Unlabelled:
The Department of Urology in Lund, Sweden, has a long association with innovations in reconstructive urology. The authors from that department describe their experience over a long period with orthotopic bladder substitution and continent cutaneous urinary diversion. They conclude that continent urinary tract reconstruction is associated with a high incidence of early and late complications. They also found that for storage and emptying, their Lundiana pouch was superior to the Goldwasser neobladder.
Objective:
To assess the early and late complications and functional results in patients undergoing continent reconstruction of the urinary tract, i.e. orthotopic bladder substitution (OBS) or continent cutaneous diversion (CCD).
Patients And Methods:
The medical records of all patients undergoing OBS (Goldwasser technique) or CCD ('Lundiana' technique) for malignant or benign disease during 1987-1999 and followed to December 2001 were reviewed. There were 67 patients with neobladders, 77 with a Lundiana pouch who had undergone radical cystectomy and 22 with a Lundiana pouch operated for benign disorders.
Results:
Early complications requiring reoperation occurred in 12% of the cystectomy group, with no difference with type of reconstruction, and in 10% with benign diseases. Four patients (3%) undergoing radical cystectomy died from early cardiovascular complications, two after surgery for intra-abdominal complications. Intestinally related complications and wound dehiscence requiring re-operation occurred in nine and six patients, respectively. The incidence of late complications requiring open surgery was 22% and 23% after cystectomy with OBS and CCD, respectively. The value in patients with benign diseases undergoing CCD was also 23%. Stone formation in the pouch was common, occurring in 12% in patients with OBS and in 10% after CCD. The pouch perforated or ruptured in four patients. The incidence of uretero-intestinal stricture using the Le Duc technique was 2.4% and renal function was well preserved. The incidence of revisional surgery of the Lundiana pouch outlet for incontinence was low and all patients but four were continent. The functional outcome in patients with OBS was less good; some needed pouch augmentation or an artificial urinary sphincter. Most patients used incontinence products and many needed clean intermittent self-catheterization.
Conclusion:
Continent urinary tract reconstruction is associated with a high incidence of early and late complications. For storage and emptying, the CCD Lundiana pouch is superior to the OBS of Goldwasser.
