Objective: To evaluate the long-term results of repairing long anterior urethral strictures with lingual mucosa onlay grafts.Patients and methods: This study included 23 patients (mean age 36.3 years, range 21-62) who had a lingual mucosa onlay graft for managing a long anterior urethral stricture, and who were followed up for P5 years. The mean length of the stricture was 4.6 cm. The International Prostate Symptom Score and uroflowmetry values were obtained before surgery, and at 3, 6 and 12 months afterwards, and annually thereafter. A retrograde urethrogram with a voiding cysto-urethrogram was taken before surgery, at catheter removal, after 3 and 6 months, and selectively thereafter.Results: The mean (range) follow-up was 66 (60-72) months. The cause of the stricture was trauma in nine patients, instrumentation in seven, idiopathic in four, urethritis in two and previous hypospadias repair in one. The surgery was successful in 20 of the 23 patients (87%), and a recurrent stricture developed in the remaining three. There were no fistulae or clinically perceptible graft sacculations, and no longterm donor-site complications.Conclusions: With a long-term follow-up, our series confirms the durability of lingual mucosal onlay grafts for treating long anterior urethral strictures.

Background: Post Transplantation Diabetes Miletus (PTDM) is a chronic metabolic disease developed in some of our kidney transplant patients. PTDM is a chronic, inflammatory disease with a direct impact on patients' immune system. Angiopoietin and Angiopoietin-like are intrinsic mediators induced by immune cells. Objectives: To determine the relationship between circulating Angiopoietin-1 and 2 (ANG-1, 2) and Angiopoietin-like (ANGPTL 3-8) in kidney transplant patients who develop diabetes (PTDM) vs. patients who do not develop diabetes(CONTROL) after kidney transplantation. Methods: In this cross-sectional study, all patients were enrolled from Dasman Diabetes Institute Diabetes Education Department and outpatient clinics of the Hamad Al Essa Organ Transplant Centre of Kuwait between May 2015 and December 2016. The present study included 155 PTDM and 154 controls, age-and sex-matched. We collected 3 ml of venous blood from each subject. Enzyme-linked immunosorbent assay (ELISA) determined plasma ANG 1,2 and ANGPTL 3-8. We determined the correlation between plasma ANG 1 and 2 and ANGPTL3-8 levels in our PTDM and Control group. Results: In our cohorts, most of the patients (56%) were Kuwaiti. Moreover, the two groups were comparable regarding their original kidney disease, dialysis type, donor type, and the type of both induction and maintenance immunosuppression (P > 0.05). Also, pre-transplant co-morbidities were comparable in both groups, including hypertension, history of exposure to tuberculosis bacilli, ischemic heart disease, bone disease, anemia, and hyperlipidemia (P > 0.05). We found significantly higher plasma ANG-1, ANGPTNL 6, 7, 8 levels in the PTDM group compared to the control group (P < 0.001). However, we found no statistical association between our study groups concerning plasma ANG 2, ANGPTNL 3, 4 (p>0.05). Conclusion: Plasma ANG 1, ANGPTNL6, 7, 8 levels may correlate with disease severity, chronicity in transplant patients who develop diabetes post Kidney transplantation, and serve as a potential biomarker of the disease severity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
