Plastic surgery in hydronephrosis (Indications and follow-up. Isotope nephrographic studies).

Surgical interventions for the reconstruction of the renal pelvis were performed in 108 cases between 1962 and 1974. On follow-up, 3 to 6 months after operation the results were found good or satisfactory in 54 cases (50%). Isotope nephrography revealed a good or satisfactory fall of the curve in the excretion phase in 49 out of the 54 cases (94%), distinct retention curves having been found in the remaining 6%. In 35% of these cases isotope nephrography showed a far more complete urinary drainage than it had been assumed on the ground of radiography. In 63% of the cases the results of the two diagnostic methods were congruent.
