[Low-grade collecting duct carcinoma of the kidney in a patient treated by dialysis]. / Carcinoma renal de los conductos colectores de bajo grado en un paciente en tratamiento con hemodiálisis.

Patient treated by dialysis for end-stage renal disease are at increased risk of many cancers, especially those of kidney and urinary tract. A 56 years old man who undergoing chronic dialysis, presented in ultrasonography a 2 cm complex cystic mass in the left kidney what was confirmed by computed tomography and magnetic resonance. A laparoscopic left nephrectomy was performed. Histological examination showed a low grade collecting duct carcinoma of the kidney. An infrequent variant of kidney tumor.

Carcinoma renal de los conductos colectores de bajo grado en un paciente en tratamiento con hemodiálisis / Low-grade collecting duct carcinoma of the kidney in a patient treated by dialysis

Los pacientes en tratamiento con diálisis por enfermedad renal en estadio terminal tienen un riesgo aumentado de padecer varios tipos de cáncer, especialmente de riñón y del tracto urinario. Presentamos el caso de un varón de 56 años en tratamiento con hemodiálisis. En una ecografía de control se apreció una imagen compatible con un quiste complicado de unos dos centímetros a nivel del polo inferior de riñón izquierdo, que es confirmada mediante TC y RM abdominal. Se practicó una nefrectomía izquierda por vía laparoscópica. El diagnóstico histológico fue de carcinoma renal de los conductos colectores de bajo grado, una variante infrecuente de tumor renal (AU)

[The use of double J stent for prevention of urological complications in kidney transplants]. / Empleo del catéter doble J para la prevención de las complicaciones urológicas en el trasplante renal.

OBJECTIVE: To analyze the impact of the use of the double J stent in the incidence of urological complications, like fistula urinary and ureteral obstruction in kidney transplants. MATERIALS AND METHODS: Between August 2003 and December 2005, 59 adult recipients underwent renal transplant. A retrospective study was conducted on two groups of patients: Group A with double J stent and group B without it. We reviewed the urological complications: fistula, ureteral obstruction and urinary tract infection. RESULTS: Group A: One ureteral obstruction and two urinary fistulas (7%) were developed in this group. 13 patients (46%) had a positive urinary culture. In only one case was necessary to retire the double J stent because of ureteral obstruction. Group B: Four patients (13%) developed ureteral obstruction and another five (16%) developed urinary fistula. 9 patients (29%) had a positive urinary culture. CONCLUSION: The routine insertion of a double J stent in kidney transplants reduces the number of early complications urinary fistula and ureteral obstructions.

Empleo del catéter doble J para la prevención de las complicaciones urológicas en el trasplante renal / The use of double J stent for prevention of urological complications in kidney transplants

Objetivo: Analizar si la cateterización sistemática de la anastomosis ureterovesical en el trasplante renal mediante un catéter doble J disminuye la incidencia de las complicaciones urológicas tipo fístula y estenosis ureterales. Material y métodos: En el periodo comprendido entre agosto de 2003 y diciembre de 2004 realizamos 59 trasplantes renales de donante cadáver. Establecemos dos grupos, grupo A pacientes que durante el trasplante se les coloca un catéter doble J y grupo B pacientes trasplantados sin colocación de catéter. Mediante un estudio retrospectivo analizamos la incidencia de fístulas urinarias, estenosis ureterales y procesos infecciosos en ambos grupos. Resultados: En el grupo A (con catéter doble J) se detectaron 1 caso de estenosis ureteral y 2 casos (7%)de fístula urinaria. En un paciente fue necesaria la retirada del catéter al producir obstrucción por coágulos. Trece pacientes (46%) presentaron un cultivo de orina positivo. En el grupo B (sin catéter doble J) se evidenciaron 4 casos (13%) de estenosis ureteral y 5 casos (16%) de fístula urinaria. Nueve pacientes (29%) presentaron un cultivo de orina positivo. Conclusión: El empleo del catéter doble J de forma profiláctica en el trasplante renal, disminuye las fístulas urinarias y en mayor medida las estenosis ureterales (AU)

[Intrascrotal metastasis in a renal cell carcinoma]. / Metástasis intraescrotal de un carcinoma renal.

The present article reports a case of intrascrotal metastasis of renal adenocarcinoma. This is an unusual case. A 66-year-old male patient undewent right radical nephrectomy and cavotomy for renal cell carcinoma with renal vein infiltration and thrombus in cava. Six months later the patient present with a nodulous enlargement intrascrotal and roots of penis. And he died 15 moths after nephrectomy. Usually intrascrotal metastases are a late event in the course after detection of a renal carcinoma.

