Presenting A Rare Case of Duplex Left Kidney with Ectopic Insertion of Lower Moiety Ureter into Prostatic Urethra

Background: Duplex collecting systems are the most common variant of renal anatomy with estimated prevalence ranging between 0.3% and 6% of the population Casereport: We present a case of a30 years old male presenting with dull aching Pain in left lumbar region since 6 months. He was evaluated with Ultrasound (USG) abdomen and Pelvis, Micturating Cystourethrogram (MCU) and Contrast enhanced computed tomography (CECT) of Kidney, ureter, bladder (KUB) and was found to have Duplex left kidney with double ureters and ectopic insertion of the upper pole ureter into the prostatic urethra. Discussion: USG allows exclusion of a duplex kidney and of obstruction due to a ureterocele. Renal scintigraphy is required to assess renal function, and Computed tomography (CT) may be useful on occasion in locating a small, poorly functioning dysplastic kidney. Magnetic Resonance (MR) urography has an advantage over USG and IVU in that it is capable of demonstrating ectopic extravesical ureteric insertions, thereby providing a global view of the malformation. Conclusion: Understanding embryology, development of ureters and weight-Meyer law helps in investigating a case of double ureter. Radiological investigations may be performed in sequence depending on cases to come to diagnosis.
