A 71-year-old male presented with a complaint of right abdominal pain. An extravasation of urine was noted, and was improved by indwelling urethral catheterization.(More)
INTRODUCTION Laparoendoscopic single-site surgery is a recently innovated urologic surgical procedure. Transumbilical laparoendoscopic single-site adrenalectomy (LESS-A) is technically safe and feasible in patients with benign adrenal tumors. To improve patient counseling and informed consent, we evaluated patient-reported postoperative pain, body image,(More)
A 26-year-old woman presented to our hospital with right costovertebral angle (CVA) pain. Ultrasonographyand computed tomography(CT) scan indicated right hydronephrosis, and MAG3 renogram showed an obstructed pattern in the right kidney. Enhanced CT scan revealed an ureteropelvic junction obstruction (UPJO) with an aberrant vessel. To clarifythe(More)
We performed Pfannenstiel laparoendoscopic reduced-port bilateral radical nephrectomy on a patient with renal cell carcinoma undergoing hemodialysis. A 4-cm Pfannenstiel incision was made, and a GelPOINT access was inserted. Three trocars were placed through the access platform, and additional 5- and 3-mm trocars were inserted in the umbilicus and(More)
Recently, numerous studies have reported an association between sarcopenia and poor outcomes in various kinds of malignancies.
