New coaxial balloon dilators with standard urologic tip configurations have been designed for use in urethral strictures. Balloon dilatation provides several advantages over conventional dilatation of strictures including improved access and decreased mucosal trauma due to a low silhouette, adjustability of diameter and rigidity, decreased instrumentation, and facilitation of intermittent self-dilation by the patient. The instruments were evaluated in 51 strictures (41 patients) as both a dilator and a calibrator. All catheters were located across the stricture easily (although two required filiform attachments). All clinical goals were achieved, and no complications were identified. Two patients were started on a program of intermittent self-dilation after internal urethrotomy with good results. It is our initial clinical impression that slow, gradual dilation of strictures is superior to rapid, abrupt dilation. This can only be practically achieved with balloon dilators.
新型带有标准泌尿科尖端配置的同轴球囊扩张器已设计用于尿道狭窄。与传统的狭窄扩张相比，球囊扩张具有几个优点，包括因低轮廓而改善的进入通道、减少粘膜创伤、直径和硬度的可调节性、减少器械操作以及便于患者进行间歇性自我扩张。这些器械在51例狭窄（41例患者）中作为扩张器和校准器进行了评估。所有导管都能轻松穿过狭窄部位（尽管有两例需要丝状附件）。所有临床目标均已实现，未发现并发症。两名患者在内切术后开始进行间歇性自我扩张计划，效果良好。我们的初步临床印象是，缓慢、渐进性地扩张狭窄优于快速、突然性扩张。这只有使用球囊扩张器才能实际实现。
