[A case of urothelial carcinoma with trophoblastic differentiation and review of the literature].

We report the case of a 43-year-old woman, who was admitted for intense pelvic pains. Biological investigations showed an increase of β-HCG level. The abdomino-pelvic computed tomography revealed a voluminous mass infiltrating the bladder.

A switch from GnRH agonist to GnRH antagonist in castration-resistant prostate cancer patients leads to a low response rate on PSA.

Purpose: At the time of castration resistance, it is recommended to realize hormonal manipulations before chemotherapy. We evaluated the impact of a switch from GnRH agonist to antagonist in patients with castration-resistant prostate cancer on PSA and testosterone levels at 3 months.

Methods: Retrospectively, 17 patients from 5 different centers undergoing androgen deprivation therapy and presenting rising PSA confirmed on 3 blood samples 2 weeks apart and despite a castrate testosterone level (<0.

Helical CT and 3D reconstruction of ureteropelvic junction obstruction: accuracy in detection of crossing vessels.

Purpose: The purpose of our study was to evaluate the accuracy of 3D helical CT and its value in surgical planning for the treatment of ureteropelvic junction obstruction (UPJO).

Method: CT scans and 3D reconstruction of renal vessels and the renal pelvis were performed in 20 cases of UPJO treated by open surgery. We analyzed scans in search of a vessel at the junction and its position relative to the UPJ.

[Cowper's gland: anatomic, physiological and pathological aspects].

Cowper's glands are small appendages of the male genital tract, that are sometimes observed on intravenous urography voiding films. They are involved in the immune defence of the genitourinary tract, play a role in fertility, and secrete many glycoproteins, including PSA. They can be visualized in the form of a duct image parallel to the urethra, sometimes associated with opacification of the gland on IVU.

[Feasibility of "Valsalva Leak Point Pressure". Prospective study].

Objective: To prospectively evaluate the feasibility of determination of the Valsalva Leak Point Pressure (VLPP).

Patients And Methods: From 1st January to 31st July 1996, 155 consecutive patients investigated for urinary incontinence with no pelvis static disorder performed Valsalva manoeuvres during cystomanometry in order to determine the VLPP. The examination was performed in the standing position at a filling volume of 200 cc with then without a vesical pressure transducer.
