Summary

Urethral strictures are often initially treated endoscopically with dilatation or direct visual internal urethrotomy (DVIU), a procedure where the stricture is incised through the vision of a cystoscope. These methods are easy to perform, they are often well tolerated under local anesthesia and they have a low risk of complications. One disadvantage is the relatively low success rate which is 20-60% when used as a first intervention and considerably lower after several interventions. Instead of repeated endoscopic procedures, it is advisable to perform open urethroplasty. Urethroplasty has a success rate of 65-91% but a higher risk of complications and requires general anesthesia. Therefore, there is a need for a treatment option for recurrent urethral strictures after DVIU or dilatation, before the urethroplasty is performed.

Optilume is a CE-marked paclitaxel-coated dilatation balloon used for treatment of urethral strictures. The industry-sponsored randomised ROBUST III trial from 2022 showed a 75% success rate with Optilume but it is not sure if the results can be generalised to patients who would otherwise be candidates for open urethroplasty and whether the drug coating per se increases the efficacy of balloon dilatation. The aim of this study is to investigate whether the addition of paclitaxel-coating can increase the success rate and decrease the need for additional interventions and open urethroplasty for individuals who has a recurrent urethral stricture following at least one previous endoscopic intervention.
