RESUMO
Objective: To evaluate transperineal laser ablation (TPLA) with Echolaser® (Echolaser® TPLA, Elesta S.p.A., Calenzano, Italy) as a treatment for benign prostatic hyperplasia (BPH) and prostate cancer (PCa) using the Delphi consensus method. Methods: Italian and international experts on BPH and PCa participated in a collaborative consensus project. During two rounds, they expressed their opinions on Echolaser® TPLA for the treatment of BPH and PCa answering online questionnaires on indications, methodology, and potential complications of this technology. Level of agreement or disagreement to reach consensus was set at 75%. If the consensus was not achieved, questions were modified after each round. A final round was performed during an online meeting, in which results were discussed and finalized. Results: Thirty-two out of forty invited experts participated and consensus was reached on all topics. Agreement was achieved on recommending Echolaser® TPLA as a treatment of BPH in patients with ample range of prostate volume, from <40 mL (80%) to >80 mL (80%), comorbidities (100%), antiplatelet or anticoagulant treatment (96%), indwelling catheter (77%), and strong will of preserving ejaculatory function (100%). Majority of respondents agreed that Echolaser® TPLA is a potential option for the treatment of localized PCa (78%) and recommended it for low-risk PCa (90%). During the final round, experts concluded that it can be used for intermediate-risk PCa and it should be proposed as an effective alternative to radical prostatectomy for patients with strong will of avoiding urinary incontinence and sexual dysfunction. Almost all participants agreed that the transperineal approach of this organ-sparing technique is safer than transrectal and transurethral approaches typical of other techniques (97% of agreement among experts). Pre-procedural assessment, technical aspects, post-procedural catheterization, pharmacological therapy, and expected outcomes were discussed, leading to statements and recommendations. Conclusion: Echolaser® TPLA is a safe and effective procedure that treats BPH and localized PCa with satisfactory functional and sexual outcomes.
RESUMO
BACKGROUND: In our study, we aimed to test the efficacy and safety of Trans-Perineal Laser Ablation of the prostate (TPLA®) in the surgical treatment of high-risk Benign Prostatic Obstruction (BPO) patients. METHODS: We defined a high-risk BPO patient as an elderly man affected by severe comorbidities, among which coagulation issues due to pre-existent medications or diseases. From October 2020 to June 2022, we prospectively enrolled high-risk patients affected by a moderate to severe and/or complicated BPO condition. The analysis of the efficacy of the Trans-Perineal Laser Ablation was defined as the primary endpoint of the study. Secondary endpoints were post-operative surgical complications and patient-reported quality of life. RESULTS: Globally, 40 consecutive patients were enrolled. Median (IQR) age was 80 (72.5-84) years. Median Charlson Comorbidity Index was 6 (5-7). Median prostate volume was 38 (30.5-73) cc. In all cases, a TPLA® procedure was performed under local anesthesia, and patients being discharged within the same day of the procedure. A progressive reduction of median prostate volumes was reported at 3 and 6 months post-operatively, compared to baseline [38 (30.5-73) vs 35 (26-49) vs 34 (28-49) cc, p < 0.001]. Median International Prostate Symptom Score (IPSS) improved accordingly [25 (19-30) vs 10.5 (7.5-13) vs 8 (6-11.5), p < 0.001]. A permanent bladder catheter was successfully removed in 13 out of 23 (56.5%) cases. Within 90 days from surgery, 19 (47.5%) patients experienced at least one surgical complication. According to the Clavien-Dindo classification, complications were classified as grade I in 16 (40%) cases, grade II in 9 (22.5%), and grade III in 1 (2.5%). We did not observe any grade IV or V complications. CONCLUSIONS: The Trans-Perineal Laser Ablation of the Prostate is a feasible, safe, and effective Minimally Invasive Surgical Technique, when offered to elderly, high-risk patients affected by severe Benign Prostatic Obstruction.
RESUMO
BACKGROUND: Human ejaculation can be defined as a complex and still largely unknown function. Since decades, Benign Prostatic Hyperplasia (BPH) surgery-associated loss of antegrade ejaculation has been reported as a bother by many patients. New technologies and modified surgical techniques were developed, to reduce the impact of ejaculatory dysfunction on patients' perceived quality of life. Recently, the emerging of the new Minimally Invasive Surgical Techniques (MISTs) empowered the urological surgeons with the technological means to introduce the ejaculation-sparing principles into everyday clinical practice. METHODS: Our paper was conceived as a state-of-the-art analysis about the anatomical and physiological premises of the human ejaculation and their clinical application in the field of ejaculation-sparing surgery for the treatment of Lower Urinary Tract Symptoms (LUTS). Moreover, we proposed an innovative physiological model for antegrade ejaculation. RESULTS: We analysed the elements of the "ejaculatory apparatus" from an anatomical point of view. We investigated the physio-pathological models of the human ejaculation, from the classical "combustion chamber" paradigm to the new evidences by which it could be overcome. Finally, we provided a synthetic literature review about the ejaculation-sparing techniques for BPH surgery. Particularly, we distinguished them between classical techniques, modified for ejaculation-preserving purposes, and the new MISTs, characterized by the introduction of new technologies and different treatment modalities. CONCLUSIONS: Modified surgical techniques and new technologies opened new perspectives about human ejaculation. Previously established functional paradigms were questioned and overcome by recent clinical evidence. The new MISTs gained a prominent role in the process, opening a whole new era for BPH surgery.

