Introduction: Benign prostatic hyperplasia (BPH) is a prevalent condition in ageing men, often resulting in significant lower urinary tract symptoms (LUTS) that impact quality of life. For patients with huge prostate volumes (>150 mL), surgical management presents challenges. Traditionally, open simple prostatectomy (OSP) was the gold standard; however, minimally invasive approaches such as robotic-assisted simple prostatectomy (RASP) and endoscopic enucleation of the prostate (EEP), especially holmium laser enucleation of the prostate (HoLEP), offer similar or superior outcomes with reduced morbidity.

Background: Holmium enucleation of the prostate is currently the treatment of choice for the management of complicated or drug-unresponsive lower urinary tract symptoms due to benign prostate hyperplasia (BPH). Thulium Fiber Laser (TFL) is an alternative to holmium laser and seems to be safe and effective. We aimed to report our initial experience with TFL.

Article Synopsis
  • - The study compared the effectiveness of robot-assisted radical cystectomy with intracorporeal urinary diversion (RARC + ICUD) to open radical cystectomy (ORC) for treating bladder cancer, analyzing data from 316 patients between 2014 and 2023.
  • - Findings showed that RARC + ICUD led to significantly lower risks of complications, blood loss, and hospital stays, and resulted in higher lymph node counts compared to ORC, implying better immediate surgical outcomes.
  • - Despite better perioperative results for RARC + ICUD, the long-term cancer-related outcomes, including survival and recurrence rates, were similar between both surgical approaches.

Identification of clinically positive pelvic lymph node metastases (cN+) in patients with muscle-invasive bladder cancer is currently challenging, as the diagnostic accuracy of available imaging modalities is limited. Conventional CT is still considered the gold-standard approach to diagnose lymph node metastases in these patients. The development of innovative diagnostic methods including radiomics, artificial intelligence-based models and molecular biomarkers might offer new perspectives for the diagnosis of cN+ disease.
