ObjectiveTo prospectively evaluate the feasibility and initial results of an everted saphenous vein graft (eSVG) as a dorsolateral onlay, in patients with long anterior urethral strictures and/or chronic tobacco users.Patients and methodsIn all, 20 patients with long anterior urethral strictures (>7Â cm) and/or chronic tobacco exposed oral mucosa were included in the study. The harvested SVG was hydro-distended, detubularised, and everted. Substitution urethroplasty using an eSVG was performed using a dorsolateral onlay technique. Symptoms were assessed using the International Prostate Symptom Score (IPSS) and uroflowmetry at 1, 3 and 6Â months; and voiding and retrograde urethrograms, and urethroscopy were done at 3Â months. Failure was defined as failure to void, need for interventions in form of direct-vision internal urethrotomy or endodilatation.ResultsThree patients were excluded because they underwent a staged urethroplasty. In all, 17 patients underwent eSVG substitution urethroplasty. The mean (SD, range) follow-up of our patients was 17.64 (5.23, 10-26) months. The mean (SD, range) length of the strictured segment was 14 (2.5, 10-18) cm and the length of the harvested SVG was 16.3 (2.7, 12-20) cm. The mean (SD) IPSS at 1, 3 and 6Â months after catheter removal was 10 (2.8), 10 (3.4) and 10 (1.4) and the quality-of-life score was 1.76 (0.5), 2.05 (1.0) and 2.05 (1.0), respectively. Postoperatively, endodilatation was required in two patients. Complete failure occurred in one patient.ConclusionsAn eSVG, as a dorsolateral onlay graft, is a promising and prudent option for long anterior urethral strictures, especially in patients with poor oral hygiene and chronic tobacco use.
