Objective: To evaluate the impact of ureteral stent insertion following semirigid ureterorenoscopy (URS) in patients with perirenal fat stranding (PFS) due to ureteral stones.
Material and methods: Data of 600 patients who underwent URS were analyzed retrospectively. Seventy-two patients detected to have PFS accompanying ureteral stone were included. Patients who did not undergo double J (DJ) stent insertion following semirigid URS were classified as Group I (n: 52), while those who underwent stent insertion were classified as Group II (n: 20). Side distribution; localization of the stones, stone size, presence of fever, urinary tract infection (UTIs) and urosepsis rates were compared in the two groups.
Results: The average age of the patients was 44.4 (20-71) years. Male/female ratio and side of the stone location showed similar distribution in both groups (p > 0.05). Fever occurred in 23 cases (44.2%) in Group I and in 15 cases (75%) in Group II (p = 0.038). UTIs occurred in 15 cases (28.9%) in Group I and in 12 cases (60%) in Group II (p = 0.03). Urosepsis presented in 3 (5.8%) and 5 (25%) of the patients in Group I and II, respectively (p = 0.033).
Conclusions: According to our results, ureteral DJ stent insertion following URS in patients with PFS due to ureteral stone caused an increase on postoperative infection related complications.
