Laparoscopic Versus Open Partial Nephrectomy for Stage T1a of Renal Tumors.

Purpose: Partial nephrectomy is the gold standard treatment for small kidney masses. Data on the comparison oflaparoscopic (LPN) versus open partial nephrectomy (OPN) are based on retrospective studies. Thus, we plannedto compare these two techniques in a prospective trial.

Stent Removal in 200 Kidney Transplant Recipients: Nonoperative Versus Endoscopic Removal.

Objectives: Inserting a double J stent during kidney transplant has reduced the rate of urologic complications. Traditionally, a double J stent is removed via endoscopic intervention. Here, we assessed the safety and efficacy of a nonoperative method for double J stent removal.

The histologic features of intratubular germ cell neoplasia and its correlation with tumor behavior.

Purpose: To assess the prevalence of intratubular germ cell neoplasia (ITGCN) in patients with concurrent testis tumor and its correlation with histologic features and serum tumor markers.

Materials And Methods: From 2003 to 2015, 179 patients underwent radical orchiectomy due to testicular mass. Tissue specimens were evaluated by an expert uro-pathologist using immunohistochemistry (IHC) staining, in addition to light microscopy, to identify presence of ITGCN.

Comparison of safety and efficacy of laparoscopic pyelolithotomy versus percutaneous nephrolithotomy in patients with renal pelvic stones: a randomized clinical trial.

Purpose: A randomized clinical trial was designed to compare the efficacy, success rate and surgical complications of percutaneous nephrolithotomy (PCNL) and laparoscopic pyelolithotomy (LP).

Materials And Methods: Sixty patients with renal pelvic stones larger than 2 cm were randomly divided into two groups of LP and PCNL. All patients were followed up to three months after surgery using renal diethylenetriamine­pentaaceticacid (DTPA) scan and determining the glomerular filtration rate (GFR).

Intermittent perirenal instillation of bupivacaine after tubeless percutaneous nephrolithotomy under spinal anesthesia: a double-blind, placebo-controlled clinical trial.

Background And Purpose: Pain at the surgery site is a common complaint in patients who experience percutaneous nephrolithotomy (PCNL). The aim of this double-blind, randomized clinical trial is evaluation of the effect of scheduled infusion of bupivacaine on postsurgical pain and narcotic consumption after tubeless PCNL under spinal anesthesia.

Patients And Methods: Forty patients were randomly divided into two groups.
