Photoselective Vaporization of the Prostate with GreenLight 120-W Laser Compared with Monopolar Transurethral Resection of the Prostate: A Multicenter Randomized Controlled Trial

BACKGROUND Evidence supporting the widespread use of GreenLight High Performance System (HPS) 120-W photoselective vaporization of the prostate (PVP) is lacking. OBJECTIVE To assess the noninferiority of PVP compared with transurethral resection of the prostate (TURP) on urinary symptoms and the superiority of PVP over TURP on length of hospital stay. DESIGN, SETTING, AND PARTICIPANTS A multicenter randomized controlled trial was conducted. INTERVENTION Patients underwent monopolar TURP or PVP with the GreenLight HPS 120-W laser. MEASUREMENTS International Prostate Symptom Score (IPSS), Euro-QOL questionnaire, uroflowmetry, Danish Prostate Symptom Score Sexual Function Questionnaire, sexual satisfaction, and adverse events were collected at 1, 3, 6, and 12 mo. The two groups were compared using the 95% confidence interval (CI) of median difference for testing noninferiority of the IPSS at 12 mo and the student t test for testing the difference in length of hospital stay. RESULTS AND LIMITATIONS A total of 139 patients (70 vs 69 men in each group) were randomized. Median IPSS scores at 12-mo follow-up were 5 (interquartile range [IQR]: 3-8) for TURP versus 6 (IQR: 3-9) for PVP, and the 95% CI of the difference of the median was equal to -2 to 3. Because the upper limit of the 95% CI was >2 (the noninferiority margin), the hypothesis of noninferiority could not be considered demonstrated. Median length of stay was significantly shorter in the PVP group than in the TURP group, with a median of 1 (IQR: 1-2) versus 2.5 (IQR: 2-3.5), respectively (p<0.0001). Uroflowmetry parameters and complications were comparable in both groups. Sexual outcomes were slightly better in the PVP group without reaching statistical significance. CONCLUSIONS The present study failed to demonstrate the noninferiority of 120-W GreenLight PVP versus TURP on prostate symptoms at 1 yr but showed that PVP was associated with a shorter length of stay in the hospital. TRIAL REGISTRATION NCT01043588.

Intestinal Perforation as a Complication of Tension–Free Vaginal Tape Procedure for Urinary Incontinence

Objectives: To report and prevent a serious complication of tension–free vaginal tape (TVT) procedure. Case Report: One day after a TVT procedure, an emergency CT scan showed adhesion of intestinal loops with a pneumoperitoneum. The patient had previously had intra– and retroperitoneal surgery with a sacral cervicopexy and a Burch colposuspension. Conclusion: In such a case of previous surgery, a CT scan may be useful before a TVT procedure.

Ureteral and Multifocal Tumours Have Worse Prognosis than Renal Pelvic Tumours in Urothelial Carcinoma of the Upper Urinary Tract Treated by Nephroureterectomy

BACKGROUND It is not known whether the primary tumour location of upper urinary tract urothelial carcinoma (UUT-UC) is associated with prognosis. OBJECTIVE To evaluate the impact of initial primary tumour location on survival in patients who had undergone radical nephroureterectomy (RNU). DESIGN, SETTING, AND PARTICIPANTS Using a multi-institutional, retrospective database, we identified 609 patients with UUT-UC who had undergone RNU between 1995 and 2010. Tumour location was categorised as renal pelvis, ureter, or multifocal. INTERVENTION All patients had undergone RNU. MEASUREMENTS Tumour location was tested as a prognostic factor for survival through univariate and multivariable Cox regression analysis. RESULTS AND LIMITATIONS Tumour location was renal pelvis in 317 cases (52%), ureter in 185 cases (30%), and multifocal in 107 cases (18%). Compared to renal pelvic and ureteral tumours, multifocal tumours were more likely to be associated with advanced stages (pT3/pT4; 39%, 30%, and 54%, respectively; p<0.001) and high-grade disease (53%, 56%, and 76%, respectively; p<0.001). On multivariable analysis, tumour location was an independent prognostic factor for cancer-specific death, disease recurrence, and metastasis (p<0.05). The 5-yr cancer-specific death-free survival probability was 86.8% for renal pelvic tumours, 68.9% for ureteral tumours, and 56.8% for multifocal tumours (p<0.001). The retrospective design of this study was its main limitation. CONCLUSIONS Ureteral and multifocal tumours had a worse prognosis than renal pelvic tumours. These findings are not in line with recently published data and should be investigated in a prospective assessment to obtain a definitive statement regarding this matter.

