Urodynamic analysis of non-improvement after prostatectomy / 中华医学杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To study the factors that affect the prognosis of the patients with benign prostatic hypertrophy (BPH) after prostatectomy.</p><p><b>METHODS</b>Using urodynamic methods, we studied 50 BPH patients with embarrassing outcomes after prostatectomy.</p><p><b>RESULTS</b>Detrusor instability (Dl) appeared in 20 (40%) patients. Twelve (24%) patients suffered from weak contractility of the detrusor and 18 (36%) patients had bladder outlet obstruction.</p><p><b>CONCLUSIONS</b>Dl, 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.</p>
