To compare treatment-related outcomes of ureteral stenting with an external versus double J stent in patients with orthotopic reservoirs after radical cystectomy.


Patients undergoing radical cystectomy and orthotopic neobladder were randomized into two groups; group I patients received external stents, whereas group II received double J stents. In both groups, preoperative parameters were recorded, and patients were assessed regarding urinary tract infection, urinary leakage, upper tract deterioration, readmission and hospital stay.


A total of 48 and 45 patients were randomized in the external stent group and double J group, respectively. Both groups were comparable in terms of age, sex, associated comorbidity and oncological status. Early urinary leak was observed in two patients (4.2%) in the external stent group, and in two patients (4.4%) in the double J group (P = 0.95). None of our patients developed ureteral strictures in the external stent group, and one patient did in the double J group (P = 0.3). Positive urine culture (58.3%, 51.1%) as well as febrile urinary tract infections (2.1%, 6.7%) were comparable between both groups, respectively (P = 0.43, 0.28). Wound complications (12.5%, 8.9%) and stent-related complications (2.1%, 0%) were comparable between both groups, respectively (P = 0.57, 0.33). The mean hospital stay was 17.5 days (range 14-32 days) and 14.6 days (range 10-42 days) in both groups, respectively (P = 0.001), with comparable re-admission rates (P = 0.95).


Incorporation of double J stents in orthotopic urinary diversion is a safe alternative to the routinely used external stenting.
