Importance of precise imaging for stone identification during shockwave lithotripsy: a critical evaluation of "OptiVision" as a post-processing radiography imaging modality.

To evaluate the efficacy of a unique imaging software "OptiVision" on the confidence of stone identification using X-ray imaging during shockwave lithotripsy. A total of 57 patients with solitary radio-opaque kidney stones sized < 15 mm were included and evaluated with appropriate radiological imaging and laboratory studies before undergoing shockwave lithotripsy (SWL). The size of the stones was measured on KUB and CT images using maximal stone diameters.

Hand-assisted Laparoscopic Left Donor Nephrectomy Without a Hand-assisted Device: Is it Possible?

Background: Live donor nephrectomy is an important donor source. Donor nephrectomy can be performed by laparoscopy or hand-assisted laparoscopy. Different types of hand port devices can be used for assistance.

Comparison of subdermal and perforator delay techniques on a rat flap model.

Background: In this study, we investigated the subdermal and perforator delay phenomena as a method to improve flap survival.

Materials And Methods: In this experimental study, we used 24 rats in three groups. In the control group, the dorsal flaps were elevated and reinserted back to their place.

Review of Novel Sentinel Lymph Node Biopsy Techniques in Breast Cancer Patients Treated With Neoadjuvant Chemotherapy.

Breast cancer patients who present with nodal metastasis receive neoadjuvant chemotherapy (NAC) with increasing frequency and can have complete pathologic response after treatment. In this clinical scenario, sentinel node mapping and biopsy are gaining acceptance instead of axillary dissection to avoid morbidity. Biopsy proven positive lymph nodes must be reliably excised and examined after NAC to further decrease the false negativity rate of sentinel lymph node (SLN) surgery.

A rare cause of chest pain mimicking myocardial infarction.

We present a patient who underwent endoscopic retrograde cholangiopancreatography procedure for bile duct stone removal and sphincterotomy. Upon completion of the procedure, the patient experienced severe chest pain. Because myocardial infarction was the likely diagnosis, we immediately performed a coronary angiography, which identified severe coronary lesions without any total occlusion.

Furosemide infusion prevents the requirement of renal replacement therapy after cardiac surgery.

Objective: Acute kidney injury (AKI) is a devastating complication following cardiac surgery and the ideal management is controversial. This prospective, randomized, open-label and double-blinded study analyzed the renoprotective effects of furosemide infusion and intermittent bolus therapy administered with dopamine infusion in cardiac surgical patients.

Methods: Between August 1, 2007 and July 31, 2008, 100 adult patients undergoing elective coronary artery bypass surgery (CABG) surgery with normal renal function (creatinine <1.
