Stenting versus non-stenting before extracorporeal shock wave lithotripsy for proximal ureteric stones: A prospective interventional study

Abstract

Background: Extracorporeal shock wave lithotripsy (ESWL) has become the first-line treatment for stones in the upper urinary tract measuring 0.05).There was no significant difference between the two groups in regard to clearance according to the size of the stones. A total of 9.3%(28/300) of patients did not have a successful outcome and were termed as ESWL failures. Post- ESWL complications were significant between the both groups in terms of hematuria and ureteric colic. All the ureteric colic patients had a stone size larger than 13 mm, P=0.0005, which was more in the non-stented (Group B) patients. Most of the lower urinary tract symptoms were seen in stented (Group A) patients, P<0.0001 significant between the two groups, and dysuria was also significant between the two groups with P=0.0033. Conclusion: Pre-ESWL ureteral stenting provides no additional benefit over no stent in situ, although ureteral stents are associated with more irritative symptoms.
