尿管異所開口の7例

Abstract

Seven cases, 6 females and a male, of extravesical ureteral ectopia have been reviewed. In a girl, the ectopic ureter drained the upper pole moiety of the duplicated system. There were 6 patients with single ectopic ureters, including a case with absence of the contralateral kidney. Careful inspection of the vaginal wall and endoscopic examination of the urethra revealed the ectopic ureteral orifice in most cases. The use of renal scan was helpful in the diagnosis of a poorly functioning kidney which could not be demonstrated on intravenous urography. When associated with a poorly functioning dysplastic kidney, it was managed by nephroureterectomy. Ureteral reimplantation was performed in 2 cases, but no improvement of continence was noted in the case of the solitary kidney.
