Extra-Anatomic Stents in Ureteric Obstruction: Our Experience.

Objectives: To present our experience of the Detour extra-anatomic stent (EAS; Porges-Coloplast, Denmark) to bypass ureteric obstruction. Use of the EAS is indicated in patients with complex ureteric strictures or malignant disease, where long-term nephrostomy drainage is undesirable.

Materials And Methods: Between December 2001 and October 2017, 20 Detour EAS were implanted into 13 patients.

Do stones still kill? An analysis of death from stone disease 1999-2013 in England and Wales.

Objectives: To analyse the trends in the number of deaths attributable to urolithiasis in England and Wales over the past 15 years (1999-2013). Urolithiasis has an estimated lifetime risk of 12% in males and 6% in females and is not perceived as a life-threatening pathology. Admissions with urinary calculi contribute to 0.

Stabilization of renal deterioration caused by bladder volume dependent obstruction.

Purpose: Previously published data from our unit show the detrimental effect of excessive bladder filling at normal pressure on renal function in chronically dilated renal units. Synchronous cystometry and dynamic renography identified a critical volume of filling that prevents upper tract drainage. In this followup study we determined whether maintaining bladder volume below this critical level would halt renal deterioration.
