“…MRI better characterizes urinary tract morphology and assesses differential renal function of each renal moiety, which enables the decision about further treatment. This is important since up to 50% of duplex kidneys are fraught with complications, like urinary tract dilation, calculi, urinary tract infection, dysuria, bladder dysfunction (ureterocele, ureteral ectopia), and need for surgical treatment [11,17,[22][23][24].…”

Duplex kidney is a urinary tract anomaly commonly associated with a wide range of primary and secondary parenchymal structural abnormalities. We present a unique comparison of US and MRI findings with histopathology following partial resection of duplex kidneys due to nephropathy. We examined a group of 21 children with duplex kidneys who were qualified for heminephrectomy (24 kidney units (KU)). All patients underwent US and MRI prior to the surgery. The imaging results were compared with histopathologic findings. In 21/24 KU, dysplastic changes were found on histopathology, including all with obstructive nephropathy and 7/10 specimens with refluxing uropathy. The loss of corticomedullary differentiation on US and increased signal on T2-weighted images (T2WI) on MRI were the imaging findings that best correlated with fibrosis. In children with megaureter, there were no statistical differences in histopathological findings between primary megaureter, megaureter with ureterocele, and megaureter with ectopia (p > 0.05). The extent of dysplasia of the affected pole correlated negatively with residual function in MRI. Kidney dysplasia and inflammation in the kidney with obstructive nephropathy are the most important histopathologic findings of this study. US is a valuable screening tool, and MRI enables morphologic and functional assessments of the nephropathy in duplex kidneys.

“…Nearly 60% of patients with duplex kidney are asymptomatic and need no treatment after birth. Patients with ectopic ureteral opening, ureteroceles, hydronephrosis, calcuil, urinary tract infection, or non-functional need surgical treatment ( 13 ). Treatment for duplex kidney needs to be individualized, and hemi-nephroureterectomy is the earliest technique used in duplex kidney therapy.…”

AimTo explore the treatment experience of the duplex kidney.MethodA case of the complete bilateral duplex kidney with severe hydronephrosis and ureterectasis in the upper moiety of the kidney diagnosed in the Department of Urology of Kunming Children's Hospital from 2021 to 2022 was retrospectively analyzed and relevant literature was reviewed.ResultsA 2-month-old baby girl was admitted to the hospital because of hydronephrosis of bilateral kidneys found by prenatal ultrasound for 3 months and fever for 3 days. After being given the relevant examinations, the girl was diagnosed with complete bilateral duplex kidneys with severe hydronephrosis and ureterectasis in the upper moiety, and urinary tract infection. The patient's urinary tract infection was poorly controlled after positive anti-infective therapy, so a bilateral ureterostomy was performed. After the surgery, urinary tract infection was soon cured. A bilateral ureteroureterostomy was performed 13 months later, and the patient recovered after 7 days.ConclusionCutaneous ureterostomy combined with late ureteroureterostomy for children with complete bilateral duplex kidneys with severe hydronephrosis in the upper moiety and ureter are not only beneficial to caregivers’ nursing after the operation, but also have significance for salvaging renal function.

“…Generally, duplex renal systems are asymptomatic and diagnosed incidentally. 2 Overall, understanding the complex etiology and manifestations of duplex kidneys is crucial for accurate diagnosis and appropriate management of associated complications such as vesico-ureteral reflux (VUR) and hydronephrosis. We have discussed a case of complete duplex system with hydronephrosis due to ureteric calculus.…”

Rare presentation of ureteral duplication: stone localization in the upper moiety

This case report describes a rare exception to the typical presentation of complete ureteral duplication, a relatively uncommon condition in comparison to single ureter or partial duplication. The patient presented with right flank pain and imaging revealed a duplex collecting system with a stone located in the upper moiety. Upper moiety complications, such as ectopic ureteric insertion and multicystic dysplastic moiety, are usually observed in duplex kidneys. Contrast-enhanced imaging and endoscopic treatment were utilized for accurate diagnosis and management. The case deviates from the expected pattern based on the Weigert-Meyer rule, emphasizing the importance of considering unique presentations in ureteral duplication cases.