180-W XPS GreenLight Laser Vaporisation Versus Transurethral Resection of the Prostate for the Treatment of Benign Prostatic Obstruction: 6-Month Safety and Efficacy Results of a European Multicentre Randomised Trial—The GOLIATH Study

BACKGROUND The comparative outcome with GreenLight (GL) photoselective vaporisation of the prostate and transurethral resection of the prostate (TURP) in men with lower urinary tract symptoms due to benign prostatic obstruction (BPO) has been questioned. OBJECTIVE The primary objective of the GOLIATH study was to evaluate the noninferiority of 180-W GL XPS (XPS) to TURP for International Prostate Symptom Score (IPSS) and maximum flow rate (Qmax) at 6 mo and the proportion of patients who were complication free. DESIGN, SETTING, AND PARTICIPANTS Prospective randomised controlled trial at 29 centres in 9 European countries involving 281 patients with BPO. INTERVENTION 180-W GL XPS system or TURP. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Measurements used were IPSS, Qmax, prostate volume (PV), postvoid residual (PVR) and complications, perioperative parameters, and reintervention rates. Noninferiority was evaluated using one-sided tests at the 2.5% level of significance. The statistical significance of other comparisons was assessed at the (two-sided) 5% level. RESULTS AND LIMITATIONS The study demonstrated the noninferiority of XPS to TURP for IPSS, Qmax, and complication-free proportion. PV and PVR were comparable between groups. Time until stable health status, length of catheterisation, and length of hospital stay were superior with XPS (p<0.001). Early reintervention rate within 30 d was three times higher after TURP (p=0.025); however, the overall postoperative reintervention rates were not significantly different between treatment arms. A limitation was the short follow-up. CONCLUSIONS XPS was shown to be noninferior (comparable) to TURP in terms of IPSS, Qmax, and proportion of patients free of complications. XPS results in a lower rate of early reinterventions but has a similar rate after 6 mo. TRIAL REGISTRATION ClinicalTrials.gov, identifier NCT01218672.

Influence of Photoselective Vaporization of the Prostate on Sexual Function: Results of a Prospective Analysis of 149 Patients with Long-Term Follow-Up

BACKGROUND Even though transurethral resection of the prostate remains the gold standard treatment for lower urinary tract symptoms (LUTS) refractory to medical therapy, photoselective vaporization of the prostate (PVP) has become a popular alternative. Early PVP studies seem encouraging, but few data exist regarding the effect of PVP on sexual function at long-term follow-up. OBJECTIVE Our aim was to evaluate the impact of PVP on erectile function (EF) at long-term follow-up in men with LUTS due to benign prostatic hyperplasia (BPH). DESIGN, SETTING, AND PARTICIPANTS One hundred forty-nine consecutive patients who underwent a prostate vaporization with the GreenLight laser performed by a single surgeon (FB) were prospectively enrolled in this study. INTERVENTION All patients underwent PVP with the GreenLight laser performed by one experienced surgeon. MEASUREMENTS All patients were evaluated by International Index of Erectile Function (IIEF-5) preoperatively and at 1, 3, 6, and 12 mo and then once a year. At each visit, the questionnaires were collected, and each patients maximum flow rate and postvoid residual volume were measured with ultrasound. Biologic data were also collected at each visit, including prostate-specific antigen, creatinine, and bacterial urine culture. RESULTS AND LIMITATIONS One hundred forty-nine patients were enrolled in the study. Median patient age was 74 yr. Urinary function was significantly improved over baseline in both men with normal or abnormal preoperative erectile function. Energy used was 255+/-129kJ. Hospitalization stay was 2.2+/-3.1 d. Other than a temporary difference at 1 yr, IIEF-5 scores were comparable preoperatively and postoperatively if we consider all the population. However, considering patients with preoperative IIEF-5 >19, the postoperative IIEF-5 scores were significantly decreased at 6, 12, and 24 mo. CONCLUSIONS Sexual function appears to be maintained after PVP; however, in patients with normal preoperative EF, we showed a significant decrease in EF after PVP.

A European Multicenter Randomized Noninferiority Trial Comparing 180 W GreenLight XPS Laser Vaporization and Transurethral Resection of the Prostate for the Treatment of Benign Prostatic Obstruction: 12-Month Results of the GOLIATH Study

PURPOSE We present the 1-year results of the GOLIATH prospective randomized controlled trial comparing transurethral resection of the prostate to GreenLight XPS for the treatment of men with nonneurogenic lower urinary tract symptoms due to prostate enlargement. The updated results at 1 year show that transurethral resection of the prostate and GreenLight XPS remain equivalent, and confirm the therapeutic durability of both procedures. We also report 1-year followup data from several functional questionnaires (OABq-SF, ICIQ-SF and IIEF-5) and objective assessments. MATERIALS AND METHODS A total of 291 patients were enrolled at 29 sites in 9 European countries. Patients were randomized 1:1 to undergo GreenLight XPS or transurethral resection of the prostate. The trial was designed to evaluate the hypothesis that GreenLight XPS is noninferior to transurethral resection of the prostate on the International Prostate Symptom Score at 6 months. Several objective parameters were assessed, including maximum urinary flow rate, post-void residual urine volume, prostate volume and prostate specific antigen, in addition to functional questionnaires and adverse events at each followup. RESULTS Of the 291 enrolled patients 281 were randomized and 269 received treatment. Noninferiority of GreenLight XPS was maintained at 12 months. Maximum urinary flow rate, post-void residual urine volume, prostate volume and prostate specific antigen were not statistically different between the treatment arms at 12 months. The complication-free rate at 1 year was 84.6% after GreenLight XPS vs 80.5% after transurethral resection of the prostate. At 12 months 4 patients treated with GreenLight XPS and 4 who underwent transurethral resection of the prostate had unresolved urinary incontinence. CONCLUSIONS Followup at 1 year demonstrated that photoselective vaporization of the prostate produced efficacy outcomes similar to those of transurethral resection of the prostate. The complication-free rates and overall reintervention rates were comparable between the treatment groups.

