Abstract
INTRODUCTION Discovered in 1960, ketamine hydrochloride is a glutamatergic N‐methyl‐D‐aspartate antagonist that has been used for decades as a short‐acting, but powerful, dissociative anaesthetic employed in both human and veterinary [...]
: Aims: Refractory ketamine‐induced uropathy (KU) (RKU) has devastating effects on the lower urinary tract leading to ureteral obstruction and even renal failure. The only effective treatment for RKU is major surgical reconstruction or urinary diversion. Nevertheless, there is a paucity of awareness about this destructive condition; the aim of this study is to conduct a narrative systemic review of all surgical outcomes of RKU. Methods: This is an English language literature review of surgical outcomes in KU patients who underwent reconstructive lower urinary tract surgery or urinary diversion through 5 August 2022. Two independent researchers assessed the relevance of each paper and disputes were settled by a third party. In‐vitro, animal studies, letters to the editor and papers that did not evaluate surgical outcomes were excluded. Results: Of the 50 763 identified articles, 622 were relevant based on title, 150 based on abstract, but only 23 papers were relevant by content. In all, 875 patients were documented as having KU, of whom 193 (22%) underwent reconstructive surgery. The data were disconcerting, as the apparent rapid progression from the beginning of KU to end‐stage bladder was only a 1‐year difference of ketamine abuse between those patients who required surgery (4.4 years) and those that did not (3.4 years). Conclusions: The data suggest that the time interval from the beginning of ketamine‐induced uropathy to the end‐stage bladder may be measured in months, confounding decision making. There is a dearth of literature about KU, and more research is needed to better understand this pathology.
