To present an improvised method for repositioning a proximally displaced stent using only a cystoscope and a guidewire.
A Glidewire guidewire (Boston Scientific) was passed through a cystoscope and into the distal ureter, and manipulated up the ureteral stent into the renal pelvis, reflected, and passed antegrade down the ureter and into the bladder. The guidewire was then grasped in the bladder, clamped at the penis, and retracted, pulling the stent back into the bladder.
The patient proceeded with lithotripsy, and the stent was removed in 2 weeks without complication.
Methods at retrieving proximally displaced ureteral stents after deployment have been previously reported; however, these methods necessitated access to a ureteroscope and special graspers/baskets that may not be available in an outpatient surgical center setting. Here, an improvised method for stent repositioning using only a cystoscope and a guidewire allowed successful retrieval of a proximally migrated stent.
介绍一种仅使用膀胱镜和导丝重新定位近端移位支架的临时方法。
将 Glidewire 导丝（波士顿科学公司）穿过膀胱镜进入输尿管远端，并操纵导丝进入肾盂，反射后沿输尿管逆行进入膀胱。然后将导丝在膀胱内抓住，在阴茎处夹住并缩回，将支架拉回膀胱。
患者继续进行碎石术，2 周后无并发症取出支架。
以前已经报道了在部署后取回近端移位输尿管支架的方法；然而，这些方法需要使用输尿管镜和特殊的抓握器/篮，而这些可能在门诊手术中心无法获得。在这里，仅使用膀胱镜和导丝的支架重新定位的临时方法成功地取回了近端迁移的支架。
