Abstract


Purpose: to present a modified technique of managing extensive
penile urethra strictures with dorsal and ventral onlay buccal
mucosa grafts, following the Palminteri technique, currently
used for bulbar urethra strictures. Patients and methods: From
October 2014 to January 2016, a total of 12 patients underwent
urethroplasty for penile urethra strictures, using dorsal and
ventral onlay grafts from buccal mucosa. The mean age of the
patients was 42.75 (17-71). All patients completed the IPSS and
QoL questionnaire and uroflowmetry was done preoperatively.
After surgery, the follow-up included completion of IPSS and
QoL questionnaire and measuring of uroflow at 1, 3, 6 and 12
months. Post-operative urethrography was performed in complex
cases or in the event of deterioration of voiding symptoms.
Results: The mean length of the strictures was 5.45 (2, 2-16)
cm. Mean Qmax changed from 3.45ml/sec preoperatively to
18.33 postoperatively, and mean IPS score significantly decreased
from 20.1 preoperatively to 8.98 postoperatively.All
values were statistically significant (p<0.001). No intra-operative
or immediate post-operative complications were recorded.
Only one patient with a complex, long stricture, which involved
the bulbar urethra as well, recurred and is currently managed by
self-dilatation. Two more patients, with indwelling suprapubic
catheter preoperatively, developed urinary tract infections post
operatively and were managed conservatively with no further
sequelae. Overall, at 12 months 11 out of 12 patients (91.6%)
had a marked improvement in quality of life and uroflowmetry
parameters. Conclusions: In the properly selected patient, the
combined use of double graft for penile urethral strictures can
be successful with minimal morbidity, at short-term follow-up
