Left lateral retroperitoneoscopic total nephrectomy of a horseshoe kidney in a 3-year-old boy.

The unilateral or bilateral approach for nephrectomy in horseshoe kidney by minimally invasive surgery has been described. A total binephrectomy by a unilateral retroperitoneoscopic approach was performed for congenital nephrotic syndrome. A unilateral retroperitoneoscopic approach was planned in a 3-year-old boy (13 kg) with congenital nephrotic syndrome resistant to steroids with massive protein loss. The operative time was 160 min. The postoperative course was uneventful with continued hemodialysis until renal transplant 18 months later. The unilateral retroperitoneal approach allows total nephrectomy to be completed safely in horseshoe kidney for benign disease. The retroperitoneal access preserves the abdominal cavity, should peritoneal dialysis be required.

[Anorectal malformations]. / Malformations ano-rectales.

Anorectal malformations (ARM) are the result of an abnormal development of the terminal part of the digestive tract interesting anus and/or rectum that occur early between the sixth and tenth week of embryonic development. They carry a malformation spectrum of severity depending on the level of disruption of the anorectal canal and of the associated caudal malformations (sacrum and spine). ARM are associated in over half the cases with other malformations that can be integrated in some cases in known syndromes. If surgical treatment to restore anatomy as normal as possible is indispensable, post-operative care is essential for these patients whose defecation mechanisms are altered, to reach if not continence, at least a socially acceptable cleanliness.

Outcome of the Lima periurethral constrictor in children and adolescents: a European perspective.

PURPOSE: The Lima constrictor was described in 1996 as a less complex and less expensive alternative to the artificial urinary sphincter for use in cases of pediatric neuropathic sphincter incontinence. The device provides a fixed periurethral resistance which creates continence, yet allows urethral catheterization without the need to deflate the cuff. We report our multicenter experience, and continence, revision and erosion rates. MATERIALS AND METHODS: We performed a retrospective review of 14 consecutive patients who underwent insertion of the periurethral constrictor (Silimed, Rio de Janeiro, Brazil) between 2005 and 2011. Data are presented as medians (range). RESULTS: A total of 14 patients (13 male, 1 female) with spina bifida (10), sacral agenesis (3) and Hirschsprung disease (1) underwent insertion of the constrictor at a median age of 12 years (range 8 to 20). All patients were wet despite clean intermittent catheterization, medical therapy and/or previous surgery. Eleven patients underwent simultaneous bladder augmentation and/or Mitrofanoff formation. The constrictor was activated a median of 8 weeks (range 2 to 99) after the procedure in 11 patients whereas 3 became dry without activation. Complications occurred in 4 patients (29%), including spontaneous bladder perforation and constrictor erosion (1), tubing disconnection requiring revision (2) and wound infection (1). At a median of 23 months of followup (range 7 to 77) 13 patients were dry and 1 was damp. All patients performed urethral or Mitrofanoff clean intermittent catheterization. The continence rate with the device in situ was 92%. CONCLUSIONS: At a median followup of 23 months the Lima constrictor provided a 92% continence rate with erosion and revision rates of 7% and 14%, respectively. Interim results suggest that the constrictor provides a safe and effective surgical option, particularly in patients who are unable to void to completion.

Outcome of continence procedures after failed endoscopic treatment with dextranomer-based implants (DEFLUX®).

