Background: Urological complications following kidney transplantation are not unusual and can be associated with risk of graft failure.
Objective: to estimate occurrence of urological complications following living donor kidney transplantation and correlation with relevant risk factors related to complications development.
Patients and methods: The current trial was achieved at urology department in the national institute of urology and nephrology and included 240 patients who underwent renal transplantation, data was collected from patient files and recorded, complications were correlated with pertinent risk factors and the influence of complications on graft survival was assessed.
Results: Urological complications occurred in 26.3% of patients. Bacterial infection was the most common early complication (in the first postoperative month) (8.8%), followed by perinephric hematoma urinary leakage, ureteral obstruction and urinary retention. Lymphocele was demonstrated to be the most common late complication (7.9%), followed by erectile dysfunction, vesicoureteral reflux and ureteral stricture. Regarding predictors of occurrence of urological complications, age of the recipient/ donor, gender of the recipient/ donor, diabetes, hypertension, chronic interstitial nephritis, lupus nephritis, double graft artery/ vein and operative duration were non-significant predictors. However, there was statistically significant correlation between occurrence of urological complications and graft survival (P-value<0.05).
Conclusion: We concluded that urological complications of renal transplantation were common (26%). Bacterial infection was the most common early complication, while lymphocele was the most common late complication. None of the potential risk factors could significantly predict the occurrence of urological complications. However, occurrence of urological complications significantly affects graft survival.