BACKGROUND: Benign Prostatic Obstruction (BPO) is the most common non-malignant urological condition among men and its incidence rise with age. Among prostate treatments, GreenLight laser seems to reduce bleeding and would be safer in the aging population. AIMS: We aimed to compare the functional outcomes and safety profile of < 75 years old (Group A) and ≥ 75 years old (Group B) patients. METHODS: In a multicenter setting, we retrospectively analyzed all the patients treated with GreenLight Laser vaporization of the prostate (PVP). RESULTS: 1077 patients were eligible for this study. 757 belonged to Group A (median age 66 years) and 320 to Group B (median age 78 years). No differences were present between the two groups in terms of prostate volume, operative time, hospital stay, PSA decrease over time after surgery, complications and re-intervention rate with a median follow-up period of 18 months (IQR 12-26). Nevertheless, focusing on complications, GreenLight laser PVP demonstrated an excellent safety profile in terms of hospital stay, re-intervention and complications, with an overall 29.6% complication rate in older patients and only two cases of Clavien III. Functional outcomes were similar at 12 month and became in favor of Group A over time. These data are satisfactory with a Qmax improvement of 111.7% and an IPSS reduction of 69.5% in older patients. DISCUSSION AND CONCLUSIONS: GreenLight laser photoselective vaporization of the prostate is a safe and efficient procedure for all patients, despite their age, with comparable outcomes and an equal safety profile.

PURPOSE: Greenlight laser is a mini-invasive technique used to treat Benign Prostatic Obstruction (BPO). Some of the advantages of GreenLight photoselective vaporization (PVP) are shorter catheterization time and hospital stay compared to TURP. Post-operative acute urinary retention (pAUR) leads to patients' discomfort, prolonged hospital stay and increased health care costs. We analyzed risk factors for urinary retention after GreenLight laser PVP. MATERIALS AND METHODS: In a multicenter experience, we retrospectively analyzed the onset of early and late post-operative acute urinary retention in patients undergoing standard or anatomical PVP. The pre-, intra- and post-operative characteristics were compared betweene patients who started to void and the patients who developed post-operative urinary retention. RESULTS: The study included 434 patients suitable for the study. Post-operative acute urinary retention occurred in 39 (9%). Patients with a lower prostate volume (P < .001), an adenoma volume lower than 40 mL (P < .001), and lower lasing time (P = .013) had a higher probability to develop pAUR at the univariate analysis. The multivariate logistic regression confirmed that lower lasing time (95% CI: 0.86-0.99, OR = 0.93, P = .046) and adenoma volume (95% CI: 0.89-0.98, OR = 0.94, P = .006) are correlated to pAUR. Furthermore IPSS ≥ 19 (95% CI: 1.19- 10.75, OR = 2.27, P = .023) and treatment with 5-ARI (95% CI: 1.05-15.03, OR = 3.98, P = .042) are risk factors for pAUR. CONCLUSION: In our series, post-operative acute urinary retention was related to low adenoma volume and lasing time, pre-operative IPSS ≥ 19 and 5-ARI intake. These data should be considered in deciding the best timing for urethral catheters removal.

