Comparing Periurethral Injection of Autologous Muscle-Derived Stem Cell and Fibroblasts with Mid-Urethral Sling Surgery in the Treatment of Female Stress Urinary Incontinence: A Randomized Clinical Trial.

Objective: In this study, we analyzed the therapeutic effect of periurethral injection of autologous muscle-derived stem cell versus mid-urethral sling surgery at a 1-year follow-up.

Method: This randomized controlled clinical trial was conducted on 30 women with stress urinary incontinence (SUI) who had not responded to conservative treatments, after registering the participants and obtaining informed consent. Patients were divided into two groups of 15 each treated with periurethral injection of muscle-derived stem cells (MDSCs) and mid-urethral sling surgery, respectively.

Percutaneous nerve evaluation (PNE) for treatment of non-obstructive urinary retention: urodynamic changes, placebo effects, and response rates.

Purpose: To evaluate the results of percutaneous nerve evaluation (PNE) implantation in the treatment of non-obstructive urinary retention and report the changes in the urodynamic parameters.

Materials And Methods: Patients with non-obstructive urinary retention or incomplete bladder emptying were included. All patients filled a 7 days voiding diary chart and underwent PNE for one week, and the patient was asked to record the second voiding diary chart and repeat urodynamic study in this period.

An assessment of serum sodium within 48 h after percutaneous nephrolithotomy with half-strength saline solution.

The aim of this study was to evaluate the postoperative serum sodium changes after percutaneous nephrolithotomy (PCNL) with half-strength saline irrigation.

Transperitoneal laparoscopic partial nephrectomy using a new technique.

Introduction: We report our experience with a new technique for transperitoneal laparoscopic partial nephrectomy with the kidney turned upside down intraoperatively.

Materials And Methods: Laparoscopic partial nephrectomy was performed in 10 patients with upper pole lesions through a transperitoneal approach. Once complete mobilization of the kidney was achieved, it was rotated 180 degrees around the horizontal axis, so that the upper pole was positioned inferiorly.

Pre-transplant and post-transplant soluble CD30 for prediction and diagnosis of acute kidney allograft rejection.

Background: Serum levels of soluble CD30 (sCD30) have been considered as a predictor of acute kidney allograft rejection. We have evaluated the pre-transplant and post-transplant levels of sCD30 with the aim of determining its value in predicting and diagnosing kidney rejection.

Methods: We measured sCD30 serum levels before kidney transplantation, 5 days post-operatively, and at creatinine elevation episodes.

Tension-free vaginal tape and autologous rectus fascia pubovaginal sling for the treatment of urinary stress incontinence: a medium-term follow-up.

Objectives: To compare two different procedures, tension-free vaginal tape (TVT) and autologous rectus fascia sling, according to their medium-term subjective and objective outcomes and satisfaction rates in the treatment of urinary stress incontinence in women.

Subjects And Methods: One hundred women with type II urinary stress incontinence were randomized to be treated with either TVT or autologous rectus fascia sling. They were evaluated by means of a cough-induced stress test, 1-hour pad test, Incontinence Impact Questionnaire (IIQ), and urodynamic study.

Hepatitis C in hemodialysis patients: current global magnitude, natural history, diagnostic difficulties, and preventive measures.

Hepatitis C virus (HCV) infection is a significant cause of morbidity and mortality in hemodialysis (HD) patients. The reported prevalence of HCV among the HD population has varied greatly from 1.9 to 84.

Laparoscopic management of varicocele using bipolar cautery versus open high ligation technique: a randomized, clinical trial.

Purpose: The aim of this investigation was to compare laparoscopic management of varicocele using bipolar cautery with open high ligation technique.

Materials And Methods: A total of 100 patients were operated on for left-sided varicoceles. To evaluate the clinical efficiency of the treatment, the patients were divided randomly into two groups.

Bowel preparation versus no preparation before ileal urinary diversion.

Objectives: To compare the outcome and complications of urinary diversion using ileum, with and without bowel preparation. Recent studies have questioned the necessity of bowel preparation, especially for urinary diversion when ileum is used.

Methods: In this clinical trial, 30 candidates for urinary diversion underwent a 3-day standard bowel preparation (group 1), and 32 were admitted 24 hours before surgery and received only a soft diet, with no oral intake, 8 hours before surgery (group 2).

Is preemptive kidney transplantation preferred? Updated study.

Introduction: For eligible patients with end-stage renal disease, the dialysis stage could be bypassed by preemptive kidney transplantation (PKT), when the organ is available. We compared this treatment option with kidney transplantation in patients with pretransplant dialysis (PTD).

Materials And Methods: We retrospectively studied on 300 patients who received PKT between 1992 and 2006 from living donors.

A comparison between laparoscopic and open pyeloplasty in patients with ureteropelvic junction obstruction.

Introduction: Our aim was to compare clinical and radiological outcomes, complications, and hospital stay in laparoscopic and open pyeloplasty.

Materials And Methods: From February 2002 to February 2003, 69 patients with ureteropelvic junction obstruction (UPJO) were assigned into two groups. Thirty-seven patients underwent transperitoneal laparoscopic pyeloplasty and 32 underwent open surgical pyeloplasty.

Transcutaneous ultrasound guided nephrolithotomy: the first report from Iran.

Purpose: To evaluate the safety and efficacy of transcutaneous ultrasound guided nephrolithotomy.

Materials And Methods: From December 1999 to December 2000, 12 patients with renal stone were selected for PCNL. Six patients had failed ESWL and the remainder had multiple and large stones in pelvis and lower calyx.

Human amniotic membrane as a suitable matrix for growth of mouse urothelial cells in comparison with human peritoneal and omentum membranes.

Introduction: For tissue engineering of the urinary tract system, cell culture requires to be established in vitro and an appropriate matrix acting as cell carrier should be developed. The aim of the present study was to assess the proliferation quality of mouse urothelial cells on 3 natural matrixes of human amniotic membrane (AM), peritoneum, and omentum, and to compare them with collagen matrix.

Gil-Vernet antireflux surgery in treatment of lower pole reflux.

Purpose: Prevalence of ureter and kidney duplication is roughly 1 per 125 people, and is associated with vesicoureteral reflux to lower pole in about 45% of cases. From antireflux surgical principles viewpoint, standard antireflux surgeries can be performed in these kidneys without releasing ureters from each other. We studied the results of Gil-Vernet antireflux surgery in 12 patients with duplicated collecting system and lower pole reflux.
