During the last decade, annual volume of robot-assisted prostatectomies performed in United States has risen steadily. Refinements surgical technique, understanding anatomy, and experience have led to more complex patients being offered surgery for management organ-confined prostate cancer. Complication rates prostatectomy been reported several articles; however, a paucity data exists when evaluating ureteral injuries sustained during prostatectomy. No standardized universal criteria...
Ureteroneocystostomy is the standard mode of establishing urinary drainage in renal transplantation. However, donor-to-recipient ureteroureterostomy may be considered presence a challenging bladder or an augmented bladder, when donor ureter might compromised too short. This approach also preserves nonrefluxing system with orthotopic ureteral orifice.We retrospectively reviewed records all pediatric transplantations which was performed at single tertiary care center over 12-year period from...
Radiological imaging is the mainstay of diagnosing ureteropelvic junction obstruction. Current established radiological modalities can potentially differentiate varying degrees obstruction but they are limited in functionality, applicability and/or comprehensiveness. Of particular concern that some tests require radiation, which has long-term consequences, especially children.We investigated novel use Genhance™ 680 dynamic fluorescence to assess 20 mice underwent partial or complete...
Host-pathogen interactions can induce epigenetic changes in the host directly, as well indirectly through secreted factors. Previously, uropathogenic Escherichia coli (UPEC) was shown to increase DNA methyltransferase activity and expression, which associated with methylation-dependent alterations urothelial expression of CDKN2A. Here, we showed that paracrine factors from infected cells alter another writer, EZH2, coordinate proliferation. Urothelial were inoculated UPEC, UPEC derivatives,...
Approximately 50,000 children undergo voiding cystourethrography annually. There is a recent trend toward using sedation or delaying due to the anticipated distress patient. We hypothesized that with adequate preparation and proper techniques minimize anxiety, can be performed without sedation. assessed parental satisfaction associated patient parent experience of sedation.We used 33-question survey evaluate Children were divided into 3 groups according toilet training status.

In children with congenital obstructive uropathy, including posterior urethral valves, lower urinary tract decompression is recommended pending definitive surgical intervention. Current options, which are limited to a feeding tube or Foley catheter, pose unappreciated constraints in luminal diameter and associated potential problems. We assess the impact of on current draining options present novel alternative method, repurposing widely available stent that optimizes drainage.We...
OBJECTIVES: Elective newborn circumcision, one of the most common surgical procedures in world, is often performed with either Gomco clamp or Mogen clamp. Our aims were to determine differential circumcision revision and complication rates due technique differences outcomes when residents versus attending physicians procedure. METHODS: We conducted a retrospective chart review newborns who underwent elective at our children’s hospital from January 2013 June 2017 using Current Procedural...
In laparoscopic prostatectomies, vesicourethral anastomotic leaks may result in significant morbidity because of the chemical and metabolic derangements created by urine within peritoneal cavity. To date, minimal data are available on this problem. Herein we present our experience with after RALP. Over a period 24 months, 135 men underwent Any drainage creatinine greater than two times serum was considered as an leak. According to criteria, 20% first 110 patients developed The were analyzed...
Abstract Intra‐operative arterial vasospasm during pediatric renal transplantation is an urgent clinical situation resulting in end‐organ ischemia, associated changes parenchymal turgor and color, diminished flow on ultrasound, if left untreated, allograft loss. We hypothesized that intra‐operative intra‐arterial injection of nitroglycerin would reverse improve perfusion. A three‐yr‐old girl with end‐stage disease due to autosomal recessive polycystic kidney peritoneal dialysis underwent...
Vesicoureteral reflux is believed to be a largely asymptomatic condition. However, previous studies have failed assess the precise impact of vesicoureteral on quality life. We created and validated survey for assessment life in children with reflux.Two surveys were by team pediatric urologists design specialists, 1 general postoperative patients undergoing surgical treatment reflux. Cronbach alpha test was used internal consistency reliability correlation coefficient test-retest analysis....
The management of vesicoureteral reflux is a mainstay pediatric urology. This however, has evolved considerably throughout the years due to dynamic understanding both pathology and relationship between surgical medical therapies. purpose this article provide reader with historical perspective on delineate how its past shaped current therapies guidelines.
Many surgical disciplines, particularly those specializing in the pediatric age group, use microsurgical instruments with assistance of either optical loupe or microscope magnification to perform high precision procedures. We developed a course consisting two parts: Part 1 consists low fidelity, inanimate exercises training and practice platform, part 2 employed rat model. In this report, we describe provide templates for first course, namely platform as an integral set six low-fidelity...