PURPOSE: To evaluate outcome of further continence procedures after failure of endoscopic injections of dextranomer-based bulking agent. MATERIALS AND METHODS: From 1997, 89 children (3-18 years) and one young adult were treated for incontinence with 145 endoscopic injections of dextranomer. On evaluation, each patient was classified as: dry, significantly improved, or treatment failure. Eighty-five patients had at least 12 months of follow up. Out of 34 (40%) treatment failures, 24 patients had a subsequent bladder neck procedure: artificial urinary sphincter (7), bladder neck plasty (9), bladder neck closure (1), fascial sling (3). Six patients had further endoscopic treatment (including 2 after bladder neck plasty). RESULTS: At surgery, Deflux(®) paste was easily identified with minimal surrounding tissue inflammatory reaction. Artificial urinary sphincter: all 7 dry; bladder neck plasty: 7 dry, 1 improved and 1 still incontinent; 1 bladder neck closure patient dry; fascial sling: 1 significantly improved and 2 dry. Repeated endoscopic treatment: 1 dry, 1 improved and 4 failed. Eleven of the 21 (52%) patients who are either dry or improved have voiding abilities. CONCLUSION: Endoscopic injections with dextranomer do not adversely affect the outcome of further surgical procedures. Repeated injections after a previous endoscopic treatment failure have a low success rate.

Hypospadias: surgery and complications.

The aim of this review is to summarize the various steps of the surgical procedures to treat a hypospadias. Hundreds of procedures have been described but most of them follow the same principles. They include correction of a ventral curvature, the urethroplasty itself and penile skin reconstruction. Most of the affected children may be treated with a one-stage procedure. Each hypospadias surgeon has to know a variety of techniques and tailor the procedure used for each individual child. Complications are frequent after the hypospadias correction. Fistulas are the more frequent of these complications occurring in less than 5% of anterior cases, but up to 50% in posterior cases. Long-term follow-up is mandatory to evaluate the sexual outcome of the adults operated on during childhood for a posterior hypospadias, even if the available data seem reassuring.

[Isolated primary nocturnal enuresis: international evidence based management. Consensus recommendations by French expert group]. / Enurésie nocturne primaire isolée: diagnostic et prise en charge. Recommandations par consensus formalisé d'experts.

OBJECTIVE: The causes and treatment of isolated primary nocturnal enuresis (PNE) are the subject of ongoing controversy. We are proposing consensus practical recommendations, based on a formalised analysis of the literature and validated by a large panel of experts. METHODOLOGY: A task force of six experts based its work on the guide for literature analysis and recommendations and recommendation grading of the French Haute Autorité de Santé (formalized consensus process methodological guidelines) to evaluate the level of scientific proof (grade of 1 to 4) and the strength of the recommendations (grade A, B, C) of the publications on PNE. As a result of this, 223 articles from 2003 on were identified, of which only 127 (57 %) have an evaluable level of proof. This evaluation was then reviewed by a 19-member rating group. Several recommendations, poorly defined by the literature, had to be proposed by a professional agreement resulting from a consultation between the members of the task force and those of the rating group. For its final validation, the document was submitted to a reading group of 21 members working in a wide range of specialist areas and practices but all involved in PNE. RESULTS: The definition of PNE is very specific: intermittent incontinence during sleep, from the age of 5, with no continuous period of continence longer than 6 months, with no other associated symptom, particularly during the day. Its diagnosis is clinical by the exclusion of all other urinary pathologies. Two factors must be identified during the consultation: nocturnal polyuria promoted by excessive fluid intake, inverse secretion of vasopressin, snoring and sleep apnoea. It is sensitive to desmopressin; small bladder capacity evaluated according to a voiding diary and the ICCS formula. It may be associated with diurnal hyperactivity of the detrusor (30 %). It is resistant to desmopressin. Problems associated with PNE are: abnormal arousal threshold, attention deficit hyperactivity disorder (ADHD) (10 %), low self-esteem. The psychological component is not very significant. CONCLUSION: PNE is not psychological in origin. The management of this condition includes: evaluating the intrafamilial tolerance and the child's motivation, evaluating the rate, the volume of urine and wet nights using a diurnal and nocturnal diary; education (sufficient fluid intake at the start of the day, decrease in hyperosmolar intake in the evening, regular and complete urination); specific treatments: desmopressin for polyuric forms (expected success rate of 60-70 %), alarms for forms involving small bladder capacity (expected success rate of 60-80 %); alternative treatments and/or treatments combined with the preceding ones, for refractory forms: oxybutinin, tricyclic antidepressants (risk). Results obtained with hypnosis, psychotherapy, acupuncture, homoeopathy or chiropractic are not currently validated (insufficient level of proof).

