20 Years of Functional Reconstructive Surgery in Bladder Exstrophy - Balance 10 Years After a Preliminary Report P. acher, M. chwöbel, U. G. Stauffir Depaltmenl of Surgery, eniversily Children 's Hospital, Zurich, Swilzerland

This is an update of a consecutive series of 19 patients with bladder exstrophy presented as a preliminary report 10 years aga with a follow-up of 6 years. The average time of follow-up now is 14 years. In difference to the former reporl everal additional procedures have been performed in most patients. 3 earl)" "good" patients stay "good and continent".

The overall rate of secondary di\'ersions is 40 % including 2 patients \\ith ureteroigmoidostomies. All patients have normal renal function and normal blood pressures. These results show that an early "good" result generally remains "good" but additional surgery may be warranted. The initially "fair" results usually necessitate a secondary procedure, e. g. augmentation cystoplasty or/and bladder neck tightening to show an improvement. Patients with early "poor" results unfortunately remain "poor" and have a great chance to get diverted.

Es werden 19 Patienten, bei denen wegen einer Ekstrophie eine Blasenrekonstruktion durchgeführt worden war, 10 Jahre nach einer ersten Bestandsaufnahme mit einer mittleren Nachbeobachtungszeit von 6 Jahren nochmals vorgestellt. Die durchschnittliche Nachbeobachtungszeit beträgt nun im Durchschnitt 14 Jahre. Bei der Mehrzahl der Patienten wurden seit dem letzten Bericht weitere Eingriffe durchgeführt. 3 initial "gute" Fälle sind weiterhin "gut und kontinent". ur 3 von 5 Patienten, die vor 10 Jahren als "genügend" beurteilt wurden, sind nun "gut und kontinent", nur einer davon ohne weitere Eingriffe. 3 von 6 Patienten mit einern primär "ungenügenden" Resultat haben nun eine Umleitungsoperation. Die Rate von sekundären Umleitungen beträgt 40 %, mit eingeschlossen 2 Patienten mit einer Ureterosigmoidostomie, Alle Patienten haben eine normale ierenfunktion und einen normalen Blutdruck. Die Resultate dieser kleinen konsekutiven Serie zeigen, daß ein initial gutes Resultat meistens gut bleibt. Die Patienten mit initial genügendem Resultat benötigen in den meisten Fällen weitere Eingriffe, wie eine Augmentationszystoplastik und! oder eine Kontinenzplastik, um sich zu verbessern. Diejenigen Patienten mit einern initial ungenügenden Resultat bleiben leider häufig ungenügend. Bei den meisten dieser Patienten muß das initiale Management der Blasenrekonstruktionschirurgie verlassen und eine sekundäre Umleitungsoperation vorgenommen werden.

low-pressure reservoir and attalnment of a satisfactory cosmetic and functional phallu in boys (6).

Inlroduction This report deals wiLh lhe ame series of 19 patients wiLh bladder exstrophy that were presented 10 years ago (11). The aim of this article is to elucidate the evolution of each case untiJ puberty, i. e. definite correction of Lhe malformation, and to asse s whether a follow-up of 6 years chosen for Lhe first report in 1982 is safe enough or not.

We were especially interested to ee Lhe individual evolution of every patient since the last report. With one exception, all patients have now reached or passed puberty.

Results .\talerials and meLhods Our series of 19 patients includes 15 boys and -I girls. All 19 patients had slaged funcLional c10sure of bladder exstrophy, no primary urinary diversion was undeltaken. Ages at bladder c10sure ranged from 10 days to 6 Ih years. Reconstruction consisted of a staged proced ure: (I) posLerior peh'ie osteotomy according to Schultz, (2) Turn-in-operation simultaneously wiLh bladder neck reconsLruction and a ureteral reimplant mostly by Politano-Leadbeller technique and (3) eloure of epi padias if necessary eombined with a ) ollllg-DeesLeadbeller bladder neck tightening. In 1981 Lhe resuJts were categorized as "good", "fair" or "POOl''' (li). PaLients in whom time elapse since turnin-operation \\'as less than 3 real' \\'ere not been da sified. Criteria for a "good ,. result \\'ere normal renal function, no signs of obstructive uropathy, no recurrent urinary infections and a urinary continence of at least 2 hours. Actual data and radiographs or ultrasound examinations of all patients ha\'e been collected and analyzed. A questionnaire has been sent to those patients who are not treated at our institution any longer. Patients Lhat were suitable for analysi have been classified as "good/continent", "diverted" or "incontinent". Nowadays criteria of a "good/continent" result consist of preservation of renal function, creation of a continent

11 out of all 19 patients are till treated at OUf institution. Sinee our last report foul' patients ha\'e been operated on at other institutions. Three patients living in foreign countries were lost for follow-up. Therefore Lhe results of 16 patients are presented. The a\'erage time of follow-up i no\\' 14 (min. 10, max. 18) years. 6 out of 16 patients (38 %), --l boy and 2 girls, may be categorized as "good/continent" according to Lhe above mentioned criteria of HlISlllan et al (6).

