[Influence of extracorporeal shock wave lithotripsy (ESWL) on renal function assessed by 99mTc-DMSA scintigraphy: comparative analysis between ESWL and percutaneous nephroureterolithotripsy (PNL)].

چکیده
99mTc-DMSA renal scintigraphy was utilized to investigate the influence of ESWL on renal function in comparison with that of PNL. In the beginning, the reproducibility of renal uptake rate by the scintigraphy was examined in eleven healthy volunteers under both non-diuretic and diuretic states. The renal uptake rate was shown to be sufficiently reproducible in the same person in the two different trials. However, the differences and the standard deviations were shown to be a few percentages, which were not statistically significant. Changes in the repeated renal uptake rate seem to indicate not only changes of renal function with the treatment but also some technical errors. Herein, to investigate changes in renal function of the therapeutic side, the uptake ratio rate (rate of uptake rate in the therapeutic side/uptake rate in the contral lateral side) was utilized instead of uptake rate. Renal scintigraphy was carried out in 48 patients with unilateral renal stones before and after ESWL or PNL monotherapy or the combined ESWL and PNL therapies. Within one week of treatment, the uptake ratio rate significantly decreased in patients with PNL or the combined ESWL and PNL, although DMSA uptake rate in the therapeutic side did not significantly changes. Neither renal uptake rate nor uptake ratio rate significantly changed after ESWL treatment. There was no significant difference in changes of uptake ratio rate between Siemens Lithostars Plus and the improved Dornier HM-3 lithotriptors. This study indicated that ESWL monotherapy did not affect the uptake ratio rate, although PNL monotherapy and the combined ESWL and PNL therapies may affect the uptake ratio rate to some extent.

Between April 1986 and September 1992, 29 extensive staghorn calculi were treated in 24 patients. Treatment was with extracorporeal shock-wave lithotripsy (ESWL) monotherapy in 11, initial ESWL followed by percutaneous nephrolithotomy (PNL) in 7 and initial PNL followed by ESWL in 11. A comparison based on treatment demonstrated that initial PNL followed by ESWL resulted in a lower rate and sho...

Extracorporeal shock wave lithotripsy (ESWL) has been established as noninvasive treatment of choice for the great majority of upper urinary tract stones. However the management of staghorn stones in solitary kidney still deserves special consideration. We reviewed retrospectively 11 patients with staghorn stones in solitary kidney treated mainly with the Dornier HM-3 lithotripter during the pe...

Thirty patients (16 men and 14 women) with cystine urinary stones were treated by extracorporeal shock wave lithotripsy (Dormer HM-3) from December 1984 through October 1989. The average patient age was 35.2 years with a range of 14 to 59 years. Seventy per cent of these subjects had had previous open surgical operations for stones. The cases consisted of 7 ureteral stones and 37 renal stones, ...
