Ureteral duplex

Unintentional Foley catheter placement into a ureter is an extremely rare and life-threatening complication that can be easily prevented by early diagnosis. A misplaced Foley catheter should be suspected in the presence of abdominal pain and oliguria after bladder catheterization, and congenital variation of the urinary tract can complicate this procedure. We reported the third case of misplaced insertion of a Foley catheter into the upper moiety ureter of a duplex kidney in a 19-year-old post-partum woman...

Background: Indocyanine green (ICG) is a fluorescent dye used for several indications in adult surgery, and, more recently, adopted also in the pediatric patients. This study aimed to review the literature published on the use of ICG near-infrared fluorescence (NIRF) in pediatric urology, to address its shortcomings and disadvantages and to detect the future perspectives. Materials and Methods: An electronic literature search of PubMed on all studies reporting use of ICG-NIRF in pediatrics was performed. We included only studies reporting ICG-NIRF application in minimally invasive surgery (MIS) for pediatric urology indications...

RATIONALE: Ureteral triplication (UT) is a very rare disorder, with a challenging diagnosis and varied therapeutic methods. In the past, the treatment usually involved heminephrureterectomy of the stunted moiety. Here, we reported a case of complete UT that was treated by laparoscopic triple-ureteral ureteroureterostomy (UU). PATIENT CONCERNS: A 2-year-old girl presented with frequent urine incontinence. Intravenous pyelography and voiding cystourethrography revealed a 3-segment left kidney with pelvi-ureteric dilation of the upper and middle moieties and grade IV to V vesicoureteral reflux...

INTRODUCTION: The best surgical approach to ectopic ureters and ureteroceles is yet to be determined. The objective of this study is to provide an alternative lower tract surgical approach to ectopic ureters and duplex system ureteroceles that can be safely performed in young children. METHODS: The "in-and-out" bladder approach was performed via an open intravesical incision. The upper and lower pole ureters were mobilized and brought into the bladder. The dilated ureter/ureterocele was cut open, and the distal part was deuroepithelialized...

BACKGROUND: Duplication of the renal pelvis is a common congenital malformation of the urinary system. About one-third of cases are complete unilateral duplication of the renal pelvis, while bilateral duplication is extremely rare. Herein, we described a single case of bilateral renal duplication with double ureteral orifice ectopic vaginal fistula treated with laparoscopy. CASE SUMMARY: A 6-year-old girl suffering from long-term vaginal leakage was admitted on June 10, 2018...

PURPOSE: To evaluate renal function damage in children with duplex kidneys. METHODS: A total of 355 duplex kidneys, 110 urinary tract infection (UTI) kidneys without abnormalities, and 104 kidneys with primary unilateral vesicoureteral reflux (VUR) were reviewed. Clinical data including age at diagnosis, body weight, history of UTI, ureteroceles, ectopic ureteral opening, VUR grade, serum creatinine level, cystatin C level, renal scarring, split renal function in dimercaptosuccinic acid scans, and effective renal plasma flow (ERPF) were analyzed...

Duplex collecting systems are common congenital abnormalities of the urinary tract but are infrequently reported in adult populations. This abnormality can present with hydroureteronephrosis secondary to urinary tract obstruction or concomitant vesicoureteral reflux (VUR), recurrent urinary tract infections (UTIs), and urinary incontinence. Options for surgical management include common-sheath ureteral reimplantation, uretero-ureterostomy, pyelostomy, and heminephroureterectomy. We report the case of a 39-year-old female with a duplex kidney who presented with severe hydroureteronephrosis following a sacrocolpopexy...

BACKGROUND: Ureteral injury and vaginal fistula are common complications after surgical treatment and radiotherapy of gynecological tumor1 , 2 . Ureteral injury in duplex system is more challenging and rarely reported3 . OBJECTIVES: We report our surgical techniques of totally intracorporeal robot-assisted bilateral ileal ureter in a patient who had a bilateral ureteral injury with duplex ureter. MATERIALS: We present a case of a 61-year-old female who suffered from flank pain and vaginal fistula due to ureteral injury after a radical hysterectomy and radiotherapy for cervical cancer...

Ectopic ureters are rare congenital malformations of the urinary tract, more frequent in females and most commonly associated with single collecting system in males. We report a case of a prostate cancer patient undergoing robotically assisted laparoscopic radical prostatectomy. Duplication of vas deferens was thought to be found during surgery. Postoperatively, patient developed fevers. CT showed incidental finding of duplex collecting system on the left with dilatation of the upper moiety. Percutaneous nephrostomy was placed but an attempt at antegrade insertion of ureteric stent was unsuccessful...

