Ureteral Triplication Research Articles

Nefrectomia unilateral videolaparoscópica devido triplicação ureteral incompleta: Relato de caso pediátrico

Ureteral triplication is due to the abnormal development of the ureteral bud, which begins in the 4th week of gestation. The ureteral bud, originating from the mesonephric duct, comes into contact with the nephrogenic blastema, and then the metanephric mesenchyme induces the ureteral bud to divide. Interference in this branching process can result in some anomalies, such as duplication or triplication of the ureter. Ureteral triplication is a very rare congenital disease. It is slightly more common in females and is usually associated with other congenital anomalies.

Triplicate Ureter with Complicated Ureteral Cyst in an Ectopic Malrotated Kidney: A Rare Association

One of the rarest anomalies of the renal collecting system is ureteral triplication along with the presence of a complex ureteral cyst. We describe an unusual case of a 37-year-old man who presented with fever and abdominal pain. Computed tomography urography (CTU) revealed triplication of the ureter in association with renal ectopia and a ureteral cyst which was complicated by calculi formation. Following treatment with antibiotics, the patient was managed by open ureterolithotomy with resection of the ureteral cyst and tailoring of the ureter.

Management of Vesicoureteral Reflux in a Patient With Recurrent Febrile Urinary Tract Infections, Neurogenic Bladder, and Ureteral Triplication

Ureteral triplication is a rare anomaly with about 100 total cases reported in the literature. In this case presentation, we present a case of ureteral triplication in a young female with a history of neurogenic bladder secondary to L5 lipomeningocele who presented with recurrent febrile urinary tract infections (UTIs) and vesicoureteral reflux despite antibiotic prophylaxis. Given her high grade reflux, she underwent ureteral reimplantation which ultimately led to resolution of her UTIs and reflux. Later in her clinical course, toilet training unmasked additional bladder dysfunction and she was successfully managed with clean intermittent catheterization and anticholinergics. To the best of our knowledge, this is the first case report to describe ureteral triplication, recurrent febrile UTIs and vesicoureteral reflux in the setting of a concomitant neurogenic bladder with a successful outcome.

Rare cases of ectopic ureter: Analysis from a single centre with review of the literature.

Purpose of our study was to aggregate and analyse rare cases of Ectopic Ureter (EU), their association with other anomalies, clinical features, diagnosis and management. A total of nine patients with rare presentation of EU were evaluated. Combination of endoscopic and imaging modalities was used as required to define the anatomy and devise the best surgical approach in these cases. Among six females and three males with EU, four cases had bilateral EU, four unilateral EU and one case had EU of a solitary kidney. Urinary incontinence was encountered in five cases including one male patient whilst other cases presented with varied clinical features and associated anomalies. Two patients had anorectal malformations, and two had uterine anomalies in the form of bicornuate uterus. Other patients had multiple rare associations such as triplication of ureter, bilateral absence of seminal vesicles with infertility, multicystic dysplastic kidney, ureter draining in uterus, renal failure, absence of bladder trigone, and hypospadias etc. Ureteric reimplantation was performed in four cases, two required ureteroureterostomy, another two had undergone upper pole nephrectomy and in one case renal transplant had been carried out owing to chronic renal failure. EU is among group of those congenital entities which remain shrouded until adulthood, when symptoms become distressing. Fortunately, prognosis is favourable after surgical correction, in spite of its rarity. Complexity arises when other associated anomalies are identified.

Ureteral Triplication Associated With Upper Pole Ureteropelvic Junction Stenosis

Triplication of ureter (TU) is a rare but important disease occurring in children. TU occurs with the early division of the ureteric bud or with three buds arising from mesonephric duct. It is commonly associated with other urological anomalies such as contralateral ureteric duplication, ureteral ectopia and renal dysplasia. Our case is a 3-year-old girl who presented with right triplex ureters and ureteropelvic junction (UPJ) obstruction of the upper pole. Diagnostic tools used in our case study were ultrasound (US), retrograde pyelography and CT urography for imaging. CT urography is a useful diagnostic tool for pediatric patients because it gives more information about anatomical details. J Med Cases. 2018;9(7):195-197 doi: https://doi.org/10.14740/jmc3060w

Unilateral Ureteral Triplication (Type 2) With Contralateral Trifid Pelvis

Ureteral triplication is one of the rarest malformations of the upper urinary tract. We report a case of ureteral triplication associated with hematuria. Computed Tomography (CT) Urography was performed and right ureteral triplication with contralateral trifid pelvis was diagnosed.

Intraureteral and intravenous indocyanine green to facilitate robotic partial nephroureterectomy in a patient with complete ureteral triplication

A patient with a complete right ureteral triplication presented with recurrent pyelonephritis and flank pain that was refractory to medical management. Evaluation showed that the atrophic upper-most renal moiety had been chronically obstructed and was associated with a dilated ureter. Intraureteral and intravenous indocyanine green (ICG) were used as real-time contrast agents intraoperatively to facilitate right robotic partial nephroureterectomy of the diseased system. Intraureteral ICG was used to accurately distinguish the pathologic ureter and associated renal pelvis from its normal counterparts. Intravenous ICG was used to assess perfusion in the right kidney and delineate the margins of diseased renal parenchyma.

