Treatment using a metallic spiral was attempted on 22 patients. They had urinary retention in 16 cases and dysuria in 6. In 21 of them, the spiral was successfully placed under transrectal ultrasound control. In all 21 patients, voiding was possible immediately after placement of the spiral. As for urodynamic study, urine volume was 100-230 ml (mean: 172 ml), maximum flow rate was 13-21 ml/sec (mean: 17.3 ml/sec), and average flow rate was 4-12 ml/sec (mean: 8.2 ml/sec). Residual urine volume was less than 30 ml in 20 patients and 200 ml in one. As for complications, proximal migration of the spiral was observed in 6 patients. In 4 of them, the new spiral was placed. Perineal discomfort was seen in 3 patients, in 2 the spiral was removed. Pyuria associated with bacterial infection did not continue after the treatment in patients having a catheter. Severe urge incontinence and encrustation were never seen. The above findings suggest that, though a longterm study has not done, this treatment could be an effective treatment particularly for the elderly patients with general complications and/or who require removal of an indwelling catheter for clinical or social reasons.
对22例患者尝试使用金属螺旋装置进行治疗。其中16例存在尿潴留，6例有排尿困难。在21例患者中，螺旋装置在经直肠超声引导下成功置入。在这21例患者中，螺旋装置置入后立即能够排尿。关于尿动力学研究，尿量为100 - 230毫升（平均：172毫升），最大尿流率为13 - 21毫升/秒（平均：17.3毫升/秒），平均尿流率为4 - 12毫升/秒（平均：8.2毫升/秒）。20例患者残余尿量少于30毫升，1例为200毫升。关于并发症，6例患者观察到螺旋装置近端移位。其中4例重新置入了新的螺旋装置。3例患者出现会阴部不适，2例移除了螺旋装置。留置导尿管的患者治疗后与细菌感染相关的脓尿未持续存在。从未出现严重的急迫性尿失禁和结痂。上述结果表明，尽管尚未进行长期研究，但这种治疗可能是一种有效的治疗方法，尤其适用于有一般并发症和/或因临床或社会原因需要拔除留置导尿管的老年患者。
