  • AIMS: To compare the efficacy, complications, cost analysis and hospital stay between two methods of drainage of the kidney: double J (DJ) stent versus nephrostomy tube following open pyeloplasty for ureteropelvic junction obstruction hydronephrosis. PATIENTS AND METHODS: This was a prospective randomized study of 20 patients in each group over 14 months. Pre and post-operative (3 months) function and drainage were assessed by ethylenedicysteine scan and intravenous urogram. RESULTS: Both groups showed similar good improvement in function and drainage. Nephrostomy group had significantly longer hospital stay (P < 0.001) but incurred less cost. Complications with nephrostomy included tube breakage (n = 1) and urine leak after tube removal (n = 2). DJ stents were associated with stent migration (n = 4), increased frequency of micturition (n = 9), dysuria (n = 4) and urinary tract infection (n = 1). CONCLUSION: Both methods of drainage did not interfere with improvement after pyeloplasty. Minor complications were more with DJ stent (P = 0.0003). Although overall cost of treatment was more with stents, they reduced length of hospital stay. Optimal length of stent is essential to reduce complications secondary to migration and bladder irritation.
