Endovascular treatment of ureteral stenosis:a report of 628 cases / 局解手术学杂志

Objective To summarise and analyze the clinical effecacy of endovascular treatment(internal holmium laser incision,bal-loon dilation,ureter dilator,rigid ureter dilation)for ureteral stricture.Methods The clinical data of 628 patients from January 2010 to Jan-uary 2015 in our hospital were analyzed.The relevant operation indicators,postoperative complications and recovery condition were recorded and analyzed.Results The operation time was 5.5 to 29 minutes,with average time of 16.5 minutes,no ureteral avulsion,ureteral fragmen-tation and massive haemorrhage happened.All patients were followed up for 6 to 36 months,591 cases(94.1%)were cured,29 cases (4.6%)of postoperative stricture recurrence received endovascular treatment again,8 patients(1.3%)conversion to open ureterolithotomy. Conclusion Endovascular treatment of ureteral stricture is diversified within holmium laser incision,it has the advantages of shorter opera-tion time,fewer complications,less trauma,repeatability and so on,which is an effective and safe treatment method.

Curative observation of polyscope modular flexible ureteroscope combined with Holmium laser lithotripsy in the treatment of renal calculi / 局解手术学杂志

Objective To evaluate the curative effect of polyscope modular flexible ureteroscope combined with Holmium laser lithotrip-sy in the treatment of renal calculi. Methods 53 patients with renal calculi were performed CTU to detect the position of renal calculi before operation. The patients were treated with polyscope modular flexible ureteroscope combined with Holmium laser, and the double J tube were routinely indwelled 4 to 12 weeks after surgery. Results All the 52 patients has successfully completed the operation in the frist stage. The mean operative time was about 38 minutes. 6 patients were treated with flexible ureteroscope for second stage operation. One week after oper-ation, the review showed that there were residual calculi existed in 24 cases and there were 56 cases of post-operative infection, including 17 cases of sepsis or sepsis shock. Conclusion Polyscope modular flexible ureteroscope can be used for all kinds of kidney stones surgery and is characterized by safety and mild tissue injury. But we should pay more attention to the post-operative infection especially urosepsis.

Clinical efficacy of physical vibration lithecbole / 局解手术学杂志

Objective To analyze the clinical efficacy of physical vibration lithecbole in treatment of urinary calculi. Methods Ana-lysed the efficacy of 80 patients who underwent physical vibration lithecbole only or combination therapy with surgery in urinary calculi in our hospital from February 2014 to July 2014. Result There were 1 to 4 times calculi discharge among the 80 patients. One month after the sur-gery, the calculi discharge rate was 33. 3% and the calculi clean rate was 22. 2% in the upper ureteral; the calculi discharge rate was 16. 7%and the calculi clean rate was 50. 0% in the distal ureteral; the calculi discharge rate was 40. 0% and the calculi clean rate was 23. 3% in the upper renal calyx;the calculi discharge rate was 27. 7% and the calculi clean rate was 38. 8% in the middle renal calyx;the calculi discharge rate was 60. 0% and the calculi clean rate was 20. 0% in the lower renal calyx. One month after the surgery of physical vi-bration lithecbole combined with Holium laser lithotripsy, the calculi discharge rate was 52. 1% and the calculi clean rate was 39. 1%. Con-clusion Physical vibration lithecbole is a noninvasive treatment for urinary calculi. It has good efficacy in calculi discharge and it can relieve the pain caused by calculi.
