[Acute renal infarction. Report of 2 cases]. / Infarto renal agudo. Presentación de dos casos.

Diagnosis of acute renal infarction is often delayed or missed due to both the rarity of the disease and its unespecific clinical presentation. Definitive radiologic diagnosis often requires invasive procedures such as angiography. Computed tomography (CT) may be useful in diagnosing acute renal infarction and is considered the standard of reference for diagnosis of acute renal infarction, with the advantage of being non-invasive and potentially available 24 hours a day. We report two cases, in the first case we show a segmentary renal infarction; at the second one we report a case of complete renal infarction. Presentation, diagnosis and therapeutic aspects are discussed.

[Crossed renal ectopy with fusion: report of a case]. / Ectopia renal cruzada con fusión: presentación de un caso.

OBJECTIVE: To present a case of crossed fused renal ectopia that was incidentally discovered in a patient consulting for abdominal pain in the emergency department. METHODS: A 46-year-old patient consulted at the emergency department for abdominal pain. Assessment by diagnostic imaging techniques demonstrated a crossed renal ectopia and associated bone anomalies. RESULTS/CONCLUSIONS: Crossed renal ectopia is an uncommon congenital anomaly and in most of the cases usually presents with fusion of both kidneys. It can also be associated with congenital anomalies of other organs. No treatment is required unless there are other complications or superimposed pathologies.

Infarto renal agudo. Presentación de dos casos / Acute renal infarction. Report of two cases

El diagnóstico del infarto renal agudo es frecuentemente tardío o inadvertido, debido a lo poco común de la enfermedad y a la inespecificidad de su presentación clínica. El diagnóstico radiológico definitivo requiere en ocasiones procedimientos invasivos como la arteriografía. La tomografía axial computerizada (TAC) es útil en el diagnóstico del infarto renal agudo, y es considerada en la actualidad como la técnica de referencia, con la ventaja de ser una técnica no invasiva y estar disponible en cualquier momento. Presentamos dos casos clínicos, uno de infarto renal agudo segmentario y otro de infarto total. Se comentan las técnicas diagnósticas así como el tratamiento y la evolución de los pacientes (AU)

[Hydatidosis in a single location]. / Enfermedad hidatídica de localización única.

Hydatidosis in our country an important health problem because of its high prevalence. We present a case of renal Hydatidosis in which we point out the renal single location of the disease and emphasize that MRI helped us to find a correct preoperative diagnosis.

[The role of urethral catheterization in penile necrosis]. / Papel del sondaje uretral en la necrosis peneana.

Isolated penile necrosis is a rare entity, its main causes are diabetes mellitus and chronic renal failure. Only two cases related with urethral catheterization have been published in the literature. We present a case of penile necrosis in a patient with a Foley catheter, the possible role of the catheter in the etiology and its management are discussed.

[Leydig cell tumor: report of 2 cases]. / Tumor de células de Leydig: presentación de dos casos.

Tumors from the gonadal stroma represent 4% among testicular tumors. Leydig cell tumors are the most common neoplasms among them and account for 1-3% of all testicular tumors. Two cases of testicular Leydig cell tumors in adult patients are presented. Presentation, diagnosis and therapeutic aspects are discussed. Both were treated with radical orchiectomy through an inguinal approach. Cas 1 was diagnosed in a cryptorchid testis and developed hepatic metastasis that were successfully treated with chemotherapy. Cas 2 was incidentally diagnosed on ultrasound. Both of them remain alive and free of disease.

[Candidiasis of the upper urinary tract. Report of a case]. / Candidiasis del tracto urinario superior. A propósito de un caso.

OBJECTIVE: We report a case of candidiasis of the upper urinary tract that presented as acute renal failure associated with septic syndrome. The patient initially required hemodialysis. Right hydronephrosis and perirenal collection were observed on ultrasound examination. METHODS: A percutaneous nephrostomy was performed. Nephrostomy urine cytology and cultures were positive for Candida tropicalis. An anterograde pyelography showed a 'fungus ball' in the urinary tract. RESULTS: Therapy with oral fluconazole and percutaneous amphotericin B achieved excellent results. CONCLUSIONS: Candidiasic urinary infection of the upper urinary tract often produces obstructive uropathy requiring percutaneous nephrostomy, which can also be used to instill amphotericin B. Combination therapy with amphotericin B and fluconazole can achieve excellent results.

[Diagnosis of the composition of urinary calculi based on ions study in blood and urine]. / Diagnóstico de la composición de los cálculos urinarios basado en el estudio iónico en sangre y en orina.

Description of a diagnostic procedure by presumption of urinary calculi composition, based on the comparative statistical study of a group of blood and urine ions which have allowed identification of such composition, with little margin of error, in 264 renal calculi prior to complete fragmentation by extracorporeal lithotrity with pressure waves, and for which it was possible to choose the most suitable cycle and intensity.