Metástasis intraescrotal de un carcinoma renal / Intrascrotal metastasis in a renal cell carcinoma

Comunicamos un caso, infrecuente, de metástasis intraescrotal de un carcinoma renal. Se trata de un paciente varón de 66 años, sometido a nefrectomía radical con cavotomía por un carcinoma de células renales con infiltración en la vena renal y trombo en cava. Seis meses después, consultó por la aparición de unos nódulos intraescrotales y en raíz de pene. El paciente falleció 15 meses después de la nefrectomía. Habitualmente las metástasis intraescrotales son un evento tardío después de la detección del carcinoma renal (AU)

[Intra-sinusal renal angiomyolipoma. Differential diagnosis from renal artery aneurysm]. / Angiomiolipoma renal intrasinusal. Diagnóstico diferencial con el aneurisma de arteria renal.

We report a case of atypical renal angiomyolipoma (AML) because of its clinic presentation like colic renal pain, its uncommon intrasinusal location, its low fatty content, and especially because of the diagnostic doubt with a renal artery aneurysm that could not be resolved before the surgery in spite of making Doppler ultrasound, renal one sided arteriography, computed tomography (CT) and magnetic resonance imaging (MRI). We gave up doing a percutaneous needle biopsy because of the location, the association with hematoma and the possibility of a vascular origin. It has been said that diagnostic images, mainly ultrasound and CT, have a high capacity to get a renal AML diagnosis before the surgery. However when there is an atypical characteristics association like we have talked about, dismissing other pathologies is necessary. We believe AML must be considered one of these because of its difficult differential diagnosis.

Angiomiolipoma renal intrasinusal.Diagnóstico diferencial con el aneurisma de arteria renal / Intrasinusale renal angiomyolipoma. Differential diagnosis with renal artery aneurysm

Presentamos un caso clínico de angiomiolipoma (AML) renal atípico por su forma de presentación como cólico renal, por su localización infrecuente a nivel intrasinusal, por la escasez de su componente graso, pero sobre todo por la confusión diagnóstica con un aneurisma de la arteria renal que no pudo ser aclarada prequirúrgicamente a pesar de la realización de ecografía-doppler, arteriografía renal selectiva, tomografía computerizada (TC) y resonancia magnética (R.N.). Renunciamos a la realización de biopsia percutánea dada la localización, la asociación de hematoma y la posibilidad de un origen vascular.Se ha descrito la alta capacidad de las pruebas de imagen, fundamentalmente de la ecografía y la TC, para el diagnóstico prequirúrgico del A.M.L. renal. Sin embargo, cuando se presenta una asociación de características atípicas como las que se han comentado es necesario descartar otras entidades patológicas. Creemos que entre éstas debe tenerse en cuenta la dificultad de diferenciación con un aneurisma de la arteria renal. (AU)

[Tuberculosis and renal cancer]. / Tuberculosis y cáncer renal.

The association of tuberculosis and renal adenocarcinoma is very uncommon. In general, the condition presents clinically, radiologically and biologically, as a tuberculosis while the diagnosis of renal carcinoma came as a pathoanatomical finding following nephrectomy. We contribute one case report of tuberculosis and renal adenocarcinoma in association that initially presented with tumoral signs and symptoms in a 34-year-old female patient. The patient, with no previous background, was later diagnosed TBC. A review is made on the pathogenesis, epidemiology and pathoanatomical diagnosis of tuberculosis. It is hypothesized that the tuberculosis damage may be a reactivation secondary to a renal tumour.

[Primary abscess of the psoas. Report of a case]. / Absceso primario de psoas. A propósito de un caso.

Psoas abscess is an uncommon condition at the present time. The initial anodyne signs and symptoms make diagnosis difficult. It can be diagnosed and rated as primary when the origin is not found, or secondary when a focus for infection spreading is detected. Drainage either percutaneously or by open surgery, and antibiotic therapy are the choice treatment, achieving an important survival rate. This paper presents a new case of psoas abscess, including a revision of the diagnosis and treatment of this condition.

[Testicular epidermoid cyst]. / Quiste epidermoide testicular.

Epidermoid cysts are benign tumours that can affect testicles. Incidence is rare, having been described until now in less than 200 cases. Contribution of one study case of testicular epidermoid cyst and discussion of issues on histogenesis, ultrasound diagnosis and therapy approaches.

[Paratesticular lipoma]. / Lipoma paratesticular.

In spite of being the most frequent benign tumour of the spermatic cord, absolute frequency of this neoplasia is very low. We discuss here a case report of an spermatic cord lipoma with several years evolution. Although ultrasound is useful for clinical diagnosis, exploratory scrototomy and surgical exeresis of the mass is the only reliable diagnosis and viable treatment.
