Sonographic and 99m Tc DTPA Renal Scan changes in Pre and Post Percutaneous Nephrostomy in Unilateral Hydronephrotic on U/S and Non-Functioning on IVU kidneys

Abstract

15 patients who presented with unilateral non-functioning kidney on IVU and with age range 21-69 years with mean of 45 were studied. 11 patients (70.35%) were male and 4 patients (29.70%) were female with 2.31:1 ratio. 3,5,4,2, and 1 patients were from 21-30,31-40, 41-50, 51-60 and above 61 years age group respectively. 11 (73.73%) had some disease, 3 (20%) PUJ obstruction and 1 (6.6%) ureteric stricture as cause. 11 (73.3%) had no hydronephrosis and 4 had minimal hydronephrosis after PCN. Total mean GFR was 94.2, 94.4,97.3 and 98.5 ml/min in pre PCN, 2 weeks, 4 weeks and 65 weeks respectively, showing significant improvement. Final results in obstructive kidney showed no improvement in 4 (26.6%) mild (<25%) in 1 (6.6%), good (<50%) in 2 (13.3%) and excellent (<50%) in 8 (53.3%) patients. Both ultrasound and 99m Tc DTPA renal scan can play a vital role not only in diagnosing Hydronephrotic and non functioning kidney but also saving 11 (73.3%) patients from emotional as well as physical trauma of nephrectomy
