BACKGROUND: The role of ureteric stenting in kidney transplant recipients is still debatable. Stenting can reduce the incidence of urine leaks and ureter stenosis, but can be also associated with specific complications, particularly urinary tract infections (UTIs).
MATERIAL AND METHODS: To estimate the influence of ureteric stenting on urological complications in kidney transplantation (KTx), we retrospectively analyzed all KTx performed between January 2011 and December 2016 in Gdansk Transplantation Centre, a total of 628 patients. Ureteric stenting was used in 502 patients (80%)-double-J (DJ) group. Catheters were implanted during the surgical procedure and left in situ for a mean time of 30 days.
RESULT: The frequency of urinary leaks was 10 times higher in patients without stenting (10%). Ureter stenosis was also more frequent in the non-DJ group (8.7% vs 1.6%, P < .05). Multiple-regression modeling showed that the urinary not stenting was a risk factor for urinary leak (adjusted odds ratio [AOR] = 0,1; 95% confidence interval [CI]: 0.03-0.26; P < .01), ureter stenosis (AOR = 0,16; 95% CI: 0.06-0.41; P < .01), and generally reoperation after KTx (AOR = 0,46; 95% CI: 0.28-0.77; P < .01). Acute rejection and delayed graft function were equal in both groups. Mean serum creatinine concentration 1 month after transplantation was similar in both groups (1.5 mg/dL in the DJ group and 1.44 mg/dL in the non-DJ group, P > .05). UTIs were more frequent in the DJ group (22.1% vs 16.7%), but the difference was not significant. Time of hospitalization was longer in patients with UTI (34 vs 22 days, P < .05).
CONCLUSIONS: Ureteric stenting can protect patients from most frequent urological complications like urine leaks and ureter stenosis. The influence of ureteric stenting on UTI development is not strong in our material.
