[Bladder neck urethral obstructions of neurogenic bladder in children (author's transl)].

The study of 62 bladder neck and urethral obstructions among 210 neurogenic bladder in children, allow to give an urologic definition, corroborated by urodynamic exploration.--28 boys show lesions of external sphincer as described in traumatic paraplegia in adult. The treatment in external sphincterotomy: by perineal approach (5 cases : 1 success--4 failures), or retropubic (3 cases : 2 successes--1 failure) and mainly endoscopic (12 successes over 21 primary resections, and 8 successes over 10 repeated interventions). The results are given according to the obstruction, the continence and urinary upper tract. Ureteroneocystostomy il allowed by obstruction release. The pathogeny of obstruction is discussed according to the paralysis of the sphincter, as well as the therapy with the comparison between sphincterotomy and self-catheterism.--34 girls present 3 kinds of obstruction;--bladder neck dysectasia (5 cases) with obvious radiologic findings: YV plasty was done with in 2 cases ureteroneocystostomy;--posterior downfall of the bladder where intermittent catheterization provides excellent results;--pure urethral obstruction is also observed, like in boy's external sphincter lesion. Various types of therapy are discussed, specialy TV plasty extented to the urethral meatus, but in girls the intermittent catheterization which respects continence and which can be associated to an ureteroneocystostomy or a pharmacologic therapy is at present the most appropriate method.

Urodynamics of neurogenic bladder in children. A comparative study with clinical and radiological conclusions.

The clinical, radiological and urodynamic investigations of 83 children are presented. Neuropathic bladders were divided into 2 main categories: those without outflow obstruction (36 patients) and those with outflow obstruction (47 patients). Although clinical and radiological findings proved sufficient for the management of these patients, the urodynamic investigations led to a precise diagnosis of the type of neuropathic bladder, an understanding of the mechanism of obstruction and, during follow-up, demonstrated the appearance of obstruction before this was shown radiologically.

Bilharziasis of urinary bladder and ureter: comparative histopathologic study.

The relative incidence and intensity of oviposition in schistosomiasis in different layers of both the urinary bladder and the ureter are presented. Histopathological changes in both organs are elucidated. Oviposition was heaviest in the submucosa of the urinary bladder, while the muscle layer was affected in 15% of specimens. Oviposition was mainly periureteral and in outer muscle layer of the ureter, and was present in only 22% in the ureteral submucosa. Epithelial changes, namely, Brunn nests, cystitis glandularis, cystitis cystica, and squamous metaplasia, were more marked in the bladder specimens than in the ureteral specimens. Squamous cell papilloma and squamous metaplasia associated with acanthosis of the bladder specimens were identified. Results indicate unanimously that the heavy deposition of ova in the submucosa of the bladder leads through its mechanical and toxic irritation to marked epithelial and premalignant changes which pave the way for the disturbing frequency of carcinoma of the bladder in the bilharzial patients which is not the case in the ureter.