A Multicenter Randomized Noninferiority Trial Comparing GreenLight-XPS Laser Vaporization of the Prostate and Transurethral Resection of the Prostate for the Treatment of Benign Prostatic Obstruction: Two-yr Outcomes of the GOLIATH Study

BACKGROUND The GOLIATH study is a 2-yr trial comparing transurethral resection of prostate (TURP) to photoselective vaporization with the GreenLight XPS Laser System (GL-XPS) for the treatment of benign prostatic obstruction (BPO). Noninferiority of GL-XPS to TURP was demonstrated based on a 6-mo follow-up from the study. OBJECTIVE To determine whether treatment effects observed at 6 mo between GL-XPS and TURP was maintained at the 2-yr follow-up. DESIGN, SETTING, AND PARTICIPANTS Prospective randomized controlled trial at 29 centers in nine European countries involving 281 patients with BPO. INTERVENTION Photoselective vaporization using the 180-W GreenLight GL-XPS or conventional (monopolar or bipolar) TURP. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary outcome was the International Prostate Symptom Score for which a margin of three was used to evaluate the noninferiority of GL-XPS. Secondary outcomes included Qmax, prostate volume, prostate specific antigen, Overactive Bladder Questionnaire Short Form, International Consultation on Incontinence Questionnaire Short Form, occurrence of surgical retreatment, and freedom from complications. RESULTS AND LIMITATIONS One hundred and thirty-six patients were treated using GL-XPS and 133 using TURP. Noninferiority of GL-XPS on International Prostate Symptom Score, Qmax, and freedom from complications was demonstrated at 6-mo and was sustained at 2-yr. The proportion of patients complication-free through 24-mo was 83.6% GL-XPS versus 78.9% TURP. Reductions in prostate volume and prostate specific antigen were similar in both arms and sustained over the course of the trial. Compared with the 1(st) yr of the study, very few adverse events or retreatments were reported in either arm. Treatment differences in the Overactive Bladder Questionnaire Short Form observed at 12-mo were not statistically significant at 24-mo. A limitation was that patients and treating physicians were not blinded to the therapy. CONCLUSIONS Twenty-four-mo follow-up data demonstrated that GL-XPS provides a durable surgical option for the treatment of BPO that exhibits efficacy and safety outcomes similar to TURP. PATIENT SUMMARY The long-term effectiveness and safety of GLP-XLS was similar to conventional TURP for the treatment of prostate enlargement.

Renal Cell Carcinoma (RCC) in Patients With End-Stage Renal Disease Exhibits Many Favourable Clinical, Pathologic, and Outcome Features Compared With RCC in the General Population

BACKGROUND Patients with end-stage renal disease (ESRD) are at risk of developing renal tumours. OBJECTIVE Compare clinical, pathologic, and outcome features of renal cell carcinomas (RCCs) in ESRD patients and in patients from the general population. DESIGN, SETTING, AND PARTICIPANTS Twenty-four French university departments of urology participated in this retrospective study. INTERVENTION All patients were treated according to current European Association of Urology guidelines. MEASUREMENTS Age, sex, symptoms, tumour staging and grading, histologic subtype, and outcome were recorded in a unique database. Categoric and continuous variables were compared by using chi-square and student statistical analyses. Cancer-specific survival (CSS) was assessed by Kaplan-Meier and Cox methods. RESULTS AND LIMITATIONS The study included 1250 RCC patients: 303 with ESRD and 947 from the general population. In the ESRD patients, age at diagnosis was younger (55 ± 12 yr vs 62 ± 12 yr); mean tumour size was smaller (3.7 ± 2.6 cm vs 7.3 ± 3.8 cm); asymptomatic (87% vs 44%), low-grade (68% vs 42%), and papillary tumours were more frequent (37% vs 7%); and poor performance status (PS; 24% vs 37%) and advanced T categories (≥ 3) were more rare (10% vs 42%). Consistently, nodal invasion (3% vs 12%) and distant metastases (2% vs 15%) occurred less frequently in ESRD patients. After a median follow-up of 33 mo (range: 1-299 mo), 13 ESRD patients (4.3%), and 261 general population patients (27.6%) had died from cancer. In univariate analysis, histologic subtype, symptoms at diagnosis, poor PS, advanced TNM stage, high Fuhrman grade, large tumour size, and non-ESRD diagnosis context were adverse predictors for survival. However, only PS, TNM stage, and Fuhrman grade remained independent CSS predictors in multivariate analysis. The limitation of this study is related to the retrospective design. CONCLUSIONS RCC arising in native kidneys of ESRD patients seems to exhibit many favourable clinical, pathologic, and outcome features compared with those diagnosed in patients from the general population.
