Purpose: The percutaneous nephrolithotomy (PCNL) has become the gold-standard for treating patients with the larger renal stones and staghorn calculi. This study was designed to evaluate the outcomes of flank versus prone position in patients underwent ultrasonic-guided PCNL for treatment of large kidney stones.
Methods: This prospective randomized clinical trial was conducted from September 2017 to September 2019 in the department of Urology, Labbafinejad University hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran.
Purpose: To evaluate the intraoperative pain score of patients who undergo percutaneous nephrolithotomy under spinal anesthesia and to evaluate surgeons' and patients' convenience with this type of anesthesia.
Materials And Methods: PCNL cases who were performed by two endourology fellows under spinal anesthesia during June to July 2014 were included. Spinal anesthesia was performed using injection of 0.
Purpose: To present our experience with synchronous or metachronous laparoscopic pyelolithotomy and ureterolithotomy for patients with bilateral urolithiasis.
Materials And Methods: The data of all patients who underwent laparoscopic pyelolithotomy (± ureterolithotomy) for bilateral renal and/or ureteral stones from November 2009 to July 2014 were included. Laparoscopic operations were performed through a transperitoneal approach.
Background: Percutaneous nephrolitotomy (PCNL) is the preferred treatment for large renal stones. There is a need for more comparative data for different lithotripters used in PCNL.
Objective: To evaluate the comparative safety and efficacy of ultrasonic and pneumatic lithotripsy in patients undergoing PCNL.
Objectives: To evaluate the success of ultrasonography directed renal access in entering the target calyx from proper entry site and in the direction of renal pelvis during percutaneous nephrolithotomy (PCNL).
Materials And Methods: PCNL cases who were operated on by one fellow from May-June 2014 were included in this study. A vertically placed ultrasound probe on the patient flank in prone position was used to identify the preselected target calyx.
Background: Using percutaneous nephrolitotomy (PCNL) with large adult instruments in treatment of pediatricurolithiasis is still in debate. This study was conducted to evaluate the efficacy and safety of PCNL with adult's instrument in treatment of patients less than 3 years old.
Methods: Data on patient characteristics and outcomes for 261 consecutive children undergoing PCNL at a Labbafinejad University Hospital were collected prospectively from September 2006 to February 2016.
Purpose: Our goal was to present our experience with ultrasound guided supine or prone percutaneous nephrolithotomy in three pregnant women under spinal anesthesia.
Materials And Methods: Three pregnant women in the 16th, 20th and 28th weeks of pregnancy presented with symptomatic large renal stone in the first patient and multiple renal stones in the second and third patients which were unresponsive to conventional medical therapy. They requested a definitive stone treatment.
Background And Objectives: Major vascular injury is the most devastating complication of laparoscopy, occurring most commonly during the laparoscopic entry phase. Our goal is to report our experience with major vascular injury during laparoscopic entry with closed- and open-access techniques in urologic procedures.
Methods: All 5347 patients who underwent laparoscopic urologic procedures from 1996 to 2011 at our hospital were included in the study.
Purpose: To compare human urothelial and smooth muscle cells attachment and proliferation using three different matrices; poly lactic-co-glycolic acid (PLGA), PLGA/collagen and human amniotic membrane (hAM).
Materials And Methods: Human urothelial and smooth muscle cells were cultured and examined for expression of urothelium (pancytokeratin and uroplakin III) and smooth muscle cells [desmin and alpha smooth muscle actin (α-SMA)] markers. Cells were cultured on three scaffolds; PLGA, PLGA/collagen and hAM.
Background: Bladder cancer is a relatively common and potentially life-threatening neoplasm that ranks ninth in terms of worldwide cancer incidence. The aim of this study was to determine deletions and sequence variations in the mitochondrial displacement loop (D-loop) region from the blood specimens and tumoral tissues of patients with bladder cancer, compared to adjacent non-tumoral tissues.
Methods: The DNA from blood, tumoral tissues and adjacent non-tumoral tissues of twenty-six patients with bladder cancer and DNA from blood of 504 healthy controls from different ethnicities were investigated to determine sequence variation in the mitochondrial D-loop region using multiplex polymerase chain reaction (PCR), DNA sequencing and southern blotting analysis.
Purpose: To evaluate the efficacy of autologous single-donor fibrin glue after tubeless percutaneous nephrolithotomy (PCNL).
Materials And Methods: Forty-three patients were planned for tubeless PCNL in a prospective cohort study and randomized in two groups with or without using fibrin glue. Randomization method was based on the computer-generated random numbers.
Laparoscopic anatrophic nephrolithotomy for management of staghorn renal calculi.

Background: Management of staghorn renal stones is still challenging. We present our experience with laparoscopic anatrophic nephrolithotomy as an alternative option for management of staghorn renal calculi.
Patients And Methods: Twenty-four patients with staghorn renal calculi underwent 25 laparoscopic anatrophic nephrolithtomy procedures.
Purpose: To evaluate the safety and cost-effectiveness of Hem-o-lok and metallic titanium clips for both renal arterial and venous control in laparoscopic nephrectomies.
Patients And Methods: All patients who underwent laparoscopic nephrectomy from June 2000 to March 2011 in our center were included. Before July 2005, we used three medium-large titanium clips for safe control of renal vessels.
Background: Recent developments in laparoscopic and retroperitoneoscopic techniques have modified the treatment of renal and ureteral stones. We present the efficacy and possible adverse complications of laparoscopic pyelolithotomy for the treatment of staghorn stones as an alternative to percutaneous nephrolithotomy (PCNL) in our single-surgeon series.
Patients And Methods: Thirteen patients (10 males and 3 females) underwent transperitoneal laparoscopic pyelolithotomy for removal of staghorn stones.
Purpose: To compare the outcome of corporeal plication using absorbable versus nonabsorbable sutures for the treatment of congenital penile curvature.
Materials And Methods: Thirty-eight men older than 15 years old with congenital penile curvature were enrolled in the study. Patients were randomly divided into two equal groups based on the suture material (Nylon versus Vicryl) used in corporeal plication.
Introduction: We report a new modified technique of unaltered appendix transfer to ileal pouch and preserving ileocecal segment. This modification enables us to use ileum as the popular type of enteric segment instead of ileocecal segment while using appendix as a catheterizable stoma.
Materials And Methods: Forty-five patients (30 men) who needed reconstruction of the lower urinary tract were enrolled for using appendix as a catheterizable stoma.
Background: There are contradictory reports on the relationship between acne vulgaris and cigarette smoking. The objective of this study was to examine the relation between acne and cigarette smoking in a case-control study.
Methods: A questionnaire on smoking habits was offered to 350 patients with acne vulgaris and 350 patients suffering from skin diseases other than acne, aged 15-40 years, attending in a skin clinic in Tehran, Iran.
