Robot-Assisted Laparoscopic Management of Caliceal Diverticular Calculi.

Standard treatment modalities of caliceal diverticular calculi range from extracorporal shockwave lithotripsy (SWL) over retrograde intrarenal surgery (RIRS), percutaneous nephrolithotomy (PNL) and laparoscopic stone removal. A 55-year-old woman presented with a history of pyelonephritis based on a caliceal diverticular calculus. Due to the narrow infundibulum and anterior location, a robot-assisted laparoscopic calicotomy with extraction of the calculi and fulguration of the diverticulum was performed, with no specific perioperative problems and good stone-free results.

Dynamic contrast enhanced, pelvic phased array magnetic resonance imaging of localized prostate cancer for predicting tumor volume: correlation with radical prostatectomy findings.

Purpose: We assessed the value of pelvic phased array dynamic contrast enhanced magnetic resonance imaging for predicting the intraprostatic location and volume of clinically localized prostate cancers.

Materials And Methods: Suspicious areas on prospective pre-biopsy magnetic resonance imaging in 24 patients were assigned a magnetic resonance imaging malignancy score and located with respect to anatomical features, gland side, and transition and peripheral zone boundaries. The largest surface area and volume were measured.

[Biopsy technique and biopsy schemes for a first series of prostatic biopsies].

Objective: To define the modalities of prostatic biopsies in patients with suspected prostate cancer, particularly concerning prevention of complications, the number of biopsies and the biopsy schemes ensuring an optimal cancer detection rate, and recording of prognostic elements, all with an acceptable morbidity,

Method: Review of the literature.

Results: Information before biopsy: A preliminary visit with oral and written information is necessary before any biopsy procedure in order to: describe the modalities of the procedure to improve the patient's cooperation, detect contraindications, guide preparation, explain the risks and elements of surveillance, and describe the management in the case of complications (level of evidence: IV-3). PREPARATION BEFORE BIOPSY: A single dose of prophylactic antibiotic is necessary before the examination.

[Should scrotal ultrasound be discouraged in cases of suspected spermatic cord torsion?].

Objective: To assess the value of scrotal ultrasound to guide the diagnosis of torsion of the spermatic cord.

Material And Methods: Retrospective study from January 1995 to June 2001. One hundred and sixty eight patients were admitted to the emergency department with an empirical diagnosis of torsion of the spermatic cord.
