Urodynamic analysis of non- improvement after prostatectomy

Objective To study the factors that affect the prognosis of the patients with benign prostatic hypertrophy (BPH) after prostatectomy Methods Using urodynamic methods, we studied 50 BPH patients with embarrassing outcomes after prostatectomy Results Detrusor instability (DI) appeared in 20 (40%) patients Twelve (24%) patients suffered from weak contractility of the detrusor and 18 (36%) patients had bladder outlet obstruction Conclusions DI, weak contractility of the detrusor and bladder outlet obstruction are the most frequent causes affecting the prognosis of BPH patients after prostatectomy Urodynamics may play a significant role in the identification of the causes of unsatisfied prognosis of BPH patients
