Abstract:
Objective To explore the technique of implantation of double-J stent via the guide-wire track, which was established through percutaneous renal puncturing, for the treatment of ureteral stricture and obstruction, and to evaluate its therapeutic effect. Methods A total of 75 patients with ureteral stricture or obstruction, who failed to respond to cystoscopic catheterization, were enrolled in this study. The lesions included benign stricture(n=60) and malignant stricture(n=15). Ureteral guide-wire track was established through percutaneous renal puncturing, which was followed by the dilatation of the stricture with balloon catheter and subsequent implantation of double-J stent via the guide-wire track. After the double-J stent was removed, the patients were followed up for 3 months to five years. Results The success rate of the procedure was 98.7%(74/75). Technical failure occurred in one patient with benign ureteral stricture. The cure rate was 70.7%(53/75), the improvement rate was 26.7%(20/75), and no improvement was seen in one case (1.35%). The total effective rate was 97.3%(73/75). Conclusion For the treatment of ureteral stricture and obstruction, the implantation of double-J stent via the guide-wire track, which is established through percutaneous renal puncturing, is a safe and effective method.
