ARZE, Lorena; VISCAINO, Aldo  y  HERRERA, Marcela. Cecoureterocele, a case report. Gac Med Bol [online]. 2016, vol.39, n.1, pp.30-33. ISSN 1012-2966.

A cecoureterocele is an ectopic ureterocele, congenital anomaly of the distal ureter at the uretero-vesical junction, consisting in a closed membranous pouch which protrudes through the urethra into the vagina. We present a five months old, 6 kg girl, admitted for assessment and management of a dark red mass protruding through the vagina. On examination, good general health. BP 93/56, HR 134 bpm, RR 38x´, T 36o, O2 Sat 96 %. Renal ultrasound: parahiliar liquid shadow in the left kidney sugesting a duplicated incomplete collecting system with a dilated proximal segment. Bladder ultrasound: dense liquid shadow related to the urinary tract sugesting a ureterocele. DMSA renal gamma scan: poor captation in the upper pole of the left kidney. DTPA isotopic renogram: Retention of the tracer in the left renal pelvis. Surgical correction consisting in a left upper pole partial nephrectomy, separation and distal section of the dilated ureter and resection of the ureterocele. Good postoperative course, discharged two days later. A cecoureterocele is an uncommon congenital malformation of the urinary tract commonly associated with other surgically correctable malformations. We recomend to consider this posibility in the differential diagnosis of any mass protruding through the vagina.
