[Complex renal cyst. Laparoscopic treatment].

The difference between the simple renal cysts, that doesn't require surgical treatment, and those that need it, sometimes is difficult. The laparoscopic surgical treatment (laparoscopic cyst decortication -laparoscopic partial nefrectomy or radical laparoscopic nefrectomy) its becoming the gold standard technique, recommending this procedure in Bosniak cyst type III or IV, and in the symptomatic renal cyst type I/II and in any patients with Bosniak cyst renal II. We present a case report in which a renal cell carcinoma was found after laparoscopic cyst decortication of Bosniak cyst type II with laparoscopic radical nefrectomy posteriorly.

[Unilateral agenesis of structures dependent on the mesonephric duct. Presentation of a case].

The mesonefric duct plays an essential role in the development of the genitourinary tract. From that duct derive structures as the ureter, the vas deferens and the seminal vesicles. Also, the ureteral bud interact with the mesonefric blastema and induce its conversion to renal tissue. The origin of these anomalies of the embrionary development is unknown. In some cases, mutations on the gene of the cystic fibrosis (CFRT) could play a role, assuming that there is a relationship between the congenital absence of the vas deferens and the cystic fibrosis. Usually, the absence of these structures has a silent course. Thus, the most important diagnostic factor is the clinical suspicion. The knowledge of this association can lead to the diagnosis of other congenital abnormalities. In addition, it is important to know that these anomalies could be present isolated as expression of other non-urological diseases, specially the cystic fibrosis, the most common hereditary disease between the Caucasian race.

[Localized sarcomatoid renal carcinoma. Which factors may predict its course?].

Sarcomatoid renal carcinoma constitutes an uncommon variant of renal carcinoma. Typically its behaviour is more aggressive than other forms of renal carcinoma and usually it is diagnosed at advanced stages. The main prognostic factor is the clinical stage at the time of the diagnosis. However, some cases initially are diagnosed at low stages having a poor prognosis, probably because there are other factors than the clinical stage which determinate its outcome. We report a case of sarcomatoid renal carcinoma confined inside the kidney capsule at the time of the diagnosis which had a rapidly bad progression. We review the characteristics of this tumour variant and analyse what factors, basically histological, could be helpful to predict its evolution.

[Usefulness of the dynamic sentinel node technique in patients with penile carcinoma].

OBJECTIVE: To explain and analyse when and how to use the new staging technique used in patients with squamous carcinoma of the penis, through the procedure of dynamic biopsy of the sentinel lymph node. PATIENTS AND METHODS: We demonstrate the technical application of the dynamic biopsy of the sentinel lymph node, in a 40-year-old patient, diagnosed as suffering from squamous carcinoma of the penis. We use preoperative lymphatic visualization through lymphogammagraphy, together with intraoperative detection through gamma scanning, in order to detect and identify the sentinel lymph node. CONCLUSIONS: We consider the dynamic biopsy of the sentinel node by the individual pattern of the lymphatic drainage as a new applicable Nuclear Medicina technique. It is an extremely useful technique in order to achieve early dissemination, by allowing us to identify patients with sub-clinic lymphatic spread, who will be candidates to regional lymphatic dissection.

[Primary retroperitoneal hydatidosis].

Genitourinary involvement by the Echinococcus granulosus larvae (urinary hydatidosis) ranks third in order of frequency after liver and lung involvement. The finding of a primary hydatidic cyst with retroperitoneal location is an uncommon fact. This paper presents once case of this infrequent disease. A revision of the different etiopathogenic mechanisms, as well as diagnostic and therapeutic approaches is made.

[Small cell carcinoma of the bladder. Report of a new case and review of the literature].

Small cell carcinoma of the bladder is a rare entity occurring in fewer than 1% of all the primary bladder tumors. Its clinic and epidemiologyc characteristics are similar to the transitional cell carcinoma. But, its more aggressive with a high tendency to infiltrate the muscular layer and to metastasize. Thus, therapeutic approach used by the pulmonary form has been applied to the bladder carcinoma. The best results has been achieved using systemic chemotherapy, not only in survival rates but in preserving the bladder integrity, playing the radical cystectomy a rescue role in cases of recurrence or persistence of the tumor. We report a new case of small cell carcinoma of the bladder and review the literature with special attention to the different therapeutic approaches.
