Abstract:
Objective To investigate the feasibility of urethral reconstruction with colonic mucosa graft in the treatment of complex long urethral stricture.Methods The clinical data of three cases with complex long urethral stricture were reported and analyzed.Patient ages were 71,64 and 48 yrs and the course of disease was three months,six months and six yrs,respectively.The length of urethral stricture was 13,18 and 12 cm.Removing the narrow urethral segment and intercepting the length from 12 to 18 cm sigmoid colon and stripping colonic mucosa were performed.Urethral reconstruction was done with a free graft of colonic mucosa.Follow-up included urethrography,uroflowmetry,and urethroscopy.Results The urethral reconstructions were completed successfully.The urinary peak flows of the patients were 16.7 ml/s,19.6 ml/s and 26.4 ml/s at six weeks post operation.Urethrography revealed the graft urethral lumens were bulky three months after the operation.In urethroscopy,the colonic mucosa was found to be of good color and the anastomotic site healed well.Patients were followed-up 28,16,and three months,respectively,and were all voiding well.Conclusions Colonic mucosa graft urethroplasty is a feasible procedure for the treatment of complex long urethral stricture.
