Benign renal schwannoma: Case report and literature review.

Renal schwannoma is a very infrequent tumor. It is usually benign and it does not have any specific symptoms or imaging characteristics. Its final diagnosis is usually made after surgery. We present a 66 year-old-man that was referred to our center after the casual finding of a renal mass. With a suspected diagnosis of a renal cell carcinoma, a partial nephrectomy was performed. The histological study revealed the final diagnosis of a benign renal schwannoma.

Bacillus Calmette-Guérin in Immunosuppressed Patient with High-Grade Nonmuscle Invasive Bladder Carcinoma.

Due to their immunosuppressed status, solid organ transplant recipients are a special group of patients with an incidence of bladder cancer greater than the rest of the population, especially in the first 6 years after transplantation. Also, treatment with Bacillus Calmette-Guérin, a reference therapy in nonmuscle invasive high-risk bladder cancer, may be less effective in this group of patients and could cause more adverse effects. However, the data published so far and the experience initiated in the Virgen de la Arrixaca Clinical University Hospital do not support these hypotheses.

[Recurrent urinary tract infections: prevention of recurrence with intravesical instillations of chondroitin sulfate and hyaluronic acid.] / Infecciones urinarias de repetición: prevención de recidivas con instilaciones intravesicales de condroitin sulfato sódico y ácido hialurónico.

OBJECTIVE: The aim of our study is to demonstrate that intravesical administration of the association chondroitin sulfate (CS) and hyaluronic acid (HA), according to our treatment schedule, is a benefit for women with recurrent urinary tract infections (RUTI), not only from a clinical point of view, but also reducing recurrences. METHODS: This is a study of 28 women diagnosed with RUTI, with a positive culture, and compatible symptoms;frethey underwent treatment according to the protocol of intravesical instillations of the combination CS 2%-1 gr + HA 1.6%-800 mg. To evaluate the effectiveness of the treatment, symptoms improvement, reduction of the number of episodes of urinary tract infection and quality of life were considered. RESULTS: In our series, we can observe an improvement of the quality of life assessed by PG-I, 66% after 12 months. It was seen that 55.6% of the patient's urine cultures became negative, while 44.4% had episodes of urinary infection, but with lower baseline symptoms intensity. DISCUSSION: Patients included in the protocol of instillation improved significantly their quality of life; in addition, to a considerable extent new urinary infections were not presented, being milder when they presented.

OBJETIVO: El objetivo de nuestro estudio es demostrar, que la administración intravesical de la asociación condroitin sulfato sódico (CS) y ácido hialurónico (AH) según nuestro esquema de tratamiento, supone un beneficio en mujeres pre/post menopáusicas con infecciones urinarias de repetición (IUR), no sólo desde el punto de vista clínico, sino que también disminuyen las recurrencias. MÉTODOS: Se presenta un estudio con 28 mujeres diagnosticadas de IUR con cultivo positivo y síntomas compatibles, siguieron tratamiento según protocolo de instilaciones intravesicales de la combinación CS 2%-1 gr + AH 1,6%-800 mg (IALURIL®). Para comprobar la eficacia del tratamiento se evaluó: mejoría de síntomas, reducción del número de episodios de infección urinaria y la calidad de vida. RESULTADOS: En nuestra serie se apreció una mejoría de la calidad de vida, valorada por la escala de impresión de mejoría global del paciente (PG-I), a los 12 meses del 66%. Se apreció que el 55,6% (15/27) de las pacientes negativizaron sus cultivos, mientras que el 44,4% (12/27) presentaron un solo episodio de infección urinaria pero con menor intensidad de síntomas que al inicio del estudio. CONCLUSIONES: Los pacientes incluidos en el protocolo de instilación mejoraron de forma significativa su calidad de vida, además en un porcentaje considerable no se presentaron nuevas infecciones urinarias; en los casos que se presentaron estas fueron menos frecuentes y afectaron menos el estado general de las pacientes que pretratamiento

Must we still be worried about multiple arteries in kidney transplantation?

BACKGROUND: Multiple renal arteries in kidney grafts have been associated with an increased rate of vascular and urologic complications. Our objective is to compare the outcome of transplanted patients who receive a single pedicle kidney with those who receive a multiple arterial graft. OBJECTIVES: To find our the differences in the outcome and complications in patients undergoing kidney transplantation with one single artery or with multiple arteries. PATIENTS AND METHODS: We analyzed 147 kidney transplantations, (all performed in our hospital over a 3 year period). population divided into two groups: group A for those who presented with only one renal artery, or group B for those with more than one renal artery. Homogeneous vascular reconstructions and implantation rules were applied in all patients. We compared the rates of renal failure between the two groups, urinary and vascular complications, patient and graft survivals and the levels of creatinine clearance during the first year of post-transplantation. RESULTS: No significant differences were found between the two groups regarding to the values analyzed. CONCLUSIONS: As many other authors, we do believe that the presence of multiple renal arteries in kidney grafts should not be considered as a predictive factor of transplantation failure.
