Urologists successfully use ureteral stents to protect the ureterovesical anastomosis in nontransplant patients.
We determined the value of ureteral stents in transplant patients. The frequency of urological complications (leaks, obstructions and urinary tract infections) was compared in a prospective randomized series of 194 kidney transplantations (97 with and 97 without a double pigtail ureteral stent).
In the stent group 1 patient had a urinary leak and 35 had urinary tract infections (including 2 cases of Corynebacterium cystitis). In the no stent group 6 patients had urinary leaks, 4 had obstructions and 32 had urinary tract infections. The 1-year patient and graft survival rates were similar in both groups, and renal function at 1 year was also similar (229 versus 208 mumol./l. creatinine in the stent and no stent groups, respectively). A small number of stent related complications occurred (2 stent breakages and 1 stent migration). No stones formed in any case.
Ureteral stent insertion significantly decreases the rate of vesicoureteral leakage and obstruction in renal transplantation.
泌尿外科医生成功地使用输尿管支架来保护非移植患者的输尿管膀胱吻合术。
我们确定了输尿管支架在移植患者中的价值。在一个前瞻性随机系列研究中,对194例肾移植患者(97例使用双猪尾输尿管支架,97例未使用)的泌尿系统并发症(漏尿、梗阻和尿路感染)发生率进行了比较。
支架组有1例患者发生尿漏,35例发生尿路感染(包括2例棒状杆菌膀胱炎)。无支架组有6例患者发生尿漏,4例发生梗阻,32例发生尿路感染。两组患者1年的生存率和移植肾存活率相似,1年时的肾功能也相似(支架组和无支架组的肌酐水平分别为229和208μmol/l)。发生了少量与支架相关的并发症(2例支架断裂和1例支架移位)。所有病例均未形成结石。
输尿管支架置入术可显著降低肾移植中膀胱输尿管漏和梗阻的发生率。
