Urodynamic studies in the surgical treatment of benign prostatic hyperplasia
OBJECTIVE: We compared the clinical and urodynamic outcome of men with lower urinary tract symptoms with and without previous urodynamic evaluation submitted to transurethral resection of the prostate.

| description | OBJECTIVE: We compared the clinical and urodynamic outcome of men with lower urinary tract symptoms with and without previous urodynamic evaluation submitted to transurethral resection of the prostate. MATERIALS AND METHODS: A prospective and randomized study was performed in 315 patients who underwent transurethral resection of the prostate. In 151 patients (group A) with a mean age of 63 years, transurethral resection of the prostate was performed without a prior urodynamic study, and group B, 164 patients with a mean age of 61 years, underwent a urodynamic study prior to surgical procedure. In group B, only obstructed patients were selected for surgery. All patients had I-PSS higher than 15 and underwent at least 2 uroflowmetry and flow was lower than 10 ml/sec. At 6-month follow up, patients in both groups underwent the I-PSS questionnaire and pressure / flow study. RESULTS: The symptomatology and uroflowmetry did not display different behavior between the groups. The mean postoperative score for group A was 8.87 + 3.27 and for group B was 9.32 + 3.14 (p = 0.22). The mean postoperative uroflow for group A was 17.0 + 2.1 mL/s and for group B was 16.6 + 2.2 mL/s (p = 0.15). Postoperative, in group A, 27 patients (17.8%) were obstructed and in group B, 16 patients (9.75%) were obstructed (p = 0.03). CONCLUSION: The study suggests that the previous urodynamic study is not the only factor related to the success of surgical outcome; and therefore, the symptomatology and uroflowmetry associated would be enough during the preoperative routine studies for BPH patients. |
