Narrow-band imaging cystoscopy in non-muscle-invasive bladder cancer: a prospective comparison to the standard approach.

Objectives: A single-centre, prospective trial was performed aiming to assess the impact of narrow-band imaging (NBI) cystoscopy in cases of non-muscle-invasive bladder cancer (NMIBC) in comparison to standard white light cystoscopy (WLC).

Materials And Methods: A total of 95 NMIBC-suspected consecutive cases were enrolled. The inclusion criteria were hematuria, positive urinary cytology or ultrasound suspicion of bladder tumors.

Narrow band imaging cystoscopy and bipolar plasma vaporization for large nonmuscle-invasive bladder tumors--results of a prospective, randomized comparison to the standard approach.

Objective: To evaluate the efficacy of narrow band imaging (NBI) cystoscopy associated with bipolar plasma vaporization (BPV) in cases of large nonmuscle-invasive bladder tumors (NMIBTs) compared with white light cystoscopy (WLC) and monopolar transurethral resection of bladder tumors (TURBTs).

Methods: A total of 220 cases with ≥ 1 bladder tumor >3 cm determined by abdominal ultrasonography, computed tomography, and flexible WLC were included in the present trial. The patients in the first arm underwent WLC and NBI cystoscopy followed by BPV, and the patients in the second arm underwent only WLC and TURBT.

Bipolar plasma vaporization vs monopolar and bipolar TURP-A prospective, randomized, long-term comparison.

Objective: To perform a prospective, randomized, long-term comparison between bipolar plasma vaporization of the prostate (BPVP), bipolar transurethral resection in saline (TURis), and monopolar transurethral resection of the prostate (TURP) concerning the perioperative and follow-up parameters.

Methods: A total of 510 patients with benign prostatic hyperplasia (BPH), Q(max) <10 mL/s, International Prostate Symptom Score (IPSS) >19, and prostate volume between 30 and 80 mL were enrolled in the trial. All cases were evaluated preoperatively and at 1, 3, 6, 12, and 18 months after surgery by IPSS, quality of life, Q(max), and ultrasonography.

Treatment changes and long-term recurrence rates after hexaminolevulinate (HAL) fluorescence cystoscopy: does it really make a difference in patients with non-muscle-invasive bladder cancer (NMIBC)?

Objectives: •  To evaluate in a prospective, randomized study the impact of hexaminolevulinate blue-light cystoscopy (HAL-BLC) on the diagnostic accuracy and treatment changes in cases of non-muscle invasive bladder cancer (NMIBC) compared with standard white-light cystoscopy (WLC). •  To compare the long-term recurrence rates in the two study arms.

Patients And Methods: •  In all, 362 patients suspected of NMIBC were included in the trial based on positive urinary cytology and/or ultrasonographic suspicion of bladder tumours and underwent transurethral resection of bladder tumours.

Innovative technique in nonmuscle invasive bladder cancer-bipolar plasma vaporization.

Objectives: To evaluate the efficacy and safety of a newly introduced endoscopic technique in the treatment of nonmuscle-invasive bladder tumors (NMIBT), the bipolar plasma vaporization of bladder tumors (BPV-BT), and to compare it with monopolar transurethral resection of bladder tumors (TURBT).

Methods: A total of 120 patients with at least one bladder tumor larger than 3 cm were enrolled in the study and randomized for BPV-BT and TURBT. Resection biopsy followed by tumor plasma vaporization and biopsies of the tumoral bed were performed in the 60 cases of the BPV-BT arm.

HAL blue-light cystoscopy in high-risk nonmuscle-invasive bladder cancer--re-TURBT recurrence rates in a prospective, randomized study.

Objectives: To evaluate the impact of hexaminolevulinate blue-light cystoscopy and transurethral resection of bladder tumors (TURBT) upon the short-term recurrence rate in high-risk nonmuscle-invasive bladder cancer (NMIBC) compared with conventional cystoscopy and resection.

Methods: Between December 2007 and November 2009, 446 patients were randomized for blue-light cystoscopy/resection and for standard cystoscopy/resection, respectively. The inclusion criteria consisted of positive urinary cytology and ultrasonographic suspicion of bladder tumors.

Transurethral resection (TUR) in saline plasma vaporization of the prostate vs standard TUR of the prostate: 'the better choice' in benign prostatic hyperplasia?

Objective: To evaluate the efficiency, safety and short-term outcome of transurethral resection in saline plasma vaporization of the prostate (TURis-PVP), and to compare it to the standard TUR of the prostate (TURP).

Patients And Methods: In all, 155 patients with benign prostatic enlargement (BPE) secondary to benign prostatic hyperplasia (BPH), with a maximum urinary flow rate (Q(max) ) of <10 mL/s, an International Prostate Symptom Score (IPSS) of >19 and prostate volume of 30-80 mL were enrolled in this prospective, randomized trial. All patients were evaluated preoperatively and at 1, 3 and 6 months after surgery by IPSS, health-related quality of life (HRQL) score, Q(max) and postvoid residual urine volume (PVR).

Bipolar resection of the bladder and prostate--initial experience with a newly developed regular sized loop resectoscope.

Objective: Bipolar transurethral resection (TUR) has been introduced in the clinical practice nowadays. Benefits from bipolar TUR are represented by the use of saline irrigation, which avoids hypoosmotic hyperhydration (TUR-Syndrome), as well as by the reduced risk of obturator nerve stimulation. However, the previously introduced smaller bipolar resection loop caused prolonged operating-time.
