Bifid Ureter

Introduction. Urogenital and vascular anomalies, including a left duplex kidney and a left aberrant renal artery that gave rise to the left ovarian artery, were observed in a 77-year-old female cadaver during a routine dissection. Description. A left aberrant renal artery, which gave rise to the left ovarian artery, was observed originating from the aorta 4 cm below the left renal artery. Two independent contributions to a bifid ureter were found originating from the hilum of the left kidney. These two contributions descended 12.4 cm and 10.6 cm, respectively, posterior to the left aberrant renal artery and lateral to the left ovarian artery before uniting anterior to the psoas major muscle to descend 12.7 cm to the bladder. Significance. While the duplex kidney is a relatively common congenital anomaly that can be asymptomatic, it can also potentially be associated with compression of renal vasculature or the ureter. Ureteral compression can then result in several pathologies including reflux, urinary tract infection (UTI), ureteropelvic junction obstruction, or hydronephrosis. Compression of renal and ovarian vasculature can result in altered blood flow to the kidney and ovary, potentially causing fibrosis, atrophy, or organ failure. Current imaging techniques alone are insufficient for correct diagnostics of such complications, and they must be supplemented with a thorough understanding of the respective anatomical variations.

Abstract Purpose This study aimed to standardize the operative technique of indocyanine green (ICG) near-infrared fluorescence (NIRF) laparoscopic partial nephrectomy (LPN) and compare it with the standard technique. Methods In the last 4 years, we performed 22 LPN (14 right-sided, 8 left-sided) in children with non-functioning moiety of duplex kidney. Patients included 12 girls and 10 boys with a median age of 3.9 years (range 1–10). Patients were grouped according to the use of ICG-NIRF: G1 included 12 patients operated using ICG-NIRF and G2 included 10 patients receiving the standard technique. We standardized the technique of injection of ICG in three different steps. Results The median operative time was significantly lower in G1 [87 min (range 68–110)] compared with G2 [140 min (range 70–220)] (p = 0.001). One intra-operative complication occurred in G2. At post-operative ultrasound (US), the residual moiety was normal in all patients. An asymptomatic renal cyst related to the site of surgery was visualized at US in 8/22 (36%), with a significantly higher incidence in G2 (6/10, 60%) compared with G1 (2/12, 16.6%) (p = 0.001). Renogram demonstrated no loss of function of residual moiety. No allergic reactions to ICG occurred. Conclusion ICG-NIRF LPN is technically easier, quicker, and safer compared with the standard technique. The main advantages of using ICG-NIRF during LPN are the clear identification of normal ureter, vasculature of non-functioning pole, and demarcation line between the avascular and the perfused pole. The main limitation of ICG technology remains the need for specific laparoscopic equipment that is not always available.

Background: A 76-year-old male presenting with macroscopic haematuria was found to have a lobulated mass infiltrating along the urothelium at the site of insertion of the upper moiety of a complete duplex right kidney. Suspected of being upper tract urothelial carcinoma, cystoscopy, bilateral retrograde pyelograms and transurethral resection of bladder tumour were attempted. Intra-operative findings revealed no tumour burden in the bladder or left ureter. The insertion of the upper pole moiety of the right ureter was not identified intra-operatively. Pelvic MRI demonstrated a markedly dilated upper pole moiety of the right ureter with a soft tissue mass in its distal aspect. Interestingly, the distal portion of the ectopic upper pole moiety was found to insert into the bladder neck. Objective and Methods: We report on an unusual case of upper tract urothelial carcinoma arising from the upper moiety of a complete duplex kidney. Our aim was to demonstrate the importance of thorough investigation of suspected urothelial carcinomas occurring in association with variant upper tract anatomy. Results and Conclusion: This case demonstrates the importance of thorough radiological and endourological investigation of suspected upper tract urothelial carcinoma and the various congenital abnormalities that may complicate the surgical management of this common malignancy. Level of evidence: 4 (case report)
