Does perioperative outcome of transurethral holmium laser enucleation of the prostate depend on prostate size?

BACKGROUND AND PURPOSE: In conventional transurethral resection of the prostate (TURP), perioperative morbidity resulting from causes such as blood loss and TUR syndrome increases with prostate size. Therefore, TURP is restricted to small and medium-sized glands. The present study aimed to find out whether perioperative parameters of holmium laser enucleation of the prostate (HoLEP) other than operation time and weight of resected tissue were dependent on prostate size. PATIENTS AND METHODS: A total of 384 patients were treated with HoLEP (holmium:YAG laser, 2.0 J, 40 or 50 Hz, 80 or 100 W, 550-nm bare fiber) for acute removal of obstructing benign hyperplastic tissue. Among them, 111 patients (28.9%) had prostates of <40 g (group 1), 152 (39.6%) had prostates of 40 to 79 g (group 2), and 121 (31.5%) had prostates of >/=80 g (range 80-260) (group 3). The perioperative outcomes of the three groups were compared. A total of 346 patients completed the 1-month postoperative assessment. RESULTS: The mean prostate sizes were 31.8 g, 56 g, and 98.7 g for groups 1, 2, and 3 (P<0.0001 group 1 v group 2 v group 3). The mean resected tissue weight was 19.5 g v 34.4 g (P= 0.009) v 70.1 g (range 50-220) (P< 0.0001). The mean operation time was 64.3 v 84.2 (P= 0.009) v 118.4 minutes (P< 0.0001). The mean hemoglobin loss was 0.9 v 1.2 (NS) v 1.9 g/dL (P< 0.001). The overall correlation between hemoglobin loss and prostate size in all patients was very weak (r = 0.229) and just exceeded the level of significance (r = 0.2). In all three groups, the median postoperative catheter time was 1 day, and the median postoperative hospital stay was 2 days. The HoLEP resulted in an immediate and significant improvement of American Urological Association Symptom Scores, peak urinary flow rates, and postvoiding residual urine volumes (P< 0.0001) 1 month after the operation, without significant differences between the groups. The rate of complications was similar in all three groups. None of the patients needed blood transfusions. There were no perioperative deaths. CONCLUSION: In HoLEP, perioperative morbidity and postoperative micturition improvement do not depend on prostate size. Therefore, in contrast to TURP, HoLEP is equally suitable for small, medium-size, and large prostate glands.     

Holmium laser enucleation of the prostate: comparison of outcomes according to prostate size in 97 Japanese patients

PURPOSE: To review the outcomes associated with holmium laser enucleation of the prostate (HoLEP) to identify the efficacy and safety in relation to the prostate size in subjects with symptomatic benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: A retrospective review was conducted of the data from 97 patients who had undergone HoLEP combined with mechanical morcellation. All patients completed both the preoperative and the 6-month postoperative assessment. The morbidity and improvement in the outcome variables were compared in groups classified according to the baseline prostate volume: <50 cm3 (group 1), >or=50 cm3-<100 cm3 (group 2), and >or=100 cm3 (group 3). RESULTS: The peak urinary flow rate (Qmax), postvoiding residual urine volume (PVR), International Prostate Symptom Score (IPSS) and quality of life (QoL) score all improved significantly after HoLEP, and no significant differences were observed among the groups. The mean total operation times were 70.3, 99.1, and 155.5 minutes for groups 1, 2, and 3, respectively (P < 0.0001 group 1 v group 2 v group 3). The mean times required to complete the enucleation and morcellation were 44.7 v 66.5 v 107.3 minutes (P < 0.0001) and 8.6 v 10.9 v 23.8 minutes (P < 0.0001), respectively. The efficacy for tissue enucleation and morcellation was 0.44 v 0.57 v 0.75 g/min (P < 0.0001) and 2.5 v 3.3 g/min (P = 0.016) v 3.2 g/min (P = 0.035). The mean hemoglobin loss after HoLEP was greater in group 3 than in group 1 (P = 0.036), but it was still low (1.8 g/dL). Major complications included bladder-muscle injury in one patient in group 2 and one in group 3 and long-lasting urinary incontinence in one patient in group 1 and one in group 2 (2.1%). No blood transfusion or transurethral resection syndrome was observed in any of the groups. CONCLUSIONS: Holmium laser enucleation is an effective treatment for symptomatic BPH independent of prostate size.