PURPOSE: To present the step-by-step description of an ejaculation-sparing anatomic photo-selective vaporization of the prostate (PVP) technique. To report the results of a series of ejaculation-sparing versus non-ejaculation-sparing anatomic PVPs. METHODS: Sexually active, benign prostatic hyperplasia (BPH) patients undergoing an anatomic PVP between 11/2018 and 2/2020 were included. Patients were divided into group A (ejaculation-sparing surgery) and group B (control group). Baseline, peri-operative and 6-months follow-up data were evaluated. Lower urinary tract symptoms (LUTS) and sexual function were assessed through internationally validated questionnaires. Groups were matched by an inverse probability of treatment weighting (IPTW) analysis. Logistic univariable regression analysis was performed to detect predictors of antegrade ejaculation preservation. RESULTS: Overall, 76 patients were included, among which 15 in group A and 61 in group B. Median (inter-quartile range, IQR) age was 72 (66.5-77) years, median (IQR) prostate volume 63.5 (54.5-98.5) cc. No differences about peri-operative outcomes were detected, included high-grade complications. At 6-months follow-up, no differences in urinary or erectile function were detected between groups, while ejaculation-sparing patients showed better Male Sexual Health Questionnaire (MSHQ) scores [7 (1-13) vs. 1 (1-1), p < 0.001] and higher rates of antegrade ejaculation (60% vs. 13.1%, p < 0.001). The ejaculation-sparing technique was identified as a predictor of post-operative antegrade ejaculation (OR 19.3, CI 95% 7.2-51.2, p < 0.001). CONCLUSION: The ejaculation-sparing anatomic PVP showed superiority over the control group in post-operative ejaculatory function scores and antegrade ejaculation rates. Besides, preliminary results suggested similar effectiveness in LUTS relief at a short-term follow-up.

BACKGROUND: Over the two past decades, GreenLight laser therapy has been considered a valid alternative for the treatment of lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia/benign prostatic obstruction (BPH/BPO). However, the debate on the effectiveness of laser therapy compared to conventional techniques is still open. The aim of our study is to analyze and describe the use of GreenLight laser prostate surgery in Italy, with regard to the surgical techniques performed and the surgical and functional outcomes at mid-term follow-up. METHODS: From March 2012 to July 2018, patients who underwent GreenLight laser prostate surgery for LUTS due to BPH/BPO from 19 Italian centers were included. The following parameters were evaluated in the population: age, prostate volume, prostate adenoma volume, PSA tot, Q

