Management of failed bladder exstrophy closure in adolescence and adulthood

Patient-Reported Impact of Pelvic Organ Prolapse on Continence and Sexual Function in Women With Exstrophy-Epispadias Complex

OBJECTIVE

This study aimed to characterize long-term urogynecologic issues of women with a history of bladder exstrophy and pelvic organ prolapse (POP) and to assess the impact of POP repair on continence and sexual function.

DESIGN

Patient demographics and surgical history related to exstrophy and POP were collected through chart review. Patient perceptions regarding sexual function, urinary continence, and quality of life were assessed through Web-based administration of validated questionnaires: International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form and POP-Urinary Incontinence Sexual Questionnaire.

SETTING

Maryland, United States.

PARTICIPANTS

Review of a single-institution exstrophy-epispadias complex database resulted in 25 adult female patients with a history of POP treated at the authors' institution. Eleven patients participated and were included in the analysis.

MAIN OUTCOME MEASURES

Urinary continence and sexual function.

RESULTS

All participants underwent surgical repair for prolapse, with 7 (63.6%) experiencing unsuccessful initial repair and subsequent recurrence. Median total number of POP repairs was 2.5 (1-4). After correction of POP, patients reported a median improvement in International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form scores of 11 (21 to -1) of 21 and in POP-Urinary Incontinence Sexual Questionnaire scores of 9.5 (6.5-33.0) of 48.0. With regard to urinary continence, 6 (54.5%) patients presently reported no incontinence, 3 (27.3%) reported mild incontinence, and 2 (18.2%) reported continuous incontinence.

CONCLUSIONS

Pelvic organ prolapse poses significant reductions in quality of life for women born with exstrophy, with effects on urinary continence and sexual function. Identification and correction of prolapse seems to result in notable improvements in the lives of these patients.

The application of pelvic osteotomy in adult female patients with exstrophy: applications and outcomes

OBJECTIVE

• To apply the technique of pelvic osteotomy to a select group of adult female patients with exstrophy, in view of the low complication rate and acceptable success rate of the technique.

PATIENTS AND METHODS

• We applied this technique as an adjunct to uterovaginal suspension and abdominal wall repair after our prior success in treating patients with extreme pelvic diastasis. • Bilateral innominate (transverse) and vertical iliac osteotomies were done from an anterior approach and an external fixator was placed. The fixator and pelvic bones were gradually cranked together over a period of 2-3 weeks until the diastasis was less than 4 cm. • Then sacrocolpopexy was performed with revision of the abdominal wall and revision genitoplasty along with the placement of an intrasymphyseal titanium plate.

RESULTS

• Six patients presented with uterine/vaginal prolapse and concerns about the appearance of their abdominal wall and genitalia. Three patients had undergone uterine suspension before and one patient had had five prior attempts at suspension, which failed. The mean (range) age was 22.3 (18-26) years. • All the patients underwent staged reduction of pubic diastasis and sacrocolpopexy along with revision of the abdominal wall and in four cases revision genitoplasty was also performed. The mean (range) diastasis was 12.8 (8-18) cm and 2.8 (3-4) cm before and after staged reduction respectively. • Complications included transient femoral nerve palsy (two) and foot drop secondary to sciatic nerve stretch (one), which resolved with time. The symphyseal plate needed to be removed in three patients: secondary to persistent pain at the site (one), persistent discharge from the lower abdominal wound (one) and erosion into the anterior wall of the vagina (one). • At a mean (range) follow-up of 60.7 (2-137) months the cosmetic and functional outcome of the abdominal wall reconstruction and genitoplasty was good with all the patients being satisfied. Five patients are currently sexually active and none has had a recurrence of their prolapse. None has become pregnant yet.

CONCLUSIONS

• Although the morbidity of this procedure in the adult is not insignificant, it is a valuable adjunct to pelvic floor reconstruction in young women of childbearing age even in those who have had prior suspension procedures. • In addition, it allows the movement of lateral previously unoperated skin into the midline, allowing scar and skin replacement with healthier more vascularized tissue.

Female Exstrophy: Failure of Initial Reconstruction and its Implications for Continence

PURPOSE

Bladder exstrophy is a rare malformation affecting only 1 female out of every 5 patients. In the female initial closure is combined with reconstruction of the outer genitalia, and urinary continence can be achieved by some girls without the need for later bladder neck reconstruction. We evaluated the management and outcome of failed initial closures in the female exstrophy population.

MATERIALS AND METHODS

We performed a retrospective database review of patients with the exstrophy complex. Females with classic bladder exstrophy with failure of initial closure were identified. Age at initial closure, use of osteotomies, reasons for failure and number of closures, as well as definitive treatment and long-term outcomes were evaluated.

RESULTS

Of 71 females with classic bladder exstrophy 14 had failure of initial closure. Of these patients 1 had undergone initial closure at our institution and 13 were referred for reclosure. Mean followup was 6.5 years (range 3 to 12) and mean age was 10 years (4 to 14). The patients underwent a maximum of 3 closures (mean 2.4). Initial osteotomies were performed in 4 patients, no osteotomy in 8 and status was unknown in 2. Reason for initial failure was dehiscence in 11 patients and prolapse in 3. Five patients underwent a second closure elsewhere. On referral reclosure was successful using osteotomies in all patients. Bladder neck reconstruction was done in 5 patients (3 are daytime continent) and continent diversion in 4 (all are dry). The other patients are awaiting final treatment.

CONCLUSIONS

The single most important step to achieve urinary continence is successful initial bladder and posterior urethral closure. Pelvic osteotomies ensure a tension-free closure and enhance bladder outlet resistance. Radical mobilization of the vesicourethral complex allows placement of the bladder deep within the pelvis. Failure of the initial closure in the female exstrophy population has a severe impact on long-term outcome and quality of life.

The role of computed tomography in modern paediatric uroradiology

Computed tomography (CT) has developed a well-recognised role within paediatric uroradiology, especially in imaging of trauma, malignancy (in particular Wilms' tumour), atypical infection, and congenital urogenital abnormalities. CT can also be used for problem solving in nephrolithiasis and renal transplant assessment. These applications are illustrated and discussed, with an emphasis on particular information that can be gained from the CT study.

Hypospadias and bladder exstrophy

Reconstructive surgery for patients with hypospadias, bladder exstrophy and cloacal exstrophy is challenging. Over the last few years, more and more data have become available concerning incidence and epidemiology, as well as short- and long-term results of surgical techniques. The tubularized incised plate urethroplasty for hypospadias repair continues to gain in popularity. However, the results of long-term studies of larger series supporting this enthusiasm are still missing. Buccal mucosa is more frequently used in complex hypospadias cases with good short- and long-term results. The one-stage approach of exstrophy repair seems to be promising. However, failures, which require very complex reconstructions, are also reported. Urodynamic studies demonstrated severe abnormalities of bladder function even in continent patients. Therefore, one must question the normality of voiding patterns, and the price to be paid in achieving continence for patients with exstrophy. Achievement of continence for urine and stool is possible for patients with cloacal exstrophy. The colon should be preserved and should not be used for bladder or vaginal reconstruction. The incidence of neoplasia in patients with bladder exstrophy seems to be higher than expected. However, only one cohort study is presently available.
