Development of elastic fibres in the upper urinary tract.

The development of elastic fibres in the upper urinary tract was studied in 31 fetuses ranging in ovulatory age from 10 to 24 weeks using special staining techniques for elastic fibres. The number, orientation and distribution of elastic fibres are described and correlated with age, ureteric level, and fetal weight. Significantly, before 10 weeks, elastic fibres were few in number, poorly developed, and randomly arranged. After 12 weeks, these fibres became more numerous at each level of the urinary tract, and were seen to develop specific orientation. The findings are described and potential clinical implications are discussed.

Balanitis.

The clinical features of 100 cases of balanitis are described. The condition affects no more than 4% of boys, is commonest during pre-school years (but rare prior to toilet training) and is usually associated with a prepuce which is partly or completely non-retractable. It does not cause phimosis and no single pathogen is involved. Most boys suffer a single episode and circumcision is indicated only for those with recurrent, troublesome attacks.

Peripheral neurology as a predictor of bladder dysfunction in congenital neuropathic bladder.

Urodynamic findings and peripheral neurology were correlated in 62 patients with myelomeningocele. The primary motor and sensory levels bore no relation to bladder dysfunction. The ano-cutaneous reflex was a useful predictor, in that where the reflex was positive there was likely to be detrusor hyper-reflexia, a competent bladder neck and absence of sphincter weakness leakage. Where the reflex was absent, detrusor hyper-reflexia was absent or mild, the bladder neck usually incompetent and sphincter weakness leakage common. (Detrusor compliance could not be predicted from peripheral neurological findings). We consider the ano-cutaneous reflex to be a useful indication of bladder dysfunction and urodynamic studies are often unnecessary when it is positive.
