferentemente en aquellos pacientes con reflujo unilateral, jóvenes (p=0,04) y varones. La presencia o ausencia de hiperactividad o disinergia, no empeora o mejora los resultados, sin embargo se asocia con recidivas. A mayor tiempo de evolución, mejores tasas de curación, pero también mayores recidivas (p=0,007). El tratamiento endoscópico con sustancias abultantes, obtiene una buena tasa de curación (56,3%), incluso en pacientes recidivados después del tratamiento conservador

[Renal angiomyolipomatosis and pulmonary lymphangiomyomatosis. Its relationship with Bourneville syndrome]. / Angiolipomatosis renal y linfangioleiomiomatosis, su relación con la enfermedad de Bourneville.

INTRODUCTION: Renal angiomyolipomas are not very frequent in urologic activities. Pulmonary lymphangioleiomyomatosis is a rare disease that occurs mainly in women of reproductive age. Tuberous sclerosis shows lesions to different organs, including these both entities. MATERIAL AND METHOD: We retrospectively analyze patients treated in our center. Three most representatives cases are reported. An indexed literature review is done, in order to establish a clinical protocol to manage these kinds of patients. RESULTS: [corrected] Between 1990 and 2004, eight patients have been attended with an angiomyolipoma renal diagnostic. Five women (62%) and three men (38%). Medium age is 52,3y (29-69). In 3 of them (all women), it was also done a diagnostic of pulmonary lymphangioleiomyomatosis. CONCLUSIONS: Bourneville syndrome is not very frequent. Associated angiomyolipomas usually are multiple, bilateral, with tender to grow and require more interventions. Previous diagnostic let us prevent future complications with vigilance, selective arterial embolization and nephron-spare surgery. Tumour size and the presence of symptoms are more decisive to decide best therapy alternative. Young patients with pulmonary lymphangioleiomyomatosis should be advise against pregnancy and the use of preparations containing estrogens.

Angiolipomatosis renal y linfangioleiomiomatosis, su relación con la enfermedad de Bourneville / Renal angiomyolipomatosis and pulmonary lymphangiomyomatosis. It´s relationship with bourneville syndrome

Introducción: Los angiomiolipomas renales son poco frecuentes en la actividad urológica. La linfangioleiomiomatosis es una rara enfermedad pulmonar que afecta mayoritariamente a mujeres en edad reproductiva. La Esclerosis Tuberosa afecta a diversos órganos, incluyéndose entre sus presentaciones, estas dos entidades. Material y método: Se revisan de forma retrospectiva los pacientes atendidos en nuestro centro, haciendo referencia a tres casos representativos de la enfermedad. Se expone su manejo clínico y Resultados: Asimismo se realiza una revisión de la literatura indexada, que nos permita establecer un protocolo de actuación. Resultados: Entre 1990 y 2004, han sido atendidos 8 pacientes con angiomiolipoma renal. 5 mujeres (62%) y 3 hombres (38%). La media de edad es de 52,3 años (29-69). En 3 pacientes (todas mujeres) se diagnosticó también linfangioleiomiomatosis. Conclusiones: La enfermedad de Bourneville es poco frecuente. Los angiomiolipomas que se asocian, suelen ser múltiples, bilaterales, tendentes al crecimiento y requieren más intervenciones. El diagnóstico precoz permite prevenir futuras complicaciones mediante vigilancia, embolización arterial selectiva o cirugía conservadora. Es importante el tamaño y la presencia de síntomas para decidir la mejor terapia. Las pacientes jóvenes con linfangioleiomiomatosis pulmonar deben ser advertidas del uso de preparados estrogénicos y evitar embarazos

[Traumatic urethral disruption in women. A rare entity. Report of two cases]. / Rotura traumática de uretra femenina: una rara entidad. Aportación de dos casos.

We present two cases of urethral disruption in women, a very uncommon situation because of the anatomical features. Yet it must be always suspected in all women under a pelvic politraumatism, for eviting important problems. Both cases are traffic politraumatized young girls presenting with pelvic fracture, among others. The surgery performed was combined suprapubic-transvaginal approach, even in one a previous endoscopic realinement was done, who also needed endoscopic complementary treatment: electrofulguration of a fistulous bridge. Outcome of both is fine, achieving good continence. We also make a literature review.

Rotura traumática de uretra femenina: una rara entidad. Aportación de dos casos / Traumatic urethral disruption in women. A rare entity. Aportation of two cases

Presentamos dos casos clínicos de rotura de uretra femenina, una situación poco frecuente por las características anatómicas de la mujer pero que debe ser sospechada precozmente, ante todo politraumatismo pélvico, para evitar graves problemas. Los casos expuestos son dos pacientes jóvenes politraumatizadas por accidentes de tráfico con fracturas óseas pélvicas. En ambas se realizó cirugía combinada suprapúbica-vaginal, una de ellas previo realineamiento endoscópico precoz. Esta precisó tratamiento endoscópico complementario: electrofulguración de pequeño orificio fistuloso. La evolución de ambas es buena con continencia. Hacemos una revisión de la literatura (AU)

[Double-barreled wet colostomy: analysis of a urinary diversion]. / Colostomía húmeda en doble barra: análisis de una derivación.

