[Active surveillance for prostate cancer: usefulness of endorectal MR at 1.5 Tesla with pelvic phased array coil in detecting significant tumors]. / Cancer de la prostate localisé: l'IRM endorectale à 1,5 Tesla améliore-t-elle la sélection des patients en vue d'une surveillance active?

PURPOSE: To describe and assess MRI signs of significant tumor in a series of patients who all underwent radical prostatectomy and also fulfilled criteria to choose active surveillance according to French "SurAcaP" protocol. PATIENTS AND METHODS: The clinical reports of 681 consecutive patients operated on for prostate cancer between 2002 and 2007 were reviewed retrospectively. All patients had endorectal MR (1.5 Tesla) with pelvic phased array coil. (1.5 T erMR PPA). Sixty-one patients (8.9%) fulfilled "SurAcaP" protocol criteria. Preoperative data (MR+core biopsy) were assessed by comparison to whole-mount step section pathology. RESULTS: 85.3% of the 61 patients entering SurAcaP protocol had significant tumor at pathology. (Non Organ Confined Disease (Non OCD)=8.2%, Gleason sum score>6=39.2%). A new exclusion criterion has been assessed: T3MRI±NPS>1 as a predictor tool of significant tumor. ("T3MRI±NPS>1"=Non OCD at MR±number of positive sextants involved in tumor at MR and/or Core Biopsy > to 1). Sensitivity, specificity, PPV, NPV of the criterion "T3MRI±NPS>1" in predicting significant tumor were, respectively: 77%, 33%, 86%, 20%. Adding this criterion to other criteria of the "SurAcaP" protocol could allow the exclusion of all Non OCD, and a decrease in Gleason sum Score>6 rates (20%). CONCLUSION: Endorectal MR at 1.5 Tesla with pelvic-phased array coil should be considered when selecting patients for active surveillance in the management of prostate cancer. A criterion based upon MR and core biopsy findings, called "T3MR±NSP>1" may represent an exclusion citeria due to its ability to predict significant tumor.

[Retroperitoneal laparoscopic treatment of symptomatic caliceal diverticular calculi]. / Traitement par laparoscopie rétropéritonéale d'un amas lithiasique intradiverticulaire caliciel symptomatique.

Treatment of urinary calculi in caliceal diverticular is indicated when they are symptomatic. Minimally invasive techniques, in particularly laparoscopic approach, occupy an increasingly important place in the urological therapeutic armamentarium and have changed from an open surgical approach to endoscopic treatment for the management of symptomatic caliceal diverticular calculi. Herein, we report the case of a woman with symptomatic calculi in an upper caliceal diverticular managed by retroperitoneal laparoscopic approach.

[Salvage cryotherapy for recurrent prostate cancer after radiotherapy failure: principles, indications, patient selection, oncological results and morbidity]. / Cryothérapie de rattrapage après radiothérapie prostatique : principes, indications, sélection des patients, résultats oncologiques et morbidité

Potentially curative salvage options for biochemical failure after primary prostatic radiotherapy include salvage radical prostatectomy, brachytherapy, high-intensity focused ultrasound and cryotherapy. Salvage cryoablation for recurrent prostate cancer after irradiation failure is currently a well-established therapeutic option, since technical improvements have permitted better oncologic outcomes and lower complications rates over the years. This article reviews surgical technique, oncologic and functional outcomes, as well as morbidity and complications of salvage cryotherapy for local recurrence after external beam radiotherapy or brachytherapy for prostate cancer.
