Abstract
In order to evaluate the effect of intraprostatic spiral and subsequent transurethral prostatectomy (TURP) on obstructive benign prostatic hyperplasia, 9 men were evaluated with symptom scores and urodynamic studies at inclusion after 4 months of spiral treatment and 4 months after TURP. Six patients in a control group were evaluated at inclusion after an observation period of 4 months and 4 months after TURP. After treatment with spiral the symptom score decreased in 7 patients, increased in 1. and was unchanged in 1. After the observation period in the control group the symptom score decreased in 4 patients, increased in 1, and was unchanged in 1. After TURP the symptom score decreased even further in all patients, but one. After spiral treatment the urethral resistance decreased in 8 of 9 patients, but according to Abrams and Griffith's [(1979): Br J Urol 51:129–134] definition, only 2 were unobstructed. Five patients in the control group were unchanged obstructed after the observation period, while one was unobstructed. After TURP, the patients in both groups were all unobstructed. Intraprostatic spirals decrease the severity of symptoms and reduce the urethral resistance, but TURP in the same patient was much more effective.
