[Urodynamic study of obstructive uropathy due to benign prostatic hyperplasia].

Urodynamic examinations in patients with obstructive uropathy due to prostatic adenoma before and after prostatectomy were done over a 6-year-period (1981-1988) at the Department of Urology, Pula Medical Centre. In a comparative group of 30 healthy examinees and in 125 patients with obstructive uropathy as a result of benign prostatic hypertrophy, a maximal uroflowmetry and flow volume measurement were also performed. Control urodynamic studies were done 12 weeks after prostatectomy in 112 patients, and in 102 patients after 12 months. Preoperative and postoperative mean values of maximal uroflow were comparable. The aim of these urodynamic investigations is to estimate their value for a more complete and precise diagnosis of prostatism, and to determine, by urodynamic flow measurement before and after surgery, an outcome of prostatectomy in removal of prostatism symptoms and for urine flow improvement. Eighty-six patients underwent then open surgery, and 38 were operated transurethrally. The benign hypertrophy diagnosis was confirmed by histological analysis in all patients.
