Carcinoma renal de istmo en riñón en herradura. A propósito de un caso / Herseshoes kidney isthmus carcinoma. A case report

El riñón en herradura ( RH) es la más común de las anomalías por fusión. La incidencia de carcinoma renal en RH suele ser similar a la del riñón normal. Dadas sus características anatómicas especiales, se deben tener en cuenta para su abordaje quirúrgico, así como para la realización de una posible cirugía conservadora. Presentamos un caso de carcinoma renal en istmo de RH en el que se realizó cirugía conservadora de ambas unidades renales (AU)

Horseshoe kidney is the most frequent fusion abnormality of the kidney. The incidence of renal carcinoma in patients with horseshoe kidney is similar to those with normal anatomy. Its special anatomical features must be borne in mind for both surgical approach and conservative surgery. We present a horseshoe kidney isthmus carcinoma case report in which we performed conservative surgery of both renal units (AU)

Endometriosis vesical: dos nuevos casos / Vesical endometriosis: report of two cases

La endometriosis en el aparato urinario es una patología infrecuente, siendo la vejiga el órgano afecto en la mayoría de las ocasiones. Se manifiesta clínicamente con urgencia, frecuencia, dolor hipogástrico y en ocasiones con hematuria. La cistoscopia es la prueba diagnóstica más fiable aunque el diagnóstico de confirmación es histológico. Presentamos 2 casos de endometriosis vesical en 2 mujeres jóvenes, una con antecedentes de manipulación ginecológica, en las que el tratamiento quirúrgico fue satisfactorio. Tras 1 y 3 años de seguimiento las pacientes permanecen asintomáticas

Endometriosis affecting the urinary tract is very rare and the most common site of involvement is urinary bladder. The clinical features are urgency and frequency, hipogastric pain and hematuria. Cistoscopic examination is the most valuable diagnostic test but definitive diagnosis requires histologic confirmation. We report 2 cases of endometriosis in 2 young women, one with previously cesarean section, in which surgical treatment was effective. After 1 and 3 years of follow-up respectively the patients remain assymptomatic

[Complex renal cyst. A new case]. / Quiste renal complejo. A propósito de un caso.

Approximately 15% of cases of renal cell carcinoma present cystic configuration on radiologic and pathologic examination. These lesions are often difficult to differentiate from the multiloculated renal cyst or other benign cystic lesions such as hemorrhagic cyst and so on. We report a case of multilocular cyst of the right kidney complicated with clear cell type renal cell carcinoma in which MRI suggested benign cyst. The diagnosis of complicated benign cyst must be proposed very cautiously and the persistence of doubtful images justifies surgical exploration.

Quiste renal complejo. A propósito de un caso / Complex renal cyst. A new case

Aproximadamente un 15% de los carcinomas renales presentan un aspecto quístico en las exploraciones radiológicas y estudio anatomopatológico. En ocasiones estos tumores son difíciles de diferenciar de los quistes renales multiloculados u otras lesiones benignas como quistes hemorrágicos. Presentamos un caso de quiste renal complejo en el que la RNM mostró un patrón de quiste simple. El diagnóstico y manejo de estas lesiones debe ser muy cuidadoso y si persisten las imágenes sospechosas está justificada la exploración quirúrgica

[Inguinal bladder hernias. A report of 2 cases]. / Hernias vesicales inguinales. Aportación de dos casos.

Bladder hernia is a very uncommon but not exceptional condition. It tends to occur in adult patients over 50, and is favoured by a cervical-urethral obstruction. It is often diagnosed during inguinal hernia surgery, although in other cases pre-operative diagnosis can be achieved through radiological studies (filling cystography), in patients with urinary signs and symptoms associated to inguinal hernia. Treatment involves the association of herniography and deobstructive surgery at the cervical-urethroprostatic level. The use of a polypropylene mesh [correction of stent] to reinforce a damaged abdominal wall is evaluated and it presents an improved result over the traditional techniques. The excellence acceptance by the body should also be taken into account, as no rejection or infection problems were reported the present cases.

[Malignant fibrohistiocytoma of the spermatic cord. Report of a case]. / Fibrohistiocitoma maligno de cordón espermático. Aportación de un caso.

A case of malignant fibrohistiocytoma of the spermatic cord is described. This rare site of tumor presentation and the histopathological features of this tumor type are briefly discussed. We underscore the importance of treatment by radical orchiectomy.

[Subcapsular renal hematoma: report of a case of unusual etiology]. / Hematoma renal subcapsular: presentación de un caso de etiología inusual.

The authors present a case of myeloproliferative syndrome with an exceptional clinical picture of pain in the right hypochondrium and right iliac fossa, with no mictional syndrome or hematuria, caused by the appearance of a spontaneous subcapsular hematoma. They discuss the frequency of the different kinds of kidney hematomas and their causes. They also describe the typical radiological signs of the subcapsular hematoma in comparison with the other forms of kidney hematomas.
