Outcome of ureteroscopy for the management of distal ureteric calculi: 5-years’ experience

Abstract

Objective: To review our 5 years' experience with ureteroscopy treatment of distal ureteric calculi. Patients and methods: We reviewed the medical records of 136 patients who underwent ureteroscopic procedures for the treatment of distal ureteric calculi from February 2007 to October 2012. Patient and stone characteristics, treatment modality and outcome were assessed. Procedure's duration, status "stone free" and hospital stay were also evaluated. The mean clinical and radiological follow-up period was 31.8 months for 74.2% of eligible patients. Results: The stone free rate following an initial ureteroscopy was 79.4. The ultimate success rate for stone removal after "second look" improved to 95.9%. The mean operative duration was 51 minutes. The intraoperative complication rate was 8.6%, the postoperative complication rate was 7.5%, and the mean hospital stay was 1.1 days. We could detect one ureteric stricture and one vesico-ureteric reflux (0.9% for each). A significant ureteric perforation was detected in 4.1% and ureteric perforation in 0.7% of the study group. We could find that the longer the operative duration, the greater the complications. Stone impaction and size were also found associated with higher morbidity. Conclusion: Growing skills and experience of ureteroscopy will lead to a significant increase in the success rate and also reducing serious complications.

Ureteroscopy for management of ureteric calculi: Five years experience in Erbil, Iraq

“…16 In Weimin Yu, Fan Cheng et al 2014 retrograde ureteroscopic treatment for upper ureteral stones: A 5-Year Retrospective Study Overall, the stone-free rate was 90.4%, the mean operative duration was 41.2 ± 10.7 minutes, in our study the overall success rate was 93.7% and mean operative time was 26.1 minutes. 17 Ureteral stenting following uncomplicated URS is optional: several randomized prospective studies published since the 1997 AUA guideline document has demonstrated that routine stenting after uncomplicated URS may not be necessary.…”

Single centre study of stone clearance with ureterorenoscope & lithoclast for ureteric calculi; our experience.

“…The choice of management depends on the stone's site and characteristics, preference of patient and associated cost. 8 These techniques include ureteroscopy 9 , extracorporeal shockwave lithotripsy (ESWL) and laparoscopic ureterolithotomy. 8,10,11 Among them ureterorenoscope 9 by using Lithoclast is one of the leading management solution for the removal of ureteric stone removal.…”

Preoperative Th1/Th2 and related cytokines: Prediction value in postoperative febrile UTI after ureteroscopy in patients with ureteral calculi

“…3 With the advancement of ureteroscopic technologies, treatments for the removal of ureteral calculi have shown decreased procedural invasiveness with high success rates and limited morbidity. 4 In their paper, de la Rosette et al analyzed 11,885 ureteral calculi patients treated with ureteroscopy and revealed that the stone-free rate and postoperative complication rate were 85.6% and 3.5%, respectively, 5 suggesting that ureteroscopy can be used in patients with larger and more complicated stones, as well as elderly patients with significant comorbidities. 4 However, the incidence of severe complications is still high after ureteroscopy treatment, including febrile urinary tract infection (UTI).…”

Therefore, it is urgent to explore factors that may affect the postoperative occurrence of febrile UTI to provide a new therapeutic target for the treatment of ureteral calculi.…”
