INTRODUCTION: We present a robot-assisted approach to surgical treatment of UPJ obstruction associated with crossed renal ectopia in a male infant. METHODS: A 31 year-old woman presented at 37 weeks gestation for prenatal hydronephrosis and delivered at 39 weeks. Renal ultrasound identified the bladder and right kidney in a crossed ectopic position in the left pelvis, and MRI showed the cystic lesion to be hydronephrosis associated with a ureteropelvic junction obstruction of the crossed ectopic right kidney...

Introduction: Laparoscopic approach in horseshoe kidney (HSK) is a challenge because of the aberrant vessels, the renal isthmus and the renal ectopia are all unique features of this anomaly encountered during the surgery. We report our single center experience with this technique in managing three patients with HSK. Methods: A total of 15 cases (9 males and 6 females) were operated between June 2011 and December 2016 for various indications. Of these four patients were managed laparoscopically, two patients with HSK had non-functioning renal moiety underwent transperitoneal heminephrectomy...

INTRODUCTION: Dismembered pyeloplasty remains the gold standard for the treatment of pelviureteric junction obstruction (PUJO). Robotic approach to this procedure has proven its efficacy and is gaining popularity. The introduction of barbed sutures such as "V-Loc™" (Covidien) has provided an addition to the sutures available for pyeloplasty. This work provides our experience with the V-Loc suture for closure of pelvis in children for robotic pyeloplasty (RP). MATERIALS AND METHODS: A review of 10 pediatric RP (da Vinci Robotic System) during which the V-Loc suture was used was performed...

INTRODUCTION: Ureteropelvic junction obstruction (UPJO) is the most common cause of hydronephrosis in children. One major challenge in the management of UPJO is to select the patients that must be subjected to early obstruction relief. Currently, there is no gold standard for this assessment. Therefore, the aim of the present study was to evaluate the urinary levels of carbohydrate antigen (CA) 19-9 and normalized CA 19-9 (Ca 19-9/Cr ratio) in UPJO patients before and after surgery and compare them with a control group to assess their potential clinical application as an assisting tool in diagnosis of UPJO patients...

Ureteropelvic junction obstruction (UPJO) causes a reduction in the urine flow from the renal pelvis into the ureter. Untreated UPJO may cause hydronephrosis, chronic infection or urolithiasis and will often result in progressive deterioration of renal function. Most cases of UPJO are congenital; however, the disease can be clinically silent until adulthood. Other causes, both intrinsic and extrinsic, are acquired and include urolithiasis, post-operative/inflammatory/ischemic stricture, fibroepithelial polyps, adhesions and malignancy...

Ureteropelvic stenosis, also known as ureteropelvic junction obstruction, is an obstruction in the region of the pyeloureteral junction resulting in a urinary discharge disorder of the renal pelvis, which requires treatment.Since the first description of pyeloplasty by Trendelenburg in 1886 and the successful establishment of open pyeloplasty by Anderson and Hynes in 1949, the treatment strategies for ureteropelvic junction obstruction have developed considerably, especially in the last two decades. Although open pyeloplasty is still considered to be the gold standard, this concept is supplemented by modern minimally-invasive techniques today...

Port placement for robot-assisted laparoscopic urologic surgery can be critical to effective completion of the minimally invasive procedure. An ideal port template would allow unhampered access to all critical structures during surgery, easy access for the bedside assistant, and minimization of arm collision with the fewest ports necessary to minimize cosmetic impact. We present a comprehensive plan for the placement of ports across different procedures for a variety of upper tract (radical/partial nephrectomy, retroperitoneal radical/partial nephrectomy, and pyeloplasty), lower tract (prostatectomy, and cystectomy), combined upper/lower tract (nephroureterectomy, retroperitoneal lymph node dissection), and female pelvic surgeries...

OBJECTIVE: To examine the effectiveness of the 3 primary treatments for ureteropelvic junction obstruction (ie, open pyeloplasty, minimally invasive pyeloplasty, and endopyelotomy) as assessed by failure rates. MATERIALS AND METHODS: Using MarketScan data, we identified adults (ages 18-64 years) who underwent treatment for ureteropelvic junction obstruction between 2002 and 2010. Our primary outcome was failure (ie, need for a secondary procedure). We fit a Cox proportional hazards model to examine the effects of different patient, regional, and provider characteristics on treatment failure...

INTRODUCTION: Congenital pelviureteric junction obstruction (PUJO) is one of the most frequent causes of neonatal hydronephrosis. Obstruction at the PUJ has potential severe adverse outcomes, such as renal damage. While pyeloplasty has been established as the definitive treatment, the exact pathophysiology of congenital PUJO remains unknown. Recent research has proposed neuronal innervation defects as an etiological factor in congenital PUJO. We aim to study the expression of various neuronal markers in PUJO specimens compared with controls, and evaluate whether severity of renal disease or dysfunction pre-operatively is related to expression of neuronal markers in resected PUJO specimens...

Paediatric urological surgery is often required for managing congenital and acquired disorders of the genitourinary system. In this Series paper, we highlight advances in the surgical management of six paediatric urological disorders. The management of vesicoureteral reflux is evolving, with advocacy ranging from a less interventional assessment and antimicrobial prophylaxis to surgery including endoscopic injection of a bulking agent and minimally invasive ureteric reimplantation. Evidence supports early orchidopexy to improve fertility and reduce malignancy in boys with undescended testes...

CONTEXT: The key in the evolution towards minimally invasive surgery is the availability of appropriate equipment, especially when procedures involve children. While robotic procedures in adults continue to struggle to prove measurable advantages compared with open or classical laparoscopic ones, the use of the robotic platform (RP) in pediatric urology is steadily increasing. OBJECTIVE: To review the contemporary literature regarding the use of robotic-assisted (RA) urologic interventions in children...

OBJECTIVE: Giant hydronephrosis (GH) is a rare entity in both developed and developing countries with less than 500 cases reported in the literature. Delayed diagnosis and management of GH, can result in long-term complications like hypertension, rupture of the kidney, renal failure and malignant change. We aim to highlight the importance of this often neglected entity and build a consensus for its early diagnosis and management. MATERIAL AND METHODS: Patients with GH were thoroughly worked up, managed and followed up between June 2013 and December 2015 and epidemiologic, radiological, perioperative and follow-up data was recorded...
