Objective: To create a simple, inexpensive, and reproducible animal model to provide a new training option for performing urethrovesical anastomosis during laparoscopic radical prostatectomy.
Material And Methods: Development and testing were carried out in 2008. The materials used included a laparoscopic training box, video camera, monitor, needle holder, sutures, and non-eviscerated chickens weighing more than 2 kilograms.
Objectives: To report the first case and detailed technique of laparoendoscopic single-site (LESS) surgery simple prostatectomy for benign hypertrophy.
Methods: A 67-year-old man presented with acute urinary retention requiring catheterization. Serum prostate-specific antigen level was 5 ng/mL, and a biopsy revealed benign hypertrophy with a transrectal ultrasound volume estimation of 110 mL.
Background: Natural orifice translumenal endoscopic surgery (NOTES) has been used to perform nephrectomy in the laboratory; however, clinical reports to date have used multiple abdominal trocars to assist the transvaginal procedure.
Objective: To present our stepwise technique development and the first successful clinical case of NOTES transvaginal radical nephrectomy for tumor with umbilical assistance without extraumbilical skin incisions.
Design, Setting, And Participants: The four transvaginal NOTES procedures were performed at two institutions after obtaining institutional review board approval.
Objective: Primary extragonadal germ cell tumors are rare and their histogenetic origin is not clear. We describe two cases presenting as primary retroperitoneal germ cell tumors without clinical evidence of testicular tumor.
Methods: A 21 and 18 years-old patients presented retroperitoneal choriocarcinoma and yolk sac tumor, respectively.
Objectives: We report herein the clinical, histological, and immunohistochemical features of a case of sarcomatoid chromophobe renal cell carcinoma.
Methods/results: A 59-year-old woman referred a two-month history of constant right flank pain, and hematuria. A right radical nephrectomy was performed.
Objective: We describe the clinical, histological and immunohistochemical studies in a case of extramammary Paget's disease localized in the scrotum with lymph node inguinal metastasis.
Methods/results: A 80-year old man consulted with a one-year history of a pruritic erythematous skin rash of the scrotum. Physical examination showed demarcated erythematous lesion involving the scrotum and right inguinal adenopathy.
Cellular pseudosarcomatous fibroepithelial stromal polyp is an underrecognized lesion described in the lower female genital tract. We here report the clinical, histological, and immunohistochemical features of a cellular pseudosarcomatous fibroepithelial stromal polyp located in the renal pelvis. A 47-year-old woman was referred with a 4-month history of left flank pain and gross hematuria.

Methods/results: A 68-year old man consulted with a two-year history of increasing urinary outflow obstruction that developed into acute urinary retention.
Objectives: The present study reports the clinical and histological features of 14 cases of prostate adenocarcinoma coupled with their expression of the TGF isoforms beta2 and beta3, as well as their receptor endogline (CD105).
Methods: Fourteen (14) cases of adenocarcinoma (ADC) of the prostate were examined. Relevant clinical data were gathered From the histological point of view, the tumor's grade and the evidence of perineural, vascular and/or lymphatic invasion were the key elements taken into account.
Objective: We emphasize the good results obtained by authors of the United States of North America and Europe using prostate brachytherapy in the treatment of localized prostate cancer.
Methods: We report 50 patients with stage T1c-T2c treated during the last twenty one months (September 2000, June 2001). Two groups were made--according to Gleason, PSA, local infiltration and percentage of tumor volume in the Biopsy--in low and high risk patients.
