IntroductionIatrogenic urethral lesion with subsequent cuff erosion during cystoscopy is a rare complication. The alternative surgical strategy with in situ urethroplasty while maintaining the open cuff left in situ will be presented. Materials and methodsThe authors report 3 cases of iatrogenic urethral lesion with cuff erosion during cystoscopic evaluation to exclude stricture or cuff erosion due to new onset of obstructive lower urinary tract symptoms. All patients had a history of a AMS 800 implantation due to postprostatectomy incontinence. Rigid cystoscopy was performed, which revealed no pathologies; however, iatrogenic small urethral lesion was identified during the removal of the cystoscope at the projection of the cuff. ResultsIn situ urethroplasty was performed, and the cuff was left open in situ. Additionally a protection fat flap was placed around the urethra from the dorsolateral aspect, separating the cuff and urethra from the direct contact with each other. After 6 weeks the urethral defect was completely healed and via a primary perineal incision the cuff was readapted and closed. The device was fully functioning without any additional adjustments. ConclusionOur modification should be considered in select cases with absence of infection as part of management strategy for cases of iatrogenic urethral lesions with subsequent cuff erosion. Thereby the original cuff can be spared and the possibly difficult preparation of the urethra during reoperation can be avoided. However, additional more cases should be presented in the worldwide literature, to confirm the utility of this surgical principle.
