Post Prostatectomy Prognostic Factors in Patients with Acute Urinary Retention due to Benign Prostatic Hyperplasia / 대한비뇨기과학회지

ABSTRACT

PURPOSE: Multiple parameters were preoperatively examined to determine if any could predict successful voiding after a prostatectomy in male patients presenting with acute urinary retention due to a benign prostatic hyperplasia. MATERIALS AND METHODS: A total of 93 men, between 58 and 87 years old (mean age 72.9 years), who presented with acute urinary retention were investigated pre and post-operatively with an urodynamic study, transrectal ultrasonography (TRUS) and a completed International Prostatic Symptom Score (IPSS). RESULTS: 3 months postoperatively, 6 patients (15.8%) with detrusor hyporeflexia or detrusor instability required clean intermittent catheterization to empty their bladders. All patients with a prostate volume over 40 gm were able to void without catheterization after the prostatectomy. The IPSS, age, residual urine, cystoscopic findings, preoperative creatinine and resected prostate weight were not predictive of voiding failure after a prostatectomy. CONCLUSIONS: The urodynamic study and TRUS findings are important predictors of the improvements in symptoms and flow rates for the acute urinary retention associated with a benign prostatic hyperplasia.
