Ureteral stones account for 20% of urolithiasis, with about 70% of them distally located.Renal colic secondary to obstructing ureteral calculi accounts for approximately 1% of all emergency department visits and hospital admissions.Regarding the success rates of URS, the American Urological Association ureteral stones guidelines panel summary report found a stone-free rate of 56% for stones of ＜1 cm and a stone-free rate of 44% for stones of ＞1 cm in the proximal ureter as compared with rates of 89% and 73% for stones in the distal ureter, respectively.The objective of this study was to assess the efficacy and safety of emergency ureteroscopic lithotripsy in patients with ureteral stones.

This descriptive study was conducted in the department of Urology from 1st February,2023 to March,2024 after attaining ethical approval from Institutional review board.All 144 patients with Ureteral stone presenting to Urology emergency or OPD after taking detail history, examination and stone confirming by CT KUB, admitted to urology department and underwent URS using 6/7.5 fr Ureteroscope and pneumatic Swiss Lithoclast followed by insertion of 6Fr DJ stent. Patients were discharged on the next post-op day. Called for follow up and DJ stent removed after confirming stone free status after 2 weeks. Patients having active urinary tract infection, sepsis, stone size >1.5 cm and patients with any anatomical or physiological abnormalities were excluded from our study.

This study was conducted on 144 patients. Mean age of the patients was 45.21±15.45 years. Mean size of stone was 0.89±0.24cm. out of 144 patients 80(55.6%) were male and 64(44.4%) were female patient . Regarding laterality, right side was involved in 84(58.3%) while left side was involved in 60 (41.7%) patients. stones were located proximally in 41(28.5%), mid part in 25(17.4%) and distally in 78 (54.2%) cases. Blood loss was observed in 1(1.5%) patients,sepsis 9 (6.2%), and ureteric injury in 5 (3.5%). The efficacy in terms of complete stone clearance was effective in 124 (88.2%).

Emergency URS is effective and safe and well tolerated procedure. We have observed excellent results however Randomized Controle Trial is needed to further endorsed our results.
