Validation of a Novel, Sensitive, and Specific Urine-Based Test for Recurrence Surveillance of Patients With Non-Muscle-Invasive Bladder Cancer in a Comprehensive Multicenter Study.

Bladder cancer (BC), the most frequent malignancy of the urinary system, is ranked the sixth most prevalent cancer worldwide. Of all newly diagnosed patients with BC, 70-75% will present disease confined to the mucosa or submucosa, the non-muscle-invasive BC (NMIBC) subtype. Of those, approximately 70% will recur after transurethral resection (TUR).

Collecting duct carcinoma of the kidney. A contribution of 4 new cases.

Objective: Collecting duct carcinoma of the kidney is a rare and aggressive subtype of renal cell carcinoma with low cancer-specific survival. We reviewed our series of collecting duct tumours retrospectively.

Methods/results: We performed a retrospective analysis of the collecting duct carcinomas of the kidney treated in our unit between January 2007 and December 2012.

Laparoscopic dissection of the intramural ureter to repair a complete transection of the distal ureter: Initial experience with a new minimally invasive technique that preserves the anatomy of the urinary tract.

We report 2 patients with ureteral injury after a simple total laparoscopic hysterectomy for uterine myoma with a complete resection of the distal ureter. One patient had unilateral injury and the other 2 patients had bilateral injury. The surgical laparoscopic repair procedure was carried out 3 to 5 days after the injury.

Lithiasis size estimation variability depending on image technical methodology.

Unlabelled: The lithiasic size is a determining factor in selecting the most suitable treatment, surgical or medical. However, the method for obtaining a reliable lithiasic size is not standardized. Our objetives are to determine the differences between the estimated lithiasic sizes shown by plain radiography test and by computerized axial tomography (CT) scan (using different techniques) in relation to the actual size, and to establish which is the ideal type of imaging for this purpose.
