Abstract

Between 1968 and 1978, 35 patients with complete exstrophy of the bladder have been treated. In 31 cases reconstruction was attempted using a 3-step procedure. First, the bladder was closed with a posterior iliac osteotomy and in the male patient the penis was lengthened. Next, an antireflux procedure and bladder neck reconstruction were done. The modification of the Young-Dees procedure was used, which allowed reconstruction of the vesicourethral angle as well as creation of an anterior muscular loop. Finally, the anterior epispadias was repaired. Of 16 patients who completed surgical treatment more than 1 year ago 6 female and 5 male subjects are cured, that is continent with a normal excretory urogram and no reflex. One male patient is improving and 4 boys are failures. The operative technique, postoperative training, results and selection of patients for functional closure are discussed.

Urethral obstruction after primary exstrophy closure: what is the fate of the genitourinary tract?

PURPOSE: We assessed the impact of posterior urethral obstruction after primary bladder exstrophy closure. MATERIALS AND METHODS: A review of the records of patients with classic bladder exstrophy at our institution identified 29 boys and 12 girls with a mean age of 11.75 years who had had posterior urethral outlet obstruction after closure was done in the neonatal period. RESULTS: Of these 41 patients 75% underwent closure elsewhere. At closure osteotomies were done in 13 patients and 23 were younger than 72 hours. Paraexstrophy skin flaps were used at primary closure in 27 cases (66%). Obstruction presented as recurrent urinary tract infection, upper tract deterioration with or without renal failure, bladder stones, difficult catheterization, urethral stitch erosion, a full bladder on ultrasound, a prolonged dry interval, urinary retention, inability to catheterize, bladder rupture, rectal prolapse and epididymitis or prostatitis. Usually the initial obstructive episode developed within 60 days of closure and it was recurrent. Therapy included suprapubic catheter placement, vesicostomy, ureterostomy, nephrostomy and multiple urethral manipulations, such as dilation with or without steroid injection, internal urethrotomy, urethral stitch removal, clean intermittent catheterization or open urethroplasty. All 6 patients who underwent long-term diversion via vesicostomy, ureterostomy or a conduit for greater than 6 months required permanent bowel segments for reconstruction, while in 5 of the 6 who underwent short-term diversion via nephrostomy or suprapubic tube placement for less than 6 months reconstruction was bowel-free. Of the 36 children in whom functional reconstruction was performed 9 are undergoing staged reconstruction, reconstruction failed in 14, 4 are socially dry and 9 are continent. CONCLUSIONS: Posterior urethral obstruction after exstrophy closure markedly decreases the success of staged bladder reconstruction, presents a significant risk to the upper urinary tract and should be detected early.

Duplicate bladder exstrophy: a unique approach to initial repair.

OBJECTIVES: To describe a unique approach to the management of duplicate bladder exstrophy combining initial bladder closure and epispadias repair. Bladder exstrophy has been successfully managed by staged surgical repair with early bladder closure, subsequent epispadias repair, and, finally, bladder neck reconstruction. Duplicate bladder exstrophy is a rare variant of the exstrophy complex with fewer than 20 cases reported. METHODS: A male newborn presented with the appearance of both bladder exstrophy and a ruptured omphalocele. Repair of the omphalocele and bilateral orchiopexy was performed shortly after birth, but bladder closure was delayed until there was complete healing of the omphalocele defect, and the investigators believed the infant was ready for abdominal wall and bladder exstrophy closure. At age 8 months, bladder closure was performed with the intraoperative finding of a duplicate bladder lying posterior to the exstrophied bladder. The left ureter drained on the exstrophic bladder plate, and the right ureter drained into the posterior (internalized) duplicate bladder. After anterior innominate and vertical iliac osteotomies, the left ureter was reimplanted into the posterior bladder. A portion of the exstrophied bladder was then tubularized to construct a neourethra of the epispadic penis. RESULTS: The child has done well with an excellent cosmetic appearance of the abdominal wall and a straight phallus. The bladder subsequently required a Mitrofanoff-type continent stoma along with bladder augmentation, which was performed at the time of his Young-Dees-Leadbetter bladder neck reconstruction (age 3.5). The child is currently continent but requires intermittent clean catheterization through his appendicovesicostomy. CONCLUSIONS: The investigators report a unique and unexpected variant of bladder exstrophy and its successful management.

Newborn exstrophy closure and epispadias repair.

Over the last 150 years, bladder exstrophy has undergone a transition from a primarily nonsurgically treated disease to a disease treated by urinary diversion or staged repair and now, possibly, primary newborn reconstruction. Our enthusiasm for primary reconstruction arises because of its potential to simplify the management of this disorder and optimize the return of normal bladder function for these patients. As with most new concepts, the evolution of our primary reconstruction techniques could not have been achieved without the prior efforts of others. Other surgeons such as H.H. Young and J. Ansell have shown us the possibility of achieving urinary continence with primary newborn exstrophy closure without sacrificing renal function, but the results have been inconsistent in the past. Staged reconstruction for bladder exstrophy demonstrates the possibility to achieve consistent successful rates of continence in these patients. However, multiple surgical procedures are required to attain this success. The preliminary results of our series of primary bladder exstrophy closures has encouraged us to perform it for all neonates referred to our institution with bladder exstrophy as well as to use it as part of staged reconstructive efforts for patients who have undergone primary surgical procedures for exstrophy elsewhere. We are hopeful and optimistic that newborn primary exstrophy closure performed as described herein will produce consistent rates of urinary continence and allow normal voiding function as well.
