Comparison of clinical results between TUR-P and holmium laser enucleation of the prostate (HoLEP) based on the initial experience

OBJECTIVE: We compared the surgical results between holmium laser enucleation of the prostate (HoLEP) and transurethral resection of the prostate (TUR-P) for the treatment of men with benign prostatic hyperplasia (BPH). METHODS: A total of 87 patients with symptomatic BPH were analysed. HoLEP was performed on 46 men (mean age 68.2 +/- 7.5 years old) from December 2005 to February 2007, and TUR-P was performed on 41 men (mean age 69.2 +/- 7.3 years old) from April 2004 to March 2006. RESULTS: Both groups were comparable in terms of age, pre-operative IPSS, QOL index, urodynamic study results and prostate volume. During operation, decrease in hemoglobin was less in the HoLEP group than in the TUR-P group (1.15 +/- 1.2 vs 1.91 +/- 1.3 g/dl p < 0.05). The operation time was significantly longer in the HoLEP group than in the TUR-P group (161.9 +/- 65.0 vs. 118.3 +/- 36.9 minutes p < 0.001). Mean resected weight was 29.3 +/- 13.3 g (10-55) in the TUR-P group and 34.8 +/- 33.4 g (5-148) in the HoLEP group (p = 0.337). The catheterization period (52.1 +/- 29.6 vs. 115.2 +/- 27.5 hour p < 0.001) and hospital stay (6.6 +/- 2.3 vs. 9.4 +/- 2.2 days p < 0.001) were significantly shorter in the HoLEP group than in the TUR-P group. At follow up, Qmax, average flow rate and post void residual urine (PVR) in two groups improved significantly, and these parameters were not significantly different between the groups after 3 months. CONCLUSIONS: Both TUR-P and HoLEP were effective in relieving BOO. The estimated blood loss, a catheterization time and hospitalization were less or shorter in the HoLEP group. HoLEP may be a good alternative to the conventional transurethral electrocautery resection of the prostate for symptomatic BPH.     

Three-year outcome following holmium laser enucleation of the prostate combined with mechanical morcellation in 330 consecutive patients

OBJECTIVES: A prospective study to assess safety, efficacy, and medium-term durability of holmium laser enucleation of the prostate (HoLEP) combined with mechanical morcellation for the treatment of bladder outlet obstruction (BOO) due to benign prostate enlargement (BPE). METHODS: Between January 2000 and July 2003, 330 consecutive patients underwent HoLEP at our institution. All patients were pre-operatively assessed with transrectal ultrasound gland volume evaluation, maximum urinary flow rate (Q(max)), international prostate symptoms score (IPSS), and the single-question quality of life (QoL). Intra-, peri-, and postoperative parameters were evaluated and the patients were reassessed at 1-, 3-, 6-, 12-, 18-, 24-, and 36-mo follow-up with the same examinations. RESULTS: Patients' mean age was 66+/-8.1 yr; prostate volume was 62+/-34 cc. Enucleation time was 45.4+/-22.9 min and morcellation time 17.3+/-14 min, whilst resected weight was 40+/-27.5 g. Catheter time was 23+/-14.7h and hospital stay was 48+/-26 h. Mean serum hemoglobin and sodium did not drop significantly from baseline after the procedure (p=013). A significant improvement occurred in Q(max) (25.1+/-10.7 ml/s), IPSS (0.7+/-1.3), and QoL (0.2+/-0.5) at the 3-yr follow-up compared with baseline (p<0.05). Twenty-eight percent of patients complained of irritative urinary symptoms, typically self-limiting after 3 mo; transient stress incontinence was reported in 7.3% of patients. Nine patients (2.7%) had persistent BOO, requiring reoperation. CONCLUSIONS: HoLEP represents an effective and safe surgical intervention. The relief from BOO also proved to be durable after 3-yr follow-up. The present report adds to the evidence that HoLEP could be the standard "size-independent" surgical treatment for symptomatic BPE-related BOO.     

