Urinary incontinence is a rare complication of Memokath® ureteric stent insertion.

INTRODUCTION The Memokath® ureteric stent is a thermo-expandable titanium-nickel alloy.(1) Its use is not recommended in stone formers and patients with functional stenosis.(2) Unlike conventional plastic ureteric stents, it is a semi-permanent prosthesis. However, should removal be required simply flushing the stent with cold water returns it to a soft and pliable form. As these stents do not promote tissue ingrowth, removal is atraumatic. The stent should not extend beyond the ureteric orifice into the bladder as this may result in bladder irritability, reflux and associated flank pain.(3) Herein we report the unusual case of a 49-year old man who presented with urinary incontinence following insertion of a Memokath® ureteric stent three weeks prior.