Long-term desmopressin response in primary nocturnal enuresis: open-label, multinational study.

BACKGROUND: Primary nocturnal enuresis (PNE) is a distressing condition, particularly in severe cases (> or = 3 wet nights/week). A prevalent pathophysiological mechanism, especially in monosymptomatic PNE (PMNE), is commonly believed to be an insufficient increase in night-time release of antidiuretic hormone. Desmopressin, a synthetic analogue of antidiuretic hormone, has been shown to reduce the number of wet nights experienced by PMNE patients in several controlled trials. AIM: This study was performed to evaluate desmopressin treatment in the real-life clinical setting and was a large-scale, 6-month investigation of efficacy and safety in patients with severe PNE. Predictive factors for desmopressin response were also evaluated. A total of 744 children aged 5 years and above from four countries were involved in the study. RESULTS: At baseline, patients had a median of 6 wet nights/week; at 6 months, 41% of patients had experienced > or = 50% reduction in the mean number of wet nights. Long-term desmopressin treatment was consistently well-tolerated across all ages, with 5% of patients experiencing any treatment-related adverse events. The strength of treatment response was associated with nocturnal diuresis (p < 0.0001) and age (p = 0.0167) in logistic regression analyses. Compliance and dosage were also associated with response and more patients experienced > or = 50% reduction in wet nights after 6 months' treatment than earlier in the study, suggesting the value of persistent treatment. CONCLUSION: This study shows that long-term desmopressin treatment in the clinical setting is effective and well-tolerated in PNE patients of 5 years and upwards. Early improvements in bedwetting of any appreciable magnitude may be rewarding, may facilitate compliance and enable good long-term response.

[Comparison of two sublingual types of desmopressin in 6-year-old and more children with primary nocturnal enuresis. About an international randomized cross-over study]. / Comparaison de deux formes orales de desmopressine chez des enfants de six ans et plus souffrant d'énurésie nocturne primaire isolée. A propos d'une étude internationale randomisée en cross-over (PALAT).

OBJECTIVE: Desmopressin (a structural analogue of hormone arginine-vasopressine) is an effective treatment of primary nocturnal enuresis (PNE). A new oral formulation (oral lyophilisate; Minirinmelt has recently been developed. The principal objective of this study was to compare the preference of patients for the oral lyophilisate versus tablet. METHODS: This open-label, randomized, cross-over study was undertaken at 26 centres across Europe and included patients with PNE. All were already receiving a stable dose of desmopressin tablets 0,2 or 0,4 mg. Two hundred and fourteen patients aged 6 to 15 years were randomised (1:1) to receive the treatment in the order lyophilisate/tablet (n=108) or tablet/lyophilisate (n=106). Each formulation was taken during 3 weeks. RESULTS: Of the patients (intention to treat), 55,2% preferred the oral lyophilisate (p=0,16). Patients less than 12 years (n=153) had a preference for the lyophilisate compared to tablets (60,1%; p=0,015). Efficacy was the same for both formulations in terms of mean incidence of bedwetting episodes per week (treatment difference: -0,08; p=0,33). No serious adverse event was reported. The use was considered to be easy for the two forms (p=0,85). Of patients on the lyophilisate, 94,3% had compliance levels of greater or equal to 80%. CONCLUSIONS: The majority of patients preferred the sublingual lyophilisate. This preference was marked in patients less than 12 years on exploratory analysis. The new formulation of desmopressin requires no water intake and retains similar levels of efficacy and safety than the tablet.

Artificial urinary sphincter in children--voiding or emptying? An evaluation of functional results in 44 patients.

