Objectives:
This study aimed to present the outcomes of retrograde and antegrade ureteroscopic laser lithotripsy in the treatment of proximal ureteral stones ranging in size from 10 to 20 millimeters in diameter.
Patients And Methods:
From March 2023 to December 2023, 70 patients were included in this prospective randomized double-arm interventional study. Patients were divided into two groups: Group 1 (35 patients) had semi-rigid retrograde ureteroscopic laser lithotripsy, and Group 2 (35 patients) had semi-rigid antegrade ureteroscopic laser lithotripsy.
Results:
In terms of length of hospitalization, there was a statistically significant distinction between the groups that were evaluated (p = 0.001). Group (1) showed a statistically significant distinction in Hb and HCT levels before and after the procedure (p < 0.05), whereas Group (2) showed a similar difference in Hb, creatinine, and HCT levels before and after the operation (p < 0.05). The antegrade group had much more hemorrhage than the retrograde group. Reduced hemoglobin (p = 0.008) and hemoglobin saturation (p = 0.029) were most noticeable in the antegrade group. Regarding stone-free rates (SFRs), no statistically significant difference was noted between the groups (p = 0.643).
Conclusion:
Both retrograde and antegrade ureteroscopic laser lithotripsy are dependable and successful for the treatment of proximal ureteral stones. For medium-sized proximal ureteral stones (10-20 mm), retrograde ureteroscopic laser lithotripsy may be the first option due to its shorter hospital stays, decreased bleeding rates, blood transfusion needs, and temporary rise in serum creatinine.
