Relevance of Imaging Examinations in the Surgical Planning of Patients with Bowel Endometriosis.

Endometriosis is a benign gynecologic disease characterized by the presence of endometrial tissue outside the uterine cavity. The complexity of the disease results from its multiple clinical presentations, the multifocal pattern of distribution of the lesions, the presence of extra pelvic sites of the disease (mainly affecting the urinary and the intestinal tracts), and the difficulty in the preoperative diagnosis (by means of imaging studies) and in the surgical treatment. The preoperative mapping of the lesions, either by ultrasound or by magnetic resonance imaging, allows for an adequate surgical planning and a better preoperative patient counseling, especially in those women with deep infiltrating endometriosis affecting the bowel.

Nephrectomy as a cause of chronic kidney disease in the treatment of urolithiasis: a case-control study.

Objective: To analyze the clinical course of nephrectomized patients due to complications related to nephrolithiasis and ascertain the prevalence of chronic kidney disease (CKD) in this population.

Methods: From 2005 to 2010, 658 patients were treated with urolithiasis. Among these, 30 (4.

Characterization and clinical evaluation of a novel IMRT quality assurance system.

Intensity-modulated radiation therapy (IMRT) is a complex procedure that involves the delivery of complex intensity patterns from various gantry angles. Due to the complexity of the treatment plans, the standard-of-care is to perform measurement based patient-specific quality assurance (QA). IMRT QA is traditionally done with film for relative dose in a plane and an ion chamber for absolute dose.
