Treatment of urachal disorders: The open and laparoscopic surgery approach.

Introduction: The present study analyzes cases of urachal abnormalities treated with laparoscopic approach in our hospital.

Case Description: A retrospective descriptive study of urachal disorders with laparoscopic surgery approach performed at our hospital in the period 1999-2015. Patients' clinical data are presented (radiological findings, surgical data, pathology findings, complications and a follow-up of each patient).

[Hospital incidence, trends and municipal distribution of prostate cancer in health area of León, Spain (1996-2010)].

Background: Prostate cancer (PC) is the most prevalent among men and yet its risk factors are little known. This article aims to determine the hospital incidence, trend and municipal distribution of PC in Health Area of León (HAL).

Methods: We included new cases of prostate cancer (ICD-9: 185, ICD-10: C61) enrolled in the Hospital Tumor Registry of the Complejo Asistencial Universitario de León, between 1996 to 2010 with residence in HAL.

Perioperative complications and surgical oncology outcomes in an initial study from 84 patients submitted to laparoscopic radical cystectomy.

Objectives: The Gold Standard treatment for a non-metastatic, invasive bladder cancer is an open radical cystoprostatectomy (ORCP). Laparoscopic radical cystoprostatectomy (LRCP) is still an experimental technique in evaluation. We describe our perioperative results defined as surgical and safety oncology variables.

[Cholesterol embolism of the upper urinary tract as a clinical feature of atherosclerotic embolic vascular disease. Report of three cases, one of them simulating neoplasia].

Objectives: To report three cases of atherosclerotic embolic vascular disease with clinical presentation in the lower urinary tract. This disease is not frequent; it mainly affects the skin, kidneys and skeletal muscle. Other organs of the urinary tract are rarely affected and they are exceptionally the clinical site of debut without previous known involvement of other areas.

[Penile silicone granuloma].

Objectives: To report our experience with one case of penile silicone granuloma, that has clinical interest for its unfrequent presentation.

Methods/results: We report the case of a patient with sexual dysfunction secondary to subcutaneous injection of liquid silicone in the penis resulting in a penile granuloma and migration of the particles to the penile root and midline scrotal raphe. We proceeded to the surgical excision of the granuloma and migrated particles, repairing the penile defect with scrotal skin.

[Renal malacoplakia: report of a new case].

Objectives: Malacoplakia is a chronic granulomatous disease which can involve different areas of the body, being the genital renal system the most frequent site. We describe a case of unilateral renal malacoplakia.

Methods/results: We report the case of a female patient with the clinical working diagnosis of renal cell carcinoma that required drainage of a homolateral abscess which cultured positive for E.

Lymphoepithelioma-like carcinoma of the bladder: three cases with clinicopathological and p53 protein expression study.

Lymphoepithelioma-like carcinoma of the bladder is an uncommon neoplasm, of which 49 cases have been described in the English literature, none of which has been studied for p53 protein expression. We studied three muscle-infiltrating cases of this tumor using immunohistochemical, in situ hybridization and polymerase chain reaction (PCR) methods. The three cases were positive for epithelial markers and negative for lymphoid antigens in the tumoral syncytial areas.