Transurethral holmium laser enucleation of the prostate versus transurethral electrocautery resection of the prostate: a randomized prospective trial in 200 patients

PURPOSE: Transurethral electrocautery resection (TURP) is generally regarded as the gold standard surgical treatment for bladder outflow obstruction due to benign prostatic hyperplasia despite its rather high morbidity. The high powered holmium:YAG laser can be used endoscopically to enucleate obstructing prostatic tissue in a relatively bloodless manner. The technique of transurethral holmium laser enucleation of the prostate (HoLEP) was compared to standard TURP for the surgical management of prostate adenomas in a randomized, prospective clinical trial. MATERIALS AND METHODS: A total of 200 urodynamically obstructed patients with a prostate of less than 100 gm on transrectal ultrasound were randomized to HoLEP or TURP. All patients were assessed preoperatively, and 1, 6 and 12 months postoperatively. Patient baseline characteristics, perioperative data and postoperative outcome were compared. All complications were noted. RESULTS: HoLEP was significantly superior to TURP in terms of catheter time, hospital stay and hemoglobin loss but operative time was longer. HoLEP and TURP resulted in a significant improvement in American Urological Association symptom scores, peak urinary flow rates and post-void residual urine volumes with symptoms scores and residual volume significantly better in the holmium group. Effects on continence and potency were similar in the 2 groups but adverse events were less frequent in the holmium group. CONCLUSIONS: HoLEP and TURP are highly effective procedures for removing obstructing prostatic adenomas. HoLEP resulted in significantly better micturition parameters and less perioperative morbidity.     

Is there a correlation between the outcome of transurethral resection of prostate and preoperative degree of bladder outlet obstruction?

To compare the impact of transurethral resection of prostate (TURP) on symptom scores and maximal flow rates (Qmax) in patients with equivocal bladder outlet obstruction (BOO) and definite BOO and to assess the relationship between the surgical outcomes and degree of preoperative BOO, we prospectively evaluated men with lower urinary tract symptoms and bladder outlet obstruction index (BOOI) greater than 20, who were refractory to conventional medical treatment and underwent TURP. Urodynamic evaluation, International Prostate Symptom Score (IPSS), uroflowmetry, post-void residual volume (PVR) check and transrectal ultrasound were performed. 20相似文献   

The 12‐year symptomatic outcome of transurethral resection of the prostate for patients with lower urinary tract symptoms suggestive of benign prostatic obstruction compared to the urodynamic findings before surgery

Study Type – Therapy (case series)
Level of Evidence 4

OBJECTIVE

To investigate whether bladder outlet obstruction (BOO), detrusor underactivity (DUA) and detrusor overactivity (DO) affect the long‐term outcome of transurethral resection of the prostate (TURP) for patients having lower urinary tract symptoms suggestive of benign prostatic obstruction.

PATIENTS AND METHODS

Of 92 patients who had TURP after a urodynamic study between 1995 and 1997, 43 (47%) were alive at the time of the survey in February 2008. Nine patients were excluded because of prostate cancer, neurological diseases and the impossibility of symptomatic examination. The International Prostate Symptom Score (IPSS) and quality‐of‐life (QoL) index were determined at baseline, 3 months, 3, 7 and 12 years after surgery for 34 patients.

RESULTS

Although the improved IPSS and QoL index at 3 months gradually deteriorated with time, patients at 12 years were still significantly better than those at baseline. The IPSS in patients without BOO deteriorated faster than in those with it, whereas neither DUA nor DO influenced the slope of change in IPSS. Regardless of the preoperative urodynamic findings, the QoL index remained improved for 12 years. Two‐thirds of patients with DUA but not BOO were satisfied with their urinary condition at 12 years.

CONCLUSION

The symptomatic improvement provided by TURP lasts for >10 years, although there is a gradual deterioration with time. The QoL index remained improved for 12 years regardless of the preoperative urodynamic findings.     

两种经尿道前列腺切除术的疗效比较

目的比较经尿道钬激光前列腺剜除术和经尿道前列腺电切术治疗良性前列腺增生症的效果。方法前列腺增生症患者123例随机分为两组（剜除术组60例、电切术组63例）,分别行HoLEP和TuRP,监测、记录两组患者术前、术中及术后的相关临床指标,进行分析、对比。结果术前两组一般情况比较差异无统计学意义（P〉0．05）。剜除术组手术时间、术中冲洗液量较电切术组多,但术中出血量、术后出血量、膀胱冲洗时间、尿管留置时间均小于电切术组。术后随访1～6个月,两组IPSS、Qmax较术前均明显改善（P〈0．01）;剜除术组发生尿道狭窄3例,尿失禁1例,无阳痿发生;电切术组发生尿道狭窄5例、尿失禁2例、阳痿1例,两组间手术并发症发生率差异无统计学意义（P〉0．05）。结论剜除术治疗前列腺增生症,效果可靠,与电切术相比,具有出血少,术后恢复快等优点,值得进一步推广应用。     

