Post renal transplantation urological complications carry a real risk of graft loss. This study explores the incidence, types, and outcome of such complications at our centre. 528 renal transplantations have been performed in 313 males and 215 females. They received kidney grafts from 384 living and 144 cadaveric donors. 69 recipients were children. The ureter of renal graft was implanted into the urinary bladder, usually over JJ stent, using simple neocystostomy technique. 23 instances of urological complications (4.3%) were detected in 18 males and 5 females, aged 9 to 58 years. Their kidney grafts were obtained from 14 living and 9 cadaveric donors. Complications were in the form of: [A] URINE LEAK: was detected in 10 recipients at 1 to 7 days after transplantation, presented with increased serum creatinine, and diagnosed by isotope renal scanning. 4 patients responded to conservative treatment, and the other 6 patients required surgical intervention. [B] URETERIC STRICTURE: was detected in 10 recipients at 2 to 76 months. It presented with increased serum creatinine. Diagnosis was made by ultrasound and isotope renal scanning. Treatment was with per cutaneous ureteric dilatation and stenting in 6, and by surgical repair in 4 recipients. [C] URETHRAL STRICTURE: was detected in 3 recipients at 7 and 64 months after transplantation. It presented by weak stream and increased serum creatinine. Patients were treated by internal urethrotomy and repeated urethral dilatation. Urological complications were rare (4.3%) in this series. Urine leak appears in early post transplantation period, and ureteric stenosis appears at a late time. Urological complications were successfully treated with no graft loss.