INTRODUCTION: Duplex renal collecting systems are one of the most common congenital anomalies of the urinary tract. The exact prevalence of this anomaly is difficult to ascertain because most patients are asymptomatic, and the abnormality is frequently detected incidentally. The aim of this study is to retrospectively review the demographic characteristics and different clinical presentations, related pathology, and treatment methods of patients with duplex system anomaly who applied to our institution, with a literature review...

Giant hydronephrosis is an ultimate rare urologic entity; even rarer when it is secondary to a duplex collecting system. Duplex collecting system is a common urologic anomaly with a wide range of clinical symptoms and a variety of associated urologic abnormalities such as an ectopic ureter, ureterocele, vesicoureteral reflux and ureteropelvic junction obstruction. This report presents a case of an 8-year-old boy who had a bilateral duplex collecting system that was revealed accidentally by a bilateral severe hydronephrosis...

Ureteral duplication is a common embryologic abnormality of the kidney with an incidence rate of 0.8% in adults. However, complete duplex ureters opening independently into the urinary bladder are rarely present. We report a 35-year-old female who presented with left flank pain in the last three years. Abdominal CT scan showed left complete duplicated system with lower moiety hydroureteronephrosis and obstructed midureteral stone. The patient underwent left retroperitoneal exploration with complete excision of the hydronephrotic sac...

Introduction: Megaureter, described as ureter dilatation more than 7 mm in diameter, commonly associated with other anomalies, is still a diagnostic and therapeutic challenge. Magnetic resonance urography (MRU) appears as a promising method in urinary tract imaging, providing both anatomical and functional information. There are several postprocessing tools to assess renal function (including differential renal function) and severity of ureteral obstruction based on MRU. Still, the place of this method in the diagnostic algorithm of ureteropelvicalyceal dilatation with megaureter remains underestimated...

INTRODUCTION: Duplex collecting system is a common congenital urinary system anomaly and is usually asymptomatic. Vascular variations associated with a duplex system are common but haven't been reported as obstructive. CASE REPORT: 14-month-old female had a right sided incomplete ureteral duplication complicated by lower pole hydroureteronephrosis due to distal ureteral obstruction by an aberrant vessel crossing the bifid ureters at ureteric junction of these bifid ureters...

INTRODUCTION: The management of UCs remain controversial, especially for UCs with duplex collecting systems that still represent a great challenge in paediatric urology. Several approaches have been used and a shared management is not yet validated. STUDY AIM: Aim of our study is to evaluate the results of the endoscopic treatment of UC comparing ortothopic single-system UC and ectopic duplex-system UC over a 10-year period in a single referral tertiary center. Success was defined as resolution of dilation, lack of urinary infections and preservation of renal function...

We present the first case of a right ectopic ureter ending in epididymis combined with an ipsilateral complete duplex kidney, presenting with painless right scrotal mass and demonstrated by magnetic resonance imaging (MRI). The boy was initially diagnosed as right testicular teratoma by ultrasound, and then underwent surgical treatment. Because of recurrence of right scrotal swelling 1 year later, MR scan was performed. MR images with body coil displayed the entire ectopic ureter, and MR images with small surface coil clearly showed anatomic details of right ureteral ectopia into epididymis...

Congenital anomalies of the kidney and urinary tract (CAKUT) are a family of often-concurrent diseases with various anatomical spectra. Null-mutant Gen1 mice frequently develop multiple urinary phenotypes, most commonly duplex kidneys, and are ideal subjects for research on ectopic budding in CAKUT development. The upper and lower kidney poles of the Gen1PB/PB mouse were examined by histology, immunofluorescence, and immunohistochemistry. The newborn Gen1PB/PB mouse lower poles were significantly more hypoplastic than the corresponding upper poles, with significantly fewer glomeruli...

Ureteric injuries from blunt trauma are rare in adults requiring prompt diagnosis and management. To our knowledge this is the second case report of a complete transection of the ureter due to blunt injury at the pelvi-ureteric junction in an adult. Following a high-speed road traffic collision, a 26-year-old female with bilateral duplex kidneys was admitted with complete transection of the lower moiety of her right collecting system confirmed on computed tomography Urogram. This was repaired successfully with a minimally invasive laparoscopic technique in keeping with European Association of Urology guidelines...

PURPOSE: Retrospective comparative study of the efficacy of extravesical non-dismembered common sheath ureteral reimplantation (ECSR) versus intravesical common sheath ureteral reimplantation (ICSR) techniques for the correction of vesicoureteral reflux (VUR) in complete duplex systems. MATERIAL AND METHODS: Between 2010 and 2019, ECSR was performed in 38 children (8 bilaterally), and the mean ages at presentation and at surgery were 31 and 57 months, respectively...
