OBJECTIVE: We investigated the characteristics of patients who underwent Double-J catheter (D-J) implantation, the risk factors for prolonged urine leakage (PUL), and prediction of patients who require medical treatment.
METHODS: The data of 535 adult patients who underwent PNL due to kidney stone disease between January 2005 and December 2011 in our clinic were analyzed retrospectively. Patients were divided into 2 groups: Group 1 (n=77) (14.39%) included patients with Double-J catheter due to prolonged (> 24 h) urinary leakage and Group 2 (n=458) (85.61%) patients without urinary leakage.
RESULTS: The mean stone burden was 951.94 ± 539.09 mm2 in Group 1, and 676.35 ±296.65 mm2 in Group 2 (p< 0.05). DJ catheter was implanted in 11.33% of the patients with stone burden below 1000 mm2 versus in 51.21% of the patients with stone burden above 1000 mm2. In Group 1, the number of patients with two or more accesses performed was 18.18, whereas in Group 2 it was 8.5% (p< 0.05). Among all patients, DJ implantation was performed in 13.07% of patients with a single access versus 26.41% of patients with two or more accesses. Also, DJ catheter was implanted in 41.46%of patients with residual stones versus 12.14% of stone-free patients. Three patients with stone burden above 1000 mm2, two or more accesses, and residual stone, all of them required DJ implantation.
CONCLUSION: DJ implantation due to PUL had approximately 5-fold increase stone burden above 1000 mm2, 2-fold increase in patients undergoing two or more access and 3-fold increase in patients with residual stones. Therefore, we think that the D-J implantation is highly advisable in case of a stone load above 1000 mm2, two or more accesses, and in patients with residual stones.
