“…In addition, another common cause is improper indwelling catheter. 11 When the catheter is too thick and hard, or indwelling for too long, it is easy to induce tissue inflammation, and the urethral mucous membrane will be compressed resulting in ischemic necrosis.…”

In this study, a reproducible urethral injury animal model was developed and the role of the biodegradable drug-eluting urethral stent in limiting urethral stricture formation after urethral injury was evaluated. A total of 22 rabbits were used, and 20 rabbits were randomly chosen to develop urethral injury animal model. Bulbar urethral injury was made by a self-designed explosion device in the 20 rabbits. The urethral injury animal model was then randomly assigned to 2 groups of 10 each, which received a treatment of biodegradable paclitaxel-eluting urethral stent or only end-to-end anastomosis. Other two rabbits served as normal control group. Stents were surgically implanted into the injured urethras of rabbits under direct vision. Reparative effects, including stent degradation, were evaluated by urethroscopy, retrograde urethrography, and histology at different intervals at weeks 4, 8, and 12. In stent-free group, 8 of 10 rabbits developed obvious urethral stricture which was demonstrated by urethroscopy and retrograde urethrography, while in biodegradable paclitaxel-eluting stent group, urethral stricture was absent in all animals (p < 0.05). Histological follow-up indicated that the drug-eluting stents can also minimize the inflammatory reactions and fibrosis formation compared with the stent-free groups. Scanning electron microscope demonstrated that the biodegradable drug-eluting stent can gradually degrade in 12 weeks. The biodegradable paclitaxel-eluting urethral stent is effective in limiting urethral stricture formation after urethral injury.

“…Catheter-related injuries are also associated with significant long-term complications, such as urethral stricture, required urethral dilation or urethrotomy, long-term indwelling suprapubic catheter placement, a long-term indwelling urethral catheter and mortality due to urosepsis. 10 It is possible to prevent or reduce the frequency of such iatrogenic urethral injuries. Interns used to receive inadequate training on urethral catheterization.…”

“…Male urethral catheterisation can be challenging due to the length and tortuous anatomy of the male urethra and pathological states such as BPH, urethral stricture and prior urological surgery. CAUI occurs with an incidence of 13.4 per 1000 male urethral catheterisations . The mechanisms for CAUI include accidental balloon inflation within the urethra, catheter tip trauma causing a false passage (most commonly in the bulbar or prostatic urethra), and traumatic catheter self‐removal.…”

“…Acute serious sequelae of CAUI occur in ~80% of patients and include life‐threatening urosepsis, severe haematuria requiring blood transfusion, and the need for urgent surgical intervention. In the long‐term, patients are predisposed to forming urethral strictures, which developed in 78% of patients after CAUI in a prospective observational study by Davis et al . The financial burden and medicolegal implications of CAUI are significant.…”

The indwelling urethral catheter remains an integral part of contemporary medical care, despite its significant design shortcomings. Urethral catheterisation is responsible for wellrecognised complications including catheter-associated urinary tract infection (CAUTI), catheter-associated urethral injury (CAUI), catheter blockage, and bladder mucosal irritation. In this narrative review, we provide an update on current innovations in urethral catheter design, aimed at safeguarding against these complications. There is an obvious need to improve catheter technology and urologists should support the translation of innovations into clinical practice.