OBJECTIVES: Chronic prostatitis syndrome is a bothering and poorly understood condition. Many patients report genitourinary pain and Lower Urinary Tract Symptoms as a main complaint. Many different pharmacological or behavioural therapies are prescribed in daily clinical practice, but efficacy data are still lacking. The aim of our study was to test the efficacy and safety of a transrectal delivered association of Boswellia resin extract and propolis derived polyphenols for the relief of prostatitis - like symptoms. MATERIALS AND METHODS: Patients affected by chronic/recurrent prostatitis - like symptoms were prospectively enrolled in our study from December, 2016 to December, 2018. Patients were screened at baseline through clinical examination and validated questionnaires administration: Chronic Prostatitis Symptom Index (CPSI), International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF). Inclusion criteria were: age ≥ 18; prostatitis symptoms persisting for at least 3 of the last 6 months; CPSI pain domain score ≥ 5; previous negative Meares-Stamey test. Treatment consisted on the administration of 1 suppository containing Boswellia resin extract and propolis derived polyphenols, once a day for 20 days. The primary endpoint of the study was the improvement of quality of life after treatment, defined by a reduction of ≥ 2 points, or ≥ 25%, of mean CPSI pain domain score, compared to baseline. Secondary endpoints were the improvement of post-treatment CPSI total score and the analysis of treatment - related adverse events. All patients were re-evaluated 1 month after treatment. RESULTS: 40 patients were enrolled in our study. Median age (Inter - Quartile Range IQR) was 51.5 (41.5-63.2) years. Mean baseline CPSI scores were: 22.15 (total score), 9.67 (pain domain), 5.15 (micturition domain) and 7.35 (quality of life domain), respectively. No significant adverse events were reported. At 1 month follow-up, CPSI scores appeared modified as follows: 16.40 (total score, p = 0.001); 6.92 (pain domain; p = 0.001; 4.02 (micturition domain, p = 0.09); 5.45 (quality of life domain, p = 0.002). Mean CPSI pain domain score reduction was -2.75 points (-28.5%). Mean CPSI total score reduction was -5.75 points (-26%). CONCLUSIONS: The association of Boswellia resin extract and propolis derived polyphenols can reduce genitourinary pain and then improve quality of life of men affected by bothersome prostatitis - like symptoms.

Introduction: GreenLight laser vaporization of the prostate (photoselective vaporization of the prostate [PVP]) is a safe and effective procedure for Benign Prostatic Hyperplasia. Long-term results and advantages of PVP in patients with large and symptomatic prostate are still under evaluation. Materials and Methods: In a multicenter experience, patients who underwent standard or anatomical PVP were retrospectively reviewed. Patients with follow-up >12 months were divided into two groups based on prostate volume (<100 cc vs ≥100 cc). Pre- and perioperative data, as well as postoperative results and complications, were recorded after 3, 6, and 12 months and then annually. Results: One thousand and thirty-one patients were eligible, 916 of these had a prostate volume of <100 cc and 115 ≥ 100 cc. Median follow-up period was 25.0 months (interquartile range [IQR] 16.5-35.0) and 16.0 months (IQR 12.0-24.0) in ≥100 and <100 groups, respectively. No difference was found in terms of catheterization time, postoperative stay, and postoperative acute urine retention. Patients with prostate ≥100 required longer operative time (75 vs 55 minutes), lasing time (41.7 vs 24.9 minutes), and higher energy used but lower energy density. Patients with prostate ≥100 had a higher incidence of early (50.4% vs 35.7%) and late complications (21.7% vs 12.8%) and early urge/incontinence symptoms (40.9% vs 29.3%). No statistically significant differences were found for the maximum urinary flow (Qmax) and International Prostate Symptom Score (IPSS) results between the two groups. The reintervention rate in ≥100 group was 3.5% vs 2.3% in <100. Conclusions: In the midterm follow-up, GreenLight PVP guarantees the same results in different prostate volume groups. Early and late complications are more frequent in large prostates.

