AIMS AND OBJECTIVE:To compare the outcome of percutaneous nephrostomy versus double J ureteral stenting in the management infective hydronephrosis in calculous disease.
MATERIALS AND METHODS:From October 2012 to January 2014,40 patients of age 25-65 years with obstructing ureteral or renal pelvic stones with clinical signs of infection were underwent decompression by double J stenting(20 patients) or percutaneous nephrostomy (20 patients) in this study. Patients with single calculus of size less than or equal to 15mm with fever and white blood count (WBC) of 14000/ mm 3 or greater were included in this study. Calculus size greater than 15 mm, patients with bilateral or multiple calculi, pregnancy, ureteral or urethral stricture disease, uncorrected coagulopathy, Patients with solitary kidney were excluded from the study. Outcome parameters included time to achieve normal temperature and WBC of 11000 /mm 3 or less, and resolution of pyuria if present were analyzed in both group of patients. RESULTS: Majority of the patients were between 25 to 65 years of age with male to female ratio was2.12:2.87.The most common location of stone was at distal ureter in either group. There was no significant difference between pre procedural WBC count, maximum temperature and stone size in either group. Procedura land fluoroscopy times were significantly shorter for double j stenting (30.95±6.02 and5.3±3.2) compared with percutaneous nephrostomy (35.9± 5.4 and7.2± 4.2). During drainage the appearance of the urine was grossly purulent in 5 patients (12.5%), turbid in 19 (47.5%) and clear in 16 (40%). Overall urine cultures and blood cultures were positive in 50 and 12.5% of patients, respectively. Urine cultures were positive in 60% of the percutaneous nephrostomy compared with 40% of the double j stenting group (p not significant). There was no significant difference in time to clinical improvement (Time to normal WBC and temperature and time for purulent drain to clear) between the 2 groups. CONCLUSION: There is no significant difference in the efficacy of relieving obstruction/symptoms in either procedure. We feel the choice of choosing a particular procedure depends on site of stone and degree of proximal obstruction. However prior PCN facilitates easier PCNL.
