ABSTRACT
Objective: Among the most common causes of the intrinsic obstruction in pieloureteral union includes the mucus folds in the valves, the persistence of the fetal circumvolutions and the high ureteral polyps. Clinical case: Female patient, 7 years of age that came to the office with a history of recurrent urinary infection of approx 6 months of evolution, with multiple treatments. An excretory urogram was performed, along with a cystography, and a kidney ultrasound. An obstruction of the pieloureteral union was diagnosed in the left kidney. A renal gammagram was performed and the renal function was adequate. A surgical correction was performed utilizing the Anderson and Hynes dismembranizing technique sending the pieloureteral junction to the pathology lab. The histopathology results: the pieloureteral junction showed mucus folds of the urothelium that projected towards the lumen. Conclusion: Reviewing the literature, there were 31 cases reported that were compatible with the Wall and Wachter criteria, with presence of smooth muscle in the valve. There was pathological evidence of obstruction before the valve, and no evidence of obstruction of the ureter past the valve. The proposed treatments have been the surgical resection of the affected segment, endourologic treatment and laparoscopy. Literature was reviewed and we attached the description of an infrequent case.REFERENCES
