Background:
We present the results of patients submitted to a Studer type urinary orthotopic derivation after radical cystectomy.
Methods:
The files of patients with bladder cancer submitted to a radical cystectomy plus the procedure of the ileal neobladder were reviewed in our hospital from January 1992 until December 2004. Patients were divided into two groups: group A--60 years old or younger and group B-->60 years old.
Results:
From 306 patients submitted to radical cystectomy with urinary derivation, there were 42 patients (13.7%) included with Studer type neobladder. There were 34 (80.9 %) men and 8 (19.1%) women, with an average age of 60 years. Average surgical time was 7 h with an average blood loss of 1600 cc requiring transfer to intensive care unit (ICU) in 55% of the cases. The most frequent early complication was metabolic acidosis that was present in 28 (66%) patients. The most severe complication was ileal-ureter urinary leak, which was present in seven (16.6 %) patients. Among the most frequent late complications are the day- and night-time urinary incontinence often related to urinary infections and intestinal occlusion. Overall 5-year survival was 71%, cancer-specific mortality was 15% and surgical-related mortality was 7.3%.
Conclusions:
The performance of procedures with orthotopic neobladders is actually feasible in experienced hospital centers and is a valuable alternative to urinary heterotopic derivation with ileal conduit. Postoperative patient management and regular follow-up is of major importance.

Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
