Six patients with acute urinary retention and 2 with prostatic obstruction and urge incontinence were treated with an intraurethral prostatic spiral and underwent pressure-flow studies 51 days (median) later. Evaluation of pressure-flow parameters and pressure-flow plots by different methods gave conflicting results regarding the presence of infravesical obstruction; 6 patients showed no voiding symptoms and in 2 patients only moderate irritative symptoms remained. The spiral allowed unobstructed voiding and is a good alternative to an indwelling urethral catheter. We recommend insertion of a spiral in patients with urinary retention if the waiting period for TURP is long or if the patient is unfit for surgery.
6例急性尿潴留患者以及2例伴有前列腺梗阻和急迫性尿失禁的患者接受了尿道内前列腺螺旋装置治疗，并于51天（中位数）后进行了压力-流率研究。采用不同方法对压力-流率参数和压力-流率图进行评估，对于膀胱颈以下梗阻的存在得出了相互矛盾的结果；6例患者无排尿症状，2例患者仅残留中度刺激症状。该螺旋装置可实现无障碍排尿，是留置尿道导管的良好替代方案。我们建议，对于需要长时间等待经尿道前列腺切除术（TURP）或不适合手术的尿潴留患者，可插入该螺旋装置。
