Our experiences are reported with the "intraprostatic spiral" in 23 high-risk patients with prostatic adenoma. The intraprostatic spiral was used only in selected patients for medical indications. Patients confined to bed as well as those with detrusor instability or secondary dilatation of the upper urinary tract were excluded. 14 of our patients (60.8%) showed excellent voiding ability, without residual urine and all of them were fully satisfied with the functioning of the prostatic spiral. The longest indwelling time in this group is now about 36 months. 9 of 23 patients (39.2%) were not satisfied with their prostatic spiral. In all of them, the spiral had to be removed later on. Urinary stress incontinence was the main reason for removal. Two thirds of the patients who were not satisfied with the functioning of the prostatic spiral, had a marked decrease in detrusor function. This is a major reason for unsatisfying prostatic spiral function. On average, the prostatic spirals had to be exchanged after 15-18 months because of incrustation. Nearly all patients (21 of 23) showed asymptomatic bacteriuria.
我们报告了23例高危前列腺腺瘤患者使用“前列腺内螺旋装置”的经验。前列腺内螺旋装置仅用于有医学指征的特定患者。卧床患者以及逼尿肌不稳定或上尿路继发性扩张的患者被排除在外。我们的14例患者（60.8%）排尿能力极佳，无残余尿，他们都对前列腺螺旋装置的功能非常满意。该组患者最长留置时间约为36个月。23例患者中有9例（39.2%）对其前列腺螺旋装置不满意。所有这些患者后来都不得不取出螺旋装置。尿失禁是取出装置的主要原因。对前列腺螺旋装置功能不满意的患者中有三分之二逼尿肌功能明显下降。这是前列腺螺旋装置功能不理想的主要原因。由于结壳，平均15 - 18个月后就必须更换前列腺螺旋装置。几乎所有患者（23例中的21例）都有无症状菌尿。