Holmium laser bladder neck incision versus holmium enucleation of the prostate as outpatient procedures for prostates less than 40 grams: a randomized trial

PURPOSE: Bladder neck incision (BNI) is a common, minimally invasive treatment option for bladder outflow obstruction in men with a small prostate. We compared BNI using the holmium:YAG laser to holmium enucleation of the prostate (HoLEP) in a prospective, randomized, urodynamically based trial. MATERIALS AND METHODS: A total of 40 patients with urodynamic obstruction (Schafer grade 2 or greater) and a prostate of 40 gm or greater on transrectal ultrasound (TRUS) were randomized equally to holmium laser BNI (HoBNI) or HoLEP as an outpatient procedure. The outcomes assessed were operative time, catheter time and hospital time. American Urological Association and quality of life scores, and maximal urinary flow rates were measured at baseline, and 1, 3, 6 and 12 months postoperatively, while pressure flow studies and TRUS volume measurement were performed at baseline and 6 months. RESULTS: The 2 groups were well matched for all variables at baseline. HoBNI was significantly more rapid to perform than HoLEP (p <0.001). Two patients (10%) in the HoBNI group required recatheterization compared with none in the HoLEP group. There was no significant difference in catheter time (22.9 vs 23.2 hours) or hospital time (12.3 vs 13.7 hours) between the groups. Five patients remained obstructed urodynamically at 6 months. All were in the HoBNI group and 4 of the 5 men had a prostate that was greater than 30 gm. Four of these patients required HoLEP for persistent lower urinary tract symptoms. In the remaining unoperated patients there were no significant differences in American Urological Association and quality of life scores or in the maximal urinary flow rate at each assessment. At 6 months detrusor pressure at maximal urinary flow was significantly lower (p <0.05) and TRUS volume was significantly smaller (p <0.001) in the HoLEP group There was significantly more early stress incontinence postoperatively in the HoLEP group but no bladder neck contractures were detected. CONCLUSIONS: Relief of obstruction was better after HoLEP and fewer patients required recatheterization or reoperation, although more reported early postoperative stress incontinence. Catheter time, hospital time and perioperative morbidity were similar. HoBNI and HoLEP are safe and feasible as outpatient procedures in patients with a small prostate but HoBNI is more rapid to perform.

经尿道钬激光前列腺剜除术与前列腺电切术近期疗效的对比分析

目的比较前列腺钬激光剜除术(holmium laser enucleation of the prostate,HoLEP)和前列腺电切术(transurethral resection of the prostate,TURP)治疗良性前列腺增生(benign prostatic hyplasia,BPH)的疗效及安全性。方法将2012年6月至2013年7月90例行腔内手术治疗的BPH患者随机分为2组,分别行前列腺钬激光剜除术(HoLEP)和经尿道前列腺电切术(TURP)。监测、记录2组患者围手术期和术后1、3、6个月复查指标,比较最大尿流率(maximum flow rate,Qmax)、国际前列腺症状评分(international prostate symptom score,IPSS)、生活质量评分(quality of life score,QOL)等变化并进行统计学分析,比较两种术式近期临床疗效。结果术前两组患者一般情况和国际前列腺症状评分、生活质量评分、最大尿流率、残余尿量测量以及前列腺重量比较差异无统计学意义(P0.05);HoLEP组较TURP组术中出血量、手术时间、低钠血症的发生率、膀胱冲洗时间、留管时间都较低(P0.01);术后1个月、3个月及6个月2组IPSS、QOL和Qmax均比术前有明显改善(P0.01);但2组间比较并无显著统计学意义(P0.05)。结论 HoLEP术与TURP术相比,近期手术效果相似,且手术安全性更好,可视为治疗BPH的较好新方法。     

