Hydatid cysts of the sacrum are rare entities, characterized by chronicity without any clinical manifestation and are usually misdiagnosed in the early stage resulting in significant loss of bone and destruction of surrounding tissue. One should keep this possibility in mind in cases of early sphincteric involvement with minimal sensorimotor deficit in the lower limbs and bone destruction on radiography.
A spinal cord lesion above the sacral micturition center results in a loss of voluntary control and development of bladder sphincter dysynergia with hyperreflexia of the detrusor and spasticity of the sphincter. Sacral rhizotomy and implantation of an anterior sacral root stimulator appears as an effective method for the treatment not only of voiding dysfunction but also of defecation and sexual disturbance. The surgical technique is described as are the clinical and electrophysiological controls. The results of our series of operated patients with intradural implantation and sacral deaffentation show a constant improvement. 90% have satisfactory continence and no longer require an incontinence appliance. Bladder capacity and compliance have increased to 120% and urethral closure pressure has decreased. 80% have complete voiding or a post-void residue of not more than 50 ml. So, urinary infection rate is dramatically decreased.

The experience is based upon the care of paraplegic patients admitted to the Rehabilitation Centre Tobelbad, near Graz. Pathological changes in the urinary tract are reported as late effects in bladder dysfunctions of paraplegics. The study reviews the late complications of urethra and bladder and outlines the effects of chronic urinary infection, where particular attention is paid to the vesicoureteric reflux. Finally, the problem of urinary stones in paraplegic patients is discussed.
A method of synchronous study for monitoring the pressure activity of the rectum, bladder and urethral sphincter was described. Intrarectal pressures were obtained using a 8 F custom made balloon catheter. Constant urethral infusion with intrasphincteric pressure recording was arranged through a specially designed 12 F trilumen catheter. Simultaneous intravesical infusion and independent bladder pressure recording were conducted through two other channels of this catheter. This radiologic-aided study was used for functional evaluation of the bladder and its outlet. The physical factors, such as urethral infusion flow-rate, and the compliance of the infusion catheter hydraulic system governing the interpretation of the study during voiding and nonvoiding states, were described. With an experience of 145 studies on spinal cord injury patients and normal subjects, this method has been found to be a useful clinical urodynamic technique well suited even to a nonambulatory spinal cord injury patient.
A set-up for combined pressure, flow, EMG and X-ray recording is presented. Some efforts are undertaken to keep artefacts by manipulation, instrumentation and by the investigation itself as low as possible. Using a specially designed, plastic made, radiolucent micturition chair this set-up is especially suitable for the urodynamic evaluation of the lower urinary tract in paraplegics, in myelomeningoceles and other handicapped persons. More than 90 urodynamic studies have been carried out in this way during the last 2 years without any complication whatsoever.
This is a report of a special method of a temporary intravesical electrostimulation of the bladder for the treatment of the urinary incontinence of spina bifida children. The technique with presentation of apparatus and catheter is described in detail. The criterias for the selection of the patients are explained, the most important of which is the response of the detrusor muscle during the stimulation recorded by uromanometry. 26 spina bifida children were treated. There is at least a success in 50% of the patients, if the criteria are fulfilled.
The resistance-inducing capacity of ciprofloxacin is still controversial. In order to assess the changes in susceptibility behavior, ciprofloxacin was given as antibiotic cover for transurethral maneuvers in multiple sclerosis (MS) patients with urinary tract infection prone to recurrence after treatment. The aim was to compare the susceptibility pattern before and after treatment in a double-blind study using two different dose regimens. Sixty-one patients were randomly separated in two groups who received 100 and 500 mg ciprofloxacin orally, twice a day for 4 days. Bacterial cultures were performed before and at the fourth day of treatment as well as at 6 days and 4 weeks after the end of treatment. Altered susceptibility behavior, defined as an elevation of the primary minimum inhibitory concentration by at least two dilution steps, was only found in three causative organisms out of 86, demonstrating the low resistance-inducing capacity of ciprofloxacin. There was no significant dosage-related difference.
