RESUMO
UNLABELLED: What's known on the subject? and What does the study add? Urethral amyloidosis is rare and urethrotomy has been proposed as a suitable treatment option. By reviewing the literature and comparing our own experiences, we have shown urethroplasty to have good medium term outcomes in patients with urethral amyloidosis, whereas urethrotomy may lead to recurrence. OBJECTIVE: ⢠Urethral amyloidosis (UA) is a rare condition which may be encountered by an urological surgeon. We reviewed the literature regarding the presentation, investigation and management of UA. PATIENTS AND METHODS: ⢠A systematic review of the English literature on PubMed was conducted and we identified 39 articles which reported 45 patients. We included our experience with four patients from our tertiary centre. RESULTS: ⢠The majority of patients reported symptoms consistent with a urethral structure. Most patients were treated with urethrotomy, only two patients have been reported to have had a urethroplasty in the literature. Medium and long term outcome data is lacking for urethrotomy and urethroplasty. We found recurrence in our patients after urethromoty and incomplete resection of UA. We describe short (6 month) and medium term (18 month) outcomes in two patients who underwent augmentation urethroplasty. CONCLUSION: ⢠Although urethrotomy and dilatation have been proposed in the past, we found these may still lead to disease progression and therefore urethroplasty may be the most appropriate long term management option.