PURPOSE: To evaluate in details the actual extent of double-J stent-related symptoms after semirigid (URS) and flexible (RIRS) ureteroscopy using a validated questionnaire. METHODS: We asked to complete the Ureteric Stent Symptoms Questionnaire (USSQ) to all stone patients undergoing URS or RIRS with stent placement from 2010 to 2015. Stent-related symptoms' prevalence, severity, and impact on daily life were analyzed using descriptive statistics and five-order Likert scales. Subgroups analyses were performed. RESULTS: 232 patients completed the USSQ. Stents had a deep impact on urinary symptoms (daily frequency ≥ 1 per hour 59.1%, ≥ 1 nocturnal micturition 90.1%, urgency 86.6%, burning 82.3%) that represented a problem for 88.4% of patients. 83.2% complained of pain, mostly in the kidney (67.9%) or in the bladder area (31.3%), particularly during physical activity (72.9%) and micturition (77.0%). Pain interfered with everyday life in 92.2%. General health, working, and sexual activity were also affected. 62.0% of patients would be dissatisfied (51.6% unhappy or terrible) if further ureteral stenting was proposed in future. Younger patients and females were more affected. Limitations include observational design and lack of baseline evaluation. CONCLUSIONS: Ureteral stents are responsible for significant urinary symptoms and pain after semirigid and flexible ureteroscopy. They also considerably affect general health, working and sexual activity. Urologists should consider it carefully before stenting, inform patients about stent-related symptoms, and minimize stent indwelling time.

PURPOSE: The main risk factor for bladder cancer (BC) is cigarette smoking, but also occupational exposure to carcinogens is relevant, causing about 4-10% of BC. We aimed at investigating the association between BC risk, occupations held in the past and exposure to occupational carcinogens, also assessing whether these associations were influenced by tumour grade. METHODS: We pooled data from two Italian case-control studies on male BC, analyzing 893 cases and 978 controls. Occupations were classified using the International Standard Classification of Occupations and exposure to carcinogens was assigned using a validated Job Exposure Matrix. Logistic regression approach was used as well as a semi-Bayesian model, based on a priori information on exposure. RESULTS: A significantly increased BC risk was found for chemical engineering technicians, postmen, and lathe operators, but only, for the latter, the association remained significant after Bayesian control for type I error. Among carcinogens, cadmium and trichloroethylene were associated with BC. When analyzing data by grade, exposure to these carcinogens was associated with low-grade BC only. CONCLUSIONS: Our results suggest that monitoring workplaces to prevent exposure to carcinogenic agents is still an important task, which should be still given adequate importance in public health.

BACKGROUND: Major acute cardiovascular events (MACE) prevalence after 180-W GreenLight (180-W GL) laser photoselective vaporization (PVP) have never been explored. Aim of our study is to evaluate perioperative MACE that occurred concomitantly with 180-W GL PVP. MATERIALS AND METHODS: We relied on a multi-institutional database that included 14 centers. Data from 923 patients who underwent 180-W GL PVP were reviewed. We abstracted pre- and perioperative data of patients who experienced perioperative MACE, such as angina pectoris, acute myocardial infarction, other chronic ischemic heart disease, transient ischemic attack, or cerebrovascular accident as well as deep venous thrombosis with or without pulmonary embolism. We relied on a case-series format to report the main findings of our analyses. RESULTS: 18 (1.9%) patients reported MACE in 7 centers. Median age was 69.5 (IQR 66.0-79.2) years. Of all, 7 patients underwent standard PVP and 11 anatomical PVP. Eleven patients (61.1%) were not under anticoagulant/antiplatelet treatment, 6 (33.3%) were under low dose aspirin, and 1 (5.6%) was under clopidogrel. Four patients (22.2%) had an instrumental and laboratory diagnosis of myocardial infarction, 7 (38.9%) had an episode of angina pectoris with or without rhythm alteration, 3 (16.7%) reported symptomatic deep venous thrombosis, and 4 (22.2%) had other MACE-like events. CONCLUSIONS: Physician should take in consideration the possibility of MACE or MACE-like events. The real MACE rate may be different as only half of included centers reported MACE. Since the main target of laser surgery are high-risk bleeding patients, prospective observational trials focused on detection of these possible complications are warranted.

