Efficacy and safety profile of GreenLight laser photoselective vaporization of the prostate in ≥ 75 years old patients: results from the Italian GreenLight Laser Study Group.

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.

Stone free rate and clinical complications in patients submitted to retrograde intrarenal surgery (RIRS): Our experience in 571 consecutive cases.

Introduction: The purpose of this study is to report the stone free rate (SFR) and clinical complications in patients submitted to retrograde intrarenal surgery (RIRS).

Materials And Methods: A total of 571 procedures of upper urinary stones treated using flexible ureteroscopy and holmium laser lithotripsy from January 2014 to February 2020 have been analyzed. Overall SFR was evaluated after 3 months following the procedure by means of a non-contrast computed tomography.

Post-Operative Acute Urinary Retention After Greenlight Laser. Analysis of Risk Factors from A Multicentric Database.

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.

UVENTA urethral stents: Are we taking a step forward? The first clinical series.

Objectives: To describe first clinical results in term of safety, complications and short term efficacy of temporary placement of UVENTA urethral stent in the treatment of urethral and bladder neck strictures.

Methods: UVENTA urethral stent (Taewoong Medical) is a temporary self expandable covered metallic stent. Anti-migration system and different radial force distribution are the two main innovations.

Operative profile, safety and functional outcomes after GreenLight laser prostate surgery: results from a 12 months follow-up multicenter Italian cohort analyses.

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.

GreenLight Photoselective Vaporization of the Prostate: One Laser for Different Prostate Sizes.

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. In a multicenter experience, patients who underwent standard or anatomical PVP were retrospectively reviewed.

Standard vs. anatomical 180-W GreenLight laser photoselective vaporization of the prostate: a propensity score analysis.

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 , and prostate-specific antigen (PSA) were measured at baseline and during the follow-up.

Vaporize, anatomically vaporize or enucleate the prostate? The flexible use of the GreenLight laser.

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.

Prevalence of hypertension in patients on peritoneal dialysis: results of an Italian multicentre study.

Background: The tenet that peritoneal dialysis is capable of either normalizing or improving blood pressure control in uraemic patients is based on outdated or monocentric experiences. Therefore, we assessed the prevalence of hypertension and the efficacy of antihypertensive therapy in a large, multicentric cohort of patients on peritoneal dialysis.

Methods: Twenty seven out of the 50 centres belonging to the Italian Co-operative Peritoneal Dialysis Study Group took part in the study.

Myths and reality concerning hypertension in peritoneal dialysis patients: results of a multicenter study.

OBJECTIVES: To evaluate the prevalence of hypertension, the average blood pressure level, the 24 h blood pressure profile, and the efficacy of antihypertensive therapy for a large population of peritoneal dialysis patients.DESIGN: A cross-sectional, observational multicenter study. METHODS: From 504 peritoneal dialysis patients (18% of the Italian peritoneal dialysis population) involved in a multicenter observational study, we selected 414 who had undergone successful ambulatory blood pressure monitoring (i.

Dialysis-related amyloidosis in a large CAPD population.

We studied 212 patients from 13 Italian dialysis centers to evaluate the clinical aspects of dialysis-related amyloidosis in continuous ambulatory peritoneal dialysis (CAPD). The mean age was 64.2 +/- 12.

Forecasting correct sodium balance in hemodiafiltration procedures involving infusions.

Four patients, stable on acetate hemodialysis (AHD), were switched to acetate-free biofiltration (AFB) which differs from AHD and bicarbonate hemodialysis (BHD) in that the dialysate contains no buffer, which is given intravenously as a hypertonic (1/6 M) Na bicarbonate solution. Within the 1st month the patients developed thirst and hypertension attributed to a positive Na balance. The aim of this investigation was to check this (1) by a study based on the predictable changes induced in the body compartments of 13 patients by the infusion and ultrafiltration (UF) of a hypertonic solution and (2) by direct determination and calculation of 28 Na mass balances in BHD and AFB.

[Flow cytometry in micturitional urine: its clinical application in cases of bladder cancer].

The paper discusses a particular use of flow cytometric analysis, namely the quantitative study of DNA in the cellular sediment obtained from micturitional urine in patients with vesical tumours. Forty cases of carcinoma of varying degrees and stages were studied and, despite the small number of cases, interesting results have emerged regarding the close correlation between the test and the different clinical, cytological and histopathological aspects of the disease, and relating to the relative simplicity of the method used.

Transport of water and solutes in uremic patients with chronic hepatic disease in CAPD.

Ten patients with chronic hepatic disease (CHD) were compared with 34 non-CHD (N) pts. All patients underwent a peritoneal equilibration test; the asymptotic curves for small solutes transport were transformed into straight lines; protein transport was also expressed as a straight line; the slopes of these linear functions were used as index of solute transfer. CHD patients showed increased UF and transport of all solutes.

[Potassium removal: a factor limiting the correction of acidosis during dialysis].

The diffusional fluxes of urea, potassium and bicarbonate across the dialytic membrane (external balance), and across the cellular membrane (internal balance), were determined in 7 patients in haemodialysis using potassium free dialysate and dialysate containing 2.0 mEq/1 of potassium. The results obtained show an inverse correlation between extraction of potassium and intake of bicarbonate in both external and internal balance.

Potassium removal as a factor limiting the correction of acidosis during dialysis.

The diffusional fluxes of urea, potassium and bicarbonate across the dialysis membrane (external balance) were determined in seven patients during haemodialysis using potassium free dialysate and dialysate containing 2.0mEq/L of potassium. The results show an inverse correlation between extraction of potassium and intake of bicarbonate in both external and internal balances.

Hemodialysis with "adequate" sodium concentration in dialysate.

This investigation was undertaken to define the "adequate" sodium concentration in the dialytic fluid allowing to maintain a stable plasma effective osmolality during dialysis. Isonatric dialysate is shown to miss this aim by inducing a predictable postdialytic hypernatremia. To avoid this effect a new approach was made.
