Dilatation of the upper urinary tract occurs in more than 80% of pregnant women during the last half of pregnancy. It is caused by compression of the ureter between the growing uterus and linea terminalis. A few patients develop pathological dilatation, flank pain and impaired renal function, a so-called symptomatic hydronephrosis. We have treated ten patients by means of internal drainage by using double pigtail catheters. Nine patients were completely relieved of their symptoms, and one reported marked reduction of pain. Five women complained of irritation of the bladder. In three of the women the intravesical portion of the catheter was shortened with success. Eight women kept the stent up to the time of birth. Two were removed two and eight weeks before delivery because of infection. There were no serious complications. Use of double pigtail catheters is a safe and simple way of treating symptomatic hydronephrosis of pregnancy.
在妊娠后半期，超过80%的孕妇会出现上尿路扩张。这是由于增大的子宫与耻骨梳韧带之间对输尿管的压迫所致。少数患者会出现病理性扩张、胁腹疼痛和肾功能受损，即所谓的症状性肾积水。我们通过使用双猪尾导管进行内引流治疗了10例患者。9例患者症状完全缓解，1例报告疼痛明显减轻。5名女性主诉膀胱受到刺激。其中3名女性成功缩短了导管在膀胱内的部分。8名女性将支架保留至分娩时。2名女性因感染在分娩前2周和8周取出了支架。没有出现严重并发症。使用双猪尾导管是治疗妊娠症状性肾积水的一种安全、简单的方法。
