A report of 21 cases of ureteric duplication / 中华泌尿外科杂志

ABSTRACT

ObjectiveTo study the diagnosis and treatment of ureteric duplication.Methods21 cases of ureteric duplication treated by open operation from Dec.1988 to Dec.2000 were reviewed,of which 14 cases were unilateral complete ureteric duplication (UCUD),4 unilateral incomplete ureteric duplication (UIUD) and 3 bilateral complete ureteric duplication (BCUD).All the patients have been followed up for more than 6 months.ResultsUpper pole nephroureterectomy was carried out for 10 UCUD patients and ureterovesicostomy for 4.Ureteroureterostomy was conducted for the 4 UIUD.Of the 3 BCUD cases,unilateral upper pole nephroureterectomy was undertaken for 2 and unilateral ureterovesicostomy for 1.In all these 3,upper urinary tract infection symptoms have been alleviated.In the 18 unilateral ureteric duplication,no symptoms of upper urinary symptoms or vesico-ureteral reflux has been noted.The deformed upper renal pole has not been resected in 9 cases,only 1 of which treated by simple ureterovesicostomy underwent kidney pole resection because of pyonephrosis.ConclusionsImaging studies are important for the correct diagnosis.Adequate evaluation is required for the proper assessment of operative stategy and long term follow up is necessary.