New Advances in Benign Prostatic Hyperplasia: Laser Therapy

Throughout the past decade, numerous techniques for the treatment of benign prostatic hyperplasia have emerged. Laser therapy, in particular, has gained widespread popularity among urologists. Since its inception in 1996, holmium laser enucleation of the prostate (HoLEP) has been evaluated rigorously in the treatment of glands of all sizes. HoLEP has produced superior relief of bladder outlet obstruction as compared to transurethral resection of the prostate based on urodynamics, and has proved equally as effective as open prostatectomy, for the management of very large glands (>100 cc), with lower morbidity. In addition to HoLEP, several newer but less well-studied laser techniques currently are available. These include photoselective laser vaporization utilizing the potassium-titanyl-phosphate (KTP or “green light”) laser, thulium laser enucleation, and high-power diode laser vaporization. This report reviews the most current literature on laser therapies utilized in the treatment of benign prostatic hyperplasia with regards to safety, outcome, efficiency, and long-term durability.

Holmium laser enucleation of the prostate (HoLEP): long-term results, reoperation rate, and possible impact of the learning curve

OBJECTIVES: To evaluate long-term outcomes and reoperation rate of holmium laser enucleation of the prostate (HoLEP) for patients with symptomatic enlarged prostate, including patients who were operated during the learning curve. METHODS: A retrospective analysis of 118 patients who underwent HoLEP between March 1998 and February 2001 at our institution. This analysis represented our initial experience with the technique reflecting our learning curve. The voiding outcome parameters, operative duration time, enucleation time, morcellation time, eucleated tissue weight, catheterization time, hospital stay, and complications were recorded. RESULTS: The mean patient age was 76.5 yr (range: 59-93) and the mean preoperative prostate volume was 59.3 cc (range: 20-172). The mean follow-up period was 49.4+/-28.1 mo. The mean catheter time and hospital stay was 1.3 and 1.5 d, respectively. Seventy-eight percent of the patients were discharged home within 24h after surgery. For the patients (n=26) who had objective data at 6 yr postoperatively, mean maximum flow rate increased from 6.3 to 16.2ml/s and mean postvoid residual urine decreased from 232 to 41.2ml (p<0.0001). Mean International Prostate Symptom Score improved from 17.3 to 5.6 (p<0.0001). Bladder-neck contracture and urethral stricture developed in 0.8% and 1.7% of patients, respectively. The reoperation rate for recurrent benign prostatic hyperplasia obstruction was 4.2%. CONCLUSIONS: HoLEP represents a safe and effective treatment for patients with symptomatic enlarged prostate. The improvement in outcome parameters is durable, and the late complications and reoperation rate are very low.     

Laser treatment of benign prostatic hyperplasia

To evaluate the role of lasers that allow acute removal of obstructing tissue in the surgical treatment of benign prostatic hyperplasia (BPH). A MEDLINE search over the last 6 years focused on randomized trials, large case series and review articles. A total of more than 4,000 patients were analyzed with respect to the morbidity and outcome, and the advantages and disadvantages of the various lasers. Laser treatment of BPH has evolved from coagulation to enucleation. Blood loss is significantly reduced as compared to transurethral resection and open prostatectomy. Ablative/vaporizing techniques have recently become popular again with the marketing of new high-powered 80 W potassium-titanyl-phosphate (KTP) and 100 W holmium lasers. Vaporization immediately removes obstructing tissue, but tissue specimen cannot be obtained. KTP short-term results are promising, but long-term results and randomized trials are lacking. Postoperative volume reduction is less than with holmium laser enucleation of the prostate (HoLEP), and the KTP laser can be used for BPH treatment only. HoLEP allows whole lobes of the prostate to be removed. Prostates of all sizes can be operated on. It is at least as safe and effective as TURP and open prostatectomy, with significantly lower morbidity, as shown by several well-designed randomized clinical trials. It provides specimen for histological evaluation. In addition, the holmium laser can be used for the endourological treatment of stones, strictures and tumors. HoLEP appears to be a size-independent new “gold standard” in the surgical treatment of BPH.     

