Experience of complete duplication of the collecting system

Abstract

Twenty-three cases of complete duplication of the collecting system are reviewed. The type of ureteral hiatus was retrospectively studied to assess its relation to various abnormalities of the duplex system. It was stressed that the hiatal concept is quite important in understanding the multifarious problems of the pathophysiology of ureteral dilation, surgical management and faulty embryogenesis of the kidney and ureterovesical junction of the duplex system.

A LIFE IN UROLOGY: Privilege, Obligation and Reward

“…1.2 Disorders of UVJ other than VUR: The role of ureteral sheath in megaureter, be it in refluxing MU or primary MU, was addressed both morphologically and functionally [6]. In view of USh involved in the structure of ureteral hiatus, the role of differences in the hiatus, be it common(C), intermediate (I) and/or separate (S) in duplex anomaly was analyzed [7]. In ectopic ureter this was more relevant than ectopic orifice in associated renal anomaly and also in its surgical management [8].…”
