“…A number of studies have suggested presence of detrusor overactivity in enuretics (7,13,28). Watanabe and Azuma (29) found enuretics had more unstable contractions at night than at daytime.…”

In this article, the authors propose a non-invasive method to evaluate children with enuresis by correlating findings of color Doppler ultrasound of ureteric jet and bladder wall thickness. The authors compared the ultrasound findings in a group ABSTRACT:To test the hypothesis that the presence of nocturnal enuresis is related to increased frequency of immature vesicoureteric function, which is further associated with detrusor overactivity, we compared the incidence of immature monophasic ureteric jet in children with and without nocturnal enuresis. The relationship between monophasic ureteric jet Doppler wave form and bladder wall thickness was further explored in the enuresis group. Ultrasound examinations were performed in 511 children suffering from nocturnal enuresis and 266 normal controls. Doppler wave forms of the ureteric jet on each side and the bladder wall thickness after voiding were recorded. Standard urodynamic studies were obtained in 203 enuretic children for correlations with ultrasound findings. There was a significant increase in the incidence of monophasic ureteric jet waveforms in enuretic children when compared with the controls (19.2% versus 6.4% on the right side, 19.2% versus 8.3% on the left side, all p Ͻ 0.01). Furthermore, immature monophasic waveforms were more commonly seen in the enuretic group with markedly thickened bladder wall. Enuretic children with bilateral immature ureteric jet waveforms and markedly thickened bladder wall showed multiple significant urodynamic abnormalities (p Ͻ 0.05). The above observations could be accounted for by immaturity of both vesicoureteric junction and detrusor muscle.

“…The simultaneous evaluation of detrusor and external sphincter function may be obtained by combined cystometry and EMG of the peri-urethral striated musculature (Diokno et al, 1974). With this technique the behaviour of the external sphincter can be evaluated during bladder filling and micturition.…”

Summary. During the last decade a variety of urodynamic techniques have been developed.Despite this there is a tendency to be somewhat inflexible in the application of urodynamics; as soon as the investigator becomes familiar with one method he tends to use it for all his urodynamic evaluations.A short survey gives information about the most popular urodynamic methods with their combinations, as well as their clinical value for paraplegics. The type and number of urodynamic techniques used at the Rehabilitation Centre BadHaring during the last 6 years demonstrate that extensive facilities are desirable.This gives the flexibility to choose the proper technique, giving maximal informa tion for the individual patient with minimal costs.The combination of cystometry with X-ray videography (the simplest form of videourodynamics), is the most frequent method used, whereas the time consuming combined pressure-flow-EMG-X-ray-video-studies are only used for special indications (approximately 10 per cent of all our urodynamic studies).In order to obtain information of clinical value sometimes a compromise is necessary in order to find the method somewhere between what we would like to measure and the disturbance caused to the patient.

“…This condition named detrusor sphincter dyssynergia (DSD) has been known for a long time in patients with supranuclear neurogenic bladder dysfunction as seen in myelomeningocele and multiple sclerosis. Under these conditions it leads to severe func tional obstruction, often with dilatation of the upper uri nary tract and impaired kidney function [1],…”