Holmium laser enucleation for prostate adenoma greater than 100 gm.: comparison to open prostatectomy

PURPOSE: Options for treatment of large (greater than 100 gm.) prostatic adenomas have until now been limited to open surgery or transurethral resection by skilled resectionists. Considerable blood loss, morbidity, extended hospital stay and prolonged recovery occur with open surgery for large prostatic adenomas. Endoscopic surgery for benign prostatic hyperplasia has evolved during the last decade to offer the patient and surgeon significant advantages of transurethral removal of prostatic adenomas. Holmium laser enucleation of the prostate with transurethral tissue morcellation provides significant reductions in morbidity, bleeding and hospital stay for patients with large prostate adenomas. MATERIALS AND METHODS: A retrospective review of data on 10 cases of holmium laser enucleation and 10 open prostatectomies for greater than 100 gm. prostatic adenomas was performed from 1998 to 1999 at our institution. Patient demographics, indication for surgery, preoperative and postoperative American Urological Association (AUA) symptom scores, operating time, serum hemoglobin, resected prostatic weight, pathological diagnosis, length of stay and complications were compared. RESULTS: Patient age, indications for surgery (retention, failed medical therapy, high post-void residual, bladder calculi, bladder diverticula and azotemia) and preoperative AUA symptom scores were similar in both groups. Postoperative AUA symptom scores were significantly decreased (p <0.004) in both groups. Operating times were not significantly different. Serum sodium was unchanged by holmium laser enucleation (not significant), and postoperative hemoglobin was not significantly reduced in the holmium laser enucleation group but decreased significantly in the open prostatectomy group (mean decrease 2.9 +/- 0.7 gm., p = 0.0003). Resected weight was greater in the holmium laser enucleation group (151 versus 106 gm., p = 0.07). Length of stay was significantly shorter in the holmium laser enucleation group (2.1 versus 6.1 days, p <0.001). Complications in the holmium laser enucleation group included stress urinary incontinence in 4 cases, prostatic perforation in 1 and urinary retention in 1. No patient treated with holmium laser enucleation was discharged home with an indwelling catheter. Complications in the open prostatectomy group included bladder neck contractures in 2 cases, stress incontinence in 1 and urge incontinence in 1. All patients treated with open prostatectomy were discharged home with an indwelling catheter. CONCLUSIONS: Holmium laser enucleation is an effective, safe procedure for large prostatic adenomas with significantly lower morbidity, catheterization duration and length of stay. Performing holmium laser enucleation for large adenomas requires experience. Stress incontinence was seen frequently with laser but was short-term and self-limited. Holmium laser enucleation is a new procedure, and as experience and expertise increase, it may become an attractive alternative to open prostatectomy for patients with large prostate adenomas.     

Holmium laser enucleation for large (greater than 100 mL) prostate glands

BACKGROUND: To evaluate the holmium laser enucleation of the prostate (HoLEP) using the transurethral soft tissue morcellator (TUSTM), as a primary surgical treatment for symptomatic benign prostatic hyperplasia (BPH) with prostate glands > 100 mL. METHODS: Eighteen patients with preoperative prostate volumes > 100 mL underwent the HoLEP procedure. The criteria for surgery were determined by a preoperative International Prostate Symptom Score (IPSS), a prior failure of medical therapy, and urinary retention. RESULTS: The mean preoperative IPSS and prostate gland size were 13.8 and 142.3 mL, respectively. The total energy used by the laser was 288.4 kJ. The mean catheter time was 23.8 h and, perioperatively, no patients had electrolyte abnormalities or required blood transfusions. The 3-week postoperative IPSS was 2.8, with minimum long-term complications. CONCLUSIONS: Holmium laser enucleation of the prostate with TUSTM is a safe and effective alternative to open prostatic surgery for glands > 100 mL.     

