Anastomosis ureteroureteral: una alternativa para pacientes con enfermedad asociada a doble sistema colector

Abstract

Introduction and objectivesDuplicated collecting system is a common congenital renal disorder and has an incidence of 0.8%. There are several treatment options available for the severely dilated ureter or reflux associated with a duplicated system, including hemi-nephrectomy, uretero-ureteral anastomosis, and ureteroneocystostomy. The aim of this article is to present our experience of the uretero-ureteral anastomosis as an alternative for patients with renal pathology associated with duplicated collecting system. Materials and methodsA retrospective review was performed, between July 2011 and April 2014, on the medical records of patients with duplicated collecting system and associated disorders and who underwent uretero-ureteral anastomosis. Demographics, such as age, sex, laterality and postoperative outcomes were analysed. ResultsA total of 10 patients underwent uretero-ureteral anastomosis, of whom 7 were female and 3 were male. The mean age of patients was 5 years (1-13 years). There were 6 patients with right pathology; 9 patients had urinary tract infection, and one had permanent urinary incontinence. Ectopic ureter was diagnosed in 4 patients, 3 patients had intravesical ureterocele and 3 had vesicoureteral reflux to the lower system. Seven upper to the lower anastomosis system and 3 lower to the upper system anastomosis were performed. All were made by 2cm inguinal incision, and all patients had a double J catheter bypass. ConclusionsThe uretero-ureteral anastomosis is a reliable and safe alternative with low morbidity. It is effective for the treatment of patients with duplicated collecting system associated to renal pathology.
