FONG ALDAMA, Francisco J  e  FERREIRA MORENO, Víctor G. Conservative surgery of anomalies associated to the ureteral duplication: 40 years of experience. Rev. Med. Electrón. [online]. 2012, vol.34, n.2, pp. 214-222. ISSN 1684-1824.

Objective: To expose the experience of the Urology Service of the Teaching Pediatric Provincial Hospital, in the treatment of the anomalies associated with the ureteral duplication. Methods: We retrospectively reviewed the medical records of 378 patients with Ureteral Duplication attended in our center in the period 1970-2010; the surgical treatment was applied in 26 cases, and 6 of them were pediatric cases; the last ones are analyzed in this work, taking into account data obtained from the Clinical Documentation Database of the centers involved. The conservative surgery (uretero-pyelostomy) was carried out in 5 patients of the 6 cases and in the other 1 case, an upper pole we made upper pole nephrectomy. Results: The ureteral duplication is a frequent pathology that determines a urinary stasis. The extra-vesical bifid ureter causes uretero-ureteral reflux. Conclusions: This surgical procedure is useful in the anomalies associated with the ureteral duplication. It should not be used when there are not possibilities of conserving the renal parenchyma.
