[Are there any differences between the characteristics and the behavior of bladder cancer according to the age of presentation? Our experience]. / Existen diferencias en las caracteristicas y en el comportamiento del tumor vesical según edad de presentación? Nuestra experiencia.

INTRODUCTION: Owing to the different results from the series that evaluate the behavior of the bladder cancer according to the age at the moment of the diagnosis, our objective is based on valuing the characteristics and behaviour according to age of appearance. METHODS: A retrospective study of bladder cancer diagnosed in our area during decade 1993-2003, distributed in 3 intervals of age and some characteristics and behaviour are valued. RESULTS: Elderly patients present greater tumors, non differentiated and with greater rate of progression to infiltrated. Moreover the age, the pathological stage and the tumorlike degree appear as independent significant factors in the multivariant study. CONCLUSIONS: In our experience, the patients greater than 70 years present neoplasms of similar clinical characteristics, although pathologically more aggressive, with greater percentage of progression and worse survival.

[Consults by scrotum mass: epididymo lesions]. / Consulta por masa escrotal: lesiones epidimarias.

In this review we try to update the knowledge about the tumors of epididymis, describing problems in diagnosis and treatment. We present a case of a 39 years old patient who consults by left testicular mass, before the sonogarphy suspect of tumor was made magnetic resonance imaging , wich aimed towards tumorlike injury. Excision of the injury via inguinal was made and the pathologic diagnosis was of adenomatoid tumor. Owing to the few series that appear in literature, and being the commentaries of these tumors about isolated cases, we expose the characteristics of this illustrated case to value the characteristics in diagnosis and treatment to compare them with other cases.

[Incidental prostatic cancer: T1a-T1b. Our experience after observation/radical surgery and literature review]. / Cáncer de próstata incidental: T1a-T1b. Nuestra experiencia tras observación/intervención radical y revisión de la literatura.

OBJECTIVES: To analyse the progress of T1a and T1b prostate cancer diagnosed in our hospital. MATERIAL AND METHODS: Retrospective study of 40 patients in T1a-T1b clinical stage diagnosed with prostate adenocarcinoma in our hospital, from 1986 to 1999. A restaging biopsy was performed on the 16 T1a patients after initial diagnosis and control. A radical prostatectomy was performed on the 24 T1b patients. They were all monitored every six months with rectal exam and PSA. We analysed biological and/or clinical progression, time to progression, mortality caused by the tumour and survival. RESULTS: None of the 16 patients with T1a clinical stage presented tumour progression, with a median follow-up of 90 months. 12,5% of the 24 T1b cases presented tumour progression, with a median follow-up of 70 months. Cancer-specific mortality was one patient (4,16 %) in the T1b group. CONCLUSIONS: Observation and follow-up with PSA and rectal exam appears to be a good option for T1a clinical stage, given the good prognosis. Our results show that patients with T1a clinical stage and good prognostic factors could be at a similar risk of suffering from a new prostate cancer as the normal population, although prospective studies are required to validate these results. T1b cases require active treatment and closer monitoring.

[Papillary carcinoma after 13 years of correct function of renal graft]. / Carcinoma papilar hallado en injerto renal tras 13 años de correcto funcionamiento.

It is known the greater probability appearance of malignancy injuries in patients with renal graft due to its inmunosupresión. We expose a case in which after thirteen years of correct operation of the renal transplant a tumor is diagnosed of accidental form by means of ultrasonography of graft's control. It was demonstrated by percutaneous biopsy that it was a carcinoma to papilar and later transplanctectomy was made. We raised a reflection about the novo tumors on renal graft given to the high number of patients with funcionante transplant during long years and the little evidence in Literature, proposing a possible registry of such valuing its behavior and comparing it with the well-known ones on native kidneys without inmunosupresión situation.

[Treatment of hemorrhagic cystitis secondary to cyclophosphamide. Literature review with regard to a case]. / Tratamiento de la cistitis hemorrágica por ciclofosfamida. Revisión de la literatura a propósito de un caso.

There are extreme situations in the clinical treatment of intractable hematuria (fortunately not a common disease nowadays), in which even benign process may represent a serious risk to the life of the patient and where certain aggressive procedures like cystectomy have to be considered. Our objective in this paper is to review the different existing therapeutic alternatives for the treatment of an intense type of hematuria which does not yield to continuous saline serum irrigation. This study is partly based on a recent real clinical case in which, after the administration of cyclophosphamide to a young patient with recurrent and intense hematuria, the excretion was controlled through intravesical alum irrigation of thus avoiding cystectomy, a very aggressive surgical procedure with many after-effects.

[Post-traumatic hematoma in pathologic kidney]. / Hematoma postraumático en riñón patológico.

We want to present a case of postraumatic hematoma in a tumoral kidney. The diagnosis of the hematoma was made by abdominal scanner but not the tumor type. It was necessary the chirurgycal review and pathological study to demonstrate an angiomyolipoma as the cause of the kidney hematoma.
