    Abstract:
    Twenty high risk patients with benign prostatic hyperplasia and urinary retention were treated by insertion of an intraprostatic spiral. The device was positioned under fluoroscopic guidance using a technique developed by us. The procedure required only local anaesthesia and successfully relieved the obstruction in all patients. At the six-month follow-up full continence had been achieved in 15 patients (75%). Three patients (15%) complained of mild stress incontinence but this was not severe enough to require removal and repositioning of the spiral. A 92-year-old patient reported severe incontinence despite correct positioning of the spiral. Removal of the spiral was necessary in one of the continent patients who was receiving anti-coagulant drugs because of sudden, severe macrohaematuria with subsequent acute urinary retention. The spiral became displaced and required repositioning in one patient. Median residual urine volume was constantly lower than 50 ml and the median maximal flow rate at six-month follow-up was 13.2 ml/s. Our long term follow-up study shows the effectiveness and safety of the prostatic spiral as an alternative treatment for selected patients with urinary retention caused by benign prostatic hyperplasia.
