PURPOSE: Despite the increasing use of advanced 3D imaging techniques and 3D printing, these techniques have not yet been comprehensively compared in a surgical setting. The purpose of this study is to explore the effectiveness of five different advanced imaging modalities during a complex renal surgical procedure. METHODS: A patient with a horseshoe kidney and multiple large, symptomatic stones that had failed Extracorporeal Shock Wave Lithotripsy (ESWL) and ureteroscopy treatment was used for this evaluation...

Horseshoe kidney (HSK) is a congenital defect of the urinary tract that occurs in 0.25% of the general population. Laparoscopic Vascular Hitch (LVH) according to Hellstrom-Chapman represent an alternative approach in treatment of extrinsic hydronephrosis by crossing vessels (CV) in pediatric age. In our Department from 2006 to 2016, 36 children with extrinsic-Uretero-Pelvic-Junction (UPJ)-Obstruction (UPJO) underwent laparoscopic vessels transposition. Over the last 4years, we have treated three patients with extrinsic hydronephrosis in HSK; two males and one female respectively of 6, 7 and 8years...

Primary neuroendocrine carcinoma of the kidney is a rarely observed clinical condition because neuroendocrine cells are not found in kidney parenchyma. It's not clinically and radiologically possible to distinguish from other kidney tumors. Incidence with horseshoe kidney anomaly, it should be considered as a definitive diagnosis for the patients with this condition. In this case report, we reported about a carcinoid tumor in horseshoe kidney in a 37-year-old woman.

Introduction: The horseshoe kidney (HSK) is the most common type of renal fusion anomaly. The incidence and characteristics of kidney stones in patients with HSK are not well studied. The aim of this meta-analysis was to evaluate the incidence and types of kidney stones in patients with HSK. Methods: A systematic literature search was performed using MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews from the databases' inception through November 2016...

OBJECTIVE: to assess the feasibility and outcomes of laparoscopic pyeloplasty in children with complex ureteropelvic junction obstruction (UPJO) and compare to children with iso-lated UPJO without associated urinary tract abnormalities. MATERIAL AND METHODS: Medical records of 82 consecutive children submitted to transperitoneal laparoscopic pyeloplasty in a 12-year period were reviewed. Eleven cases were con-sidered complex, consisting of atypical anatomy including horseshoe kidneys in 6 patients, pelvic kidneys in 3 patients, and a duplex collecting system in 2 patients...

OBJECTIVE: To examine the risk for clinically significant chromosomal microarray analysis (CMA) among fetuses with apparently isolated horseshoe kidney. METHODS: Data from all CMA analyses performed due to isolated horseshoe kidney reported to the Israeli Ministry of Health between January 2013 and September 2016 were retrospectively obtained from a computerized database. Risk estimation was performed comparing the rate of abnormal CMA findings to the general population, based on a systematic review encompassing 9272 pregnancies with normal ultrasound, and local data cohort of 5541 pregnancies undergoing CMA due to maternal request...

Context: Survival rates exceed 90% in Wilms' tumor (WT). Actinomycin-D (ACT-D) which is indispensable in the management of WT is associated with the development of sinusoidal obstruction syndrome (SOS), a potentially fatal complication. Aims: The aim is to study the presentation, management, and outcome of SOS complicating ACT-D administration in WT. Settings and Design: Retrospective file review conducted in a Pediatric Hematology-Oncology unit...

OBJECTIVE: To review the literature and present a case of robotic-assisted laparoscopic partial nephrectomies in horseshoe kidney. METHODS: We describe a case of a right side oncocytoma in a horseshoe kidney managed robotically and review the literature of robotic-assisted laparoscopic surgical resection of kidney tumors in renal fusion anomalies. RESULTS: There are only 3 published cases of robotic-assisted laparoscopic partial nephrectomy (RAPN) for renal tumours in a horseshoe kidney in the literature...

Estimation formulas are usually used to calculate renal depth when glomerular filtration rate (GFR) is measured by the Gates method. Horseshoe kidney (HSK) anatomical structure is different from the normal form of the kidney. The existing formulas are based on the normal form. It is unknown whether the existing formulas are valid in HSK patients. This study was performed to estimate the accuracy of the existing 6 renal depth estimation formulas in HSK.Renal depth and total thickness (T, cm) of the body at the level of the kidneys were measured by CT in 94 HSK patients...

The horseshoe kidney (HSK) is common and supernumerary kidney is the rarest developmental anomaly of the urogenital system. The supernumerary kidney in a HSK conjunction is extremely rare, and prevalence of it is unknown. A review of literature, there have been a few case reports about the supernumerary and HSK combination, however, none of which also had a concomitant kidney stone and obstructive pathology. Our case indicated that patient referred to flank pain and visible hematuria to our clinic, and further investigations demonstrate supernumerary kidney in a horseshoe configuration and kidney stone...

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: Renal injuries occur in 10% of blunt abdominal traumas, 7% of these occur in kidneys with congenital or acquired disorders. Trauma of horseshoe kidney is an uncommon finding. PRESENTATION OF A CASE: We present the case of 31 year-old caucasian man with no remarkable personal records, who was brought to our Trauma Unit soon after being involved in a motorcycle collision. A Contrast Enhanced - Multi Detector Computed Tomography (ce-MDCT) revealed a double disconnection of a horseshoe kidney...

Abdominal aortic aneurysm (AAA) with associated horseshoe kidney (HSK) poses a technical challenge when performing conventional open surgical repair because of possible complications including renal infarction, neuralgia, and collecting system disruption. Endovascular aortic repair (EVAR) is considered the first-line treatment for this pathology, allowing for aneurysm repair without isthmus bisection. However, whether to sacrifice commonly presenting aberrant renal arteries during EVAR is a point of controversy...

OBJECTIVE: To analyze the results of flexible ureterorenoscopy (F-URS) with holmium laser in the treatment of kidney stones with ectopic and fusion anomalies (horseshoe kidney and rotation anomalies). METHOD: We reviewed data from 13 patients with fusion and ectopic renal anomalies that underwent F-URS from April 2011 to April 2017. We analyzed demographic and clinical data (age, gender, BMI, anatomical abnormality, location and dimension of the renal calculi) and perioperative data (method of treatment, stone-free rate, number of days with DJ catheter and perioperative complications)...

AIM: To determine the place of laparoscopic pyelolithotomy in surgical management of nephrolithiasis. MATERIALS AND METHODS: We analyzed 16 laparoscopic pyelolithotomies performed in our clinic over the last few years for large and stag-horn stones of anomalous kidneys (n=8), the "giant" (>30-40 cc) monolithic stones of the large extrarenal pelvis (n=3), multiple stones of PCS with the stone burden of more or equal 40 cm (n=2) and large recurrent (after PCNL) kidney stones in patients at risk of bacteriotoxic complications of percutaneous nephroscopy (n=3)...

Down syndrome (DS) is often associated with cardiac malformations, so that kidney damage is little known. The objective of this study was to present the diversity of renal abnormalities and their potential progression to chronic renal failure. Among congenital abnormalities of the kidney and urinary tract (CAKUT) abnormalities appear to be frequent: pyelectasis, megaureters, posterior urethra valves, as well as renal malformations such as renal hypoplasia, horseshoe kidney, or renal ectopia. Contributing factors to acute kidney failure have been described in patients with DS: bilateral lesions and minor renal injury, such as glomerular microcysts, tubular dilation, and immature glomeruli...
