Objective: Renal transplantation was the operation regular in Vietnam. Urological complications following renal transplantation are low, however it may to influence on graft survival. The study evaluated urological complications following renal transplantation. Material and method: Patients were operated renal transplantation at the People No.115 Hospital from march 2004 to june 2011. The ureter was inserted into the bladder with Lich-Gregoir technique has a modification. Determine urological complications by Echo, CT-Scan, analyse urinary. Results: All 37 renal transplantations from living donor performed. The essential donor age: 20-39 (75.68 percent), Rate male/female: 27/10. The essential receiver age: 30-49 (56.75 percent). Rate male/female: 20/17. Rate nephrectomy for living donor left/right: 29/8. Rate implant fosse iliac right/left: 27/10. 100 percent cases were inserted into the bladder with Lich-Gregoir technique has a modification. 19 cases were introduced stent, 18 cases not were introduced stent. Rate urinary leaks: 1 patient (2.7 percent). Rate of urinary infection: 4 patients (10.8 percent). Not patient mortal concern urological complications. Conclusion: Rate of urological complications following renal transplantation was low. Routine Double - J stenting prevents urological complication is not necessary systematically. The anastomosis uretero-vesical with Lich-Gregoir technique was safe, capable of practice 1extensive.