经尿道前列腺切除术治疗晚期激素非依赖性前列腺癌可行性分析

目的:探讨经尿道前列腺切除术(TURP)在晚期前列腺癌并下尿路症状(LUTS)治疗中的作用。方法:对2004～2009年诊断为晚期前列腺癌合并LUTS的43例患者进行总结,分析TURP术前及术后3、12个月患者的IPSS评分、最大尿流率、以及疾病相关危险因素。结果:术后3个月,非雄激素依赖性前列腺癌患者的IPSS[(9.58±0.33)分]、最大尿流率[(8.96±0.47)ml/s]与术前[(19.60±0.41)分、(4.93±0.68)ml/s]存在显著差异(P<0.05)。随访12个月后IPSS[(15.73±0.66)分]、最大尿流率[(15.67±0.44)ml/s]与术前相比无显著性差异。多因素分析提示术前表现为急性尿潴留的患者术后预后相对较好,激素非依赖前列腺癌患者预后差。结论:TURP治疗晚期激素非依赖前列腺癌合并LUTS的患者,在短期内可以迅速降低IPSS评分,改善生活质量;远期效果不理想。同时,手术本身也可能带来相关并发症,降低患者生存质量。     

良性前列腺增生患者术前压力-流率测定的局限性

目的评估良性前列腺增生(BPH)患者术前行压力一流率测定的应用价值。方法BPH患者69例,根据尿动力学检查直线被动尿道阻力关系(PURR)图结果分为膀胱出口梗阻(BOO)组50例,无或可疑BOO组19例,术前行剩余尿、尿流率、膀胱有效容量和压力-流率测定,国际前列腺症状评分(IPSS)、生活质量评分(QOL)。术后3个月复查比较尿动力学指标变化。结果无或可疑BOO组和有BOO组平均Qmax分别为12.8 ml/s和7.6 ml/s,差异有统计学意义(P<0.01),2组年龄、膀胱最大容量、剩余尿、膀胱有效容量、IPSS和QOL等参数差异无统计学意义(P>0.05)。术后2组平均Qmax分别提高了7.2 ml/s和10.8 ml/s,BOO组Qmax提高幅度与无或可疑BOO组比较差异有统计学意义(P<0.05);2组IPSS和QOL与术前比较差异有统计学意义(P<0.05),IPSS和QOL的改善幅度2组间差异无统计学意义(P>0.05)。BOO组术前逼尿肌活动过度21例(42%),无或可疑BOO例组逼尿肌活动过度7例(37%)。BOO组和无或可疑BOO组术后3个月IPSS和QOL等参数改善不明显分别有15例(30%)和6例(32%)。结论压力-流率测定有无BOO,对大部分BPH患者仍有预测疗效的作用;但术前膀胱有效容量大小以及逼尿肌活动过度等因素影响了手术疗效。部分伴严重下尿路症状(LUTS)的BPH患者无BOO,手术疗效满意。术前BPH患者压力-流率测定应有选择应用,结果分析个体化。     

Holmium laser enucleation versus transurethral resection of the prostate: 3-year follow-up results of a randomized clinical trial

OBJECTIVES: To report 3-yr follow-up results of a randomised clinical trial comparing holmium laser enucleation of the prostate (HoLEP) with transurethral resection of the prostate (TURP). METHODS: A total of 200 patients with urodynamic obstruction and a prostate volume of less than 100 cc were prospectively randomised and assigned to HoLEP or TURP. All patients were assessed preoperatively and followed at 1, 6, 12, 18, 24, and 36 mo postoperatively. American Urological Association Symptom Score (AUA SS), maximum flow rate (Q(max)), and postvoid residual (PVR) [urine] volume were obtained at each follow-up. Perioperative data and postoperative outcome were compared. All complications were recorded. RESULTS: AUA SS were significantly better 2 yr postoperatively in the HoLEP group (1.7 vs. 3.9, p<0.0001) and similar at 3 yr (2.7 vs. 3.3, p=0.17). PVR volume was significantly better 2 yr (5.6 vs. 19.9 ml, p<0.001) and 3 yr (8.4 vs. 20.2 ml, p=0.012) postoperatively in HoLEP patients. Q(max) was similar in the HoLEP and TURP groups at 2 yr (28.0 vs. 29.1 ml/s, p=0.83) and at 3 yr (29.0 vs. 27.5 ml/s, p=0.41) postoperatively. Late complications consisted of urethral strictures, bladder-neck contractures, and BPH recurrence; reoperation rates were 7.2% in the HoLEP and 6.6% in the TURP group (p=1.0). CONCLUSIONS: After 2 and 3 yr of follow-up, HoLEP micturition outcomes compare favourably with TURP. Late complications are equally low. HoLEP may be a real alternative to TURP.     

