ABSTRACT
The records of 87 children with bladder exstrophy seen between 1912 and 1935 are reviewed. We believe that ureterosigmoidostomy with cystectomy can provide a satisfactory solution to the problem of bladder exstrophy. Furthermore, ureterosigmoidostomy appears suitable from the standpoint of preservation of upper tracts and provides a socially acceptable solution to the question of disposal of the diverted urine. The best treatment for exstrophy of the bladder remains a subject of debate. Although primary closure of the bladder would seem to be the ideal solution, efforts in this direction have been frustrated by reflux, ascending pyelonephritis, dehiscence of the anterior closure and complete urinary incontinence in the majority of patients. 1 Others have thought that cystectomy followed by urinary diversion yields a more satisfactory result in terms of preserved upper tracts and creation of a socially acceptable individual. 2 • 4 The ideal form of urinary diversion has yet to .be devised but Spence presented a good case for the use of ureterosigmoidostomy as the preferred method of diversion in children with bladder exstrophy. 5 We thought that a review of the long-term results in patients treated in this manner many years ago might assist us in assessing the usefulness of ureterosigmoidostomy.
urethral twist, for reasons that are not clear in the record. The right ureteral colonic anastomosis was performed first. The left anastomosis was performed 7 to 10 days later and 10 days after that cystectomy was done. The Coffey I technique was used in all of these cases.• The mean age of patients at the time of operation was 5.6 years. Hospital mortality for those undergoing ureterosigmoidostomy with or without cystectomy was 10 per cent and mostly caused by uncontrollable infection. Of these patients 3 were lost to followup, leaving 51 children who underwent bilateral ureterosigmoidostomy with or without cystectomy as the basis for this report. Followup information on this group was obtained by correspondence with patients and their physicians as well as by evaluation at the Mayo Clinic.

years postoperatively. Of these patients 8 have survived 45 years or longer and, with 3 of the deceased patients previously mentioned, 11 have ' survived 45 years or longer (table 3). However, their urinary tracts have suffered. In half, the left kidneys either have been removed or are not functioning. The right sides have fared better, " although 1 patient required a nephrostomy. Of the 3 deaths, 2 were from non-renal causes. The patient who died of carcinoma of the colon had a normal excretory urogram (IVP) shortly before his death. Electrolyte values were normal in 2 of this group and 1 had slight hyperchloremic acidosis. A huge urinary calculus had formed in the rectum of 1 patient. .

and ureter could no longer be positioned in an ideal relationship. Also, urine is known to pool in the loop between the 2 anastomoses, and reflux of this infected urine and feces may have been a factor in the much greater renal morbidity found on the left side compared to the right side. Perhaps the most important cause of failure was the use of the Coffey technique of ureterointestinal anastomosis. This technique has long been known to produce the problems that characterize the history of this group-scarring with obstruction and reflux of contaminated matter. Much better results have been achieved by the combined technique of Leadbetter: two-thirds of Spence's pediatric patients in whom this anastomosis was used had normal upper tracts. 5 We are not attempting to ignore the problems attendant on ureterosigmoidostomy. It is obvious that only a few of these patients have lived their lives without significant sequelae directly related to the fact that ureterosigmoidostomy was done. However, we do think that many of these problems would have been avoidable had the surgeons used the combined technique, in a single-stage procedure, with the other adjunctive measures and knowledge now available. The other major consideration in this group is social adjustment of these patients. It is agreed that anything is better than the untreated exstrophy. The constant exposure of urine produces a social pariah and, as time passes, the threat of adenocarcinoma of the bladder becomes more and more real. Few of the 17 patients who died early of renal causes could be said to have done well. Relieved of the burden of their bladders they spent their average of 15 years of life suffering the symptoms of pyelonephritis and then died of uremia. If it is true that the majority of untreated TABLE

COMMENT
It seems apparent that ureterosigmoidostomy in these circumstances has the capacity to carry the patient over the long haul and has done so in 25 per 'i cent of those who survived the operation. Why did it not do so in more children and, particularly, why did a third of the group die of renal causes at an ,1. average of 15 years postoperatively? The following considerations may answer these questions. No antibiotics or effective urinary antiseptics were available at the time of these operations. The hyperchloremic acidosis and other electrolyte changes that occur as sequelae to this operation were unknown. Initial followup was inadequate by . present standards, although one wonders what ·' more could have been done, in that era, for these children. Anastomosis was always done first on the right side. One suspects that its location and -, orientation were ideal and that the left anastomosis then was placed wherever it seemed possible, in a previously operated upon field where the sigmoid

patients die by the age of 21 of ascending pyelonephritis, then little has been lost in this group. 7 However, examination of the lives of the surviving patients reveals what appears to be a satisfactory quality of life. The women have married and have had children; 1 woman had 6 children. Two patients are attorneys, 1 is a rancher and all have made their way in the world including a 58-yearold man who, when last heard from 55 years postoperatively, was traveling around the Pacific Ocean on a freighter.
