Objectives: This prospective, randomized, medium-term trial aimed to assess the efficiency, safety and postoperative results of bipolar plasma vaporization (BPV) in comparison with monopolar transurethral resection (TUR) in cases of secondary bladder neck sclerosis (BNS).
Methods: A total of 70 patients with BNS secondary to transurethral resection of the prostate (TURP; 46 cases), open prostatectomy for benign prostatic hypertrophy (BPH; 18 cases) and radical prostatectomy for prostate cancer (6 cases) were enrolled in the trial. The inclusion criteria consisted of maximum flow rate (Q max) <10 ml/s and International Prostate Symptom Score (IPSS) >19. All patients were evaluated preoperatively and at 1, 3, 6, 12 and 18 months after surgery by IPSS, quality of life score (QoL), Q max and postvoiding residual urinary volume (PVR).
Results: The mean operation time (10.3 versus 14.9 minutes), catheterization period (0.75 versus 2.1 days) and hospital stay (1.1 versus 3.2 days) were significantly reduced in the BPV series. During the immediate postoperative follow up, recatheterization for acute urinary retention only occurred in the TUR series (5.7%). The medium-term retreatment requirements due to BNS recurrence were lower in the BPV study arm (2.8% versus 8.5%). At the 1, 3, 6, 12 and 18 months assessments, statistically similar parameters were found concerning the IPSS and QoL symptom scores, Q max and PVR values specific for the two therapeutic alternatives.
Conclusions: BPV constitutes a valuable endoscopic treatment approach for secondary BNS. The method emphasized superior efficacy, a satisfactory safety profile and similar medium-term follow-up features when compared with standard TUR.

Development and external validation of a model to predict recurrence in patients with non-muscle invasive bladder cancer.

Background: Most patients initially diagnosed with non-muscle invasive bladder cancer (NMIBC) still have frequent recurrence after urethral bladder tumor electrodesiccation supplemented with intravesical instillation therapy, and their risk of recurrence is difficult to predict. Risk prediction models used to predict postoperative recurrence in patients with NMIBC have limitations, such as a limited number of included cases and a lack of validation. Therefore, there is an urgent need to develop new models to compensate for the shortcomings and potentially provide evidence for predicting postoperative recurrence in NMIBC patients.

Background: We compared the safety and efficacy of holmium laser enucleation of the prostate (HoLEP) and transurethral resection of the prostate (TURP) in elderly men (aged ≥75 years) with benign prostatic hyperplasia (BPH).
Methods: A retrospective analysis of 151 patients (HoLEP: 72; TURP: 79) was conducted. Preoperative and postoperative parameters, including prostate size, International Prostate Symptom Score (IPSS), catheterization duration, hospital stay, and perioperative complications (incontinence and dysuria), were analyzed.

Bladder cancer ranks as the 9th most common type of cancer worldwide. Approximately 70 % of bladder cancers are diagnosed as non-muscle invasive, and they are treated with transurethral resection followed by intravesical therapy. Doxorubicin is one of the effective cytotoxic drugs used in intravesical and systemic therapy, but its cardiotoxicity and nephrotoxicity limit therapeutic dosages.
