Objective- Laparoscopic partial nephrectomy (LPN) has been proven to be a safe and effective technique in human. This study was conducted to evaluate the feasibility and safety of utilizing laparoscopic partial nephrectomy in dogs and to compare this technique with open routine partial nephrectomy for the first time in Iran. Design- Experimental study. Animals- Sixteen large mixed-breed femal...

BACKGROUND Renal cell carcinoma (RCC) is a common malignancy of the urinary system with high rates of morbidity and mortality. OBJECTIVES This study aimed to investigate and analyze the clinical efficacy of retroperitoneal laparoscopic partial nephrectomy and laparoscopic radical nephrectomy for the treatment of small RCC. METHODS In this retrospective study of 45 patients with small RCC, t...

1. In the dog and monkey bilateral nephrectomy or ureteral ligation results in a marked, progressive increase of total fatty acids, of free and esterified cholesterol, of phospholipid, and of free fat of serum. 2. No such changes follow unilateral nephrectomy, splenectomy, or fasting. 3. The increase after bilateral nephrectomy is not inhibited by glucose administration. 4. A marked increase of...

BACKGROUND The increase of intraabdominal pressure to 10 mmHg provokes a decrease of renal blood flow (RBF). Pneumoperitoneum during laparoscopic techniques with intra-abdominal pressure (IAP) to 15 mmHg, results in a decrease in RBF, urine output and glomerular filtration rate (GFR). PURPOSE Analyze the changes in RBF, urine output an GFR in a porcine experimental model during open vs laparo...

Thyroid gland metastatic tumors are rare in clinical practice. Clear cell RCC is one of common metastatic tumors to thyroid. We here reported a case of incidentally found clear cell renal carcinoma metastasis to the thyroid gland 3 years after nephrectomy, in the thyroidectomy procedure performed for the patient due to the thyroid enlargement caused by multinodular goiter. A 65-year-old Iranian...

Importance Use of robotic surgery has increased in urological practice over the last decade. However, the use, outcomes, and costs of robotic nephrectomy are unknown. Objectives To examine the trend in use of robotic-assisted operations for radical nephrectomy in the United States and to compare the perioperative outcomes and costs with laparoscopic radical nephrectomy. Design, Setting, and...

PURPOSE Open partial nephrectomy has emerged as the standard of care in the management of renal tumors smaller than 4 cm. While laparoscopic radical nephrectomy has been shown to be comparable to open radical nephrectomy with respect to long-term outcomes, important questions remain unanswered regarding the oncological efficacy of laparoscopic partial nephrectomy. We examined the practice patte...

Data regarding the outcomes of peritoneal dialysis (PD) patients undergoing nephrectomy are limited. In the 20-year retrospective study reported here, we included patients who underwent nephrectomy and then subsequently started PD within 1 year (group A) and those who underwent nephrectomy while already on PD (group B). We examined mechanical complications including incisional hernia, peritonea...

AIM Mechanisms that initiate compensatory renal growth following unilateral nephrectomy are incompletely understood. An early event following unilateral nephrectomy is the activation of phospholipase C in the apical membrane of the proximal tubule, mediated by an unknown agonist. We tested the hypothesis that endothelin is responsible for the stimulation of phospholipase C in rat proximal tubul...

OBJECTIVE To evaluate the surgical outcomes and morbidity of retroperitoneoscopic nephrectomy compared with open nephrectomy for dialysis dependent patients. MATERIAL AND METHOD Between November 2002 and August 2007, 14 hemo or peritoneal dialysis patients underwent nephrectomy or nephroureterectomy at Siriraj Hospital. Of the 14 patients, seven were treated with retroperitoneoscopic nephrect...
