Risk factors of recurrence after transurethral resection of the prostate due to benign prostate hyperplasia / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVES</b>To review the clinic data of benign prostate hyperplasia (BPH) cases, and to find the risk factors of recurrence in post transurethral resection of the prostate (TURP) patients.</p><p><b>METHODS</b>From November 2002 to November 2007, 1471 cases were reviewed, including 41 patients of recurrence after TURP. Record the data include onset age, course of disease, age of surgery, LUTS, PSA, blood serum creatinine, size of the prostate in transabdomen ultrasonography, data of urodynamic examination, weight of resected tissue, persistence time of the resection, length of stay, score of inflammation of the pathologic sample, experience of the operator, routine blood examination, routine urine examination and so on. Statistical analysis was performed using univariate and multivariate unconditional Logistic regression analysis for evaluation of the data.</p><p><b>RESULTS</b>In the univariate analysis, onset age (t = 2.292, P = 0.086), PVR (t = 2.181, P = 0.03), size of the prostate in transabdomen ultrasonography (t = -1.987, P = 0.047), experience of the operator (Z = 10.13, P = 0.0015) and the symptom that bladder does not feel completely empty right after urinating (chi(2) = 9.240, P = 0.002) had statistical significance. In the multivariate unconditional Logistic regression analysis, Odds ratio (OR) of the factors were investigated, the symptom that bladder does not feel completely empty right after urinating (OR = 0.557), the score for inflammation (OR = 0.905) and experience of the operator (OR = 0.393) had statistical significance.</p><p><b>CONCLUSIONS</b>The risk factors for elevating the incidence of post-TURP recurrence are the lower score for inflammation, younger onset age, having the symptom that bladder does not feel completely empty right after urinating, bigger size of prostate in transabdomen ultrasonography, lower post void residual urine volume and poor experience of the operator.</p>
