Reconstruction of the long urethral strictures with the buccal mucosal free graft.
2014
Introduction: Reconstruction of the long urethral strictures is a difficult
task in urology. The most frequently used method is augmentation with the free
buccal mucosal graft. Material and methods: Restrospective analysis of 57
patients with the long urethral stricture was performed. All patients were
evaluated endoscopically and radiologically before the surgery. Buccal
mucosal graft harvested from the inner side of the cheek (unilateral or
bilateral) was used for the urethral reconstruction in all patients.
Follow-up was one year. Results: Complete follow up is achieved in 44/57
(77.2%)patients. The most important etiology of the strictures was previous
iatrogenic trauma (instrumentation). The strictures were the most frequently
located in the bulbar urethra. Preoperative exact evaluation of the stricture
length was possible in only 35/57 patients (61.4%). Overall success rate of
the surgery was 38/44 (86.3%). Complications occurred in 6/44 (13.7%) of
patients-primary graft failure and urinary fistula. Mean preoperative IPSS
was 19,2±5,2, and postoperative 10.3±3,2 (p<0.0001). IPSSQOL was 4.9±3.7
before the surgery, 2.9±1,1 after the surgery(p<0.001). Persistent urinary
infection was present in 12/44(27.2%) patients. Conclusion: Buccal mucosal
free graft could be successfully used in the reconstruction of long urethral
strictures. However, complications are not uncommon, and residual symptoms
still exist after the surgery, and could not be neglected.
