Our first option to repair it is open surgery, performed in 27 patients. Instead of this, we choose endoscopic techniques (balloon dilatation) as an alternative in patients with high-surgical risk or with re-stenosis after surgery, with poor results. The aim of our study is to evaluate the efficacy of Memokath 051 stent in high surgical risk patients and in those in which the surgery or dilatations have failed. METHODS Prospective study over 11 patients transplanted in 2004-2011, who had ureteral stenosis with renal function repercussion. Indications for metallic stenting were: re-stenosis after surgical treatment (3 patients) and severe comorbidities contraindicating surgery (8 patients). All patients had a nephrostomy placed previously and at least 2 failed endoscopic balloon dilatations. Antegrade pyelography showed stenosis in distal ureter in 9 cases and in pyeloureteral union in 2. Follow-up after was made with serum creatinine levels, simple X-ray, ultrasonography and renal scintigraphy in some cases. RESULTS Between February 2009 and February 2012, 12 stents were placed in 11 patients through anterograde transrenal approach. Radiologic control after the procedure showed successful resolution of the stricture in all the cases. We observed 2 transitory haematuria, but there were no major immediate complications in any case. As a long term complications, we found 1 stent migration after 30 days and one patient with a new proximal stenosis after 7 months, both of them needing stent replacement. One patient had spontaneous stent migration to the bladder after 29 months, without needing a new stent because of normal renal function. Finally, one patient had severe chronic allograft dysfunction with recurrent acute pyelonephritis and we decided to perform transplantectomy. Due to their severe comorbidities, 2 patients died with functional stent in situ (after 5 and 15 months). Another 2 patients with non-obstructive chronic allograft dysfunction, were reintroduced to haemodialysis program after 7 and 18 months, and died later because of their diseases. After a mean follow-up of 52.5 months (33-69), we have 6 patients with stable renal function and without clinically significant hydronephrosis. CONCLUSIONS The management of ureteral stenosis with ureteral stent Memokath 051 is minimally invasive, safe and effective, and can be a long-term alternative to surgical treatment in selected cases. © 2015 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 193Issue 4SApril 2015Page: e1017 Advertisement Copyright & Permissions© 2015 by American Urological Association Education and Research, Inc.MetricsAuthor Information Helena Vila Reyes More articles by this author Lluis Riera Canals More articles by this author Joan Dominguez Elias More articles by this author Laia Pujol Galarza More articles by this author Eladio Franco Miranda More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