Holmium laser enucleation of the prostate (HoLEP): the endourologic alternative to open prostatectomy

OBJECTIVE: To evaluate HoLEP for patients with enlarged prostate (traditionally treated by open prostatectomy) with long-term follow-up. METHODS: A retrospective analysis of 225 consecutive patients presenting with lower urinary symptoms secondary to benign prostatic hyperplasia with large prostate (>80 cc) who underwent HoLEP. Enucleation time, morcellation time, enucleated tissue weight, catheterization time, hospital stay, voiding outcome parameters, and complications were recorded. RESULTS: Mean preoperative prostate volume was 126+/-45.1 cc (range 80-351, median 111.2 cc), and resected tissue weight was 86.5 g. Mean follow-up was 31+/-12 months (median 24 months). Mean catheter time and hospital stay were 1.3 and 1.2 days, respectively. Patient symptom scores and peak flow rates were significantly improved immediately after surgery and continued to improve during subsequent follow up. Two patients required intraoperative blood transfusion, and a third patient needed blood transfusion in the early postoperative period for persistent hematuria. Bladder neck contracture and urethral stricture developed in 0.4% and 1.3%, respectively. CONCLUSIONS: HoLEP represents a safe and effective treatment for patients with symptomatic large prostates. It offers patients who traditionally required open prostatectomy the alternative of being treated endoscopically with minimal blood loss, short catheterization time and hospital stay.

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.     

Current role of lasers in the treatment of benign prostatic hyperplasia (BPH)

OBJECTIVE: Evaluate the current role of lasers in the treatment of benign prostatic hyperplasia (BPH). METHODS: The results of a MEDLINE search for randomised trials and case series of the last 5 yr and published review articles were analysed for the safety and efficacy of neodymium:yttrium aluminum garnet (Nd:YAG), potassium-titanyl-phosphate (KTP), and holmium (Ho):YAG laser prostatectomy. The analysis includes 12 reports on randomised clinical trials, 2 comparative studies, 10 review articles, and a total of >5000 patients. RESULTS: Laser treatment of BPH has evolved from coagulation to enucleation. Blood loss is significantly reduced compared with transurethral resection and open prostatectomy. Visual laser ablation of the prostate and interstitial laser coagulation cause coagulative necrosis with secondary ablation. Long postoperative catheterisation, unpredictable outcomes, and high reoperation rates have restricted the use of these techniques. Ablative/vaporising techniques have become popular again with the marketing of new high-powered 80-W KTP and 100-W Ho lasers. Vaporisation immediately removes obstructing tissue. Short-term results are promising, but large series, long-term results, and randomised trials are lacking. Holmium laser enucleation (HoLEP) allows whole lobes of the prostate to be removed, mimicking the action of the index finger in open prostatectomy. Prostates of all sizes can be operated on. It is at least as safe and effective as transurethral resection of the prostate and open prostatectomy, with significantly lower morbidity. It is the only laser procedure that provides a specimen for histologic evaluation. CONCLUSIONS: HoLEP appears to be a size-independent new "gold standard" in the surgical treatment of BPH.     

