BPH Laser Therapy With Greenlight
Do I have to stay in the hospital after a GreenLight procedure?
GreenLight Laser Therapy is generally performed as a same-day surgical procedure. Typically, an overnight stay in the hospital is not required.10
How much does GreenLight cost?
GreenLight Laser Therapy is covered by Medicare and most private insurance. It&#;s still a good idea to discuss any deductibles or out-of-pocket costs with your doctor&#;s office upfront. There is no guarantee of insurance coverage for any procedure or product. It is the responsibility of the patient to contact their insurance provider for specific coverage information.
Does the GreenLight procedure affect sexual function?
In a recent study, 86% of patients reported improved or unchanged sexual satisfaction; 14% worsened. Similar outcomes were seen for erectile function.5
How long does it take until symptoms are relieved?
Most patients experience relief of symptoms and improvement in urine flow within 24 hours of the procedure. However, medical history, health conditions, and other factors can influence treatment and recovery.4
How long will symptom improvements last?
GreenLight Laser Therapy has proven durability out to 5 years.11,12
Will I continue to need prostate medication after the GreenLight procedure?
Most patients are able to discontinue taking their prostate medication within a few weeks after the GreenLight procedure.13 However, as with any medication, consult with your doctor before making any changes to your dosing.
How soon can I return to work?
Most patients can resume their normal activities within a couple of days. Strenuous activities can be resumed within a short time.4 Your doctor will discuss any restrictions and your specific condition with you during your visit following your procedure.
Greenlight laser (XPSTM) 180W prostatectomy for ...
ABSTRACT
Objectives
Safety of GreenLight&#; laser prostatectomy (GL-LP) in patients with ongoing blood thinners has been proven. Yet, the possibility of drug manipulation makes it a less challenging situation compared to treating patients with uncorrectable bleeding tendency. Herein, we aim at evaluating the outcomes of XPS&#;-180 W GL-LP for treatment of BPH in patients who had uncorrectable bleeding tendency due to hepatic dysfunction.
Methods
A prospectively maintained database for all patients who underwent GL-LP for symptomatic BPH was reviewed. Patients were divided into two groups based on the degree of hepatic dysfunction using Fib-4 index: Group 1 (indexed patients; low-risk Fib-4) and Group 2 (non-indexed patients; intermediate-high-risk Fib-4) included those who had chronic liver disease associated with either thrombocytopenia and/or hypoprothrombinemia. Primary outcome was the difference in perioperative bleeding complications between the two groups. Other outcome measures included all perioperative findings and complications as well-functional outcome measures.
Results
The study included 140 patients (93 indexed patients and 47 non-indexed). There were no significant differences between both groups in operative time, laser time and energy, auxiliary procedures, catheter time, hospital stay, and hemoglobin deficit. The need for blood transfusion was significantly more in group 2 (two patients (4.3%) versus no patients in group 1, P = 0.045). Perioperative and late postoperative complications were comparable for both groups (P = 0.634 and 0.858, respectively). There were no significant differences in the postoperative uroflow, symptoms score, and PSA reduction between the two groups (P = 0.57, 0.87, and 0.05, respectively).
Conclusions
XPS&#;-180 W GL-LP is a safe and effective technique for treatment of BPH in patients with uncorrectable bleeding tendency due to hepatic dysfunction.

Introduction
Surgical treatment of lower urinary tract symptoms (LUTS) caused by benign prostatic hyperplasia (BPH) of less than 80 gm has been changed from monopolar transurethral resection of the prostate (TURP) to transurethral resection in saline (TURIS) or vaporization techniques using Plasma kinetic or Laser energies [1]. GreenLight Photoselective vaporization prostatectomy (GL.PVP) was proved to be safe and effective treatment option [2]. As per Goliath trial, GreenLight laser PVP is non-inferior to TURP in an index case [3].
The high prevalence of chronic liver disease (CLD) in elderly Egyptians is attributed to past endemics of bilharziasis and hepatitis C virus infections leading to liver fibrosis and cirrhosis [4,5]. Patients with CLD represent a challenge to all surgical interventions because of the increased risk of intra and postoperative complications [6]. In surgical treatment of BPH, there is a concern about bleeding secondary to platelet deficiency, malfunction or both, and decreased prothrombin activity among these patients [7]. The advantages of GreenLight&#; laser prostatectomy (GL-LP) might be more obvious in non-index patients, especially those with increased risk of bleeding. GL-LP has the advantage of being safer for patients using antiplatelets or anticoagulants [8&#;13]. To the best of our knowledge, the safety of XPS/GL-LP in patients with bleeding tendency secondary to CLD was not previously reported.
