OBJECTIVES: To assess the role of TEO/TEM in recto-urethral fistulas (RUF). RUF may appear after radical prostatectomy. Their treatment represents a challenge; many therapies have been proposed, from conservative to aggressive surgical approaches. Transanal endoscopic surgery (TEO/TEM) is a minimally invasive technique to access the site of the RUF to perform repair. METHODS: Observational study with prospective data collection, conducted between September 2006 and December 2015...

The present study aimed to systematically evaluate the effectiveness and safety of the intrafascial and interfascial nerve sparing (ITR-NS and ITE-NS) radical prostatectomy. PubMed, Embase, and Cochrane Library databases were searched for eligible studies. Meta-analysis with random-effects model was performed. Six comparative trials were selected and embraced in this research, including one randomized controlled trial, three prospective comparative trials, and two retrospective comparative trials. With regard to perioperative parameters, no significant association of operative time, blood loss, transfusion rates, duration of catheterization, and hospital stay existed between ITR-NS and ITE-NS...

BACKGROUND: Identifying the epidural space is essential during epidural anesthesia (EA). Pressure of the epidural space in pregnancy is higher than that in nonpregnant woman. Loss of resistance (LOR) method is the most commonly preferred method for identifying the epidural space. Epidrum and Epi-Jet are recently innovated supporting devices that facilitate identifying process for epidural space. In this study we aimed to compare Epidrum, Epi-Jet, and LOR methods in identifying the epidural space, feasibility of technique...

OBJECTIVES: To report the results of a novel surgical technique for achieving urinary continence in patients with bladder exstrophy complex (BEC) by ureteric-urethral engraftment (UUE) technique. PATIENTS AND METHODS: Sixteen female patients with BEC and a mean ± SD age of 3.48 ± 1.75 years were referred for primary exstrophy repair from 2009 to 2012. From these, 9 patients were operated by single-stage bladder closure (group I); while 7 patients underwent the novel technique of UUE to compare the continence achievement (group II)...

The relative pressure difference across stenotic blood vessels serves as an important clinical index for the diagnosis of many cardiovascular diseases. While the clinical gold standard for relative pressure difference measurements is invasive catheterization, Phase-Contrast Magnetic Resonance Imaging has emerged as a promising tool for enabling a non-invasive quantification, by linking highly spatially resolved velocity measurements with relative pressures via the incompressible Navier-Stokes equations. In this work we provide a review and analysis of current methods for relative pressure estimation and propose three additional techniques...

OBJECTIVE: An adjustable Ghajar guide is presented to improve the accuracy of the original Ghajar guide technique. The accuracy of the adjustable Ghajar guide technique is also investigated. METHODS: The coronal adjustment angle from the orthogonal catheter trajectory at Kocher's point is determined based on coronal head images using an electronic picture archiving and communication system. For the adjustable Ghajar guide, a protractor is mounted on a C-shaped basal plate that is placed in contact with the margin of a burrhole, keeping the central 0° line of the protractor orthogonal to the calvarial surface...

The inspection of the liver is a valuable part of the upper endoscopic ultrasonography (EUS) studies, regardless of the primary indication for the examination. The detailed images of the liver segments provided by EUS allows the use of this technique in the study of parenchymal liver disease and even in the diagnosis and classification of focal liver lesions. EUS has also emerged as an important tool in understanding the complex collateral circulation in patients with portal hypertension and their clinical and prognostic value...

Objectives To reduce the incidence of Urinary Tract Infection (UTI) in subacute SCI individuals admitted for tertiary inpatient rehabilitation. Design A quality improvement team was assembled to improve UTI prevention/diagnosis. To plan data collection, UTI-related factors were mapped in an Ishikawa (fishbone) driver diagram. Data including patient demographics, presence and frequency of signs and/or symptoms of UTI and antibiotic initiation from August to December 2015 were recorded. Sensitivity, Specificity, Positive and Negative Predictive Values (PPV, NPV), and Likelihood Ratios (LR) were calculated for each sign and symptom...

Orthotopic heart transplantation is a well-established and effective therapeutic option for children with end-stage heart failure. Multiple modalities, including noninvasive cardiac imaging, cardiac catheterization, angiography, and endomyocardial biopsy, are helpful to monitor these patients for graft dysfunction, rejection, and vasculopathy. Because of morbidities associated with invasive monitoring, noninvasive imaging plays a key role in the surveillance and evaluation of symptoms in pediatric transplant recipients...

PURPOSE: To compare long-term results of three different techniques used to create continent catheterizable channels (CCCs) in children in a single institution. PATIENTS AND METHODS: Data were retrospectively collected from 112 children who had a CCC [appendicovesicostomy (APV), tubularized bladder flap (TBF) or Monti] created between December 1995 and December 2013. Primary outcome was revision-free survival. Secondary outcomes were channel stenosis, incontinence, and false channel requiring revision...

OBJECTIVE: For in vitro tissue engineering in urology, stem cells are commonly isolated from tissue specimens obtained during open or endoscopic surgery. Within the context of the present study our aim was to isolate cells from human urine by an alternative and safe technique rather than using the indicated method.

Postpartum hemorrhage causes 25% of all maternal deaths worldwide and is the leading cause of maternal morbidity and mortality following vaginal or caesarean delivery. Every year, postpartum hemorrhage is estimated to cause approximately 125 000 maternal deaths and is associated with morbidity among 20 million women. It is caused by several obstetric conditions, including uterine atony and placental problems such as placenta accreta spectrum disorders, trauma, and lacerations. Several techniques are known to prevent postpartum hemorrhage, including uterine cavity tamponade, uterine artery ligation, uterine artery embolization, pre-cesarean prophylactic balloon catheterization, uterine compression sutures, hypogastric artery ligation, and hysterectomy...

The transurethral resection of bladder tumor (TURBT) remains the most widely used method in the surgical treatment of the non-muscle invasive bladder tumor (NMIBT). Despite its popularity, the laser technique has been widely used in urology as an alternative, via the application of transurethral laser enucleation of bladder tumor. The aim of the present study was to compare the efficacy and feasibility between transurethral laser enucleation and transurethral resection of bladder tumor. A systematic search of the following databases was conducted: PubMed, Wed of Science, Cochrane Library, EMBASE, Google scholar, and Medline...

Transradial coronary angiography has been known as an alternative to the transfemoral approach with fewer serious complications. Radial artery pseudoaneurysms present as a rare complication of transradial catheterization. Although some methods have been applied for the obliteration of pseudoaneurysms, the use of radial bands such as the TR Band(®) (Terumo Medical Corporation, Somerset, NJ) is a novel efficient technique only suggested by a few reports. We describe a 34-year-old man, who underwent transradial primary coronary angiography due to ST-elevation myocardial infarction...

In this article, we present a case of recurrent laryngeal nerve palsy not caused by nerve injury but due to local anesthetic infiltration that was applied prior to central venous catheterization. A 47-year-old female patient was admitted to emergency room with fatigue and nausea and was diagnosed with acute renal failure. Right jugular venous catheterization was performed for emergency hemodialysis with Seldinger technique using middle approach. Within minutes and immediately after the procedure the patient complained of hoarseness and shortness of breath, and she had stridor in her physical exam...
