Introduction: The urachus is a fibrous remnant of the sinus and urogenital allantois, a tubular epithelial structure located in the midline that connects the anterosuperior part of the urinary bladder with the navel during embryogenesis. Alterations resulting from the incomplete regression of this allantoid remnant include four different types of remnants depending on the persistent segment of the urachus. An uracal cyst is a persistent section in the middle portion of the urachus filled with fluid derived from the epithelial lining. Objective: To know the incidence, diagnosis and treatment of urachal cysts. Case report: A 42-year-old male patient presented to the clinic for a condition of seven months of evolution characterized by intermittent infraumbilical abdominal pain. Extension studies demonstrated the presence of a cystic-appearing tumor between the anterior bladder wall and the umbilical scar, and underwent surgery with ureter cyst excision and partial cystectomy, finding a cystic remnant with dimensions of approximately 12 X 5.0 cm. Conclusions: The congenital pathology of the urachus requires a good anatomical and embryological understanding for its adequate diagnosis and management. [ABSTRACT FROM AUTHOR]

Introduction: Simple renal ectopia is defined as a mature kidney that does not reach its normal location in the renal fossa from its origin, during embryonic development. The average incidence in autopsy series is 1 in 900 cases and 0.003% in prenatal ultrasounds with greater recognition in women and preference for the left side. Clinical case: A 21 yeasr old woman with no pathological personal history, presented to the urology clinic for a condition of one year of evolution, characterized by left lower abdominal pain. An abdominal magnetic resonance imaging (MRI) scan showed an empty left renal fossa and a left lumbar ectopic kidney, malrotated and hypotrophic, anterior to the left iliac vessels, with an aberrant arterial vasculature. Discussion: Most ectopic kidneys are asymptomatic; however, the abnormal position of the kidney determines an atypical pain pattern. The arterial and venous network is abnormal and its vascular pattern depends on the final position of the kidney. The kidney can be irrigated in its entirety by multiple anomalous branches. Conclusion: Although most ectopic kidneys are asymptomatic, abdominal complaints secondary to the abnormal vasculature may be present. [ABSTRACT FROM AUTHOR]
