Memokath for treating ureteric stricture post cryoablation of renal mass: A case report of rare complication and proposed alternative management

[摘要] The use of cryoablation in the management of small renal masses is widely acceptable. Although rare but ureteral injury during the procedure with subsequent stricture formation can result in devastating effects on renal function. On the other hand, the management of such strictures requires reconstructive surgery as gold standard. Unfortunately, in some cases the reconstructive surgery might not be feasible, and the treatment usually is ureteral stent insertion that need to be changed regularly. Here we present a case of a 53-year-old gentleman who developed an upper ureteric iatrogenic stricture post cryoablation in which the reconstructive surgery was not feasible due to high procedural risk. We used metallic ureteral stent (Memokath) instead of regular ureteral double J stent. We found that if the reconstructive surgery is not possible the usage of Memokath in treating iatrogenic ureteral strictures is associated with better quality of life, lower costs and a similar functional outcome when compared to ureteral double J stent that needs regular frequent changes.
