Re: Brisbane et al.: Fluoro-less ureteral stent placement following uncomplicated ureteroscopic stone removal: A feasibility study (Urology 2012;80:766-770)

摘要

TO THE EDITOR: We congratulate the authors for describing a novel technique of "fluoro-less" ureteral stent placement after uncomplicated ureteroscopic stone removal. However, certain queries need clarification. First, the need to place a double-J stent routinely after uncomplicated uretero-scopy is unnecessary. ' Second, the authors have determined the stent position by visualizing the upper stent coil with the renal outline on postoperative plain films taken at the follow-up visit. However, the authors do not mention the time of the first follow-up visit. This raises the possibility that in patients with a malpositioned stent, a significant delay could occur in correcting the position of a wrongly placed stent. Moreover, it has been shown that the median effective dose of radiation exposure for nonobese men undergoing ureteroscopy is 1.13 mSv, and this dose is approximately equivalent to the radiation from a plain radiograph of the kidney, ureter, bladder region. Thus, we believe it is necessary to have a single-shot of fluoroscopy at the end of the procedure for stent placement. In their study, the authors have used double-coil stents.
