Significance of operative parameters on outcomes after transurethral resection of the prostate
Abstract
OBJECTIVE. The aim of this prospective study was to establish the influence of operative parameters on outcomes after transurethral resection of the prostate. MATERIALS AND METHODS. In this prospective case series study, 89 patients underwent transurethral resection of the prostate. The standardized protocol was used to investigate the impact of operative parameters (resected tissue weight, residual prostate weight, and residual prostatic weight ratio [total prostate volume - resected tissue weight / total prostate volume]) on outcomes after six months following transurethral resection of the prostate. The evaluation of treatment efficacy was done using the criteria of the Second International Consultation on Benign Prostatic Hyperplasia. All postoperative results were categorized as excellent, good, fair, or none. Treatment was considered effective when the postoperative results were excellent and good, and ineffective when results were fair and none. RESULTS. Treatment was effective for 85.4% and ineffective for 14.6% of the patients. The univariate analysis of operative parameters detected the residual prostatic weight ratio (cutoff value, 0.71; P<0.001; sensitivity, 0.62; specificity, 0.96; OR, 39.47) as the strongest independent predictor of ineffective outcome. Logistic regression analysis revealed two important parameters of unfavorable outcomes: residual prostatic weight ratio (cutoff value, 0.71; P<0.001; OR, 62.16) and residual prostate weight (cutoff value, 26.6…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 89 participants or records.