Comparison of photoselective vaporization and standard transurethral resection of the prostate on urodynamics in patients with benign prostatic hyperplasia

Objectives:   To compare photoselective vaporization of the prostate (PVP) and transurethral resection of the prostate (TURP) in patients with benign prostatic hyperplasia.
Methods:   Patients were enrolled in a prospective non-randomized trial and underwent PVP ( n  = 78) and TURP ( n  = 51). Primary outcome variables included: International Prostate Symptom Score, quality-of-life score, urinary peak flow and post-void residual urine volume at 3, 6 and 12 months postoperatively. Secondary outcomes were urodynamic variables, including the index of bladder outlet obstruction (BOO) and detrusor contractility.
Results:   Improvement in all outcome variables after PVP was comparable to that after TURP within 12 months. Outcome based on urodynamic parameters was also similar. Pre/post median value of the BOO index was 63/2 in the PVP group and 61/5 in the TURP group. Pre/post rate of detrusor overactivity was 49%/27% in the PVP and 53%/29% in the TURP group. There was minimal change in detrusor contractility. Overall, morbidity was comparable in the two groups.
Conclusions:   The 12-month outcome after PVP is similar to that of TURP with an effective relief from BOO and detrusor overactivity and minimal change in detrusor contractility.     

TURP and low-energy TUMT treatment in men with LUTS suggestive of bladder outlet obstruction selected by means of pressure-flow studies: 8-year follow-up

AIMS: To evaluate the long-term outcome of transurethral resection of the prostate (TURP) and transurethral microwave thermotherapy (TUMT) in men with symptomatic benign prostatic hyperplasia (BPH), when allocation to the treatment-group was based on urodynamic diagnosis of bladder outlet obstruction (BOO). METHODS: A total of 231 elderly men with symptomatic BPH were treated either by TURP or by low-energy TUMT. A pressure-flow study was performed to detect the obstruction and to help in the selection of the two treatments. The patients were examined at baseline then checked again after 2 and 8 years. RESULTS: At 2 years of follow-up there was a significant improvement for both IPSS and QoL (P < 0.0001) in both groups of treatment. This was accompanied by a significant improvement (P < 0.0001) in the maximum flow rate from 10.0 (5.8) to 16.4 (7.6) in the TURP group and from 12.1 (5.2) to 14.9 (5.7) in the TUMT group. These findings persisted at 8 years, they were, however, more pronounced after TURP. The overall retreatment rate reached a value of 11% in the TURP group and 27% in the TUMT group, respectively. At the follow-up, 95% of the patients who underwent TURP and 70% of the patients treated by TUMT claimed to be satisfied with that choice. CONCLUSIONS: With durable symptomatic improvement and lowest retreatment rate, TURP still presents a standard treatment option for patients with severe BOO. Low-energy TUMT has sufficiently relieved patients' symptoms and can be offered to less obstructed patients as an alternative.     

逼尿肌收缩压测定在BPH患者术后疗效评估中的意义

目的 探讨逼尿肌收缩压测定在BPH患者术后疗效评估中的应用价值.方法 BPH患者109例.年龄62～83岁,平均71岁.均行尿动力学检查,明确诊断BOO,排除神经、内分泌以及其他系统疾病因素.根据逼尿肌收缩情况分为2组:Ⅰ组为逼尿肌亢进型61例,逼尿肌收缩压≥40 cm H2O(1 cm H2O=0.098 kPa),单纯行TURP或开放手术;Ⅱ组为逼尿肌无力型48例,逼尿肌收缩压≤20 cm H2O,同期行TURP和膀胱造瘘术,术后持续开放造瘘管至少2周.统计学比较2组患者术后1、3个月逼尿肌收缩压、Qmax和残余尿等参数.结果 2组患者术前最大逼尿肌收缩压分别为(78.4±37.0)、(19.2±5.4)cm H2O,Qmax分别为(7.6±2.2)、(2.5±1.1)ml/s,组间差异均有统计学意义(P＜0.05);术后1个月Qmax分别为(17.4±2.9)、(12.5±2.0)ml/s,组间差异有统计学意义(P＜0.05);术后3个月Qmax分别为(18.3±2.8)、(15.2±1.8)ml/s,组间差异无统计学意义(P＞0.05).结论 BPH患者BOO解除后,收缩乏力状况可以逐渐恢复,Qmax能获得改善,对合并逼尿肌收缩无力患者积极手术解除梗阻,可促进逼尿肌功能恢复.