Transurethrale Laserenukleation der Prostata mit dem Holmiumlaser

PURPOSE: To evaluate the efficacy and safety of an intermediate power (50 W) holmium:YAG laser system for transurethral enucleation of the prostate (TULP) with the use of a new mechanical morcellator. Our results are compared with the results of high-powered holmium laser enucleation (HoLEP) presented in the literature. MATERIAL AND METHODS: From December 2003 to January 2008, 129 patients with benign prostatic hyperplasia were treated by TULP. In 45 cases (group A; 2.0, 12 Hz) we used a bipolar resectoscope (VISTA/ACMI) for morcellation, whereas after that morcellation was accomplished with a modified endoscopic shaver (Wolf). Thirty-nine patients were treated using 25 W (group B; 2.0 J, 12 Hz), and 45 patients were treated using 40 W (group C; 2.2 J 18 Hz), who were compared with 45 matched-pair patients who received transurethral resection of the prostate (TURP; group D). Finally, the literature on HoLEP was reviewed. RESULTS: Bipolar morcellation significantly prolonged the operating time (135 vs. 131 vs. 96 min). The morcellation speed averaged 2.8 (range 1.3-5.2) g/min with no complications. The resection speed (retrieval rate) of 40-W TULP was comparable to that for TURP (0.71 vs. 0.76 g/min). The transfusion rate was lower than for TURP (8% vs. 12%), with a smaller Hb difference (3.1 vs. 3.8 mg/dl). Catheter times (3.4 vs. 4.1 days) were similar; however, hospital stay was significantly shorter after TULP (5.2 vs. 6.8 days). The complication rate was significantly lower (6.6% vs. 13.3%). The efficacy of HoLEP significantly improved with introduction of the morcellator: Resection speed increased from 0.34-0.61 g/min to 0.48-0.82 g/min. HoLEP was better than 40-W TULP regarding transfusion rate (0-4% vs. 8%) and catheter time (1.1-1.5 vs. 3.4 days). Complications and functional results were similar. CONCLUSION[UBERSCHRIFT]: The intermediate-power 50-W holmium laser together with the new morcellator enable safe transurethral enucleation of the prostate. As with HoLEP, the procedure has a significant learning curve. The retrieval times of TULP are similar to those for HoLEP, but the risk of bleeding is higher. New modifications (i.e., thullium laser) will further improve the technique of laser enucleation.     

Nerve-sparing radical retropubic prostatectomy in patients previously submitted to holmium laser enucleation of the prostate for bladder outlet obstruction due to benign prostatic enlargement

OBJECTIVES: To evaluate the feasibility and safety of nerve-sparing radical retropubic prostatectomy (NSRRP) for localised prostate cancer after holmium laser enucleation of the prostate (HoLEP) for bladder outlet obstruction due to benign prostatic enlargement (BPE). METHODS: Fifteen consecutive patients with prostate cancer following HoLEP underwent NSRRP. They were matched with an equal number of patients who also underwent NSRRP following transurethral resection of the prostate (TURP group) or open prostatectomy (OP group). Patients were preoperatively assessed with validated questionnaires (International Prostate Symptom Score [IPSS] and International Index of Erectile Function-Erectile Function [IIEF-EF]). Intraoperative, perioperative, and follow-up functional data according to validated questionnaires (IPSS, IIEF-EF, International Consultation on Incontinence Questionnaire-Short Form [ICIQ-SF]) were evaluated with analysis of variance and chi2 tests. RESULTS: At diagnosis, the prostate-specific antigen (PSA) level, clinical stage, Gleason sum distributions, body mass index, ICIQ-SF, and IPSS were not significantly different among the groups. IIEF-EF scores was higher in the HoLEP group (p=0.02). Mean operative time was longer in the OP group (p=0.02), but no difference was found in mean blood loss (p=0.5). Final pathology showed no substantial differences among the groups, although a lower positive surgical margin rate was found in the HoLEP group (p=0.04). Mean follow-up was 23.8+/-10.5 mo. The groups showed no statistical differences in urinary continence rate (p=0.6), IPSS (p=0.3), or IIEF-EF (p=0.4). CONCLUSIONS: NSRRP is feasible in prostate cancer patients who previously underwent HoLEP for BPE and provides satisfactory functional outcomes.     

