Urachal adenocarcinoma represents the third most common histological type of non-urotelial bladder cancer. A very low incidence of this disease and the lack of prospective studies have led to a rich and heterogeneous treatment history. Currently, the standard of care for these patients is represented by partial cystectomy en bloc with resection of the urachal ligament and total omphalectomy.

Pathophysiological mechanisms in detrusor underactivity: Novel experimental findings.

Low Urin Tract Symptoms

May 2019

Faculty of Medicine, University of Porto, Department of Urology, Hospital São João, Porto, Portugal.

Underactive bladder (UAB) is a multifactorial symptom complex often related to detrusor underactivity (DU). Although recognized as a common cause of lower urinary tract symptoms and with significant effects on quality of life, UAB/DU is largely underresearched. Herein, we review up-to-date knowledge on the pathophysiological mechanisms of UAB/DU, with an emphasis on the relationship between UAB and bladder outlet obstruction (BOO).

Unlabelled: Transurethral resection of the prostate as well as laser prostatectomy (by either holmium laser enucleation of the prostate or Greenlight laser vaporization) is associated with risks of sexual dysfunction such as antegrade ejaculation and occasionally erectile dysfunction. While ejaculation-sparing variations of these techniques show promising results, larger multicenter studies are needed to confirm promising data. Prostatic urethral lift maintains erectile and ejaculatory function at 5-yr follow-up.

Objectives: The study compared the transurethral resection in saline (TURis), transurethral vaporization in saline (TUVis), bipolar plasma enucleation of the prostate (BPEP), and open prostatectomy (OP) in a single-center, prospective, randomized controlled clinical setting exclusively involving large prostate patients.

Patients And Methods: During a 4½ year enrollment period, 320 cases of prostate volume over 80 mL, maximum flow rate (Qmax) below 10 mL/second, International Prostate Symptom Score (IPSS) over 19, or urinary retention were included in the trial and equally randomized in the four study arms. Patients were assessed preoperatively as well as at the 1-, 3-, 6-, and 12-month follow-up checkups using the IPSS, quality of life (QoL) score, Qmax, postvoiding residual urinary volume (PVR), and prostate-specific antigen (PSA).

Flexible uretero-renoscopy witnessed dramatic technological improvements, ultimately translating in more diverse indications, better instrument durability, procedural efficacy and safety. Diagnostic exploration of the upper urinary tract, treatment of selected cases of ureteral and especially pyelocaliceal stones, caliceal diverticulum and infundibular stenosis, treatment, and follow-up of upper urinary tract tumors are the main indications for this approach. We review the technique, results and complications of retrograde flexible ureteroscopy, with an emphasis on the latest developments of the method.

Substantial advances in ureteroscopy have resulted in the incorporation of this procedure into routine urological practice in many centres worldwide. Subsequently, an abundance of clinical data and technological progression have enabled the development of novel solutions that have increased the efficacy of ureteroscopy, and reduced associated morbidity and costs. In addition the indications for this retrograde approach have been expanded, and pyelocalyceal diverticulum, infundibular stenosis, urolithiasis in pregnant women or in patients with urinary diversions, as well as upper urinary tract tumours can now be managed using this methodology.

Introduction: A long term, retrospective study was performed aiming to outline a critical comparison concerning the efficacy, safety and durability of the bipolar plasma vaporization (BPV), standard monopolar transurethral resection (TUR) and "cold-knife" "star" transurethral incision (TUI) in secondary bladder neck sclerosis (BNS) cases.

Materials & Methods: Of the 126 patients included in the trial based on maximum flow rate (Qmax) below 10 mL/s and International Prostate Symptom Score (IPSS) over 19, classical resection was performed in 46 cases, "cold-knife" TUI in 37 cases and bipolar vaporization in 43 patients. The evaluation protocol comprised IPSS, QoL (quality of life) score, Qmax and PVR (post-voiding residual urinary volume) assessment performed at 1, 3, 6, 12, 18 and 24 months after the initial intervention.

Introduction: Secondary bladder neck sclerosis (BNS) represents a common late complication of prostate surgery, however so far insufficiently assessed in the available literature. More over, the previously attempted and analyzed therapeutic modalities failed to achieve acknowledgement as standard treatment for this particular pathology.

Methods: The bipolar plasma vaporization (BPV) was introduced as a viable mean of removing the obstructing scar formation in a gradual fashion.

Unlabelled: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: According to the EAU Guidelines 2012, large size benign prostatic hyperplasia (BPH) cases (>80 mL) continue to have open prostatectomy as the first line treatment alternative, despite the substantial peri-operative morbidity and extended catheterization and convalescence periods related to this undoubtedly invasive approach. During the past two decades, holmium laser enucleation of the prostate was constantly described as a successful choice for this category of patients. According to rather numerous studies, the technique displayed superior results in terms of surgical safety and postoperative recovery compared with the open procedure.

There is still an ongoing debate regarding the optimal endourological treatment of upper urinary tract lithiasis, a significant parameter being the stone free rate. However, despite the apparent simplicity of notions such as stone free or success rate, when analyzing the available literature one may discover the complex, intricate and debatable issues behind them. The main problems reside in the heterogeneous way of defining intervention success, the timing at which a patient is considered stone-free and also in the lack of standard postoperative evaluation of patients with urolithiasis.
