DJ stent is considered the most commonly used stent to relieve ureteric obstructions. However it has certain limitations, such as their need of frequent exchange every 3-6 months, which greatly reduces quality of life in comorbid patients, stent related symptoms and complications such as Urinary Tract Infections (UTI), stent related Lower Urinary Tract Symptoms (LUTS), hematuria, infection and stent occlusion.  Alternatively, a novel long lasting  thermoexpandable  nickel–titanium alloy stent ( MemokathTM  051) has been used to relieve ureteral obstructions in highly comorbid patients, with multiple reported advantages, such as longer durability compared to the regular DJ stents reaching up to a year, which avoids the need of multiple admissions for DJ stent exchanges. Furthermore, the  Memokath  045 has been used in specific cases of urethral strictures.

Our paper aims to report the first experience of  Memokath  051 and  Memokath  045 stent with ureteral and urethral strictures outcome  in the region.

A Total 21 patients received 21  Memokath  stents by cystoscopy, all insertion procedures were uneventful. Mean age was 52.42 years. 11 of the cases (52.4%) had ureteral stricture, and 10 cases (47.6%) had urethral stricture. Of the stents placed for benign and malignant strictures, the stent remained in situ for a mean of 14.33 months & 18.7 months, respectively.  Of all the 21 cases that had the  Memokath  stent placed, 4 strictures (20%) were resolved after the removal of the stent, of which 3 were urethral strictures & 1 ureteric stricture. while 16 strictures (80%) persisted afterwards, 1 patient deceased with the  Memokath  stent remaining in situ. 3  Memokath  stents placed in transplant ureters remained functioning for a mean of 24.33 months Urethral  Memokath  stents remained functioning for a mean of 14.54 months  Of the 11 ureteric stents, 4 stents were removed due to stent migration, 4 removed due to stent blockage/encrustation. 2 stents were removed as planned, 1 stent removed due to febrile UTI. UTI was the most common cause of removal of urethral stents.

Our experience reports a  favourable  outcome of the stent in ureteric strictures, and especially in transplant ureters. The stents remained functioning for an adequate time, favoring its use over the regular DJ stents. We also report similar complication rates as compared to other published studies. Additionally, Our study shows that  Memokath  stent is a reliable alternative in complex urethral stricture cases with an impressive functioning duration and similar rate of complications as reported in other studies.

We retrospectively reviewed the medical charts of 21 patients who had received a 21  Memokath  stent 051 and 045 between January 2013 and December 2020, 10 patients had the  Memokath  inserted for urethral strictures, and 11 inserted for ureteral obstructions.  Patient demographics and Perioperative data was then collected and analyzed through SPSS. All of our patients who had ureteral stricture had a Double J stent placed prior to the  Memokath  051 in the past, and all the patients with urethral strictures had underwent multiple dilatation and VIU (Visual internal urethrotomy) and/or  urethroplasty  in the past.
