Ureteral stenosis

Classification according to ICD-10
N13.5	Kink and stricture of the ureter without hydronephrosis
N13.4	Hydroureter
N13.3	Renal drainage disorder
ICD-10 online (WHO version 2019)

A ureteral stenosis is a narrowing ( stenosis ) of the ureter , even Harnleiterstenose called.

In a narrower sense, the term "ureteral stenosis" describes a congenital ureteral narrowing , in contrast to stricture as an acquired narrowing of the ureter.

Classification

Depending on the localization of the stenosis, a distinction can be made:

• at the transition from the renal pelvis to the ureter
  • Ureteral stenosis , also ureteropelvic stenosis or subpelvic stenosis , pyeloureteral obstruction
• in the course of the ureter
  • retrocaval ureter (congenital malformation with abnormal course of the ureter)
  • retroiliac ureter (congenital malformation with abnormal course of the ureter)
  • retroperitonaeal by compression in retroperitoneal fibrosis (Ormond's disease) or tumors
• in the area where it joins the urinary bladder
  • prävesikale stenosis , also Uretermündungsstenose or terminal ureteral stenosis

In the context of syndromes

In individual syndromes , ureteral stenosis can also appear as a criterion or clinical manifestation, for example in McKusick-Kaufman syndrome .

Differential diagnosis

Outflow obstructions by ureter valves (transverse folds of the mucous membrane with smooth muscles in the lumen) are to be distinguished.
