Traumatismo renal con urinoma / Renal traumatism with urinoma

El extravasado de orina ocurre en los traumatismos renales que interesan la vía urinaria. El mecanismo de producción del traumatismo, la clínica y la exploración física permiten limitar el diagnóstico a la región lumbar o extenderlo a otras regiones, pero la determinación de la presencia de urinoma precisa de otros métodos. La TC es la mejor prueba diagnóstica aunque en la fase inicial del traumatismo puede no demostrar fuga de contraste. En aquellos casos en que el paciente está inestable, en las lesiones penetrantes o ante una lesión vascular sangrante, debe optarse por la técnica más resolutiva

The leak out of urine occurs in renal traumatisms that affect the urinary system. The mechanism of production of the traumatism, clinic and physical exploration allow to limit the diagnosis to the lumbar region or extended it to other regions, but the determination of the presence of urinoma requires other methods. CT is the best diagnostic test although in the initial phase of the traumatism may not show leakage of contrast. In the cases where the patient is unstable, or in cases of penetrating injuries or in a vascular bleeding injury, we should adopt a more resolutive technique

[Paraurethral cyst of the Littre's gland: an exceptional case]. / Quiste parauretral de la glándula de Littré, un caso excepcional.

OBJECTIVE: To report one case of paraurethral cyst in the male, located in the subglandular penile urethra, an extremely rare pathology. METHODS/RESULTS: 46-years-old male patient with the diagnosis of Littre's gland paraurethral cyst. Diagnosis and subsequent treatment. CONCLUSIONS: Paraurethral cysts of non traumatic origin are very rare, only two cases are described in the literature, one cyst located at the penoscrotal angle dependent from the corpus spongiosum without connection to the urethra, and another case of inflammation of the periurethral Littre's glands simulating a tumor.

Quiste parauretral de la glándula de Llitré, un caso excepcional / Paraurethral cyst of the Littre´s gland: an exceptional case

OBJETIVO: Describir un caso clínico de un quiste parauretral en un varón, a nivel de uretra peneana subglandar, patología extremadamente infrecuente. MÉTODO/RESULTADO: Paciente varón de 46 años de edad diagnosticado de un quiste parauretral de la glándula de littré, su diagnóstico y posterior tratamiento. CONCLUSIÓN: Los quistes parauretrales de origen no traumático son muy raros, sólo se han descrito dos casos en la literatura, un quiste localizado en ángulo penoescrotal dependiendo de cuerpo esponjoso sin conexión con la uretra y otro caso de inflamación de las glándulas periuretrales de Littré simulando un tumor

Embolization of a bleeding aneurysm in a patient with spontaneous perirenal haematoma due to Polyarteritis nodosa.

OBJECTIVE: To report a rare case of a Spontaneous perirenal haematoma due to Polyarteritis nodosa treated with a selective embolización of the bleeding aneurysm. Polyarteritis nodosa (PAN) is one of a spectrum of diseases thet belongs to the pathologic category of necrotizing vasculitis. Spontaneous perirenal haematoma (SPH) is an unusual complication of PAN. METHODS: We are introducing a patient with SPH due to PAN. RESULTS: The patient was treated with embolization of a left renal bleeding aneurysm of the upper interlobar artery. Pan is the most frequent vascular disease associated with spontaneous renal hematoma. Therefore the diagnosis may be difficult to determine. CONCLUSIONS: A selective embolization of the bleeding aneurysm is a therapeutical maneuver to be considered.

Embolization of a bleeding aneurysm in a patient with spontaneous perirenal haematoma due to polyarteritis nodosa

OBJETIVOS: Presentar un caso raro de hematoma perirenal espontáneo secundario a poliarteritis nodosa tratado mediante embolización selectiva del aneurisma sangrante. La Poliarteritis nodosa (PAN) es parte de un espectro de enfermedades que pertenece a la categoría patológica de las vasculitis necrotizantes. El hematoma perirenal espontáneo es una complicación infrecuente de la PAN. MATERIAL Y MÉTODOS: Presentamos un caso de hematoma perirenal espontáneo secundario a PAN. RESULTADOS: Se realizó embolización de un aneurisma sangrante de la arteria renal interlobar superior izquierda. La PAN es la enfermedad vascular que con mayor frecuencia se asocia con hematoma renal espontáneo. Por lo tanto, el diagnóstico puede ser difícil de establecer. CONCLUSIONES: La embolización selectiva del aneurisma sangrante es una maniobra terapéutica a considerar

Is bladder cycling useful in the urodynamic evaluation previous to renal transplantation?

OBJECTIVES: To evaluate the usefulness of bladder cycling (BC) in differentiating between urodynamic abnormalities due to reversible bladder dysfunction and those due to preexisting lower urinary tract (LUT) abnormalities, and to determine if BC increases the diagnostic yield of urodynamic investigations (UIs) in these patients. METHODS: Eleven patients with oligoanuria (<300 ml/day) were evaluated with complete UIs. All cases showed low compliance (mean 6 ml/cm H2O) and low cystometric capacity (mean 146 ml) and were placed in a BC program. The indications for UIs were LUT symptoms in 2 patients, LUT abnormalities (myelodysplasia or urethral valves) in 3 patients, or the appearance of an extremely small bladder on cystogram (6 patients). BC was performed through a hypogastric catheter in an outpatient setting. UIs were repeated afterwards. RESULTS: After BC, 5 patients (45%) continued to have low compliance (<8 ml/cm H2O) and 4 patients (36%) had normal UIs. In 2 cases (18%), a previously unrecognized obstruction was diagnosed. No patient with LUT symptoms or abnormalities had a normal UI after BC. Conversely, 4 of 6 patients in whom BC was indicated due to a small bladder on cystogram had normal UIs after BC. CONCLUSIONS: BC is useful in explaining whether high bladder pressure is due to dysfunction or to preexisting disorders, and thus indicating the proper surgery for correction. Suprapubic BC significantly increases bladder capacity thus increasing the diagnostic yield of the UI.
