Use of gastric segment in urinary bladder replacement after total cystectomy

Drainage of urine by abnormal way is urinary derivation. Various forms of urinary derivations are available for urinary bladder replacement after radical cystectomy for invasive bladder tumor. Construction of continent urinary reservoir, so called pouch, from different bowel segments is named continent urinary derivations. If such urinary reservoir is connected with urethra, then it is about orthotopic derivation and reservoir is defined as neobladder. Upon satisfactory results of introduction of continent urinary derivations with Mainz pouch I and Orthotopic Mainz pouch, we performed continent orthotopic urine derivation with isolated gastric segment in 74-year old male patient who had previously undergone radical cystoprostatectomy because of the invasive urothelial cancer of the urinary bladder. Even though there were no major surgical complications in the near postoperative course, the patient had to be operated ten months later for ileus; 20 months after the procedure, significant loss of neobladder capacity, bilateral vesicoureteral reflux, persistent urinary infection and incipient renal failure were manifested. In the further course, reoperation was needed and neobladder augmentation by ileal pouch along with both ureteral reimplantations into the pouch wall was carried out. After this reintervention, the patient was alive in the following three years with satisfactory quality of life and preserved renal function. Our conclusion is that gastric neobladder should not be the first method of choice for urinary bladder replacement after radical cystectomy in older patients.
