[[Greenlight-XPS laser vaporization, the new standard of treatment in men with myasthenia gravis and benign prostatic obstruction]?].

Unlabelled: Patients with Benign Prostatic Obstruction (BPO) and Myasthenia Gravis (MG) treated with Transurethral Resection of the prostate (TURP) show a high incidence of urinary incontinence due to unnoticed damage to muscle fibres of the external sphincter. Photoselective laser vaporization could be an alternative treatment based on the hypothesis that using Laser as energy source in the treatment of BPH prevents sphincter damage because the energy is not transmitted outside the fiber tip.

Methods: We report the case of a man diagnosed of MG and symptomatic BPO treated satisfactorily with photoselective laser vaporization (GreenLight-XPS).

Is there a role for systemic targeted therapy after surgical treatment for metastases of renal cell carcinoma?

Metastatic renal cell carcinoma (mRCC) is a challenging disease. Despite the new targeted therapies, complete remissions occur only in 1%-3% of the cases, and the most effective first-line treatment drugs have reached a ceiling in overall survival (ranging from 9 to 49 mo). Metastasectomy remains to be the only curative option in most patients with mRCC.

[Urethral stricture in women].

Unlabelled: To perform a bibliographic review on female urethra stenosis, following the criteria for evidence based medicine.

Methods: We performed a PubMed Search with the following keywords; "female urethral stricture ","women urethral stricture","female urethral reconstruction "and " female urethral stricture treatment ",without time limits, both in English and Spanish languages.

Results: Female urethra stenosis is a rare pathology, in which the working diagnosis is essential, as much as detailed physical examination, urodynamic study and radiological tests.

Prognostic factors in patients with stage pT0/pT1/pTa in the radical cystectomy specimen.

Objectives: To identify risk factors for progression in patients with invasive bladder carcinoma who were pT0/pT1/pTa after cystectomy.

Methods: We analyzed the clinical records of 97 post-cystectomy pT0/pT1/pTa patients for the following variables: hydronephrosis, carcinoma in situ (CIS), lymphovascular invasion, history of non-muscular invasive disease, residual tumor in the specimen and lymphatic invasion (pN). pN+patients were excluded from definitive analysis.

Urachal adenocarcinoma. Case report and bibliographic review.

Objective: Literature review of adenocarcinoma of the urachus in connection with two cases recently diagnosed and treated in our center.

Methods/results: We report 2 cases of urachus Adenocarcinoma treated in our institution, both underwent extended partial cystectomy including excision of the urachus up to the umbilicus.

Conclusion: Urachal adenocarcinoma is an exceptional tumor, of poor prognosis, the treatment of which is surgical (partial cystectomy), and the main predictors of disease-free survival are the degree of tumor differentiation and the free margins of the surgical specimen.

[Rescue cryotherapy for prostate cancer after radiotherapy].

Radical Radiotherapy constitutes a useful therapeutic option for localized prostate cancer. Almost one third of prostate cancer patients choose this alternative to treat the disease. Despite modifications in the technique as intensity modulation, 3D conformational radiotherapy or computer-assisted brachytherapy, a significant percentage of these patients will show an increase in PSA values after radiation.

Primary renal Ewing's sarcoma.

Objective: To report two new cases of Ewing's sarcoma/primitive neuroectodermal tumor of the kidney, one of them with tumor thrombus in cava.

Method: Characterization of two new cases and literature review by PubMed search.

Results: We report the cases of two men diagnosed with primary renal Ewing's sarcoma, who have been treated with nephrectomy and adjuvant chemotherapy, being in complete remission to date.

First percutaneous computed tomography-guided radiofrequency ablation of renal tumor in horseshoe kidney.

Objective: To report the first case of percutaneous radiofrequency ablation of a tumor in a horseshoe kidney.

Materials And Methods: A 75-year-old man presented with a 3-cm solid mass on the isthmus of a horseshoe kidney. The tumor was discovered incidentally on a routine computed tomography scan performed during follow-up of a colon carcinoma treated with open hemicolectomy.

Villous adenoma in augmentation colocystoplasty asociated to infiltrating urotelial cancer in bladder remanent.

Objective: To report a new case of villous adenoma developed in augmentation colocystoplasty.

Methods: Characterization of a new case and review of the literature published to date.

Results: We report the case of a 66 year-old man with a villous adenoma and synchronic infiltrating transitional cell carcinoma of the bladder after augmentation colocystoplasty.