PURPOSE: We evaluated functional results with an artificial urinary sphincter in children and adolescents in terms of complications, continence and voiding ability through followup. MATERIALS AND METHODS: A total of 44 patients (39 males and 5 females, age 8.6 to 29.5 years, median 14) underwent implantation of a pericervical AMS 800trade mark artificial urinary sphincter, primarily for severe urinary incontinence of neuropathic origin, between 1986 and 2005. Of the patients 25 had undergone augmentation cystoplasty previously (8), simultaneously (7) or after implantation (10). Median followup was 5.5 years (range 1 to 18). Complications included dysuria and/or urinary retention (24 cases), worsening of bladder function (13), urethral erosion (2), scrotal erosion (5), mechanical dysfunction (7), infection of the artificial urinary sphincter (2) and accidental puncture of the tubes (2). These complications resulted in 9 removals, 5 deactivations, 6 revisions and 5 total replacements. RESULTS: Of 44 patients 9 (20%) were incontinent after removal of the artificial urinary sphincter. Among the remaining patients 32 (73%) were dry and 3 (7%) were incontinent with a deactivated device. Of the 35 patients with an artificial urinary sphincter in place 17 (48.6%) voided to completion with spontaneous voiding, 9 (25.7%) performed post-void clean intermittent catheterization and 9 (25.7%) emptied exclusively with clean intermittent catheterization. The ability to maintain voiding to completion after implantation was significantly decreased when the artificial urinary sphincter was implanted before puberty (p = 0.0025) or in conjunction with an augmented bladder (p = 0.01). CONCLUSIONS: The artificial urinary sphincter provides a good rate of continence. However, complications are frequent, leading to removal in 20% of the cases. In time only a limited number of patients can empty the bladder without clean intermittent catheterization.

Vesicoureteral reflux and elimination disorders.

Two kinds of elimination disorders can be associated with Vesico Ureteral Reflux (VUR): pure bladder elimination disorders or combination of bladder and bowel elimination disorders. An elimination disorder is always a factor which worsens the prognosis of VUR, as it increases the risk of infectious complications and thus presents a threat for the upper urinary tract. Regarding pure bladder elimination disorders, a chronic urine residue is observed in four clinical situations: the syndrome megacystis-mega ureter; the mega bladder without mega ureter, but with VUR; high grade massive VUR without a mega bladder; organic obstructions of the urethra (such as posterior urethral valves.). VUR associated with urine and fecal elimination disorders cover functional pelvi perineal dyscoordination, bladder sphincter dysynergia, disturbances of visceral motricity and anal sphincter function. The most characteristic type is represented by the neuropathic detrusor-sphincter dysfunction; also enter in this category neurogenic non-neurogenic bladders (Hinman's syndrome); However the vast majority of urine and fecal elimination disorders is represented by non neuropathic perineal dyscoordination associating at various degrees: voiding postponement, lack of sphincter relaxation during micturation, interrupted voiding, and constipation. The diagnosis of elimination disorders associated with VUR is based on non invasive investigations such as anamnesis and drinking/voiding chart in children and adolescents, and "four observation test" in infants. Ultrasound and uroflowmetry are also useful tools. Invasive investigations include mainly voiding cystourethrography and urodynamics, ideally combined in video urodynamic studies. The management of urinary and intestinal elimination disorders is based on the prevention of infections, the suppression of the post voiding residual urine and the treatment of an associated constipation. If surgical treatment of VUR is needed, it must be associated to the management of elimination disorders in the peri operative period. In many instances, an appropriate treatment of elimination disorders often leads to the VUR resolution.

Primary monosymptomatic nocturnal enuresis in children and adolescents.

