Title: Urodynamic assessment for cases of benign prostatic hyperplasia associated with acute urinary retention
Abstract: Aim:Urodynamic and clinical parameters were analyzed in search of an outcome predictor after prostatectomy for cases of benign prostatic hyperplasia(BPH) associated with acute urinary retention (AUR). Methods: International Prostate Symptom Score, prostate volume, and urodynamic parameters were analyzed preoperatively and postoperatively in 26 cases of BPH associated with AUR. These parameters were compared between successful and failed treatment groups. Results: A voluntary detrusor contraction, with a mean maximal detrusor pressure of (6.62±3.57) kPa were noted in 24 patients. Five patients failed to void after transurethral vaporization of prostate (TUVP) and required catheterization. There were significant differences ( P 0.05) between 2 groups regarding age, maximal detrusor pressure, detrusor instability, detrusor compliance, and cystometric bladder capacity. Conclusion:For BPH patients with AUR, pressure flow studies undertaken within 4 weeks after retention are useful in predicting the surgical outcome. The increase of detrusor compliance and cystometric bladder capacity, absence of detrusor instability, and maximal detrusor pressure in the voiding phase lower than 1.96 kPa are possibly associated with a poor outcome after TUVP.
