ABSTRACT
Extraction of renal calculi via a percutaneous track was for the first time practised at the Karolinska Hospital in 1973. After very strict indications in the beginning because of fear of uncontrollable bleeding, the method was found to be safe and the technique was spread all over the world. Now being to a large extent replaced by extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolithotomy (PNL) has still many applications e.g. alone in obstructed kidneys or together with ESWL in staghorn calculi.

Two thousand fifty-four women were routinely screened with ultrasound in the tenth to 14th week of pregnancy. The clinical outcome was compared with a group of 1358 gravidas examined selectively with ultrasound. In the test group, 95% of all women had an ultrasound examination early in pregnancy; the corresponding figure in the control group was 50%. Neonatal outcome was similar, but the frequency of labor inductions decreased in the group routinely screened with ultrasound. Induction of labor for suspected postdatism increased the risk for emergency cesarean section in comparison with spontaneous onset of labor. In about 20% of all cases, prediction of the time of delivery was altered according to the ultrasound examination, and analysis of the patients with spontaneous onset of labor showed that ultrasound was a better predictor of the time of delivery than was the last menstrual period.

In the high risk patient presenting with jaundice, an 8 millimeter common bile duct stone was diagnosed and extracted by percutaneous transhepatic technique, thereby avoiding operation. The procedure was well tolerated, and the patient free of symptoms during a one year follow-up period.

Recurrent renal calculous disease is often troublesome to treat because of technical difficulties associated with reoperation. Attempts to dissolve the stones by irrigation with various solutions has not had much success. A new extraction technique has therefore been devised whereby the stones can be removed through a percutaneous nephrostomy umder radiological control. Three cases are described.