We analyse our experience in performing the wet colostomy, also called urocolostomy and present seven cases treated at our hospital in which this was used. We present: a) three women, one underwent an urocolostomy as a result of a myelomeningocele with urinary and fecal incontinence, another because of a pelvic malignancy, and the third after developing a post radiotherapy cysto-proctitis; b) four men, one underwent this surgical procedure as a result of a traumatic paraplegia with multiple urinary fistulae and neurogenic bladder, the other three were secondary to pelvic malignancies (two bladder and one sigmoid malignacies). The outcome was fine in all cases with no pyelonephritis or metabolic imbalances; in all cases it represented a good option for these patients.

Colostomía húmeda en doble barra: análisis de una derivación / Double barred wet colostomy: analysis

En este artículo revisamos y analizamos nuestra experiencia en la realización de la colostomía húmeda o urocolostomía presentando siete casos. Se trata de: tres mujeres a una de las cuales se le practicó una urocolostomía por un mielomeningocele con incontinencia total de heces y vejiga neurógena, a otra por una neoplasia ginecológica tras exenteración pélvica, y a la tercera debido a una cistoproctitis rádica tras radiación por neoplasia ginecológica. Cuatro hombres de los cuales en uno se realizó urocolostomía por una paraplejia con múltiples fístulas urinarias y vejiga neurógena y tres tras exenteraciones pélvicas por neoplasias (en dos casos vesicales y en otro caso de sigma con infiltración vesical). Los resultados fueron buenos durante el seguimiento de todos los casos no habiéndose reportado casos de alteraciones metabólicas ni pielonefritis. En todos los casos representó una buena opción terapéutica para estos pacientes. (AU)

[Kidney transplants from asystolic donors]. / Trasplante de riñón procedente de donantes en asistolia.

Review of our experience on renal transplantation with graft from removal in asystole. We have performed 31 transplantations of kidneys removed while in asystole, 25 of which were treated only with cardiocompression and assisted ventilation as support measures, the average asystole time being 45 minutes. Two donors were treated by in situ cold perfusion of the abdominal organs (time of asystole, 70 and 218 minutes). One patient was maintained with body cooling by cardiopulmonary by-pass for 90 minutes. Graft survival at three months was 77%, with a delay in the initial function of 70%, secondary to acute tubular necrosis, this being the only parameter in which a significant difference is observed when comparing them to those from a control group of 50 transplant performed over the same interval. No significant differences were seen at one year with regard to either graft survival or the recipients in both groups.

[Ileal cystoplasty in bladder cancer]. / Cistoplastia ileal en el cáncer de vejiga.

We present our experience with bladder substitution in radical surgery for bladder cancer. Ileocapsuloplasty was performed in 40 patients. There were 2 postoperative deaths and 11 patients died from tumor recurrence or progression 2 to 10 years later. Two patients had urothelial tumor recurrence in the capsuloplasty. Day continence was good in 89.5% of the cases and 10.5% were partially continent. Night continence was good in 23.5%, partial in 23.5% and poor in the remaining 53% of the patients. Detubularized ileal cystoplasty was performed in 9 patients. Two patients have died; one early postoperatively and the other from tumor progression. Day continence was good in all of the patients and night continence was good in four of the seven patients that were evaluated.

[Long-term results of conservative treatment of ureteral fistulas]. / Resultados a largo plazo del tratamiento conservador de las fístulas ureterales.

Techniques for conservative management of different upper urinary tract pathologies have been widely used in the last decade. Endourological treatment of ureteral fistulas is one of the fields which has developed significantly. Our experience in the management of this condition consists of 9 patients that had been treated from 1983 to the present time. Four of these were in transplanted kidneys. Fistula repair was achieved in 8 cases, although one developed secondary urethral stricture. One patient required open surgical correction. There were no deaths or loss of any renal unit. A mean follow-up of 44 months revealed no complications. We consider this therapeutic modality to be the procedure of choice in patients with ureteral fistulas.

[Bilateral adrenal gland metastasis of adenocarcinoma of the kidney]. / Metástasis suprarrenal bilateral por adenocarcinoma renal.

We report on a 52-year old male with simultaneous bilateral adrenal metastases from renal adenocarcinoma. The patient was submitted to radical nephrectomy, including the ipsilateral adrenal, and contralateral adrenalectomy, and received coadjuvant steroid replacement therapy. The patient died 11 months post-operatively. Similar cases previously reported in the literature are reviewed.
