Objective : To review our experience with ureterocalicostomy using the treatment of com plicated ureteropelvic junction (UPJ) obstruction.
Materials and Methods : Medical records of all patients with complicated ureteropelvic junc tion obstruction treated by ureterocalicostomy from 1985 to 2000 were reviewed. Causes of UPJ obstruction, surgical techniques, peri-operative course and outcome were noted.
Results : Fifteen patients were enrolled in this study (6 males and 9 females) with the mean age of 39 years old (28-45). Twelve patients were after stone surgery, 2 were after pyeloplasty for congenital UPJ obstruction and one patient was after blunt abdominal trauma. All the procedures were done by flank incision. After excision of the lower pole, the ureter was anastomosed to the lower caliceal mucosa without tension over an internal stent. Nephrostomy tubes were used in all of the patients. The mean hospital stay was 14 days (10-20). Twelve cases (80%) were found to be successful and are still doing well with the mean follow-up time of 2.5 years (0.5-12). Three patients (20%) were found to have failed, and subsequently nephrectomy was done in one case and permanent nephrostomy was used in 2 cases due to a solitary kidney.
Conclusion : Ureterocalicostomy is one of the options for treatment of complicated UPJ obstruction that can provide good drainage as well as excellent long term results.
