[Influences of renal stone surgeries on renal function--evaluation of renal function with 99mTc-DMSA renal scintigraphy].
From 1984 to 1990, 99mTc-DMSA renal scintigraphy was performed before and after nephrolithotomy (15 cases), pyelolithotomy (15 cases), percutaneous nephrolithotripsy (PNL: 15 cases) and extracorporeal shock wave lithotripsy (ESWL: 16 cases, 17 kidneys) in order to evaluate of influences of renal stone surgeries on split renal function. DMSA renal uptake change ratio of treated kidneys of nephrolithotomy (-24.94 +/- 5.60%) was significantly lower than that of PNL (-0.06 +/- 3.92%), pyelolithotomy (-4.08 +/- 4.79%) (p less than 0.01) and ESWL (-7.72 +/- 3.87%) (p less than 0.05). The average change ratios of contralateral kidneys were as follows: PNL 4.80 +/- 4.21% nephrolithotomy 4.67 +/- 4.73%, pyelolithotomy -1.46 +/- 5.39% and ESWL -2.02 +/- 4.44%. One to 3 weeks after PNL, the cold area on the renal image was found in 10 (66.7%) of 15 cases. In cases of ESWL, DMSA renal uptake decreased even 4-10 weeks (mean 7 weeks) after treatment. In conclusion, possivility of deterioration of renal function after ESWL was suggested.
