How to avoid clean intermittent catheterization in men with ileal bladder substitution

In male patients with ileal bladder substitute we ascertained the likelihood of spontaneous voiding failure, the corrective procedures required and the eventual outcomes.

Following cystectomy and ileal bladder substitution for urothelial cancer between April 1985 and September 2002 male patients were identified and analyzed from the prospective departmental database. Four patients underwent ileum conduit conversion following urethral recurrence or pouch necrosis and were excluded from study. Funnel-shaped outlets were avoided during bladder substitute surgery after the first 4 patients with this configuration experienced voiding failure and required corrective procedures. Only patients with a minimum 5-year followup were assessed for voiding failure, corrective procedures and final outcomes.

Of 354 patients with a median age of 65 years (range 36 to 84) treated with bladder substitute 180 (51%) were alive at 5 years. All 180 of these patients spontaneously voided within 3 months of surgery. During this 5-year observation period 22 (12%) patients experienced voiding problems requiring de-obstructive procedures. Following intervention 177 (98%) patients were spontaneously voiding by 5 years. Of 237 patients 77 (32%) were alive at 10 years. Of these 77 patients followed for another 5 years 10 (13%) had similar voiding problems requiring de-obstructive procedures. Subsequently 74 (96%) were voiding spontaneously by 10 years.

Patients often fail to void spontaneously after ileal bladder substitution. However, if a funnel-shaped outlet is avoided and de-obstructive surgery is appropriately implemented, excellent long-term results are seen with spontaneous voiding and clean intermittent catheterization can be avoided.