This study was conducted to evaluate the outcomes of XPS-GreenLight&#;laser 180 W prostatectomy for the treatment of BPH in patients who had bleeding tendency due to hepatic dysfunction.
Patients and methods
Study design
A retrospective analysis of a prospectively maintained database of all consecutive patients who underwent GL-LP for symptomatic BPH between August and March was conducted. Patients with refractory LUTS secondary BPO or patients with urine retention secondary to BPO who failed medical therapy were eligible for inclusion in this study. They were enrolled in the study after obtaining written informed consent. Patients were not included if they had a neurological disorder, ongoing anticoagulants, or antiplatelet medications. Patients with a history of previous prostate surgery and patients diagnosed with prostate cancer were excluded. This study was performed in line with the principles of the Declaration of Helsinki.
The degree of hepatic fibrosis in patients with chronic liver disease was calculated using Fib-4 index (age [yr] × AST [U/L])/((PLT [109/L]) × (ALT [U/L])1/2) [14]. They were categorized into low-, intermediate-, and high-risk groups for advanced fibrosis based on the following suggested cut-offs: <1.30 (low risk), 1.30&#;2.67 (intermediate risk) and >2.67 (high risk) [15]. Patients were divided into two groups based on the degree of hepatic dysfunction using Fib-4 index: Group 1 (indexed patients; low-risk Fib-4) and Group 2 (non-indexed patients; intermediate-high-risk Fib-4).
Study workup
Preoperative workup included international prostate symptom score (IPSS), clinical examination, uroflowmetry, and post-voiding residual (PVR) estimation. Laboratory tests included complete blood count (CBC), hepatitis viral serology, prothrombin concentration, and prostate-specific antigen (PSA) estimation. Radiological investigations included trans-abdominal ultrasound and transrectal ultrasound (TRUS) ± prostate biopsy (as indicated by PSA and digital rectal exam). Baseline assessment includes IPSS, Qol score, Qmax, and PVR and follow-up was scheduled at 1, 3, 6, and 12 months and then annually.
Patients were divided into two groups according to bleeding tendency due to hepatic dysfunction. Group 1 (indexed patients) were those with normal coagulation profile. Group 2 (non-indexed patients) included those who had chronic liver disease (CLD) associated with either thrombocytopenia (platelet count <150,000/µl) [16], reduced prothrombin concentration (<70%), or both.
Intervention
Procedures were performed with patients under spinal anesthesia, and preoperative antibiotic prophylaxis was administered according to international guidelines. Urethrocystoscopy was performed for morphological assessment. XPS-180 W GreenLight&#; Laser machine (AMS, Minnetonka, MN, USA) with MoXy&#; fibers was used for all patients. All procedures were performed by two expert surgeons (AME and ML) who had passed the learning curve of GL-LP. According to prostate size and morphology as well as surgeon preference, the procedure was performed using technique of GL.PVP or GL.PVEP. In both techniques, the procedure started by creation of a working channel from the bladder neck till the verumontanum using 80 W power. In GL.PVP, prostatic lobes were vaporized as previously described till reaching the surgical capsule with gradually increasing the laser power to 180 W [17]. In GL.PVEP, vaporization of partially enucleated prostatic adenoma was performed as previously described [18,19].
Outcomes measures
Primary outcomes were differences in bleeding complications (intraoperative and postoperative), and hemoglobin and hematocrit deficit between the two groups. Secondary outcomes were time to catheter removal, length of hospital stay, and postoperative complications. All complications were classified based on a panel of GreenLaser users according to a modified Clavien classification [20]. The efficacy of the treatment was evaluated with IPSS, Qol score, Qmax, PVR, incidence of postoperative retention requiring catheterization, and the need for re-intervention. Postoperative PSA reduction was counted (preoperative PSA minus nadir postoperative PSA/preoperative PSA × 100) and compared.
Statistical analysis
Data were collected and analyzed using SPSS v21 statistical program. Continuous data were expressed as mean and standard deviation (SD) and compared between both groups using independent sample t-test or expressed as median and range and compared with Mann Whitney U-test as appropriate. Nominal data were expressed as numbers and percentages and compared using chi-square or Fisher&#;s exact test as appropriate. P value <0.05 was considered statistically significant.
Results
The study included 140 patients with a median prostate size of 65 (30&#;125 ml). Patients were 93 indexed patients, in group 1, and 47 were non-indexed, in group 2. summarizes preoperative patients and prostatic characteristics. summarizes operative and early postoperative outcomes. There were no significant differences between both groups in operative time, laser time, energy used and auxiliary procedures. Similarly, mean catheter time, hospital stay, and hemoglobin deficit were comparable between both groups.