Holmium laser enucleation of the prostate versus open prostatectomy for prostates greater than 100 grams: 5-year follow-up results of a randomised clinical trial

OBJECTIVES: To report 5-year follow-up results of a randomised clinical trial comparing holmium laser enucleation of the prostate (HoLEP) with open prostatectomy (OP). METHODS: One hundred twenty patients with prostates greater than 100g in weight according to transrectal ultrasound were randomised to either the HoLEP or the OP group (ie, 60 patients to each group). Preoperative and postoperative assessments included American Urological Association Symptom Score (AUA-SS), maximum urinary flow rates (Qmax), and postvoid residual urine (PVRU) volumes. Measurements were performed at 1, 3, 6, 12, 18, 24, 36, 48, and 60 mo. Postoperative outcome data were compared. All complications were recorded. RESULTS: Five years postoperatively, a total of 46 patients (38.3%) were lost to follow-up or had to be excluded from the study. All the remaining 74 patients (42 HoLEP vs. 32 OP patients, p=0.11) had undergone the 5-yr follow-up assessments. Mean AUA-SS was 3.0 in both groups (p=0.98), mean Qmax was 24.4 ml/s in both groups (p=0.97) and PVRU volume was 11 ml in the HoLEP and 5 ml in the OP group (p=0.25). Late complications consisted of urethral strictures and bladder-neck contractures; reoperation rates were 5% in the HoLEP and 6.7% in the OP group (p=1.0). No patient developed benign prostatic hyperplasia recurrence. CONCLUSIONS: Five years after the operation, the improvements in micturition obtained with HoLEP and OP were equally good, and reoperation rates similarly low. HoLEP seems to be a true endourological alternative to OP.     

Influence of prostate size on the outcome of holmium laser enucleation of the prostate

OBJECTIVE

To analyse the effect of prostate size on the outcome of holmium laser enucleation of prostate (HoLEP, an established procedure for treating symptomatic benign prostatic hypertrophy, BPH), in the initial 354 patients at 1 year of follow‐up.

PATIENTS AND METHODS

We retrospectively reviewed the records of 354 patients who had HoLEP at our institution from April 2003 to March 2007. In 235 patients the prostate weighed <60 g (group 1), in 77 it weighed 60–100 g (group 2) and in 42 >100 g (group 3). Demographic data and perioperative variables were recorded and compared among the three groups.

RESULTS

The mean prostate size was 38.1, 76.4 and 133.5 g for groups 1, 2 and 3, respectively (P < 0.001), and the respective mean weight of resected prostate was 18.47, 40.8 and 82.76 g, respectively (P < 0.001). The mean procedure efficiency increased from 0.36 g/min in group 1 to 0.49 g/min in group 2 and 0.58 g/min in group 3 (P < 0.001). The decrease in haemoglobin level after HoLEP was greater in group 3 than in the other groups. Overall, HoLEP resulted in a 75% reduction in American Urologic Association symptom score, a 225% increase in peak urinary flow rate and an 86% decrease in postvoid residual urine volume at 1 year of follow‐up. Perioperative complications were evenly distributed among the three groups, except for a higher incidence of superficial bladder mucosal injury and stenotic complications in group 3.

CONCLUSIONS

HoLEP is a safe and effective procedure for treating symptomatic BPH, independent of prostate size, and is associated with low morbidity. The efficiency of HoLEP increases with increasing prostate size.     

经尿道前列腺钬激光剜除术治疗良性前列腺增生的疗效研究

目的：观察经尿道前列腺钬激光剜除术（holmiumlaserenucleationoftheprostate,HoLEP）治疗良性前列腺增生的临床疗效及安全性。方法应用100W钬激光和组织粉碎器对480位良性前列腺增生症的患者行经尿道钬激光前列腺剜除术和组织粉碎术。分别记录患者术前、术中及术后随访的临床资料,分析及评估HoLEP的疗效及安全性。结果480例手术均成功,手术时间25～240min,平均（76．1±39．2）min,切除腺体15～320g,平均（45．8±15．4）g。术后留置导尿48～216h,平均（72．5±23．2）h,术后膀胱持续冲洗时间0～48h,平均（23．6士11．2）h,术后住院时间3～15d,平均（3．36±1．25）d,血红蛋白平均降低（1．1±0．5）g／dL。术后IPSS、QOL、Qmax、PVR较术前明显改善（P〈0．01）。术后并发症率低。结论经尿道前列腺钬激光剜除治疗良性前列腺增生疗效安全可靠,并发症少,剜除彻底,并且适应范围广,有可能挑战TURP成为治疗BPH的新的金标准。
