[The interprostatic "partial catheter" (urologic spiral) II].

The intraprostatic partial catheter or the so-called "Urological Spiral" (US) is a novel development which was first used and tested with suitable urological patients in May 1978. - The "Urological Spiral" which is made of coiled rust-proof steel and can be used for implantation purposes can give unimpaired spontaneous miction back to patients where an operative removal of the prostatic urethra occlusion (caused by prostate adenoma or prostate carcinoma) has not been feasible by the therapeutic methods known so far. With inlying US the physiological valve function of the urethra makes a spontaneous healing up of an ascending bladder infection possible caused by ascension. The patency of the prostatic urethra is optimally secured by the shape und the elastic construction of the US. Judging from the experiences gained so far there are no essential contra-indications and the complication rates are very low. Insertion and removal of the US can be carried out by common urological instruments as e.g. urethroscope and elastic foreign-body removing forceps. There is no danger for the patient. The inserting and the removing of the US take place under local anaesthesia of the bladder and cause no discomfort to the patient.- This treatise ist the first to report on the experiences of the regular use of the intraprostatic partial catheter (US) on a larger number of patients and it is the first to give a critical assessment. The present construction has been considerably improved compared to the first prototypes of 1978.(ABSTRACT TRUNCATED AT 250 WORDS)
