Objective To evaluate functional outcomes of continent cutaneous urinary diversion ( CCUD ) after radical cystectomy ( RC ) and to compare diversion‐related complications and long‐term renal function in a contemporary cohort of patients undergoing urinary diversion with CCUD , orthotopic bladder substitute ( OBS ) and ileal conduit ( IC ). Patients and Methods In all, 322 patients underwent RC and CCUD , OBS or IC from J anuary 2002 to J une 2013. CCUD was performed using either a modified Indiana pouch or an appendiceal stoma. For patients with CCUD , continence status and time intervals between clean intermittent catheterisations at last follow‐up were recorded. For all three diversion types, diversion‐related complications and renal function outcome, as determined by the estimated glomerular filtration rate ( eGFR ) at baseline and at different time intervals after surgery, were evaluated. Multivariate regression analysis was used to evaluate the association of diversion type, baseline variables and diversion‐related complications with renal function over time. Results Of all 322 patients, 73 (23%) received a CCUD , 79 (25%) received an OBS , and 170 (53%) received an IC . After a median follow‐up of 36 months, the continence rate for patients with a CCUD was 89%. In all, 64 (88%) patients with a CCUD were able to catheterise every 4–8 h and five (7%) were able to catheterise every 8–10 h. After a median follow‐up of 35 months, rates of diversion‐related complications were similar among patients who underwent a CCUD , an OBS or an IC . Patients who received an IC had poorer renal function preoperatively than those who received a CCUD or an OBS . However, at 1 year after surgery and thereafter, the three groups had comparable renal function. On multivariate analysis, the type of urinary diversion was not associated with decline in renal function. However, patient age at surgery, diabetes mellitus, baseline eGFR , postoperative non‐obstructive hydronephrosis and uretero‐enteric stricture were associated with decline in renal function. Conclusions A CCUD is associated with excellent functional outcomes. The rates of diversion‐related complications and renal function outcomes are comparable with those from an OBS and an IC . A CCUD should be considered a valid alternative for patients who undergo cystectomy and require urinary diversion.
