Our study was intended to verify the efficacy and the side effects of intraluminal dilatation of the distal urinary tract with vascular balloon catheter in a group of patients with urethral stenosis. In 6 out of 10 patients, there was a significant increase in urethral diameter (by 70% to 150%). In 4 patients, the stenosis was only slightly improved (increase in urethral diameter by 10% to 20%). Only 5 patients, all belonging to the group in which dilatation was anatomically effective, have been having normal micturition and have been asymptomatic. According to data in our possession, transurethral dilatation does not seem to be very effective, since it restores adequate micturition in only 50% of cases. In view of the absence of severe side effects, however, this technique may be indicated in patients with medical problems that preclude surgery.

No Right Way: Removal of a Pencil Foreign Body From a Male Urethra.
Cureus
November 2024
Urology, Sunderland Royal Hospital, Sunderland, GBR.
Foreign body insertion into the urethra is uncommonly encountered in urology practice. Such insertion can result in a myriad of problems including bleeding, infectious sequelae, urinary retention, urethral injury or rupture, and resultant urethral stricture formation. This article describes a case in which an elderly male inserted a pencil into his urethra, which subsequently became lodged and required removal under regional anesthesia in the operating theater.

Medicine and Surgery, University Hospitals Coventry and Warwickshire, Coventry, GBR.
The Optilume drug-coated balloon (DCB) (North Plymouth, USA) is a novel treatment option for urethral stricture disease that combines mechanical dilation with localized delivery of paclitaxel, an antiproliferative drug aimed at reducing recurrence rates by inhibiting scar tissue formation. This systematic review and meta-analysis, conducted using studies published in the last 10 years up to November 2024, assessed the efficacy and safety of Optilume DCB across seven studies involving 457 patients. Key outcomes included significant reductions in symptom scores, as measured by the International Prostate Symptom Score (IPSS), and improvements in urinary flow rates (QMax).

Introduction: Although failures are undesirable, they offer valuable learning opportunities that drive progress through necessary changes. This concept holds particularly true in the history of urethral reconstruction.
Methods: A comprehensive literature review was conducted using PubMed, focusing on the history of the urethral stricture and current trends based on national and international guidelines for urethral stricture management.

Objective: The current management for complex urethral strictures commonly uses open reconstruction with buccal mucosa urethroplasty. However, there are multiple situations whereby buccal mucosa is inadequate (pan-urethral stricture or prior buccal harvest) or inappropriate for utilization (heavy tobacco use or oral radiation). Multiple options exist for use as alternatives or adjuncts to buccal mucosa in complex urethral strictures (injectable antifibrotic agents, augmentation urethroplasty with skin flaps, lingual mucosa, bladder mucosa, colonic mucosa, and new developments in tissue engineering for urethral graft material) (1, 2).

Background: Urocystolithiasis is a common problem in dogs; many canine uroliths are resistant to medical dissolution. Novel management options would expand, and in some cases improve, current urolith retrieval strategies.
Hypothesis/objectives: To describe a previously unreported technique by the Ellik bladder evacuator (EE) to assist in minimally invasive, cystoscopic retrieval of canine cystoliths.
