[Male idiopathic bladder atonia--origin of occasional failures of bladder neck operations].

The rare idiopathic atony of the urinary bladder in man becomes important when it determines the failure of an operation of the neck of the vesicle. Among 200 patients with vesical retention after all 5 cases of primary weakness of the detrusor were found. The compulsory cystomanometry is often not possible during the normal consulting hours or the clinical work on account of the more and more increasing number of patients with diseases of the neck of the vesicle. The measuring of the maximum miction pressure during the endoscopic examination is recommended as screening without greater expenditure.
