Abstract: BACKGROUND: To evaluate the surgical technique and functional outcome of a new application of the chimney modification to the popular Hautmann ileal neobladder. This modification used 3-5 cm chimney tubularized ileal segment for the bilateral ureterointestinal anastomosis. METHODS: Between December 2000 and July 2004, 15 patients (14 men, 1 woman) with invasive bladder cancer underwent radical cystectomy and Hautmann neobladder with chimney modification at Siriraj Hospital, Bangkok. Mean age was 61.7 years (range, 43-72 years). Perioperative morbidity, early and late urinary diversion-related complications, other surgical complications, follow-up results of ureterointestinal anastomosis, renal function and metabolic disorders were evaluated. Patients were interviewed about their continence, voiding function and potency. RESULTS: At a mean follow-up of 29.5 months, two patients had died of cancer progression. Of the 15 patients, nine (60%) had 10 early complications. Eight complications were related to the neobladder and two were not. Three (20%) patients had three late complications. Two complications were neobladder-related and one was not. There was no perioperative mortality. There was no ureteroileal anastomosis stricture in this series. Neobladder-ureteral reflux was demonstrated in eight of 22 ureteral units in 11 patients in whom cystography was performed. All patients had normal upper urinary tract without evidence of urinary obstruction. All 14 men (93% of study sample) had spontaneous urination, normal renal function and no metabolic acidosis. Good and satisfactory continence in the day and night were 93% and 73%, respectively. All male patients experienced impotence postoperatively. Only one sought treatment and was successfully treated with sildenafil. The one woman in this study required intermittent catheterization to empty the neobladder completely. She also had renal insufficiency with serum creatinine of 2.2 mg/dL and hyperchloraemic metabolic acidosis. CONCLUSION: New chimney modification in Hautmann ileal neobladder is simple and safe. Complications are acceptable. Follow-up results of renal and voiding functions are satisfactory. This operation can maintain good quality of life for patients with bladder cancer undergoing radical cystectomy. © 2006 Elsevier. All rights reserved.
