BACKGROUND The role of lateral retroperitoneoscopic adrenalectomy (LRA) for complicated tumor with large diameter remains controversial, this study aimed to evaluate the effectiveness of this procedure on the management of tumor larger than 5cm in diameter. METHODS A retrospective comparison was conducted of 67 patients with large complicated adrenal tumor (>5cm). 41 patients received LRA, an...

BACKGROUND Chyluria is a rare disease in Japan. Lymphatic disconnection is the most effective treatment for patients with Chyluria, and laparoscopic approach is performed as a minimally invasive technique. CASE PRESENTATION We present a case of a 40-year-old man who referred to our hospital because of recurrence of chyluria. Chyluria had continued for 20 years, and the patient had received re...

Background . Renal cell carcinoma is one of the most common urologic cancers. Due to development modern diagnostic methods, kidney tumors are often diagnosed at early stages (cT1a-T1b). The golden standard treatment localized renal tumor resection. In retroperitoneoscopic access, time artery access decreased, risk intra- and postoperative complications reduced. Retroperitoneal preferable for lo...

Introduction: Adrenal cysts are rare findings, with an age peak between the third and fifth decades of life. In adults, laparoscopic and retroperitoneoscopic approaches to these cysts have been described. In pediatric patients, however, reports of this pathology and its management are limited to a small number of case reports. Case Report: A cystic mass was discovered in the left upper abdomina...

The effect of glucocorticoids on pro-opiomelanocortin (POMC) gene transcription in the rat pituitary has been investigated by an in vitro nuclear runoff transcription assay. Both dexamethasone and corticosterone had rapid inhibitory effects on POMC transcription in the anterior lobe but not in the intermediate lobe of the pituitary. These effects were maximal during the first hour after injecti...

OBJECTIVE To evaluate the presentation, management, pathology, and functional and oncological outcomes of patients undergoing retroperitoneoscopic treatment of bilateral synchronous sporadic RCC at our institution. METHODS We retrospectively evaluated the records of 60 patients with bilateral synchronous sporadic RCC who underwent retroperitoneoscopic treatment at the General Hospital of Peop...

Immunocytochemical studies have shown that adrenalectomy produces changes in the content and distribution of [arginine-8]vasopressin (AVP) immunoreactivity in the paraventricular nucleus of the hypothalamus. The purpose of this study was to determine whether manipulation of adrenal hormones affects the levels of AVP mRNA. In situ hybridization assays with highly specific synthetic oligodeoxyrib...

BACKGROUND AND OBJECTIVES To compare laparoscopic transperitoneal versus retroperitoneoscopic pyeloplasty for primary ureteropelvic junction obstruction in a prospective randomized manner and assess overall results with long-term follow-up. METHODS In this prospective study, from 2008 to 2012, 112 cases of primary ureteropelvic junction obstruction were randomized in a 1:1 ratio into 2 groups...