BACKGROUND: Retrograde intra-renal surgery (RIRS) has become increasingly common and is mainly performed under general anesthesia (GA). There are no specific papers about RIRS performed under spinal anesthesia (SA). Our objective was to evaluate feasibility and results of RIRS performed under SA. METHODS: We analyzed all consecutive RIRS performed for stones in day surgery from March 2008 to September 2012. Single procedures outcomes of RIRS performed under SA were evaluated with US and KUB X-ray at 2 weeks. Further treatments, operative time and complications were also evaluated. Outcomes of RIRS performed under SA and GA were compared. Difference between groups was statistically analyzed. Significance level was set at P<0.05. RESULTS: One hundred thirty-nine RIRS under SA and 47 under GA were considered. Mean stone burden was 14±6 mm. No case of conversion from SA to GA occurred. Stone-free rate (SFR) level 4U of RIRS under SA and under GA were respectively 63.6% and 48.6%, SFR level 0U 24.5% and 25.7%, CIRF 39.1% and 22.9%. Further treatments were performed respectively in 20.8% and in 23.4%. No anesthesia-related and Clavien-Dindo grade ≥3 complications occurred. No statistically significant difference was found in stone-free rates, CIRF and significant residual fragments rates, need for further procedures, operative time and complications between the two groups. CONCLUSIONS: RIRS under SA seems feasible and effective for renal stones in day surgery. Results seem equivalent to RIRS under GA. SA can be considered for RIRS as an alternative to GA.

BACKGROUND AND OBJECTIVES: Renal transplant recipients (RTRs) have a 2- to 7-fold risk of developing a neoplasm compared to general population. Bladder urothelial neoplasms in this cohort has an incidence of 0.4-2%. Many reports describe a more aggressive behavior. The objective of this study is to describe oncologic characteristics of bladder urothelial neoplasms in RTRs and to evaluate its recurrence, progression, and survival rates. METHODS: A retrospective multicentered study was performed evaluating all de novo bladder urothelial neoplasms cases in RTRs from 1988 to 2014. Descriptive statistical analysis and evaluation of recurrence, progression, and survival rates were performed. RESULTS: A total of 28 de novo bladder transitional cell carcinomas (TCCs) were identified (incidence rate 0.64%). Cancer-specific survival rates were 100, 75, and 70% after 1, 5, and 10 years, respectively. Age at diagnosis superior to 60 years was found to be a statistically significant variable for recurrence risk. Progression rate was 14%. Presence of CIS was significantly associated with progression. All cancer-specific deaths were in the high-risk group and all were progressions from non-muscle invasive to muscle invasive bladder cancer. CONCLUSIONS: Bladder urothelial neoplasms following renal transplant is associated with a trend toward worst prognosis. Early aggressive treatments, such as early radical cystectomy, might be advisable to reduce cancer-specific deaths.

CONTEXT: Von Hippel-Lindau disease (VHLD) is a rare inherited neoplastic syndrome. Among all the VHLD-associated tumors, clear cell renal cell carcinoma (ccRCC) is the major cause of death. OBJECTIVE: The aim of this paper is the discovery of new non-invasive biomarker for the monitoring of VHLD patients. MATERIALS AND METHODS: We compared the urinary proteome of VHLD patients, ccRCC patients and healthy volunteers. RESULTS: Among all differentially expressed proteins, alpha-1-antitrypsin (A1AT) and APOH (beta-2-glycoprotein-1) are strongly over-abundant only in the urine of VHLD patients with a history of ccRCC. DISCUSSION AND CONCLUSION: A1AT and APOH could be promising non-invasive biomarkers.

