Background/Objectives: Lichen sclerosus is a chronic lymphocyte-mediated inflammatory disorder with a predilection for the anogenital region. It is a common cause of urethral stricture disease in males. The gold standard treatment is considered to be surgical reconstruction; however, there are many patients who are not suitable or not willing to undergo surgery. Cutaneous lichen sclerosus restricted to the foreskin, prepuce or glans is often response to topical corticosteroids; however, the use of intraurethral corticosteroids for urethral involvement has limited research. Methods: We conducted a retrospective cohort study on 18 patients with histologically confirmed lichen sclerosus and associated urethral stricture disease. They were treated with clean intermittent self catheterisation using a hydrophilic catheter coated with 0.05% betamethasone ointment. International Prostate Symptom Score with Quality of Life scores were measured prior to treatment and at follow-up intervals. Results: There was significant improvement in International Prostate Symptom Score and Quality of Life scores at 3 months, 12 months and 24 months, with only 1 patient ceasing treatment due to intolerance. One patient required a single repeat endoscopic dilatation following a period of non-compliance with treatment. Conclusions: Intraurethral corticosteroids with clean-intermittent self-catheterisation is effective and well tolerated for treating lichen sclerosus-associated urethral stricture disease in the short to intermediate term for patients not willing to undergo urethroplasty.

Urinary tract infections (UTIs) are common and troublesome complications of clean intermittent catheterisation (CIC) in individuals suffering from incomplete bladder emptying, which may exacerbate the underlying disease and lead to hospitalisation. Aside from the design of the intermittent catheter and its handling, a recent review highlighted residual urine as one of several UTI risk factors. A new urinary intermittent catheter with multiple micro-holes has been developed for improved bladder emptying. In a controlled crossover study, adult male CIC users were randomised for a health care professional-led catheterisation with the new micro-hole zone catheter (MHZC) and a conventional eyelet catheter (CEC) in two individual test visits to compare the number of flow-stops and the residual urine at the first flow-stop as co-primary endpoints. In 42 male CIC users, the MHZC resulted in significantly fewer flow-stop episodes compared to the CEC (mean 0.17, 95% CI [0.06, 0.45] vs. mean 1.09, 95% CI [0.75, 1.6], respectively; p < 0.001) and significantly less residual urine at the first flow-stop (mean 5.10 mL, SE [1.14] vs. mean 39.40 mL, SE [9.65], respectively; p < 0.001). No adverse events were observed in this study. The results confirm the enhanced performance of the MHZC compared to a CEC, ensuring an uninterrupted free urine flow with no need to reposition the catheter until the bladder is thoroughly empty.
