Percutaneous micro-channel approach in treatment of pelvis side cyst and ureteropelvic junction obstruction simultaneously / 中国内镜杂志

ABSTRACT

Objective To evaluate the efficacy and safety of percutaneous micro-channel approach in treatment of pelvis side cyst and ureteropelvic junction obstruction simultaneously. Methods 32 patients with unilateral solitary parapelvic cyst complicated with UPJO, including 25 cases with ipsilateral kidney stones. After percutaneous holmium laser lithotripsy for patients complicated with calculi, then performed incision and drainage through the channels for parapelvic cyst by holmium laser, and antegrade high pressure balloon dilatation for UPJO, drainage by hippocampal tube in 3 ~ 6 months postoperatively. The operation time of fenestration drainage of cyst, narrow hypertensive dilatation and postoperative hospital stay were analyzed. Results Compared with 1 month (46.17 ± 6.33), 3 months (40.47 ± 6.06), 6 months (33.81 ± 7.05), 9 months (28.95 ± 7.92) after surgery, there was a marked improvement of the separation coefficient of renal convergence, the difference was statistically significant (P < 0.05). And compared with 6 months after surgery, the data of 9 months after surgery has statistical significant differences (P < 0.05). The separation coefficient of renal convergence decreases as time goes on. Conclusions Percutaneous micro-channel approach in treatment of pelvis side cyst and ureteropelvic junction obstruction by the same time can effectively relieve symptoms and decrease the separation coefficient of renal convergence. It is safe and effective.