Six patients haw an external or internal urinary diversion. Foul' of them ha\'e a continent diversion i. e. twiee a ureterosigmoidostomy and a MitrofanojJ'bladder and a .\1ainz pouch one eaeh. In one patient the eutaneou ureterostomie ha\'e not yet been taken down and in another one construction of a cutaneous ureterostomy has been necessary due to obstructive uropathy in a single kidney. Three patients are till incontinent. OnJy one of them is treated aL OUf institution any longer. A recently performed augmentationcystopla ty did not alter urinary incontinence ignificantly. A bladder neck tightening is planned. None of our patients has lost a kidney. All 16 patients have normal renal function and normal blood pressures. The clinicaJ and laboratory data at present follow-up are summarized in Table 2.

out further inten'ention, one with an additional augmentation cystopla ty and one with augmentation cy toplasty combined with a secondary bladder neck tightening. Three out of 6 patients who \-\'ere c1assified as "poor" are divelted. One has a ureterosigmoidostomy, one a 1\1ainz pouch and one has still cutaneous ureterostomies. Two of the formerly unclassified cases are now diverted. One has a Mitrofanoffbladder and the other one a cutaneous ureterostomy resulting in an overall rate of 40 % of secondary diversions. Since our last report an augmentation cystoplasty has been performed in 4 boys. 5 boys underwent orthoplasty of the penis according to Ransley and Kramer. A vaginoplasty has been performed in two girls,

Discussion 10 years ago we stated that the ideal result of recon tructive urgery in children \\ith bladder ex trophy would be a child with total urinary continence, free of recurrent urinary tract infections, normal kidneys and normal renal function, . owadays the goals of treatment - presen'ation of renal function and creation of a continent low-pressure resen'oir are upplemented \\'ith attainment of a satisfactory cosmetic and functional phallus in boy (6), -

E\'en in the light of these criteria 6 out of 16 patients (38 %) show a "good/continent" result. This lies in between the 25 % of the BAPS re\'ie\\' b\' de lu IIlI/zt et al (3) and the 86 % reported by Oesterling andJ;jJs (10). According to our consecutive series of 19 patients with bladder exstrophy, the time of bladder c10sure seems

279

not to be of importance for a succes ful outcome since onJy one ofthe 6 "good/continent" patients ha been operated on as a neonate. All the other 5 children were older than one year when the turn-in-operation was undertaken. One girl was even 6 1/2 year old, This is in contra t to the statement of Montagnani (9) that a prolonged exposure of the exstrophied bladder to mechanical irritation and infection wouJd be a main factar for unsuccessful outcome, . evertheless most authors including our group tend today towards closure of the bladder during the first 48 hours of life, the main reason being that pehic osteotomy may not be necessary and bladder closure is much easier, In the present series an early diversion, i. e, cutaneous ureterostomy, has been necessary in two cases, probably due lo an obstructive uropathy following a primary ureteral reimplantation in a thickened bladder wall simultaneously with the turn-in-operation, Therefore, primary reimplantation is no Ionger performed at our institution, The ureters are only reimplanted no\-\' at the time of the Young-Dees-Leadbetterprocedure (8, 10). Reconstructi\'e surgery has an imminent risk for an obstructi\'e uropathy and consequent renal damage and insufficiency, A few centers therefore still favour primary urinary diwrsion, e. g. a ureterosigmoidostomy as a beller solution for the problem, One reason for thi management is the fact thatthe upper urinal)' tract is primar')' normal, i. e. there is no hydronephrosis or ureteral dilatation. Fröhneberg et aI (4) demonstrated in a review of 38 patients that after a ureterosigmoidostomy no deterioration is to be expected prO\ided that the upper urinal')' tract is preoperati\'ely normal. Howe\'er, Husmann et aI (6) shO\\'ed that in patients managed \\ith a uri-' nary diversion the occurrence of renal damage was notably higher even with antireflux techniques. This is in agreement with Mollard (8) who states that in long-term view the risks of reconstructive surgery for the kidneys eems to be minor compared to internal and external diver ions. One major problem that has been argued again t ureterosigmoidostomy is the possibility of neoplastic complications (6, 7, 12), Therefore many authars believe that ureterosigmoidostomy is no more an acceptable means of urinary diversion. However, there are recent reports about carcinoma arising after ileocystoplasty (5) and indeed "it is not unreasonable to believe that the incidence of cancer in augmented bladder may not be appreciably different from that seen in ureterosigmoidostomy" as Allen (1) states in an Editorial Comment in the Journal of Urology in 1989. In the light of these facts we believe that ureterosigmoidostomy is still an alternative for a limited number of patients \\ith bladder exstrophy, especially when taking into consideration the necessity of the patient's compliance to intermillent catheterization, the possibility of the bladder needing augmentation and the p ychological impact of wet tomata. \\'e think that the individual history of a patient after reconstruction is of special interest and imporlance, .'.lost reports, ho\\'e\'er, deal \\'ith "numbers and percentages". Our indi\'idual re ults ho\\ that an early "good" re ult gene rally remains "good". The initially "fair" results usually necessitate a secondary procedure, e. g. augmentation cy toplasty and/or bladder neck tightening, to show an im-

provement. Patients with early "poor" results remain unfortunately poor and have a great chance to get diverted. Girl have a rar better chance for a successful reconstruction of bladder exstrophy than boys. In more than half of the boys in oUf eries reconstructive surgery had to be abandoned. Ideally, the reconstruction of the bladder should be achieved at the age of school entrance.