Abstract：

Objective To study the value of the preoperative detrusor contractility to the outcome assessment of prostatectomy for benign prostatic hyperplasia (BPH).Methods A total of 109 patients with BPH were analyzed.Their ages ranged from 62 to 83 years with a mean of 71 years.All patients underwent urodynamic study to confirm a diagnosis of BOO preoperatively.Further more, their BOO was not caused by nervous, endocrine or other diseases.Pateints were divided into two groups based on maximum detrusor contractility.Group Ⅰ (n =61, BPH with maximum detrusor contractility ≥ 40 cm H2O, 1cm H2O =0.098 kPa) underwent TURP or open surgery, respectively.Group Ⅱ (n =48, BPH with maximum detrusor contractility ≤ 20 cm H2O ) underwent TURP and suprapubic punctural cystostomy simultaneously,the bladder fistula was kept open continuously for at least two weeks postoperatively.The difference in outcome between the two grous was assessed by using urodynamic parameters including maximum detrusor contractility, Qmax and residual urine at one and three months postoperatively respectively.Student's t-test was used to compare the result for normally distributed data and Wilcoxon's signed-ranks test for skewed data in this study.Results There was significant difference in preoperative maximum contractility, Qmax between group Ⅰand groupⅡ (78.4 ±37.0 cm H2O) vs (19.2 ±5.4 cm H2O)(P＜0.01), (7.6±2.2 ml/s) vs (2.5 ± 1.1 ) ml/s (P ＜ 0.05) respectively.Although there was significant difference at one month postoperatively in Qmax (17.4 ±2.9)ml/s vs (12.5 ±2.0)ml/s (P＜0.05), no significant difference was found in Qmax between the two groups after three months ( 18.3 ±2.8 ml/s) vs ( 15.2 ± 1.8)ml/s (P ＞ 0.05).Conclusions The Qmax may improve and the impaired detrusor recovered gradually after the BOO was removed.Performing an operation on patients with BOO accompanied with detrusor underactivity may be useful to recover detrusor contractility.     

钬激光剜除术和经尿道前列腺切除术治疗症状性前列腺梗阻的meta分析

目的比较钬激光前列腺剜除术（HoLEP）与经尿道前列腺电切术（TURP）两种术式的优缺点。方法检索Medline，Embase及Cochrane图书馆报道的HoLEP和TURP治疗症状性前列腺尿路梗阻的随机对照研究（RCTs）。主要观察指标包括最大尿流率（Qmax）、残余尿量、症状评分及生活质量评分，次要观察指标包括手术时间、住院时间、失血量、留置导尿管时间及并发症。结果6—12个月的术后随访中，Qmax在HoLEP和TURP治疗两组间没有统计学差异。但HoLEP术中失血量更少，留置导尿管时间及住院时间更短；而TURP手术时间小于HoLEP。两者在术后尿道狭窄、尿失禁、输血率及再次手术的发生率无统计学差异。结论HoLEP和TURP改善患者Qmax疗效相当。HoLEP手术时间比TURP长，但HoLEP失血量少，留置导尿管时间及住院时间较TURP短。术后各种并发症的发生率两者没有差别。     

Change in serum prostate specific antigen concentration after holmium laser enucleation of the prostate: a marker for completeness of adenoma resection?

