ABSTRACT: Objective: To evaluate the outcome of ureteroscopic pneumatic lithotripsy in single lower ureteric calculus and correlate its success with different CT parameters like HU, size of calculus and hydrnephrosis, if present. Patients and Methods: This study was conducted from October 2017 to March 2019 in Department of General Surgery, Maulana Azad Medical College, New Delhi. 30 patients (out of which 6 were excluded due to spontaneous passage of calculus), with single lower ureteric calculus were chosen and the outcome of URSL was compared with respect to CT parameters of Size, HU and Hydronephrosis and intra-operative clearance of calculus. Results: Success rate of URSL in single lower ureteric calculus was found to be 75%. Lower HU (774.12 ± 212.85) was associated with higher success rate. Similarly smaller size of calculus (9 ± 2.1) mm was associated with success group. Patients with gross hydronephrosis had a poor outcome of URSL. Lower urinary tract infection (8.33%) was the most common complication. Conclusion: Patients with small size calculus, low HU and absence of hydronephrosis have a better outcome of URSL.
