Input: Seven RCTs (1154 patients) of low or moderate quality were identified. The incidence of MUCs was significantly reduced (RR 0.24, 95% CI 0.07 to 0.77, P = 0.02, NNT 13) by universal prophylactic stenting. This was dependent on whether the same surgeon performed, or was in attendance, during the operations. Two patients lost their grafts to infective urinary tract complications in the stented group. UTIs, in general, were more common in stented patients (RR 1.49, 95% CI 1.04 to 2.15) unless the patients were prescribed cotrimoxazole 480 mg/d: in which case the incidence was equivalent (RR 0.97, 95% CI 0.71 to 1.33). Stents appeared generally well tolerated, although studies using longer stents (≥ 20 cm) for longer periods (> 6 weeks) had more problems with encrustation and migration. Routine prophylactic stenting reduces the incidence of MUCs. Studies comparing selective stenting and universal prophylactic stenting, whilst difficult to design and analyse, would address the unresolved quality of life and economic issues.
Output:

This review aimed to determine the benefit and harms of the use of routine stenting in kidney transplant recipients in the prevention of urological complications. Seven studies (1154 patients) were identified. The incidence of MUCs were significantly reduced by the use of prophylactic stenting. Urinary tract infections (UTIs) were more common in stented patients however the addition of antibiotic prophylaxis resulted in no difference in the incidence of UTIs between the two groups. More studies are needed to investigate the use of selective versus universal prophylactic stenting for the unresolved issues of quality of life and cost.