After a median follow-up of 13.3 months (range 6.1&#;65.7), the mean Qmax was 21 ± 9 and 20 ± 9 ml/second in indexed and non-indexed patients, respectively (P = 0.572). The median IPSS, QoL, and PVR were 4, 1, and 15 ml for indexed patients and 5, 1, and 13.5 ml for non-indexed patients (P = 0.879, 0.880, and 0.830 respectively). The need for surgical reinterventions in the form of TURP for residual prostatic adenomas, incision for bladder neck contracture, urethrotomy for urethral stricture, and urethral sling were comparable for both groups (7.5% vs 8.5%). The mean percent reduction of PSA (SD) during follow-up was 66 (23)% in indexed patients vs 53 (25)% for non-indexed patients (P = 0.057).
Discussion
The present study has proven the safety and efficacy of XPS/GL-LP for surgical treatment of BPH in patients with bleeding tendency secondary to CLD. Intraoperative bleeding requiring coagulation using TURP loop was observed in 3.2% and 4.3% in indexed and non-indexed patients. While postoperative hematuria was encountered in 3.2% and 2.1%, respectively. These differences were not statistically significant. However, blood transfusion was needed in the two patients in non-indexed patients versus none of the indexed patients (P = 0.045). The reported hemorrhagic complications during XPS-GreenLight&#; 180 W Laser prostatectomy in patients with ongoing blood thinners were variably reported [9].
summarizes outcome of GL.XPS in patients with ongoing variable blood thinners [9,11,21&#;24]. On the contrary, Sachs et al. reported no hemorrhagic complications after PVP for 20 patients under novel anticoagulants using different GL.PVP generations in 3 centers [10].

The other primary endpoint in the present study was hemoglobin deficit. There was no significant difference between indexed and non-indexed patients (P = 0.772). The same was reported by Sohn et al. when they compared patients who stopped anticoagulant medications before GL.PVP with those who continued them [13] and spernatet al who evaluated GL.PVP in patients receiving clopidogrel [8]. The safety of GL.PVP in patients with bleeding tendency because of either CLD or continuing antiplatelets or anticoagulants is attributed to its absorption by oxyhemoglobin leading to an effective coagulated zone adjacent to the vaporization one [12].
Perioperative complications frequency in indexed and non-indexed patients in the present study were comparable (14% vs 17%, P = 0.634). Moreover, the severity of these complications was also comparable as grades 3 and 4 were observed in 4.3% and 6.4% for indexed and non-indexed patients, respectively (P = 0.594). Many studies reported comparable incidence of perioperative complications between patients receiving and not receiving anticoagulants [9,11] or antiplatelets [8].
The efficiency of successfully completing XPS-GreenLight&#; 180 W Laser prostatectomy in non-indexed patients was proved by lack of significant statistical differences between both groups in laser time, operative time, catheter time, and hospital stay ( ). Similarly, Knapp et al. had found comparable results for laser time and operative time, but significantly longer catheter period and hospital stay in anticoagulated patients when compared with controls [11]. The short-term success rates were comparable between both groups for the failed first trial of voiding, need for re-catheterization to manage AUR ( ).
The long-term outcomes as evaluated with IPSS, QoL score, Qmax, PVR, and percent reduction of PSA were also comparable in both groups. These results were in consistency with long-term functional outcomes reported by Ajib et al. for XPS-GreenLight&#; 180 W Laser prostatectomy [25]. The reintervention rates during follow-up for residual adenoma and bladder neck contracture were similar between both groups (4.3% and 2.1%, respectively), while reintervention for urethral stricture and urinary incontinence was needed in one patient of each group. The overall need for reintervention were 7.5% and 8.5% for indexed and non-indexed patients, respectively. A lower reoperation rate of 4.8% was reported by Calves et al. after a long-term follow-up for XPS-GreenLight&#; 180 W Laser prostatectomy [26]. However, calves et all relied on patients` reported outcomes (subjective) via a non-validated questionnaire.
Limitations of this study include the retrospective analysis that may have led to selection bias of doing non-indexed patients by more experienced surgeons. The strong points of this study are the prospective maintenance of the database, long-term follow-up, and classification of complications according to the system developed specifically for evaluating GreenLight Laser prostatectomy.
XPS-GreenLight&#; 180 W Laser prostatectomy is a safe and effective technique for treatment of patients with bleeding tendency due to hepatic dysfunction.
