#3616 NON-ANESTHETIC STENTING IS AN EQUIVALENTLY EFFECTIVE METHOD COMPARED WITH PERCUTANEOUS NEPHROSTOMY IN ACHIEVING EARLY RECOVERY IN STONE INFECTED PATIENTS

Abstract

Abstract Background and Aims The prevalence of urinary tract stones is increasing. Although the importance of urgent decompression in managing this condition is well established, preferences for drainage methods (stenting vs. percutaneous nephrostomy [PCN]) differ depending on the treating institution. We therefore analyzed the effects of different drainage methods on early recovery. Method We retrospectively reviewed the medical records of patients hospitalized for infection with urinary obstruction due to urinary calculi at Gangneung Asan Hospital between January 2011 and December 2020. All patients underwent stenting or PCN. Early recovery was defined as subsided fever or discharge within 3 days after the procedure. Results A total of 178 patients, including 98 treated with double J stents and 80 treated with PCN were included. Univariate analysis revealed male sex, diabetes mellitus, coronary heart disease, mid ureter stone, upper ureter stone, stone size of 10-20 mm, and renal stone concomitance as significant prognostic factors for early recovery. In contrast, multivariate analysis revealed male sex (P=0.036), diabetes mellitus (P=0.031), mid ureter stone (P=0.007), upper ureter stone (P=0.026) as significant prognostic factors for early recovery (Table 2). When stenting was compared with PCN, the recovery period of fever and C-reactive protein and white blood cell levels showed similar trends. Conclusion Male patients and those without risk factors for stone-related complications tended to recover more easily after the procedure. The results demonstrate that non-anesthetic stenting is an effective method, compared with PCN, to achieve early recovery in infected patients due to stone obstruction.
