A 31-year-old multigravid woman with a history of severe endometriosis involving the urogenital tract and complete duplication of the right renal collecting system, as well as a right ureterovaginal fistula, presented for evaluation and surgical consult [ncbi.nlm.nih.gov]

Aberrant renal arteries are present in about 30% of individuals. Aberrant renal arteries to the inferior pole cross anteriorly to the ureter and may cause hydronephrosis [ 8 ]. [pulsus.com]

Presentation One month history of burning micturition. Ultrasound (not included) revealed a left sided double ureter but the entire course could not be traced. Hence an IVU was performed. [radiopaedia.org]

The patient underwent laparoscopic ureteroneocystostomy and vesicopsoas hitch for the treatment of infiltrative endometriosis with a double ureter. [ncbi.nlm.nih.gov]

Ureteric stents are in most instances temporary and must be removed from the body after definitive treatment is completed. Occasionally, events can occur where communication and follow up is lost. [kidneystoneclinic.com.au]

The cost-effectiveness of the MS seems to be appropriate for long-term treatment. [indianjurol.com]

Treatment and prognosis Surgical intervention is usually not indicated in absence of reproductive difficulties. [radiopaedia.org]

Finally, combined treatment modalities and complete management of the disease can give the patient a better prognosis and an increased chance of survival. [karger.com]

Prognosis As long as damage to the kidneys from infection or back pressure has not become significant, the surgical repair of troublesome ureteral defects produces excellent long-term results in the great majority of cases. [healthofchildren.com]

With appropriate management, the ultimate prognosis of duplicated ureter, ureteral ectopia, or ureterocele is excellent. Pathophysiology Ureteral embryology is fundamental in understanding abnormal development of the ureter. [emedicine.medscape.com]

Etiology Clinical features Diagnostics Ultrasound imaging of the kidneys and bladder First-line imaging modality Detects anatomical abnormalities Renal ultrasound is warranted for all children with recurrent UTIs or UTI in children 24 months of age. [amboss.com]

The MS provided sufficient kidney drainage for 4 months. [20] Nagele et al. studied 14 patients (18 collecting systems) with ureteral obstruction of both benign (5 ureters) and malignant etiologies (13 ureters). [indianjurol.com]

Epidemiology United States statistics In autopsy series, the incidence of ureteral duplication is estimated at slightly less than 1%. In studies of young children with UTIs, the incidence of duplication rises to 8%. [emedicine.medscape.com]

EPIDEMIOLOGY  Incidence of ureteral duplication- 1% (autopsy series).  Ureteroceles- 1 per 5000-12000 population; 10% bilateral, 60-80% ectopic, 80% a/w upper-pole ureter of a duplex system. [slideshare.net]

This chapter will discuss the terminology, incidence, embryology and pathophysiology of duplex kidneys. The management of reflux into duplex kidneys, ectopic ureters and ureteroceles will then be discussed. [pediatricurologybook.com]

Close monitoring and follow-up is very important and may contribute to the prevention of complications in these patients. [ncbi.nlm.nih.gov]

Prevention The cause of congenital ureter anomalies is not known. There is no prevention. Resources BOOKS Colberg, John W. "Urologic Abnormalities of the Genitourinary Tract." Chapter 21, section 16, in Rudolph's Pediatrics, 21st ed. [healthofchildren.com]

The valve that normally prevents urine reflux is called the vesicoureteral valve. The danger for children with VUR is that a resulting urinary tract infection (UTI) weakens the urinary tract’s ability to prevent bacteria from entering the kidney. [denverurology.com]