PURPOSE: To compare the efficacy, safety, Patient Global Impression of Improvement (PGI-I), and complications rates after 180-W GreenLight laser (180-W GL laser) standard and anatomical photoselective vaporization (sPVP and aPVP). METHODS: Within a multi-institutional database, we identified patients who underwent sPVP or aPVP to relief BPH symptoms. IPSS, Q max, and prostate-specific antigen (PSA) were measured at baseline and during the follow-up. PGI-I score as well as early and late complications were recorded at follow-up visits. Log-binomial and multivariable proportional odds regression models were fitted to estimate the effect of aPVP vs. sPVP on PGI-I as well as on early and late complication rates, before and after adjustment for propensity score. RESULTS: 813 patients were included. Of those, the 50.4% underwent aPVP. Patients who underwent aPVP had larger prostate (64 vs. 55 mL, p < 0.001) and higher baseline PSA levels (3.1 vs. 2.5 ng/mL, p < 0.001). PGI-I score was signaled as very improved, improved, slightly improved, unchanged, or worsened in 55.5, 32.8, 8.3, 2.3, and 1.2% of the cases, respectively, with no differences according the technique used (p = 0.420). Acute urinary retention occurred in 9.2 vs. 8.9% of patients after aPVP vs. sPVP (p = 0.872). All models failed to find differences in: patients' satisfaction (OR 1.19, p = 0.256), early complications (RR 0.93, p = 0.387), early urge/incontinence symptoms (RR 0.97, p = 0.814), and late complications rates (RR 0.70, p = 0.053), after aPVP vs. sPVP. CONCLUSION: Our results showed similar functional results and complication rates after aPVP and sPVP. However, aPVP was used in larger prostates. Both techniques guarantee high patient's satisfaction.

INTRODUCTION: Management of renal-cell carcinoma (RCC) in patients with Von Hippel-Lindau syndrome (VHL) represents a clinical dilemma: the oncologic outcomes must be weighed against preservation of renal function. Radiofrequency ablation (RFA) is currently used in selected cases for treatment of small-size RCC. The aim of this study was to evaluate the safety, complications, and functional and oncologic outcomes of RFA in the treatment of RCC in VHL patients. PATIENTS AND METHODS: RCCs were treated with ultrasound-guided RFA or with laparoscopic RFA. Clinical and radiologic response, disease recurrence, and survival outcomes were evaluated during follow-up. Early and late complications were recorded and graded. RESULTS: Nine RCC patients underwent RFA. The median number of RCCs per patient was 3 (interquartile range, 2-4). Among these 9 patients, a total of 20 RCCs were treated by RFA (19 ultrasound-guided RFA and 1 laparoscopic procedure). Median RCC size was 2.5 cm (interquartile range, 2.0-3.0). RFA did not impair renal function (P = .35). In 2 cases disease persisted, and in 1 case disease recurred after 18 months. These patients were retreated with ultrasound-guided RFA with complete response and no renal function impairment. RFA treatment was overall well tolerated and safe. No complications were recorded. Postoperative stay was no longer than 1 day. CONCLUSION: RCC occurred in about two-thirds of VHL patients, who had young age at presentation; it was frequently multifocal and recurrent. The use of RFA, with extended indications, could represent a tailored treatment for VHL patients, reducing the risk of renal failure and resulting in satisfying oncologic results.
RESUMO
INTRODUCTION: Von Hippel-Lindau (VHL) disease is an autosomal dominant inherited syndrome occurring in one out of 36,000 live births. Diagnosis could be a challenge in patients with no familial VHL history. Renal cancer (RCC) represents one of the most important manifestations. RCC is usually recurrent and multifocal. Actually treating RCC in VHL patients represent a clinical dilemma: the oncological outcomes must be balanced against renal function preservation. CASE PRESENTATION: A young man with a negative familial history was referred to our department with seven misdiagnosed renal masses. VHL disease was determined through genetic test. The multiple RCCs were treated by surgery and percutaneous thermal ablation by radiofrequency ablation (RFA) with complete control of RCC and no impairment of renal function. CONCLUSIONS: This case history confirms that VHL disease has to be suspected in young patients with evidence of synchronous multiple renal masses and in presence of specific clinical criteria.RFA appears to be safe in terms of oncological radicalism and in renal function preservation.In hereditary RCC, we should purpose, whenever it is possible, minimally invasive treatment in terms of low hospital stay and a minimal loss of renal tissue.
RESUMO
PURPOSES: GreenLight laser has gained increasing acceptance as a less invasive treatment for lower urinary tract symptoms due to benign prostatic hyperplasia (BPH/LUTS). Three surgical options were developed: standard photovaporization (PVP), anatomical PVP and GreenLight enucleation of prostate (GreenLEP); however, literature lacks a direct comparison among the procedures. Aim of the present study is to compare the three techniques in a multicentre series of patients. METHODS: Data were collected from consecutive patients with indication to surgical management of BPH/LUTS in five institutions. Patients underwent standard PVP, anatomical PVP or GreenLEP according to surgeon preferences. Standard parameters associated with transurethral prostate surgery were documented prior surgery and during the follow-up. Patients' perception of improvement was measured using a single-item scale. Early (within first 30 post-operative days) and delayed post-operative complications were recorded. Descriptive statistics, univariate and multivariate analysis were used. RESULTS: We evaluate 367 consecutive patients (mean age 69.1 years). Median prostate size and PSA were 68 ml (IQR 50-90) and 2.8 ng/ml (IQR 1.7-4.3), respectively. The median operative time and applied energy were 60 min (IQR 45-75) and 250 kJ (IQR 160-364). Catheterization time and median post-operative stay were 1 and 2 days. No patient was transfused. The overall median Q max values increased for 8-19 ml/s (p < 0.05), median International Prostate Symptoms Score decreased from 24 to 7 (p < 0.05). A total of 7.4% urinary retention, 33.4% bothersome storage symptoms, 2.5% short-term stress incontinence were recorded. Three heart attacks, one pulmonary embolism and one death occurred. Prostate volume was a predictive factor for post-operative storage symptoms (p = 0.049). Nine percentage of patients experienced long-term complications (4, 0.9 and 0.9% of urethral stricture, bladder neck contracture and prostatic fossa sclerosis, respectively) with 2.5% of long-term stress urinary incontinence (conservatively managed). The reintervention rate was 6%. Late complications were associated at univariate analysis with pharmacological therapy (combination therapy vs. alpha blockers alone vs. none: p value = 0.042) and with the surgical approach (standard PVP vs. anatomical PVP vs. GreenLEP p value = 0.011). The patients' perception of satisfaction was 68% "greatly improved", 27% "improved", 4% "not changed" and 1% "worsened" with no differences between techniques. CONCLUSION: The availability of three different GreenLight laser techniques allows surgeons with different skills to safety use this technology that remains effective with high patient satisfaction. Anatomical vaporization seems to guarantee the best balance between functional outcomes, surgical procedures and complications.

