[Leydig cell tumor: our experience. Bibliographic review].

OBJECTIVES: To report the case-series of Leydig cell tumors diagnosed at our center, and to perform a bibliographic review on the topic. METHODS: Retrospective review of the clinical records of all patients with the diagnosis of Leydig cell tumor in our center over the last 12 years. We evaluated the clinical, diagnostic and therapeutic features, as well as outcomes. RESULTS: Four patients were diagnosed and treated in our department over this period. Mean patient age of the time of diagnosis was 51 years. Each of our cases have a different presentation. The two patients who underwent sperm analysis had azoospermia. None of the cases showed anomalous hormonal studies. Seventy-five percent of the cases showed ultrasound signs compatible with testicular neoplasia. In all of them surgical treatment was undertaken (inguinal orchyectomy); one of the patients underwent chemotherapy due to metastasis, having a good response. Mean follow-up is 76 months. CONCLUSIONS: It is a rare testicular tumor. Inguinal orchyectomy is the treatment of choice. Its good outcome is remarkable.

[Bladder leiomyosarcoma. Case report].

OBJECTIVE: We report a new case of bladder leiomyosarcoma in a young female patient. We review its features and different treatment options. METHODS: The patient underwent neoadyuvant chemotherapy and surgical excision. RESULTS: A partial response was achieved with neoadyuvant chemotherapy and remains still alive 60 moths after radical cystectomy CONCLUSION: Despite the poor prognosis of this disease, multimodal treatment may improve results. Neoadyuvant chemotherapy and subsequent radical excision could be a good combination therapy for these aggressive tumors.

[Selective embolization in the treatment of severe renal injury].

OBJECTIVES: We report a new case of severe renal trauma with significant active bleeding and urinary tract lesion in a hemodynamically stable patient, emphasizing the option of conservative treatment with selective embolization of the bleeding segmentary renal arteries, and stenting of the urinary tract with retrograde insertion of a JJ stent; thus avoiding emergency surgery associated with a high risk of nephrectomy. We review the indications of this therapeutic option. METHODS: Embolization of bleeding segmentary renal arteries and retrograde insertion of a JJ stent in a 24 year old patient presenting with severe renal trauma after motorbike motor vehicular accident. Patient remained hemodynamically stable during the whole diagnostic and therapeutic process. Good clinical outcome after 72 hours of ICU control and 18 days of admission in the Urology ward. RESULTS: After selective embolization bleeding stopped immediately; significative hematoma resorption and urinary fluid collection disappearance was seen during a 3 week hospital admission. There were not either immediate or deferred complications, being both renal function and blood pressure normal after 18 months follow up. CONCLUSION: Embolization of the bleeding segmentary renal arteries after severe renal trauma in hemodynamically stable patients is a therapeutic option that allows avoiding emergency surgery, which is associated with high risk for nephrectomy. Urinary tract stenting is enough for a good outcome of the pyelocalicilar system.

[Migration of an intrauterine contraceptive device into the urinary bladder: report of one case].

OBJECTIVES: To report one case of uterine perforation and migration into the urinary bladder of an intrauterine contraceptive device. METHODS/RESULTS: 42-year-old female patient who presents with lower urinary tract irritative syndrome in association to recurrent urinary tract infection. Ultrasound revealed apart of an intrauterine device inside the bladder, device which was inserted years before and was supposed to have come out spontaneously. Urethrocystoscopy with extraction of the intravesical segment and hysteroscopy with extraction of the intrauterine segment were carried out. CONCLUSIONS: The postoperative period was satisfactory and patient is currently asymptomatic. Radiological or ultrasound controls should be performed in the follow-up of patients with intrauterine contraceptive devices. The inability to locate an intrauterine contraceptive device in a patient who did not realize it coming out should be considered an uterine perforation until proved otherwise.
