尿路狭窄是泌尿系结核最常见的并发症,多发生在多药联合抗痨治疗后,常侵害泌尿道解剖狭窄段,如肾小盏上下极、输尿肾孟连接处及输尿管膀胱开口处。逆行性气囊扩张配合sterting膜固定,是一有效的方法。作者治疗20例,17例首治成功,3例因狭程度较重导管无法进入而失败。17例成功者经七年随访仍有13例保持完好,2例同时复发,其中1例复发者再次行逆行性气囊扩并获成功,使用sterting膜固定规已三年,另一例再次治疗失败。作者认为狭发生的年龄和病损处血供状态是治疗能否成功的关键因素。
Narrow urinary tract is the most common complication of urinary tuberculosis, occurred in the multi-drug combination anti-tuberculosis treatment, often violations of the narrow anatomy of the urinary tract, such as the upper and lower renal calyx, ureter and renal connections Meng ureter and bladder openings . Retrograde balloon dilation with sterting membrane fixation, is an effective method. The authors of treatment of 20 cases, 17 cases of first successful, 3 cases failed due to narrow the scope of the catheter can not enter. Of the 17 successful cases, 13 remained intact and 2 had recurrent at the same time after seven years of follow-up. One of the patients who had recurrence underwent retrograde balloon dilatation and succeeded again. Sterting membrane fixation was used for three years and the other failed again. The authors conclude that the prevalence of blood supply at the age of stricture and lesion is a key factor in the success of treatment.