Bladder cancer (BC) has a typical aetiology characterized by a multistep carcinogenesis due to environmental exposures, genetic susceptibility, and their interaction. Several lines of evidence suggest that DNA repair plays a role in the development and progression of BC. In particular, the study of individual susceptibility to DNA double strand breaks (DSBs) may provide valuable information on BC risk, and help to identify those patients at high-risk of either recurrence or progression of the disease, possibly personalizing both surveillance and treatment. Among the different DSB markers, the most well characterized is phosphorylation of the histone H2AX (γ-H2AX). We assessed any potential role of γ-H2AX as a molecular biomarker in a case-control study (146 cases and 146 controls) to identify individuals with increased BC risk and at high-risk of disease recurrence or progression. We investigated γ-H2AX levels in peripheral blood mononuclear cells before and after their exposure to ionizing radiation (IR). We did not find any significant difference among cases and controls. However, we observed a significant association between γ-H2AX basal levels and risk of disease recurrence or progression. In particular, both BC patients as a whole and the subgroup of non-muscle invasive BC (NMIBC) with high basal H2AX phosphorylation levels had a decreased risk of recurrence or progression (for all BC HR 0.70, 95%CI 0.52-0.94, P = 0.02; for NMIBC HR 0.68, 95%CI 0.50-0.92, P = 0.01), suggesting a protective effect of basal DSB signaling. Our data suggest that γ-H2AX can be considered as a potential molecular biomarker to identify patients with a higher risk of BC recurrence. © 2015 Wiley Periodicals, Inc.
