[Experiences in the diagnosis and therapy of neurogenic disorders of bladder emptying].

Today extensive urodynamic investigations are indispensable for diagnosing and for an on-target treatment of neurogenic bladder dysfunction. Classifications and forms used according to functional aspects are explained. Possible treatment methods are commented in respect of own experiences, especially with regard to chemotherapy, intermittent catheterisation, transurethral electrostimulation, biofeedback therapy and supravesical urinary diversion.

[New trends in diagnosis and therapy in pediatric surgery].

The advent of new and improved diagnostic methods has had favourable bearings on therapeutic achievements in paediatric surgery. Ultrasonography, computer tomography, manometry, and endoscopy are major examples of relevance. Prenatal diagnostic ultrasonography has been assuming a growing role in prenatal detection of malformations. Postnatal corrective surgery can thus be properly planned and performed under conditions which are optimum for mother and child. Many examples are given to demonstrate that in today's paediatric surgery possibilities for diagnosis and therapy have substantially improved, last but not least, owing to efficient interdisciplinary cooperation.

[Compartment pressure measurements with a wick catheter].

There is no generally accepted method for compartmental pressure measurement, as yet. Substantial disadvantages are implied in methods based on outflow resistance measurement, and, above all, these methods are hardly suitable for long-time pressure measurement nor for objectivation of dynamic pressure alterations. Described in this paper is the authors' own method, using a wick catheter. It is highly reproducible and is characterised by high measuring dynamics. A comparatively large amount of hardware is required. Evidence is produced to the impact of differentiated conditions of examination on measuring results. Values measured by means of this method in the anterotibial compartment of the lower leg did not normally exceed a pressure level of 2.0 kPa.

[Appendicitis in childhood].

Appendicitis in infancy has proved to be accompanied by particular problems in general and differential diagnosis. Recommendations are made for proper establishment of case histories as well as for clinical examination and surgical approach, with reference being made to the authors' own experience. The authors' perforation rate was 7.3 per cent in more than 1,000 appendectomies on children (up to 20 per cent in literature). Reported in this paper is experience obtained from treatment of severe cases.

[Studies following bladder reconstructions in cystoschisis].

The question how to perform the best surgical repair of bladder exstrophy is still being discussed. By various urodynamic investigations following bladder reconstruction we came to the conclusion that the new built bladder and its outlet tract can function normally.

[Clinical course and therapy of fecal incontinence in children].

Among the operative techniques for correction of anal incontinence the transplantation of small striated muscles, which has to be denervated before, is hopeful. In the conservative treatment biofeedback techniques are of great interest. New diagnostic procedures (combined manometric and electromyographic readings of the anal sphincter pressure) allow a better understanding of the individual type of anal incontinence. There are a lot of technical proposals aimed at overcoming anal incontinence. Among them the free transplantation of autogenous muscle can be regarded as a step in the forward direction. As far as conservative treatment is concerned the biofeedback treatment seems to be of interest.

[Therapy of urine incontinence by electro-stimulation (author's transl)].

The most common cause of urine incontinence in childhood is a neurogenic disturbed micturition in cases of myelo-dysplasia. Of decisive significance for the diagnosis and choice of therapy are urodynamic examinations. A report is given on the effectiveness of the author's own examinations using transurethral electro-stimulation.

[Forearm fractures in childhood (author's transl)].

Forearm fractures are the most frequent fractures in childhood. We were treating 759 fractures of this kind. Our results obtained were compared with other authors dealing with this subject. The treatment of choice is conservative. Only in 1.9% surgical measures (osteosynthesis) are required. Refractures are mostly caused as a result of short immobilisation. Compared with those values to be found in literature (7 to 9%) we observed refractures only in 0.3% of our cases.

[Perinatal injuries of skeletal system].

Perinatal injuries to the skeletal system are quite rate and observed in no more than something between one and three per cent of all newborns. Injury of the mother short time before childbirth, metabolic disorders, inflammatory processes, genetic defects or intrapartum complications, which call for no-delay control in the interests of mother and child, are some of the common causes. Reference is made to diagnosis, differential diagnosis, and treatment for various types of injuries, against the background of the authors' own experience.

[The influence of intravesical electrostimulation on the urinary bladder in animals (author's transl)].

The mechanism of the effects of endovesical electrostimulation on the bladder wall was examined in experimental animals. Histochemical examinations showed no changes of any kind in the activity of enzymes in the detrusor area. In the out-flow region of the bladder an increase in the activity of malatedehydrogenase, alpha-glycerophosphate-dehydrogenase, acid phosphatase and acetylcholinesterase were found histochemically. The effects of the current applied are confined to this region. This agrees with the results of clinical examinations.

[Functional dynamics of obstructive ileal conduits in children (author's transl)].

Bad late results following ileal conduit are usually caused by stomal obstruction. Poor emptying of the conduit, ureteric reflux and infection all combine to produce a pathological result. A manometric procedure to assess the functional performance of the conduit is presented. This allows for the diagnosis of early obstruction and decompensation. The most important measurements are a resting pressure of 1.2 kPa and the emptying pressure of 1.7 kPa and a compliance varying from 10 ml per kPa to 71 ml per kPa. The conduit must be isoperistaltic.
