Long term complications of the intraprostatic spiral. Case report.

A 76-year-old man had an intraprostatic spiral inserted to relieve bladder outlet obstruction that was caused by benign prostatic hypertrophy. After 30 months numerous complications had arisen including severe encrustations, urethral stricture, and sclerosis of the bladder neck. Regular replacement of the spiral or close monitoring of the development of encrustations seem necessary. The distal tip and the plating of the spiral require improvement.
