Constant perfusion provocation in idiopathic hydronephrosis

J C DjurhuusH Hvid-Hansen


Twenty-two hydronephrotic units in 20 patients underwent preoperative pressure flow study in combination with electromyographic study of pelvic and ureteric peristalsis. Ten units had a continuous pressure rise during perfusion, whereas the rest had a stabilization of the intrapelvic pressure below 20 cm. of water. The high pressure group was identical with the low pressure group concerning degree of hydronephrosis judged by intravenous urography and function judged by the two-minute uptake of isotope on the renogram. The major difference was the presence of aberrant vessels which were present in 7 of 10 high pressure units and absent in 8 of 12 low pressure units. Long-term records prior to surgery were obtainable in only 1 patient who had spontaneous progression of hydronephrosis during a ten-year period. This unit had a low pressure response to perfusion. The investigation seems to indicate that pressure flow studies might reveal external obstruction, an obstruction which might not be fundamental to the course of the disease. More studies are needed before consequence are to be taken from urodynamic studies of the upper urinary tract.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.
