[The accuracy of placental scintigraphy (author's transl)].

The results of 150 placental scans are reported, using 99mTc erythrocytes, 113mIn gelatine and 113mIn tranferrin. Accuracy was checked at surgery and compared with ultra sound findings. In 62% of patients, the indications for placental scintigraphy was suspicion of placenta praevia because of bleeding in late pregnancy. In 38% placental localisation was performed for amniocentesis for Rh incompatibility. Localisation of the placenta was accomplished in 98.6% by scanning and in 95% by ultra sound. Accuracy of scanning was 94% and ultra sound 70%. Placental scanning is at present the most accurate method for a placental localisation and should therefore be used when an accurate diagnosis cannot be achieved by other techniques.

[Urethro-cysto-colpo-rectography, a radiological method for the diagnosis of insufficiency of the pelvic floor (author's transl)].

Contrast examination of pelvic organs was carried out in 200 female patients with insufficiency of the pelvic floor. The topography of the organs in the true pelvis and their functional relation was recorded on full-size film and 70 mm. roll film. Radiological examination provides more accurate indications for plastic surgery of the pelvic floor, influences the operative procedures and permits better evaluation of operative results.

[Value of sequential scintrigraphy and clearance determination following normo- and hypothermic renal ischemia].

Using quantitative sequential camera scintigraphy and simultaneous separated clearance determinations with 131-I-Hippuran and 169-Yb-EDTA renal function was measured applying a new surgical method which permits in-situ kidney perfusion and cooling in animals and patients. While mongrel dogs of 15 kg average weight (control group of N = 5) showed after 1 hour of normothermic ischaemia a postoperative delay of intrarenal transport of 131-I-Hippuran with reduction of 131-I-Hippuran and 169Yb-EDTA clearances, renal function returned to normal on the first postoperative day after 1-hour (N = 5) and 2-hour (N = 5) hypothermic ischaemia. In patients (N = 9) with hypothermic in-situ perfusion of between 40 and 92 min duration a transient postoperative delay of intrarenal 131-I-Hippuran transport and a reduction of the 131I-Hippuran clearance was observed which returned to almost normal 1 1/2 to 3 months after surgery. The results and the significance of the method discussed and are compared with clinical findings and with radiological and laboratory renal function studies.
