Female idiopathic Urethra Tumor: clinical features diagnosis and treatment
Zhonghua wai ke za zhi [Chinese journal of surgery], 1996Co-Authors: Sun G, Ma TAbstract:Female idiopathic Urethra Tumors are reported rarely. We treated fourteen patients patients, and described the clinical manifestations and local features of the Tumors, Urethra liomyoma, and fibropolypus. We found that there are close relations among Tumor stage, prognosis and pathological classification. The main diagnostic methods include vaginal touch, urethroscopy, B-ultrasound exam and biopsy. The diagnostic procedure recommended is Tumor location-quality-stage or a three-step method. The main treatment is operation, however, the operative mode should depend on Tumor stage and patient's life quality after operation.

Construction and Evaluation of an Anatomically Correct Multi-Image Modality Compatible Phantom for Prostate Cancer Focal Ablation
Journal of Urology, 2010Co-Authors: Uri Lindner, Nathan Lawrentschuk, Robert A. Weersink, Orit Raz, Eugen Hlasny, Marshall S. Sussman, Sean R.h. Davidson, Mark R. Gertner, John TrachtenbergAbstract:Purpose: Focal therapy using lasers is emerging as an alternative strategy for prostate cancer treatment. However, to our knowledge no anatomically correct models are available to test imaging and ablation techniques. Animal models present ethical, anatomical and cost challenges. We designed and validated an inexpensive but anatomically correct prostate phantom incorporating Tumor, rectum and Urethra that can be used for simulated and experimental magnetic resonance guided focal intervention. Our secondary aim was to asses the phantom using other imaging modalities.Materials and Methods: The phantom, which was constructed of ballistic gel, includes an 80 gm prostate with Urethra, Tumor, perineum and rectum. Gadolinium was added to make the gel visible to magnetic resonance imaging. To recreate a Tumor an irregularly shaped 5 cc volume of coagulable gel was inserted into the prostate phantom. The phantom was evaluated using magnetic resonance, computerized tomography and transrectal ultrasound. Thermal abl...

Mixed squamous epithelial and adenocarcinoma of the female Urethra. A case report
Der Urologe A, 2000Co-Authors: C Reek, Markus Graefen, Joachim Noldus, S. FernandezAbstract:We report a case of mixed squamous-cell carcinoma with adenocarcinoma of the female Urethra. A 37 year old women who presented with a 3-month' history of obstructive voiding symptoms. Clinical investigation showed a Urethra Tumor of 2.5 x 3.5 cm. Needle biopsy revealed a grade 3 carcinoma. Staging resulted in local cancer disease, a 2.5 x 3.5 cm Tumor surrounding the whole Urethra with protruding the trigonum. We performed urethrectomy with resection of the bladderneck and cystoneostomy. During bladderneck resection we performed regional staging lymphadenectomy of the obturator lymph nodes. Histological investigation revealed a mixed squamous-cell carcinoma with adenocarcinoma and undifferentiated carcinoma of the Urethra. PeriUrethral tissue showed lymphangiosis carcinomatosa with negative lymph nodes. To exclude involvement of regional superficial lymph nodes we subsequently performed modified inguinal lymphadenectomy without evidence of advanced cancer disease.

Gemischtes Plattenepithel- und Adenokarzinom der weiblichen Urethra
Der Urologe A, 2000Co-Authors: C Reek, Markus Graefen, Joachim Noldus, S. FernandezAbstract:Wir berichten über den seltenen Fall eines gemischten Plattenepithel- und Adenokarzinoms der weiblichen Urethra bei einer 37 jährigen Frau die sich mit obstruktiven Miktionsbeschwerden und akutem Harnverhalt in der Urologischen Ambulanz vorstellte. In der transvaginalen Biopsie wurde histologisch ein undifferenziertes Karzinom (Grad 3) nachgewiesen. Das Staging ergab einen 2,5 × 3,5 cm großen, die gesamte Harnröhre ummauernden Tumor mit Pelottierung des Blasenbodens. Da das Staging keinen Anhalt für eine Metastasierung ergab, führten wir eine Urethrektomie mit Resektion des Blasenhalses und Anlage einer kontinenten Zystostomie durch. In gleicher Sitzung wurde eine Lymphadenektomie der Obturatoriuslymphknoten beidseits durchgeführt. In der histologischen Untersuchung zeigte sich ein gemischtes Plattenepithel- und Adenokarzinom mit Anteilen eines großzellig undifferenzierten Karzinoms der Urethra mit herdförmiger Lymphangiosis carcinomatosa. Zum Ausschluß einer Beteiligung der oberflächlichen regionalen Lymphknoten, wurde eine beidseitige modifizierte inguinale Lymphadenektomie durchgeführt, die keinen Anhalt für eine lymphogene Metastasierung zeigte.