Nocturnal enuresis (NE) is one of the most frequent paediatric pathologies. The prevalence of primary nocturnal enuresis (PNE) is around 9% in children between 5 and 10 years of age and about 40% of them have one or more episodes per week. Still for too long, PNE has not been recognised as a pathological condition, particularly by the medical community; as a consequence, there was no specific education at medical school, and a poor involvement by the practitioners. Enuretic children have a sense of social difference and isolation; some of them do express a low self-esteem. Also, self-esteem is improved by the management NE even if this management fails to cure the condition. Primary monosymptomatic nocturnal enuresis (PMNE) is an heterogeneous condition for which various causative factors have been identified such as: nocturnal polyuria, sleep disturbances, reduced bladder capacity or bladder dysfunction, upper airway obstruction. The positive diagnosis of PMNE is based on a complete questionnaire and a careful physical examination. A drinking and voiding chart is an essential non-invasive tool: first, to collect information about the initial drinking and voiding habits of the child, then to reassess the accuracy of the diagnosis. Only motivated patients should receive a specific treatment for their NE and the treatment should be proposed based on the type of PMNE. PMNE associated with nocturnal polyuria should be treated with desmopressin, which reduces nighttime urine production. For PMNE with a reduced bladder capacity alarms should be the first-line treatment. Oxybutinin, a drug with anticholinergic properties, is not theoretically indicated for the treatment of PMNE except for a very small subgroup of patients who have an overactive bladder only during sleep. In cases refractory to monotherapy, NE is probably the result of an association of different physiopathological factors (e.g. both a nocturnal polyuria together with a small bladder capacity) some of them are still unknown. In these patients, a combination of treatments may be more effective than monotherapy. Various combination therapies can be proposed to improve the cure rates.

A randomised comparison of oral desmopressin lyophilisate (MELT) and tablet formulations in children and adolescents with primary nocturnal enuresis.

AIMS: Desmopressin is a useful treatment for primary nocturnal enuresis (PNE), a common childhood condition that can persist into adolescence. This open-label, randomised, cross-over study evaluated the preference of children and adolescents with PNE for sublingual desmopressin oral lyophilisate (MELT) vs. tablet treatment, and the efficacy, safety, compliance and ease of use associated with each formulation. In total, 221 patients aged 5-15 years who were already receiving desmopressin tablets were randomised 1 : 1 to receive desmopressin treatment in the order MELT/tablet (n = 110) or tablet/MELT (n = 111) for 3 weeks each. Each formulation was administered in bioequivalent doses (0.2/0.4 mg tablets identical with 120/240 microg MELT). Following treatment, patients were questioned regarding treatment preference. Diary card data and 100 mm Visual Analogue Scale scores were also recorded. RESULTS: Overall, patients preferred the MELT formulation to the tablet (56% vs. 44%; p = 0.112). This preference was age dependent (p = 0.006); patients aged < 12 years had a statistically significant preference for desmopressin MELT (p = 0.0089). Efficacy was similar for both formulations (MELT: 1.88 +/- 1.94 bedwetting episodes/week; tablet: 1.90 +/- 1.85 episodes/week). Ease of use of both formulations was high. Compliance (> or = 80%) was 94.5% for MELT patients vs. 88.9% for the tablet (p = 0.059). No serious/severe adverse events were reported. CONCLUSIONS: There was an overall preference for the MELT, and a statistically significant preference for desmopressin MELT in children aged 5-11 years. Desmopressin MELT had similar levels of efficacy and safety at lower dosing levels than the tablet, and therefore facilitates early initiation of PNE treatment in children aged 5-6 years.

Antenatal isolated hydronephrosis associated with urinoma.

Two cases of prenatally identified urinoma associated with an isolated hydronephrosis are presented, and the pathophysiology and prognosis of this rare condition are discussed. The presence in utero of a peri-renal collection associated with an isolated hydronephrosis seems to be a sign of significant renal dysplasia. These urinomas disappear spontaneously, thus drainage is not necessary, except in the case of compression of surrounding structures. The functional prognosis of these kidneys seems to be most unfavourable.

Quality of life and continence in patients with spina bifida.

