“…Overall 31.8% of patients with double J stents were extremely bothered by urinary symptoms compared with 5.6% with Memokath 051 TM stents. Furthermore, 66.7% of patients with double J stents had a negative view toward living with their current urinary symptoms compared with 35.3% with Memokath 051 TM stents [33] . In addition to the above-mentioned benefits, repeated double J stent changes are avoided and pressure on hospital beds and costs (materials, hospital services, anaesthetic support, theatre, recovery etc.)…”

“…They also appear to have a lower incidence of associated lower urinary tract symptoms which are so common with double J stents, although we have not directly looked at this in our current study. Our group has previously compared QOL in patients with Memokath 051 TM stents versus double J stents [33] . In this study nearly 70% of patients with double J stents experienced urine frequency every 2 h or less compared with 47% of patients with Memokath 051 TM stents.…”

Introduction: The Memokath 051™ is a semipermanent inert metal alloy ureteric stent which can bridge strictures and, compared to double J stents, causes less bladder irritation and pain, is more resistant to external compression forces and may be more effective in patients with malignant ureteric obstruction. We present our experience with this novel stent in such cases. Methods: All suitable patients referred to us with malignancy-associated ureteric strictures over a 4-year period had ureteric Memokath 051™ stents inserted. Data on aetiology and position of the strictures as well as length of the Memokath stents used and their efficacy and complications were recorded prospectively. Results: 42 ureteric Memokath 051™ stents were inserted in 37 patients (mean age 64 years). 40.5% of strictures were related to gynaecological cancer, 21% to bowel cancer, 14% were post radiation, 14% occurred in prostate cancer patients and 9.5% were found in other cancers. The mean follow-up was 22 months (range 5–60 months). The main complications were stent migrations in 5, urinary tract infections in 3 and blockage of stent due to progressive transitional cell carcinoma of the ureter in 2 cases. Conclusion: Memokath 051™ ureteric stents are safe, effective and durable in the long-term treatment of malignant strictures.

“…Countries where healthcare is more competitive, demand-led and relatively autonomous, such as Austria, Germany, France and Italy, report much shorter waiting times [16] . Waiting times can be a major issue also for our stone patients who will have to tolerate temporary measures such as a JJ stent for long periods of time and will develop interim complications that could have been avoided with immediate treatment [17] . One option to avoid this, albeit at high costs, is to send patients to private contractors or foreign countries, should state provision fail or not be in time, as reported from Portugal.…”

Current Trends in Urolithiasis Treatment in Various European Health Systems

et al. 2015

Objective: In spite of readily available evidence-based guidelines on urolithiasis treatment, practical applications of treatments vary from country to country, or even within countries. The choice of treatment depends not only on the evidence, but often on general non-medical decision factors such as infrastructure, expertise, trends, patient demands, industry drive and reimbursement levels. In turn, many of these factors are interdependent and a result of the individual National Health System. Method: In an attempt to get a crude picture of trends and practices in stone treatment across Europe, a group of well-renowned international experts in the field were asked to reply to a set of standard questions relating to stone treatments, health systems and adherence to guidelines (level of evidence D = expert opinion). Results: The above-mentioned interdependencies showed a varying picture in different countries. Overall, there is a trend away from lithotripsy and toward ureterorenoscopy. However, the choice of treatment is largely dependent on the affordability of infrastructure. Urologists may make choices based on the national reimbursement system, too. Conclusion: Without claiming to represent a scientifically sound study, this survey represents an interesting insight into a representative cross-section of European urological current practices and trends in urolithiasis treatment.

“…A current study by Maan et al [8] revealed that ureteral stents (Memokath 051) are more tolerable than double-J stents concerning pain, lower urinary tract symptoms, and quality of life. In the literature, the follow-up periods of Memokath stents range from 11 to 17.1 months [9,10].…”

The insertion of two thermoformable ureteral titanium spiral stents (Memokath® 051) through ileal conduit due to bilateral ureteral stenosis distally has not been described in the English literature so far. We present the case of a young female patient with a history of ileal conduit urinary diversion due to congenital urinary bladder exstrophy, who had multiple previous surgeries and the insertion of two Memokath® ureteral stents in both ureters due to distal ureteral stenosis.