Ureteroureterostomy irrespective of ureteral size or upper pole function: A single center experience

ObjectiveAlthough ureteroureterostomy (UU) is an established procedure for the treatment of duplex anomalies, there may be a reluctance to apply this approach to patients with poor upper pole function and/or marked degrees of ureteral dilation. MethodsAn institutional review board (IRB)-approved retrospective analysis of all patients undergoing UU between 2006 and present was performed. All patients underwent an end-to-side anastomosis with a double-J stent left in the lower pole ureter. Laparoscopic repairs were done ‘high’ and open repairs were done ‘low’. If the upper pole ureter remained massively dilated after transection, the ureter was partially closed to reduce the length of the anastomosis. Data collected included demographics, diagnosis, surgical interventions, imaging studies and outcomes. ResultsA total of 41 patients (43 renal units) were identified. There were 35 females and six males with an average age at surgery of 2.3 years (range 55 days to 15.9 years) and an average follow up of 2.8 years. Diagnosis included ureterocele (17), ectopic duplex ureter (25) and ureteral triplication (1). Thirty-six patients underwent UU only and five underwent UU with simultaneous lower pole reimplantation. Twelve of the 41 patients (29%) underwent laparoscopic repair. Twelve of the 43 renal units (28%) required ureteral tapering, of which three were performed laparoscopically. Preoperative median upper pole function was 17% (0–35%).Six patients had no measurable function and ten had < 15%. No patient developed lower pole hydronephrosis in the follow-up period. There were two complications: one patient was found to have a post-operative ureterovesical junction (UVJ) stricture and the second had an anastomotic stricture. ConclusionUreteroureterostomy is a safe and effective technique for the reconstruction of duplex anomalies, even with a massively dilated and poorly functioning upper pole moiety. With no identifiable negative effect on the lower pole system, the concept of automatically removing ‘dysplastic’ upper pole segments can be challenged.

Ureteral Quintuplication With Renal Atrophy in an Infant After the 1986 Chernobyl Nuclear Disaster

Ureteral duplication is a comparatively frequent urinary tract anomaly. Ureteral triplication is rare, but quadruplication is extremely rare. In this study, we describe a case of ureteral quintuplication, the first such report in the English-language literature. A newborn female baby was diagnosed with left ureteral quintuplication. The left ureter was divided into 5 ureters with 5 renal pelvises within approximately 3cm of the urinary bladder, and trace parenchyma of the kidney was noted. The patient was born within 60km of the epicenter of the 1986 Chernobyl disaster, 24years after the catastrophic nuclear accident, and is currently aged 3years.

Ureteral triplication

Ureteral triplication is one of the rare anomalies of the urinary system. The following case describes management of child with triple system of right kidney with refluxing upper moiety ureter. It is not unusual to find such clinical presentations but the embryology with relevance to these malformations has been intriguing. The recent knowledge of the molecular mechanisms governing the process of ureteral budding and elongation raises some important questions. The current report discusses and hypothesizes the concept that certain family of molecules may be responsible for helping the ureteral bud to find its way to the respective metanephros.

Ureteral triplication: A rare anomaly with a variety of presentations

Ureteral triplication remains a very rare congenital malformation of the urinary tract with a wide spectrum of presentation. The sporadic nature of this condition and its association with other anomalies makes evidence-based management difficult. We report two cases of triplication in association with the VACTERL syndrome, one developing pelvi-ureteric junction obstruction and the other vesico-ureteric reflux.

Magnetic resonance nephrography for planning of laparoscopic partial nephrectomy in a pediatric case of ureteral triplication

We present the case of ureteral triplication with vesicoureteral reflux into the lowest and middle pole in a 5-year-old girl. Magnetic resonance (MR) nephrography depicted loss of function of the lowest pole, which could not be assessed through MAG3 renal scan. Morphologic analyses revealed organ structure and vascular anatomy in superior quality. A laparoscopic partial nephroureterectomy of the lower pole was performed. Intraoperative findings correlated exactly with morphologic data obtained through MR nephrography. Dynamic MR nephrography should be considered as diagnostic tool of choice for selected kidney anomalies before surgery.

Ureteral Triplication And Contralateral Duplication With Vesicoureteral Reflux

Ureteral triplication is a rare congenital anomaly of the urinary tract. Since its first description, only about 100 cases have been reported in the literature. The association of ureteral triplication and contralateral duplication is even rarer. We reported a case of ureteral triplication and contralateral duplication with vesicoureteral reflux. The patient was a five-year-old girl with a history of recurrent urinary tract infections, dysuria and lower abdominal pain. Intravenous Pyelography (IVP) showed duplication of the right ureter and triplication of the left ureter. In the cystourethrogram there was vesicoureteral reflux at the lower pole of the right kidney. The patient underwent right lower to upper ureteroureterostomy and excision of the distal ureter. This is the second report of ureteral triplication in Turkey. The literature concerning this rare anomaly was reviewed.

Ureteral triplication with a contralateral duplication and ureterocele: a case report

We report a 10-year-old boy who presented with nocturnal enuresis. Radiological workup revealed a left ureteral triplication (Smith type 2) with a contralateral duplication and ureterocele. This presentation and its association are extremely rare. The clinical and radiological features are presented here as early diagnosis is important to avoid complications and future renal damage.
