Early encrustation of a ureteric metallic stent managed by robotic assisted extraction and pyeloplasty

Abstract

Ureteral obstruction is a commonly encountered condition during daily practice. The mainstay of treatment for ureteral obstruction is drainage and relief of the obstruction, regardless of the etiology. Drainage using the traditional ureteral Double J stent has been recently challenged with new ureteric stent that proposed to have better durability and patient quality of life, particularly in cases that require prolonged insertion. One of these options are the ureteric metallic stents, such as Memokath, although uncommon, encrustation of Memkath can occur, leading to early removal. Here we present a case of 28-year-old gentleman with recurrent right pelviureteric junction obstruction, who had undergone pyeloplasty in childhood, The patient was hesitant to undergo redo pyeloplasty and opted for balloon dilatation with Memokath insertion. however early encrustation occurred leading to worsening of the condition and pain, and he was subsequently managed with robotic assisted laparoscopic Memokath extraction and dismembered pyeloplasty.
