Insertion of intraprostatic spiral(urospiral@) in high risk patients with benign prostatic hyperplasia

  • 1Department of Urology, Kang Nam General Hospital, Seoul, Korea.


Between January 1990 and March 1991, intraprostatic spiral was inserted with the use of local or spinal anesthesia via the traditional endoscopic technique in 16 patients with benign prostatic hyperplasia who had repeated urinary retention(12 patients, A group) and who had long term indwelling bladder catheter( 4 patient. B group) due to high operative risk. During 3 to 15 months of follow up after insertion, 11 patients(91.6%) of A group and 2 patient of B group showed free voiding without significant postvoid residual urine in all. Especially 7 patient of A group and 1 patient of B group showed satisfactory voiding with mean flow rate of more than 10ml/sec. our result suggest that in case of high operative risk, intraprostatic spiral is a favorable alternative to and indwelling catheter in patients with repeated urinary retention although less satisfactory results were obtained in those with long term indwelling catheter.