PURPOSE: Spina bifida (SB) is the most common congenital cause of incontinence in childhood. This study attempts to determine the relationships between urinary/faecal incontinence, methods of management, and Health Related Quality of Life (HRQoL) in people with SB. PATIENTS AND METHOD: A total of 460 patients (300 adults and 160 adolescents) from six centres in France have taken part in this cross-sectional study. Clinical outcome measures included walking ability, urinary/faecal continence, and medical management. HRQoL was assessed using the SF36 in adults and the VSP in adolescents and their parents. Univariate and multivariate analysis was used to determine the relationships between clinical parameters and HRQoL. RESULTS: HRQoL were significantly lower than in the general population. Adult women had significantly lower scores than men, and adolescent females had significantly lower scores for psychological well being. We did not found strong relationship between incontinence and HRQoL in this population. Moreover patients surgically managed for urinary/fecal incontinence did not show significantly higher scores of HRQoL. CONCLUSION: Using generic HRQoL measures, urinary/faecal incontinence and their medical management may not play a determinant role in HRQoL of persons with SB. However many other factors affect HRQoL in these patients. A longitudinal study design is recommended to assess whether incontinence management is associated with improved HRQoL.

Long-term effects of dextranomer endoscopic injections for the treatment of urinary incontinence: an update of a prospective study of 61 patients.

PURPOSE: To treat sphincteric deficiency in children endoscopic bladder neck injections may avoid or salvage more complex procedures. A prospective study to assess the efficacy of bladder neck injections of dextranomer based implants (Deflux(R)) was done in a 7-year period in 61 patients. MATERIALS AND METHODS: From September 1997 to September 2004 we enrolled in the study 41 males and 20 females 5 to 18 years old with severe sphincteric incompetence, including exstrophy-epispadias in 26, neuropathic bladder in 27, bilateral ectopic ureters in 5, and miscellaneous in 3. Preoperative evaluation consisted of medical history, urine culture, urinary tract ultrasound and videourodynamics. This evaluation was repeated 6 months and 1 year after treatment, and yearly thereafter. Of the patients 17 underwent 2 and 4 underwent 3 treatment sessions to achieve a definitive result. At each evaluation the case was considered cured-a dryness interval of 4 hours between voids or CIC, significantly improved-minimal incontinence requiring no more than 1 pad daily and no further treatment required, and treatment failure-no significant, long lasting improvement. Videourodynamics were mainly useful to study the evolution of bladder capacity, activity and compliance. Followup after the last injection was 6 to 84 months (mean 28). RESULTS: Mean injected volume per session was 3.9 cc (range 1.6 to 12). Postoperative complications were temporary dysuria in 2 patients nonfebrile urinary tract infection in 10, orchid-epididymitis in 1 and urinary retention with pyelonephritis in 1. The incidence of dryness or improvement during followup was 79% (48 of 61 patients) at 1 month, 56% (31 of 55) at 6 months, 52% (24 of 46) at 1 year, 51% (18 of 35) at 2 years, 52% (16 of 31) at 3 years, 48% (12 of 25) at 4 years, 43% (9 of 21) at 5 years, 36% (4 of 11) at 6 years and 40% (2 of 5) at 7 years. The success rate according to pathological condition was similar in cases of neuropathic bladder and the exstrophy-epispadias complex (48% and 53%, respectively). The success rate in re-treated cases was 38%. After treatment a contracted bladder developed in 6 patients. Also, of the 35 patients with at least 2 years of followup an increase in capacity of at least 50% was observed in 12 of 18 with an initially small bladder. No side effects related to the substance were observed. CONCLUSIONS: Endoscopic treatment for pediatric severe sphincteric deficiency with dextranomer implant, a nontoxic, nonimmunogenic, nonmigratory synthetic substance, was effective up to 2 years in half of the patients. Subsequently at up to 7 years of followup a slow decrease in efficacy was observed and treatment remained beneficial in 40% of the patients.

Long-term effects of dextranomer endoscopic injections for treatment of urinary incontinence: an update of a prospective study of 31 patients.

