We treated 45 patients (46 ureteral stones) with a new pulsed dye laser. A 250 mu. fiber was used through a rigid (40 stones) or flexible (6) ureteroscope. Stones were in the upper (5 cases), middle (5) or lower (36) third of the ureter. Stone composition was calcium oxalate dihydrate (34 patients) or monohydrate (7), struvite (2) or uric acid (2). Of the calculi 36 (78%) were fragmented, including 14 that also required simultaneous basket removal of fragments. Ten stones were not fragmented: 6 because of the pure monohydrate composition and 4 due to malfunction of the laser. No damage to the ureteral wall was noted. Retrograde rigid ureteroscopy with laser lithotripsy was effective for lower and middle third ureteral stones. Flexible ureteroscopy with laser lithotripsy was effective (impacted stones) but difficult for upper third ureteral stones.
我们使用一种新型脉冲染料激光治疗了45例患者(46枚输尿管结石)。通过硬性输尿管镜(40枚结石)或软性输尿管镜(6枚结石)使用一根250μm的光纤。结石位于输尿管上段(5例)、中段(5例)或下段(36例)。结石成分包括二水草酸钙(34例患者)、一水草酸钙(7例)、磷酸镁铵(2例)或尿酸(2例)。36枚结石(78%)被击碎,其中14枚还需要同时用网篮取出碎片。10枚结石未被击碎:6枚是因为纯一水草酸钙成分,4枚是由于激光故障。未发现输尿管壁受损。逆行硬性输尿管镜联合激光碎石术对输尿管中下段结石有效。软性输尿管镜联合激光碎石术对嵌顿结石有效,但对输尿管上段结石操作困难。