BACKGROUND AND PURPOSE: Holmium laser enucleation of the prostate (HoLEP) is a well-established technique for the treatment of benign prostatic hyperplasia (BPH). To date, changes in serum prostate specific antigen (PSA) after HoLEP have not been published. We hypothesized that HoLEP produces a diminution in PSA similar to that produced by the gold-standard therapies for BPH. To test this hypothesis, we have examined PSA data before and after HoLEP from two institutions performing high volumes of this procedure. PATIENTS AND METHODS: Between August 1998 and September 2004, 509 HoLEPs were performed at two institutions for which complete PSA data were available. Preoperative demographic and transrectal ultrasonography (TRUS) volume measurements were recorded; postoperative pathology and TRUS volume were obtained. Change in PSA as a function of the weight of prostate resected and the relation of preoperative TRUS volume to PSA was determined. RESULTS: The average weight of adenoma resected was 49.8 g (range 5-300 g) in the McGill group and 90.4 g (range 7.9-312 g) in the Methodist Hospital group. The mean decrease in PSA was 81.7% in the McGill group (range 6.0-1.1 ng/mL; P < 0.0001) and 86.0% in the Methodist Hospital group (range 8.6-1.2 ng/mL; P < 0.0001). Log transformed preoperative PSA correlated well with TRUS volume (r = 0.45), as did the weight of adenoma resected with absolute change in PSA (r = 0.38). The TRUS volume decreased significantly, from 111.9 cc to 26.5 cc, in the Methodist Hospital group (P < 0.0001). CONCLUSION: The HoLEP procedure produces a significant diminution in PSA that correlates well with the weight of adenoma resected. Measurement of PSA may be a useful tool for the objective assessment of ablative therapies for BPH, as the reduction in PSA corresponds well with the amount of adenoma removed.     

The 2-year symptomatic and urodynamic results of a prospective randomized trial of interstitial radiofrequency therapy vs transurethral resection of the prostate

OBJECTIVE: To assess the 2-year symptomatic and urodynamic results of a prospective randomized trial of interstitial radiofrequency therapy of the prostate (IRFT) vs transurethral resection of the prostate (TURP). PATIENTS AND METHODS: Patients with lower urinary tract symptoms (LUTS) and urodynamic evidence of bladder outlet obstruction (BOO) were randomized to undergo IRFT or TURP and were followed up using the International Prostate Symptom Score (IPSS) and urodynamic assessment for 2 years. RESULTS: At 2 years there was a clinically relevant reduction in the IPSS in the IRFT (20 to 9) and TURP groups (22 to 4). There was also a statistically significant reduction in the detrusor pressure at maximum urinary flow in both groups, but the reduction in the IRFT group was probably not sufficient to explain the observed symptomatic improvements solely from a reduction in BOO. CONCLUSION: IRFT can produce a sustained improvement in LUTS for at least 2 years. However, such improvements are unlikely to be entirely the result of a reduction in BOO. The effects of radiofrequency energy may, at least partly, be independent of any thermal effect and depend instead on neuromodulation of lower urinary tract nerves.     

Safety and efficacy of transurethral resection of prostate glands up to 150 ml: a prospective comparative study with 1 year of followup

PURPOSE: We investigated the safety and efficacy of transurethral resection of the prostate (TURP) for prostate glands between 70 and 150 ml. MATERIALS AND METHODS: We prospectively evaluated 113 patients treated with TURP for benign prostatic hyperplasia. A total of 57 patients with a prostate volume of less than 70 ml were assigned to group 1, while 56 with a prostate volume of between 70 and 150 ml were assigned to group 2. Preoperative parameters considered in each patient were prostate volume, International Prostate Symptom Score (I-PSS), urinary flow rate measurement (Qmax) and post-void residual urine volume (PVR). Operative time, resected tissue weight and all complications were recorded. All patients were evaluated 3 months and 1 year postoperatively. Preoperative, perioperative and postoperative data on the 2 groups were compared. RESULTS: Each group achieved significant improvement in I-PSS, Qmax and PVR. Operative time was significantly longer in group 2 but the complication rate was similar in the 2 groups. Group 2 resulted in better improvements in Qmax and I-PSS. At 1 year of followup PVR was significantly lower in group 1 than in group 2. Multivariate analysis revealed that only age was a significant independent predictor of complications, and only age and initial Qmax were independent predictive variables of outcome. CONCLUSIONS: TURP for large prostate glands is a safe procedure without showing a different complication rate compared with TURP for recommended volumes. Patients with a baseline prostate volume of greater than 70 ml seem to achieve better improvement in obstruction and symptoms.
