Monopolar TURP catheterised vs non catheterised

Comparison of outcomes between those patients undergoing monopolar transurethral resection of prostate for symptomatic benign prostatic hyperplasia with Foley catheterization preoperatively after at least one failed trial without catheter and those with moderate to severe bothersome lower urinary tract symptoms requiring surgical intervention with no Foley catheter preoperatively. Patient’s age, body mass index (BMI), American Society of Anesthesiologists’ classification (ASA), prostate volume, IPP, prostate specific antigen level (PSA) level, uroflowmetry findings, post-void residual (PVR) volume, International Prostate Symptom Score (IPSS). The operating time was calculated as time from the introduction of resectoscope till the placement of Foley catheter. Proportion of prostate resected was calculated as the volume resected weighed at the end of operation divided by the preoperative ultrasound determined prostate volume. Post-operative hemoglobin level was assessed at 24hr. Change in hemoglobin level was derived by subtracting the postoperative hemoglobin level at 24 hours from the preoperative level. Complications were classified as per modified Clavien classification system. Data analysis was done using the Statistical Package for Social Sciences Windows version 23. Baseline characteristics were compared using the Chi-square test for categorical variables and the student t-test/ Mann Whitney U test for continuous data. Anova was used to compare groups with various duration of preoperative catheterization. A p-value < 0.05 was considered statistically significant. Patient with preoperative catheterization had higher prostate volume, higher PSA level, higher volume of prostate resected, better postoperative subjective symptoms score and QOL score, longer duration of hospital stay and lower Qmax. T with similar complication rate. This data set can be used with SPSS software.

本数据集对比了两类患者的临床结局：一类为伴症状性良性前列腺增生（symptomatic benign prostatic hyperplasia）患者，术前留置Foley导尿管（Foley catheterization）且至少经1次试拔管失败；另一类为存在中重度困扰性下尿路症状、需接受手术干预且术前未留置Foley导尿管的患者。
研究收集的基线资料包括患者年龄、体重指数（body mass index, BMI）、美国麻醉医师协会分级（American Society of Anesthesiologists’ classification, ASA）、前列腺体积、IPP、前列腺特异性抗原（prostate specific antigen, PSA）水平、尿流率检查结果、残余尿（post-void residual, PVR）体积及国际前列腺症状评分（International Prostate Symptom Score, IPSS）。
手术时长定义为从置入前列腺电切镜至放置Foley导尿管的时间；前列腺切除比例为手术结束时称重的切除前列腺体积与术前超声测定前列腺体积的比值。
术后24小时检测血红蛋白水平，血红蛋白变化值为术前水平减去术后24小时检测值；并发症参照改良Clavien分类系统进行分级。
数据分析采用社会科学统计软件包Windows版23（Statistical Package for the Social Sciences Windows version 23，即SPSS 23）完成。分类变量的基线特征比较采用卡方检验，连续变量采用t检验/曼-惠特尼U检验；针对术前导尿管留置时长不同的组别，采用方差分析进行组间比较。以P值<0.05作为统计学显著性的判定标准。
研究结果显示，术前留置导尿管的患者前列腺体积更大、PSA水平更高、切除前列腺体积更多，术后主观症状评分与生活质量评分更优，住院时长更长，最大尿流率（Qmax）更低，且两组并发症发生率无显著差异。
本数据集可配合SPSS软件使用。