PURPOSE: A prospective study was initiated 7 years previously to assess the efficacy of endoscopic dextranomer based implants for pediatric structural incontinence. Preliminary results revealed that at 3 years 50% of the patients were either dry or significantly improved. We report long-term results in the same cohort of patients. MATERIALS AND METHODS: A total of 33 children and adolescents 5 to 18 years old with severe incontinence due to sphincteric incompetence (exstrophy-epispadias complex in 13, neuropathic bladder in 16, bilateral ectopic ureter in 4) were enrolled. Of the patients 13 underwent 2 and 4 underwent 3 treatment sessions to achieve a definitive result. Mean injected volume was 3.9 ml (range 1.6 to 12) per session. At each evaluation patients were considered cured (dryness interval 4 hours), significantly improved (minimal incontinence requiring no more than 1 pad daily and no further treatment required) or treatment failures (no significant improvement). Videourodynamics were used to study the evolution of the bladder capacity, activity and compliance. A total of 31 patients were followed 3 to 7 years after the last injection. RESULTS: At 3 years after treatment 15 of 30 patients (50%) were dry or improved. One patient who had leakage after 3 years of dryness due to bladder deterioration subsequently underwent ileocystoplasty. At 4 years 12 of 25 patients (48%) were dry or improved. At 5 years 9 of 21 patients (43%) were dry, as were 4 of 11 (36%) at 6 years and 2 of 5 (40%) at 7 years of followup. The success rate according to pathological evaluation was comparable in neuropathic bladders (7 of 14, or 50%), exstrophy (3 of 6, or 50%) and epispadias (3 of 7, or 43%). Of 12 patients who underwent bladder neck plasty before the injection of bulking agent 7 (58%) were either dry or improved. The success rate was higher in males (13 of 23, or 57%) than in females (3 of 8, or 38%). Also, at puberty 2 males who were improved became dry. Bladder capacity increased in 12 of 18 initially small bladders and remained normal and stable in 9, while 4 initially dry patients had development of recurrent leakage secondary to bladder deterioration and underwent augmentation. Otherwise, there were no long-term side effects observed related to the injection of the bulking agent. CONCLUSIONS: Endoscopic treatment of severe organic urinary incontinence with dextranomer is durable for up to 7 years of followup in 40% of the patients.

A multicenter evaluation of urinary incontinence management and outcome in spina bifida.

PURPOSE: We describe urinary continence management and outcome in patients with spina bifida to identify the procedures that are most successful. MATERIALS AND METHODS: In a multicenter retrospective cohort study medical charts were studied. At the same time in a cross-sectional survey sociodemographic characteristics, orthopedic features and urinary continence were described based on the frequency of leakage from the viewpoint of patients or close relatives using a Likert scale of 5 items, namely 1-leakage permanent to 5-leakage never. RESULTS: A total of 421 patients were included, of whom 191 (45%) had been medically treated with a normal voiding pattern according to the patient viewpoint in 21%, clean intermittent catheterization in 61% and no specific bladder emptying method in 18%. The mean leakage score +/- SD was 2.74 +/- 1.55. On the other hand, 230 patients (55%) were surgically treated. Except for 23 patients who underwent noncontinent urinary diversion 207 were considered for treatment and continence description. The mean leakage score was 3.45 +/- 1.60. An artificial urinary sphincter in male and females, and a sling or Kropp technique in females were satisfactory when bladder enlargement was not required. In cases of bladder augmentation without continent diversion an artificial urinary sphincter in males and a bladder neck sling or cinch, Kropp and Young-Dees procedures in females have provided the best results. In cases of bladder enlargement with continent urinary diversion bladder neck closure or a wrap have provided the best results whatever the patient sex. CONCLUSIONS: Many factors may influence the choice of a technique, such as patient sex, bladder characteristics or orthopedic conditions. However, since to our knowledge no randomized, controlled study has been yet performed, definitive conclusions on the best way to achieve urinary continence in patients with spina bifida cannot be established.
