[Prostatic sarcoma: Report of two cases].

Prostatic sarcomas are very rare tumours with a very poor prognosis. They may coexist with prostatic adenocarcinoma, in which case they are only diagnosed on histological examination of the operative specimen with identification of sarcoma on immunohistochemical analysis. Due to their rapidly invasive potential, they must be detect early in the course, particularly in young subjects.

[Laparoscopic partial nephrectomy: A series of 17 cases].

Objective: The objective of this study was to evaluate the Feasibility, the morbidity and the carcinologic results of laparoscopic partial nephrectomy.

Material And Methods: Between August 2001 and December 2005, 17 partial nephrectomies were performed by laparoscopy in patients with a mean age of 59.2 years.

[Post-traumatic renal arteriovenous fistula discovered after 28 years].

There is only one published case of arteriovenous fistula discovered 20 years after firearm trauma. The authors report the case of a 47-year-old man injured by firearm 28 years ago presenting with a highflow aneurysm of the right renal artery secondary to arteriovenous fistula and associated with lower pole renal tumour and describe the radiological work-up and surgical management.

[Pseudoneoplastic form of Chlamydia trachomatis epididymo-orchitis: a case report].

Pseudoneoplastic Chlamydia trachomatis epididymo-orchitis is a rare clinical entity. The differential diagnosis with malignant tumour of the testis remains difficult and surgical exploration with orchidectomy is often difficult to avoid. Urgent testing for Chlamydia trachomatis by PCR in urine, semen and a urethral swab confirms the diagnosis and allows introduction of antibiotic therapy rather than surgical exploration.

[Epidemiology of prostate cancer in the Limousin area].

Objective: Prostate cancer is the commonest cancer in men in France, and its incidence increases with age. It occupies 4th place in terms of mortality. The Limousin region, with the oldest population in France, established a regional registry of new cases of cancers in 1998.

[Role of uropontin in calcium oxalate lithogenesis].

The formation of calcium oxalate stones involves four phases: nucleation, growth, aggregation and retention. Stone formation is a complex, multifactorial phenomenon involving, among other factors, proteins, some of which play an inhibitory role, while others play a promoting role. The authors studied the role of uropontin.

[Cystocele].

A cystocele is a bladder hernia through the anterior wall of the vagina. It is common in elderly women. There is no clinico-anatomical correlation, but the functional disturbance, although both variable and variably experienced, remains a major factor in the indication of eventual surgery.
