Abstract Background: Closure of large patent ductus arteriosus (PDA) in older children has been accomplished using surgical and percutaneous techniques with remarkable outcomes. However, outcomes amongst infants have been variable with several drawbacks. Here we describe a novel minimally invasive technique, a product of mini-thoracotomy and traditional percutaneous technique skills, accomplished exclusively under echocardiography guidance. Methods: Symptomatic infants with a significant left-to-right shunt from PDA measuring more than 4 mm were selected. The symptoms were varying degrees of tachypnea, tachycardia, heart failure, failure to thrive, recurrent respiratory tract infections, or intensive care unit treatment for a longer duration.… More >

Abstract Introduction: To evaluate the impact of an “opt-in” non-narcotic postoperative pain regimen on narcotic utilization and patient-reported pain scores.
Materials and methods: A prospective, non-blinded pre- and post-interventional trial was conducted, including a lead-in period for baseline evaluation. The intervention group received a new pain protocol prioritizing non-narcotic medications, an “opt-in” requirement for opiates, and standardized patient education. Study outcomes included opiate prescription and utilization (measured in Morphine Equivalent Doses) and reported pain scores on postoperative day (POD) 1, discharge, and follow-up.
Results: At discharge, 70% fewer patients were prescribed any opioids (ARR: -0.7; p < 0.001); the… More >

Abstract Background: In an effort to reduce postoperative trauma and achieve more cosmetic results, minimally invasive approaches to correct congenital heart anomalies have been recently proposed and increasingly adopted. Here we describe our experience for the past 23 years. Methods: Patients who underwent a surgical procedure between February 1996 and March 2019 with a minimally invasive approach for the correction of congenital heart disease in our center were included in this study. A statistical analysis was carried out to compare the results of the different minimally invasive techniques. A meta-analysis was conducted to compare our results in… More >

Abstract Introduction: Minimally invasive nephroureterectomy (MINU) and open nephroureterectomy (ONU) have similar oncological outcomes for treatment of upper tract urothelial carcinoma (UTUC). We investigated perioperative outcomes and predictors of complications associated with MINU and ONU.
Material and methods: Using the National Surgical Quality Improvement Program (NSQIP) database, 912 patients were identified that underwent radical nephroureterectomy for UTUC between 2005 and 2013. Logistic regression and contingency table methods used preoperative covariates to predict rates of major (Clavien-Dindo grade ≥ 3) and 16 common perioperative complications. Additional comparisons between treatment groups were performed using unpaired t-tests, Wilcoxon rank-sum tests, or… More >

Abstract Introduction: Placement of anterior abdominal wall trocars during laparoscopic radical prostatectomy (LRP) carries the risk of inadvertent injury to the inferior epigastric artery (IEA) and potential conflict between midline and lateral ports. We described and evaluated a new measured port placement approach.
Materials and methods: The intervention group included patients who underwent LRP using a specifically measured five-port approach. The medial 10 mm ports were placed 5 cm from the patient’s midline at a level midway between the anterior superior iliac spine (ASIS) and the umbilicus. The control group had five ports placed at the surgeon’s discretion.… More >

Abstract Introduction: Surgical glove integrity is important in preventing wound infections and reducing patient mortality. Rates of perforations have been studied in many surgical subspecialties, but glove perforations specific to urology have not been investigated previously. This study aims to determine the incidence of glove perforations during urological surgeries and to investigate differences between open, laparoscopic, and endoscopic procedures.
Materials and methods: A total of 180 gloves were collected from various urological procedures performed at our institution: 59 from endoscopic, 72 from laparoscopic, and 49 from open cases. The gloves were tested for defects by both the water… More >

Abstract Introduction: To evaluate preoperative parameters of patients undergoing partial nephrectomy to determine variables that impact selection of operative approach.
Materials and methods: The charts of 229 consecutive patients undergoing partial nephrectomy were reviewed. Clinical data points and associated axial imaging were evaluated to determine factors which contributed to selection of an open (versus laparoscopic) operation.
Results: A total of 140 men and 89 women with a mean age of 57 years, body mass index (BMI) of 31, and glomerular filtration rate (GFR) of 82 mL/min/1.73 m² were included. Twenty-three percent of patients had prior abdominal surgery and 7% had… More >

Abstract Umbilical laparoendoscopic single-site surgery (U-LESS) is a relatively new technique for minimally invasive surgery being implemented in patients with urological complaints. We report the case of an incontinent 8-year-old girl who successfully underwent U-LESS for nephrectomy of a minimally functioning kidney with ectopic ureteral insertion into the vagina. More >

Abstract Natural orifi ce transluminal endoscopic surgery (NOTES) has attracted considerable recent attention for its potential to allow traditional abdominal procedures to be performed without a transabdominal incision. With considerable experience in the development and application of minimally invasive techniques, urologists have played a signifi cant role in early experimental NOTES efforts and have contributed to early investigations in human subjects accordingly. However, adoption of these techniques has been limited due to cumbersome endoscopic equipment and concerns regarding peritonitis from failed viscerotomy closure. Experience with use of NOTES in human subjects is limited, and studies comparing More >
