Treatment of detrusor hyperreflexia in multiple sclerosis: a double-blind, crossover clinical trial comparing methantheline bromide (Banthine), flavoxate chloride (Urispas) and meladrazine tartrate (Lisidonil).

34 patients suffering from detrusor hyperreflexia due to multiple sclerosis entered the trial and 32 patients accomplished. The patients received each drug for a period of 14 days. The patients made records of relevant symptoms, urgency and urge incontinence and compared the treatment periods according to these symptoms. Registration of the number of micturitions was also made. Furthermore, the patients underwent cystometric studies. The following parameters were recorded and compared: residual urine, volume at the first bladder contraction, effective volume and amplitude of the first bladder contraction. The study showed that the patients preferred methantheline bromide. The entire cystometric pattern changed statistically significant with methantheline bromide, but only with concordance to the patients preferences in 60%. Decrease in number of micturitions and volume at the first bladder contraction were the only parameters showing accordance with the preferences. The drugs caused many various side effects. 12 treatment periods were discontinued due to side effects of meladrazine tartrate. The cystometric recordings seem to be of little use in evaluation of a drugs therapeutic effect, and it is difficult to find parameters which reflect the patients preference of the drugs.

Disturbances of micturition in Parkinson's disease.

During the years 1970-1974, a total of 44 patients referred by neurologists to the Urological Laboratory were classified in the following groups: paralysis agitans (27), postencephalitic parkinsonism (5), cerebral arteriosclerosis and parkinsonism (7) and cerebral arteriosclerosis and parkinsonism, suspected (5). Bladder function was assessed on the basis of cystometry and urodynamic investigation. A high frequency of supranuclear bladder paresis (SNP) was found, although unequally distributed in the different diagnostic groups. Stereotactic operations on the thalamic nuclei seemed to be correlated with SNP. The question was raised whether SNP was part of the parkinsonian syndrome or merely signs and symptoms related to ageing.

Neurological disorders and detrusor hyperreflexia.

In 152 consecutively selected patients with detrusor hyperreflexia (DH) 96 (63 per cent) had neurological disorders. Thirty-two patients did not show any primary neurological or urological cause for DH. This group was chosen to elucidate the evaluation of possible neurological symptoms in relation to the urological symptomatology. Nine had died and one failed to appear to the neurological examination. Twelve (63 per cent) of the 22 examined patients showed signs of lesions in different parts of the central nervous system, particularly cerebrovascular diseases and myeloneuropathy. Six had had neurological symptoms for years. In two the urological symptoms were first to appear. In the group with no neurological complaints the urological symptoms had existed for 2-30 years. No essential difference was found in the degree of voiding disturbance whether or not neurological signs were disclosed. It is concluded that the discovery of DH should be followed by a neurological examination to disclose further signs of lesions in CNS. Likewise, an extended urological examination with demonstration of DH might help in the evaluation of an obscure neurological disease.

Detrusor hyperreflexia. A survey on its etiology and treatment.

Detrusor hyperreflexia (DH) is a frequently occurring condition. The symptomatology is characterized by frequency, urgency and urge incontinence. DH is defined as involuntary, uninhibited detrusor contractions. The physiology and pathophysiology of the micturition reflex is reviewed. The balance between cerebral stimulation and supraspinal inhibition is discussed. DH is caused by disturbances in this balance. Whereas increased afferent impulses to the central nervous system due to local disorders in bladder and/or urethra may produce DH, a neurological disorder affecting the inhibitory nervous pathways from cortical and subcortical centres always result in uninhibited detrusor contractions. DH was found in 25% of 2000 patients. In the majority of the patients the DH was caused by a neurological disorder. The incidence of DH in patients with enuresis, gynecological patients with urinary incontinence and/or genital prolapse and patients with benign prostatic hyperplasia (BPH) is reported. In 62% of the patients with BPH the DH was eliminated after adequate surgical treatment of the infravesical obstruction. By contrast, DH in women with genital prolapse and/or incontinence persisted despite operative treatment. In a retrospective investigation of 152 patients with DH, the cause of the DH was unknown in 32 patients (21%). A clinical neurological examination revealed no evidence of neurological disease in 45% of the 22 patients examined. Voiding symptoms were the only complaint in these patients as well as in 30-40% of the patients in the other groups mentioned. This calls for improved investigatory methods in the evaluation of the balance between stimulation and inhibition of the micturition reflex. The presence of uninhibited detrusor contractions in apparently healthy patients should indicate a neurological examination since DH may be the first sign of a neurological disorder. The micturition reflex is conducted through long, uninterrupted neurons with a marked central integration. Therefore cystometry may be used as a supplement to the clinical neurological examination in the early diagnosis of pyramidal or extrapyramidal central nervous system disorders.
